The 12th 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 12th 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. At the end let me greet the participants of the 12th 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.

Foreword The 12th 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 and Eleventh International PhD&DLA Symposia were organized in 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 and 2015 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. All of the abstracts and papers are reviewed by the members of the Scientific Committee. 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.

Assessment of the living commodity, heating energy consumption and resources by the residential sector in city of Prishtina AHMETI, Petrit*1 and KISTELEGDI István* *
Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: Residential sector, heating energy, energy resources, living commodity
Despite the previous research regarding energy consumption by the residential in the city of Prishtina, which was based on statistical data and hypothesized results, it is very crucial to create a database with detailed data gathered on the field, to create an overall “image” of energy consumption and resources used for heating by the residential sector. The main focus of the research is to identify the main heating energy resources used by the residential sector, the level of commodity and satisfaction based on heating level within households but also the living commodity in terms of living area per individual and number of inhabitants per household. Completion of the detailed database with all needed data, is achieved by a survey which was conducted widely throughout city of Prishtina, covering the total urban area. Survey distribution throughout the city of Prishtina and separate neighbourhoods was one of the main challenges but yet the core of this research, in terms of result generation. The research results will create a clear “image” of energy resources used for heating by residential sector in general and in specific neighbourhoods in city of Prishtina, application of thermal insulation, types of windows and percentage of heated area within a household. All generated data within the research will be used and basis for further research for more detailed calculations of energy consumption by households. More empirical and measurable results may be generated in future using the actual results of this research.

Kinetic manipulator as dynamic building skin for increased efficiency and didactic design ANDROSICS Tamás*1 and KISTELEGDI István† *
Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary † János Szentágothai Research Centre, University of Pécs, Pécs, Hungary
Index Terms: dynamic building skin, didactic design
With dynamic energy and climate calculations supported building design completely new, innovative sustainable building typology can be elaborated. A unique example was implemented in 2016 September, as a demonstration centre for energy efficiency building technologies and environmental conscious lifestyle could be opened for public visitors. Basically, particular project consist of two strategic design phases: the sketch planning and the final planning workpackage, whereby different dynamic building thermal simulations helped to develop a special building design. A slideable building skin ensures thermal insulation in heating period for the adobe office and exhibition unit of the building, while in cooling season this insulation skin slides over the exhibition and event glasshall unit. In moderate transition periods the "climateskin" can be moved in front of the glasshall to deliver a shaded shelter and loggia-like terrace for outdoor activities. The presentation and paper deals with the challenges of the simulation supported design as a new and very effective building design decision making technique.

Comprehensive performance analysis of C++ smart pointers BABATI Bence* and PATAKI Norbert*1 *
Department of Programming Languages and Compilers, Faculty of Informatics, Eötvös Loránd University, Budapest, Hungary
Index Terms: C++, C++11, C++17, smart pointers, performance
Smart pointers play an important role in avoidance of memory leaks in C++. Since C++11 standard the smart pointers have become widely-used and popular tools because they let the programmers not to deal with memory deallocation and prevent the memory leaks. However, abstraction penalty occurs because of this convenience. Overhead appears when smart pointers are in-use. Abstraction penalty is related to runtime, memory usage and compilation time as well. There are many different smart pointers in the standard library that work in different ways. However, the performance difference between the smart pointers are not measured before. This paper presents a comprehensive analysis of effectiveness of smart pointers. We are looking for an alternative approach for the C++17's optional construct based on the available smart pointer constructs. Raw pointers are typical possible solution for this use-case but they have some weaknesses and modern approaches do not prefer the usage of raw pointers, so in this paper we also exclude them. We analyse the performance differences of smart pointer based on test programs.

The urban challenges of sustainable development BAJNAI László*1 *
Urban Development Plc., Budapest, Hungary
Index Terms:
THE SUSTAINABLE URBANIZATION IS A KEY TO OUR CIVILIZATION For the survival of our civilization and culture, our cities have to respond to the challenges of the sustainable development from environmental, economic, and social perspectives in the next decades. Our urbanization not only endures the environmental, social and economic processes that threaten the sustainable development but it is one of the basic of these processes. That is why we have to make a choice. We can either let the spontaneous processes that threaten our urbanization and civilization to spread or we can make the process of urbanization sustainable by planned and coordinated interventions. ENVIRONMENTAL CHALLENGES OF SUSTAINABLE URBANIZATION Urbanization is one of the key factors leading to climate change. It has significant effects on CO2 emission, energy consumption, and the social and economic progress. The growth of the suburban areas around cities and the daily commute of their residents: • produces CO2 and other greenhouse gases, • leads to an excessive waste of energy. By making the inner cities attractive for residents, the harmful spatial growth of suburban areas can be slowed down. The professional practice proves that this transformation is possible in Hungary. ECONOMIC CHALLENGES OF SUSTAINABLE URBANIZATION Another aspect of the sustainable urbanization is its economic side. The financial resources that are necessary to the transformation of urban texture can only be preserved for long time if the local and the national economy are stable. Cities are the motor of regional economic growth. It has become a consensus in Europe and Hungary that re-industrialization is crucial for the economic sustainability. Planned development of the urban texture has to meet the urban requirements of re-industrialization. SOCIAL CHALLENGES OF SUSTAINABLE URBANIZATION The social sustainability correlates with the environmental and economic sustainability. Disadvantageous social processes, such as declining population, population aging, increase of low educated people, poverty, etc., have negative effects on urban environment and the local market. The fundamental challenge of social sustainability is to stop these processes. It can only be realized by planned urban development. PERSPECTIVES Sustainable urbanization is possible. Although, planning and a lot of work is necessary to make it work. The fundamental requirement of sustainable urbanization is the implementation of a well-functioning system of planned urban development.

Determining PCU values in signalized roundabouts for certain vehicle types BARNA Szabolcs*1 and SCHUCHMANN Gábor* *
Department of Highway and Railway Engineering, Faculty of Civil Engineering, Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: Passenger car unit (PCU), Signalized roundabout, Microscopic simulation, PTV Vissim
The passenger car unit (PCU) or passenger car equivalent (PCE) is an important comparison factor that helps the traffic engineer to describe the impact of heterogeneous traffic flows on the traffic performance of the infrastructure elements, compared to homogenous passenger car flows. The purpose of this study is to determine the PCU value of certain vehicle types (e.g. buses, trucks) in signalized roundabouts. The values defined by the Hungarian standards are not the same for roundabouts and signal controlled intersections. These values are based on the weight and type of the vehicles, so it is important to know how these parameters of the vehicles influence the traffic conditions at this unique type of road junctions, to be able to conduct a correct capacity calculation. PTV Vissim microscopic simulation program was used to model different traffic volumes and compositions resulting the recommended values for the application, and a proposal for further studies in subject.

Modern methods of architectural heritage protection BERTA Csilla*1 *
Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: cultural heritage protection, monument, museal presentation
A unique and dynamic growth can be seen in the area of the cultural heritage protection. Its approach is changing in a qualitative and a quantitative way. These days, a successful museum exhibition is almost regarded as a performance. It invites the visitor to a virtual historical journey. Computer terminals, multimedia tools are used so the visitors can take part actively, and they have more interactive experience in museums. Experimental workshops are created, which require fresh architectural approach with different use of space at the monument sites. It becomes important to lead the visitor’s attention true all the exhibition. Nowadays, to protect and present the archeologic heritage could not be possible without the latest technology. The word of museums is shifting from its static state. Spatial relations can be used more freely and the building itself becomes rarity. The wrought architecture encounters the large additions, which create a pleasant contrast. My research topic is focused on the latest technologies for protecting, maintaining of our heritage monuments and also their presentation. During my DLA in Architectural studies at BMDI Doctoral School, I aim to take part in the preparation works of expanding and renovating the Cella Septichora Visiting Centre. As a first step, I create a pre-study with the presentation. I would like to expand the present perspective of contemporary heritage. The usage of some modern methods in the field of presenting our heritage monuments, there are some conflicts between the experts. Keeping that in mind, I am looking for a balance point, where the monument is able to keep its radiating dignity and devotion, but in the same time it is able to achieve the desired economic intentions and architectural concepts.

Index Terms: competition, pavilion design, Normafa, park area development
Normafa and its surrounding are located on the Western outskirts of Buda. Most of the area is covered by forests. One can get to Normafa by various means of transportation. 2016 springs the council of Hegyvidék in Budapest advertise a competition for Normafa’s new pavilions. As time passes, the area became to a very famous and visited area. During one weekend more than 10.000. people are crossing here, winter and summer time as well. During the colt period Normafa is going to be a skiing area, and at the summer it is perfect for a tour. Nowadays the visitors has possibility to eat some special Hungarian food (like lángos, kürtöskalács) in Normafa during the trip. But the reason is the competition is, that every owner of a pavilion use different design, different ingredients, so it has no image design. In Normafa there is 6 different park area, where the new pavilions are needed. We created a group, and decided to design new pavilions for Normafa. The main idea of the conception was to create a modular „house”, what can strand by own, or it can be classified. The pavilions had to be flexible about the function, because some of them would be a small shop, and the other a cooking area, or just a shelter from the rain.

Index Terms: Vasarely, op-art, transformation, design, student work
On the occasion of the 650th anniversary of the University of Pécs, and the 110th anniversary of Victor Vasarely, Architecture Institute at the University of Pécs,: the Engineering Faculty have called the University students along with the University students of our international partners, for a common work. We were looking for projects of spatial experiments inspired by Vasarely, which were put in our present day world through a 'transformation'. We expected student ideas which represented visual thinking by Vasarely displayed in architectural spaces, form or structures in civil engineering, design works of art, urban design tissue or any other three-dimensional forms. The task was, for the imagined artwork, to prepare the reduced scale-model, with the aim to sense “cheating”, decorative three-dimensional visual work entertaining the human eyes and senses. We have received 75 applications, in topic Design Workshop, Special Constructions, Design of Building Structures, Art of Environment, Building Structure, Interior Design, Introduction of Architecture, Independent Studies. The presentation introduces the results of the multidisciplinary and international call, what has been summarized in a catalogue and in an exhibition made for the 12th Miklós Iványi PhD/DLA Symposium.

Index Terms: higher slip-joint connection, tangential stress, steel mast
Slip-joint connections are a relatively simple way of assembling high-rise steel masts in situ. Despite numerous advantages, these connections remain rather uncommon, owing partially to the absence of any methodology to determine their resistance. The presented paper concerns an experiment the aim of which was to examine how accurately it is possible to determine the tangential stress in a slip-joint using a simplified calculation. This calculation is also presented, and the results obtained from both these analyses are then compared to those from a FEM-based software.

Transformation of public space - Ante Starčević square in Osijek BRKANIĆ, Ivana*1 and KOŠKI, Željko* *
Department for Architecture and Urban Planning, Faculty of Civil Engineering Osijek, University Josip Juraj Strossmayer of Osijek, Osijek, Croatia
Index Terms: city centre, public space, Osijek, central square
A city needs public squares; they are the largest, most public rooms, that city has. And it is only these widened, swollen, public squares which can accommodate the public gathering, small crowds, festivities, bonfires, carnivals, speeches, dancing, shouting, mourning, which must have their place in the life of the city [1]. This statement shows us the most important function of the city centre: the function of gathering and interaction. Throughout the history, these activities took place at the Agora of the Greek polis, medieval towns markets and Renaissance and Baroque squares [2][3][4]. These wide and open places often maintained their function of the central city area until the mid-20th century. In the second half of the 20th century an image of the city was changed due to the development of information and telecommunication technologies, new forms of entertainment, the spread of consumerism and the commercialization of all walks of life. Nowadays, those open, public spaces at the city centre are replaced with closed, quasi-public [5] or pseudopublic [6], universal facilities which are privately owned - and whose main goal is consumption. City centre, especially its main square is no longer in a function of assembly of citizens instead, it remains the square only on the denotative level: through the square name [7]. It has become a place that has little to do with its original content; it is just a place of passage, the point where people gather to go somewhere else. The purpose of the conducted research is to investigate the role of the city centre in the 21st century. In a society where consumption remains almost only form of public interaction city outskirts with its shopping malls has replaced the downtown as a place for socialization and gatherings [8]. This trend, which exists in Western Europe and North America from the 1960s, in the southeast Europe took place at the turn of the 20th into the 21st century due to the political changes and delayed economic development. This paper shows the process of transformation of a traditional urban public centre on the example of the main square of Osijek's Upper Town – Ante Starčević Square.

Equivalent unique global and local initial imperfection – calculation procedure and discovered obstacles BRODNIANSKY, Ján*1 *
Faculty of Civil Engineering, Slovak University of Technology in Bratislava, Bratislava, Slovak Republic
Index Terms: imperfection, EUGLI, buckling, EN 1993-1-1, EN 1999-1-1 in clause 5.3.2 (11)
Equivalent unique global and local initial imperfection (EUGLI imperfection) is introduced in standards EN 1993-1-1, EN 1999-1-1 in clause 5.3.2 (11) and in Slovak national annex to EN 1993-1-1 NB.5. However approach described in these standards needs further explanation to fully understand its background to reduce possibility of causing errors. EUGLI imperfection and derived EUGLI imperfection method is based on obtaining amplitude for structural buckling mode, which can be than used as full-sized imperfection in assessment of structures loaded by combination of axial compression forces and bending moments. EUGLI imperfection was firstly used and introduced by prof. Eugen Chladný from Slovak University of Technology in Bratislava. The origin of this method was based on need of assessment of upper chords of open-deck truss bridges. The main idea of EUGLI imperfection method is described in detail by Prof. Eugen Chladný and Magdaléna Štujberová in paper in magazine Stahlbau vol.82. EUGLI imperfection method in mentioned standards and paper is designated for plane structures as are simple structural members or frame structures. In recent time approaches for members in 3D environment for FTB (flexural torsional buckling) and LTB (lateral torsional buckling) cases were introduced in Engineering Structures vol.96. These approaches move the possibility of EUGLI imperfection usage another step further. Presented paper describes use of the EUGLI imperfection method and developed computer program only on plane structures, however a computer program for line structures in 3D environment was developed too. During research in this field some obstacles, which have to be described were discovered and a solution for uncovered problems was proposed. As working example is presented arch with fixed (pinned) supports and with cross-section which changes along the structure loaded by transversal load with magnitude of 250kN/m. Whole calculation is performed in own built computer program with use of the EUGLI imperfection and 2nd order analysis.

Experimentally steered N2 method for soil-structure systems CEROVEČKI, Adriana*1, KRAUS, Ivan * and MORIĆ, Dragan* *
Department for Materials and Structures, Faculty of Civil Engineering Osijek, Osijek, Croatia
Index Terms: soil-structure interaction, N2 method, large-scale experiments
Design of economically justified and earthquake resistant structures is multidisciplinary and challenging task. Due to complexity in modelling and high computational costs it is often the case that soil – a vast medium that gives support to structures but also that transmits devastating vibrations – is neglected from analyses or is simply modelled using simplified discrete spring. The field of dynamic soil-structure interaction (SSI) is still vastly unexplored [1], while the root of its issues mostly lies in the fact that soilstructure systems – due to their pronounced nonlinearity and big appetite for parameters and variables – are still computationally very demanding. This is particularly a problem for engineering practice which looks for simple – yet safe and well tested – methods for analyses, as the deadlines are often very tight. The European N2 method [2] is coded performance-based design method for analysis of earthquake resistant structures. This method is simple and offers good results for structural design but, due to its novelty, engineering practice still does not recognize it. On the other end, this method is nowadays very much discussed in European high-quality journals (e.g. [3], [4]) and it is included in earthquake engineering lectures provided to graduate students. Nevertheless, this method still looks for testing and validation against experimental results, but also for improvements regarding including the SSI effects. Existing experiments [5] can provide good insight on seismic behaviour of real structures. Yet, these experiments have some shortcomings and disadvantages that cannot support improvements of the N2 method: (i) structures cannot undergo plastic deformations, which is an essential structural behaviour that governs the N2 method, (ii) contact pressure between the soil and foundation model is not realistic and (iii) it is not always easy to instrument small-scale models – clearly, only large-scale models can provide the most reliable and trustworthy results to support better understanding of behaviour of structures. A project recently started at the Faculty of Civil Engineering Osijek has an aim to eliminate the above mentioned shortcomings and to improve the N2 method. A set of large-scale soil-structure models with possibility of plastification of structural elements and well simulated bearing pressures will be conducted. The final outcome of the improved method will be safer urban environment with modern structures that will resist strong ground shaking.

Drainage channels are artificial multi-functional elements in the nature which have their own specific functions. The reason for building them up was the intensification of agricultural production and drainage of internal waters. Due to change of agricultural policy in Slovakia no attention for channels is foreseen. Primary and secondary channels although present significant connective landscape elements which can be used even for the opposite function – for artificial water supply of specific regions. One of them is the NATURA 2000 region of Tice stream in East Slovak Lowland. This article presents the evaluation of infiltration experiments in such channels for collecting input data for numerical modelling. Experiments were provided in Medzibodrožie region, specifically in the East Leles channel and Northern Rad channel. The methodology of experimental works in the field as well as some basic information about its evaluation are included.

Index Terms: 1763 Komárom earthquake, historical architecture, historical buildings survey, structural archetypes
The probabilistic estimation of historical earthquakes magnitude using fragility functions, alike the risk analysis of historical city centres, requires either the dynamic structural or the static pushover analysis of buildings, or Archetypes, characterizing the environment affected by those earthquakes. As most of these buildings no longer exist, the building-damage relation is difficult to achieve, only historical building surveys may hold the basis to generate structural archetypes befitting the analysis. In this paper, the historical survey of the city of Tata (Hungary) is assessed in order to develop the quantitative framework for the generation of historical archetypes to study the effects of the 1763 Komárom earthquake.

Index Terms: Building typology, thermal performance, building simulation.
Creating typology is a comparative method to investigate the physical or other characteristics of the built environment. It can be a useful instrument to facilitate the thermal performance assessment of existing buildings. Thermal mass and construction techniques play a significant role in thermal and energy performance of buildings. It is influenced by many factors, such as ambient weather conditions, building structure and HVAC systems. According to the annual report of the Kurdistan Ministry of Electricity and Energy (KMEE), the residential sector is the first electricity energy consumer during the past four years. 70% of the total energy consumption is generated by the residential building sector. This is an important indicator of the importance of residential building energy efficiency. For the purpose of precise assessing of energy performance of buildings, there is a need for accurate calculation and modelling tools. The study focused on analysing five types of residential buildings in the centre of the Sulaimani city (north of Iraq). The analysis is aimed to assess the energy performance of the building types and comparing results with dynamic analyses using IDA ICE 4.7.1 software. The results revealed that thermal performance of the buildings is mostly influenced by the variations of the construction techniques and materials.

The orientations of the existing elements of the built environment (adjacent buildings, existing spatial functions, roads) were the key factors in the placement of the new building. The public functions are placed on the North-East side of the lot. The free standing arrangement of the public facilities provides wide variety of spaces: closed and open external and internal spaces (external as farmer's market with fix boxes, sport fields, play grounds, event places and internal as offices and retails) The residential functions are placed at the West and South-West side of the planning area, in parallel with the South Mint Street, to take the best solar access. According to the project statement, a variety of different types of residential units allow for a heterogeneous community. In our plan we propose two different types of atrium (house with inner patio) and two types of two-story dwellings. The planning concept of the residential unites derive from the atrium arrangement. The atrium (inner patio) is the main frame: besides providing the intimity and protection it helps with good natural lighting and ventilation. Other positive effect is that the large windows expand the interior spaces and do not separate the users from each other. Two-story dwellings are cheaper and easier constructions with supplemented community spaces outside on the elevated community level (not public, used just by the dwellers). Beside the high density of 25 dwellings, the liveability is sure by good proportion of the inner and external spaces (community and public). The key element of the building is the cascade form, the stepped configuration of ""boxes"" that makes possible to have on 3 different levels with maximum sun. The atrium is faced to south, based on climate conditions – closing an angle with the South Mint street. The interior spaces of the atrium dwellings provide for the natural light and fresh air from the central patio. In summer it can be covered by shades, in winter could be protected by glass structures for adequate climate and to save energy (during Summer time this space can lower the temperature of the hot weather because of the deciduous trees, Winter the covered garden prewarm the cold air. The two-story blocks are oriented to North-East and South-West in order to be constantly ventilated and naturally lighted. The overlooking among apartments are minimalized with using less windows to outside, but the size and number can be increased with installing more green pergolas and green walls to increase the privacy.

The conservation system of historical cities in China and its comparison with European experiences DAN Ge*1 *

Index Terms: Conservation system, Historical city, Comparison
The conservation system of historical cities in China began in 1982, based on the consideration that “Focus on the overall situation of the city, strengthen the comprehensive protection of cultural relics”. Over the past 30 years, the conservation system has undergone some changes and developments. At the beginning of the establishment of conservation system, comprehensive conservation and emphasis protection are of equal importance. Since the 1990s, because of economic development and urban construction, the pressure of conservation has continued to increase, historical and cultural blocks became to the focus of urban conservation. After years of practice, the conservation system with three levels named historical city, historical block and cultural relic had been identified by the regulation documents. Since the 21st century, the view that protecting the historical district as a whole has gradually been concerned. A number of laws and regulations required delineation of the historical district, construction within the district should not adversely affect the cultural heritage and the historical feature. Compared the development of conservation system between Europe and China, there are different in many aspects, including the chronological order of value cognition and object recognition, the conservation target and the protection methods. The conservation of European cities is based on the expanding understand of value. The survey of historical buildings (group) provides information support for the understanding of historical regional aesthetics and environmental values. The attention of place spirit and multiculturalism caused that social development and economic rehabilitation and other issues were involved in the conservation of cities. The sustainable development perspective promotes broader urban conservation including awareness of city value as a whole and integration of heritage conservation and urban development. The stage of urban conservation in China is very different from European one. When learning from international experience, we can’t ignore the decades’ conservation foundation of European cities. In addition, while perfecting the conservation system of historical cities, it is necessary to strengthen the conservation of non-historical cities in China through urban planning.

Index Terms: housing application, public housing, European Union, renovation, homelessness
The aim of my doctoral research is to explore the social housing conditions at the beginning of 21st century in Pécs. I examine the characteristics of the era and of the city. The local proportion of social housing is currently 4-5%. This rate is higher than the country average but significantly lower than the European Union value. As up to now we have not had public data on housing applicants, we have been unable to describe what kind of flats are missing from the local public housing market. In order to rectify this unfortunate situation, I have created a digital database of over 2,000 housing applications of the county seat. With the help of this investigation we are now in a position to see more clearly the living conditions of people who are waiting for public housing, the number of minors in the families concerned, as well as their socio-economic conditions.

Index Terms: plate buckling, plate girders, multiple longitudinal stiffeners, experimental analysis, non-linear numerical analysis
The objective of this paper is to investigate the monotonic plate buckling stability behaviour of plate girder with multiple longitudinal stiffener. In order to characterize the static resistance and ductility of the system, an experimental programme is completed, varying the configuration and the applied loading, reflecting the fundamental buckling mechanism problems. The experiments also serve as the basis of further numerical model development. Numerical shell-element model is developed in Ansys software environment for non-linear finite element analyses, and validated through the comparison to experimental results. Parametric study is invoked to extend the results for a wide range of geometrical configuration. Static strength, ductility and failure mode are determined. The obtained resistance values are compared to the ones calculated by Eurocode 3, and the Eurocode method is assessed.

The essence of the application of the LCA study is to avoid increasing the quality of individual products and services at the expense of environmental degradation. LCA is regarded as a universal method that is useful for any organization, regardless of the nature and scope of business. We can determine the effectiveness of wastewater treatment and assess potential risks associated with operation of WWTP to the environment using appropriate methodology. The implementation of the method requires processing procedures are formalized, using exact methods, allowing to identify the environmental impacts on the environment. LCA is in industrialized and environmentally conscious states among ordinary tool of environmental management. The scientific part is the introduction of general standards for specific WWTP. The emphasis is on the correct understanding of the problem, regarding the definition of objectives, functional unit, system boundaries, and evaluation indicators. Based on the monitoring and measurement of pollutants in samples of wastewater, the data is processed by the competent LCA software.

Comparison of the MODFLOW modules for the simulation of the surface watercourse boundary condition DUŠEK, Petr*1 and VELÍSKOVÁ, Yvetta* * Institute
of Hydrology, Slovak Academy of Sciences, Bratislava, Slovak Republic
Index Terms: surface water, groundwater, interaction, numerical simulation, flow regime
Water table regime is an important factor for simulation of surface water – groundwater interaction. Stream water table elevation is influenced by the stream morphology, its width and depth, by obstacles, the amount of riverbed sediments and also by the volume of water flowing through the watercourse. In case of modelling interaction with time – dependent changes in surface water level or when there is no possibility to measure water table directly it is needed to create a simulation of surface water table regime as well. With integrated numerical simulations it is possible to directly compute surface water stages as a part of groundwater simulation, or a specialized software can be used to simulate surface water regime independently from the main groundwater numerical simulation. The aim of this paper is to compare these solutions for the three - dimensional numerical model MODFLOW (Harbaugh, et. al., 2000). There are three integrated modules that are used to represent the river boundary condition in the model. The modules are RIV (River) (McDonald, et. al., 1988), STR (Stream) (Harbaugh, et. al., 2000) a SFR (Streamflow – Routing) (Prudic, et. al., 2004). Simulation of the simplified theoretical aquifer and stream flowing through showed that the differences between the computed groundwater water tables are minimal amongst all three possible solutions. Modules STR and SFR are therefore equally usable as the more time-consuming process of coupling separate surface water regime simulation (HEC-RAS, MIKE SHE, etc.) and groundwater regime simulation. In more complex simulations it is recommended to use either separate simulation of surface water regime or the SFR module, where more complex parameters of the stream can be specified. The STR module is therefore not recommended for complex surface water regime simulation, because the characteristics of the stream are very simplified. Among the advantages of the SFR module is the possibility of simulating unsaturated flow below the stream, e. g. stream that is disconnected from the groundwater table in version SFR2 (Niswonger, et. al., 2010). This module is an integral component of the MODFLOW simulation and its graphical user interfaces.

Index Terms: small hydropower plant, pit-intake structure, water intake, hydraulic losses, velocity field
Intake structures with technology of small hydropower plants have a major impact on energy conversion and thus to achieve the designed parameters of the plants. The so-called pit-intake structures entered in to operation in the period after 1990 in Slovakia. They have intake reduced usually by vertical or slanted shaft unlike conventional water intake. These objects have been developed for small hydropower plants with larger gradients as an alternative to the classic intakes, which were too long, uneconomic respectively they were unable to build. However, it should be noted that many of these intakes have not satisfactory hydraulic parameters. This means lower performance of the plant and also losses in electricity generation. The paper deals with the identification of problems of flow in pit-intake structures and identification of tools intended to assess the homogeneity of the velocity field and its impact on the operation of the turbine.

Index Terms: Self compacting concrete, Air entrained admixture, Hardened properties
With the progress in self compacting concrete (SCC) application coupled with obligations for shorter construction periods, there is a necessity for further evaluation regarding applicability of predictive equations connected to mechanical properties. This research investigated the effect of air entrained admixtures on the mechanical response of SCC incorporating supplementary cementitious materials. Mixtures were arranged into two series: Control and air entrained series. Compressive strength, splitting tensile strength, static modulus of elasticity, surface hardness, ultrasonic pulse velocity and air void characteristics were conducted on 18 mixtures. Variable parameters were: water-binder ratio and supplementary cementitious materials. Yet water-powder ratio, cement type, SCMs content and aggregate particle size distribution were constant parameters. Based on the overall effect of air entrained admixture, results of air entrained SCC series revealed that the compressive strength, splitting tensile strength, modulus of elasticity, surface hardness and ultrasonic pulse velocity properties decreased in comparison with control mixtures. Further air void analysis justified such behaviour.

The development of the primary school is organized by the local government of Visegrád and the National Sport Centres. The currant buildings - the classrooms are in two buildings next to each other - can't fulfil the educational functions, there aren't enough places to learn and teach in a creative environment. One of the two parts is a beautiful historical building, but the other one is a small, later expansion. The aim of the development was to plan a new building with enough classrooms, specialized classrooms, teacher's room, interior and exterior public spaces. Our group suggested a contemporary building, which can fit in the historical downtown structure of Visegrád. We used durable, qualitative materials both in interior and exterior space. The inner and outer appearance of the building creates an organic unity. The various colours and graphical elements help the usage of the building and also makes children happy.

Index Terms: alternatives, process network, CPM, clothing manufacturer
The critical path method (CPM in short) is an algorithmic approach of scheduling a set of activities with known duration times and dependencies; CPM calculates the longest path of the planned activities. Used basically in the chemical industry, process network synthesis is an optimization methodology, which utilizes graph theoretical approaches and combinatorial techniques with a focus on the structure generation. This latter method handles the set of feasible solutions within one model and a single solution process. The current work focuses on a Hungarian clothing manufacturer's problem. First the industrial problem is presented, and its corresponding CPM graph is depicted. To answer all emerging questions, instead of solving cumbersomely a large number of CPM problems derived from the CPM graph, the CPM graph is transformed into a process network. As an advantage of this transformation, alternatives specified by mainly financial necessities as well as human resource constraints can now be easily managed, namely where specific activities can be performed in different ways by various employees having various qualifications, requiring different durations and obviously different costs can be considered within this model. A time optimal mathematical programming model is given for the process network with the alternatives, which model corresponds to the CPM problem. As further extension, the time optimal project plan with additional cost constraints mathematical programming model of the process network with the alternatives is also given. The present scientific contribution is dedicated to the 650th anniversary of the foundation of the University of Pécs, Hungary.

Index Terms: BIM; MEP Hanger; Revit
The building information modelling is the most developing part of the architecture. In many cases the modelling of the MEPF (Mechanical Electrical Plumbing Fire protection) systems take more time then the architectural part in the sector of commercial buildings. The hangers of the MEPF systems are really important part of the modelling because it takes a lot of time, consequently this has a big influence for the modelling costs. If we have to make a model of the MEPF systems with the hangers, than we can choose from two different modelling methods. The first method is to place the elements one by one manually. The second method is to use an add-on and place the elements “automatically”. The add-ons can be simple or complex, but unfortunately in case of complex we have less modifying possibilities to make changes in the functionality. The big issue is, how to make these add-ons more useful for the modelling process?

Geometric aspects of gothic architectural details – Methodological questions FEHÉR Krisztina*1 *
Department for History of Architecture and of Monuments, Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: Gothic Architecture, Geometry, Mesure, Survay
The quest for the secret of geometric design methods and proportioning strategies of medieval master builders dates back to the middle of the 19th century. The improvement of surveying technologies allows to adapt the advantages of laser-based instruments and computer aided analysis to the observation of this subject of revolving relevance. The examination of geometric principles on architectural details instead of whole building compositions this time, may provide more possibility to explore the original design conceptions, as the deformation of the ideal profile during the carving process is often negligible. The basic questions of my PhD research program are the medieval methodology of architectural design, the logic how geometry was used and the occurent regular patterns in the distribution of triangulation and quadratical methods of the surveyed profile collection. The main case study of the research is provided by the analysis of the remaining gothic construction elements of the Royal Castle of Buda (Budapest, Hungary) in the lapidarium of the Budapest History Museum. My intention is to expand our knowledge of this perished monument by identifying what role geometric proportioning played in the practice of designing the details. The specification of the relations between Hungarian and European medieval architecture is also one of the hopeful outcomes of the study as the presence of foreign master builders at the construction of Buda Castle is certified also by written sources. In the current status of the research my paper focuses on the methodological aspects of the surveying process of gothic architectural details. In order to find the most effective way to measure a representative amount of profiled stone samples, six methods have been tested on three elements of ribbed vaults and one element of a trumeau from medieval Buda Castle. Some results of this analysis are to be specified in the frame of my paper.

Index Terms: Test, Java, TDD
The connection between the production source code and the related unit tests is very strong. In some common cases, we might even consider this relationship as a duplication. One of the most important challenges however, in software development is to avoid duplications in order to keep the system maintainable. We researched the possibilities of automatic Java source code generation based on the specification provided by the associated unit tests. This possibility may seem far-fetched in the general case, but after considering the most common restrictions which are applied nowadays as best practice, it turns out that a significant part of the production code can be generated automatically. The goal is to generate viable implementations, which fulfil the requirements imposed by unit tests. According to our vision the modern test frameworks, development guidelines and computational capacities make it possible to reach this goal.

Index Terms: City and urban development, drainage and architecture, economical issues and environment protection, squares and public spaces, water and architecture
One of the most critical issues in the city of Pécs - in times of heavy rains – is the rain water rushing down the slopes of the Mecsek Mountains, which significantly affects the operation of the city, and, at times, seriously damage buildings and streets. In the actual situation, we have carried out an analysis on the reasons, whereby we can understand the points need changing and may set the necessary actions to be taken. The concept: to offer economic, ecological and aesthetic solutions to these problems which are also acceptable for the local residents. The concept includes the possible alternatives of the technical implementation, as well as the architectural means of the environmental planning concerned. We are presenting micro- and macro-environmental planning principles, which offer alternative solutions for both the immediate living environment as well as for public spaces. Let us take a closer look at the operation of the ""system"" conceived and the expected short-and longterm benefits of it.

Aerodynamic and energy optimized design of a Hungarian winery GANJALI BONJAR Mohammad Reza*1 and HÁBER István† *
Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary † Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: Building Aerodynamics, Energy Optimization, Hungarian Winery, Dynamic Thermal Simulations, CFD
In most common cases wineries are complicated building ensembles with high technical complexity. Integrating high level of architectural quality is always a challenge in such industrial design tasks, which can be further complicated through additional energy, climate and comfort questions during the planning process. In the frame work of a concrete contract for the implementation of a winery in Villány a complex, building physics simulations supported design process was carried out in order to combine both functional and aesthetical design aspects with energy, comfort and climate planning factors. In this way, beside climate and energy simulations also fluid mechanic calculations (CFD) could support the development of the first two design phases: the sketch and the approval plan. As result of the simulation supported process an optimum compromise was created that determines completely shape, form, building body, special organization, structures, materials, as well as building services systems. The paper describes the different sections of the design process with decision making simulation results.

Design of experiment – optimization of vitamin A HPLC analysis GARAI Lőrinc*1 *
Doctoral School of Multidisciplinary Engineering Sciences, Széchenyi István University, Győr, Hungary
Index Terms: Experimental Design; HPLC; Test optimization; Vitamin A
Among fat soluble vitamins, vitamin A is responsible for vision, as principal component of the function of cones and rods. Vitamin A has several intake sources, so its presence in several food types is be often characterized for quality control or research purposes. Selective analysis of vitamin A is mainly performed with high performance liquid chromatography. The native component can be easily tested due to its UV-absorbance and beneficial separation characteristics. To test the food sample, vitamin A has to be separated from the fatty part of food. This step is performed by saponification, which is the critical step of procedure due to the heat and light sensitivity of vitamin A. A Hungarian standard describing the protocol (MSZ EN 12823:1) recommends a wide range of temperature and time, giving an opportunity to optimize the recovery of the analyte. Experimental tests were performed from margarine sample to find the temperature and time settings for the best recovery. Both factors were examined with centered two-level factorial design. Trend analysis showed a tendency towards the corner points of highest possible temperature and shortest possible saponification time. Evaluation was made with Statistica and Matlab.

The European and the North-American urban fabric developed differently through the last centuries. The current cities in the United States have been suffering from many problems. The “new” needs of the human being, the new possibilities of the economic models and community-driven thinking has started the existing urban pattern to be changed for a more liveable and happy place. “Happy city”, “Inclusive city” or “Walkable city” are the new trends of the urban development. The new urban development era has a lot of incomprehensive results which provided many changes on the existing built environment. The research shows an overview about the trends of developments and the expected influences of the city scape. The scope of the research is generally the cities of U.S, with some detailed focus area on the capital of Colorado, the city of Denver, which is the second-fastest growing state in the U.S.

Index Terms: IDS, military, information operations, Internet, defence, cyberspace
In the 21st century wars are not limited only to land, sea, air and space. In the last two decades cyberspace has become the most important battlefield. The basic infrastructure of the modern world is the Internet, which is also a part of cyberspace. The Internet is connected to the military in many ways. First of all the Internet has its foundations in defence research and is literally an extension of a military network (ARPANET) built by the Department of Defence (DoD). From the military point of view, today's Internet is a strategic critical infrastructure. So many strategic systems are accessible through the Internet and threats can cause serious damage in our information based society. It requires consideration to adopt procedures from military science to make the Internet safe. The aim of this paper is to draw a parallel between military information operations and everyday defence of the Internet. Special focus will be taken on Intrusion Detection Systems.

Practical applicability of spark gaps in the high voltage grid HALÁSZ Bálint G. *1, KISS István* and NÉMETH Bálint* *
Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: Live line maintenance, portable protective air gap
The most important criteria for bare hand method during live line work is that the lineman must be at a safe distance and completely insulated from the parts of the line with different potential compared to the maintained wire. If the standardized clearances are not available in an exact arrangement, the live line work is not possible to be performed. To reduce these clearances, the magnitude of transient overvoltage have to be reduced. The solution for this task would be the use of portable protective air gap (PPAG), which works like a spark gap. The use of this protective equipment means there are two meaningful spark gaps at the same line: one is the PPAG and one is at the workplace. The aim of this paper is to show the importance of various overvoltage waveforms during the application this equipment in the described situation.

Index Terms: revitalization, reconstruction, rethink, cultural heritage
In many cases when an old building has to renovated or rebuilt due to new function, the question arises, should we or how much can we change and transform the original building. What is percentage of revitalization and when comes the point when its a brand new building hid behind the revitalization. What are the values of the building? Walls?? Use of materials? The architectural decoration? The colour of the walls? The room layout? The function of the rooms? The orientation? Proportions? etc. ... When you want to save in a building then it really will be saved or we permanently eliminate its real values. The answer for this question has been long argues by the restorers. But in case of a buildings conservation is not always a suitable solution. It may be appropriate for ruins, but for those buildings what’s basic primary function is to serve human and if they cannot then they lose their function, and because of the cost of maintaining the value of the property today in the developed western world's basic issue, it comes out that the building either will be demolishes or a new function has to be found. And then comes the question that a building which is functionally, morally obsolete, but we feel like it has architectural, artistic, historic value, how can we save, transform, revitalize, and which parts, values of the building has to be kept so we can say: “Yes, we saved this Building! We have saved our cultural heritage!”

Comparative analysis of housing estates road networks in Hungary HÁZNAGY Andor*1 and FI István* *
Department of Highway and Railway Engineering, Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: Street networks, Traffic modelling, Urban district, Network analysis
One of the mostly important challenge in urban design is planning an adequate street network, which is satisfying the daily demands of different transportation systems modes users. Understanding of nature of road networks has been a deeply studied problem for many years and extensive literature is now available. Important results have already been reached by papers specifically analysing the road networks of whole cities, or regions. However, the macro simulation of districts, or microdistricts of settlements are not so deeply studied. In the 1970’s and the 80’s lots of housing estates were built not only in Hungary, but also on every corner of Europe to handle housing shortage. Recently there is no basic rules for planning residential area due to the various shape of road network with different parking facilities in area of housing estates were used in the last decades. Therefore this paper is aimed at providing a contribution to the knowledge of comparing different neighbourhood road networks and identifying significant similarities and differences in these patterns. Five different micro-districts and their road network have been analysed in Budapest. The criterions for selecting of micro-districts are the following: (i) districts were built in 1980’s, (ii) boundary roads are situated around the analysed microdistricts, (iii) they have different layouts. The last one was important to obtain some similarities in different networks. During the field survey the efficiency of both traffics calming and parking facilities, as well as the dimensions of cross sections are measured. The streets are characterized by these data and they are making them unique. Next to topological investigation, which contains the statistical analysis of streets and intersections, the road networks based on microscopic traffic modelling are also analysed. In this work, we not only the current states were analysed but also other 8 versions were deeply studied in every case. The differences between versions are in the following parameters: turning impedances, applied velocity and the capacity of internal links. By comparing the results of various shaped microdistricts, we get a highly detailed picture about both the differences in their layouts and traffic affairs, which are resulted by both the different concepts of theoretical design schools and the number of connections as well as the position of the connecting high capacity roads. On the other hand, by comparing the results obtained from the distribution of length of street networks, numbers of intersections and number of parking vehicles we are able to highlight inconsistencies, organizational problems and point out which are the most sensitive routes and intersections of the network.

Searching for accident black spots with accident analysis software 'Webbal' and GIS software based on the GPS coordinates HEGYI Pál*1 *
Department of Transport Infrastructure, Széchenyi István University, Győr, Hungary
Index Terms: Accident analysis, Geographic information system, Heatmap, Road network
There are several methods for the analysis of road network’s accidents. In Hungary from 2011 GPS coordinates are used to identify the location of personal injury accidents. This method significantly improves the display of locations of accidents on the map. They are analysed using GIS tools. Accident black spots are the most dangerous places on the road network. They are identified by the density of the accidents on the network. One of the methods is the accident density searching. The used methods and algorithms in some software may show differences in relation to one another. In my research the local road network in some Hungarian settlement were investigated. The analysis was made using WEBBAL accident analysis software and QGIS software. The results are visualized accident density plots and heatmaps.

Algeria; North African country, hides between the line of its past, a great diversity of historical influences; from the ancient discoveries, to the roman monumentality, passing by the ottoman and Islamic luxury , and finally arriving to the prestigious French architecture. Today, the Algerian national heritage is at risk, and a significant number of its monuments are endangered, while many buildings of great value, are abandoned, forgotten and unrecognizable. One of these monuments is the villa of “Clare Consuelo Sheridan”, an English artist, sculptress, novelist, and cousin of Winston Churchill , during the 1920s and 1930s, she spent altogether 8 years near Biskra, the Gate of the Sahara; an oasis town in French Algeria. With Arabisance style and local architecture, the Sheridan Villa, Stands as a living testimony of Clare’s experience in the Algerian desert, but unfortunately the house, is in a very bad conservative state; major parts have fallen down, and now abandoned by its owners. After a long period of historical, architectural and constructive assessment, and in the intention of protecting this monument, we suggested an intervention project defined under the title of: "the rehabilitation of the villa Sheridan into an artistic residency", to help revalue this unique architecture, and adapt it to needs of modern life, so it can be transmitted to future generations in a better condition.

The paper deals with the analysis of hydraulic processes in the object sedimentation tank. While we are solved this research work had been carried out on the object sedimentation tank WWTP Nitra 2 series verification measurements. During the verification measurement parameters were measured: the speed in the direction of waste water flow rate of the waste water in a direction perpendicular to the flow rate and the concentration of suspended solids. In total, these parameters were measured at 400 points, and authentication parameters were subsequently included in the verification of a mathematical model. Article is analysed the influence of the in-flow zone on the flow patterns. The analysis was carried out by means of mathematical modelling in ANSYS FLUENT software. The simulations were based on the model of the flow in an existing tank created by design drawings and verified by verification measurements. Simulations were created in the application of various structural modifications to optimize operation. An analysis solutions building modifications have been identified as the most suitable method of removing structural modifications the bottom internal deflector along with a placement the horizontal deflector. In this type of simulations the flow speeds on the bottom of the tank are displayed very low to negligible - the maximum speed 0.008 mm / s.

Low frequency noise emission of lighting systems ISTÓK Róbert*1 *
Power System Department, Kandó Kálmán Faculty of Electrical Engineering, Óbuda University, Budapest, Hungary
Index Terms: THD, CFL, induction, lamp harmonics emission, harmonic filter
The main task of this paper is to examine the modern lamps from harmonics emission point of view. The modern lighting lamps are nonlinear loads, and introduce harmonic distortion in power supply lines. The main source of harmonics is the rectifier stage from electronic ballast. In conformity with standard requirements the emission measurements are done for a single lamp during the validation process. In real life more than one lamp are used at the same time in a system. In Fig. 1. is presented the THD – total harmonic distortion emission measurement result of different CFL - compact fluorescent lamps number. Increasing the number of measured lamps produce a THD decrease. The explanation of the phenomena is that the inductivity of circuit is increasing which produce harmonic filtration. In Fig. 2. is presented the THD measurement results of induction lamps. In this case the decrease of THD is more accentuated as in case of CFL. In Fig. 3 is presented the THD measurement emission of CFL lamps and an incandescent lamp too. The THD emission is much lower than in first two case. That is not a result of better filtering done by incandescent lamp. The answer are coming from THD definition. THD is defined as the ratio of the r.m.s value of the sum of harmonic components to the r.m.s value of the fundamental component. The fundamental components of the incandescent lamps is more higher than the fundamental and the harmonic emission of the CFL lamps. The circuit with 2 and 3 CFL and an incandescent lamp have a higher THD emission because the inductivity of the incandescent lamp which is between line and neutral wire reduce the inductivity of the circuit. The THD is lower but the harmonics emissions have the same level as in case when we do not have incandescent lamp in measurement circuit. Total harmonic emission in a circuit with more lamps decrease comparison to a single lamp emission because in circuit appear a filtering phenomenon.

Index Terms: Revitalization, Prizren, system of channels, “Jaze”, restoration, integration
The city of Prizren is one of the oldest settlements in Kosovo and in the Eastern Europe, located in the middle of the ancient Venice-Istanbul road, which has always been a crossroad of trade for the whole region. It used to be called ""Venice of Balkans"" thanks to its sophisticated system of channels that used to have, so-called “Jaze”, which were branched from the river and were scattered throughout the neighbourhoods of the city, and further the channels were branched into smaller channels, which have carried water throe small public streets to each house in Prizren. The aim of this study is to research the role, function and value of this channels system in the city life of Prizren, and whether these channels can be functionalized and restored for today’s needs. The methodology used is based on analysis, interviews and evaluation method. This study will attempt to present the social, economic, spatial and environmental values of the revitalization of this channels system in the city of Prizren and the importance of its restoration and integration into today’s modern life. Finally, it will give some suggestions for the principles and strategies how to achieve these goals.

Index Terms: glass, columns, stiffness of fixing, coupling parameter, stability
The design methods of the load bearing glass columns developed extremely in the last years. This development strengthens our confidence in the glass as a construction material. Our generation is still not accustomed to the transparency of construction materials, it can be seen if we step on a glass roof, glass bridge and there is a deep abyss under our feet. Numerous glass researchers have been trying to optimize the glass structures in terms of cost-effectiveness and safety in the last years. The authors carried out several laboratory experiments to analyse the key factors of the glass column design. Important influencing factors are investigated in the present article such as the influence of the fixing at the end of the glass columns which essentially modifies the load bearing capacity of structures. The efficiency of the gluing of the interlayer foil between the glass layers was analysed based on the individual laboratory experiments, in which the classical coupling parameter was investigated. The stress distribution is not taken into account in case of the laminated glass structures at the long term designing. However, engineers apply the residual capacity of the laminated glasses at the construction design. New interlayer foils and lamination technologies will appear in the near future where the stress distribution cannot be neglected in case of the durable design of structures.

Regardless on scenarios of climate changes and the attempt of their mitigation, climate changes will impact the access to natural sources (water and soil) what will lead in some regions into significant changes of conditions especially for agricultural production. One of these regions is the territory of Zemplin. The contribution deals with possibilities of the adaptation strategy in given region to prevent against floods and drought, as well. The main role in prevention is given on existing drainage channel system and its water level regime in lowland conditions. Very important seems to be the operation on pumping stations which are built in end profile of drainage systems. Example of such operation and its results are presented in the paper, as well.

Index Terms: design thinking, visual culture, green future
Our well-practiced existing solutions and habits don’t seem to help imagining a beautiful future. We live in a fast paced over-populated world. We hardly devote any time for ourselves and for our children. Besides our daily rat-race lifestyle we have limited time to understand ourselves and our environment. Therefore today it’s easier to „get lost” in our world as individuals than it ever was ever before. Due to our materialistic way of thinking we tend to focus too much on the physical conditions distracting attention away from our spiritual development. We have to work to make a living and our brain is focused on material goods. We have a great planet to live on, continuously developing technologies, knowledge based on the past from which we can learn from. But we have to slow down and even stop for a moment to give ourselves time to rethink. We have to look around and see how truly rich we are. Luckily we are capable of turning things in a good direction and define the next steps for our future. So dare to think outside the box! I believe in the power of family. In my architectural practice I try to help to create a physically and mentally healthy environment for that small building block of society.

In Kosovo, originality often meant leftovers inherited from other cultures during centuries of invasion and dominance under the Ottoman Empire. Considering the multinational and multicultural character of Kosovan society and its diversity of religions, Roman Catholic and Orthodox religious buildings cannot be disregarded either. The respect for tradition and the existing environment, including architecture, are details to be considered. In this context, the National and University Library could and should be considered a valuable example for the years of general transformation in Prishtina and in all of Kosovo. Even with all the contemporary way of thinking, the traditions, the religion and other regional aspects were not entirely disregarded, especially in the case of the Library building.

Every individual should have the right to a standard of living but due to certain factors or unforeseen circumstances the right to a decent home has been denied to certain individuals. Certain factors such as natural disasters, migration, inequality, high cost and security have contributed to informal and substandard settlements in Nigeria. Many residential structures in rural communities in Nigeria are built from mud but these buildings tend not to last long since they are not properly protected from the weather. The environment has always blessed us with abundant natural resources that could be tapped easily and used to meet human basic needs if the proper building techniques are applied but in Nigeria, local or low tech materials are generally perceived as architecture for the poor. In Nigeria, earth, stone, bamboo, straw and wood are common materials that could be sourced for in different parts of the country. Looking at the works of Diebedo Francis Kere (school Gando), with architecture one can provide a conducive environment with available natural and renewable resources. Also, works of Shigeru Ban, where he uses architecture to help those in need, by creating fast, economical, and sustainable buildings. My aim is to see how locally available materials could be used to create a safe and conducive structures within the shortest time and least amount of resources.

Assessing stream water quality influenced by storm overflows from sewers JULÍNEK, Tomáš*1 and ŘÍHA, Jaromír* *
Institute of Water Structures, Brno University of Technology, Brno, Czech Republic
Index Terms:
For open channels significant pollution sources during the intensive precipitations are outflows from stormwater overflows on the sewer network. When combined with low discharges in rivers, the water released from overflows can cause high concentration of pollution in receiving open channels. In this paper, the results of computer modelling of the impact of sewer network overflows on the stream water quality in three municipalities, namely the cities of Brno, Vyškov and Kuřim (Czech Republic) are shown. The local river networks are the main receivers in the cities where storm water overflows are orificed. The design rainfall events and the design scenarios, such as the location and parameters of stormwater overflows, were set up by the designers of the sewer system. The assessment of the impact of the pollution released from overflows shows that during the storm event the immission water quality standards are exceeded by several times for certain time period. The results serve as a base for the discussion and proposals on the measures, improvements and structural modifications on the sewer network for three mentioned localities. The effect of such proposed arrangements is demonstrated for the Brno and Vyškov open channel systems.

Vulnerability, safety and response of nuclear power plants to the hydroclimatic hazards KATONA Tamás János* and VILIMI András†1 *University
†MVM
of Pécs, Pécs, Hungary Nuclear Power Plant Paks Ltd, Paks, Hungary
Index Terms: nuclear power plant, vulnerability, safety, hydro-meteorological extremes, climate change
The Great Tohoku Earthquake and Tsunami, and the severe accident at Fukushima Dai-ichi nuclear power plant 2011 alerted the nuclear industry to danger of extreme rare natural hazards. The subsequent ""stress tests"" performed by the nuclear industry in Europe and all over the world identifies the nuclear power plant (NPP) vulnerabilities and define the measures for increasing the plant safety. According to the international practice of nuclear safety regulations, the cumulative core damage frequency for NPPs has to be 10-5/a, and the cumulative frequency of early large release has to be 10-6/a. In case of operating plants these annual probabilities can be little higher, but the licensees are obliged to implement all reasonable practicable measures for increasing the plant safety. For achieving the required level of safety, design basis of NPPs for natural hazards has to be defined at the 10-4/a ⎯10-5/a levels of annual exceedance probability. Tornado hazard is some kind of exception, e.g., the design basis annual probability for tornado in the US is equal to 10-7/a. Design of the NPPs shall provide for an adequate margin to protect items ultimately necessary to prevent large or early radioactive releases in the event of levels of natural hazards exceeding those to be considered for design. The plant safety has to be reviewed for accounting the changes of the environmental conditions and natural hazards in case of necessity, but as minimum every ten years in the frame of periodic safety reviews. Long-term forecast of environmental conditions and hazards has to be accounted for in the periodic safety reviews. Changes of the frequency and intensity storms, tornadoes, river floods, flash floods, extreme temperatures and droughts affect the operability and efficiency as well as the safety of the NPPs. Response to extreme hydroclimatic events depends on the features of particular hazards, e.g., predictability, possibility and time available for the protective actions, potential for causing cliff-edge effects and the possible combinations of events. Effective protection against the adverse effects of the hydroclimatic extremes can be ensured by proper definition of the design basis that compensate the potential changes of the extreme values and their frequencies due to climate change. In the presentation the vulnerability of the NPPs with respect of hydroclimatic extremes will be analysed. The consideration in the presentation will be illustrated by the case of Paks Nuclear Power Plant, Hungary.

Index Terms: BIM, IMPLEMENTATION, DESIGN, DSDC, CONSTRUCTION
The second phase of my research is about the compliance test of the first corporate level regulation of building information modelling in Hungary, in which creation I participated during the first phase. The form of the test result will be a case study evaluation and the regulation will be modified based on the consequences. The corporation who ordered the regulation is one of the biggest constructors in Hungary and usually has large projects with short deadlines to build. Nowadays it often happens that the execution planning and the construction of a building is merging together, causing the failure of the interaction between the conventional design and construction management procedures and the BIM workflow, in various ways. The normal project planning and managing solutions are insufficient recently, new basic principles needs to be developed. In the presentation the project environment of the case study and the main uses and benefits of the BIM based design will be introduced, including the difficulties of the managing tasks.

Parametric study of sway buckling influence for portal frames with laced built-up members KOVAČ, Michal*1 and VANÍK, Zsuzsanna* *
Department of Steel and Timber Structures, Faculty of Civil Engineering, Slovak University of Technology in Bratislava, Slovak Republic
Index Terms: portal frames, laced built-up members, sway imperfection, in-plane buckling
For the portal frames sensitive to buckling in a sway mode the second order effects with the initial sway imperfection should be taken into account. In the portal frames with the laced built-up columns, the additional sway deformation due to the second order effects causes additional axial forces in the chords. Besides creation of sway imperfect structure and the second order theory calculation with any commercial FEA softwares a simplified method is convenient for praxis. The adaptation of the norm procedure for stability check of the individual laced compression members, located in the clause 6.4.2 of norm EN 1993-1-1, could be used to quantifying the additional axial forces. In such case the buckling length of the columns according to the global buckling mode of an equivalent frame structure will be used as the length of an equivalent laced compression member (Fig.1). This equivalent laced compression member will be checked by the mentioned norm procedure. This simplified method was verified in previous papers of authors. Using this simplified method the parametric study of portal frames with laced built-up members was performed. The differences between utilizations by two methods are the subject of the parametric study. The first one is the simplified method accounting both the sway imperfection and the bow imperfection between nodes. The second one is the equivalent column method accounting only the bow imperfection between chord nodes. The various non-dimensional chord slenderness to non-dimensional column slenderness ratios were considered. ACKNOWLEDGEMENTS This paper was supported by the research project for excellent teams of young researchers of the SUT in Bratislava, Faculty of Civil Engineering.

Ottoman funeral architecture in Hungary – General features and specific questions of present restoration projects KOVÁCS Máté Gergő*1 *
Department for Architectural History and of Monuments, Faculty of Architecture, Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: Ottoman architecture, türbe, architectural history, preservation of monuments
During the 15th and 16th centuries the central territory of the Hungarian Kingdom was occupied by the Ottoman Empire, which has resulted the norths examples of the Ottoman building culture in a cultural environment which has been framed by the Christianity. Many of these buildings were damaged after the Ottoman era and the function and shape of the remained ones have been modified during the last centuries. During the 20th century the preservation and conservation works of these monuments have been started, since the relationship of the late Ottoman Empire, and the early Republic of Turkey became better. This process has a flourishing revival in the contemporary years: in 2010, as a symbolical gesture, the Cultural Capital of Europe was the Hungarian city of Pécs and Istanbul at the same time: two cities with different past and scale but same multicultural and multi-ethnical life with Christian and Islamic roots. This process is still in progress: the two successor state of the formerly occupied Christian Kingdom and Islamic Empire has an outstanding and exemplary cooperation in the preservation and restoration works of Islamic sacral heritage in Hungary – within the border of the European Union. In these years, a unique group of the Ottoman architecture in the territory of Hungary are under conservation and restoration: these are the funeral buildings, the so called ’türbe’s. This presentation summarizes the questions of the present restoration works of this type of buildings in Budapest and Pécs, and also situates it in a wider context – the general features of the architecture of ’türbe’s.

Index Terms: built heritage, migration, multiculturalism
Hungary’s history is characterised by a series of migrations, which resulted in the long term coexistence of different cultures. This coexistence has left its mark on our built heritage. One can observe the adoption of architectural motifs and ideas, as well as specific buildings among ethnic groups, and their integration into our collective heritage. Migration and multiculturalism are controversial topics of our day, the former setting a challenge to society in recent years, the latter being a continuous phenomenon in some places. What are architectural society’s responsibilities and what instruments can it call upon in these circumstances?

Dynamic office building design KŐVÁRI Gábor*1, and KISTELEGDI István* * Faculty
of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: Energy design, office building design, flexible spaces, dynamic buildings, new and existing offices
We are building too big office buildings. Way too big. Then we spend money, energy and time in a traffic jam every morning and afternoon, frustrating ourselves, just to commute between this office building and our home. Newer and newer building materials are introduced to reduce the heat loss of our buildings. More complex building management systems are designed to increase the energy efficiency of these buildings. Although these new materials and management systems are far more expensive than the previous ones, only a few percent decrease of energy consumption can be achieved. In addition to the development of the materials and structures we cannot avoid to rethink the utilization of our office buildings. Employees can have the opportunity to decide when they would like to work in the office or at home. By using their personal smart devices to book office or meeting spaces, their calendar can be connected to the building management system, which can calculate the actual, overall demand for comfort spaces. This method can be applied for both existing and future offices. In the case of existing buildings, only occupied spaces should be operated at comfort level values. Meanwhile unused spaces of the building can stay in “stand by” mode, at minimum tempered level or can be rented out for short term users. When planning a new office, we have two options: a much smaller building can be considered for the same amount of tenants by granting office space only for a certain percent of employees and the rest should work from home office; slightly bigger buildings ensure huge flexibility to serve different needs of comfort spaces.

Classification of industrial brownfield areas LONČAR, Lucija*1 * Department

Index Terms: brownfield, industrial brownfield, classification, CLARINET, CABERNET
Abandoned industrial and commercial sites known as brownfield was recognized two decades ago. There is no certain definition of the term brownfield and at the same time many languages either do not have term or simply adopt the English word. The purpose of this paper is threefold; (1) to provide insight into the definition and classification of brownfield areas, (2) to show the working group dealing with the renewal of brownfield sites and (3) to identify relationship between classification of brownfield sites and successful redevelopment brownfield sites. The term brownfield was first used in the United States in 1992[1]. According to United States Environmental Protection Agency (U.S. EPA) brownfield site means real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant [2]. European definition of the brownfield term according to working group CABERNET, building on CLARINET, defines brownfield sites as sites that have been affected by the former uses of the site and surrounding land, are derelict or underused, may have real or perceived contamination problems, are mainly in developed urban areas, require intervention to bring them back to beneficial use. Brownfield areas commonly found in city centres in attractive locations and they often provide the identity of the place and talk about the history of the site. Parallel to these areas pollute the city because they are no longer used, but because of their previous purpose behind them remained contaminated and polluted soil. According to location in the urban tissue are characteristic three divisions of the brownfield sites in the central area (city centre), on the border of the city and the historical zones. According to the purpose are divided into: industrial zones, military complexes, surface mining, railway complexes, coastal areas and facilities of public city services. Conforming to U.S. EPA brownfield sites classified as potential pollutants environment: oil installations, manufacture, storage (recycling), facilities for treatment and recovery and other [3].

Urban typology: Pre- and post-compromise urban types LOVRA Éva*1 *
Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: urban typology, Compromise, urban planning, Dual Monarchy
In the pre industrial period in the territory of the former Hungarian Kingdom, two urban development archetypes can be distinguished, which were defined by their geographical characteristics and adapted to the Western and Eastern urban planning traditions. In contrast, the industrial revolution and other city-creating forces in the period between 1867 - 1918 led to variability of urban structures. In the pre-compromise (1867) era, the definition of the urban tissue in the studied territory was followed and strongly influenced by the landscape features and referred to the local character of the territory (building materials, spreading structure, wide streets). Since economic and historical changes have followed the compromise between the Hungarian Kingdom and the Austrian Empire (1867), as a result of it and the upcoming industrial revolution a progressive urban development started and it was determined by new urban pattern, different city construction, urban fabric and urban types. The new urban forms and organisation require new urban tissue and urban typology. Taxonomy purpose of the study is to systemize the new urban tissue types, which development was influenced by the progressive urbanization, and by further organization and combination of these types define a new urban typology of the cities in the Dual Monarchy.

Analyzing the requirements and the solutions for a point cloud based BIM model MÁDER Patrik *1, ZAGORÁCZ Márk* and RÁK Olivér* *
Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: BIM, point cloud, requirements, solutions
The rapid development of the information technology has huge impact also on construction industry. It is tempting to speculate that the generation of point clouds (from laser-scanning or photogrammetry) and the Building Information Modelling (BIM) are the two most evolving concepts which are used many times together in architectural projects. As a side effect of the fast technical evolution, many clients, who are ready to implement the new inventory to the daily processes without clarifying their real needs, have an increasing but unaffordable expectation to the specialists. It results that the well trained experts need to give assistance and guideline right from the beginning of the project besides explaining that the new tool does not equal a magic button which generates the desired result in a moment. This kind of “free” help is necessary for both parties to find a balance between the requested and reasonable outcomes of the project and keep the market trusting in the employed technologies. Some examples of the developed and tested guides will be also displayed in the presentation.

Index Terms: building design, renovation, modernization, educational institutions, kindergarten, nursery, design guidelines
The first few years of life, the early childhood strongly determines one’s social skills, the ability and desire to learn and acquire new knowledge. In addition to providing a physical space for education, nurseries and kindergartens have a strong impact on the development of young children. Examining the sensitive relationship between architecture, buildings, and children, my presentation is going to discuss some important issues of building design through real-life projects. I am going to explore the design of a feasible institution from an existing building through functional change, the characteristics that can be considered as risk factors, the design guidelines and milestones concerning this specific project. I am presenting an ""ideal state"", taking the children's needs and viewpoints into account. By comparing the ""ideal"" and the planned states, the main theses for the related schooling-, educational institutions can be formulated. I am also going to investigate the issues of how to fit in the town structure, the green areas, the establishment of playgrounds, functional relationships, and regulation policies. Today, in addition to the construction of new educational buildings, the renovation, modernization and extension of the existing stock of buildings in order to meet the current requirements has become a topical issue. Through the project presented, the difficulties of renovation, conversion and the related cost issues are also going to be explored. Any design supporting the children's physical and psychological development can present new design trends and segments in architecture, with special regard to the fact that the future is based on their health.

Numerical analysis of cold-formed steel shear wall panels subjected to cyclic loading MEDDAH, Hiba*1, BEREDIAF-BOURAHLA, Malika* and BOURAHLA, Nouredine* *
National Center of Applied Research on Earthquake Engineering (CGS) & Blida University, Algeria
Index Terms: Cold-formed steel, cyclic loading, modelling technique, nonlinear analysis, shear wall panel.
Shear walls made of cold formed steel are used as lateral force resisting components in residential and low-rise commercial and industrial constructions. The seismic design analysis of such structures is often complex due to the slenderness of members and their instability prevalence. In this context, a simplified modelling technique across the panel is proposed by using the finite element method. The approach is based on idealizing the whole panel by a nonlinear shear link element which reflects its shear behaviour connected to rigid body elements which transmit the forces to the end elements (studs) that resist the tension and the compression. The numerical model of the shear wall panel was subjected to cyclic loads in order to evaluate the seismic performance of the structure in terms of lateral displacement and energy dissipation capacity. In order to validate this model, the numerical results were compared with those from literature tests. This modelling technique is particularly useful for the design of cold formed steel structures where the shear forces in each panel and the axial forces in the studs can be obtained using spectrum analysis.

The impact of the formal and the construction choices on the climatic performance of the façades MESSAOUDA, Rais*1 * Breuer
Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: Facade, climate performance, formal choices, constructive choices, hot and dry climate
The rational combination between the formal and the material aspects to design efficient facades in the point of view of climate performance, is an important decision in the process of architectural design, and it is due to the inherent complexity of both aspects, and the challenge to reconcile instead of opposing them. This research aims to test and evaluate the impact of formal and constructive choices, and to examine until what point the material choice rationalize and release the formal architectural decisions ; in the perspective of a climate performance approach of the building. To explore this issue, the study is based on experimental approach, through the development of a reference model that gave place to the creation of three building matrices reflecting the possible combinations of material and formal variables. These matrices generated (36) suspected variants of facades. On the basis of these three matrices, the parametric study was conducted; three series of tests by simulation were effectuated, by the software Ecotect (V5.5), Radiance (2.0 BTEA). The Parametric analysis was used to evaluate the climate efficiency of the façade , by testing different scenarios of the interaction between the formal and material dimensions; characterized by the type of material, the ratio of openings and the presence of projections. The impact of materials, porosity (ratio of openings) and solar protection by decrochments and the efficiency of heat and light behaviour were studied. This allowed to test the hypothesis of departure and to determine the best combination of the variables selected.

Questions of 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, structure, interpretation
For a student of architecture it is essential to get to know the history of architecture. Interpretation of the architectural form and structure can be used as a guide in order to understand the built environment. The human body, the social circumstances and the heritage are all influencing the way how somebody starts to look at a certain built object. Many famous buildings seem to be uninteresting or just representing the dream of the architect for the first look. After understanding the architectural concept or knowing the reason of the final form even those buildings can turn to be special or unique. Aim of this presentation is to enlighten some of the most important questions of the interpretation of architectural form and structure by presenting important and famous buildings from the history of architecture.

Index Terms: ultrashor pulses, free-electron laser, electron bunch, undulator
The generation of coherent, high intensity, ultrashort pulses in the Angstrom wavelength region is a very important goal in scientific research projects and it opens up new frontiers across many parts of science (biology- a look inside materials, chemistry – motions in molecules, physics – motion of the electrons, etc.). High energy electrons generated by particle accelerators are used in synchrotron beamsources (3rd generation light sources) or Free Electron Lasers (FEL). Nowadays FELs are the most brilliant light sources in the X-ray regime (XFEL – 4th generation light sources) with high pulse energy, short duration. The basic principle of FEL can be described through the generation of synchrotron radiation, where electrons with relativistic velocity go through a periodic lattice of alternating magnetic dipolar fields - so called undulator (where the undulator parameter K<1) or wiggler (K>1). Electrons are accelerated in the direction transverse to their propagation due to the Lorentz force introduced by the undulator’s magnetic field. Electrons emit electromagnetic radiation which wavelength (or frequency) can be controlled by the undulator parameter and the energy of the electronbunch (resonant wavelength). Several types of construction have been developed in the last decades. In the 1970s were free electron laser oscillators with feedback mirrors (law-gain FELs) in the 1980s Self Amplified Spontaneous Emission (SASE) FELs without mirrors (single pass FELs). In SASE the radiation generated by spontaneous emission modulates some electrons in the electronbunch, so the wake radiation can react to the e-bunches and generate so called microbunches. Due to microbunching the intensity of the wake radiation can be raised along the hundreds of meters long undulator. The wavelength of the SASE generated pulses reach the range of Angstrom, the length of the pulse is a few femtoseconds, the power is in GW. Thanks to the development of lasers, manipulation with lasers can be obtained (seed laser) and these settings can contain a modulator undulator for electron manipulation and a radiator undulator for producing radiation and other special component like chicane, quadrupoles, etc. which ones we can also produce microbunching with. These setups call HGHG (High Gain Harmonic Generation) FEL and EEHG (Echo Enabled Harmonic Generation) FEL. Even shorter pulses (attosecond) are proposed based on theoretical calculations and simulations, but these methods are under development. I make calculations and simulations of these constructions with a special 3D time-dependent simulation code Genesis 1.3.

Localized basis structure and causality relationship of the planar mirror optical waveguide NYITRAY Gergely*1 *
Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: waveguides, electromagnetic wave-propagation, diffraction
All physically realizable optical waves have finite dimensions, however the eigenmode description of optical waveguides based on unlocalized plane wave components. Unfortunately this useful model makes no difference between short and long waveguides hence the causality relationship could not read out from it, however it has some inherent causality aspect. We present a gedanken experiment associated with a planar mirror waveguide problem which specify the degree of localization of the eigenmodes in the transverse direction. Fig. 1. shows the transverse electric field distribution of a localized basis element of the planar mirror waveguide. The localized wave components are causal, observable and realizable.

PV System Auto-Sizing with Batter Energy Storage Based on GPS Coordinates OLASZI Bálint Dávid*1and LADÁNYI József* *
Department of Electric Power Engineering, Power System and Environment group, Faculty of Electric Engineering, Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: Renewable Energy, PV Systems, Convex Optimization, Shading Calculation, Economic optimization
The paper presents a PV system auto sizing algorithm with irradiance and shading calculation using the PVGIS database. Based on measurement data, monthly irradiance correction matrixes are simulated to completely describe the yearly irradiance loss caused by shading of the nearby objects. As result, a function between the shaded area and the yearly energy loss can be obtained. Furthermore, PV modules can be autoallocated on a given area according to the boundary conditions. Taking into consideration the PV installers pricing system, a complete PV auto-sizing algorithm can be presented which greatly reduces the time spent on quotation writing. The paper includes a Battery Energy Storage Sizing algorithm according to the given economic conditions which extends the capability of the PV system auto-sizing algorithm.

University of Applied Sciences Burgenland, Eisenstadt, Austria
Index Terms: talent management concepts, matching algorithms, meta model
Standardized as well as semi-standardized – so called reference models – management concepts have been developed in the last decades promising economic growth or higher efficiency for organizations. Typically, these concepts like ITIL, COBIT, BPMM, etc. are implemented either for the IT department or for the organizational department, sometimes in an ordered manner, sometimes by incident. This paper will address the semi-formal description of the two selected concepts ITIL and COBIT and abstract common and excluding issues with matching algorithms in order to create a comprehensive methodology to strengthen strategic management from both organizational forces, IT and operations. This methodology will lead to the derivation of a meta model with the aim in conducting tailored consulting to best serve organizational needs.

The effect of the connention between industrial floor and bedding course on the tensile strength PAPP Dávid*1 *
Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: Shrinkage, deformation, friction, material model
Prevention of cracks cause still remains one of the main problems for designers and constructors, especially for industrial floor. That is why I think so important to study the structures’ hindered deformation. Cracks commonly are a result of multiple factors including thermal contraction, creep and shrinkage. The internal constraints can generate extra stresses even from the start of concrete bonding and hardening. If the internal stresses exceed the actual tensile strength of concrete at any moment, cracks can appear on the surface. So the only way to prevent the formation of cracks, if we are able to describe the occurring nonlinear processes in the structure (e.g.: forming of shrinkage, hardening and developing of elastic modulus) and choose the appropriate material model. Plenty of material models are available to describe the drying shrinkage like EC, ACI 209, Bazant B3, or CEB MC90. These models taking into account several geometrical, concrete technological, and environmental factors. The forming shrinkage deformation along the cross-section are hindered by the generated friction between the bedding course and the floor, so the stresses are rearranged too. The value of friction coefficient are depended primarily by the bedding roughness and the type of foils. During my research I carried out experiments in this regard.

The "Beautiful Village" projects of China – Reconstruction of the old village in China PENG Jun*1 and GAO Ying* *
Environment and Architectural Art Faculty of Tianjin Academy of Fine Arts, China
Index Terms: Beautiful Village, Subject, Rural tourism, Resources Protection
Recently, the word “beauty village” has extensively enters our field of view in China. To face the great construction and development potential, it inspires the design community’s great attention. This article goes though the inspiration on Construction with Living Environment of “Beauty Village”, the current status on village construction, the exploration on “beauty village” design services, the principle use on developing tourism, the protection on village resources and etc. to expatiates. The purpose is to speak freely and to discuss the root issues with our fellow on “beauty village”, with the best hope and forces to make it realistic and charming. What is beauty? Let’s see the word in Chinese: ""the big sheep is beautiful, so the beauty is sheep and big"" (from the Chinese Ancient ""kangxi dictionary”). As you can see ""beauty"" is a associative compound. Among all animals, sheep provide the main meat to human, its meat is sweet and refreshing, is wonderful food. So the word ""beauty"" is a ""sheep"" above and the following is a ""big"". ""The nature of li, also to travel. The deer, see the food it will travel, from deer rhythm"" (from ""the kangxi dictionary).Visible, ""li"" is a knowing word meaning refers to travel. Is the characteristic of a deer, eager to find food, will travel and migration, so the font used ""deer"" edge, ""li"" phonetic element . There is fresh food during the journey, for urban people who naturally will have to think of the village, The ancients of China also through the composition of Chinese characters seems to tell us, ""Beautiful"" and village exist inextricably linked. In the current era of industrial revolution 4.0, Chinese people think about “the unity of heaven and humanity” once again, In the rapid development of urbanization process, construction of ""Beautiful Village"" should not be confined to become urban people who want to visit the “Garden in the Backyard”. It is related to the rural economy and people's livelihood, the rural traditional culture of discarded, improve the quality of living environment, the develop-discard of traditional culture in the countryside, improve the quality of living environment, the return of the sense of belonging of the peasant. Consideration of above factors, it is possible to achieve “with mountains in sight and waters in view, people will remember hometowns”, to achieve the sustainable development of rural economy. Finally, Make the “Beautiful Village” as an important component of China's rural areas, not only beautiful, but also rich and civilized.

Index Terms: telemedicine hub, internet of things, fast data, big data, IoT time series, sensor data
Today, the most people have smart phone, smart fitness equipment or any other tool to track the fitness activity and collect measurement data during a sport activity or just when the user walking on the street. The recorded data could be very useful if the data owner gets sick or has a medical examination. In these cases, the physician must access the earlier created medical records from the medical- or hospital information system and should access the recorded health related data from a global health information system to make correct decision. To integrate these types of health-related information into the current hospital- and medical system could be very expensive and takes a long time. In this paper, we will discuss a system what will made the integration easier and cheaper through open and standardized application programming interface. We present a unified service architecture with the corresponding common interface recommendation for integrating classical medical systems from the following areas: hospital information systems, interconnection of telemedicine systems, legacy health care systems, smart health devices and health-related smartphone applications. Emerging internet of things open new horizons for the medical care solutions. Through our telemedicine hub the physician can monitor the collected data real time if it is necessary while the patient is personally offline during the medical examination. Real time processing of the internet of things time series is new disciplines and there are more open questions. We will discuss the usage of fast data term in our system to analysing the incoming stream almost real time. The discussed system works with huge number of active devices and able to store and process the produced mass of unstructured data by the sensors. The recorded measurement data is available through an open and standardized application programming interface.

Diagnosis of complex process systems based on coloured Petri nets PÓZNA Anna Ibolya*1 *
Department of Electrical Engineering and Information Systems, University of Pannonia, Veszprém, Hungary
Index Terms: fault diagnosis, qualitative model, coloured Petri net, structural decomposition
A novel fault diagnosis method of process systems is proposed here where the systems are modelled by coloured Petri nets. The operation of the process system is represented as a sequence of consecutive events where the variables can take up qualitative values. The proposed diagnosis method is based on the deviations between the traces of the normal and the faulty operational modes and the occurrence graph of the coloured Petri net model. Modelling and diagnosing multiple faults and faults occurring during the process are also possible with this method. In case of complex systems the occurrence graph of the model can be extremely large which causes the growth of computational effort of the proposed algorithm. To solve this drawback the diagnosis method is improved with structural decomposition. The system is decomposed into separate components and after that the diagnosis method can be applied on them one by one. This causes smaller occurrence graphs and less computational effort. The method is illustrated on simple case studies.

Synthetic parameters to promote energy sharing system in urban areas: Biomass Energy Ratio for organic fraction evaluation in relation to urban district typology PRACUCCI, Alessandro*1 and ZAFFAGNINI, Theo* *
Department of Architecture, University of Ferrara, Ferrara, Italy
Index Terms: Biomass, Urban pattern, Energy Efficiency, Biomass Energy Ratio, district, energy sharing
The challenge to reduce Greenhouse Gas emissions (GHG) and support alternative solutions to traditional fossil fuels have a central role in energy efficiency practices and the development of Renewable Energy Sources (RESs) is part of this framework. Despite the European and national targets issued by Community, have allowed the achievement of good results, for the post-2020 policies is fundamental an in-depth analysis to maintain and, possibly, increments the current positive renewable energy trend. In this context a crucial and open direction is the upgrading of RESs in optimized model to be applied in the greatest energy consumers: Cities. In fact, Cities host the most part of world population, billions of people who need energy for their homes and for the related services. The need to work on Cities has to address innovative changes in RESs’ application methodology, able to exploit in-house sources – energetic, technical, social, etc. – in order to propose feasible solutions in a circular economy way involving all local stakeholders. In this scenario, the considerations related to district level can represent a relevant opportunity. Indeed, thanks to its contained dimension – halfway between city and building –, district allows the development of possible strategies for RESs application, able to generate an affordable economy of scale and contemporary stimulate a new awareness in citizenships through local sources’ potential exploitation. In RESs options, cities’ biomass represents an absolutely interesting chance. Bio-waste, green waste and sewage are daily produced by districts, and offer a huge energy potential today mainly uselessly dispersed. Understanding the quantity of biomass potential is a first phase towards its promotion. Each district, in relation to its urban morphology and population density, can affect the quantity of biomass produced and, consequently, address its use. For this cause, it is fundamental to identify evaluation tools able to associate energy opportunity of biomass utilization. These tools could be parameter for cities stakeholders – citizens, neighbourhood community, local Small Medium Enterprises (SMEs), Institutions – to evaluate such RES feasibility. The present work, through the relation between urban morphology and building typology identifies a synthetic energy parameter to calculate the biomass convenience. Though the reading of spatial specific district parameters, measurable in each possible case study, the Biomass Energy Ratio aims at being an instrument useful to understand the biomass energy potential for existing, or for designing, urban areas.

Reusing former industrial buildings – a project in Germany RÁCZ Tamás*1 and ZOLTÁN Erzsébet Szeréna† *
Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary † Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: reuse, refurbishment, sustainability, workspace, industrial
Refurbishment is an inevitable tool of sustainability which also provides the continuity of the existing building stock. To become more widespread than demolishing - which often proves to be the less elaborate action - the advantages and benefits of refurbishing must be emphasized. This paper is a brief summary about three former industrial buildings that are reused as contemporary office space in Ludwigsburg, Germany. The concept of design was to keep the industrial look of the buildings, even emphasizing it by using contrasting colours on structural elements, keeping the workplaces as neutral as possible. The placement of meeting rooms, focus-rooms and lounges provide the configuration of teams working together what is required for a correct and well-running workflow. These functions are a combination of spaces both for collaboration and concentration, and are easily accessible for the users. Green islands show up in the layout with multiple purposes: separating the different functional areas and improving the air quality by removing pollutants. Turning industrial halls in to offices is more than challenging, as the key to success beyond design is to solve the acoustic problems which occur in open space layouts anyway, but in rooms with for this function quite extraordinary parameters even exponentially.

Visual evoked potentials in response to various spatial patterns embedded in dynamic random dot correlograms and stereograms RADÓ János*1 and BUZÁS Péter† *
Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary † Medical School, University of Pécs, Pécs, Hungary
Index Terms: DRDC, DRDS, patterns, dynamic random dot correlograms, dynamic random dot stereograms, VEP,
Dynamic Random Dot Correlograms (DRDC) and Stereograms (DRDS) are widely used to investigate the stereo vision system. The rationale is that subjects can detect spatial patterns defined by areas of different binocular correlation or disparity only if their stereo vision system is functional. We record electroencephalographic responses, so-called visual evoked potentials (VEPs) of healthy human subjects from 64 electrode positions on the head in response to DRDCs and DRDSs in order to localize brain centres supporting stereo vision. Here we were interested in the type of spatial pattern that evoke the most reliable VEPs. The spatial patterns tested were as follows: full-field, a central square (10×10 degrees visual angle), horizontal or vertical stripes and checkerboards (4 deg/pattern cycle). Subjects (n=4) viewed image sequences where one of these patterns appeared from a pattern-free background at a constant frequency of 1.875 Hz. The binocular disparity of DRDSs was 0.5 deg, which is close to the highest sensitivity of the average subject as determined by reaction times to similar stimuli. We analysed the modulation of the steady-state response recorded from the occipital electrodes at the fundamental frequency and its 2nd harmonic. Statistical significance of the response modulation was tested using the T2o test. We found that the reliability of the responses depended on the spatial pattern used. For DRDCs, full-field modulation evoked most significant responses. For DRDSs, vertical stripes and the central square were the most effective patterns. We will thus use these patterns in our on-going investigations on disparity- and correlation sensitivity of VEPs.

Investigating the urban heat island phenomenon using mobile transverse method: A case study of Colon street in Cebu City, Philippines ROWELL RAY Lim Shih*1 *
Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: Urban heat island, Colon Street, Urban temperatures, Mobile traverse, Urbanization
Rapid urbanization has resulted in temperature differences between the urban area and its surrounding areas. Academics have called this as the urban heat island phenomenon. Among the places that have seen rapid urbanization is the City of Cebu. The Philippine’s oldest street, Colon, was chosen as the study area due to the near absence of vegetation and closely spaced buildings. Buildings that are spaced more closely as well as multiple absorptions and reflections produce higher and more viable street temperatures. This study tries to systematically understand the urban heat island effect between Colon and Lawaan, the rural area defined in this study. In order to quantify the urban heat island between two given locations, the mobile traverse method during the summer time, for a 10 day period in May 2016. A digital thermometer measuring platform was mounted on top of a vehicle to measure the different temperatures of Colon Street. Urban temperatures were also gathered in the Lawaan area using the same device. Preliminary results showed the presence of the urban heat island phenomenon between the two areas (∆T =1.17°C). The provision of green spaces, water features and proper urban planning are essential in mitigating future urban heat stress due to anthropogenic changes of existing cities.

Measuring ballast water in sewer systems RUSNÁK, Dušan*1, STANKO, Štefan * and GALBOVÁ, Kristína* *
Department of Sanitary and Environmental Engineering, Faculty of Civil Engineering, Slovak University of Technology, Bratislava, Slovak Republic
Index Terms: sewage, ballast water, measurement
Ballast waters are a common problem of many sewer systems. As such, ballast waters are an indication of sewer pipeline faults like construction or design errors, material fatigue or outside influence. There can be consequences to the environment and danger to public health resulting from these faults and increased costs for the operator of the sewer network, in terms of reconstruction of damaged parts of the network and also the added cost of greater flowrate in the sewer and waste water treatment plant overload. To start the reconstruction, or even to mitigate the impact of the ballast water, we need to identify the locations and quantity of faults in the sewer and, of course, the quantity of ballast water. During our research, we measured ballast waters in three different towns in Slovakia, on various parts of their sewer networks. This article encapsulates our experience with the identification and measurement of ballast waters and addresses methods for field measurement of ballast water flow rates.

Understanding the role and importance of facade design through case studies SANTOS-BLASTIC, David *1 and STOCKER György* * Department
of Construction Materials and Technologies, Budapest University of Technology and Economics, Budapest, Hungary
Index Terms: building facade, design practice, performance, case study,
Since the building envelope is a significant component of today’s energy-conscious construction, façade design has an emphasis not only on aesthetics and shaping the built environment. Therefore, façades are results of a complex, cross disciplinary and multi objective process, especially in the early design stage. In order to achieve the optimal solution, the evaluation of different façade performance indicators is needed, which are generally fall into three major categories: functional, financial and environmental sustainability. Environmental awareness plays a big role in our everyday life, due to this reason a number of researches and studies are based on facades energy-oriented developments or analysis. Accordingly, one would expect that energy efficiency related performance indices affect the design approach more than any other attribute. This, however, is not necessarily obvious in the design practice. In our presentation we are investigating the development of the façade design process through case studies of different public buildings: by analysing the design phases, highlighting the building-constructional, financial and energy-consumption-wise possibilities and barriers of the project, thus summarizing the most significant milestones which considerably determines the outcome.

Index Terms: generative design, parametric design
The main objective of this presentation is to introduce the practical application of parametric design in architecture, and demonstrate how it can be transform the architectural routine. It is no question that it is not expectable to use parametric design in every field of architectural practice, but it is way more expansively applicable than most people think. This project was made to a design competition, to represent the cooperative work-flow between the architectural and the parametric design software. Because of this it is also great example project to represent the advantages of parametric design in architectural planning. The project contains a special curtain wall what is one of the most spectacular application of parametric design, but there are many other solutions which follows the architectural thinking in the parametric design program, and makes the design of the building capable to follow the changes in the plan without the designers extra work. It is a common question if it is worth the extra time to make a parametric program for a building. There is not a general answer to this question, but this project gives a closer look and a different perspective to this question and it also offers some general solutions which can be useful by many buildings.

Index Terms: origami, architecture, kinetic structures, parametric architecture
Nowadays everybody is familiar with the origami techniques. There is no real proof of its origin, but it is generally accepted that this ancient technique of folding paper comes from Japan. Up to the 18th century it was spread all over Europe too. From its beginnings, origami was used in science, in kindergartens for developing the children skills for math and geometry. Today even professionals use origami in their work. The technique has been developed in many different ways which can be used in various scientific fields, for example in biology, math, medicine, geometry, engineering and architecture. Our research is based on the architecture field. Considering that the topic is interdisciplinary, and not only thinking of different fields of use, but if just analysing the architecture side of origami, we divided it to two groups. First group are the fix origami structures mostly built in the beginning of 20th century. These structures give us new possibilities of arranging the space. We can surface bigger space without any supporting elements. It is possible because of the folds of structure and the effect of forces in it. Today, kinetic architecture is present more and more. Since origami structures have a special transformability potentials, our second group are the kinetic structures. The goal is the cooperation between the environment and the building and we are trying to reach it by flexible structures. Also, we presented several existing examples for types of kinetic screening structures that, for example, respond to the movement of the sun. With these and similar theses we are trying to bring the origami technique closer to architecture and its consumers, and we hope we shell succeed.

Index Terms: groundwater drawdown, piezometric head, pumping well system, transient simulation, TRIWACO
The overall purpose of this research is to model flow extraction from several groundwater network wells to control the excessive groundwater level. The study is conducted in Nitra industrial park which is located at the northern part of the Nitra Town, where confined groundwater table is situated very close to the terrain. The area of interest is a plane with mean elevation of 142m a.s.l. The elevation of groundwater can rise up to 141.0 and 143.0m a.s.l. during dry season and extreme climate conditions or during flood wave in Nitra River, respectively. In order to keep the level of piezometric head below 140.0m a.s.l. (as requested by the investor) there are already 38 wells realized around the area of interest with pumping rates. The numerical groundwater modelling is applied using the TRIWACO modelling system for a given hydrological, geological and hydro-geological conditions. The transient simulation takes into account the process of groundwater level drawdown during the possible flood wave in the Nitra River for historical discharge of Q1000. The paper will present numerical modelling results on design of drawdown system to decrease the groundwater level to acceptable elevation, and as well as parameters and uncertainties for design purpose.

Index Terms: temperature correction, IT-CY, asphalt stiffness, back-calculation
The paper addresses the determination of a stiffness-temperature correction model for the use in a mechanistic overlay design method, under development by the author and colleagues. Eleven models are selected and evaluated based on 215 laboratory stiffness test results at various temperatures of 47 different AC22 binder course type mixes. As results showed, for the rough temperature correction of Hungarian binder course mixes for the use in the proposed design method, the model used by the AASHTO 1993 pavement design method is most accurate based on the standard error of the estimate of the selected models.

Index Terms: image, leaf, segmentation, global
As part of an optical recognition of ragweed (Ambrosia Artemisiifolia L.) project, morphological identification based on the shape of leafs is performed. To increase and in the meantime challenge the achieved 71% accuracy of the initial setup, the sample space was extended with real field samples generated by botanists. These real field samples however contain various environmental noise, even though the best effort of the botanists, therefore the initial pre-processing and pre-segmentation methods generated incorrect results and thus the final classification was also breached. The environmental noises considered in the current work are as follows: miniature point like intensity difference; the intensity of the background and of the image are locally homogeneous, but globally inhomogeneous; there are shadows resulting from the leaflet parts erupting from the background plain; and over illumination of same parts of the image. Shadows are usually examined based on the properties of textures / colours on both sides of the gradient, in other words it is decided for each gradient whether it is a result of lighting differences or of the change of the visual structure of the object. This method can be well used for fine tuning the information content of an edge, nevertheless it requires high computation effort and moreover it does not guarantee to border completely neither the object nor the shadowed in area. In other words, this method is not suitable for the current morphological examinations of the leaves. A new global segmentation method is presented in the current work, specifically developed for the real filed images taken by botanists which generates appropriate binary images of the leaf shapes for further processing. As part of the solution, new thresholding processes are introduced based on the relationship of border and image histograms and a source converter is also introduced which can increase the efficacy of the special cases of the various thresholding processes used. Finally, it is shown how the sources and processes should be selected depending on the input.

Index Terms: Collective housing, living spaces, trends, Prishtina
The collective housing buildings in Kosovo have started to be constructed since 1947. Such buildings were constructed in urban areas such as Prishtina to later continue in other cities of Kosovo, whereby one notices a combination with regard to the organization schemes put in use. The purpose of the research was to investigate the models of collective housing buildings and their respective characteristics. As a case study one took the collective housing buildings which were constructed in various time periods divided into two groups: those built between 1947-1999 and 1999-current. The utilized methods for the purpose of this research were: 1. Analytical method and 2. Comparative method. The results revealed that the size of the living surface in collective housing buildings built after 1999 has been reduced compared to the buildings constructed earlier, which implies that the trends in our country went into the direction of reducing the living surface. In addition to reduction in size of living space, another element which is visible is the change in the functional aspect. However, what is the opinion of the citizens regarding the mentioned buildings? The quantitative method which is utilized during this research was performed through processing of eight hundred questionnaires with random citizens, the latter were over 18 years old in various cities in Kosovo. The aim was to understand the opinion of the citizens regarding such buildings. The questionnaire consisted of eleven different questions. The results led us to understand that the citizens express dissatisfaction with the lack of storage areas, elevators, green areas, playgrounds for children and lack of parking space.

Index Terms: Unsere jüdische Baudenkmäler aus dem 18. Jahrhundert, durch der Vorstellung der Renovierung von der Synagoge Óbuda
Die wichtigste Vorkomnisse der Geschichte von dem neuzeitlichen Judentum waren die religiöse Reformation in dem Jahrhundert 18 bis 19. Dieser und der nächste Zeitraum wurden von der Philosophie des Bescheid beherrscht. Die geistige Leiter haben wacker und ausgezeichnet von sich gehaltet, ihre Aufgabe waren, dass sie die Welt von dem Mittelalter ausleiten können. Die neue Idee wurde sich in vielen Staaten politische Wirkungen ausgewirkt. Im 1750 waren viele Versuche das System und die Gesetze der Monarchie zu rationalisieren. In dieser Zeit wurde sich die chassidischen Bewegung in Ost- Europa, größtenteils in Galicien, deren Gründer war der Rabbiner Elizer Yisrael Baal Weder Tor. Während dieser Zeit haben sich die aus Buda verbotene chassidische Familien in dem Eigentum des Familie Zichy in Óbuda. Die meisten Juden von Óbuda haben nach Inventur aus Mähren gestammt. Die erste Synagoge wurde im Jahr 1727 aufgebaut, die die Zerstörung bald verursacht wurde. Der Aufbau der zweite Synagoge wurde im 1765 datiert, aber über das Gebäude hat wenige Dokumente. Im 1765 hat die Witve von Miklós Zichy (geboren Erzsébet Berényi) eine Vereinbarung mit der israelite Bevölkerung von Óbuda festgelegt, deswegen wurde auf dieser Grundlage die dritte Synagoge statt der fällige Zweite aufgestellt. Das Gebäude mit Barock-Stil, aber wegen finanziellen Grund ganz sittsam hat mit Gottendienst im 29. September 1769 geöffnet. Das Bauwerk wurde in einen kritischen Zustand kurz nach der Übertragung angekommen. Máté Nepauer versuchte im Jahr 1788 das versenkte Fundament zu verstärken, aber an dem Gebiet mit Grundwasser war es nicht erfolgreich. Im 1817 hat der architektonische Vorstand Óbuda eine Delegation mit der Leitung von József Thalherr augeschickt, den Zustand der Synagoge zu analysieren. Nach dem Gutachten der Komission wurde das Gebäude abgerissen, und wurde sich die Aufbau der vierten Synagoge vorgesetzt. Die neuen Baupläne wurde von zwei Architekten vorgelegt: Mihály Pollack und András Landherr. Die Gemeinde hat im 3. April 1820 den Vorschlag von András Landherr wegen billiger Pläne und der stärke Gebäude ausgewählt, und am 23. April wurde den Vertrag mit ihm untergeschrieben. Der Bau der Synagoge ist im 12. Juli 1821 abgeschlossen. Das Bauwerk wurde in klassischem Stil aufgebaut, mit der empirischen Einrichtung. In meiner Präsentation wurde historische Entwicklung, die Recherche dieses Gebäude und die Gebäudesanierung auf Basis von Ergebnissen vorgestellt.

The main objective of this presentation is to introduce the practical application of parametric design in architecture, and demonstrate how it can be transform the architectural routine. It is no question that it is not expectable to use parametric design in every field of architectural practice, but it is way more expansively applicable than most people think. This project was made to a design competition, to represent the cooperative work-flow between the architectural and the parametric design software. Because of this it is also great example project to represent the advantages of parametric design in architectural planning. The project contains a special curtain wall what is one of the most spectacular application of parametric design, but there are many other solutions which follows the architectural thinking in the parametric design program, and makes the design of the building capable to follow the changes in the plan without the designers extra work. It is a common question if it is worth the extra time to make a parametric program for a building. There is not a general answer to this question, but this project gives a closer look and a different perspective to this question and it also offers some general solutions which can be useful by many buildings.

Analyse construction norms based on BIM supported manufacture SZIGETI Renáta*1 *
Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: construction, budget, norm, BIM
With the fast development of technology there are more and more softwares and programs available that supports the construction process. It is a fact confirmed by Building Information Modelling (BIM) and budget creator programs. The task – beside making the construction process economical and analysing the construction norms - is to optimize the theoretical and operational difference between these programs and the BIM. The improvement of building manufacture is supported with BIM. With the help of a detailed and updated model the material amount calculation, budget and schedule creation are more effective. Based on the collision test the construction impacts can be avoided, and also the waste management can be improved. The examination and reconsideration of the norm system will be made through an own project. After the selection and regulation of the manipulable workflows the goal is to create new norm times from the new results. The conceptual difference between BIM and the other budgeting programs is that the other programs have a norm system and workflow foundation, while BIM is a method, supported with an element based model. The expected result is to create such BIM norms that can help to produce more efficient and precise budget.

Analysis of historical masonry mortars with scanning electron microscope and other special methods TÖRÖK Brigitta*1 *
Breuer Marcell Doctoral School, Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: mortar, diagnostic, SEM
Restoration of cultural heritage masonry buildings requires detailed analysis with the help of effective diagnostic methods. Justification of the adopted repair or strengthening measure is a very important and complex task that requires a multidisciplinary work. Besides visual survey, several types of diagnostic methods are used, such as georadar, video endoscopy, infrared thermography or drilled sampling. The most preferred ones are some of the non-destructive test methods. However in many cases sampling cannot be avoided so as to obtain consistent information about the components of the used materials, the physical and chemical deterioration processes that took place during the centuries, and the actual condition of masonry. In the present study well-known and innovative solutions of investigation are presented, highlighting that the most effective methods are those that provide valuable information for the structural analysis and assessment while they cause only minimal damage to the studied building. Geophysical methods such as georadar, video endoscopy and infrared thermography are widely used methods, however their routine application in restoration projects require further research. Scanning electron microscopy, neutron and X-ray elemental analysis and other methods can be considered alternative non-destructive methods, as the sample size needed for the tests is in the range of millimetres to centimetres. A feasibility study of using scanning electron microscope (SEM) is presented. In order to obtain a proper basis for comparison, several laboratory tests were carried out. Mortar samples with different composition and consistence were produced and SEM images on these samples were taken. Their microstructure was compared to those of historical samples. Compressive and flexural tests, after 28 days of hardening will be carried out as part of the research. The connection between the hardened properties and the images taken by SEM will also be examined. The complex use of the presented methods helps evaluate the condition of the structure, and gives the opportunity to investigate economically and authentically hidden structural characteristics. Although these characteristics may be important for the assessment and making proper restoration plans they often remain unseen by using conventional practices.

Problematic of the simulation and modelling in the aspect of lightning protection TÓTH Zoltán*1, KISS István* and PALOTAI Roland* * Budapest
University of Technology and Economics, Budapest, Hungary
Index Terms: lightning protection, simulation, modelling
One of the main topics of the lightning protection conferences is the protection of the renewable energy plants. Within that are the wind turbines. The increasingly powerful units have bigger size, therefore we have to rethink and refine the classical space calculation models. In our work, we use the method PMAS and its measurement setups of Prof. T. Horváth as a starting point. In case of some setups, PMAS and similar methods give different results from the expected values. 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. In our work, we present simulation and modelling problems for different setups to give a solution to this problem.

Index Terms: energy efficiency, building typologies, optimisation
Nearly 40% of total energy consumption is accounted for heating of households. Decreasing primarily this type of energy need could contribute significantly to reduction in energy demand. However, as any kind of intervention, it has a significant cost commitment, considering either the energy production side or postapplied thermal insulation. Various national and international studies of building typologies determined the requirements concerning the energy efficiency of residential buildings. Development options for some residential buildings are analysed in this paper presenting the best return rate and shortest return period. The main goal is to determine the optimum solutions for increasing energy efficiency.

Index Terms: school expansion, town development, sustainability, education, interior design, expansion, playful spaces, natural materials
Regarding the fact that almost 99% of the world’s build environment consist of existing building stock, it is crucial task for a fundamental sustainable development in building industries to have special focus on the energy efficient and environmental conscious renovation and recultivation of existing buildings. Significant part of these old buildings possess bad structural quality, low energy efficiency and comfort level with high CO2 emissions. Concerning this background, an implemented project enabled to demonstrate a residential building’s refurbishment in a special way: Instead of regular energy efficient refurbishment, specific goal of particular project was to “tune up” the old, existing building’s sustainability “as strong as possible”, meaning the efficiency should be as high as conceivable to create a first refurbished active house in Hungary that generates more energy, than it demands. The special building requires also unique design technology. Dynamic thermal simulations supported the whole planning process, from the sketch planning till the construction planning work packages. Different sketch plan variations were developed to be available for simulation analysis. The best compromise between energy, comfort, architecture and functionality was defined and could be identified for further elaboration and implementation of the building.

Index Terms: International Eucharist Congress, outside liturgical space, Jenő Lechner, Jenő Kismarty-Lechner
The 34th International Eucharist Congress held in 1938 was the biggest event of Hungarian Catholicism in the 20th century. The series of celebrations recalled the Millennium both in size and appearance, and its importance was raised by the fact that the Hungarian Catholic Church could organise it on the 900th anniversary of the remembrance on St. Stephen, founder of the state. The spiritual preparation of the Congress was served by the so-called Dual Holy Year, but the effective practical implementation was also essential for a successful appearance. The series of programs mobilising huge crowds had not only architectural significance, but its effect in urbanism, interior architecture and church art was manifested as well. Several comprehensive works dealt with the religious-theological background and historical overview of the Congress, its significance in architecture and architectural art is still not described sufficiently. However, the re-evaluating the experiences of the event became topical, since Hungary will host the already 52nd occasion of the Congress. Our research intends to give evaluation of church buildings related to the event: on the one hand, the venues of the capital programs provided place directly for the events of the conference, however, several constructions were realised in connection with the conference year with the intent of renewing and expanding the exercise of worship of small local communities (partly in Budapest, partly in rural towns). The study analyses the concerned buildings, new architectural interventions and planning tasks alongside the venues of the program series in 1938. A special emphasis was put on the architectural tender of the ornate altar built at Heroes Square, on its evaluation in the aspect of architectural history and on the method of its realisation. Although significant professional commissions concentrated mainly in the capital, townscape-shaping developments, church buildings and renovations occurred in rural towns as well. The so-called ‘Gold Train’ in relation with the country visit of the Saint Right connected these venues - not only for the Catholic but for the whole Hungarian nation. Therefore, we concentrate on the architectural aspects alongside the Congress’s role played in the spiritual renewal processes. The study aims to give a still awaited evaluation of the architectural framework embedded to this social and cultural environment.

Faculty of Engineering and Information Technology, University of Pécs, Pécs, Hungary
Index Terms: vision, machine vision, colour
Digital imaging has a several decades long history. Devices, standards and methods were developed, however, colour representation has still it's problems. Colour matching and calibration of camera and display devices is more or less a common routine for digital image processing. This tasks are done during the pre- and post-processing part of the work. With the appearance of cheap, lightweight and high quality cameras, more and more applications are rising in the field of imaging. Some of them need real-time colour information, thus post processing is not always a solution. The use of image series or video frames under variable illumination conditions requires not only postprocessing, but more real-time processing of colour information. This could be achieved by modern, multicore, portable systems and use of different sensors and calibration data on the flight. The research ideas are based on these and on different autonomous platforms which could make advantage of the concept, like drones and all kind of robots.

Index Terms: strengthening, jacketing, circular column, triaxial stress, compatibility
In this paper the application of a deformation based analytical approach is presented to calculate the strength-increase of axially loaded circular columns, strengthened with FRP and RC jackets. A short introduction of calculation methodology and adopted basic assumptions are explained. Through a trial-and-error type iterative procedure the magnitude of confining stresses and confined strength of core material are determined, based on the compatibility of lateral deformations of core column and jacket-wall. The accuracy of proposed model is evaluated by comparison with 149 test results. Test results also include three experiments of RC jackets. The absolute average error of analytical results is found as 8.9%. It is highlighted, that with the extension of the proposed model it can be a general tool to calculate the confining effect of jackets of square columns as well.

One of the most important elements of architectural designing of our days is the façade. Primarily the façade defines the external appearance, the image of the building, this is the first thing everybody sees, when glances on a construction. Today as regards designing buildings an increasing demand seems to exist for transparency, that is, for full transparency, as regards light, air and also the nature, but it raises buildings energetic questions too. The curtain walls and the glasses stimulate the manufactures to develop in the areas of support structures, aesthetics and building physics as well. Do these curtain walls to reach the desired effect in terms of energetics?

Index Terms: constructive geometry, central projection, practical perspective, special cases, Ceva's theorem
A projection plane and a cube in general position is given. The trace points of the significant lines and the trace lines of the planes of the cube compose an acute-angled triangle with special points. In central projection, the vanishing points and lines of the above elements create a configuration similar to the former one. The central projections of these configurations are similar to the former ones. We may apply this shadow as a construction tool and we can gain the perspective picture of the grid of space-filling mosaics of cubes without taking vanishing points. This can be the constructive and logical frame of graphic art works. By adaptation of the delineated tool, projections of parallelepipeds and 3-dimensional models of moredimensional cubes can be constructed as well. It can be deduced from our way of construction that Ceva’s theorem is valid for images of parallelepipeds’ vertices and relevant trace triangles as well.

Index Terms: Mongolian, architecture, yurt, decoration
From an architectural point of view, different cultures breed different architectural forms and architectural styles during a variety of nations’ historical development. Nomads of Central Asia and the Mongolia plateau have created their unique architectural form - yurt. It is not the original creation of a master architect, but the crystallization of the living cultural development of many nomads, and has been in use ever since. For thousands of years, yurt is not only the traditional residence of Mongolian herdsmen, but also the symbol of Mongolian traditional way of life. The yurt is the most economical in saving building materials, and environmentally friendly architecture form that dropped the consumption of natural resources to the lowest point, it doesn’t require adobe and brick, also no metal, requires only a small amount of wood, felts and leather can be made, construction without digging, demolition will not leave ruins. The main external decoration of the yurt, concentrated in the door, felt, side cover, top cover where have a lot of delicate decoration, at the entrance, often set up a Su Lide spear and other national decorations that are full of national characteristics. The yurt’s decoration is also rich in interior which is mainly embodied in the structural components of the yurt itself and the furnishings, by using the painting, sculpture, copper decoration and felt painting, etc. to express the profound national connotation. The outer colour of yurt is mainly white, blue, red, and exquisite yurt is embellished with other colours, white is the mainly colour, and also the background; indoor is red and white colour-based, interspersed with a variety of colour patterns, leather paintings and other decorations. Mongolian folk rich pattern art is an important express form of national decoration, such as geometric, animal, plants, which with peculiar conception, diverse patterns, strong national characteristics, reflecting the beautiful Mongolian folk customs.

Facility Management at University of Pécs was a challenging objective. More than two hundred buildings with several thousand premises and around half million square meters area belong to the central management. This large number includes small-sized outhouses, educational facilities, office buildings, dormitories and several hospitals as well. Their age and geographic location varies in a wide range. Although the original scope included only the area management, a special database was required to be able to use BIM for storing and recalling the surveyed data. The presentation will demonstrate the developed processes and solutions including the potential of the low detailed mass-models in BIM based CAFM systems.
