The 13th Miklós Iványi International PhD & DLA Symposium is one of the most important scientific events at the Faculty of Engineering and Information Technology, University of Pécs. The Faculty hosts the meeting for young researchers and their professors. After the loss of the founder of this Symposium, Prof. Miklós Iványi, it has been decided to honour his memories and therefore this event will be named as "Miklós Iványi International PhD & DLA Symposium". This is the 13th year that the PhD & DLA Symposium gives an opportunity to present the achievements of young researchers, to exchange information about the researches of the international partner institutions and to exchange valuable professional experiences and cultivate real friendships. This Symposium is part of a series of events to celebrate the 650th anniversary of the foundation of the University of Pécs as the first university in Hungary. At the end let me greet the participants of the 13th Miklós Iványi International PhD & DLA Symposium and express my thanks to the organizers for their activity and to the participants of the former and this year’s PhD & DLA Symposium to present papers. At the same time I wish you the best to continue with successful work.

HIGHER EDUCATION IN THE UNITED STATES WITH FOCUS ON MSU-U PÉCS PARTNERSHIP Stephen M. JORDAN, PH.D. Immediate Past President, Metropolitan State University of Denver Denver, Colorado, USA
Stephen M. Jordan has been president of Metropolitan State University of Denver since July 2005. Since taking the helm, Jordan has led MSU Denver on a rapid trajectory toward becoming one of the preeminent public urban universities in the nation. Under his leadership, MSU Denver has achieved university status. In addition, the University has been recognized locally and nationally for the value of its degrees as evidenced by the return on investment its graduates attain. In an environment of deep budget cuts, Jordan has led nationally recognized initiatives to retool and reposition the University for the future. The University is currently pursuing additional partnerships to complete its community Athletic Complex and construct an interdisciplinary aviation/advanced manufacturing academic building that will educate Colorado’s advanced industry workers of tomorrow. During his seven years as president of Eastern Washington University - before coming to MSU Denver - he grew the University from 6,900 students to over 10,000 students and repositioned the university from a commuter institution to a residential university. Jordan was one of sixteen presidents in the United States recognized in the book The Entrepreneurial President for his entrepreneurial approach to innovation and change. Jordan grew up in Colorado. He holds a bachelor’s degree from the University of Northern Colorado and a master’s degree and a doctorate in public administration from the University of Colorado Denver. He and his wife Ruthie have two sons, a daughter and six grandchildren.

Abstract Less than 20 years ago American universities were preeminent in the world and our graduates were eagerly sought after throughout the world. The United States, which led the world in access to higher education for decades, is now only 14th among 37 OECD countries in the percentage of 25 to 34-year-olds with higher education attainment, at 42 percent. We are not growing that percentage fast enough. (http://www.oecd.org/education/CN%20-%20United%20States.pdf) From the Congress of the United States, to state Legislatures, to the parents of America’s students – and certainly among those of us who provide the education – everyone is concerned about the state of our higher education system. In a study by Georgetown University’s Center on Education and the Workforce, there will be 55 million job openings in the U.S through 2020 and 35 percent of them will require at least a bachelor’s degree while 30 percent will require some college or a twoyear associate’s degree. But getting a university education is not just about jobs. The facts are quite clear that higher education has many other benefits for individuals and communities. People with more education earn more and they are also healthier, have lower unemployment, incarceration rates and participate more in the world around them. If higher education is so beneficial, why has the United States fallen behind? People who are involved in higher education have different takes on the specific sources of the problem, but in most cases they can be traced back to one key element: money. The National Center for Education Statistics reports that in the decade between 200405 and 2014-15, prices for undergraduate tuition, room and board at public institutions rose 33 percent. Meanwhile, government support for higher education has fallen. In the United States, most of the government support is provided at the state level, and for several years because of economic pressures, higher education has been cut back repeatedly. According to the publication Inside Higher Education, 44 states are spending less on higher education in 2017 than they did before the Recession. Work is underway to change the national picture. Started by the Obama Administration a menu of higher education reforms have been proposed that would improve accessibility and affordability while providing the accountability that our political system increasingly requires – in other words, to make sure that the taxpayers are getting value for their investment. While there is a new Administration in place, it has not articulated a different or specific higher education agenda other than reducing regulatory oversight. There have been an array of initiatives at the Federal level, including: • A national system of rating all institutions of higher education with metrics on affordability, graduation rates, student debt and initial starting salaries upon graduation which is available to the public on-line. • An increase in Federal Need Based financial aid, the Pell Grant. • Reduction in student loan interest rates. xxii
PLENARY LECTURE
• An increase in Work Study, university student employment, for students with documented need. • A Federal competition grant program, Race to the Top: College Affordability and Completion, to incentivize states to constrain costs and improve performance. Colorado and several states have already put plans in place to improve college access, retention and graduation. Colorado’s Master Plan for higher education was passed last December. It calls for between 60 and 63 percent of the adult population achieving college goals by 2020. Many states, like Colorado, have simultaneously implemented performance measures to require institutions of higher education to increase the number of degrees awarded, improved student success through enhanced remedial education and student support services in order to reduce the time to degree and, reducing the educational attainment gaps among ethnic and low income groups. The United States is proud of its heritage as a “melting pot” of cultures, races and ethnicities. The recognition is growing that our economic future rests on seeing to it that these students – many of whom also are low-income and first-generation-to-college individuals – receive college educations. Congress has appropriated modest additional funding for strengthening Minority Serving Institutions and Hispanic Serving Institutions. These are colleges and universities that have achieved a required percentage of full-time minority students. At MSU Denver we’ve been working toward becoming a Hispanic Serving Institution since 2007 and this fall we achieved the goal, which was to have 25 percent of our students be of Hispanic origin by 2018, a year early. Like much of Europe, a fierce debate is going on in the United States about immigration in general, and as part of that, what to do about educating undocumented youth – young people who are in the United States largely because their parents thought they would have better opportunities by immigrating, even illegally. About 65,000 of these young people graduate each year from U.S. high schools. They are primarily Hispanic students. While Congress has failed to pass the Development, Relief, and Education for Alien Minors Act – known as DREAM, 13 states have gone ahead and acted on their own to provide the same tuition rate to these students as their citizens receive, making higher education a bit more affordable. While not articulated as an higher education initiative, the new administration’s efforts to restrict immigration are raising significant concerns within institutions about their ability to continue to enroll significant numbers of international students, particularly at the graduate level. These concerns are particularly acute as they relate to Middle Eastern Countries that have been specifically targeted for “extreme vetting” by the Administration. Higher education institutions in America strongly believe in the importance of engagement with the rest of the world and the need for our students and faculty to have opportunities to exchange cultural and pedagogical insights and knowledge. Consequently, during a period in which immigration may be more tightly controlled, significant meaningful partnerships with institutions, such as that between the

University of Pecs and Metropolitan State University of Denver, will play increasingly prominent roles. If American higher education is going to meet the workforce goals, colleges and universities can’t wait for the students to come. So, we’re trying new ideas. Right now in higher education Throughout the country there is great attention on the potential of massive online open courses, or MOOCs. Could these online courses revolutionize the way higher education is acquired? University of Virginia Professor Siva Vaidhyanathan notes that so far the most successful MOOCs have been offered in the “math and computation” -based fields and are vocational, rather than exploratory, idea-based or that require laboratory experiences. A study of a million MOOC users by the University of Pennsylvania found that only about four percent of the people who registered actually finished their courses. And in another study by the same university it was revealed that about 80 percent of the people who took Penn’s own MOOCs already had a college degree. Even if they ultimately achieve great success, MOOCs are just one part of a growing online educational landscape. Offering college courses online is one path to more higher education affordability and access. At MSU Denver we don’t offer MOOCs, but we’re like many other universities in offering online education, because it provides our students flexibility. This fall at MSU Denver, for example, we had over 7,000 students taking online and hybrid courses. Our online and “blended” or “hybrid” courses are offered through a learning management system that allows online students to interact with their professors and other students through chat, text messaging and emails. Quizzes and tests may be posted for students and assignments can be given and received through the learning management system we use. Throughout the country there has been a call for more community collaborations, particularly through Public-Private Partnerships. Identifying the needs of our communities in concert with its leaders, and developing academic programs to respond to them is a key responsibility of educational institutions in the 21st century. By working alongside business and industry we are developing programs that help us bring in important financial support so we can be less dependent on government funding. For example, MSU Denver has created partnerships with leaders in some of Colorado’s major industries. We’re engaged in an exciting collaboration to integrate basic science, aviation and aerospace science, engineering technologies, industrial design, and advanced manufacturing disciplines in one new facility. We’ve developed an innovative, hands-on program in partnership with the hospitality industry – owning a for profit hotel in partnership with a private company to train hospitality students - a natural in Colorado, where tourism is the second-largest industry. Every public university is looking to and into its community to see where synergies can be found. The Coalition of Urban and Metropolitan Universities reports that 82

percent of its members are involved in partnerships for workforce development and job training. These partnerships help our students and make us better neighbors. This is the new road that higher education in the United States must take: more innovative, more entrepreneurial, more attuned to the needs of the global marketplace and our own communities. The economic shifts taking place in the 21st century are prompting us to reexamine what we’re doing and how we’re doing it. Other countries that have relied largely on American higher education to fill the need for their college-educated workers are building their own higher education infrastructure and are becoming educational competitors. We may be friendly competitors, but we will be competing. I think it’s a healthy challenge for all of us.

Foreword The 13th Miklós Iványi International PhD & DLA Symposium is organized because it is thought that PhD&DLA students need a special forum in addition to their PhD&DLA program to present the results of their ongoing research. Furthermore the results should be discussed collecting proposals how to continue the work. The First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth, Nineth, Tenth Eleventh and Twelfth International PhD&DLA Symposia were organized in 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 and 2016 and it is important to continue this tradition. Objectives of the PhD&DLA Symposium: • • • •
to provide a forum for PhD&DLA students in engineering to present the progress of their work; to discuss the results of the ongoing PhD&DLA studies in order to support the future activity; to give the opportunity for PhD&DLA students to establish contact for international communication; to compare PhD&DLA studies in various countries.
The system of this symposium is to have oral presentations by the PhD&DLA students themselves, which are immediately followed by discussions that are scheduled in the program. Main results of the studies are summarized in the Pollack Periodica (an International Journal for Engineering and Information Sciences) published by Akadémiai Kiadó. On behalf of the Organizing Committee, I would like to express thanks to the University of Pécs, Faculty of Engineering and Information Technology for hosting the Symposium.

Reinforcement learning in process scheduling ÁBRAHÁM Gyula*1, WERNER-STARKAND Ágnes*, DÓSA György* and DULAI Tibor* *
Department of Electrical Engineering and Information Systems, University of Pannonia, Veszprém Hungary
Index Terms: process scheduling, optimization, reinforcement learning, assignment problem
In process scheduling problems one of the most important factor is time. The main goal of time based scheduling is to minimize the makespan of the processes. In most cases some heuristic methods are used to solve the problem. In our work we have several processes and resources. The latter can be allocated to the tasks of the processes. To find a good resource allocation means optimal or close-optimal solution we use a special field of artificial intelligence. This is called reinforcement learning and in this approach the goal is to teach the system to find an acceptable solution.

A laboratory study of pH and salinity effects on stability of clay minerals in siliciclastic rock regarding formation damage assessment AHMAD, Khabat M.*1 and KRISTÁLY Ferenc* *
University of Miskolc, Miskolc, Hungary
Index Terms: Formation damage, pH and salinity, Clay minerals, petrophysical properties
In petroleum engineering, clay minerals have been considered one of the most important factors reduction of permeability (formation damage. Formation damage is a common problem in petroleum reservoirs, and occurs in different stages of reservoir development from drilling to production. The causes of formation damage include particle invasion, formation fines migration, chemical precipitation, and pore deformation or collapse. The extent of formation damage depends on fluid properties, rock properties and rock-fluid interaction. It impairs the permeability of reservoir rocks, thereby reducing the natural productivity of reservoirs. The migration of fines within porous media has long been recognized as a source of potentially severe permeability impairment in reservoirs. This reduction has a strong effect on relative permeability of the reservoir rock. The brine composition is one of the primary factors that determine the migration and swelling of clay particles In this paper we highlighted the effect of clay mineralogy and the influence of physico-chemical factors on coagulation- dispersion processes and the rate of pore throat bridging by internal clays. In particular we describe the effect of different pH (strong acidic 2.5 and strong alkaline 9.5) and the effect of salinity (NaCl) on the stability of clay particles in sandstone reservoir rocks and their influence on the rock permeability which are often ignored in reservoir engineering literature. We conducted the experiments on powder (0.050.1 mm grain size) samples for tracking mineral reactions and core plugs for permeability. X-ray diffraction (XRD) was run for whole-rock and clay fraction by diagnostic treatments. In strongly acidic solution, according to XRD, smectite is altered (14Å peak vanishing), chlorite being also partly reduced, while kaolinite is stable. Carbonates are not involved is reactions. In basic solution, smectite was less affected, but chlorite peaks indicate structural transformation. The shape and broadening of 10 Å peak shows changes in illite and illite/smectite interstratified structures. Altogether, mineralogical changes indicate reactions which can lead to fine particles (clay and non-clay minerals) mobilization. Based on experimental work, permeability reduced about 39% for acidic and 75% for basic solutions

Index Terms: Living commodity, living area, heated area
Living commodity is one of the main components that reflect on social and psychological state of different societies. Living commodity, besides of being a fundamental requirement of a modern human, it is also an indicator of economic and social effort. Since developed countries and countries in transition experience different political, economic and social progress and approach, living commodity may be considered as a luxury in some cases. Prishtina is a capitol of a Kosovo that is in process transition after a post war period. Although the country is on its developing stages, still it inherits an absence of components that create living commodity. Parts of southwestern Balkans with continental climate still share the same situation of living commodity in relation with heating commodity. This paper aims to identify the main components of living commodity within dwellings, covering the residential sector of city of Prishtina, based on data gathering and analysing. Current data for specific components of living commodity are compared to regional and global situation of living commodity by taking into measurement living area per capita, heated area, income per household and heating resource.

Corrosion of glass used for radioactive waste disposal AL DABBAS, Ali*1 and KOPECSKÓ Katalin* *
Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: durability and corrosion of glass, nuclear waste immobilization and deposition, radioactive waste glass container
The Spent Fuel generated from the nuclear power plants is considered as High Level (radioactive) Waste (HLW). It requires sophisticated treatment and management to be successfully isolated from the biosphere because it contains radionuclides involved in fission reactions such as plutonium, minor actinides and fission products. HLW is usually deposited in deep geological formation in multi-layer containers. After evaporation of the volatile radionuclides it is immobilized and vitrified by incorporating into borosilicate glass matrix (R7T7). The glass matrix become as spent fuel pellets poured into stainless steel containers to facilitate its handling, storage and disposal operations embedded in concrete or directly in claystones. R7T7 glass represented and studied by the inactive SON68 reference glass In our research work corrosion of nuclear waste glass in unsaturated conditions will be studied. Microorganisms from the geological environment cause anaerobic iron corrosion. Sulphate Reducing Bacteria (SRB) might corrode the steel shield layer which surroundings the nuclear waste. The steel corrosion products such as iron carbonate and free protons is expected to influence silicate (Si) sorption and iron silicates formation, thus; nuclear glass corrosion is expected to start after accelerated glass dissolution/ hydration due to Si consumption and gel layer formation, and ion exchanges between alkali or alkaline-earth ions and protons. Temperature and pH should be controlled because it affects solubility of silicate. Based on the results of the planned study, it is expected to determine the alteration kinetics and durability of the SON68 reference waste glass and the permeability of the host rock in such conditions. Experiments will be conducted with small polished glass chips, involving accelerated ageing of glass due to environment provided by the microbial activity. The nature and extent of corrosion will be determined by characterizing the reacted glass surface and volume with scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS) and Raman spectroscopy.

The industrial and office establishment in process, in Marcali is a special project of many points of view. On the one hand, we adopted principals and procedure of ENERGIA DESIGN methods within the planning process to reach energy efficiency and high comfort level. On the other hand, we faced a relevant and for the building industry characteristic challenge: The building had to ensure the most economic cost efficiency. Thermal models were created about the different planning versions of the project within dynamic energy and climate building simulations. The contractor’s existing, conventional industry hall made last year, had been compared with the new Marcali building model that is planned by ENERGIA DESIGN principals. The results of the simulations confirmed that the new building possesses significant better energy and climate performance. The building has special strategy of room organisation and climate zoning in accordance with the building. In addition it is able to naturally ventilate and light the most important central space, the workshop hall with aerodynamically planned special shaped wind deflector ‘Venturi’ roof structure. The new facility is currently under construction. After completion of implementation, the building’s consumption and indoor comfort parameters should be compared with calculation results for calibration and validation purposes.

†Studio
Index Terms: energy saving; energy efficiency; sustainability; building
Energy saving measures can play a significant role for lowering energy consumption and energy costs, as well as for environmental protection. In order to maximize the energy efficiency of a building-based on the capabilities of the existing conditions and infrastructure, and to minimize the need of any reconstruction or energy saving measures the development of an Energy Management Program for the building will be part of the paper and studies. The present situation in public Buildings, focused in Case Study: Hospitals and Medicine Institutes need the emergency activity in improvement the conditions in the field of sustainability and energy efficiency, with a focus on public buildings. This has been achieved by making use of the evidenced parameters of existing state and based on the preliminary energy audit of buildings. All the materials included in the analysis have been reported from audit and several key aspects of the research paper are oriented in Sustainability, Energy Conservation, Energy Efficiency and Buildings improvement parameters. The energy management program for this type of buildings or group of buildings usually include: - Energy inspections and energy book keeping aiming at recording the evolution through time of the energy consumption and identifying the energy saving potential of the building - Identification of the adequate targets for energy consumption - Feasibility studies for concrete energy saving measures, including the implementation of new energy technologies (e.g. cogeneration, central automated management systems, RES technologies etc.) - Energy book-keeping for registering the energy consumption of the building - Development of energy reports, periodically, targeting the manager of the building - Implementation and monitoring of an Energy Management Program for the rational operation and use of the building’s infrastructures (heating, cooling, lighting, hot water) and the electric and electronic equipment The most active categories in those fields are engineering, social and environmental sciences issues in that order. It can be assumed that the study of sustainability and energy efficiency across all its dimensions is of great interest for the scientific community. The global environmental issue has led many countries to incorporate a wide range of Energy Efficiency (EE) strategies in order to reduce energy consumption in public buildings, a highly valued aspect by European Union energy labelling.

Teaching during building! BERTA-SZÉNÁSI Panna*1 *"Education

Index Terms: built environment, education, competences
Architecture is quite a significant segment of social spatiality, and it concerns everybody. To the term spatiality, however, any societal field could be connected [1]. Hence any research of architectural phenomena could involve the study of all kinds of social mechanisms. Therefore the description of the characteristics of a building might be just as much complex a task as the characterization of a person The similarity between buildings and people is hardly questionable, as so is the general principle that all that people create around themselves will always show the relation to their creator. The quality of our built environment, therefore, reflects our thoughts, acts and esthetics, and could be considered as the accumulation of our acquired knowledge and experiences. The process of shaping our living space is therefore highly connected to the skills we acquire and the way we acquire them. When we interpret our surroundings, at the same time, we study the network our own competencies as well. This is where the interdependency of architecture and pedagogy – in the focus of this paper – can clearly be detected. Throughout my research, I analysed the work, policy and documents of a – strictly speaking – architectural studio, called Hello Wood, which I was initially interested in only for the problems it raised in connection with our built environment. Later, however, I came to know the philosophical layers and even later another, pedagogical dimension started to take form. During which process – albeit indirectly – all the nine competency fields that were introduced throughout my studies and their respective activities were clearly detectable. Over the course of my analysis, I came to the hypothesis that the approaches and tasks of the designer and the teacher prove to be quite similar, or even identical in nature. A possible way of continuing my research could be studying the impact of those practices on the development of reflective thinking that are deployed in the process of understanding the built environment. In this proposed study, special emphasis should be laid on the following two problems: what kind of educational and teacherly competencies can be aligned with the interpretation of the built environment and how these competencies could be applied in educational practices.

Index Terms: living space, interior design, future living
50% of the population is living in cities, which number will probably have increased to 75% by 2050. It means that the area of cities might grow with a sesquaialterous proportion, so 3 billion people will need certain forms of housing in cities. Regarding the increasing number of residents, most of the cities expand their area horizontally. This form of evolution requires new road networks and a developed infrastructure. The construction of new roads means more cars, which does not only result in more CO2 emission, but it also wastes our precious time. As cities are stretching, we are constantly losing our natural green areas. If we mean to preserve our national heritage and the urban green spaces, as a good solution, we need a human scale and vertical expansion in terms of urban development. Moreover, the ecological footprint could also be reduced in this way. A great majority of people live rather in a house with garden or condominium with a few residents. Merely 30% of them choose to live in a block of flats. Due to the aforementioned reasons, we should apply different features from different forms of housing in these high-rise buildings and we should also provide distinctive types of flats to create a more diverse range of choice in case of choosing a home.

Index Terms: AI based, machine learning, hydrate
During the production of gas one of the major problems is the formation of hydrate crystals in the pipeline. When a huge amount of hydrate crystal is formed, it can cause hydrate plugs in the pipeline. The hydrate plug effect lengthens the duration of production outages and results in loss of money for the maintainer, since the cleaning of the plug is a time consuming procedure. One of the used solutions to prevent hydrate formation is addition of chemical compositions to the gas, by an injection system. To determine the optimal dose, not only the hardware of injection system is important, but its software as well. In addition to the traditional control, a preventive inhibitor dosing system can be developed, which is based on a model driven system. The nature of the model is highly influential on the quality of the control system. In the presentation a machine-learning based predictive detection system is introduced.

Index Terms: vr, virtual laboratory, web, simulation
The aim of this paper is to introduce the design steps and implementation details of a virtual laboratory system, which combines modern web-technologies and open-source simulation software to create a virtual laboratory framework. In order to validate the functionality of this framework and to demonstrate its capabilities, a classic problem from the field of control theory, the inverted pendulum is implemented as an interactive demo experiment using the new framework. In this experiment, a simulated controller keeps the rod of the inverted pendulum in the upright position. Users can change different parameters of this controller and then test the impact of these changes in a very intuitive and interactive way, by applying force to the pendulum model in 3D and observing the behaviour of the controller.

Index Terms: groundwater, small hydropower plant, modelling, TRIWACO
The locality near the town of Banská Bystrica (Slovakia) was selected, based on the study of the hydroenergetic potential of the Slovak republic and on the engineering-geological survey, for the construction of a small hydropower plant. In the process of the environmental impacts assessment, it was necessary to determine the impact of the proposed hydraulic structure on the groundwater level regime of the adjacent area. Therefore the mathematical model of the groundwater level and flow before and after the construction was created. TRIWACO software, which is based on the finite element method, was used for creation of the groundwater model. The model served also for the proposal and assessment of measures that would minimize the potential negative impacts on the groundwater regime. During the phase of the project design, not all of the suggestions have been accepted. After the construction of the small hydropower plant, the groundwater level in a backwater area started to rise (as it was predicted in the model). The missing protective measures and the increasing of the groundwater level is now causing problems to residential houses located in a terrain depression in this area. The houses have their foundations in a relatively shallow depth and therefore they are in a permanent contact with the groundwater. The mathematical model, created before the realization of the hydraulic structure, is now used and recreated for designing measures, which will help to protect the houses against wetting.

Index Terms: waterfront industrial zone, landscape revival strategies, landscape ecology restoration, composite functions, walking system, open space structure, sight line organization, industrial symbols
There are three different stages of urban waterfront spaces in the history of human development. The forming stage of urban waterfront space was in the former industrial era. Waterfront space characterized by natural development, had both port function and urban public space function. The utilize stage of urban waterfront space was in the era of industrialization. Waterfront space with factories, docks and warehouses as landmark, was the core of urban production and transportation, living space was excluded. At the same time, waterfront space was serious polluted by industrial wastewater, waste and garbage emissions. In the era of post-industrialization, urban waterfront space gradually declined and into the redevelopment stage. Industrial, transport facilities and port were moved away from the city center, leaving a large number of abandoned industrial sites. These industrial sites which recorded the trajectory of urban development and people's memory of industrial production and life, is an important part of urban heritage. As a blend of artificial landscape and natural landscape area, waterfront area has significant ecological value and recreational value. Meanwhile, the waterfront industrial zone, which usually located in the center of the city, also is the main carrier of the city's image. Therefore, the urban waterfront industrial renewal and redevelopment has become an important issue of urban development. Landscape is the most important means to organize public space and stimulate the vitality of the venue. Landscape revival strategies of urban waterfront industrial zone were summarized based on the analysis of the design of the Baltimore tide point and Hudson River Park in the United States, the Rehabilitation of Deal Pier in UK, the reconstruction of the Qishan Park and Huangpu Riverside Industrial Site in China. Including improve the water quality and restoring landscape ecology; reuse the key architectural heritage and join composite functions such as commercial, leisure, exhibition, catering and so on; add public transport and walking system combine the waterfront recreation space with urban public space and green space to form a structure system of urban open space; organize the sight line from the city to waterfront and in the waterfront area; improve the environment quality of public space, transform the industrial symbols to design elements, to create a unique site spirit and historical atmosphere.

Index Terms: occupant behaviour, energy consumption, office buildings
In recent years, both legislative instruments and market demand drive the construction industry towards high-performing, low-energy consuming buildings. However, without considering the human dimension, technologies alone do not necessarily guarantee high performance in buildings. Occupant behaviour in buildings is a leading factor influencing energy use in buildings. To investigate and quantify the human dimension in a building’s energy use, an international research study has been launched as part of project IEA EBC ANNEX66 using an interdisciplinary framework. The framework is a synthesis of theories from building physics and social psychology including social cognitive theory, the theory of planned behaviour, and the drivers-needs-actions-systems ontology for energy-related behaviours. As a research tool, an online survey was designed to collect cross-country responses from office occupants among 14 universities within 8 countries from 4 continents. This paper introduces results and findings of the Hungarian data collection campaign conducted among 245 occupants in 5 universities across the country. Results show that 88% of the occupants have access to operable windows and use them frequently which imply a great effect on the energy balance of office spaces.

Index Terms: eccentrically braced frames, multiple longitudinal stiffeners, buckling resistance, seismic links, cyclic ductility
This paper provides and introduces an overview of the innovative structural solution for dissipative seismic resistant eccentrically braced frames ( EBFs) structures. Within the last ten years, EBFs have become a widely recognized lateral load-resisting system for steel buildings in areas of high seismicity A steel seismic link is created using multiple longitudinal stiffeners enabling the web plate for overall buckling behaviour, which is beneficial with respects to ductility. Buckling resistance of thin web plates of I girder can be significantly increased by application of stiffeners in the web. Vertical stiffeners are often required in seismic links of eccentrically braced frames, but rarely used in moment resisting frames. Such stiffeners are typically designed as relatively stiff and strong stiffener that is resulting in relatively low ductility. To study the cyclic behaviour and ductility of such girders, numerical model is developed. Cyclic ductility is studied and compared at different stiffened geometries. The obtained results confirm the practical applicability of the conceived configurations of flexible multiple stiffeners. The results also provide as the basis for further design provision development.

Index Terms: innovative board, surface temperature, infrared heating, construction
The construction is characterized from construction processes point of view by high proportion of manual work. The processes are interconnected and interacted. The human factor greatly affects the efficiency of construction work, therefore it is necessary to develop and use construction products which eliminated manual work. The paper presents partial results of research and development of innovative board with built-in infrared heating foil. Nowadays, this board is protected by valid utility model. Innovative board fulfils the construction and heating functions at the same time. The montage of the construction board and heating system is realized in one construction process by using this innovative board. An innovative board can be built into the floor, wall and ceiling, or used as a bearing board with heating function within a structural insulated panel (SIP). The aim of technical solution of innovative board is enclosed by the infrared heating film between two construction boards. The innovative boards are then interconnected to the heating system during the realization. The methodology for measuring the surface temperature of the board was determined as a part of the initial research of the innovative board. Surface temperature sensors were used for measurement and they were placed symmetrically on the surface of the board. Time required to achieve the reference surface temperature of the board was investigated on the selected boards (oriented wood strand, gypsum and magnesium oxide board) after switching on the heating foil. The board and the foil were placed on the insulating pad (fig. 1). Based on measurements it was found that the gypsum board needs the shortest time to reach the reference temperature when the heating film is switched on compared to the other plates. The magnesium oxide board needs the longest time to reach the reference temperature. On the other hand, after stabilization of temperature, the maximum surface temperature of the magnesium oxide board was higher than the surface temperature of the other plates. The results of partial measurements offer the basis for further analysis and research of the innovative board with built-in infrared heating.

Urbanization and the growing migration from rural areas to cities set pressure on the residential building in Egypt. Moreover Central Agency for Public Mobilization and Statistics (CAPMAS) estimated that the number of Egypt's population has raised from 72.8 million people in 2006 to 90.1 million people in 2016. Therefore, the government started to solve this problem by constructing 13 new urban communities. New Minia considered as a part of this planned project. New Minia characterized by hot-arid climate. Although Egypt has a spare operational capacity of oil supply in comparison with other countries around the world, it suffering from energy shortage and the energy prices have been raised strongly and it is estimated that it will continue to rise in future years. Therefore, a significant need for energy efficient design strategies for residential buildings in this region has become more essential in order to help decreasing demand for active heating and cooling. Climatic design strategies are effective in reducing building energy consumption. This study analysed the existing family house in New Minia region (Upper Egypt) by using IDA ICE 4.7.1 software through the assessment of energy and comfortable performance. Also this research studied the effect of building orientation on energy consumption and thermal comfortable. The results showed that this building consumes a lot of energy due to improper construction technique and limitation of used isolation material. The orientation of building has a significant effect on thermal comfortable.

Production management has a significant impact on the economy of most firms. In the real world management also has to deal with multi-period production problems, where the actual demand, the production capacity or even the storage capacity may vary according to some parameters during the time horizon. One of the solution methods of the unconstrained version of these problems originate in 1958, when Wagner and Whitin proposed their dynamic lot size model as well as an algorithm, called the Wagner-Whitin algorithm. Subsequent generalizations and modifications of their proposed method are available; however, finding an effective solution of the constrained situation where the production capacities vary widely according to the available resources as well as the inventory levels fluctuate according to the situation in the various periods is still a challenging issue. Some available heuristics methods do not guarantee finding the globally optimal solution while some methods offer multi-period mixed integer nonlinear optimization models that can be solved only with tremendous difficulties. The present work focuses on the above problem subject to potential constraints on both the production as well as on the inventory; and an effective solution method is offered. First, the method considers the production part of the problem and transforms the original problem into a feasible structure. Then, the inventory levels are determined for the structure. Finally, based on the exploitation of the structure gained, a dynamic programming algorithm is proposed to give the final solution of the original problem. An example demonstrates the efficacy of the presented method. The present scientific contribution is dedicated to the 650th anniversary of the foundation of the University of Pécs, Hungary.

Vistas and prospects. Compositional tools in the design of the Transylvanian landscape FEKETE Albert*1 *Department
of Garden Art, Faculty of Landscape Architecture and Urbanism, Szent István University, Budapest, Hungary
Index Terms: landscape design, vista, prospect, visual connections, castle gardens
The present study’s main purpose is to presents the partial results of the survey of Transylvanian castle and manor gardens. The paper would like to highlight first of all the importance of the examination of the visual connections found during the garden history research as well as during the site survey of over 100 castle and manor gardens, and to confirm the landscape design role of sights. The analysis and evaluation of the landscape scaled visual links consists in the definition, examination and interpretation of two main types of visual connections in the landscape: - the vistas and axes, defined by outstanding visual elements (eye-catchers), - the prospects, defined by natural or designed landscape fragments or features The research was conducted by the Department of Garden Art within the Faculty of Landscape Architecture and Urbanism Budapest, Szent István University involving several experts and students in the work. The partial results confirm the compositional role of the visual connections in the landscape and garden design developed during the 18-19 centuries. The results prove the composed relations between gardens and the surrounding landscapes. The visual connections, as deliberate means of landscape design, were applied in Transylvanian landscape gardens as well in numerous places, and through their application a certain landscape fragment was determined for several decades or even centuries.

Opportunities for biodegradable straw-based thermal insulations FENYVESI Olivér* and CSANÁDY Dániel*1 *Department
of Construction Materials and Technologies, Budapest University of Technology and Economics, Budapest, Hungary
Index Terms:
Nowadays, thermal insulation of buildings becomes more and more important. The common answer to rising demands is the conscious design and installation of thicker thermal insulation, however, the environmental footprint of these artificial materials is significantly growing. Since biodegradable fibre thermal insulation has poor performance and high price today it is not a real alternative compared to EPS or rock wool products. Plant fibre based thermal insulation is dealt with before by many researchers too, but those researches mainly focused on the direct apply of straw bales in natural form. The anchorage of the bales is difficult and they only provide the needed thermal diffusivity values above large thickness. This makes the protection of insulation from the water more difficult because in most cases the overhang of the roof over the insulation is not enough. The tearing/splitting/schism of the ligament can cause another problem because of the slackening in the bale. The durable bond of the plaster is not ensured in case of natural straw material, its service life changes according to the average relative humidity. During our research the solution for all these problems are sought. Thereby natural insulations could be developed which could be a real and profitable alternative instead of commonly used thermal insulations. The first problem that the compressed plant fibres have to hold the geometrical parameters, were solved. The bale string tying was avoided, because it has a local like impact and there is a big risk of tearing and extension caused by the strings great creep value. So a sort of meshed ligament/tying or binding material were considered. During choosing the binder material it was also important to keep the eco-friendly nature of the insulation. In recent research phase straw-based insulation boards are investigated. At first step the optimal body density was examined. During the study specimens with various body density were investigated with constant binding and compressing method. As the main parameter thermal conductivity factor was measured. During the investigation of the thermal conductivity factor the specimens were measured in a completely dry state and these were covered with a vapour barrier EPS stocks. The thermal conductivity factor is also stable with a relatively small number of sensors and relatively short measuring time for all specimens. The body density of small specimens (150 mm x 150 mm x 50 mm) which was cut off from the large specimen boards (500 mm x 200 mm x 50 mm) are not completely smooth/even. This means that precision of production have to increase in the future, because it creates "more closely" correlative body density and thermal conductivity pairs. In addition, in case of specimens with lower density the inaccuracies of production are increasing. The recent result of research has shown, that thermal conductivity increases proportionally with increasing density. There is a local minimum point at the lower density range which contradicts the previous statement, the reason of this phenomenon is currently unknown. After theoretical considerations the conclusion is that the minimum point of the thermal conductivity curve is going to be found between 60 and 100 kg / m3 body density range in the future.

Minimizing plant material handling costs with linear programming FERENCZI Balázs*1 and NÉMETH Péter* *Széchenyi
István University, Győr, Hungary
Index Terms: operations research; material handling cost
The major requirements for the successful production and warehouse facility design and layout planning are the material handling activity transparency and low handling costs. This can be achieved by thorough planning of the plant hall in the early stage when the equipment positioning and material handling paths can be freely designed. Our goal is to find the optimum equipment placement in order to minimize total transport volume, taking into account the capacity of transport routes and gates. This can be regarded as a transportation problem. The bottlenecks are simulated in a way that the total cost model includes the probability and risk of forklift collisions. The optimization process will be performed with linear programming, where the collision risk is represented with a queuing model. This results in nonlinear elements in the model that has to be linearized.

Analysis of future changes in trends and scaling coefficients in shortterm rainfall in southwestern Slovakia FÖLDES, Gabriel*1 and KOHNOVÁ, Silvia* *Department
of Land and Water Resources Management, Faculty of Civil Engineering, Slovak University of Technology, Slovakia
Index Terms: short-term rainfall, rainfall total, trend analysis, scaling, design values
Extreme precipitation events with a short duration are increasingly occurring across Europe and have become one of the most frequently occurring natural hazards. During floods, high short-term rainfall rates causing major economic damages are observed. It is important to know climate changes in the future to plan for an adaptation in occurrence of damage according to diversity and changes in the climate. Therefore, it is important for the future to predict what changes will be in the rainfall intensity characteristics. The thesis focuses on the analysis of future changes in trends and design values of the intensity of shortterm rainfall in the area of Southwestern Slovakia. The analysis was performed for the climatic stations Bratislava, Gabčíkovo and Sereď. Interest area is located in the Danubian Lowland in the west of Slovakia. It lies between the rivers Váh on the East and the Danube on the West. Danubian lowland belongs to Slovakia´s warm area, it is the warmest district where is 50 or more summer days per year with a temperature above 25 ° C. The annual average temperature is about 9 to 11 ° C and it is also one of the driest regions of Slovakia with annual total precipitation less than 500 mm per year. Testing of rainfalls was performed for the durations 60, 120, 180, 240, 1440 minutes for past and future scenarios. Data used for the analysis were the actual measured values for the period of 1995 - 2009 provided by SHMU and data from regional climate models. 4 simulations were used in the work and each of them contained scenarios for the past and for the future. Data from the simulations were provided from the Czech Technical University in Prague. For all climatological stations, there were RCM scenarios: KNMIRACMO2, KNMI-RACMO22E, SHMI-RCA4 and MOHC-HadRM-3Q0. The analysis shows that from the real observations in the climatological stations Bratislava and Sereď there is a rising trends in the short-term rainfall totals, for the climatological station Gabčíkovo there is an decreasing trend in all periods. The simulations did not show a significant change in the trends, but the upward trend is assumed, but not significant. Scaling coefficients were derived for each station and for all simulations. The design values for rainfall totals and IDF lines were estimated by these scaling coefficients for a period of 10 and 100 years and for a duration of 120 until 1440 minutes. The highest scaling coefficient was set for the climatic stations Bratislava and Sereď in the HadRM-3Q0 simulation and for the climatic station Gabčíkovo was the highest coefficient in the KNMI-RACMO22E simulation. The assumption of an increase in the intensity of the rainfall is also noticeable at the design intensities of the rainfall totals, all the simulations exceed the scenarios for the future. Regarding to the predominantly increasing trends for the future and also the increasing intensity in design values for intensities of rainfall totals, it will be necessary to re-evaluate the design values for rainfall totals in assessing and designing water structures in the area.

Aerodynamic and energy optimized design of a NOÉ tech-lab university of Pecs The new project which is belonging to PTE MIK campus is designed by the faculty of architecture. The function would be a future oriented innovation center, which will be the ‘’tech-lab” center to carry out technical research projects of architecture and engineering students. In most common cases tech-lab which will be a center of physical activities and place for different experimental researches (complicated building ensembles with high standards) and education events. Integration high level of architectural quality and standards is usually a challenge in such design tasks, which can be further complicated through additional energy, climate and comfort problems. These design factors should be considered during the different planning phases. In frame work of supporting the new university tech-lab design a complex building physics simulation supported design process has been carried out in order to combine both functional and aesthetical design aspects with energy, comfort and climate issues. Computational fluid dynamics calculations (CFD) is also support the development. As a result of the simulation supported process an optimum compromise could be created that determines functional areas, materials, building body, windows’ shape and location, special organization as well as solving ventilation questions in the building with partly natural ventilation system or in other term passive ventilation strategies integrated with inevitable building services systems. The paper describes the different phases of design process with decision making simulation results.

Index Terms: K-mean algorithm, Empirical Bayesian, road crashes clustering, black spots, number of clusters
The planning of safety on road is always a difficult choice. Implementation of safety measures is costly, although all of it could have positive net benefits. Therefore, it is necessary to define priorities of high risk sites in order to utilize our limited resources as effectively as possible. The prevailing way of evaluating roads is in sections, so segmenting the road is considered the first and most important step for any successful evaluation model, and any weakness in this step could result in false positive or false negative in identifying the real dangerous location. In this paper we combine the benefit of Empirical Bayesian and K-mean clustering approaches for identifying of the high risk crash locations on the road. We firstly examine the effectiveness of k-mean clustering for identifying the homogeneous traffic accidents and classifying them into groups (clusters) based on its attributes and spatial distributions, which gave more flexibility in segmenting all road in different lengths based on their content and distribution of clustered crashes. Then, the safety performance function is identified for each different length cluster for identifying of the most dangerous locations based on the Excess Empirical Bayesian. However, integrated of both approaches resulted in more powerful technique that is able for identifying more dangerous crashes with almost similar cause of occurrence within an optimized segment length.

Index Terms: architecture, community, social engagement, Makovecz, SROI
Over the past 10 years, I’ve been in contact with Imre Makovecz’s architecture, both practicing at firms connected to his studio Makona Kft. and carrying on research activities on his thought and oeuvre as architect and public personality. Furthermore, it was through a direct observation and a direct contact with local communities living in villages where, during the last forty years, architectures designed by Imre Makovecz were established, that I could experience and verify the centrality of these buildings in community life. Such experiences and further considerations pushed me to continue the research on a more multidisciplinary level to investigate, evaluate and represent - through the use of SROI methodology - the social, cultural and economic impact generated by the work of Imre Makovecz and his collaborators, particularly within the faluházak project, carried out, during the 1970s and 1980s, for local communities, living in small villages disseminated all around Hungary. In particular, the research work focuses on the Cultural Houses and Village Centres, built in the Hungarian villages of Sárospatak (1972 – 1976), Bak (1985) and Kakasd (1986). Starting from the buildings of the cultural centres, studying and creating the appropriate social, architectural and environmental conditions, a process of awakening and of great modernity was born and continues today. The result of this research work may show us the effects and tangible evidences of a certain good practices and multidisciplinary approach in architecture, for the community.

Index Terms: medical school, green campus, research & education, student comfort
With the growth in international education and the increase in the number of students, the examination and development of university campuses at the University of Pécs have become necessary. A new building will be added to the Campus of the Medical School where it is required to place student and educational spaces, as well as research laboratories of international standards. It is a complex architectural task to create new modern spaces, establish relations with one another and also with the existing theoretical building block in the area. The large green space in the campus is closed, unused, but can be taken advantage of with the thoughtful placement of the new building. Student comfort can be improved significantly if the green surface is connected to the life of the area. During the design process, a complex, modern annex has been formulated in accordance with the above educational and research aspects.

Index Terms: medical simulation, simulation center, education, ‘spatial organization’, ‘planning methodology’, interior design architecture,
The social requirements of health education and the increased attention to the patient made it important to ‘practice’ on patients with the help of simulation training opportunities before the real situations in the last quarter of the 20th century. The legal and ethical aspects of the practical interventions on patients required the regulation of healthcare education. The Medi Skills Lab – Simulation Training Centre project started at the University of Pécs in 2012. The main task of the Laboratory is to develop the manual skills of medical students and doctors in graduate and postgraduate training. During the operation, it is necessary to hold compulsory, elective, optional courses and to realize the training needs of external partners. Education with simulation tools has different spatial organizational demands in connection with architecture. New planning methodological directions and designs are induced by the related functions that are separated in accordance to the technologies. The coherent relations between the functions can be reduced by user levels also in spatial organization.

Numerical dynamic stress analysis of air blast impact to the gas cylinder GRGIĆ, Ivan*1, IVANDIĆ, Željko* and KOZAK, Dražan* *Faculty
of Mechanical Engineering in Slavonski Brod, Croatia
Index Terms: dynamic stress analysis, gas cylinder, TNT, air blast
According to the Ordinance on liquefied petroleum gas (LPG), the storage of gas cylinders is usually carried out in the open space. Since this storage space is in most cases located next to the fuel supply station whereby the safety distance of the bottle storage to any possible permanent ignition source is 5 meters, there is always a potential risk of explosion. In order to show how the material of the gas cylinders behaves at the explosion, the impact of the air blast was simulated. The gas cylinder used for the analysis was a capacity of up to 10 kg. The 3D model of the gas cylinder was made in SolidWorks according to 10 HRN MZ2.510 regulative and numerical analysis was made in Abaqus and in Ls-Dyna. The initiation of the explosion is set at different distances from the gas cylinder starting from the 5 meters and closer, and also it is timedependent. For the explosion model, 10 kg, 50 kg and 100 kg of TNT charging were used.

Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary and Yantai University
Index Terms: Chinese traditional beliefs, contemporary, interior design
Chinese civilization has accumulated Chinese wisdom bit by bit, to gain full understanding of the origin of nature, the world. Chinese traditional beliefs influenced all aspects of Chinese people’s lives including interior design in the past. However, western cultures have affected Chinese civilization deeply nowadays. The purpose of this research is to discover that the connection between Chinese traditional beliefs and interior design still exists. Then, this project will explore which aspects of Chinese civilization can be used to develop Chinese contemporary interior design. Furthermore, it will uncover how to keep the balance between Chinese culture and western culture in contemporary interior design of China. These points are supported by three types of research methods: questionnaire, interview and photo ethnography. The answer to the question of whether or not the connection of Chinese traditional beliefs and interior design still exists is not only for China, but also for some other eastern countries. Each culture has its own unique features; each culture is an element to inspire designers. If the Chinese culture can be acceptable in contemporary interior design, some other cultures with similar situations to China can also take this article as an example. To find out the advantages of a local culture and to determine how to position the local culture and western culture in contemporary interior design will help the development of interior design in these countries.

Index Terms: arc protection, high voltage, live line maintenance
If the there is any possibility of the initiation of an electric arc in the vicinity of an electrician, the adequate steps have to be taken to ensure safety from the point of view of arc protection. One of the protection lines is the use of personal protective equipment. In low and medium voltage levels there are well defined methods for the selection of the proper protective clothes, face shield and gloves. This selection is based on an assessment about the magnitude of possible incident energy arising from the electric arc, which is suffered by the worker at the workplace. This assessment is also in practice in case of low and medium voltage works, but in case of high voltage (in Hungary it means 132 kV, 220 kV, 400 kV and 750 kV) the existing techniques could give quite different values in the same situation. These methodologies are based on various principles, empirical, semi-empirical and theoretical as well. The purpose of this article to show a new calculation model, which is able to calculate the incident energy in any places near an electric arc in case of high voltage, without the neglecting of the length and position of the electric arc. This method is developed especially for the electric transmission network above 35 kV and several meters of gap distances and it would be use to estimate the thermal load of a power line worker close an initiated electric arc during live-line maintenance by bare-hand method as well.

To understand Kosovo today, its urbanization trends and forms, it is necessary to know the historical geography of this territory and the state of art of remnants that shape its cultural (urban/rural) and natural landscape. Mapping and interpreting of these places opens the opportunity to understand the transitional nature of Kosovo’s urban reality today, and to inspire the comprehension of its future development within the European context. This will reveal the temporal and spatial consistency of Kosovo’s urban form and its consolidated geography. This logically leads to a brief history of the territory and a better understanding of modern-day Kosovo’s urban and spatial planning and future endeavours in the same context.

Connection between road network topology and accident data in cities HEGYI Pál*1 *Széchenyi
István University, Győr, Hungary
Index Terms: road network topology, continuity, connectivity, accident analysis
Drivers are not always able to detect the intersection in time. There are several reasons why the intersection can't be detected in time, for example the driver doesn't see the traffic signs or the connected road. The paper aims the investigation of the connection between accident data and the characteristics of the urban street network. Possible indicators of the road network topology are the ratio of the type of the junctions, the average distance between the junctions, and the connectivity and continuity of streets. Connectivity means how many road connect to the investigated street. Continuity is taken as the number of segments of the road. It is measured by the number of links. On the macro level the continuity rate can be determined in the selected areas. It is also worth considering continuity on each road of the network on the micro level. The results of the investigations are junctions where accidents are more likely to occur and therefor the attention of the drivers should be better drawn to the dangerous situation. They are visualized in diagrams, cartograms and by spatial distribution. The analysis was made using ESRI ArcGIS software.

Index Terms: heritage, memory, identity, colonial heritage, French Algeria
The concept of heritage in its basic definitions, arouses a feeling of belonging, throughout a shared memory; that relates nations to their past. However when this memory displays an unfortunate sequence of events, the reception and the acknowledgment of the heritage falls into the traps of controversial ideologies. The colonial phenomena, for many countries of the world remain a heavy subject to be treated. By virtue of the historical melancholy they experienced; the investigations on these delicate periods of history are frequently misconceived. That is the case of Algeria; a north African country that has been empowered by France from 1830 , until winning back its independence in 1962 , where the effects of this occupation are visibly reflected; in many aspects of the country, leaving the architecture stumbling between politics and creation. As a result, the architecture of the XIX and XX century in Algeria, introduces today a battlefield of polemic identities and ambiguous architectural emotions. The 132 years of the French existence, demonstrates, the military Genius, and the power of communicating political strategies, via Architectural productions. From the inherited Vainqueur styles, to a turning point towards the Protective era, France has celebrated its achievements in Algeria, by the destruction; the transfiguration, and the creation of many public and private monuments, making of the country; a disputable field of experiments and paradoxal understandings. French Algeria is considered as the vanishing Point for the interpretations of the patrimonial and constructive practices, furthermore; the examination of the colonial heritage continues to highlight the perplexity in the acts of preservation and conservation in modern Algeria. The main purpose of the research is to explore the complexities of the French pragmatics imposed in Algeria, within the colonial context. Setting the lights on the urban and the architectural oddities of the French experience, aims to give a reasonable methodological approach to the matter, regardless of the historical prejudgments in the vicinity of this subject. All in the intention of understanding the genesis of these buildings, in order to develop a coherent perspective on their historical evolution, and analysing their current state of conservation, to finally determine what could be the future of this vestiges of the Algerian history.

Mapping Hungarian cities based on social network of Wikipedia HONTI Gergely*1 and ABONYI János* *MTA-PE
Complex Systems Monitoring Research Group
Index Terms: Open Data, Linked Data, Semantic Web, Network science, Wikipedia
We created a bipartite graph of Hungarian people and cities with the aid of the Wikipedia and its semantical repository, DBPedia. DBpedia is used to identify the nodes of the graph, while internal hyperlink network of Wikipedia defines the edges. We identified people's role in connecting cities by the projection of the graph. The edge weights represent how many persons are in a relationship with both of the settlements connected by the nodes. We uncover the significance, the groupings, and the hierarchy of the cities by analysing the degree distribution, the centrality and the modularity of the network. Transitive node similarity enabled us to cluster and visualise the cities with dendrograms and multidimensional scaling. To demonstrate the applicability of the method we analysed the Hungarian Wikipedia. The results illustrate that the proposed city network forming methodology is useful in interpreting the cultural cohesion of the settlements. The results and the source code will be available on our homepage: www.abonyilab.com.

Automated plane segmentation from laser scanner data HONTI, Richard*1 *Slovak
University of Technology in Bratislava, Bratislava, Slovakia
Index Terms: terrestrial laser scanning, point cloud, plane segmentation, automated data processing, RANSAC
The technology of TLS (terrestrial laser scanning) currently is one of the most effective method of spatial measurement and spatial model creation of measured object. The result of measurement is a point cloud (irregular raster of measured points lying on the surface of the measured object), which represents a large amount of data. A point cloud documents the measured object with all his characteristic elements in high detail. Point cloud is a data source for 3D model creation. To increase the efficiency of 3D model creation, automation of these processes is desirable. Because of that, nowadays automatic processing of point clouds is very current issue. Segmentation, so classifying the points of the point cloud, falls under processing. By segmentation we can select geometric shapes from a point cloud. Automatic segmentation of point cloud relieves processing and shorts the time needed for processing, resp. for creating a 3D model. The paper shortly describes the methods and approaches for point cloud segmentation. For automated plane identification and plane segmentation from point clouds an algorithm based on RANSAC is proposed. The proposed algorithm was implemented to a standalone app., however MATLAB® runtime is needed for its execution. The proposed approach was tested by processing of point clouds, the results of the testing are described also.

Parallel city – social and cultural survival of Albanians during '90s HOXHA, Eliza*1 *Faculty
of Civil Engineering and Architecture, University of Prishtina, Prishtina, Kosovo
Index Terms: public space, culture, social movements, demonstrations, art of resistance, the right to the city
The abolition of Kosovo’s autonomy in 1989, for Albanians meant being expelled from jobs and schools, and media institutions (Television and Radio). Funded by the 3% tax of income mainly from Albanian Diaspora, Albanians created the education and health system in the private houses of Albanians. While the city turned to be a house for Serbs, for Albanians was the other way around – the house turned into a city. Everything what the center and the city in general provided for years for everyone, in the period of 1990s for Albanians it was dispersed into pieces and shrank into the private houses and locations in the edge areas of the city. A house became a school, a restaurant, a promotion place, an office, an art gallery, a hospital and a home at the same time. This reversal and merge of private and public, of closed and open, intimacy and transparency on one side affected the housing typology and on the other side the cultural mentality. The public space, when taken by Albanians, was only at times of demonstrate against government injustice. Deprived from media and information, Albanian families bought satellite antennas. One could have marked precisely which flats belonged to Albanians simply because these satellite antennas, looking as white circles, would hang in balconies. This way the city turned into a “garden of white mushrooms”. As 1990s mark also a period of vivid cultural and social movement, this paper asks: what was the relation of the city and space in relation to social and cultural movements? The paper will answer and discuss: 1. Transformation of public space by artistic manifestations - underground scene and private as public space 2. Art as revolt and protest 3. Aspects of social movements (cultural events) included in the two-hour Kosovo program transmitted through the Public Television of Albania (TVSH). 4. Spatial manifestation of parallelism in the city of Prishtina - dual city

Three simulations for decorative lighting of a bridge ISTÓK Róbert*1 and NAGY Máté Gábor* *
Power System Department, Kálmán Kandó Faculty of Electrical Engineering, Óbuda University, Budapest, Hungary
Index Terms:
This article presents three simulations for decorative lighting of the longest bridge (viaduct) in Hungary. The Kőrösi völgyhíd - Kőrösi Valley Bridge is located in one of the most famous Hungarian tourist region. The imposing dimension of the bridge is only visible in daylight but this aspect disappears in the night. The decorative lighting of the bridge could maintain this attraction through the nights. The position and the number of the chosen lamps give the differences between the three simulated situations. For all three simulations, the upcoming professional LED luminaries were used: Griven Powershine MK2 D, and Martin Professional Linear Cove 1200. In the first simulation, the linear lighting luminaries are placed on the side of the bridge that can be seen from the Blanton Lake shore. The rest of lamps are placed at the junction of the pillars and the bridge. All the lamps are down lighting. The main advantage of this layout is that the conception meets the Dark Sky Association regulations. That is mean we are lighting only that object what we have to and there is no lighting pollution up in the sky. The disadvantage of this conception is that the road, which passes under the bridge, is lighted so it can be annoying and frustrating for the drivers. In the second simulation the lamps are installed on the ground at the base of every pillar of the bridge. There are used seven lamps per pillar. The body of the bridge is highlighted with linear lamps too. The advantage of this concept is that all elements of the bridge are shown by light correctly. In the third simulation, only two lamps light the pillars and the linear lamps light the body of bridge. With this lighting solution the inside part of arcade are not lighted but the price of the decorating lighting system is lower so it is more cost efficacy. Simulation result when 7 lamps are placed on the ground and on the body of the bridge

Analysis of materials and local construction techniques in Nigeria JATAU, Raphael*1 *Faculty
of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: materials, construction technique
Local materials or materials easily accessible to man have been used in construction of buildings, and over time man has applied different construction techniques to save time, energy and resources. The aim of this research is to collect data and make analysis on the type of materials used, understand the construction process, identifying some challenges associated with these materials and construction techniques. Over time, a shift in the use of construction materials has occurred and what was once acceptable, is now discarded. Earth/adobe, was widely used in construction of buildings but over time it is replaced with concrete even though earth/adobe has good qualities. The aim of this research is to understand the reason for this gradual change in materials and the building techniques.

The reconstruction of military defence systems, (e.g. World War II defence lines) is generally based on military object identification and mapping. Since unexploded bombs can be still dangerous today, detecting bomb craters can be useful in creating hazard maps. The most significant problem is managing the large amount of relevant data. Therefore, there is a strong need for automatically select the potential areas and also automate the data processing. We developed automatic methods to reduce the areas of interest. In addition, our method can be applied in other tasks as well, for example in settlement detection.

Categorizing of inhaling behaviours using signal processing and data mining techniques KAHLOOT, Khalid*1, CSORBA Kristóf* and EKLER Péter* *Budapest
University of Technology and Economics, Budapest, Hungary
Index Terms: breathing, inhale behaviour, signal processing, convolution filtering, data mining, DBSCAN, SVD
The study of respiratory forms a major application and publication in the medical field. It characterizes the abnormalities in the breathing pattern. As a result, this may lead to detect undiagnosed diseases or select the appropriate treatment methods for those diseases based on this characterization. A medical team gathered data from randomly selected recruits. A huge dataset was prepared, which capture the volume and velocity of the breathed air from the target recruits. In this paper, we present the results of carrying out some of the signal processing, dimension reduction, and data mining techniques over this dataset. In particular, convolution filter, SVD and DBSCAN were applied. We managed to categorize of inhaling behaviours into nine groups but with high noise. Some of the groups are big enough and distinguishable. Results will be considered by the medical team for choosing the appropriate inhaler out of five types of inhalers appropriate for each group.

The area of boiling heat transfer and multiphase flow is extremely huge and it has been a subject of numerous investigations in the past decades. Heat transfer fluids such as water, ethylene glycol and mineral oil play a vital role in many industrial applications such as cooling systems, power generation, chemical industry, etc. The heat transfer performance of these fluids limited by their low thermal conductivities. However, Advancement in nanotechnology has allowed producing solid particles in Nano-scale (1-100 nm) that could disperse in liquid and such fluids termed nanofluid. The aim of this investigation is to study the forced convection flow boiling heat transfer of water and nanofluids inside vertical channel. Various nanoparticles dispersing in water with different dilute volume concentration and particle size will be used. Moreover, Laminar and turbulent flow with range of Reynolds number (400-50000) will be studied to show the effect of mass flux on the performance of heat transfer. In addition, important operation parameters such as heat flux, sub-cooled inlet temperature and pressure system will be considered. A numerical simulation based on computational fluid dynamics (CFD) software ANSYS Fluent 17.2 with single-phase and multiphase models will also be employed. The expected results will be somewhat challenging because there are a conflicting results in literature regards this topic, especially for prediction the heat transfer coefficient for flow boiling of nanofluid.

Effect of air induced flow on mixing in biological wastewater treatment KARCHES Tamás*1 and PAPP Tamás* *National
University of Public Service, Institute of Water Supply and Environmental Engineering, Budapest, Hungary
Index Terms: aerobic mixing, air induced flow, wastewater treatment
Homogenisation of the suspended solid in wastewater treatment applying activated sludge is a key factor in utilization of the aerobic reactors effectively. In such reactors mixing is provided by mechanical mixers and aeration simultaneously. Fine bubbles with diameter of 1 to 3 mm are preferred to enhance the oxygen transport to liquid phase. As the bubble rises it induces a flow in the liquid phase which helps in the mixing. In this research the flow pattern was analysed at different diffuser setups in basins with various length/width ratio in order to determine the effect of aeration. Residence time distribution analysis helped us to improve reactor models by calculation of the convection/diffusion ratio at each scenario. As an outcome of the research, proper reactor model parametrization is achieved, which could be used in future investigation in e.g. biokinetic modelling.

Correspondences between the geometrical proportions of the formwork and concrete composition in the case of fair-faced concrete elements - Research methodology KÁROLYFI Kitti*1 and PAPP Ferenc* *Széchenyi
István University, Győr, Hungary
Index Terms: fair-faced concrete, concrete composition, geometrical proportions, packing density, concrete rheology
Designing a concrete is first of all a packing problem. There are some existing methods (Compressible Packing Model, approximation of an „ideal curve”) to build a dense polydisperse mix, but only mixtures placed in a formwork having large dimensions (as compared with the maximum size of the particles) were considered in these models. The main hypothesis of this research is that the packing density and so the cement paste demand will be different with a given grading span and compaction method, but with different geometrical proportions of the formwork. When the packing density by different geometries is known, the rheological properties and thereby the placeability of the mixture can be predicted with the above-mentioned models. The goal of this research is to work out a method, with which the demand of saturation degree of cement paste can be obtained depending on the geometrical proportions of the formwork in order to reach the highest surface-quality.

Long-term monitoring of a long span railway bridge KAŠPÁREK, Jiří*1 *Czech
Technical University in Prague, Prague, Czech Republic
Index Terms: steel, arch, skew, bridge, steering bar, long-term monitoring, evaluation, track, interaction
The article describes an evaluation of a long-term monitoring of a railway bridge. The evaluation is focused on track stiffness and track-bridge interaction according to temperature changes and deterioration of the bridge. New railway steel bridge called „Oskar“ is located on the line Hohenau(A)-Přerov(CZ) near Břeclav. Main structure is a network arch supporting main girder with span 97,5 m and an extraordinary skew angle 41°. It is divided into 2 structures, each transferring 1 track. The bridge deck is orthotropic with cross beams and longitudinal stiffeners. Due to long span, it was necessary to equip the bridge with Meyer-Wunstorf (MW) steering bar, which reduces the stresses in the track caused by the track-bridge interaction. A network arch bridge with enormous skewness and steering bar is unique not only in Czech Republic but also in the whole Europe. To understand the track-bridge interaction on this bridge, an extensive continuous monitoring lasting 4 years was started in December 2015. It is possible to obtain various data from this monitoring, such as stresses in the track, temperature of the deck, horizontal displacement of the track and the bridge.

Index Terms: architecture, CFD, vinery, passive, ventilation
The planning of a ventilation, during the design of our public and commercial buildings, is always a difficult challenge. The aspects of energetics, comfort, function and environment are had to be considered. Villány is a town nearby Pécs as well as the center of one of the high-class wine-growing region in Hungary. The research group of the Energia Design Building Technology (part of the University of Pécs) was charged with the designing of a new vinery building nearby Villány. Since the research group is dedicated to the pioneer and green solutions, therefore, a passive ventilation system was needed for the cellars and the manufactory within the vinery, which is modern, comfortable, economical and environmentally-friendly at the same time. How was the way from the conceptual form to the final building and the passive ventilation system included? How could the ANSYS® Fluent software – Computer Fluid Dynamic (CFD) – support an architect during the process of the design? How the results from the aerodynamics could be really useful for the creative mind, and not hold it back, but help to go on? This questions and other will be answered in the presentation.

Index Terms: railway safety, safety management systems (SMS), safety-relevant application conditions (SAC)
As safety is one of the key point of today's and future railway success, we have to take care about it beside the functional and technical improvements. We discuss the importance of the proper handling of safety relevant information (safety-relevant application conditions – SACs) in a railway network operation, and then shortly review the history of the way we think about safety, why we use Safety Management Systems in the field of railways, what phases of a Safety Management Systems can be distinguished and emphasize the importance of the documentation of safety information. As the development, integration and operation of the railway subsystems and components involve many parties, it is important to deal with the organizational or rule based aspects of safety of the technical systems. We point out who handles the safety information (operating organization or the safety organization), and what kind of information a railway authority has to get from its suppliers and what kinds of information are generated within it. We will see there is a defined lifecycle model of railway systems with phases and main responsibilities for parties and introduce certain interfaces between these parties where safety relevant information flows from one party to another. We define what a Safety Application Condition (SAC) is, and what are the main categories of it for the design, construct and operation of a railway, and also define what tasks of a safety organization are related to SAC requirements. Beside the theoretical background, we present some possible use cases of a SAC database, and answer some questions about the importance of rulebook reviews, periodical supervision, and accident and incident data collection, the deduction of vehicle requirements based on infrastructure needs or safety assessment of a modification in the rail infrastructure. After the theoretical studies we examine the network models and their applicability: how a railway system could be defined based on its interrelated components or what are the necessary models and what are the relationships between them to achieve the advantages of the previously defined use cases. (Naturally) there are network models for railway networks to support various operational, engineering, simulation, etc. purposes. We talk about how these models could be biased towards a register of network element localized SAC requirements, and how a supplier could deliver SAC requirements to help infrastructure managers or railway undertakings to get the proper, full set of it.

Index Terms: computer vision; image projections; radon transform; object matching; supervised machine learning; convolutional neural networks
Precise object detection and labelling are crucial in Computer Vision applications: it is mostly based on a matching method, which results in a single value of similarity. This method could be a comparison of the template image with the input, or it could be based on higher level methods where certain keypoints, features are extracted from a set of template images, and these key elements are sought on the reference. The quality of the input images is crucial: for example, if the weather conditions are not favourable, the taken pictures could contain only minimal colour information, and the lack of natural light can cause low image quality. The objective of matching such images is difficult, especially if all instances of the objects of interest are very similar. In this case, low-level features should be analysed, such as image projections, for example, the Radon transform of the objects visual representation could be compared. A different approach to the decision, nowadays popular Machine Learning methods could be applied: if there are sufficient training samples, a classificator based on these data could be created using supervised training. Complex Neural Networks, with a large number of inputs, layers, nodes can be effectively trained using dedicated multi-processor devices, or advanced graphical accelerators. These ""deep learning"" based solutions and the applications of Deep Convolutional Neural Networks are highly researched.

An agent based model of tumour growth on a three-dimensional regular lattice KISS Dániel*1 and LOVRICS Anna† *Doctoral
School of Applied Informatics and Applied Mathematics, Óbuda University, Budapest, Hungary †Institute of Enzymology, Research Centre for Natural Sciences, Hungarian Academy of Sciences, Hungary
Index Terms: agent based model; solid tumour growth; three-dimensional lattice model; molecular diffusion
Detectable solid tumours consist billions of cells and their typical diameter are in the magnitude of millimetres. Simulating the evolution of such cell conglomerates is computationally challenging, especially if we wish to follow the lifetime of each cells one by one. A possible simplification method is to ignore the sizes and the exact positions of cells and assign them to the points of a lattice. We created an computational three-dimensional lattice model where every node can represent a cell agent or some empty space (like extracellular matrix). Concentrations of chemical compounds in the surrounding environment are represented by numeric properties of the nodes and they obey mass-transfer laws such as decay and diffusion. Cell agents are able to take up and also secrete some of the chemical compounds which affect their fate, for instance the presence of a high-concentration chemotherapeutic drug can alter the probability of cell death or replication, while other drugs may change the motility of the agent. Parameters such as the net growth rate of the tumour observed in vitro are used to estimate the properties of agents. Preliminary results showed that the current implementation of our model is able to simulate up to ten millions of agents in reasonable computational time.

Index Terms: power electronics, hil, p-hil, hardware-in-the-loop, simulation, real-time, power converter
Nowadays power converters are gaining more and more importance due to the increasing demand of energy efficient solutions in industrial applications, renewable energy sources and electrical transportation. To satisfy this new demand, more and more efficient -- both in time and energy -- development methods need to be implemented. Offline simulations can be used to test some of the control algorithms and concepts, but they will fail when the real time system behaviour needs to be tested. HIL simulators are implemented to solve this problem, by providing a transparent real time simulation environment to the control hardware. With this approach, the control hardware can be tested and the algorithms can be perfected, the only remaining restriction is the lack of the test of the power level circuits, which are the core components of every power electronics device. This is the problem which can be solved with Power-level HIL simulation. P-HIL simulation provides an environment to the complete power electronics hardware to test the product with various type of loads, or simulates the power source as well. The system will not contain any moving part, therefore the reliability can be much higher, and work with this kind of systems can be also safer. This paper is going to summarize and introduce the current state of the art P-HIL systems and technologies.

Hungary has been home of lot of nations from the beginning of its history. That’s why the buildings of the country are made and used by several nations and ethnic groups. In our research we would like to find out how to become a building which is made by a conquering empire determinative element of our national and local identity. The purpose of the research and our personal motivation is to collect, measure and find the options of the recycling of the Islamic-Turkish memories. Beside the geometric measures the members of the group are researching in the archives as well. Thanks to this we would like to create a systematic publication of the Turkish architectural memories in Pécs (and after that in all of Hungary). To document is an important project in my opinion but not enough. Many times today’s people only run along these important buildings/remains without that they realized how invaluable monuments are around them. Who look for these memories directly will not find them easily pretty often. That’s why we feel necessary to highlight these city points, to get them closer to the youth with the SMART technologies. The research has four levels. First level: Turkish architectural monuments in Pécs; second level: create case study; third level: recycle these monuments; fourth level: using the SMART technologies. We want to show for the youth that these monuments are very important for our culture.

Therefore it is no wonder that the city’s sacred architecture represents the diversity of residents. In different historical periods certain buildings belonged to different cultures and served several other functions than their original purpose. Today’s Pécs has been significantly affected by the blending of cultures which can be recognized both in people and in built environment.

Experimental verification of real behaviour of bridge structures using proof-load test KOTEŠ, Peter*, VARVUŠ, Martin*1 and BUJŇÁK, Ján* *
Civil Engineering Faculty, University of Zilina, Zilina, Slovakia
Index Terms: bridge, proof-load test, real behaviour, truck, deflection, verification
The aim of the paper is to point out the inevitability of proof-load tests for the real and correct behaviour of bridge structures and maximum allowable deformations in SLS. We point the most consequence on resistance, reliability, durability and lifetime of the bridge structures. Using the proof-load tests for new bridges is prescribed by Slovak standard STN 73 6209. The proof-load tests have to be carried out to detect defects prior to putting the bridge into operation. Basically, it is an experimental verification of the real behaviour of bridge structure in order to detect the visible and hidden defects that could limit or disable the operation of the bridge.

Design Challenges of Educational Buildings for Disadvantaged Communities KOVÁCS Péter*1, SÓDAR Norbert* and KÓSA Balázs* *Breuer
Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: architecture, educational institutions, multiculturalism, minorities
Educational buildings, especially those geared towards minorities and organizations aimed at supporting them, present a special set of challenges for the architect. The resulting design needs to take into account not only the social needs of student, and the criteria raised by the educational methods and curricula of the institution, but also the broader social context of such developments. In addition, projects of this nature often suffer from insufficient funding, thus requiring affordable yet sustainable solutions. One example of architecture dealing with these issues is a design discussed in this case study - a building that would serve as a dormitory for underprivileged students in Miksolc, Hungary. The aim of the presentation is to elaborate on the challenges faced during the design, the steps taken to meet them, and the proposed solution.

Index Terms: Tettye, Malomséd, mill, building heritage, rehabilitation
Malomséd, Malomszeg-vicus, Malomszeg: in the Middle Ages, as such names were mentioned the territory of the valley of the Tettye stream. The karst springs have spawned the water-intensive industries and mills, becoming the cradle of the industry of Pécs. However, with the industrial development and the establishment of the water network of the city, the water mills were dismantled and its buildings were demolished. The exception is the Nürnberger mill, which was used as a residential building from the 20th century. The aim of the research is to find out about the historical transformation of the area and to chart the changes of the building, and then to create an environment appropriate to the living conditions of the age, while maintaining the character and architectural heritage of the building.

Losses in laminated media KUCZMANN Miklós*1 *Széchenyi
István University, Győr, Hungary
Index Terms: eddy currents, losses, finite element method
The paper aims at developing a finite element based computational technique to take the laminated nature of three dimensional iron cores into account. The method has two steps. In the first step, the laminated material is assumed to have an anisotropic conductivity with zero value in the direction normal to the laminations. In the second step, the eddy currents inside the laminations are computed by solving the electromagnetic field individually in each sheet, and the boundary conditions are taken from the three-dimensional field distribution determined in the first step. A simple arrangement (a laminated cube is placed inside a coil) is shown. Results of the proposed method are compared with a reference solution. The presentation will focus on linear material and potential formulations, the full paper will present nonlinearity with vector hysteresis.

Design of soil erosion control measures and assessment of their effect on peak flows reduction LABAT, Marija Mihaela*1 and HLAVČOVÁ, Kamila* *Slovak
University of Technology, Slovakia
Index Terms: erosion control, soil erosion by water, USLE, USLE2D, CN method
Erosion is a natural continual process of soil sphere transformation, that can’t be stopped, only limited. The process is caused by erosion factors (wind, water, ice, snow, humans etc.). The result is a detachment of soil particles from earth surface, which is transported by the kinetic energy of erosion agents and deposited in slope depressions or valley basins. One of the major threats on the territory of the Slovak Republic is water erosion, caused by the impact of rain drops on the soil surface. This can lead to creation of surface runoff or even to concentrated drainage in riverbeds. Water erosion affects large agricultural areas, transports nutrients and organic matter, causes degradation of the fertile soil layer and the breakdown of soil structure. Erosion can also lead to environmental problems, through sedimentation and increased flooding, therefore, the main aim of this work is design of soil erosion measures to prevent soil loss and assessment of their effect on a peak flow reduction. The examined region was the river basin of Halúzníkov potok in Vrbovce municipality, which is administratively incorporated into the Myjava district and the Trenčín region. The area of watershed to the firth of Teplica is 9.13 km2. At first, applying methods of USLE and USLE 2D, the average annual rate of soil loss on fields used as agricultural land was calculated. The calculations were done by geographical information system that enabled results to be in both graphical and table forms. Since the average annual rate of soil loss was more than an accepted value, strip cropping was proposed as the soil loss measure on parcels where slope doesn’t reach value greater than 15%. This agronomic measure consists in rotation of strips with small protectioneffective crops and strips with protection-effective crops, like fodder crops. These strips are designed to be same wide to allow reversed usage and perpendicular to the contour lines, to prevent transportation of soil by runoff. On parcels with slopes greater than 15 %, grassing was recommended because measures didn’t ensure enough soil loss protection. Applying method of CN curves, an effect of erosion measures to reduce peak flow was assessed. The aim of calculations was to compare values of designed peak flow QN, for current situation in the river basin, with designed peak flow QN, after measures in river basin are applied, for a repeat period of 10, 20, 50 and 100 years. As a result, Q10 is reduced by 14.3 % if originally parcels were used fallow land, by 6.7 % if originally parcels were used for broad leaved crops and by 1.6 % if originally parcels were used for close up crops. Q20 is reduced by 13.8 % if originally parcels were fallow land, by 6.5 % if originally parcels were used for broad leaved crops and by 1.5% if originally parcels were used for close up crops. Q50 is reduced by 13.3 % if originally parcels were fallow land, by 6.2 % if originally parcels were used for broad leaved crops and by 1.5% if originally parcels were used for close up crops. The smallest effect of measures is on peek flow Q100 , which is reduced only by 12.9 % if originally parcels were fallow land, by 6.1 % if originally parcels were used for broad leaved crops and by 1.4% if originally parcels were used for close up crops. Results imply that recommended erosion measures also have effect on reduction of peak flows. The best impact was achieved for a design period of 10 years, with lower design period, the effect of erosion measures on the reduction of the peak flow is decreased.

Examination of Bimoment Transmission Through Joints of Steel Frames LÁSZLÓ Gabriella*1 and PAPP Ferenc* *Széchenyi
István University, Győr, Hungary
Index Terms: steel, frame structures, joints, frame stability, warping transmission
Designing a steel structure one of the most important problems is the global stability, especially in case of members with open I and H steel profiles. Steel frames are often built from these members which are susceptible for out-of-plane deformation with warping. Developing an adequate method for check of frame stability resistance has been becoming an important question. The recently evolved design methods based on 3D analysis are validated for isolated beam elements but not for frames. The joint behaviour affects significantly on the global out-of-plane structural behaviour of frames. For these design methods it is important to use 3D design software which transmits the warping stress through the joint properly. This paper summarizes these recent methods and their problems in case of steel frame design. The recent researches and results on warping transmission through joints are discussed.

Index Terms: modelling, model-checking, Petri net, automata, safety critical, interlocking
The use of formal modelling has seen an increasing interest in the development of safety-critical, embedded microcomputer-controlled railway interlocking systems, due to its ability to specify the behaviour using mathematically precise logical rules. Our research goal is to prepare a specification environment, which supports the developer of the railway interlocking systems in the creation of the formal specification, and at the same time hides the inherent mathematical–computer science background knowledge. We present a case study with the aim to describe a possible process to formalize a domain specification, and we show the available further utilization possibilities (e.g. verification methods).

Visibility studies at roundabouts entries MAGYARI Zsófia*1 *Széchenyi
István University, Győr, Hungary
Index Terms: road safety, visibility at roundabouts, site distance triangle, angle of view
Background Most of the accidents in roundabouts occur at the entries. One of significant reasons of that is poor visibility. Objectives The visibility depends on the geometry of the roundabout, objects which may block the view and traffic as well. My aim is to investigate the effects of these factors and to combine them at roundabout entries. Methods To analyse this questions two roundabouts were measured by laser scanner. The sites were modelled with three dimensional point clouds and two vehicular situations. In the first situation is the car driver stops before entering the roundabout, in the second aspect when he does not necessary stops to pass in. The fields of view were studied from the viewpoint heights of cars and lorries as well. Results To compare the results the angles of view were defined. The full angle of view and the hidden angles obstructed by objects were measured in the point cloud model. These angles are able to characterize any kind of terrain feature and calculate the ratio of clear or hidden part of angle of view. Knowing the required full angle of view we can determine, how much have drivers move their heads to the left and to the right to cover the whole field of view, which is an important factor of safety and comfort.

Impact of management decisions based on managerial competencies and skills developed through BIM technology on results of construction enterprises MANDIČÁK, Tomáš*1, MESÁROŠ, Peter* and TKÁČ, Matúš* *Faculty
of Civil Engineering, Technical University of Košice, Slovakia
Index Terms: BIM technology, managerial competencies, impact of BIM, construction enterprises
Current times require decision-making based on relevant information and experience of managers in every field. Information and communication technologies are a good tool for collection and use of relevant information for decision-making, generally. Management of construction enterprises also requires experience or managerial competencies. To achieve successful results of construction enterprises and projects, for example as cost reducing, increasing revenues, shortening construction time, both are necessary. BIM is increasingly getting into the awareness in the construction industry. BIM is the process of creating and managing data about the building during its life cycle. BIM has become a part of management tools in modern construction enterprises. BIM can represent technology for developing of managerial skills for managers. Based on these facts, there are several questions. What is the use level of BIM in construction enterprise? What is impact of BIM on project and enterprise results? How do this tool influence on management decisions and the development of managerial competencies? Research focuses on issue of impact of management decisions on managerial competencies and skills developed through BIM technology on results of construction enterprises. Main aim of research is analysing and quantifying impact of management decisions on managerial competencies developed through BIM on results of construction enterprises in Slovakia. Cost reducing, increasing of revenues and shortening construction time are main monitored enterprise and project results. Research hypotheses are based on the assumption that BIM technology has a positive impact on development of managerial competencies and skills, manager’s right decisions also. This can lead to lower costs, increase revenue and reduce the time of construction. This research also tries to quantify this impact.

of Sanitary and Environmental Engineering, Faculty of Civil Engineering, Slovak University of Technology, Slovakia
Index Terms: bromates, drinking eater, removal, adsorption
In analysis of drinking water are frequently occurring ""new"" elements, which cause a change in water quality. Among these elements bromates are included. Bromates (BrO3-) are substances that aren´t commonly determination in drinking water, they are usually found in mineral water and seawater. Their occurrence in drinking water dependents from the present of bromine ions in water and water treatment process by ozone disinfection. Bromates are characterized by their specific properties, for which they are classified as dangerous substance that can cause a serious health problems. Currently there are several technological processes for removal of bromates from drinking water. Adsorption is one of the methods which we have use in this work with various sorbent materials: Active carbon, Bayoxide E33, GEH, Kemira CFH 12 a CFH 18, Activated Alumina and Zeolit.

Using numerical modelling error analysis methods to determine changes in a watershed MÁTYÁS Kevin*1 and BENE Katalin* *Széchenyi
István University, Győr, Hungary
Index Terms: watershed hydrology, numerical modelling, error analysis, impacts on watershed
Understanding the hydrological variability in the Kisalföld region is important to support long-term decisions for sustainable water management. Hydrological variability can be evaluated through annual, seasonal or daily flow analysis. The paper consists of two parts: (1) develop continuous rainfall-runoff models for four watershed in the Kisalföld region using the HEC-HMS software, and (2) identify variation in runoff characteristics due to climatic factors or changes in watershed using numerical error analysis. The model was calibrated for the 2008-2015 time period and validated between 2000 and 2015. The results were evaluated using graphical and statistical measures. Two statistical methods were selected for evaluation; Nash and Sutcliffe model efficiency (NSE) and Kling-Gupta Efficiency (KGE). The statistical measures were assessed not only at the final time step, but during the calibration and validation period as well. After the initial adjustment the well calibrated model became stable and very small changes were detected during the observation period. In 2010, at each model a significant jump occurred in the error analysis, additionally one of the watershed behaved very differently during validation from the calibration period. The jumps were caused by climatic factors, large rainfall and consecutive flood had a significant impact on the watersheds. It was determined that during the validation period one of the watershed was rehabilitated; the main channel was reconstructed with a new concrete lining close to the runoff observation station. By observing the continuous statistical measurements, changes can be detected in either meteorological, watershed characteristics or can indicate some kind of measurement error.

Composite truss beams: experimental and theoretical research MICHALEK, Peter*1, BUJNAK, Jan* *Faculty
of Civil Engineering, University of Zilina, Slovakia
Index Terms: BIM technology, managerial competencies, impact of BIM, construction enterprises
The design specifications of composite trusses are only partially included in the European standards. However this construction system can be considered as one of the most economical for building and bridge structures. In general, the composite trusses can be used for greater spans up to the 30 m, which allows better use of internal space without restricting columns. They are appropriate also to meet the requirements for building height limitation, the need to run complex electrical, heating, ventilating, and communication systems. To create the interaction between steel and concrete, it is necessary to prevent the relative slip at the steel and concrete interface using the shear connectors. But the local effects of a concentrated longitudinal force and the distribution of the shear force between steel section and concrete slab, as special task, should be appropriately examined. The finite element analyses can be used to investigate numerically this structural system behaviour, exploiting several computer procedures. The experimental research has tested these procedures. The outputs of this study would be presented in the eventual paper.

Software development for Internet browsing using Java language MILOIU, Andrei* and LUNGOCI, Carmen*1 *Faculty
of Electrical Engineering and Computer Science, Transilvania University, Brasov, Romania
Index Terms: web browser, Java, database There are many tools to browse the Internet, but at many of them the important functions lack, like privacy, data security (for bookmarks and history). However, they could be very complicated for simple users and even for advanced ones, making things hard to realize. This work deals with the development of software that creates a browser called Andrew’s Browser, which tries to respond to all of these problems. It wants to help simple users and companies giving them a useful, rapid and simple tool to navigate on the Internet, without useless functions. In this way, the browsing is made faster and easier. The project is divided in two parts: the browser itself and its website. The first part helps to surf the Internet (like all the other browsers), but with some differences. The history and the bookmarks are stored in a MySQL database (and not in .xml files), which help the user to access them in the browser, but also from the website. In this way, all the user information remains in a safe place without the risk of losing them due to a virus or damage. For the first part the following packages have been used in order to develop and write the program: SWT, a package developed by IBM for the main frame; Swing, for the other frames launched by the main frame; SQL, for connecting the MySQL databases; java.io.* and java.util.*, for working with files; AWT, for the actions of the buttons (events); Javascript, for events; HTML, for the content of the Help. The second part is presenting the browser and from here it can be downloaded. Also, the user can view and manage the history and the bookmarks. For that, the following programming languages have been used, in order to design the website: HTML, for the content of the webpage; JavaScript, for filling fields verification; CSS3, for the interface; PHP, for managing the database; jQuery, for working with MySQL data tables; MySQL, for managing all the created databases. Figure 1 presents the home page of the browser official website and its source code. The complexity of the software developed by the authors ensures the efficiency of the created browser, the rapidity, the easiness in installation (does not occupy too much space), the portability, a very friendly interface and a shorter response time, comparing to traditional browsers. However, from this software are missing some features, like: the possibility to update the browser, a native function to make screenshots to webpage (comparing with many traditional browsers), a user custom database (which can be accessed and modified by using an account and a password) and the automatic encryption of the data of the users.

Details that influence the interpretation of architectural form and structure MOLNÁR Tamás *1 *
Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: architectural form, detail, structure, view
The understanding of the architectural space is based on the human body and senses. Probably the most important sense is the eye. The question is how far a spectator can or should believe in that what can be seen through the eyes. Already the ancient Greeks used special detail solutions to construct unique buildings that seem to be perfect. In many cases the opposite happened in the history of architecture. A certain building could have a look that it is not special but surely not perfect although the details made it unique. The understanding of the architectural concept or the analysis of certain details and structural solutions can clarify how far the view seen through the eyes is the reality. Aim of this presentation is to enlighten certain architectural solutions that were used during the modern history of architecture to design unique buildings with a possibly perfect form or a real structural specialty.

The importance of green rating systems in Hungarian road design NÁDASI Réka*1 and TÓTH Csaba* *Budapest
University of Technology and Economics, Budapest, Hungary
Index Terms: Sustainability, Life Cycle Assessment, Rating Systems
Sustainable development and environmental awareness is increasingly attracting substantial attention in whole Europe. As sustainability has great importance in every kind of engineering, it is also important to incorporate a similar approach into the road design and construction. Therefore, in the case of road network development, environmental issues are drawn into the focus. To measure the environmental impacts during the lifetime of the roads, Life Cycle Assessment (LCA) techniques appeared. Numerous methods and software were developed during the years to show the greatness and importance of the impacts in each stage. The study shows the operation and the structure of the SimaPro program which is one of the most widely used software for LCA studies. The question may also arise which stage of the workflow of a new road could possess the greatest significance. Studies indicate that the impact can be considerably reduced in the planning and the design stages if sustainability is evaluated. For this reason, stakeholders have also a big influence on the success of the road network in the aspects of environmental issues. To measure the success of sustainability and help to the decision makers, a system of objective measurement is inevitable. In the example of well-known and worldwide-spared used green rating systems for buildings (e.g. LEED – Leadership in Energy and Environmental Design), it has also vast significance to introduce it to the infrastructure sector. Nowadays, a number of rating systems exist like GreenroadsTM, BE2ST-In-HighwaysTM, CEEQUAL or the EnvisionTM. These systems are used not only the USA, France, Germany and other great powers but also countries such as Iran or South Korea. As a consequence, employing a rating system such as the formerly mentioned in Hungary has great importance for the reason to promote the sustainable development. It is also generally accepted that the incorporation of sustainability in roadway design has difficulties, barriers and limitations. It could cause additional fees, additional complications as well as extra man-hour spending. The study also discuss the forthcoming tasks to introduce this system.

Index Terms: Web server, Web framework, Performance analysis, Benchmark, Comparison
In the recent years many new web technologies have appeared on the market and in terms of speed and reliability, they are already comparable to conventional thick client solutions. A new competitor on the market, ASP.NET Core supersedes the previously Windows-only server-side framework, is now completely open source and platform-independent. The software vendor also started to develop a new web server solution called Kestrel. In this paper we are the first in the world to present the results of three different benchmark scenarios measured on two different operating systems comparing them to a concurrent technology, Node.js.

Finding the representant element in a cluster using correlation clustering NAGY Dávid*1, MIHÁLYDEÁK Tamás* and ASZTALOS László* *Faculty
of Informatics, University of Debrecen, Debrecen, Hungary
Index Terms: correlation clustering
Finding the representing element in a cluster using correlation clustering One of the main tools of data mining is cluster analysis. Here the set of objects are grouped in such a way, that the objects in the same group are more similar to each other than to those which are in other groups. Usually the similarity and dissimilarity are based on the attribute values describing the objects. Although there are some cases, when the objects cannot be described by numbers, but we can still say something about their similarity or dissimilarity. Think of the humans for example. It is hard to detail someone’s looks by a number, but we still make statements whether two persons are similar to each other or not. Of course these opinions are dependent on the persons. Some can treat two random persons as similar, while others treat them dissimilar. If we want to formulate the similarity and dissimilarity by using mathematics, we need a tolerance relation. If this relation holds for two objects, we can say that they are similar. If this relation does not hold, we say that they are dissimilar. Of course each object is similar to itself, so the relation is reflexive, and it is easy to show, that it also needs to be symmetric. But we cannot go any further, e.g. the transitivity does not hold necessarily. Correlation clustering is a clustering method based on a tolerance relation. The clusters we get from correlation clustering contain the most similar entities. In many cases it can be interesting to find the member which is the most similar to the other ones. This member can be treated as the representing member because it can represent the whole group. This can be very helpful in solving some problems. A very simple one is the following: If we would like to convince some people that our product is useful then it is easier to convince only the group’s leader and then the rest will follow. This could save much time because we do not have to deal with everyone only one person. In this work we are showing a technique by which we can determine a representing member of a cluster. For testing the method we have developed a software which also helps us visualize the problem.

Investigation of glued insulated rail joints with special Fibre-Glass Reinforced Plastic fishplates NÉMETH Attila*1 and FISCHER Szabolcs* *Department
of Transport Infrastructure, Faculty of Architecture, Civil Engineering and Transport Sciences, Széchenyi István University, Győr, Hungary
Index Terms: glued insulated rail joint, GIRJ, fibre-glass reinforced fishplate, polymer composite plastic material, laboratory test
Introduction In this paper the authors partially summarize the results of a research on glued insulated rail joints (GIRJs) with fibre-glass reinforced plastic fishplates (brand: Apatech) related to own executed laboratory tests [2], [4]. The goal of the research is to investigate the application of this new type of glued insulated rail joint where the fishplates are manufactured at high pressure, regulated temperature, glass-fibre reinforced polymer composite plastic material. The usage of this kind of GIRJs is able to eliminate the electric fishplate circuit and early fatigue deflection and it can ensure the isolation of rails’ ends from each other by aspect of electric conductivity. The advantages of such GIRJs are the fact that the expensive replacements of insulated joints are also available which are applied currently in tracks of MÁV. Research methods To achieve planned goals the following research methods are used: – literature review, – laboratory tests, – field tests, – FEM analysis. The authors introduce the results related only to laboratory tests. Several laboratory tests were executed on different rail system IRJs [1], e.g. static shear tests of glue materials, static 3-point-bending tests before dynamic fatigue tests, 3-point dynamic bending fatigue tests with 3.5 million loading cycles, static 3-pointbending tests after dynamic fatigue tests, static 3-point-bending tests after dynamic bending tests until breakage, static axial pulling tests until breakage. Static and dynamic bending and pulling tests were conducted on IRJs made with two different glue materials, as well as IRJs without glue material were also tested. Rail systems were three different types: MÁV48, 54E1 (UIC54) and 60E1 (UIC60). Summary/results The authors represents the results of literature review [1], [3] as well as laboratory tests related to investigated GIRJs in figures, equations, calculations, etc. made between years 2015 and 2017. The behaviour of the GIRJs before and after dynamic fatigue tests can be compared, so the 'modification factors' are determined. As IRJs without glue material were also tested, the effect of glue material is phrased. Adequate glue material was chosen for further laboratory tests and field test, as well.

Index Terms: erosion, 3D model, event-based model, initial moisture, rainfall event
The scope of this study is an evaluation of potential soil water erosion using two physically-based erosion models EROSION-2D and EROSION-3D. These two models are event-based, calculating potential soil water erosion during the real measured rainfall event. The calculations of both erosion models take advantage of DEM, precipitation and soil parameters, which are established in the specific Parameter catalogue. The potential soil water erosion was modelled in two small catchments in the Myjava Hill Land (Slovakia), using 8 soil moisture scenarios and two different crops. Considering the last 35 years of rainfall records at the Myjava meteorological station, long-term rainfall events, and two storm rainfall events, appearing during one day, were applied in modelling. The application of presented models were confronted with the real measured data, and the results from models were statistically analysed to figure out the differences between model´s functional possibilities. The results of scenarios modelling proved the strong interaction and impact between the values of input factors and results of potential soil erosion, and also evident differences between the erosion models.

Index Terms: reliability engineering, combinatorial tools, processing networks
Reliability is one of the most important properties of processing systems, still it is very difficult, if possible to determine the reliability of a complex process. One of the main reasons for that is the lack of general framework covering process systems engineering and reliability engineering. Since these two areas are based on different mathematical basis, a more general frame is needed that can cover both. In the present work, it has been shown that the axioms based process network synthesis (PNS) method, the so-called P-graph framework, can conveniently cover and integrate these two areas. The method developed on the basis of this framework for reliability analysis is general and can effectively analyse complex, highly interconnected processing networks. A formerly unavailable formula, the system reliability formula has also been defined for processing networks. The focus of the present work is on structures of processing systems, all statements are general and independent of the mathematical models assigned to the units of the system. All algorithms are formally given in the paper together with the solutions of challenging problems.

The main spectacle of Szigetvár is the castle and its surroundings. However, the area, between the castle and the moat, have to be restored. The new feature of this area was the goal of the competition in summer 2017. The planning area was the whole castle park. but the interior part of the castle was not the part of the task, because it has been restored recently. In our plan the main elements of the new landscape are the two promenades. The Two, new pavilions are located along these promenades. The renewal of surroundings of the castle contrasts with its pronounced appearance. One of the pavilions is situated at the south, works as the main entrance, the other is at north with catering function The traffic goal is formation of teeming pedestrian and cyclist routes. The new landscape is filled with elements such as sport fields and playground. In our plan there are many possibilities to change the park lively with liveable, turistically attractive places, with this, the park can be the most important public garden in Szigetvár.

Evaluation of mixing in anoxic tanks in wastewater treatment PAPP Tamás*1 and KARCHES Tamás* *Institute
of Water Supply and Environmental Engineering, National University of Public Service, Budapest, Hungary
Index Terms: anoxic mixing, mixer performance, wastewater treatment
Application of mixers in wastewater treatment is essential to homogenise the suspended biomass. In anaerobic or anoxic reactors there is no aeration, thus mixers should be applied. Performance of mixing is based on the mixer geometry, rotational speed, the location and fluid properties such as density and viscosity. For evaluation of the mixing efficiency, generally field measurements are performed (e.g. tracer study or velocity field) which can be resource demanding. Numerical calculations could be an effective tool to gain reliable cost-effective solutions and various simulation alternatives can be compared. In this research an anoxic tank with two mixers were examined at different rotational speed of the mixers. The outcome was that the scenario with the lowest rotational speed did not provided sufficient mixing, the high rotational speed caused high velocities which may break down the flocs and results lower residence time. The results revealed that an optimal operation could be achieved applying flow simulations.

Index Terms: Lake Riha, habitat, wetland, water framework directive, water catchment management plans
Lake Riha is a protected oxbow lake on the Mohács Island. Wetlands across Europe suffered the greatest damages of all habitats. The state of surface waters is determined by their ecological and chemical conditions. The ecological state is defined by the physico-chemical, hydromorphological and biological characteristics of the water, while the chemical state depends on the measured concentration of contaminants. The flora and fauna of stagnant water bodies and rivers respond sensitively and specifically to such impacts. The Water Framework Directive (WFD) of the European Union (2000/60/EK) aims to provide solutions for this situation. In Hungary Water Catchment Management Plans (WCMPs) mean the tools for the implementation of the WFD.

Index Terms: Short text evaluation; Neural network; Convolutional Neural Network;
The aim of the research is to present a technique which uses machine learning to process the short text answers with Hungarian language. The processing is based on a special neural network, the convolutional neural network, which, as well as in image processing, has repeatedly proven remarkable efficiency in the case of processing short text answers. To achieve precise classification for training and recall grammatically consistent answers and the conversion of the text to the input are inevitable. To convert the input, CBOW and Skip-Gram models will be used, resulting in a model that will be able to evaluate the Hungarian short text answers. In this paper a method which is based on convolutional neural network for processing Hungarian short text answers is presented, including the mapping of the input and the spelling check and correction. Test results of the proposed method and a comparison with the results of the static method used by the Short Text Response Module of the eMax (intelligent assessment system for e-learning) system of Óbuda University.

Improvement possibilities in the Information Technology support of the control of road traffic PINTÉR Hajnalka*1 and MELEGH Gábor* *
Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: transportation registry, transportation safety, transportation informatics
In 2009, 34500 people died in accidents in the public roads of the European Union. The main reason for the great number of accidents is the technical condition of the vehicles, or the failure to respect the road traffic regulations. The purpose of this work is to present how the different electronic registers related to road traffic could be used efficiently during the control of road traffic. First, the process of the development of roadside controls and registers is presented briefly, then there is an overview about the already developed registers. After these, there is a description about the methods with the help of which these central registers could be optimized. Optimisation has two aspects. One is the data purity, the other is the use of the data included in the registers during the roadside controls. The use of the data of the registers during the control has numerous examples in the national and international practice, but these are mainly related to a partial task, like checking the payment of toll. The purpose of the work is to present that the available data - after some optimization - could be used in a much wider range.

Generally, engineering projects are getting bigger and more complex to handle. Thanks to technical developments, managers have the opportunity to plan precisely the execution of their projects and calculate the critical paths of those projects, regardless types and sizes. However, these results are too theoretical; in many cases they cannot keep the predetermined partial deadlines, so the end of the project will be postponed. The aim of our research is to make methodology improvements in project planning by applying Fuzzy-logic. Thereby the project planning can get to a higher level, because this technique could result in more realistic outcomes.

Index Terms: Energy efficiency, Thermal comfort, Optimization, Decision-making tool.
The passive strategy is the most effective strategy for energy efficiency and thermal comfort either in newly constructed or in retrofitting existing buildings. The optimization is a process or methodology of making a system or decision as fully perfect. In the optimization process, the decision-making tool should be properly set in order to cover the described configurations. This paper presents approaches to explore reduced in energy consumption and increasing the comfort hours in the residential buildings by optimizing passive measure strategies through investigating different scenarios: thermal insulation, building orientation, window-wall ratio, pane glazing, etc. The approaches are supported by computational techniques for five typical residential buildings in Sulaimani city In Iraq and simulation-based optimizations. In addition, the decision support tool was proposed to complete the optimization process in order, to formulate the optimum solution. Furthermore, the total convenient passive strategies for the residential building typologies was summarized and proposed as an optimal solution in terms of energy and thermal comfort efficiency.

Index Terms: facade, adaptability, shading strategies, insolation, thermal comfort
The facades building becomes an integral part of the climate concept, they are crucial to energy consumption and comfort within buildings, therefore it should be able to respond and adapt its properties and components with the immediate environment. In hot and dry climates region, shading is one of the most important design strategies due to the exposure and the intense amount of incident solar radiation (insolation) reaching the building's surfaces which result in high cooling energy consumption and indoor discomfort; sun control and shading devices strategies plays an important role in regulating the energy demands and global climate. The study focused on analysing a residential building in the biggest district of Biskra City (South-East of Algeria). the analysis is aimed to determine the problems by assessing the feeling of the occupants towards the thermal comfort of the buildings, and the Sunlit time within the shading elements of the building facades, giving alternative solutions to minimize the exposure, and optimize the indoor temperature, then comparing the results with dynamic analysis using simulation software, and Vi-suite addon for Blender. The results shown that the shading elements on the building facades, their strategic placements and accurate designs can further improve and decrease the internal temperature of the building in this context.

Index Terms: panel buildings, refurbishing, BIM
The panel technology was used in the 20th century in Hungary. This kind of manufacturing process made possible to build more than 500.000 flat. As a consequence of mass production the quality and the size of the living area is not convenient nowadays. Nevertheless the biggest problem is that the planned lifetime of the structures is nearing to the end. Several studies examine the feasibility of a modernization, but there is no complex solution for that. The variations of the technology make it more difficult, because each panel factory had its own improvements, they used different materials and composites. How to find the optimal way of the measuring, planning and refurbishing process? The Building Information Modelling (BIM) could be a tool with some other modern technologies to find the correct methodology.

Assessments of sewer systems are key tools in verification of sewer hydraulic capacity. Rain sewers and combined sewers are most susceptible regarding system overload and so while assessing them; proper choice of design rainfall is inevitable. The calculation of design rainfall is time-consuming and inefficient and that was the reason that leads to development of design rainfall analysis tool in order to minimize the length of the calculation process of design rainfall. The tool incorporates calculation of design rainfall depending on the specified area of interest within Slovakia and chosen periodicity, allows block rain, reduced block rain and synthetic rain to be calculated with the possibility of their mutual comparison, and also serves to generate background data for further use in form of PDF and XLS files.

Unsuitable feed water quality causes fouling and serious decrease in membrane permeability during the operation of reverse osmosis filters, which leads to costly operation and low contaminant removal efficiency. Pressure losses on a small reverse osmosis equipment with a permeate capacity of 100 L/h were investigated for almost a year. Changes in permeability and cleaning methods were investigated with different feed water qualities. Long filtration periods without cleaning had been achieved and critical values for some chemical parameters in the feed water were determined.

Formex algebra adaptation into parametric design tools SÁRKÖZI Réka*1, IVÁNYI Péter* and SZÉLL Attila Béla* *
Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: parametric design, structural morphology, space structures
The aim of this presentation is to introduce the adaptation of formex algebra to the parametric design software Grasshopper. Formex algebra is a mathematical system created by Hoshyar Nooshin and Peter Disney, primarily used for planning structural systems such like truss-grid domes and vaults, together with the programming language Formian. The goal of the adaptation is to allow architects of planning truss-grid structures easily with parametric design tools. To produce regular structures coordinate system transformations are used, and the structures are defined in polar, spherical and cylindrical coordinate systems. Owing to the abilities of the parametric design software it is possible to apply further modifications on the structures and gain special forms. The adaptation covers all of the basic dome and vault types introduced in the paper Formex Configuration processing I. in a logical order based on the mathematical similarities of the structures and take into account the characteristics of Grasshopper. It also contains additional structural possibilities like making double layer grids in all basic geometry forms, but does not cover foldable systems and some modifications presented in the mentioned paper which are already given by the tools of Grasshopper. The adaptation of formex algebra and the parametric workflow of Grasshopper together give the possibility of quick and easy design and optimisation of special truss-grid structures.

Index Terms: experimental studies building physics investigations of condensation water on plaster surfaces, plaster surface, condensation water, algae growth
Recently several authors have made attention to the problem of condensation water on plaster surfaces. They all were looking for a sophisticated measurement method for detecting the condensation amount and always stressed again that the gravimetric determination method which spot amount of water volume by means of a fleece, and useful results can provide. However, I have it asked the question of when exactly the right time for provisions of condensation water quantity with a fleece and a spring balance is. When the point is reached at which the condensate has reached its greatest amount? Condensation analyses are time-consuming and cumbersome in open field test; or carry out condensation analysis under laboratory conditions. To produce the condensate film in the laboratory, an artificial cooling of the sample carrier (eg with a circulating chiller and cooling plates) is necessary. Witch building physics investigations could get some exploration on condensation water? Method: Contact angle W- value Condensation water measurement Algue growth test Some of these experimental setups with different methods were necessary to find a non-contact and nondestructive technique that seems appropriate to carry out a coating thickness measurement. It was found that the monthly condensation time other hand is up to 240 hours, the rain time per month only about 22 hours. [1] HM. KÜNZEL and KRUS formulated to in [2]: ""... The annual rain amount in Holzkirchen is about ten times greater than the annual amount of condensation on highly insulated façade, the humidity conditions depend on the facade decisively on the water retention and moisture storage properties of the façade surface layers"". This study allows conclusions to the fact that one of the main factors for the algae growth are the moisture films on the component surface. Through further test series of measurements with different plastering systems could sustainable Solution for optimization of the facade systems are developed without biocides. REFERENCES [1] [2]

The new proposed railway network in city of Bratislava, which is supposed to be connected to the airport, is an integral part of Trans-European Network for Transport (TEN-T). Certain section of the planned railway should be constructed along Carpathian Mountains through underground tunnels. However, the construction of this underground tunnel will adversely affect the groundwater flow regime. Therefore, it was necessary to establish a 2D finite element numerical model to evaluate the implementation of this railway tunnel on the groundwater regime as well as means of technical measures to reduce the impacts. The paper presents the model result, analyses, prognosis as well as possible methods control the groundwater level regime in the aquifer that could be affected by the railway tunnel construction

Community architecture: Case studies of participatory design in the Philippines SHIH, Rowell Ray*1 *
University of San Carlos, Philippines
Index Terms: Community architecture, participative design, community based designs
The concept of Community Architecture exists under different names: Community Planning, Community Design and Participatory Design. These are all referring to the same meaning, which is people’s participation in design, planning and architecture. Community participation in design and planning emerged from a growing realization that the mismanagement of the physical environment is a major factor contributing to the social and economic ills of the world. Existing literature has discussed how the Participatory Design approach empowers the citizens in the community to address environmental and social challenges via collective participation, deliberative governance and collective intelligence in order to arrive at collective outcomes for the common good. Moreover, researchers have also shown that architects and planners must do everything possible to make architecture less about the representation of its designers and more about the representation of its users. Due to the onslaught of multiple natural disasters, the architects and designers in the Philippines began to explore various community projects to help the affected communities. The project presented here demonstrates two (2) case studies chronicling community-based design projects in the Philippines using Participative Design Workshops. The workshops highlight the participatory design process, including the phases of participation, who should participate and the consequences of participation. The first case study presents the design and methodology of blackboard modular furniture that can be converted to an emergency partition and storage for emergency provisions. These modular partitions provide a sense of privacy for each of the affected families, which are needed in any evacuation centres, particularly on the sick, aged, menstruating women and lactating mothers, among others. By using the participative design method, the design will, therefore, ensure user acceptability by the stakeholders. The resulting design allows for adaptability and portability, which therefore reduce material waste and cost. The second case study exhibits the use of participatory design in the development of a community housing project for the twelve (12) family members in Caloocan City, Philippines. All families have been living as informal settlers of which portions of it were considered unsafe due to recurrent flooding during heavy rains. Through comprehensive discussions and exchanges between the architects and planners, a schematic design of the housing unit was attained that was affordable to the families. Both of the case studies have shown that the main source of user satisfaction is not the degree to which a person’s needs have been met, but the feeling of having influenced the decisions. Furthermore, this study considers that architecture created in partnership with the end-users can result in meaningful physical and social benefits. The design must, therefore, be carried out between the common efforts of skilled, experienced users and design professionals. Thus, the true participation of the end-users guarantees the complete interpretation of their needs and requirements for the future sustainability of the project in addition to empowering and creating a sense of ownership among the people.

With the Modern Városok Program (’Modern Cities Program’) Pécs has gained a development opportunity with the help of which not only the buildings and premises of the university faculties participating in international training can form more sustainable, unified university campuses, but with urban planning infrastructure development is being prepared both in short and long term. One of the main development areas of the ’Modern Cities Program’ is the establishment of the ’Western Campus’.In the first stage, the formation of a migration map and the grouping of the faculties and buildings inside and outside the premises were necessary for the unified Campus. During the preparatory phase, the infrastructure connecting university areas were developed and the pedestrian and bicycle road networks were redesigned/expanded. In the second phase, the faculties were complemented in accordance with their needs, some faculties were redesigned inside the buiding (Faculty of Pharmacy), others were enlarged (Faculty of Sciences), but new buildings were also designed (Medical School, Faculty of Engineering and Information Technology ÉG 8156). The International Studies Centre and the Centre for Foreign Languages are placed in this homogeneous structure, which also indicates the essence of the Campus.

Plant leaf structure analysis with formal languages STORCZ Tamás*1, ERCSEY Zsolt* and VÁRADY Géza* *Faculty
of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: leaf, structure, skeleton, formal languages
In precision agriculture, leaf recognition is crucial to identify plant species. As published deep convolutional neural network do these recognition tasks with 4.1% top 5 error rate. It is slightly better than 5.1% of human experts. But this result is a bit illusive, because top 5 error rate is not useful in precision agriculture, and top 1 error rates for 1000 species are around 30%. This task is more difficult for ragweed (Ambrosia Artemisiifolia), because it’s leafs change very much through periods of growing, as it is shown on figure. There are two main issues still opened. First, we have no measure of similarity of species, therefore we do not know how far we are from the theoretical limit of classification accuracy. Second, even if DNNs could perform almost 100%, we would not be able to translate DNN structures to domain expert knowledge. The main targets of this experiment are to find a structure descriptor and to check whether this descriptor is useful to identify the ragweed by leafs. According to the hypothesis, the basic structure of ragweed leafs is based on similar basic features. Structure description is made by skeletons; analysis is done by creating and applying a formal language to formalize features of the searched species. To decrease the effect of morphological diversity of ragweed leaf and partial occlusion, we are modifying the language structure and extend it not just to generate a logical parse output, but to try to estimate the probability of true positive and true negative cases.

Optical 3D depth estimation methods STORCZ Tamás*1 and VÁRADY Géza† *
†Faculty

Index Terms: depth perception, camera, machine vision
Depth perception plays more and more role in computer vision applications. Games, car navigation systems, 3D scanning any many other fields use 3D data for their calculations. Although better and better spatial resolution is a need in most of the applications, there are fields, where different limitations hamstrung this. There are different types of sensors on the market, which aim the fast and accurate depth perception. Most of them utilize active techniques, where some signals have to be sent out and read back for measuring distance in the given direction. Such techniques involve ultra-sonic waves or infra-light or laser lights at different wavelengths. These active techniques need expensive devices, extra power, extra sensors and active parts possibly interfering with the environment, are slower and have limitations based on the used active components (Eg. sun light against IR sensors). All these requirements endure the strongly limited battery capacities of drones and autonomous vehicles. Accuracy costs power and we don’t need high resolution in all cases. For fast navigation, low resolution, but fast depth perception could be sufficient. Since drones are carrying one or more cameras by default, using them also for depth estimation could save energy and weight, both very important for longer operation. Using mono methods, based on image focus and binocular methods as stereo vision can provide basic depth estimation, what could be sufficient for fast decisions in directional progress. Combining the low resolution mono methods and the more complex stereo methods could result in a cheap and fast depth estimation. The aim of the current work is to explore the possibilities of such arrangements. Potential subsidiary advantages and preliminary results will be presented.

Index Terms: zinc, corrosion rate, map, aggressiveness of the environment, parameters
The subject of this research was influence of the environmental parameters, like temperature, humidity and pollutants, on the corrosion rate of the zinc protective coating of the steel structural elements. Zinc is usually used to protect those elements against corrosion. The idea was to study the corrosion of zinc in different parts of Slovak Republic in order to create the so-called corrosion map of the country. The corrosion rate of zinc rcorr was calculated according to standard ISO 9223. Results have shown that both the input parameters, as well as the corrosion rate of zinc, are changing with time.

Expert control system of shipping operation on the Gabčíkovo project ŠULEK, Peter* and KINCZER, Tomas*1 *Faculty
of Civil Engineering, Slovak University of Technology in Bratislava, Slovakia
Index Terms: the Gabčíkovo project, Danube, expert control systems, optimization model, heuristic optimization methods
Task of shipping operations control of the Gabčíkovo project (GAP) is to synchronise several requirements. These come from versatility of GAP and must meet following goals: operation of GAP must be effective (maximization of the ship locks capacity, maximization of income from electricity production in hydropower plant), reliability if operation of the ship locks must not be limited or endangered by defects on technology parts of the ship locks caused by illegal parameters of water flow in the filling and emptying system (F/ES), shipping safety must not be endangered or limited by unsuitable parameters of river way (navigable depth below minimal shipping depths in ford sections caused by flow changes on GAP and ships crushing into riverbed of the Danube river) By taking these goals into account, we can, in general, define operation of GAP as complex multicriterial optimization task with much technological, water management, energetic and environmental constrains. Standard approach in solving this problem includes elaboration of optimization or simulation model of GAP operation. If mathematical description of problem does not exist, “classic” expert control system management must be applied. Based on above stated criteria, most effective approach to this problem appears to be creating software application that combines both approaches. In this case, Expert control system of shipping operation on GAP (ECS) will be software application to model hydraulic links and hydraulic regimes (discharges, water levels and flow velocities) based on relevant inputs on the ship locks and whole section of the Danube river, that is affected by GAP operation. Model of shipping operation should be modelled to meet following goals: minimalization of ship’s delay while waiting to transit and minimalization of destruction parameters due to fast flowing water in the filling and emptying system, assuring the shipping safety by keeping parameters of river specially on ford sections of river on whole part of river affected by GAP. The paper describes architecture of proposed Expert control system and focuses mainly on analysing suitability of heuristic optimization methods for solving above the stated optimization problems.

Index Terms: transportation economy, transportation geography, spatial econometrics, separation effect, border crossings
Hungary is frequently referred as a transit country, because of numerous important transit routes going through the country. The easiest way to analyse transit traffic is to investigate the composition and direction of traffic at border points. Accordingly, the spatial econometric analysis applied in this paper is focused to model heavy good vehicle flows through border gates. The main explanatory factors of the model – from which the regression variables are originated – are the role of international transportation connection (e.g. different networks, categories, etc.), and the role of the nearby countries.

Novel k-nearest neighbour-based control group selection methods SZEKÉR Szabolcs*1 and VATHY-FOGARASSY Ágnes* *Department

Index Terms: k-nearest neighbour, simulated annealing, experimental group, control group, distance minimization
Many experiments in social sciences, natural science and engineering need comparative statistical analysis. In these studies, data from an experimental group is compared with data from a control group. These two groups should be identical in every respect except one: the difference is in the independent variable. It is constant in the control group and changed for the experimental group. The most commonly used method for control group selection is stratified sampling. The main drawback of stratified sampling lies within the strata: numerous strata makes control group selection difficult and, if the population is inadequate, almost impossible. In addition, stratified sampling cannot deal with continuous data. In this work we propose two novel, k nearest neighbour-based control group selection methods to avoid the aforementioned problems. Both algorithms handle the elements of the experimental and control groups as N-dimensional data points in the N-dimensional space and approaches control group selection as a distance minimization problem. The first one uses a unique error function to deal with conflicts of similar elements, while the second one extends the previous one, which tends to find a local optimum, by using simulated annealing. Both algorithms were tested on real (live) and benchmark datasets, and practical results show that the suggested methods are capable of selecting an adequate control group for the examined experimental group, making them usable in scenarios where stratified sampling is failing.

Improving graphics programming with shader tests SZŰCS Ádám István*1 *Faculty
of Informatics, Eötvös Loránd University, Budapest, Hungary
Index Terms: gpu vulkan shader testing spirv spirv-x c++
We present an automated model for finding defects in shading algorithms for graphics rendering and compute workloads. A key challenge in shading algorithm testing is the lack of an oracle that can determine the quality and the output of a custom shading algorithm; this is crucial in graphics workloads because expensive assets are often wasted on tackling these problems by often sitting an experienced graphics programmer at the task. Our model builds on recent shader compiler and GPU programming API advances in Vulkan and SPIR-V, SPIRV-X and leverages equivalencies between C99 and C++. Alongside with transformation of graphics and compute shaders we designed a methodology which based on a graph representation to ease up creating graphics and compute pipelines in modern scientific and commercial software projects. Our findings show that utilizing the demonstrated technology can improve quality whilst increasing productivity marginally.

In this article we examine and analyse the Jenkins processes, developer streams, development processes, automated testing tools and automated tests involved by the means of choosing the development of telecommunication-related software. Our intention was to find out whether automated tests related to the Jenkins process can increase the stability of the development environment and the corresponding test environments, and thus, the quality of the product. We are going to examine the attributes of automated tests related to Jenkins process and determine levels of testing based on them. Likewise, we examine quality assurance parameters, how and where can they be connected to Jenkins processes, and how increased quality – both during development and in the product – may be achieved by monitoring quality assurance parameters while running automated tests.

Index Terms: University development,, Public spaces
The university faculties are situated in different parts of the city and they are not connected to each other. The faculties are located in minimal areas, they are surrounded by residential and public functions. The communication between the faculties and the transport network are not solved for the students and for the city. Traditional campuses have not been established around the universities and the development goals of the university to create them were ineffective. The University of Pécs – as a campus – can only work optimally if the faculties and their surroundings are interconnected by suitable transport, infrastructure network. Within the framework of ’Modern Cities’ University Development Program, it is possible to reconsider the existing premises and to regroup the faculties – when the disunity of the Faculty of Engineering was solved, the significant property stock of the campus in Rókus street partly lost its function due to reorganization. The maintenance of the cadastre in its current form is expensive due to its under-utilized operation. However, the existing properties should be considered an opportunity rather than a problem. With the planned increase in the educational capacity of the Faculty of Pharmacy, we are able to create spaces for transparent education of international standards with a functional change in new emerging development areas in the existing buildings.

Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: lightning protection, upward discharges, modelling, simulation, PMAV, wind turbines, high structures
For the tall buildings, the design of the system is a challenge to the experts of lightning protection. Although, there are editing techniques, how lightning protection systems can be built, but the design of the effective system requires a different approach than most of the people are currently using. This category includes Skyscrapers (which are higher than 100 meters) and wind turbines, which are increasingly spread. In either case, we cannot neglect the number of upward, positive strikes and strikes which strike into the side of the tower. In the case of later, the increasing nominal power increases the dimensions and the risk of a strike, too. Therefore, their expected lifetime may be shortened and we have to rethink and refine the classical space calculation models. In our work, we use the method PMAV (Probability Modulated Attractive Volume) method and its measurement setups of Prof. T. Horváth as a starting point. In case of some setups, PMAV and similar methods give different results from the expected values. In the article, we made examination of wind turbines with one and two receptors. Besides that, we made some investigation to high buildings for negative and positive lightning to determinate the change of the attractive space. This is a key problem for the field of lightning protection and it has to be addressed in order to increase the efficiency of the protection systems. For the risk calculation, it is necessary the knowledge of the Ɛ (ratio of the striking distances), for which laboratory measurements are required. During the measurements, carefully selected arrangements are required. The deficiency of each arrangement, we will demonstrate through simulations and laboratory measurements.

Exploiting the advantages of renewable energy sources has been an intensively investigated issue nowadays. Both the distinguishable parts, for example the solar panels and solar cells, as well as the whole systems for renewable energy production has been developed a lot and the world tends to use more and more these natural resources. In the current paper producing heated water for a conventional household is investigated from the economic point of view. The use of solar panels of a renewable energy source, the sun, together with a boiler using conventional energy resource, the available electricity grid is considered. Three cases are thoroughly examined, namely i) the case when only solar panels are used, ii) the case when a boiler is used and iii) the joint system of solar panels together with the boiler have been considered. The study takes a one year period considering the number of hours of sunshine by months at the city of Pécs besides some other parameters, for example hot water demands as well as various electricity costs referring to the various available cost packages. The calculations also include the investment costs both for the boiler and for the solar panels. The aim was to determine which system is better and more cost efficient in the long terms and to compare the systems used. The above problem refers to a multi-period system with various demands at each period. Therefore, an unconstrained dynamic lot size model of the above problem was set up. The calculations are based on a program solution developed in C# language. To verify the model and the subsequent results achieved the process network synthesis model of the problem was also developed. The comparison of the two solution methods led to the same results. The present scientific contribution is dedicated to the 650th anniversary of the foundation of the University of Pécs, Hungary.

Review and systemization of the traditional yurt TSOVOODAVAA, Gantumur*1 and KISTELEGDI István* *Faculty
of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: vernacular architecture, nomadic, culture, extreme weather condition, energy performance
The yurt is one of ancient living unit for the nomadic cultural country. The yurt is nomadic vernacular architecture which developed during the 3000 years. There are 31 counties using the yurt, out of which 13 of them use its traditional yurt around the world. Basically yurts used as residential housings and also to some extent, for commercial and touristic purposes under different climates. Analysing existing professional literature, as well as scientific publications it is apparent that besides architectural and structural topics there is no existing investigation or published paper about building physics analysis of these buildings. Current research aims to create a database about the energy and climate comfort qualities of traditional yurts using dynamic calculation tools. As a result, we intend to learn from the traditional yurt technology and we plan to develop a completely new and modern building based on the yurt-experiments. Firstly, finding optimal solutions for a contemporary “yurt-building” should be applied under Mongolian climate conditions, since this form of housing is still used in this country, and, in addition, the comfort and energy performance of the yurts were surprisingly satisfactory under extreme weather conditions, by temperature differences between summer and winter of approx. 80 K.

Preservation of sacral monuments 1945–1989 in consideration of professional press of the era URBÁN Erzsébet*1 *Department
of History of Architecture and Monument Preservation, Faculty of Architecture, Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: monument preservation, church reconstructions, secularism
The formerly intensive church building activity has been drastically fallen back by the communist takeover in Hungary after 1945. The historically significant church architectural representation was almost interrupted because of the secularization: building constructions of the Church were inhibited by the political situation and only in exceptional cases – often with serious sacrifices – could be architecturally qualitative and valuable new buildings built. The immovable estate of the Church became tithe of the former after the nationalizations, thus the architectural activity of the Church could fulfil itself in the maintenance and reconstruction of the sacral monuments. At the same time the state power wanted a total control and monitoring over the operation of the Churches, so the State Office for Church Affairs (=ÁEH) was established in 1951, and thereafter its contribution was essentially necessary for any permission to reconstruct a listed church building. The accentuated significance of the church monuments springs not only from the fact that they number almost the one third of the complete listed building heritage, but they also have highlighted role thanks to their construction history and immaterial spiritual legacy of the Churches. Reconstructions of sacral monuments could also serve political aims: partly they demonstrated that the built church heritage had an important place in the representation of the socialist state (pretending religious freedom); then again, the religious meaning was de-emphasized by the accentuation of sacral values as national heritage. It is instructive to examine the maintenance of church monuments in a period overloaded with communistsocialist ideology and hardship of the secularization, in such an era, when the original symbolism of sacral buildings were absolutely contradiction with the atheist ideology of the political power. The research tries to show a comprehensive picture about the church reconstructions between 1945–1989 through the overview of the professional press of the period. Fluctuations in the quantity and characters of the reconstructions can be traceable by analysis of the compiled database, which can draw parallels with the most significant political and church historical events (moreover those monument preservation specialities can be perceptible, which features just the sacral function buildings). The study tries to highlight unique problems through a critical approach to support even more efficient sacral monument preservation in the future.

Laser scan matching based simultaneous localization and mapping in robot navigation using Fuzzy Logic VÁMOSSY Zoltán* and KUMAR, Neerendra*1 *John

Index Terms: robot navigation, laser scan matching, SLAM
In robot navigation, the simultaneous localization and mapping (SLAM) is a key concept and therefore, attracted many of the researchers in recent time as in [1]–[3]. SLAM yields a map and keeps track of the robot in the navigation environment which may consists other objects too. Laser scanner is one of the most common sensor used to execute SLAM [4], [5], [6], [7]. Using a laser scan, the Normal Distribution Transform (NDT) can model the distribution of all two dimensional points around the robot. Two successive laser scans can be aligned using NDT to recover the translation and rotational parameters between the two scan positions. A map can be defined as the collection of laser scans along with their global poses [8]. In the process of alignment of two laser scans, the point of the laser scan sample of the second scan in its coordinate frame is mapped into the first scan's coordinate frame. Importantly, This mapping can be said optimal if the sum of the normal distributions of mapped points of second scan into first one using the mean and covariance of the NDT of the first scan is maximum. The fuzzy logic can be applied to such kind of problems as presented in [9].The present work focuses on the implementation of the fuzzy logic to make the above process convenient to find the necessary parameters for localization and mapping. The experimental work is carried out on Gazebo simulator and on a real Turtlebot type robot using MATLAB software. The results are shown by figures. REFERENCES [1] [2] [3] [4] [5] [6] [7] [8] [9]

Index Terms: colour correction, reference
Colour vision is a learned process of the human eye. Receptors in the eye can adapt to the actual illumination and can also compensate unbalanced colours. The reflected spectrum of the electromagnetic waves the hits our eyes depend on two parameters. The first is the illuminators spectral power distribution (SPD), the second is the surfaces spectral reflectance. In many cases, we want to use the spectral reflectance parameters of objects. At fixed illumination, this can be called also colour and can be handled by numbers in digital images. With changing illumination, absolute colour values will change, also the numeric representation of colours will differ under different illumination. This can lead to lose objects tracked by colour or to not being able to compare colour information in two images taken at different moments. Expensive camera systems can put some extra meta-data information into the images. There are several applications and devices today, with cheap or mid-range camera systems, where these information is not provided. The idea is, to put the necessary extra information to these images. The aim of the research is to develop a small, portable extension that can be fitted to most of the cheap camera systems and can provide some of the additional information of illumination. This could make the post process or even the real-time process of image data, especially colour data possible. Our current drone research and applications and similar applications could be highly improved by this.

Index Terms: stone masonry arch, FRP, small scale laboratory model, material properties
Nowadays the masonry arches lost their importance and instead of them concrete or steel structures are in use. However, there are lot of existing masonry arch structures which usually protected. Therefore, their reconstruction and determination of their load bearing capacity is very important issue. Sometimes the load bearing capacity of them is need to be increased to fit into the new requirements. It is necessary to understand the behaviour of these structures, but the investigation of an old structure is very complicated. Nevertheless, lot of test can be performed on a smaller model under laboratory conditions. It is easier to understand the structural behaviour and determine the parameters which have influence to the load bearing capacity of them. Furthermore, according to laboratory test results it is easier to decide the best reinforcement method. It gives also the chance to build and verify a numerical model which can be used for modelling existing structures as well. Destructive tests of stone masonry arches under laboratory conditions were performed in this research. The same small scale laboratory model was tested with and without reinforcement to determine the differences in structural behaviour and in load bearing capacity. FRP plates were used to reinforce the stone masonry arch. The properties of the building materials of the stone masonry arches were tested before the construction of the structures. The results give the possibility to build a more accurate verified numerical model. The research presents the results and experiences of the construction, loading of small scale stone masonry arch. Give a comparison between the behaviour of reinforced and unreinforced structure.

Experimental studies on the moisture-dependent spread of injection agents and conclusions WALTER, Astrid*1 and VENZMER, Helmuth* *University

Index Terms: injection agents, spread of injection agents, modelling of spread of injection agents
Additional horizontal sealing in mineral building materials often produce insufficient or varying results though the application of the injection agent was carried out according to the manufacturers´ specifications. Currently there is no scientific explanation for this and therefore I started my experimental studies. The main idea was to resolve the question if the increasing filling of the capillary pores of mineral building materials with water (and therefore the degree of moisture penetration) can be connected with the varying spreading of the injection agent. Based on the test procedure of the Dahlberg Institute in Wismar/Germany test series were started, the most important results are briefly presented below. Different degrees of moisture penetration were set on samples of bricks and mortar cubes and hydrophobic injection agents were applied to the test specimen. After dividing the samples waterdrops were applied on the fracture surface and the hydrophobic effect could be shown by waterdrops remaining on the treated surface. This effect is also varying for different injection agents. As a result the degree of the spreading of the injection agent was inversely proportional to the degree of moisture penetration. Consequently there is a dependence of the above mentioned parameters and together with Prof. Venzmer (University of Applied Sciences in Wismar/Germany) I developed a modelling of the spreading of injection agents in dependence of the existing degree of moisture penetration of building materials, here shown e.g. for bricks. At present the test series are still continued. Further important conclusions: • The modelling represents the spreading of the injection agent not only in a visually way but also by means of physical parameters. • The spreading of the injection agent and the distance between the drilling holes must be well matched -> the modelling can be used to calculate the borehole distances. • The degree of moisture penetration has to be considered regarding e.g. the choice of the method of the application and the injection agent. • Injection agents with same mode of action may cause varying results -> effect on spreading • Information concerning borehole distances and applied quantities of injection agents are not generalpurpose. • The spreading is determined by the building material (distribution and quantity of capillary pores) and obviously even by the chosen injection agent. • Accompanying measures at high degrees of moisture penetrations are to be considered if not absolute. Abbreviations in the picture: A spreading of injection agent (in cm, around drilling hole) D degree of moisture penetration D(g) AD spreading, dependent on moisture degree Amax max. spreading at D(g) 0% Ak correction variable (i.e. decreasing spreading in dependence of D(g) kim permeability of injection agent, materialdependent, values are stated in cm per % moisture degree (Ref: Venzmer/Walter)

Index Terms: dwelling, characteristic, architecture, decoration
Dwelling, which is the customary appellation of traditional folk residential buildings with regional and ethnic characteristics, in China, it’s generally regarded as the place where ordinary people lived in. Dwelling is the earliest building type that closely related to human life, also the largest existing and continuous developed architectural form, its architectural decoration art is an important cultural heritage in our country, it condense the ancient people's hard work and wisdom, is the embodiment of spiritual culture, reflecting the deep-seated economic environment, cultural connotation, aesthetic tendencies, folk customs, traditional beliefs and other aspects. Until the Ming and Qing dynasties, the development of northern Chinese dwelling was pushed to the peak, due to the brick-making technology constantly progressed, and made the combination of brick and wooden frame structure into new construction form. The architectural form of the northern dwellings mostly is the courtyard, living with clans together, sitting north and facing south, pay attention to the lighting of the house, and mainly consisted of the gate, the hall, the door, the main room and then to the courtyard room, forming a narrow While long courtyard, the hall was the whole center. Wooden frame structure was applied to the buildings, together with the brick and soil for solid. The overall interior style of the northern dwelling is elegant and chic; its rich decorative and detailed features are the embodiment of culture, customs and aesthetic on the traditional local-style dwellings. The decoration of the northern dwellings is mostly made of wood carvings, stone carvings and brick carving, From the decorative parts, it is concentrated in the roof, cornices, doors and windows, beams, columns base, gable wall, furniture and other parts. Decorative patterns are of various themes and rich changes, and a large area of the plain wall makes many decoration parts unified in a main style, therefore, the overall decoration content does not seem too cumbersome and tedious. As time went on, gradually formed the architectural style and decorative style of northern dwellings, and the harmony between human and nature living environment, it found a new path in our country’s diverse types of traditional buildings, and established its unique distinctive characteristics.

Index Terms: urban grade separation (overpass bridge, road interchange), overpass type, Land-saving, Time-saving, Materials-saving
Reducing the space footprint, enhancing the efficiency and safety of motor vehicles and saving construction costs to enhance the efficiency of the city generalized connotation can be obtained by optimizing overpass. The first step is to compare all viable "left out first and left in later" type of ramp turns that are currently in use, identify the optimal one with generalized advantages in city efficiency. Using common 4-way overpass in intersections as an example, bridge-ramp type where all four ways are ‘to the left’ as the proposed ‘preferred bridge’ was defined in this research. Next, the analysis was conducted for this type of bypass that has appeared in theoretical works, patent literature and practice cases in history, and the reason, why this bridge type has not been widely adopted, was found out. After modifying and optimizing these negative factors, we presented herein the ‘optimized’ bridge type with feasibility and ‘preferred bridge type’ efficiency advantages, as advocated in this article, and achieved a comprehensive goal of optimizing urban interchange space efficiency. Also, by comparing with same level of bridge types, we demonstrated quantitative advantage of ‘preferred bridge type’ proposed in this article over regular overpass types.

Index Terms: cellars, porous limestone, physical and strength properties, water absorption
Investigation of cellars and other underground cavities is an important topic especially when these cavities are under urban areas. There are several cities around the world which are undercut by cellars suffering from stability problems caused by these openings. Well known examples are found in Paris (France), in Rome (Italy), in Eger, in Miskolc and in Budapest (Hungary). The cellars and cavities are often historic ones and are mainly results of previous stone quarrying activities. Nowadays they are usually abandoned or have different uses, such as wine cellar or storage facility. Most of the above listed cities hosts cellars that are cut into soft rocks like porous limestone, rhyolite tuff. etc. Recently, cellars and underground excavation increasingly influence the development of the cities because due to population growth there is a need to utilize areas where cellars are found. Therefore, the prediction of the stability of these cellars is an important issue. The first step of the stability analysis is to determine the properties of the host rock of the cellars. In this paper the porous limestone was investigated as the host rock of cellars. The properties of the porous limestone collected from different cellars of Budapest (Budafok, Budatétény, Kőbánya) were compared. Our results suggest that the density, porosity and permeability of studied samples show significant variations. These properties depend on the degree of cementation and porosity as well as on the amount of water in the pore system. The density, ultrasonic sound (US) wave propagation, uniaxial compressive strength (UCS) and Young’s modulus values of the porous limestone originated from different cellars were compared in dry and water saturated condition. The porosity and water absorption of the rocks were also investigated and compared. Furthermore, relations between the different physical properties and strength parameters of the investigated rocks were determined.

The “Beautiful Village” project was organized by the Chinese central government for the purpose of amending the imbalance between urban and rural areas. In response to this national policy, the positive village development projects aims at improving the tourism potential of the Hebei province. In view of the fact that most of the rural areas lack historical heritage and facilities to carry the tourism, a well-directed architecture and landscape design analysis was organized by local governments. This is to be able to create a new type of livable, humanized, high standard and attractive villages through design. In this way, the direction of village construction can be shown and further developed and the revival of rural areas can be realized.

The vast rural areas where contain rich historical and cultural heritages and natural resources areas are the root for the stability of China and the foundation of the Chinese nation. It is China’s historical, cultural and natural heritage as a "living fossil" and "Museum" and it is also a vehicle of Chinese traditional culture and the Chinese nation's spiritual home. With the rapid development of China's economy and society, the urban construction has been unprecedentedly supported. However, the rural areas which occupy the absolute advantage in area of land have been far behind the current development level. Take the "Beautiful Village" Project as an opportunity which is initiated by the government, by means of design to make rural indicators in line with the city, gradually change the status that the rural areas are far behind urban areas. The experiences and impressions of the architects from CAFA who took part in the architecture design for the villages are recorded in this paper. Taking the activity as a chance, the architects did lots of investigations about the inhabitation situations of the villages in China. Finding out the difficulties during the development, trying to solve the problems by practices and researches. In this way, the architects strive to design a high standard living level for the rural areas in China.

The multi-rotor flying robots, commonly known as drone are more and more widespread nowadays. One of these is the quadcopters which are hierarchic, non-linear systems, and their regulation is a complex task. In my presentation I will introduce an autonomous drone related project. In my PhD research I develop a robust solution for object identification and obstacle avoiding tasks. Previously I made case studies for intelligent pattern recognition, and actually I complete my system with optical flow detection for object identification. With the introduced method we are able to identify a moving object. This type of image processing method calculates the flow vectors and gives an opportunity to estimate the object velocity and position. For the object recognition we are using the SURF algorithm and Kalman filter for trajectory estimation. The presentation introduces the results and the basics of the optimal flow and SURF algorithms and presents the object recognition results.

NDT in Civil Engineering (with special focus on historical structures) Workshop organized for the 13th Miklós Iványi PHD&DLA Symposium Diagnostics & Analysis of Structures Research Group Department of Civil Engineering Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary

In the last few decades restoration work of historical structures has become fundamentally important worldwide. This is a difficult task for engineers, due to the difficulties of both gaining sufficient knowledge of a given structure and also choosing the most appropriate and feasible intervention technique. According to today’s practice, the necessary qualitative and quantitative information is collected through documental investigations, visual inspections, in situ and laboratory tests on materials removed out from the structures. With structures of architectural or monumental importance, Non-Destructive Test methods (NDT) have become increasingly important among the available techniques, and a large effort is being made to utilise them more effectively for the analysis of historical structures. Assessment of historical structures often requires the verification of in place material characteristics, damage state, position and geometry of elements, and other important structural characteristics. Carrying out an assessment using direct sampling or visual observation of the structure is not always possible, especially if the area of interest is hidden from view (e.g. in the case of an internal damage), physical access to the structure is restricted or other circumstances limit the number of direct material samples that are collected. In these situations the application of NDT techniques have a good potential to provide valuable information regarding the geometry and materials of the structure of interest and help establish input parameters for its numerical analysis. Because of the inherent non-damaging nature of the tests, many data can be collected and analyzed without fear of adversely affecting the structure under inspection. The number of references and projects that have utilized NDT methods for the assessment of historical structures is relatively limited in Hungary. A test programme is therefore being carried out by the Diagnostics & Analysis of Structures Research Group of the University of Pécs. The tests are aimed to assist the development of an analysis system for historical structures with the utilisation of the potential in nondestructive testing. This workshop attempts to give participants an overview on the possible use of NDT techniques for the analysis and assessment of historical structures, with a particular focus on complimentary combinations of techniques to improve the reliability of assessment.

& Analysis of Structures Research Group, Department of Civil Engineering, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms:
In the last few decades restoration work of historical structures has become fundamentally important worldwide. This is a difficult task for engineers, due to the difficulties of both gaining sufficient knowledge of a given structure and also choosing the most appropriate and feasible intervention technique. Among historic structural heritage masonry arch bridges represent a significant part. Deterioration due to aging and the increasing traffic loads make it necessary to perform detailed structural analysis on them. Based on the collected data of material properties finite element simulation could provide a sufficiently reliable information about their condition. Beside prediction of load bearing capacity, deformation analysis is also important in order to extension the service life. The paper aims to present an approached model for a masonry arch railway bridge verified on the result actual physical experiments, and gives possible solution for strengthening.

Index Terms:
Preservation and restoration of cultural heritage buildings has been a necessary and important issue not only in our country, but worldwide. However the task of conservation and renovation is considered a complex professional work, requiring the combination of science, art, and engineering. Most of our buildings are older than 50 years; renovation is expensive, because of the strict lows and the high professional and cultural expectations. In case of the necessity of a structural strengthening the price of a project can be twice as expensive. Therefore the knowledge about the exact strength of structures is of high importance. Several diagnostic procedures are commonly used in practice, such as Schmidt hammer, drilled sample analysis etc. Results of these methods are relatively exact and their variability is low, however several factors that affect the strength have to be taken into account. One of these is humidity. Psychrometry shows the condition of the structures, and helps to specify the results of the other diagnostic procedures. The practical use of these methods will be demonstrated in the presentation. The case study will show the examinations conducted by using Pendulum Schmidt Hammer, universal testing machine (with the compressive strength test used for the drilled samples), moisture meter device and SEM (scanning electron microscope).

Architects in school movement and architecture in public education GAUL Emil* *
MTA-ELTE Visual Culture Research Group
The style is very important for young people, though few of them knew what kind of technical and aesthetic learning should have a designer and manufacturer to achieve attractive appearance for an object or building. Nowadays not even rural children get experience in manipulation with material, construction, and they are not oriented in taste. For example, in modernization of buildings, putting thermal insulation glazing, the owner considers just the price, and nothing else. In this way each building gets white plastic windows. In Hungarian public education two subjects Technique, way of life, practice and Visual culture deal with material culture. Technique is taught for 8 years, visual culture for 10 years, in one class a week. Technique embraces the whole technical side of architecture in a significant quantity. E.g. in fifth grade 27 from the total of 36 classes is for learning about the residential area, making objects, and model design. The frame curriculum of Visual culture in elementary level contains 24 hours, while on lower secondary level 12 from the available 36, which amount is also appreciable for learning about environmental culture. In this subject area the form, the meaning of the form, and the aesthetic value are in the focus (Frame Curriculum 2012, 2016). One can state that public education offers considerable time to learn building, constructing, manipulation, creation form, interpretation of meaning, and so on, compared to its potential. Contents mentioned above do not belong to the area of professional knowledge, but to general culture, of course. The European practice is similar to Hungarian, in details slightly vary from it. For example, Art education is generally two years shorter, than by us, school workshop is more accentual in Scandinavian countries, and in the United Kingdom. In The Netherlands and Switzerland textile design is a rather autonomous part of handicraft. To teach in school you must have qualification in every country, even southern countries as well. In the frame of extracurricular and leisure time activity many fora offer place for introduction and presentation for different profession, like architecture, and attainment of practical and theoretical knowledge. Among others the most significant in Europe is Cultural Heritage Classes which is an initiative of the Council of Europe. In France for example more than 2 000 such centres are working, where schoolchildren can spend a week and make practical exercises, listen to classes, and take part in exhibition visits. The sites can be agricultural, or archaeological, but they are mainly architectural. In a book: Art and the built environment (Adams, 1982) a British architectural education project is mentioned, where pupils draw, analyse, redesign existing building, and publish (with the help of their teachers) their ideas in a newspaper dedicated for this purpose. That time more than 800 active group exchanged ideas through news, and manymany read it. The Hungarian movement of Kultúraktív Association entitled “Architects in School” belongs to the best present day’s international initiatives.

Shaping perspectives 0 – 99 GERZSENYI Judit*, DOBOS Botond Zsolt* *2040
Association of Young Architects in Budaörs
Its name being telling of its activities, the association has been founded by young architects with the mission to promote a stronger urban identity in their sleepy bedroom-community-hometown Budaörs where they live with their families, and the zipcode of which forms the very first part of the association's name. Importantly, the association is not only for architects; members with other professional backgrounds also joined our community, such as actor, designer, software developer, etc. Our primary objective is to shape the perspectives of our fellow local citizens, the way we all look at our built environment and perceive it. We are not targeting any specific profession or demographic groups, but aim at involving the most possible of the local inhabitants. This approach forms the core concept behind our colourful events organization that included: environmental education in schools, topical school trips for kids and their parents on how to ‘use’ our city, cultural weekend programmation with theatre play and open-air cinema, community gardening and city-market, construction of mobile playground and a conference on education on built civil environment for practicing teachers. We are also active as a local community of professional architects, and make public proposals on planning issues regarding the whole city or part of it, which we then present to the locals for discussion on the several exhibitions we organize each year around the topics of architecture and urban planning. We aim at maintaining a platform for creative local endeavours and ideas, and attempt to work closely with the local governance to interpret suggestions and criticism. Since the beginning of year 2017, we have the opportunity to operate a café which, opened in the basement of a former barn of almost 200 years of age, now becoming one of the cultural spots in town.

Architecture education in Finland HUMMELIN, Niina* *
head teacher Arkki, School of Architecture for Children and Youth, Helsinki, Finland
Arkki School of Architecture for Children and Youth originates from Finland, and is specialized in providing architectural and environmental education for children and youth. Arkki is among the most comprehensive in the world, measured by the programme’s depth, quantity and quality. Currently Arkki Schools in Finland are located in three cities: Helsinki, Espoo and Vantaa with 600+ pupils attending the weekly programs of long term architectural education. Annually c. 7000 children participate in theme courses and workshops in Finland. Arkki's exceptional pedagogical concepts inspire children to learn through inquiry learning processes and hands-on experimentation. Learning is made fun and rewarding. In Arkki, play and fantasy are used as means to discover the different phenomena of architecture. The cross-curricular architecture education program of Arkki develops higher-order skills and abilities through phenomenon-based learning. Arkki´s educational programme also enhances creativity, complex problem solving, critical thinking, communication and collaboration. In some projects children can take part in the actual design process of architecture and city planning. Through architecture education it is possible to foster a new generation of active citizens who have a deep understanding about the built environment, and who hopefully possess tools for a positive change in the future. In Arkki we believe that architectural education gives children new possibilities, means and mediums to influence the creation of our future environment, whatever their occupation is.

Vision and reality – architects in art education MARKÓ Balázs* *
Szent István University Ybl Miklós Faculty of Architecture and Civil Engineering
Let's turn Zoltán Kodály's famous saying that "music belongs to everybody" and say that architecture belongs to everybody. The quality of the built environment is a formative force of the personality, just like social or family environment. The knowledge and recognition of spatial qualities, the knowledge gained through experience is of extraordinary importance for general culture and education. The quality of the space affects the behaviour and vice versa, the bipolarity of the mechanism of action is clearly detectable. Along with urbanization development processes, the effects of the built environment are more and more affecting the human psyche. Visual stimuli move on a wide scale in negative and positive directions. People acquire naturally the positive effects of a beautiful human environment, while destructive visual pollution that is present in the process of shaping the built environment can trigger negative behavioural processes. Only a well-structured education system is capable to fight this. Architectural and environmental education at the various levels of education is essential in this struggle. From mapping games to the art of placemaking, the presence of architects is inevitable in visual education, as the toolkit for constructing covers both technical and artistic areas, and authentic architects work in both areas at master level.

Build Environment Education in Germany – how to bring architecture and heritage at school in the European Cultural Heritage year 2018 REITERER, Stephanie* *
University Regensburg, Institute for Arts Education / LAG Architektur und Schule
In 2000 the German Government set up the „Initiative for Architecture and Build Environment“. One year later the first status report on built environment in Germany put out a claim for more built environment education at schools. Most of the chambers of architecture of the federals states are proclaiming programs like „Architecture Makes School“ . In Bavaria, the Landesarbeitsgemeinschaft Architektur und Schule e.V. (LAG), which consists of a team of teachers and architects, is embossing built environment education since 2007. The project team of the LAG is initializing further education programs for teachers, architectural competitions for students, educational methods and school workshops. Since 2013 the “Architecture School Bus” – a special tool for built environment education - is driving with the LAG Project Team through Bavaria and in other federal or international states to realize school workshops between art and place making, historical architectural styles and guerilla architecture. For the Cultural Heritage Year in 2018, the LAG launched the project „LOST TRACES...“, which intends to sensitize kids, teens and young adults for discovering the living and the built cultural heritage of Europe. Historical relicts in the landscape, hidden archaeological traces, waste lands, abandoned buildings and places of change create a special fascination to the youth. This is the place and moment when cultural heritage is perceptible, beyond the authentic museum-like aestheticitation. Here is an open space available for imagination, creativity and self-determined activities. LOST TRACES... invites young people together with citizens, experts, creatives and teachers to discover lost places and hidden cultural traces, which are relevant in the European context. The young participants will be in the course of the project patrons of a chosen location. They will investigate and scrutinize it, design and treat the whole place in a playful manner only for a certain time, constructional and with a cultural dimension: special intervention or artistic set design, street art, light installations, guided tours, presentations, music and dance or common feasts might be part of the discovery and the interaction of this very place. Because of the temporary capture of the location, the lost space and its forgotten history will arise to public consciousness. Discussions will be kicked off and new ways of numerous usages will be proved. The projects will give new impulses for city development and local networks for schools and universities and the academic discourse in educational science of preservation of historical monuments.

Built environment in eco-schools SALY Erika* *
Hungarian Institute for Educational Research and Development
Since an eco-school has to deal with all aspects of environmental education, amongst eco-school criteria you can find “built environmental education” as well (e.g. forming of the inner and outer spaces of a schoolbuilding, implementation of a school garden etc.). Nevertheless there are several eco-schools that neglect this topic. A school development project of Hungarian Institute for Educational Research and Development has revealed the built environmental education as a missing topic despite the fact that the National Core Curriculum refers to it. If the schools run built environmental education themes, they do it within school subjects, so they lose the benefits of the complex learning organization forms. Probably the main cause of this situation is that the school teachers do not recognize the disciplinary and interdisciplinary educational benefits of a built environmental educational process (e.g. evolving a willowhut), cannot step out from the textbook-teaching, and do not trust in the possibilities of real-world, problembased, complex learning organization forms. Having recognized the roots of this problem we have worked out (within the project mentioned above) many interdisciplinary modules that could be good sample for teachers, students and local people to form together the inner and outer spaces of a home or a school-building. These modules present successful built environmental programs and at the same time they encourage teachers to test non-disciplinary, complex learning organization forms (theme-day, project-pedagogy, forest-school) and to integrate them into their normal way of teaching-learning.

De-a arhitectura – building with education SAVA, Mina* *
De-a Arhitectura, Bucharest, Romania
“De-a Arhitectura” Association is a Romanian organisation of architects and teachers established in 2013. The group founding members have worked together since 2011 on De-a arhitectura cultural program, a project within the Chamber of Romanian Architects, Bucharest branch, but in 2 years it became a national network. The name is difficult to translate: de-a arhitectura is a Romanian wordplay, that approximately means “let’s play the game of architecture”. ”De-a ...” is an expression children use when they name or discuss what game to play. And we all know that the best way to learn is by playing. The name does not only appeal to children, it appeals also to architects, being similar to Vitruvius De arhitectura. But the most important thing is that it suggests a game. And games have rules. Because De-a arhitectura team dream of a world where everybody is aware of the written or unwritten rules of the build environment and have a built environment common sense. These are the best tools to make better living places in the future. The idea to start with the build environment education in schools was present in the thoughts of many fellow architects. But, to make it happen, the first step was to transform built environment content into teaching materials with simple language and easy to use and attractive exercises. Three educational programs for schools have been created and applied for different age groups. Along with this programs were developed conferences for children, on architecture and creativity and various workshops, some in connection to architectural and urban events or for art museums. The next step was to make sure that this teaching material will be used in schools, and not just in a few schools and not just for a few years. This challenge, which was not obvious to the group at the beginning, implied the construction of a whole system that includes, beside the teaching materials, also training methods for teachers and built environment professionals, human resources skills, financing and project management, communication and public relations activities, knowledge about the education system and its stakeholders. The group had to learn from doing and to build up a strategy for growth and for insuring continuity that naturally leaded to its mission statement: "We build with education. Our construction grows when: -The children and the adults understand and cherish built environment values and they are active members of their communities in which they share places -The built environment professionals are involved, through education, in the society -In education, playing, experimenting and being creative are taken serious”. All De-a arhitectura teaching materials and training courses are free for their users in the public schools. The association uses many fundraising methods to make the program available for free to children and relays a lot on the pro bono work of its members and volunteers. Both the Chamber of Romanian Architects and the Romanian Union of Architects and have seen these activities as being very important and De-a arhitectura Association is helped with financial resources for the programs that are considered by the two professional organizations as strategic.

Architects in the school – the overview of the Hungarian story TATAI Mária* *Chamber
of Hungarian Architects
The first known pioneering attempts in Hungary were made in the ‘70s, when architects held study group lessons for children, and the idea was raised that children should be acquainted with architecture from an early age, in some manner and to a certain extent. In 1980 the Association of Hungarian Architects (together with three other organizations) announced a study competition: “The contents of architectural culture, and the opportunities and methods of its dissemination in public education”. The competition was fruitful, architects and educators formulated their ideas. Subsequently, educational experiments were conducted in the ‘80s in some primary and secondary schools to test methods regarding the topic. Our team managed to work with the children of a rural school (Primary School of Kerekegyháza) for eight years. Drawing and technology classes served as the framework of our project. We dubbed the subject “environmental culture”. We put the curriculum together in a way that it would not just allow for the expansion of visual and technical knowledge, or the improvement of relevant abilities; it would also allow children to experience architecture in an age-appropriate manner. In 1993, our program received an official permit as an educational alternative. Environmental culture as a subject appeared in the Teacher Training College of the University of Art and Design in the second half of the ‘80s. Environmental education (which included architecture) became an emphasized part of the “Visual Culture” educational area of the 1996 National Core Curriculum, under the heading “Object and environmental culture”. Yet at the same time, initiatives remained isolated, quality though they were. They failed to become universally known and widely used, but some still appeared sporadically in some schools (or apart from school), initiated by architects, educators or art historians. In 2011, a conference titled “Built Environmental Education in Schools” was held in the Műcsarnok (Kunsthalle Budapest). The lecturers invited by the organizers introduced some then-current projects, in which architects dealt with children and young persons. From 2012 on, the Chamber of Hungarian Architects started giving the topic higher priority and initiating study group lessons in a school. In 2013, some concepts concerning architecture once again got into the National Core Curriculum’s then-current version, thanks to the work of architects asked by the Chamber. Since then, the CHA has continued to support projects and initiatives related to the topic. It has organized a conference, published handbooks and continues to report on current projects in its regular publication. Today, more and more parallel initiatives appear in Hungary, although most of them outside school. All this supports the hope that architectural education will become more and more universally attainable, which is not only essential to the development of children’s knowledge and abilities, but is today also indispensable to improving the quality of our built environment.

Preservation of values and local knowledge in the school TÓTPÁL Judit* *
Committee for Local Collection of Values, Biatorbágy
In Biatorbágy civil organizations and individuals dealing with local history and local repository of values have been doing work serious for decades. The movement for the repository of values, which was founded couple of years ago, gives these searches a frame and connects it to a standardized nationwide system. The Committee of Repository of Values (Értéktár Bizottság (ÉTB)) is the organization, that maintains the local repository of values and it is a committee of special status of the municipality. In 2014 as the chairwoman of the committee I initiated the elaboration and integration of a program series for children into the scope of the committee’s activity, with the title „Let’s discover Biatorbágy!” („Fedezzük fel Biatorbágyot!” (FfB!)). Every elementary school in Biatorbágy participates in the by now wellfunctioning program. Project days are organized for fourth grades classes of each school. Children experience discoveries in connection with knowledge about the town, the history and the functioning of the town, as well as creative adventures with architectural themes. The program, which is financed by the municipality, has twofold aims: • on the one hand it is the reinforcement of the identity of the numerous newly moved in families1, • on the other hand, it is the sensitization of the children towards their built and natural environment.2 The book „Biatorbágy for children” (Biatorbágy gyerekeknek) will be published at the beginning of 2018 by the Municipality of Biatorbágy and the kultúrAktív Association (kultúrAktív Egyesület) to support the FfB! program and it will be available for free for every 4th grade student. 1
According to the place identity concept of Andrea Dúll, environmental psychologist, our physical environment becomes the organic part of our identity, our self-feeling, i.e. our personality, our favorite places offer us the possibility of environmental self-regulation, which is essential in the survival, through the feeling of familiarity, control and belonging. 2
The FfB!-program is the place-specific adaptation of the PreArchitektúra-program of András Cseh DLA architect. This program enables children to learn in the built and natural environment of their hometown through conscious spatial perception and building activity.
