Project Supported By
About the Project Sensorisation of Injection Mould Tools created by Additive Manufacturing (AM) This I-Form Spoke project is undertaken by the I-Form team in collaboration with our industry partner, AbbVie. A number of their medical device components are manufactured using injection moulding as a core process. I-Form & AbbVie are funding research into Additively Manufactured (AM) injection mould tools that facilitate conformal cooling and offer greater design flexibility for mould sensorisation. Five key areas of research are being addressed by the team: •
•
•
•
•
Research into conformal cooling channels (CCCs), specifically the effects of surface roughness and channel features on improving heat transfer efficiency to the coolant. Research into embedded sensors that provide accurate measurement of in-process data, monitoring the effect of the conformal cooling channels, achieving enhanced process optimisation and closed-loop control of the process. Research into embedded sensors that provide rich data to demonstrate the ability of AM-produced mould tools to withstand the mechanical and thermal stresses within the injection moulding process, tool condition monitoring. Fully embedding wireless sensors into the cavity to minimise the number of wired connections on the machine and to achieve sensor locations that are not conventionally possible. These sensors are encased in the steel during the printing process. Cavity lightweighting, to take advantage of the design freedom offered by AM tests are being conducted on cavities that reduce the overall material used to produce the cavities by 40%.
This work will offer opportunities for further process optimisation and sustainability within the medical device manufacturing industry.

Smart Control of the Climate Resilience of European Coastal Cities
FOLLOW US ON SOCIAL MEDIA! SCORE H2020 Project score_h2020 @SCORE_EUproject SCORE – Smart Control of the Climate Resilience in European Coastal Cities
Project Description SCORE is a four-year EU-funded project aiming to increase climate resilience in European coastal cities. The project will tackle specific challenges related to sea levels, coastal erosion and extreme weather events using an integrated solution of smart technologies and nature-based solutions. One of the key activities under SCORE is to design, implement, and evaluate a novel framework of Coastal City Living Labs (CCLL) that will enable citizens and stakeholders to co-create and co-design the solutions with scientists, researchers and engineers to make sure these are sustainable and acceptable by the society. Therefore, SCORE outlines a comprehensive strategy, developed via a network of 10 coastal city ‘living labs’, to rapidly, equitably, and sustainably enhance coastal city climate resilience through an Ecosystem-Based Approach (EBA) supported by sophisticated digital technologies. SCORE will reduce the impacts of sea-level rise and extreme events due to climate change on European coastal cities by co-design, and codevelopment with citizens and stakeholders, and by deploying, testing, and demonstrating innovative EBAs, smart technologies, and hybrid Nature Based Solutions.

Material and Failure Analysis of Domestic Wind Turbine Blade Lauren Banks
Dr Molua Donohoe
S00185157@atu.ie
S00185157
Wind energy is widely regarded as one of the most promising renewable energy sources, with the design of wind turbine blades playing a crucial role in the amount of energy that can be harvested. These blades are particularly vulnerable to destruction due to their exposure to unstable winds that can change speed or direction, resulting in cyclic and fluctuating loads. Therefore, the aim of this investigation was to analyse the material failure of a domestic horizontal-axis wind turbine blade using a combination of computer-aided design (CAD) simulations, manual calculations, and physical testing. The outcome of this investigation detailed the blade's resistance to impact, material performance, and cycles to failure. Three-Point Bend Testing Results The wind turbine blade was able to sustain a maximum load of 2638.75 N before failure and failed when the flexural load reached 184.59 N. The stress at failure was 5.40 MPa, lower than the maximum stress experienced during the test, indicating potential material defects or stress concentrations. The maximum strain was 4.62 and the maximum deflection prior to fracture was 40.35 mm. Similar results were obtained in the testing of specimen 2, with a maximum load sustained of 2538.40 N and maximum stress experienced 73.5 MPa. Negligible deviations were observed in test 3 where the maximum load sustained by the blade during testing was 2732.37 N. The load that caused the blade to fail in the outlier test was 138.22 N. These values inform the strength, durability, and maximum wind speed at which the blade can safely operate.
Blade Material Specifications PAG glass-reinforced material is a type of nylon material known for its high mechanical strength, excellent shock absorption and sound attenuation properties, good electrical insulation properties, resistance to heat, low friction coefficient, abrasion, weak acid, alkali, and general solvents. It has a temperature range of -40 ℃ to +110 ℃. According to the material design specifications, it’s a highly versatile material that possesses a variety of excellent mechanical and physical properties, including a tensile strength of 165MPa and a yield strength of 103.6MPa, an elastic modulus of 2620MPa, an elongation rate of 25%, and a density of 1120kg/m³.PAG glass-reinforced polyamide blades are lighter and thinner, reducing the overall weight of the structure and resulting in savings in raw materials and energy consumption. The material can easily be moulded into various blade designs that closely match the theoretical design.
Fatigue Testing Results The results from practical testing allowed for a half-log S-N curve to be constructed. The results shown below, detail the following results: • The specimen will fail at 104 cycles when subject to a stress amplitude greater or equal to 1.22MPa. • The specimen will fail at 106 cycles when subject to a stress amplitude less than or equal to 1.10MPa. • Test specimen 5 was not subject to failure thus, the cycles to failure remain inconclusive. The fatigue cyclic loading tests on PAG glass-reinforced polyamide specimens showed that decreasing the total load increased the number of revolutions. Specimen 1 failed after 3999 revolutions due to an initial load higher than the allowable load. Specimen 2 reached failure at 6543 revolutions, while Specimen 3 failed after 7142 revolutions. In contrast, Specimen 4 showed the most accurate results as the fibres ran perpendicular to fracture, allowing for more stress resistance. Specimen 5 operated continuously for over 300,000 revolutions without failing. Test 4 results were consistent with material specifications, which showed that fatigue specimens failed after 241,425 cycles when the fibres were oriented parallel to the load and 525,900 cycles when fibres were oriented perpendicular to the load.
Charpy Impact Testing Results Charpy impact testing was conducted and found to be in agreement with the values reported in online sources. The average result obtained was 0.811J, which is within the acceptable range. This results in an impact energy of 8110J/m2 which indicates the amount of work required to fracture the specimen under impact loading. This suggests that the material has low impact resistance, rendering it unsuitable for applications that require resistance to sudden impacts, such as turbine blade construction. Project Conclusions The objective of this evaluation was to assess the blade's ability to withstand failure, which has been successfully achieved. The material exhibits several desirable properties such as a high flexural modulus, microstructural orientation perpendicular to force, high cycle fatigue performance below 1MPa, and the ability to withstand significant displacement, stress, and strain. However, it was observed that the material did not fully meet the expected material specifications. The material demonstrated brittle fractures at room temperature, indicating unsuitability for colder climates where sudden impact due to foreign flying objects or high winds is a significant concern. Therefore, a more ductile material may be better suited to such environmental conditions.
Solidworks Three-Point Bending Simulation Through Solidworks analysis, it was discovered that the blade could endure a maximum load of 260N, resulting in a maximum stress of 1.684x107 N/m2. The analysis also showed a maximum displacement of 37.76mm and a maximum strain of 9.612x10-3.
The microstructure observations from Charpy test specimens seen above, reveal a visible glass fibre structure. The impact on the material is perpendicular to the fibre structure, resulting in more even distribution of stress across grain boundaries and better resistance to impact. The figures above show the fracture surface and area of the crack propagation.
Similarly, the microstructure is observed where the complete blade underwent three-point bending, which highlights the significance of dispersed fibres for enhancing mechanical properties, such as strength and toughness, in PAG glassreinforced polyamide. Therefore, it can be inferred that the blade’s fibres exhibit a vertical orientation.
Based on observations through SEM, it can be inferred that fatigue samples 2 and 3 (left) fractured parallel to the grain direction of the reinforcing fibres, which is weaker compared to perpendicular fractures. However, specimen 4 (right) fractured perpendicular to the cyclic loading, which is similar to the actual blade structure. Therefore, the results obtained from test 4 correlate accurately with real-world loading on turbine blades. In composite materials, fibre orientation and loading direction affect material strength and characteristics.

The Effect of Flow Arrangement on Thermal Power Transmission in a Double Pipe Heat Exchanger (Micheál Burke S00198519) Objective: The objective of this thesis was to examine the effect of parallel and counter flow arrangements on thermal power transmission in a double pipe heat exchanger (DPHE). Mathematical analysis, CFD software, and experimentation were used as the modes of investigation. Parallel Flow vs Counter Flow: A double pipe heat exchanger is a device that transfers heat from one fluid to another. It consists of two concentric tubes made of a highly conductive material like copper. One fluid flows through the inner tube and the other fluid flows through the region between the tubes (annulus). Liquid water was the working fluid for this investigation. In parallel flow the fluid flow in the same direction. In counter flow the fluid streams move in opposite directions. (Figure by Omni Calculator) Parallel Flow Configuration (Experiment)

Truck Aerodynamics Martin Earley Contact Info
The Problem Looking at the transport industry in Europe, trucks produce 30% of the carbon emissions, despite making up just 4% of the vehicles on the road. With over 6 million HGVs on European roads producing 2.68kg of carbon for every litre of fuel used, this issue provides an opportunity for development in the area of improving the fuel efficiency of these heavy goods vehicles.
The Possible Solution Aerodynamics is one of the main components affecting fuel efficiency, especially at higher speeds, where the drag force, caused by the interaction between the vehicle and the air around it, becomes exponentially more prevalent than any other area of losses. The cab-over (flat nose) style lorry used in the EU in an aerodynamic disaster, and with electric truck technology still some time out, along with this technology introducing weight issues, aerodynamic development can immediately reduce carbon emissions and fossil fuel consumption.
Testing Using Computational Fluid Dynamics (CFD) and wind tunnel testing, a model of a standard European articulated lorry, which is seen everyday on our roads, was tested to find what features contribute to its aerodynamics, and what more can be done to improve the fuel efficiency of the vehicle.

Forces experienced by an endmill during Ayrton Gleeson machining Contact Info Introduction/ Aim This report will investigate the advantages of using either a large step-over or small step-down method using a standard endmill in a CNC machine versus using a small step-over and a large step-down method under the same conditions. Each method was scientifically tested under the same conditions within the general workshop to collect data and calculations will be carried out to use alongside the data produced by the experiment. The experiment will be carried out by machining a stepover of 3,5,7mm and a stepdown of 5mm. Then repeating the same step overs but increasing the step down to 10mm to compare results. One of the key features of this research was calculating the forces acting on the endmill and the amount of forces required to cut the material. The merchant circle was used to calculate the relevant forces in the x and y axis.
Merchant circle
Experiment and Data The experiment was carried out using a dynamometer. The dynamometer was used to detect the forces produced in the x,y and z axis. The dynamometer then produced a graph that could be studied and analysed
Analysis and conclusion The best method is the large step-down and small step-over. The reason for this is that having a large step down produces less force on the end mill than increasing the step over, it is evident that increasing the step over increases the forces in the y-axis and therefore puts a large amount of force on the endmill, the ratio of material removed to the force applied to the endmill is most efficient when the step down is increased compared to increasing the step over.

The Effect of Build Orientation on Mechanical Properties and Build Time for FDM 3D-Printed PLA Introduction & Background: Fused Deposition Modelling (FDM) is an additive manufacturing process in which extruded material is used to build a model layer by layer.
Progress:
CONNALL
Finite Element Analysis: • Using finite element analysis stress concentration was discovered in the model design from the small fillet radius.
The orientation in which FDM components can be built has no limitations due to the assistance of printing supports.
While orientation may not be limited; some orientations may be more desirable from the point of view of strength, minimising support, and reduced production time.
Objectives: • Investigate the effect of build orientation on mechanical properties and build time for FDM 3DPrinted PLA
• The fillet radius was increased and the stress concentration was eliminated
Methodology: Research 1. Additive manufacturing Technology • Fused Deposition Modelling (FDM) 2. Build materials • Polylactic Acid (PLA) 3. Additive manufacturing characteristics • Build orientation, overhang, stress concentration 4. Build parameters • Infill density, layer height, bed adhesion type, nozzle temperature, print pattern, print speed, overhang angle 5. Tensile test • Offers the fundamental design information necessary for understanding material capabilities Design • Design dog-bone FDM testing components suitable for tensile testing Analysis • Finite element analysis on the component model to look for any stress concentration within the component design • The small radius fillet was causing the components the fail at a lower force than expected, design modifications were made to eliminate the stress concentration Fabrication • 3D Print PLA FDM components in 5 standard build orientations Parameter Layer Height Nozzle Temperature Overhang Angle Print Speed Support Pattern Bed Adhesion Type Print Pattern Infill Density

Results: • The UTS for each orientation was manually calculated using the failure force and component cross-sectional area Build Orientation Flat 90° Flat 45° Flat 0° On Edge Vertical
Calculated UTS (MPa) 41.47 43.93 49.62 48.64 30.93
Build Orientation 15° 30° 45° 60° 75°
Calculated UTS (MPa) 39.64 37.81 41.29 29.89 22.36
Conclusions: • Mechanical properties and build time of the FDM 3D-printed PLA parts were significantly influenced by the build orientation • The interlayer fracture (between layers) strength is primarily determined by the interlayer bonding strength, while the intralayer fracture (within layers) strength is primarily determined by the extruded material strength • Tensile strength decreased when the build orientation of the components was aligned from flat to the upright direction and 0° to 90° printing angle • Horizontal (flat) build orientations yielded a maximum of 36.67% higher tensile strength than the vertical (upright) build orientation • Orientating the FDM part along the direction of loading tension will improve the ultimate tensile strength of the component

Test Framework for Automotive Lane Keeping Assist Software Luis Peluso
Supervisor: Dr. Muhammad Mahmood Ali
LFPELUSO@gmail.com
ID: S00194878
1. Introduction
3. Results
Performing earlier functional test of software is imperative for automotive companies to achieve acceptable time-to-market with expressive reduction of risks. It is known that presenting validation challenges sooner to software engineers can produce robust solutions that will pose less risk to further phases of the project and, consequently, more safety to the users. The principle of “Shift left” is the inspiration for this work (Figure 1). The necessity of testing earlier, with the same rigor and as close as possible to the validation phase is a growing demand for the automotive industry in general. Figure 1 – V-model: Verification and Validation Utilizing real-world units as the error output helps to “translate” the machine vision design environment into a more pragmatic reality, where solutions and scenarios can be mixed up and yield relatable results. This project explore a common test framework for heterogeneous lane detection algorithms.
2. Methodology This Framework is built in LabVIEW in order to facilitate the User Interface aspect of the lane detection task and facilitate visualization of data flow, which enable a targeted debugging environment for the Software Under Test (SUT) (Figure 2).
For all image-sets, individual frames were processed. Both the annotation and SUT processes run in parallel and the error is computed in run-time. Figure 4 brings the SUT process on top row and the annotation pipeline on the bottom – for the annotation, a machine vision algorithm based on Hough transform, needs an extra step for pre-processing the image.
Figure 4 – Test framework pipeline: top SUT and bottom semi-auto annotation.
The Bird’s Eye view is generated so the final image become uniform for measurement. The final error results are given in centimetres and relative to the centre of the road lane. Because image noise and the vehicle vibration, the ground-truth results still have some noise (Figure 5). The analysis of one of the test cases with the LaneNet SUT yielded some measurement errors: in Figure 6 (frames 35-43) the Figure 5 – Annotation standard deviation Hough transform detected a sudden change of lanes (which is not accurate) and, after the manoeuvre (frames 45 onwards), a bias was measured by the SUT Figure 6 – Final error computation using an ML SUT algorithm erroneously.
4. Conclusion ▪ Two SUTs were evaluated by the framework: computer vision with Hough transform and machine learning with LaneNet.
Figure 2 – Test framework for Lane Keep Assist Software-Under-Test
The framework can invoke functions, classes, and methods of Python scripts and consequently host an algorithm execution, passing parameters in and results out for any dataset given. The framework emulates test protocol from EURO NCAP specifically for Lane support Systems.
▪ Minor adaptations to the original code is needed when used by the framework. Therefore, these modifications would unload the CPU bourdon of image display, debugging, and graph plotting from the core algorithm implementation. ▪ Creating a image-set with calibration information helps to compare results in metric units.
Figure 3- Example of test case from Euro NCAP assessment protocol
▪ The repeatability of scenarios bring confidence in the detection where bias and offset can be detected. For future work, more of EURO NCAP scenarios would be beneficial to be recorded.
Figure 3 shows an example of a test manoeuvre of a lane change scenario. This work recorded, annotated and tested a real-world image-set, complying with EURO NCAP protocol.
▪ The framework can ingest easily other image-sets, although the implementation of the annotation style and accuracy measurements is pending to be developed.

Email: s0022769@atu.ie
Student ID: S00227697
Introduction: Given the increase in thefts in the last ten years and the high number of
new companies that offer security services, the idea of this project is to create an intrusion detection system that is different from the rest of the market, using hidden systems under the ground, in addition, the owners will have access to the monitoring of the state of the properties through a mobile APP.
Aims of Study:
Design and create an Intruder Alarm System in which security prevails over any other factor, hoping that the intruder or thief does not have the capacity or resources to detect and disable the installed devices. This system complies with Intruder Alarm System (IAS) standards.
Methodology:
• Research:
Investigate the behavior and installation of each of the mechanisms and, in particular, of the two basic components of the project, which are the strain gauges and the Wi-Fi module, generating modifications in the execution of the project.
• Hardware: - Arduino UNO: Controls the system components by running the main program, taking the signals from the sensors and sending the responses to the LCD monitor and the APP mobile via Wi-Fi. ESP8266 Wi-Fi: Establishes communication and transmitting data between mobile APP and microcontroller via Wi-Fi.
-Lcd Monitor with an I2C: I2C has been integrated to simplify the installation and take more free ports in the microcontroller. Show the live values of the measurement sensors.
The application has been developed in MIT App software, establishing serial UART communication between the Arduino and the App. It displays the sensor measurements in realtime, updating every 10 seconds. When the strain gauge detects a value greater than 15kg or the ultrasonic sensor undergoes distance variation for two or more seconds, an alarm signal is triggered in the app. The alarm will disappear when the Reset button of the application is pressed.
The App:
Prototype: All schematic project has been developed in Proteus and tested with IDE Arduino, as shown in the image below.
- Strain gauges: Four strain gauges have been used to make a Wheatstone bridge and detect intruders by a pressure change on them.
Results: • The developed system performs the task successfully. It is capable of detecting the intruder with one sensor or both simultaneously. Working in redundancy makes the system more robust and secure. • Working with Wi-Fi means that you can connect the module almost anywhere due to the large number of existing networks.
• Software and Flow-Chart: - Load Cell Click(HX711): It powers the Wheatstone bridge and amplifies and digitises the signal, which, together with the microcontroller, allows us to know the weight.
Conclusion: • The Wheatstone bridge allows us to measure resistance changes in strain gauges to allow accurate measurement of small resistance changes and to compensate for resistance variations due to temperature. • I have used ESP8266 to provide Wi-Fi connectivity to the project with Arduino. For the data transmission, for data transmission, a voltage division at 3.3V between Tx from Arduino & Rx Wi-Fi module; if not the Wi-Fi module can burn out. • It is recommended to use a much more efficient ultrasonic sensor so that the margin of error of 5 cm is reduced to the maximum.
- Ultrasonic Sensor: used to detect a change in measured distance.

Introduction
This project will automate a safety system for use in the railway industry. When a group is working out on a railway track, they depend on a colleague to watch out and alert them to approaching trains. This automated system improves this safety system by providing backup.
Aim
The aim of this project is to develop an automated device that will detect approaching trains using a vibration sensor in advance of their arrival at a work site. A microcontroller will process the information input from the sensor and output a signal through a serial port to a HC-12 Radio Frequency Transmitter. This will transmit a signal to a paired receiver at the work site. This will cause a second microcontroller to output an alert to the workgroup with an audio and visual alarm prompting them to move to a safe position prior to the train's passing of the work site.
Methodology cont’d Build
To test the functionality of the components and circuitry a prototype was built on a breadboard. This allowed for ease of modifications to hardware and software. When functional testing was complete a PCB layout was designed. The components and circuitry were then built on the PCB. Inputs and outputs were connected to peripheral devices and further functional testing was carried out.

Further development
➢ There is potential to develop this project. Initially, the receiver unit can be modified as a portable unit in an armband form ➢ At the moment the train radio system used in Irish Rail for communication between the driver and the signal control person operates on the UHF band. It would be possible to develop the receiver unit to receive a message from the train radio mobile units transmitter, triggering an alarm. This would eliminate the need to attach the transmitter to the rail for each work site

Thermal Camera for 3D Printing
Name: David Keane Email: s00207393@atu.ie Supervisor: Mary Carden Student No: S00207393
INTRODUCTION
AIM OF STUDY
METHODOLOGY
3D printing is being adopted by more and more companies involved in manufacturing each day due to its costeffective process and versatility. A common denominator required for this printing to work is heat. The introduction of heat to this process brings with it a new set of challenges such as providing safety to any persons involved in the process.
The main aim of this project is to provide operators, cleaners, or any persons who might come in contact with a robotic 3D printing cell, a means of safely checking that the cell is safe without putting them in a danger by having to enter the cell. This will be achieved by communicating to the user, the highest internal temperature of the cell from a safe viewing area outside the cell guarding.
There are three main stages of this project that allow it to work:
HARDWARE For this project, the primary parts that are integral to its operation are: Raspberry Pi 3 Model B – Two of these are used to provide control of the other devices in the project and communication between the controllers.
SOFTWARE The raspberry pi allows the use of multiple programming languages but for ease of use, versatility and abundance of resources available for the different components, Python is the main language that was chosen for this project. On the Raspberry Pis, programs have been imported and functions created to control the following aspects of the project: • Control of the thermal cameras, to establish communication with them and read live data as required. • Control of the TOF camera, establishing communication and acquiring live distance data.
• HMI control through the display monitor including a heat map and key information about the cell. • GPIO control and control of indicators. Supplementary software used includes: • I2C communication • TCP/IP communication • KRL (KUKA Robot Language) • EthernetKRL
MLX90640 Thermal Camera – This infrared camera is used to gather temperature data from inside the cell. ArduCam Time of Flight (TOF) Camera – This camera is required to obtain a distance to the heat source that will be used to calculate the temperature at the source.
WIMAXIT Raspberry Pi 7” Monitor – This monitor provides the primary method of HMI between the sensor system and the user. Additionally, a collection of minor parts have been used for mechanical protection, efficiency of use and aesthetic appeal. They are as follows: • Two 3D printed cases • Extra connecting cables and wires • Power supplies for Raspberry Pis • Two USB type A bulkhead connectors • Raspberry Pi IO terminal breakout
1. Obtain raw data from sensors and use this to adapt the robots position to place the highest temperature point in the cell in the centre of the field of view of the sensor system. This is done by changing the angle of the sensor system until both thermal cameras read the same temperature from the source. 2. Using the distance to the heat source obtained by the TOF camera, the device will calculate the temperature at the source inside the cell. Rigorous testing was carried out to create a function that will produce an accurate temperature relative to the distance it was obtained from. 3. The newly obtained data is then transmitted to the other Raspberry Pi, connected to the display monitor, safely outside the cell. 4. Key information will then be displayed to the user through the HMI regarding the current highest temperature in the cell and whether entry to the cell is safe.
RESULTS & CONCLUSIONS Ultimately, I was able to produce a device capable of accurately measuring temperatures during a 3D printing process and relaying this information to the user safely. Although the project performed well and met expectations for a reasonable price of approximately £200 improvements could certainly be made. If this project was to be turned into a viable market product, resources and time would be required to bring the device up to safety standard requirements and be able to market it as such.

The Accelerometer, buzzer, led’s were sourced online. The Arduino Uno I had already from previous year’s lectures. The enclosure was sourced also online.
3 Axis and Gyroscope sensor
Software:
The 9 Volt battery connector.
This device will also be portable, small in size, and lightweight and while having accurate measurement results.
Research: Most smartphones/tablets come with many standard programs/apps, but not all come with an app that can measure whether an object is level or not. Apple products such as iPhones & iPads come standard with an app called measure, allowing users to use the device as a spirit level or a tape measure by using augmented reality (AR) technology. You can gauge the size of objects, automatically detect the dimensions of rectangular objects, and save a photo of the measurement. However, on some android devices, the user must download a measuring app which may take up too much memory on their device, by developing this project, it will mean that any person will not need any smartphone/tablet device to operate or use this levelling device.

Results:
Design/Planning: Selecting the appropriate hardware. • Develop schematics, PCB layout, and a software flowchart. • Development of an efficient software code.

If the object isn’t straight then it will light a red led which depends on if it’s minus or plus 0°, it will then sound from a buzzer to alert the user however if the object is straight, it will display a green led to alert the user.
Conclusion: Overall I am happy with my project, it was inexpensive to manufacture with the end cost totalling £50.84 or €57.66. During the project, I use the skills I learned from the ATU and especially Mobile Apps programming as I learned how to program using the Arduino IDE software.
I have tested the project and the results were When I held the breadboard with the sensor measuring between 0° and 1 ° which is displayed on the serial monitor at the Xaxis tab then the Green LED which indicates the sensor is level which is the result I want to achieve. If I tilted the sensor clockwise and the degrees reading was outside the level tolerance as above then the positive red led did light up and the buzzer did sound which is correct. Likewise, if I tilted the senor anticlockwise, the other Negative led will light up. For the two red led’s I have the tolerances set up as follows, Negative Led -1 ° to -90 ° Positive Led +1 ° to +90 °
Future Improvements:
For future improvements, I would like to install an LCD (Liquid Crystal Display) and output the results from the x-axis displayed on the screen. I would program the code to generate the code from the Y-axis and output the results and be able to have an led on from resulting both from the X and Y axis measuring angular degrees between 0 and 1 to record them as been level.

INTRODUCTION
• The carbon footprint and environmental impacts of crops imported from tropical climates are a growing concern for environmental sustainability. The main barriers to growing crops domestically is the lack of daylight for half the year and the cold climate. • A potential solution to this is to use greenhouses to grow crops not normally suited to the Irish climate, this would enable crops not normally suited to the Irish climate to be grown locally rather than be dependent on imports that have a high carbon footprint and are increasing in cost.
AIMS
• The aim of this project is to build an automated climate control system for a greenhouse. • The system will focus on light level and temperature as the key factors needed to be controlled. • The system will monitor environmental conditions for a greenhouse and provide an automated response to changes in environmental conditions to maintain an ideal environment for the growth of the plants.
METHODOLOGY
• The core of the system is an Arduino Uno controller. • Monitoring of environmental light levels was achieved using an analog LDR light sensor, based on the measured light intensity. An array of LED lights can be automatically enabled via the SPI interface. • A Temperature sensor is connected to the Arduino via its I2C interface. Based on the detected temperature levels a cooling fan or a heating element can activated to either heat or cool the system, additionally, status LEDs are used to indicate if either output is currently active.

Student ID: S00220145
Introduction The project aim is to detect the gas leakage from our home gas appliances and get a notification by buzzer and SMS to our phone number. Also, switch ON the exhaust fan. This project uses an MQ2 sensor to detect the combustible gas and it interfaces with the PIC microcontroller. The microcontroller read the values from the output of the sensor and if the value is above a certain threshold level the system will generate an audible alert using a buzzer and display the concentration of gas leaked using the LCD and activate a relay to control the external devices like exhaust fan and gas supply valve. Also, send a notification SMS to the user/authorities’ phone.
Aim of Study Apply the knowledge I learned from the course in the practical field, especially the PIC microcontroller interfacing with other devices like LCD, Relay, Buzzer, and serial communication with GSM module.

Build & Testing The program is written in MPLAB IDE and burned to a PIC microcontroller using pickit3 and the components are placed on a breadboard and connected them using connecting wire as per the schematic diagram.
Pickit3
When the gas leaks, the controller gives a notification through Buzzer Activation, Relay Activation, LCD, and SMS through the mobile network using a GSM module
After testing on a breadboard, components were soldered to PCB and applied the gas to the sensor from the cigarette lighter. The sensor is connected as an input to the microcontroller and the ADC value is higher than the threshold the controller outputs activate. And LCD will display the Alert message & PPM value of the gas leak.
Conclusion We can change the sensor with other series MQ sensors for detecting the various type of gases. To display the PPM Value needed a small modification in the program. Early gas leak detection will help to save human life, property, and the environment.

Electronic Engineering Introduction
This project was created to review the potential for facial recognition in a security system using a convolutional neural network (CNN). Two different systems were created for comparison. One employs the Haar Cascade classifier for face detection and Local Binary Patterns Histograms (LBPH) face recognizer for facial recognition, the other utilizes the Multi-Task Cascaded Convolutional Networks (MTCNN) for face detection and InceptionResnetV1 with the VGGFace2 pre-trained model for facial recognition. For the security aspect of the project, if a recognized face, which is defined by a set threshold, is detected it will open a symbolic door, if an unknown face is detected it will keep the door closed and send an email to the owner containing a photo of the unknown face.
Facial Recognition Security System Using Convolutional Neural Network Student name: Brian Troy
Supervisor name: Sean Mullery
Email: S00219528@atu.ie
Student ID: S00219528
Results
In the charts below we see the results over 150 second window. As expected, the model using the MTCNN faired much better than the model using Haar Cascade for the application of a security camera. The Haar Cascade model never got over 60% match to photos in dataset. For accuracy, the MTCNN had a higher detection rate, where false detections can lead to unauthorized access and deny access to legitimate users. The MTCNN was more robust also which lead to fewer false negatives and positives in varying light and when face angle and expression varied. It also had better detection of multiple faces which would be advantageous in a busy environment.
Conclusion
As the number of images in the dataset increased the training time and model accuracy increased. At the end of the experiment despite the MTCNN being a betterperforming model in most metrics, there were some important trade-offs discovered. The Haar Cascade model was generally faster, making it more suitable for real-time applications, and also uses less computational resources, so would be more likely to run on an embedded system where power and memory may be limited. The deep learning approach of the MTCNN is far more complex and required more time to train a new face, so maybe less favourable to use in the real world. Considering the accuracy, robustness, and additional facial landmarks provided by MTCNN, it is a better choice for a door-opening security system. However, if speed and computational resources are significant concerns, Haar Cascade can be a suitable alternative, provided that you are willing to accept some trade-offs in accuracy and robustness.
Raspberry Pi 3B Trained without hat/glasses
Post training with hat/glasses
Methodology
Using Jupyter Notebook on a laptop and on a Raspberry Pi, the Python code was inputted and executed. The internal webcam with 720p resolution and an external 1080p webcam was used to compare. For data collection, 200 photos of users were taken with faces in various orientations, various lighting conditions, and backgrounds to create the dataset. For the Open-cv model trained with a Haar Cascade classifier on the pre-processed dataset. The classifier was trained to detect frontal faces with various scaling factors and neighbor thresholds to optimize detection performance. The trained Haar Cascade classifier was used to detect faces in input images. Detected faces were then matched against a database of enrolled faces using template matching or eigenfaces technique. Access was granted if a match was found; otherwise, it was denied.

The MTCNN model from the facenet-pytorch library for face detection was used to detect and extract faces from input images, ensuring accurate localization and alignment. Utilizing the pre-trained InceptionResnetV1 model from the facenet-pytorch library for facial feature extraction. The features were then matched against a database of enrolled faces using a cosine similarity metric. If the similarity score exceeded a predefined threshold, access was granted; otherwise, it was denied.

Introduction As video surveillance is rapidly gaining popularity, many video surveillance applications urgently need a longdistance, user-uncooperative, and fast identification technology to quickly confirm the identity of people from a distance and to achieve intelligent check-in.
Aim This project is based on deep learning multi-scale face extraction and recognition technology, through which the face recognition system can capture and store face images, automatically sense people entering the recognition range, and trigger the system to work. The system supports dynamic face capture, capturing face images of people walking normally without the need for them to stop or make specified movements. The system supports the capture of multiple faces at the same time and can complete the comparison of face images from the camera with the face image library in a short period of time for time clocking or passing. Administrators can also log in to the system to check personnel sign-in and control face information intelligently.
Methodology Data acquisition: Face images are captured by the camera. A dataset is constructed, and data pre-processing, such as noise removal, resizing, and orientation is performed.
Face detection: Using the Retinaface face detection algorithm, the captured face images are detected and face regions are extracted. The detected face images are also aligned. The effects of the pose, lighting, and other factors are eliminated.
Feature extraction: Using the Facenet face feature extraction algorithm, feature points or feature vectors are extracted from the face image.
Model training: Using the PyTorch framework, the Retinaface and Facenet models are built and trained. The Retinaface model first needs to be trained in order to detect and extract face regions from the input image. The face regions detected by Retinaface are then used to train the Facenet model to extract face features and train for classification or regression tasks.
System integration: The trained model is integrated into the attendance system and connected to the camera, database, etc. to achieve the face recognition attendance function.
Results Attendance recording: When a face image is input, the system will perform face recognition on it and compare the recognition result with the employee information in the database, if the match is successful, the employee's attendance information will be recorded.
Conclusions and Future Perspective
The system supports multiple face detection at the same time, personnel does not need to do any action, they just need to pass by the camera area to complete the attendance clocking.
Administrators can log in to the back office system to check in, add and delete face information, and view the monitoring screen in real time.
The final results show that the system has a low recognition rate and false recognition rate, which meets the requirements of practical applications. And the system can accurately identify employees and record attendance information in real time, realizing sensorless attendance and improving management efficiency. The development direction of future sensorless face recognition attendance system may include 1. Multimodal recognition technology: Integrating multiple biometric recognition technologies such as voice recognition, body temperature detection and electrocardiogram to achieve comprehensive attendance supervision. 2. AI intelligent analysis: Combining artificial intelligence technology, through big data analysis and deep learning, it helps enterprises to better manage employee attendance data and improve employee performance and enterprise efficiency.

With the development of information technology, cars are becoming more intelligent and automated, and autonomous driving technology has become a new hotspot for scientific and technological research worldwide. This project realizes a smart car that can detect lane lines a n d s t o p w h e n a ‘STOP' sign is recognised.

Student Number: S00202751
Methodology Continued Recognition of ‘STOP’ Signs
This was replaced by another approach, the Haar cascade classifier. It works in a similar way to a regular Convolutional Neural Network (CNN) with a feature map. It is high efficiency and can be performed quickly for realt i m e o b j e c t r e c o g n i t i o n . Load Model
Results
Start the car and it will automatically start moving forward. At the same time, the camera starts to fetch images and the Raspberry Pi streams the images captured by camera to the server, which receives the video and starts to detect lane lines and stop signs. When the trolley detects a 'stop' sign while moving forward, it sends a stop signal to the Raspberry Pi and the trolley executes the stop procedure.

The hardware in the project uses a Raspberry Pi (4B) based smart car which is made by SunFounder. The car carries a camera which is used to capture live footage. The Raspberry Pi acts as a server to transmit the images captured by the camera. The project focuses on how to detect lane lines and recognise ‘STOP’ signs.
Methodology Continued Lane Detection:
Lane line detection is a fundamental module in autonomous driving and is almost impossible to achieve based on traditional image processing methods, so I use Ulrta-Fast-Lane-Detection - which defines lane line detection as finding the set of lane lines at certain row positions in an image, that is based on position selection in the row direction, and classification (row-based classification). Although the detection is more effective, there are problems that cannot be solved . Because of the large calculation involved in classifying each p i x e l p o i n t i n a n i ma g e , the result is a slower pace.
Conclusions and Future Perspective
The project is at Level 1 -Driver Assistance (SAE Levels of Driving Automation), which realises the recognition of lane lines and road signs. It has the potential for practical use, but it also has limitations. These include, for example, slow processing speeds, lagging due to video frame build up, lack of pixilation in the images acquired by the camera, and the recognition of a single road sign. Based on these drawbacks and shortcomings, I will continue my research in the future from the following p o i n t s :
Replace with better camera facilities. Update the code to make the acquisition smoother. Increase the number of road signs identified. And others …

Methodology Waste classification identification Garbage sorting recognition is implemented using the YOLOv5 model. I generate the model file by training with PyTorch, write the code in Python and call the YOLOv5 model on the Raspberry Pi for garbage classification recognition. Then, the YOLOv5 model is used to detect and return the garbage category and location information. Finally, the corresponding text descriptions are displayed on the screen according to the detected garbage categories. Face recognition unlocking Face recognition unlocking is implemented through Baidu Smart Cloud API. I write code in Python to call the API interface on Raspberry Pi to implement the face recognition function. By using the face detection interface of Baidu Smart Cloud API, the face in the video stream is detected and the face location information is returned. Then use the face recognition interface to recognize the detected faces. If the recognition is successful, it is unlocked; if the recognition fails, it cannot be unlocked. Project Flow Chart

Conclusions and Future Perspective When using the Raspberry Pi for face recognition unlocking and garbage sorting, we found the project to be highly practical and feasible. I proved that the system can be unlocked securely by face recognition and also can effectively identify the type of garbage. Therefore, the project can provide a practical solution
for communities or schools that can improve security and environmental awareness. The project can be further improved and extended in the future by: 1. More types of garbage sorting can be recognized. 2. Using more advanced face recognition technology to improve the accuracy and speed of unlocking. 3. Integrating the system with the cloud for data storage and sharing.

Conclusions and Results
First, use the 18650 battery to power the car and Raspberry Pi, and then use the driver to use the Raspberry Pi to drive the motor of the car. Then link the camera to the Raspberry Pi. According to the visual following system, the car will follow. If the face recognition is successful, the control interface will be displayed, and the user can choose the function in the interface. If the recognition fails, another interface will appear, which will teach users how to use and create an account.
Face recognition module Face recognition can quickly identify the input face. Due to the running memory problem of Raspberry Pi, the number of camera frames per second is too small, resulting in jams. And in the test, it was found that the success rate of face recognition for Europeans is higher than that of Asians. Trail track

You can choose the functions in the system. For example, you can choose to let the car follow you, so that you can free your hands. You can also let the car be sent back to the storage area, and then face recognition again to take out the items.
You can click the corresponding buttons separately to solve the problem you want to understand, and we will introduce our system and how to use it in video. You can also inquire about the contact information to make valuable suggestions You can also play a beautiful piece of music. There are more functions under development.
Methodology This project is based on Raspberry Pi embedded system.I used SUNFOUNDER Raspberry pi car-v of hardware. First of all, I use face recognition to identify the user, and then send the saved items to a fixed place for unified storage. When picking up items, the same method is used, and the advanced pedestrian face recognition is carried out. In the face recognition module, I using dlib's state-ofthe-art face recognition built with deep learning.It identifies the three parts of the eye, nose and mouth to determine the face. In the car running module, first, I used computer vision to follow the items. Second, I used IR sensors for line tracking. In addition, I also added music players and videos to explain how to use them. And I have added a control interface to my system, and users can choose to use the function.
If you choose to listen to music, you will get a music player that can play and pause.
Music player I made a simple music player that can play a piece of music, and Operation box you can control pause and play. I made an operation box, which can help users choose the functions they want, and is more conducive for users to use the whole system.

S00202774
Introduction Sorting trash is boring work for everyone, but it's still necessary to do to protect the environment. This project aims to solve this problem, by modifying the trash can in your daily life, it can sort the garbage automatically. You can simply put the trash in front of the camera, and it can recognize the type of trash, and send the trash to where it should stay. The aim of this project is to help everyone to sort their garbage more effectively, and it also can help to build a greener planet, with proper trash sorting, most trash will not just go to waste but have better usage.
Methodology In this project, after the research progress of the system, the core part of the system is the recognition process of the video captured by the camera. Therefore, proper use of an effective image recognition model is the most important problem that needs to solve. The Object Detection Model for trash classification In this project, we consider using the state-of-the-art image recognition model YOLO-V4, in real-time video recognition, it can respond fast, and make this project possible. The image shown below is an example of the trash detection progress and a result.
Results After developing the project, a concept was developed for this trash bin project. It contain the following parts which shown below.
It comprised of the following steps using this smart trash bin system The user will put the trash in front of the camera, and wait for the recognize. The screen will inform the user what should they do. When recognition is completed, the system will tell the user to put the trash, and the user can put more trash or just leave.
Conclusions and Future Perspective
The System Overview This system will stream the video to the server, which is capable to run the model faster, and the server will return the recognized result, and this will only happen when something moves to the front of the camera. A step motor will tilt the board inside of the trash bin, and when the trash fell off, it will fall into the correct type of trash bin. There‘s also a screen that can tell the user what type of trash is in front of the camera, and when should they put the trash in the trash bin. The pictures below illustrate how this process works.
This project provides an effective solution for trash classification and sorting problems. It's cheap and easy to implement in the real environment. Considering the limit of the system, like the network problem, and limitation in kind of the trash it can recognize, then the following future perspective is: Use light weight model which can running in local. Expand the dataset to more type of trash Add the ability to deal with hazardous waste And More…

3D printed modular Kiosk Design: o We would like to have an original modular Kiosk design printed and with hardware installed. Improved Kiosk Interface: o We would like to have a touchscreen and publicly usable interface to allow both customers and agents to interact with the kiosks. Improved Integration of services: o In a future revision of the app, we would like to have greater integration of services such as payment and google analytics. Better integration between Kiosk and App: o Currently the kiosk and the app both communicate with the same Firestore database independently. In future product revisions, we would like to have greater integration between the two components to improve the range of features and interactivity. improved payment plans and premium features: o A greater refinement of payment plans, more premium umbrella options and services would be a nice addition to our product.

RekogLock
Our Goal The goal for this project was to allow for physical security within an institution utilizing modern technologies to log and monitor users entering a secure room
Meet the team: Craig Lawson – Computing (Networking) Jack McElroy – Computing (Networking) Gatis Berzins – Computing (Networking) Sean Dowdall – Computing (Software)
About us: We are a group of 4 programmers who decided that security within the college could use a more secure and administratively friendly locking mechanism with a large amount of scalability.
Craig Lawson, Jack McElroy,
Supervisor: Kevin Peyton
Sean Dowdall, Gatis Berzins
PRJ300
Project Overview Angular Website The aim of our project is to allow for secure access to certain rooms with sensitive data that can be accessed via an authorised Angular website. Research: For the research of this project we analysed many different types of security systems and wondered what could be made with more modern and secure technologies Technologies used: • Angular • Amazon Web Services -DynamoDB -Rekognition -S3 bucket -Lambda • Raspberry Pi
The Angular website allows authenticated users to securely login and view data logged by the Pi after taking a photo. The data is displayed in a table that can be filtered What can be viewed on the site: • Date • Student Number • Full Name • Time • Match percentage (of face) • Room (Location) • IP and Mac Address • Pass/Fail
The website will also allow you to initialize users for the lock
How It Works Step 1: Press button Step 2: LCD informs you that Pi is taking photo Step 3: Face is analysed and result is displayed on the LCD Step 4: Door is unlocked for 5 seconds and image is sent to database Step 5: Result is logged on authenticated website which dynamically displays attempts

Computing & Electronic Engineering Project Overview
Meet the Team Members: o Emmet Carroll – Game Development o Tommy McKee – Game Development About us: We are two Games Development students whose first year of study at IT Sligo was all online. We didn’t have the opportunity to attend the campus for an open day or class until our second year. We have developed this application to aid future students that may not be able to attend a physical open day.
Technologies Used
The aim of the UniVRsity project was to develop a scalable virtual open day for the ATU Sligo Campus. The virtual campus will consist of faithful recreations of key areas of the ATU Sligo Campus for the user to explore. This is built in the Unity Game Engine with models being built in Blender.
Core Business Idea The core business idea of the project is a marketable Virtual Open Day Currently, ATU Sligo offers a Virtual tour in the form of 360˚ cameras. We have repurposed these cameras in UniVRsity so the user can directly compare the virtual campus to the real one. The use of Playfab means that the UniVRsity administrators cant get information on the users that register such as last login, registration date and county signed in from.
Software used: o Unity o Visual Studio 2022 o Blender o Audacity o Playfab o GIMP o Trello o Microsoft Teams o Github o Google Drive o Discord
Future work If we were to continue to develop UniVRsity into the future there are a few features that we would implement. Seeing as it’s a scalable project, we could easily add more areas or even different college or university campuses. We would also add: • Artificial Intelligence • Chat Bot features • Multiplayer • Interactable Props • Downloadable PDFs • Reward for all collectables

Problem:
Back-End:
Solution:
Front-End:
• The college system for tracking student marks and attendance has multiple issues. • Teachers are required to enter marks twice for each student, and sometimes the system fails to save the marks correctly. • The system's complicated design has resulted in complaints from teachers. • Build a web application that will record student marks and attendance. Also, one more page for parents to track their child behavior.
Features:
• Teacher able to record student marks and attendance. • Parents able to see their child behavior. • Admin able to register users. • Head of department able to view students marks and attendance. • Students able to see their mark exams.
• I have chosen to use Express js as back-end • Express.js is a popular and efficient choice for back-end development • Express.js is a fast, flexible, and minimalist web framework for Node.js • Express.js is ideal for building backend applications. • I have chosen to use Angular as FrontEnd. • The front-end of a web app displays information and handles user interactions. • The front-end is responsible for creating the user interface. • Angular is a popular and powerful choice for front-end development. • Angular is a JavaScript framework for building dynamic, interactive web applications. • Angular provides a comprehensive set of features for creating complex, highperformance web applications.
Database:
• I have chosen to use Mongo DB as my database. • MongoDB is a popular and efficient choice for databases when using Angular and Express.js. • MongoDB is a document-oriented NoSQL database designed for scalability and performance. • MongoDB stores data in a flexible, JSON-like format that is easy to work with and integrate with web apps.
Future Work:
• The website should be optimized for mobile devices to allow users to access it on-the-go. • Up-to-date academic calendars, course schedules, and announcements about important events and deadlines. • Incorporate social media features to encourage engagement and interaction among users. For example, a direct chat between the teachers and parents.

1. Overview
The aim of this project was to develop a car companion application for young drivers to improve their fuel economy and have a better understanding of how to better maintain their car. OBD-II provides diagnostics on different readings including RPM, Speed, and Fuel levels from the car’s computer. These diagnostics can be requested and have values returned using an OBD-II scanner. This application combines insights built from the car’s computer and a place to record and keep track of maintenance on their car. • Drivers can view live data being read in through Bluetooth from their car into their phone. • Drivers can view graphs and dynamic advice about their driving habits based on different readings • Drivers can view insights about their fuel economy • Drivers can record and view past maintenance jobs on their car

3. Research
I bought a scanner to interface with my car’s OBD port. I then built test applications to understand how to interpret the data being read in from the scanner.
5. Development
It was necessary to use external libraries for both the OBD II interface and the charting aspect of the application. Having researched the libraries and making demos of each of their functionalities, I was able to implement more functionality such as fault codes from the car, and time intervals for the charts.
4. Architecture
I decided on Google Firebase Firestore for my backend, so that maintenance recorded could be stored on the cloud and read back down to the user’s phone. The main application was developed in Java in the Android Studio IDE. A Bluetooth service connects the application to the scanner so that readings can be requested.
2. Planning
This project was developed using agile development methodologies. Each week, new functionality would be implemented by prioritising user stories. Using GitHub for source control, I was able to implement semantic versioning for better project management.
Screenshots of the application
6. User Experience
I followed UX principles for the application’s development. I mapped out the application’s interface using wireframes, I then applied the UX principles of perceivability and performed usability tests.
7. Testing
Once the application had its functionality working, unit tests could be carried out to perform final tweaks to the interface and edge cases for the business logic.
8. Conclusions
Through careful planning and adopting the agile development framework, I was able to fulfil the user stories that I had set out initially that were feasible. It was a very interesting experience to try to work with hardware, a car in this case, as opposed to a traditional software stack. The biggest takeaway from this project is that strong planning and iterations of that plan can lead to greatly enhanced productivity for such a project.
9. Future Development
For the deployment of the project, application to the Google Play Store is required as well as architecting the product for authentication

SocialBox Ethan De Guzman
S00199053
S00199053@atu.ie
Supervisor: Kevin Peyton
Overview:
Front-end:
• SocialBox provides an easy solution to analyze social media trends and user sentiments. • The application uses Twitter to perform realtime sentimental analysis and we are looking to expand the service to other social media platforms in the future. • It provides user-friendly visualisations so our users can easily gain insights from the social media data. • The ability to schedule the analysis was also added as a feature so our users can check if the public’s opinion has changed over a certain period. • The focus of the application is on the marketing and advertisement department. With the help of sentimental analysis, businesses and organizations can manage their brand reputation in a more efficient and effective approach. • They can understand whether how certain choices affected the brand or how well the public’s opinion received a particular product or service released by the company.
• The web application was built Angular – one of the most widely used frameworks in the industry. • It also uses common frameworks like Bootstrap and Bootstrap Icons to help elevate the design of the web application • For data visualizations, SocialBox uses the popular charting library ChartJS. • The web application is hosted using AWS Amplify and all user authentication/authorization is handled using AWS Cognito.
Back-end: • With the help of microservices and a cloudfirst approach, Amazon Web Services offers several different technologies that can be used for the back-end. • CRUD operations are called using API Gateway and executed using AWS Lambdas written in Python runtimes. • For data storage, a non relational database is perfect for the schema-less data coming from Twitter. The service chosen was DynamoDB. • AWS Sagemaker is used to host and deploy the sentiment model. • For scheduled jobs, SocialBox uses the AWS Eventbridge service alongside AWS Lambda functions. • The back-end is also deployed using a CI/CD approach.
Future Features: • Ability to download the different visualization charts and graphs. • Utilize other social media platforms such as Facebook, Instagram, Reddit etc. • Real-time alerts such as generating summary reports every week and emailing the report to someone’s email.
Learning Outcomes:
• Increased knowledge & experience on working with Artificial Intelligence models, specifically sentimental analysis models. • More experiences gained on being a full stack developer. • Improved proficiency on working with AWS services. • Gained insights on creating and interpreting visualizations charts and how appropriate they are depending on the data.

Technologies Implemented
Introduction There is a gap in the market for the sale of livestock digitally. This has a potential user base of 137,500 farmers in Ireland. The product would be easy to adapt to work outside of Ireland in the future with minimal changes.
Aims The aim of my project was to create a mobile application that would act as this digital marketplace, as a part of this, I planned for the application to include the following: • User profiles connected to online databases. • Image recognition for detecting and identifying livestock. • Fully integrated financial transactions. • Statistical graphing • Chat • Admin features
There are several technologies implemented into the application. These technologies include: • Firebase Database and Authentication – This technology was chosen because it allows for the storage of data and linking that data to established accounts. This technology allows for users to chat. It also allows for users to be created and deleted within the application • Stripe Payment Services – Stripe was implemented because it is a developer friendly service that allows for smaller users and businesses to work with it without requiring a set-up storefront, it was also chosen due to it having built-in security that is stronger than what I could provide • Custom Vision Services – This service was decided upon because it is an open and free to use version of machine learning for image recognition
• Oxyplot charting – Oxyplot was used because it is the only fully able to be integrated free charting service for Xamarin
Results and Future Features The project managed to complete all of the aims that it set out to accomplish. It is able to make use of machine learning to recognise and deny spam or false uploads. It can perform payments globally with security. It has a built-in self-updating graph of sale. It has functional profiles that allow for it to connect to an online Firebase Database for Authentication, storage and chat. If I were to continue this project I would add video recognition and expand it to all other livestock markets
User Interface The design of the user interface was to ensure that it would be clear and easy to read all of the information on the screen. This is the main sales that is called within the application.
On the purchase screen, you have the option to purchase the animal or chat to the seller.
This page automatically updates with each new animal that is listed within the application.
This has an upscaled image of a cow so that even if the uploader uploads poor quality images the animal is recognisable.
Tapping on an animal takes to the purchase screen.
This screen provides an in depth description of the animal
This is an image of a graph that is generated based on the sales that are performed within the application. The graph will automatically update with each sale that occurs within the application.

That Moon's Got Monsters A procedurally generated dungeon crawler Student name: Andrew Casey Student number: S00200841
1. Overview
Procedurally generate content for replayability
Student email: S00200841@atu.ie
2. Planning
Supervisor name: Veronica Rogers
Plans for the project were laid out and the topic of procedural generation was chosen as a focus to base the project on. Fight Enemies. Find Portals to Proceed.
Unity was chosen to facilitate the creation of the game. The idea was to create a 2D game that would focus on the ability to reuse assets to create a fresh new experience in each playthrough.
3. Production
GitHub was decided upon to facilitate the version control of the project. Weekly Standups were planned to discuss workloads. A Done, Doing, To-do process was discussed at these meetings, and Trello was then used to visualize the workflow.
4. Product Testing
5. Conclusions
Product testing was done when the product was considered ready to release. Focus was given to User Interfaces to improve the quality of the game.
Procedural generation can be quite difficult to deploy correctly but the payoff for having procedurally generated content for replayability is worth the investment.
User Experience (UX) was employed by having testers test the game and give feedback on their experiences to help improve future updates.
The ability to create dynamic content is beneficial for small development teams. It allows them to focus on more aspects of the game they are creating.
6. Future Plans • Animations • Increase Enemy Variety • Release on more platforms • Boss variety • Increased item collection count • Increase room variety

Overview:
Front-end:
Development:
• The main aim of this project is to create a platform for groups of friends to effortlessly find times to meet up. • Users can create groups and add their friends. • Once a group is created, users can input the times in a week in which they are free to meet. ‘uFree?’ will then clearly display the slots where all members of a group are available at the same time. • Users can create custom activities for their groups. Each activity can have a name, description and a limit on the minimum members needed for the activity to take place. • Once the available times are found, users can set an activity for those times which will notify members of the group and will display on the group schedule. • For example, my group has an activity called “Golf”, I need a minimum of three people to play golf, so the app will display all times where at least 3 members of the group are available for that activity, I then select the most convenient of these time slots and set the activity, notifying the rest of my group members.
React is a widely used JavaScript library used for building user interfaces. React is quickly gaining in popularity among developers and this is a large reason for it’s use in this project, as it was beneficial for me to learn in depth. Along with React, this project utilizes Bootstrap 5 for UI design and Syncfusion React scheduler which is a library with UI components making the design of the schedule much easier.
Development started with planning the applications architecture i.e which technologies were to be used. Once they were decided, an architecture of the SQL tables needed was drafted up, this architecture changed slightly as development continued. As programming commenced, each addition was tested before moving on to the next, this made for smooth progress as I was never bombarded with errors. Testing continued to occur along with development, as sometimes adding one new feature may inadvertently break on old, previously working one. Once an idea of the UI was formed, friends and family were brought in to test its feasibility and changes were made where necessary. GitHub was used for version control and for CI/CD, once a change was made and tested, it was pushed to GitHub where it would be automatically published to the live server.
Back-end: The project uses Azure cloud services for the back-end. Data is stored on an Azure SQL Database. Data is then read and written to and from the database using an Azure functions application, written in the programming language C# on the .NET 6 framework. The functions use SQL queries to interact with the SQL database. Each function has its own URL which can be called via HTTP requests from the front-end React application, much like an API. Data can be passed with these HTTP requests. In summary, data is passed to and from the front-end React app to the Azure SQL database through an Azure Functions application.
Future Features/Development: • Messaging feature for groups. • Improved UI. • Dedicated Mobile application (Android & iOS).

S00198481
Literature Findings
Overview •
Cian Tivnan
The aim of this project was to examine the usability and feasibility of Virtual Reality for the creation of virtual workstations, particularly for individuals engaged in remote-working. Virtual workstations allow users to replace their physical office with a 3D environment and dynamic virtual screens.
•
Prior studies into the usability of VR for productivity have found that typing speed dropped significantly as users’ keyboards were removed from their field of view.
•
Developers must be aware of the difference between focal length and convergence length when developing VR UI. When reading text outside of the convergence point caused by the device screen, users may be unable to read well. Therefore, movable UI panels are essential to a good experience.
Initial Development •
An Oculus Quest 2 application was developed in Unity for the purpose of usability testing. This application would be used to perform a study to quantify the effects of various usability aids such as tracked-keyboards on typing performance.
•
Adjusting a user’s surroundings in VR led to a quantifiable decrease in heart rate and stress levels. By placing users in peaceful nature environments, workplace stress and anxiety could be reduced.
•
Users should be provided with predictable environments that replicate their realworld surroundings, offering reference to previous experiences.
•
The UI of VR applications should be clearly perceivable and stand out from the rest of the environment. The large field of view afforded by modern VR devices may distract users from important UI elements.
Development Challenges •
Numerous challenges were encountered during development – including Oculus SDK documentation, sample assets not working correctly, as well as challenges in learning to use Unity for the first time.
Research Goals •
Research was conducted to discover common pain-points and usability principles essential to a usable VR experience.
Diagram demonstrating the difference between focal and convergence points when using a VR device (Hoffman et al., 2008)
Research application in use on Oculus/Meta Quest 2 device, using Logitech MX Keys as tracked keyboard
Research Application
• A tracked keyboard is an external keyboard which is positionally tracked by the VR device via built-in IR tracking cameras. It is then represented in the user’s environment as a 3D model, giving the user better spatial awareness. In order to explore the use of tracked keyboards to improve typing performance, an application was completed which allows a user to test the effects of tracked keyboards. Research application screenshots
• The user can enter text via the keyboard, copying over sample text to perform a typing test. This test data is then recorded to an AWS DynamoDB table for storage and further exploration. • Hand-tracking is used for interaction with UI elements, with pinch gestures being used to select items in the interface. • Upon moving their hands close to the tracked Bluetooth keyboard, the 3D hand models representing the user’s hands transition into a live camera feed of the user’s hands, positioned over the keyboard object in the environment. This ensures the user can see the exact position of their hand over the keyboard, even while immersed in a VR environment.

3. Sensor Exercise Recognition
• Accelerometer readings are sent using BLE to the phone and recorded during exercise. • New readings are checked against reference exercises. • A machine learning method is used to: • Learn new exercises. • Distinguish between exercises. • Identify partially complete exercises.
4. Camera Exercise Recognition
• Uses MoveNet Lightning. • Takes frames from camera as user performs an exercise. • Checks these frames against exercise reference frames for similarity. • Does this by checking the average cosine similarity of relevant joint pairs.
5. Conclusions
• The accelerometer can accurately detect different exercises, and how well they are performed. • 2D camera pose detection is a viable method for exercise detection. • Both methods have issues that need to be addressed, such as angles and orientation. • When both methods are used together, there is scope to improve accuracy of detection of exercises with similar features.
6. Future Work • • •
Further research on the effectiveness and combination of sensory and visual methods. Further test machine learning models. Clinical field trials.

Reducing Cost, Energy Consumption & Greenhouse Gases in Ontario Municipal Roads through Asset Management & Pavement Preservation: A Case Study Department of Civil Engineering & Construction School of Engineering and Design
Student name: Evan Tunstall
Student ID: S00219537
S00219537@atu.ie
Supervisor name: John Casserly
AIM & OBJECTIVES
INTRODUCTION With the ongoing infrastructure and climate crisis in Canada, it is imperative to find any ways to reduce cost, GHG emissions, and energy consumption in Ontario municipal road construction. With Canada’s core infrastructure estimated at $1.1 trillion, it is important to preserve the infrastructure we already have.
The aim of this research is to provide Ontario municipalities with recommendations on how to reduce cost, greenhouse gases and energy consumption during the planning and implementation of road construction projects through the following objectives;
Overall, there is a general lack of data attributing to Ontario’s current infrastructure status and the progress towards O.Reg 588/17. Creating the best approach to preserve infrastructure starts with a plan, however, implementation of that plan with the proper materials and construction methods is vital. Without knowing the condition our infrastructure, it creates difficulties when attempting to provide the best method of preserving what is currently in place. In this study, we investigate how Ontario municipalities’ can combat the current infrastructure and climate crises through the implementation of asset management and pavement preservation.
Evaluate the status of road asset management plans in Ontario municipalities. Assess the condition of the road networks in Ontario municipalities. Perform a case study on a pavement preservation method. Investigate pavement preservation methods to decrease cost, greenhouse gases, and energy consumption in Ontario municipalities. Review provincial policies, funding, and municipal capital budgets and compare the allocation between pavement preservation and traditional paving methods in Ontario municipalities. Identify and measure the current pavement preservation techniques used by Ontario municipalities.

Overall the scrub seal trial compared to conventional hot mix asphalt was complete at a fraction of the cost, a total saving of $262,630 or 83% and reduced green house emissions by 93%. Scrub Seal Trial in Hamilton, ON. Follow up Road Measure Studies. Onsite application / operation process. Testing feasibility in Southern Ontario climate.
4 Interviews conducted with municipal employees working in asset management or roads. Interviews contained 16 questions regarding asset management, funding, and pavement preservation. Interviews recorded and transcribed. Cognitive maps created for each interview. Progress Toward O.Reg 588/17 Survey sent out to 43 individuals working regional municipalities within Ontario. The survey contained 29 questions regarding asset management, funding and pavement preservation. Of the 43 individuals, 18 surveys were received and analyzed.

CONCLUSION Overall, by utilizing a robust asset management plan in conjunction with a variety of pavement preservation treatments, Ontario municipalities can slowly improve the condition roads networks. Public education is vital for the success of implementing new technology into the future of road construction. Reuse, recycling and maintaining roads to last much longer through pavement preservation is integral and can greatly benefit the current climate crises by reducing GHG emissions and energy consumption within Ontario municipal road construction.

Qualitative data collected indicated municipalities understanding of the importance of O.Reg 588/17. Quantitative data suggests municipalities in the sample size all met the deadline for Stage 1 of O.Reg 588/17 and most municipalities complete Stage 2 and Stage 3. The quantitative data indicates 12% of all municipal roads within the sample size are still gravel roads. Although participants were aware of the importance of preserving their pavement, only 9% of the annual roads budget was allocated toward pavement preservation.
RECOMMENDATIONS • • • • • • •
Build upon existing asset management plans as per O.Reg 588/17 while remaining ahead of regulations. Diversify the use of pavement preservation treatments. Recognize the importance of environmental concerns when making budget allocation decisions. Utilize more federal and provincial funding towards pavement preservation and asset management. Allocate more budget towards pavement preservation and eliminating gravel roads. Provide funding for public education regarding pavement preservation. Conduct further case studies on pavement preservation treatments across all climate zones in Ontario.

The Implementation Of Building Information Modelling (BIM) in Small and Medium Sized Enterprises (SME) In The Irish Construction Industry
Department of Civil Engineering & Construction School of Engineering and Design
Student name: Joseph Finn
Student ID: S00219519
S00219519@atu.ie
Supervisor name: Colin Harte
Introduction :
Building Information Modeling (BIM) is a rapidly evolving technology that has been transforming the construction industry by enhancing the accuracy, efficiency, and quality of construction projects. However, the adoption of BIM among Small and Medium-sized Enterprises (SMEs) in the Irish construction industry is still limited. This dissertation aims to investigate the implementation of BIM in SMEs in the Irish construction industry, identifying the benefits and challenges of BIM implementation and exploring the factors influencing its adoption.
Methodology:
Aims and Objectives :
A mixed-methods research approach will be employed, comprising both qualitative and quantitative data collection techniques. The research will start with a literature review to identify the benefits and challenges of BIM implementation in SMEs. The study will then use a survey questionnaire to collect data from SMEs in the Irish construction industry to identify their level of BIM adoption, the benefits they have experienced, and the challenges they have faced. Follow-up interviews will be conducted with selected SMEs to better understand their BIM implementation experiences.
Figure 1 : The obstacles that stand in the way of widespread use of BIM in the building sector. (Ullah et al, 2019).
• To investigate the current state of BIM adoption in SMEs in the Irish Construction Industry. • To identify the barriers and challenges faced by SMEs in adopting and implementing BIM. • To assess the benefits and opportunities of BIM for SMEs in the Irish Construction Industry. • To propose strategies and recommendations for promoting and supporting BIM adoption in SMEs in the Irish Construction Industry.
Why do you think companies are reluctant to using BIM ?
Do you agree Culture is a barrier to implementing BIM ?
Do you agree Insufficient Government Support is a barrier to implementing BIM ?
Do you believe that Main Contractors should be providing BIM training to their Supply Chains ?
Do you agree Finance is a barrier to implementing BIM ?
Do you agree Training is a barrier to implementing BIM ?
Do you agree Legal Issues are a barrier to implementing BIM ?
Do you believe BIM should be made mandatory for all construction projects ?
Interview Quotation from Participant No 1 The real issues with construction in Ireland, 3 things that need to be addressed: • Motivation – Improve financial support from the Irish government to push the benefits of using BIM. • Collaboration – the whole idea is to collaborate as a group. You need to use integrated contracts, better risk share, and employ contractors earlier on in the project. The whole way we do things is wrong. It’s not SMART. We are good at building not very good at doing bigger jobs. • Enable the supply chain to use BIM – train them properly. Same consistent training during training. Specific curriculums tailored to the specific group. Dr. Alan Hore, Founding Director CitA (2023)
Results:
The survey gathered data on respondents' work experience, company size and type, sectors worked in, perception of and use of BIM in construction. While BIM is viewed as relevant and frequently used, there may be differences in how it's perceived. Reasons for reluctance to use BIM include: high training costs, lack of experience, client demands. Respondents show high familiarity and expertise with BIM, but a potential skill gap may require training and education initiatives.
Conclusion:
In conclusion, this dissertation has contributed to the understanding of BIM implementation in SMEs in the Irish construction industry. It has highlighted the challenges faced by SMEs and identified strategies that can be employed to overcome these challenges. The author suggests the following to improve the implementation of BIM : Utilise government support Provide training Start small and scale up .Encourage a culture of innovation More involvement with stakeholders and supply chains Programme: BSc (Hons) Construction Project Management Module: Dissertation QUSU08023 Programme Chair: D.

Introduction.
Results:
Due to increasing urbanization and climate change, it is becoming more common for cities to experience flooding which occurs when surface water runoff overwhelms urban drainage systems. As much as 300 communities all over Ireland are at risk of flooding, unless significant investment is made in relief works. This research found that 90.5% of 21 people surveyed, were not affected by flooding in the past twelve months.
Qualitative Results. As part of the research, five people were interviewed, one person had been directly, severely affected by flooding, and four other participants were experienced Engineers dealing with flooding issues on a regular basis. The participants interviewed, reported a range of answers, including climate change with more frequent, and intense rainfall occurring annually.
This analysis shows that there is an increasing feeling among communities in Ireland for a more natural way of managing the risk of flooding. To lessen the water peaks that frequently cause flooding by delaying and accelerating water flow through a watershed.
Poor planning decisions in flood prone areas, which than increases the impermeable surfaces and surface water runoff. All of the interviewees said that the current existing drainage systems in place were inadequate with combined storm and sewer systems being a particular area of concern. ^ŽƵƌĐĞ͗ &ůŽŽĚŝŶŐ ŝŶ Ŷ hƌďĂŶ ŶǀŝƌŽŶŵĞŶƚ͘

Aims:
The aims of the research were to investigate the cause and effects of urban flooding, evaluate flood management techniques, add to existing knowledge, appraise the results and find the most effective sustainable methods of preventing urban flooding.
Methodology:
The research used a mixed methods methodology approach that combined both qualitative and quantitative methods to gather and analyse data. This approach provided a more comprehensive understanding of the research topic, as it allowed both subjective experiences and objective measurements.

The survey results showed that while 90.5% of participant's were not directly affected by flooding in the previous twelve months, 47.6% agreed that flooding events were becoming more frequent due to climate change, and whilst most people did not have previous knowledge of sustainable drainage, 71.4% of participants agreed that there should be more sustainable, nature based drainage systems used to prevent flooding.
In conclusion, the analysis of the quantitative and qualitative data on urban flooding highlights the urgent requirement for the introduction of sustainable measures to mitigate the impacts of floods in urban areas. The research found that Local government bodies in Ireland are not using Suds systems as frequently as required. Improved collaboration is required between the relevant state bodies. The Department for environment, Food & Rural affairs (DEFRA) Future Flood Prevention report, opened up a conversation on how best to achieve this .We need to reduce flood risk holistically if we want to convince society that flooding is everyone’s responsibility. As part of a comprehensive strategy, homeowners and businesses both have a part to play also, but changing how individuals and organizations act is necessary. Transparency is necessary so that individuals can understand their place in the flood risk management puzzle.

Justification of Research
Survey results by their position in the industry
The funding of Irish construction projects is crucial for promoting economic growth, identifying alternative funding sources, staying current with emerging trends, comprehending the impact of governmental policies, and developing best practices in project financing, as a conclusion to my justification for choosing this topic. The creation of best practices in project financing, which can reduce risks and enhance project outcomes, can benefit from research on financing construction projects. For instance, studies investigating the viability and dangers of using crowdfunding as a funding source for construction projects can shed light on these issues.
Purpose of the Research
To better understand the many financial options available to developers and investors in the construction sector, research is being done on construction funding. Research on construction financing can aid in locating additional sources of money, weighing the risks and rewards of various funding solutions, and revealing new patterns in project financing.
Findings
Recommendations
❖ Since the last economic downturn in 2008, securing financing for construction projects in Ireland has been a very challenging and rigorous process. The government has come under fire for failing to make funding available for crucial housing and infrastructure projects to keep up with Ireland's expanding population. ❖ Many case studies illustrate that money can be obtained, and they also demonstrate that Ireland is growing increasingly dependent on foreign direct investment. ❖ The results of the data collected from both quantitative and qualitative surveys showed that funding and investment are available in some financial institutions, but the days of pension funds and vulture funds are over. Today, the main sources of funding are international investments for residential real estate and European investments for infrastructure developments.
There are various recommendations available for financing construction projects. ❖ Government grants and loans: Several governments provide grants and loans for building projects that satisfy specific requirements. They could, for instance, be initiatives that support economic growth or provide employment ❖ Private investors may be interested in supporting building projects with the potential for substantial profits, such as venture capitalists or angel investors. ❖ Self-funding: If you have the means to do so, you might want to consider self-financing your construction project. This may entail borrowing from personal resources or using personal assets like a home or other real estate as collateral but it can be dangerous to self-fund.
Conclusion In conclusion, although financing construction projects might be challenging, investors and developers have many options. Alternatives to traditional bank loans for financing construction projects include crowdsourcing, government grants and loans, private investors, and self-funding. It is essential to keep an eye on emerging funding trends as the construction industry grows if you want to continue to be successful at obtaining financing for new projects. Funding Positive findings ✓ International investment is prominent in Ireland. ✓ European investments in infrastructure are improving. ✓ The rising costs of materials and labor hire haven’t affected progress. Funding Negative Findings ✓ Costs of material and labor have slowly scared off pension fund investors. ✓ Lack of knowledge of types of funding and how funding is secured. ✓ Difficulty in gaining experience in investments. ✓ Culture change, the government is slow to accept that investment is required in all areas.

Blockchain inhibits beneficial potential to overhaul and address continued problems in the construction industry
Blockchain can create a tamper-proof and secure record of every transaction and movement of goods along the supply chain, including financial transactions.
Blockchain based smart contracts, stakeholders in the construction industry can create a transparent and secure system for automating payment processes and ensuring compliance with contract terms. Once the employer approves the progress payment, the smart contract automatically transfers the progress payment amount to the digital wallets of the contractor, subcontractors, and supplier based on the agreed-upon terms.
Leveraging the existing standards and regulations established for BIM data management, the construction industry can accelerate the adoption and implementation of blockchain technology.

Student Email: S00196497@atu.ie
Supervisor name: Gary McGinty
I am a 4th year Construction Project Management student at ATU Sligo for my 4th year thesis I have decided to research Early Contractor Involvement (ECI) to determine whether it is beneficial to the design and construction processes of a construction project.
AIM The Aim of my thesis is to determine whether having the contractor involved early is beneficial to the design process and the construction process of a construction project
OBJECTIVES • To research Early Contractor Involvement as a procurement process, determine its advantages and disadvantages. • To compare and contrast Early Contractor Involvement to other procurement processes.
RATIONALE The author decided to undertake this
research as there were little to no papers published on the topic about the Irish industry and it is clear that there is not enough knowledge about the topic in the Irish industry. The author hopes to spread knowledge of the topic to those who are unaware and to broaden the knowledge of the industry
RESEARCH FINDINGS From the research conducted the author
It was found that ECI could greatly benefit the design and construction processes of a construction project as long as it is implemented correctly. It was also found that large contractors are the only ones using the method.
Widespread implementation of the technique throughout the country is essential to improving the industry and getting it to where it needs to be. Seminars and workshops for smaller contractors are needed to spread the knowledge of the technique and to help it grow
found.
• That traditional methods were too slow and archaic • That traditional methods tend to adverse and unsuccessful
• To research the relationship between the client and the contractor during the process.
• That traditional methods commonly led to time and cost over runs
• To analyse the procurement process from start to finish to determine its value.
• That traditional methods led to a lot of mistakes and rework on site
• To analyse the construction process to determine its value.
• That traditional methods often ended in dispute, claims and relationships on site breaking down
• To determine if Early Contractor Involvement is beneficial to the procurement and construction processes of a project.
• That ECI speeds up the design and construction processes
METHODOLOGY
• That ECI reduces mistakes and the need for rework
The author will be using a mixed methods approach to the thesis. The author will be using a combination of qualitative and quantitative research combined with a literature review and pilot study Literature Review Is where by information is gathered from previously published papers on the topic wrote by academics Qualitative Research This is where by information is gathered through semistructured, open ended interviews. The author conducted 6 interviews Quantitative Research Is where by information is gathered through questionnaires or surveys then analysed
CONCLUSIONS & RECOMMENDATIONS
• That ECI improved health and safety on site • That ECI promotes positive relationships and open communication on site • That ECI reduces time and cost and leaves the client overall more satisfied with the end product

Constructing Round.
A comparative study of rectilinear and curvilinear construction. Department of Civil Engineering & Construction School of Engineering and Design
Student name: Justin Hawthorne
Student ID:S00201304
S00201304@atu.ie
Supervisor name: Enda Mc Tiernan
Introduction
Methodology
The construction industry must now address issues surrounding material wastage, energy usage and its ability to address circular economy. The following spurned the research topic;
• An extensive literature review of academic articles, published papers and journals. • Qualitative Research in the form of three face to face, semi structured interviews with industry professionals • Quantitative Research in the form of a Likert scale survey (1 = strongly disagree; 5 = strongly agree) completed by 30 respondents
• Mathematically the circle has the shortest perimeter for a given area • For millenniums curvilinear form had been the only method of construction • The natural world utilises the circular form to maximise efficiencies and minimise wastage Would it not be logical to consider curvilinear structural form once again and by doing so the industry could improve upon the principles of lean and circular construction?
Aims & Objectives Research Aims
• To rationally without bias set out the pros and cons of curvilinear construction and to identify why this form has not become a common building method
Research Objectives
• To examine Curvilinear construction methods employed and reasons why it ceased in popularity. • To discuss the logic of nature and survivability and how this can be used to improve efficiency and durability of construction. • To explore the positives and negatives of curvilinear construction. • To compare and contrast material usage, strength of structure and energy efficiency of both curvilinear and rectilinear construction.
Results
Past
• Curvilinear design ceased in popularity as a result of increased agriculture, globalisation & iron tooling leading to modularised construction material such as sawn lumber & clay bricks • Circular form increases potential solar gain and natural ventilation • Neurological benefits associated with curvilinear design • Difficulty in obtaining skilled labour and material availability • Mitigation of external sound transmission in curvilinear forms • Increased strength of structure due to spread point loads • Reduced wind loadings by over 50% in ‘roundhouse’ design • 15 -20% reduction in materials when built faceted • Perceived difficulty in furnishing • Future adaptive building associated with full curvilinear design

Recommendation
Conclusions The results indicated that curvilinear design is a viable method of construction due to: • Increasing energy efficiency This is shown by improved air movement internally, less external wall area to floor and the ability to harness increased solar gain and natural ventilation passively • Improved whole life cost Although curvilinear form increases upfront costs data suggests that this is off set when considering a whole life approach • Material usage can be reduced by as much as 20% When adopting a modular faceted design particularly timber frame, materials can be reduced significantly compared to rectilinear design for a given floor area. • Strength of structure Improved stability during high winds without increased engineering costs, spreading of point loads reduces likely hood of structural failure
The research raised advantages that are clearly beneficial to construction and the occupants within a building and also those externally. Some key areas for future investigation are :
“The architect Charles Deaton summed up architectural form by asserting “If people do not have angles, then we should not live in boxes”.
• Continued research in to the neurological benefits of curvilinear design in construction • Conduct acoustic modelling of both circular and faceted design with open and segregated layouts • Perform thermodynamic modelling in both circular and faceted design to provide data for analysis of energy performance • Whole life cost analysis to include design, build & future operating costs of circular and faceted design • Potential of faceted circular construction here in Ireland using locally sourced timber

S00196751@atu.ie
Supervisor name: Gary McGinty
Introduction
Energy – its conservation and management plays a crucial role in today’s world, powering our homes, businesses and industries. As the demand for energy continues to rise, we are faced with the growing challenge of conserving, and managing the valuable resource sustainably. Commercial buildings and services accounted for 15.6% of Ireland’s energy consumption in 2021 (SEAI, 2022). The SEAI also noted that the commercial sector is one of the fastest growing energy consumers in Ireland, with a 32% increase in energy consumption from 2005 – 2019 (SEAI, 2020). This growth is primarily due to the expansion of the sector, and the increasing use of digital technologies in these buildings.
This research project focuses on exploring the energy usage, conservation and management practices of Irish commercial organizations. By investigating the factors that influence energy management decisions, the study will contribute to existing knowledge by identifying opportunities for improving energy efficiency, and reducing waste.
Results & Findings
The four interviews with industry experts provided a great insight into what practises they find work best, and what issues are present to commercial consumers of energy. Some of the data gathered from qualitative interviews includes:
▪ Regular measuring and monitoring of energy performance is crucial to reducing consumption and costs. ▪ Constant communication is essential to inspire energy-saving behaviour with stakeholders in an organization. ▪ All interviewees agreed that capital investment was a huge obstacle to the adaption of energy upgrades & retrofits. ▪ The interviewees agreed that Ireland is not optimizing the use of off-shore wind farms, especially along the West coast. From this, the questionnaire gathered further data on these areas. Some of the interesting answers are shown below: ▪ Only 13.6% of participating organizations are certified with ISO50001 – while 31.8% have never heard of the standard. Yes – our organization is certified with ISO50001 Yes – our organization are currently pursuing this standard
Aim & Objectives
Yes – but our organization has not met this standard
The primary aim of this research project is to explore energy and its management across Irish commercial organizations. ▪ To determine the history of energy management, and how it has evolved with modern technologies. ▪ To analyse Energy Management Systems (EnMS), their utilization and how effective they are. ▪ To explore energy retrofit projects, and identifying barriers to their implementation. ▪ To assess the awareness and satisfaction with the international standard ISO50001.
Methodology
Mixed methods of research have been utilized for this project:
No – I have never heard of ISO50001
▪ 90.9% of participants do not agree that the Irish government are doing their best to reduce our carbon footprint.
Discussion & Conclusion
After analysing the data gathered from the interviews and questionnaire responses, this research project has identified the best practices for commercial energy consumers, and also some of the barriers which are preventing the widespread adoption of energy upgrades –
▪ Measuring and monitoring of energy consumption is essential in order to make improvements. The use of a building management system (BMS) has been greatly appraised for this reason.
Literature Review
Qualitative
Quantitative
▪ Firstly, a review of existing literature such as articles, books and publishments was undertaken to gather secondary data from existing knowledge on the topic.
▪ Next, four semi-structured interviews were conducted with industry experts to gather primary qualitative data for my research objectives. ▪ Finally, an online survey questionnaire was created and shared with more industry professionals to gather primary quantitative data on commercial energy.
▪ Capital investment is a huge barrier to the implementation of energy retrofits. There is not enough recognition of return-on-investments. ▪ Renewable energy sources (RES) are becoming more popular – especially solar panels. However, Ireland are falling behind with offshore wind production, and this needs to be invested in going forward.

3.METHODOLOGY
4. DISCUSSION
A mixed-method approach was taken involving qualitative and quantitative research.
The research found that the role of the Project Manager has changed. The modern PM taking control of MMC and Modular led construction projects has a higher level of responsibility placed on them. Their role has become one where they are expected to manage the project, have input from an early stage with the design team, manage financial matters and value engineer systems.
Interviews were carried out to establish the duties of a Project Manager before the widespread adoption of MMC. By setting a baseline, the research could then set out to see how much the roles and responsibilities have changed, if at all. Quantitative research was carried out with the assistance of industry professionals and experienced Project Managers.
They are also tasked with motivating the team and forming and cultivating relationships with specialist vendors, manufacturing operatives and supply chain managers.(Dasi et Al – 2021) There are similarities in the research between the findings of the interview stage and the literature review. The traditional PM, who would walk the site every day and return progress reports from the foremen to the company, the PM who would “get on their tools” to make sure a project was completed are being moved on. This is not necessarily a bad thing though, as the new breed of highly skilled project managers can take responsibility and ensure projects are completed by using intelligent and well-thought-out strategies and site-processes. (Searson & Esposito – 2022)
5. RESULTS & FINDINGS The findings in the qualitative and quantitative research have a direct correlation in this research. The interviewees presented their opinions on the role of a traditional PM. This was a hands-on role managing daily tasks and working at the coalface to complete projects. The interviewees then elaborated on their ideas of what they expected to see and require from a PM on a large-scale project using MMC or Modular Construction. The responsibility of the modern PM, from the findings of this research appears to be less hands-on and will require more soft skills. The PM will need to develop relationships with supply chain managers and off-site manufacturing managers. This was supported by the quantitative research in which survey participants suggested that they would need skills such as patience and empathy, or public speaking and motivational training. The literature from more modern journals also aligned with these posited ideas. The research suggests that MMC led projects will present a new set of challenges for Project Managers that will need to be further educated and have higher responsibilities during the project lifecycle.

Analysing the Importance of Production versus Safety in Construction Relating to Company Profits Department of Civil Engineering & Construction School of Engineering and Design
Student name: VITALIE EREMIA
Student ID: S00220452
S00220452@atu.ie
Supervisor name: Donal Ryan
Justification for the research
Introduction
Analysing production and safety in construction, which are the most important procedures in the company’s profits, mistakes in those steps lead to one outcome the company loses money, which is why project managers must focus on increasing the efficiency of their projects. Improving productivity can have unforeseen impacts, such as a decline in safety, and consequences like an increase in accidents if too much attention is placed on it. The aim is to identify the weaknesses and strengths between productivity and safety in construction and identify the company's profits or losses.
Interview Results Results from Quantitative: Q24. Would you like to add any other ideas to this research? Answer: - Company insurance and personnel liability are the most important documentation for the construction industry. Risk must be quantified and dealt with care. - Covid definitely has impacted site delivery dates of materials. What would have usually taken approximately 4 weeks, ended up taking 810 weeks. Also, alternative plant, equipment, and materials had to be proposed for Design Team approval because previous products were no longer available.
Compare the performance of productivity and strategies of implementation. Highlight whether the characteristics of the client have a significant effect on project performance.
Comparing the survey completed and interviews conducted could be seen that Safety in construction is not the issue compared to company profits loss but may be the reason that production is slightly reduced due to the Risk of being injured trying to increase productivity.
Aims and Objectives
safety in construction projects and different
During the research process, analysing all kinds of issues related to Productivity Safety and Profits can be identified from Q6, 50-75% agree that all projects have an extended construction time also face to face interviews in Q27 prove that around 80% are the percentage rate to finishing the project on time. Qualitative question, 27. What percentage of completed projects were on time? The answer, A programmed rate of 80%.
Analise safety in construction and compare how productivity is affected.
Conclusions
Uncover whether the designer's changes affect project performance and how late changes affect productivity and safety.
Qualitative
Methodology
Mixed Method
1. Literature review
65 no academic journals were reviewed - Construction Management - Analysis of the MultiRelationships and Their Structures for Safety Culture - Ways to increase productivity is knowledge, for example, Training - Unexperienced Supervision - Planning - Resource Scheduling - Safety Behaviour Measurement and regulations - Highlight whether the characteristics of the client have a significant effect on project performance.
Quantitative
3. Online questionnaire
28 response
2. Semi-structured interviews
-
-
The questionnaire contains 24 questions, which have been composed of insufficient data analysis in order to gather actual information. In-person site interviews with Construction professionals were completed. Including Contracts Managers, Quantity Surveyor, Safety Officers, and Projects Managers.
24 No. Multiple-choice questions
Survey results proving also that the language barrier is a significant factor in safety and production, by simply viewing the chart, the section: agrees and strongly agrees can be seen: 77.7 % is a major issue. 3.7% Strongly Disagree 4.7 % Disagree 11.1% Neutral
Findings
Analysing each result could be seen that not only Site Safety Roles may impede productivity but Design Changes, Planning, and Poor Management. Late information is a big contributor to safety and production issues also, the weather is a major factor that leads to safety and profits attention. Personnel motivation is critical to all three factors: SITE SAFETY ROLES PRODUCTIVITY and PROFITS. Design Change Communication / Collaboration Poor Management Late Information Unforeseen weather change Personnel Motivation
Recommendations
51.9 % Strongly agreed that late information is a major issue for all three factors, and 37% Agree to the same issue meaning that overall we have 88.9 % of the Site’s issues are LATE INFO. Only 3.7% of the categories Strongly Disagree, Disagree, and Neutral.
In order to achieve a project that makes a profit and has zero accidents limited risk taken and increased productivity many factors contribute to all this happening we have to implement constant training for personnel to motivate, also, need to have a good understanding of Site Safety roles. Experienced managers and good Company safety behavior. Relation between managers and the working person needs to be both ways this way we can eliminate all the ambiguity in the Construction Industry.

Methodology Literature Review: The literature review serves as a foundation for both the quantitative and qualitative data collection and analysis, by providing a comprehensive overview of the existing knowledge and research on the topic. By using a mixed methods approach, a more complete and nuanced understanding of research topic can be attained. Mixed Methods The pursuit of a mixed methods research approach was adopted by using both quantitative and qualitative methods. The exploration of both methods was to allow the gathering of nuanced data that captures the complexity of the research aims and objectives. Qualitative: 4 Semi-Structured interviews with industry professionals form part of the qualitative research methods used in the study. Quantitative:
An online questionnaire forms part of the quantitative research methods used in the study. The questionnaire allows for the mix of industry related participants and the general public by allowing them to be categorized.
Conclusions Has Covid impacted the delivery of Housing? When Covid-19 restrictions were implemented, forcing construction sites to cease operations, it had a knock-on effect in relation to supply chain issues and workforce. • One housing developer claimed covid had no effect on the company's ability to deliver projects but forced them to look at their supply chain differently. • Another developer felt it had a huge impact, leaving them running at “half capacity” due to the entering and exiting of lockdowns. • The supply and price of materials was something that hindered 3/4 interviewees in delivering projects. With one Tier 1 contractor claiming “inflationary pressures (on materials) made some projects, particularly apartment developments, struggle in terms of viability Are current government policies insufficient? The research shows the only way to increase housing supply is to address the issues surrounding government policies. According to developers/contractors, recent policies like Croi Conaithe and Housing for All are doing a reasonable job, but issues around planning permissions are majorly hindering companies' abilities to deliver houses. “The planning system is not fit for purpose.” – Interview B With the demand for Housing set to grow over the coming years, resolving these issues is vital in order to tackle the affordability and availability of housing. 30% of the cost to build a house is taken by government through taxation. According to contractors and developers interviewed, addressing the VAT rate is something that can impact the affordability of Housing positively.

Abstract
This dissertation examines the possibility of modernising older buildings. The study has five goals: First, to analyse the policy context of retrofitting in Ireland; second, to investigate the most energy-efficient building materials used for retrofitting; third, to critically appraise renewable heating and lighting energy systems; fourth, to test airtightness in a build and how to achieve a better BER rating; and finally, to evaluate the affordability and long-term savings of retrofitting. This research uses documentary research, examining existing literature. This study shows that upgrading existing buildings improves end-user experience and brings older structures up to modern performance standards. Energy-efficient building materials and renewable energy technologies are becoming more popular in the construction sector. Airtightness in retrofitted buildings improves BER ratings and energy efficiency.
Methodology
Project aim
Study approach: Qualitive and quantitative through interviews and questionnaire.
This dissertation examines the technical, economical, and social problems of upgrading older buildings for energy efficiency and sustainability. The study will identify retrofitting project challenges and solutions to overcome them. The dissertation analyses successful retrofitting case studies and draws on several theoretical frameworks to provide policymakers, building owners, and other stakeholders with sustainable and energy-efficient construction advice.
Population sample: self build people, people working or studying in the construction area. Response: 66 responses on questionnaire. three interviews with Working professionals where their work is based on the topic.
Survey Results
Results showing if the survey participants are familiar with the governments grant scheme to restore old houses in Ireland
Results showing if the participants would or not take into account the passive house standard that results into ultra-low energy buildings with high levels of occupant comfort when building
Interview results From interviewing the relevant working professionals there were several tendencies that emerged with them during the interviews I conducted with them.
Results showing if the participants think using old building stock is a viable solution to the housing crisis in Ireland
Results showing if the participants would opt to renovating old building stock apposed to new builds.
First of all, they all agreed that one benefit of renovating existing stock is that you don’t need planning permission to renovate an existing building, planning could take years otherwise, clearly demonstrating savings in both money and time. They also remarked that the quality and durability of the materials used in older building stock can provide a sense of character and charm that is difficult to replicate with modern building materials.
Conclusion
In conclusion, retrofitting old building stock is a more sustainable, cost-effective, and responsible solution than building new. By upgrading and improving existing buildings, we can achieve the same performance levels as modern builds, while preserving cultural heritage and minimizing environmental impact. Retrofitting also offers a solution to the shortage of affordable housing in urban areas, as older buildings can be repurposed and refurbished to meet modern housing needs. Moreover, renovating older buildings does not always require planning permission, making the process quicker and more straightforward. In summary, retrofitting is a viable and practical approach to creating a more sustainable, liveable, and resilient built environment.

Wind Energy as a Green Alternative Department of Civil Engineering & Construction School of Engineering and Design
Student name: Brian Kelly
Student ID: S00179486
S00179486@atu.ie
Supervisor name: Paul Hamilton
Introduction
Results
The purpose of this dissertation was to investigate the use of sustainable energy production methods and to compare it against fossil fuel energy production.
The results obtained from the questionnaire show as follows Q - Renewable energy sources such as wind energy and solar power are essential.
Electricity is a vital component in our lives, with our dependency growing even further with the introduction of heat pumps in new homes and the removal of oil-burning heating systems. Electricity prices have been steadily rising, it is important to produce energy at low costs which will, in turn, reduce the consumer’s bill.
Q - Would you be willing to pay slightly higher energy bills to support the development of wind energy in Ireland?
Pictured below is Oweninny wind farm in County Mayo.
Q - Do you think the Irish government should invest more in wind energy?
Discussion of Results
Objectives The objectives of this dissertation were to : •
Explore alternative methods of energy production
•
Investigate wind energy as a primary source of energy production
•
Compare the current methods of energy production
•
Prove or disprove that wind energy is in fact a green alternative capable of meeting the ever-growing energy demands of Ireland.
Methodology
A mixed methodology approach has been used for the purpose of this dissertation. Interviews have been completed with industry professionals in the energy sector. Fifty questionnaires have been completed using a sample from the general population. This sample was made up of individuals with varying levels of education and various professions. Using this sample population allowed the researcher to gain an insight into the viewpoints of the general population as energy production affects us all.
Graph 1 shows that 98% of participants believe that renewable energy methods are essential as fossil fuel production methods are not renewable Graph 2 depicts that 68% of participants are not willing to pay higher energy bills to facilitate the construction of more wind farms with a further 16% unsure. Graph 3 indicates that the participants believe more investment is required by the government in the wind energy sector. 89.8% agreed. Each interviewee was hopeful for the future of sustainable energy practices but firmly believed massive investment is needed to reach the targets set by the government.
Conclusion and Recommendations
Major investment is needed in wind farms to produce energy at a large scale to keep up with the ever-increasing demand of Ireland. Government organisations need to be more efficient in granting planning permission for wind farms which currently is the longest part of the process. The construction of offshore wind farms is recommended as there will be fewer planning permission implications and Ireland has a massive footprint offshore.

Introduction
Discussion
Many countries, including Ireland, have prioritized the transition to renewable energy sources Because the government of Ireland committed to the Paris agreement to reduce greenhouse gases and the use of fossil fuels. This is important because when fossil fuels are burned, significant volumes of carbon dioxide, a greenhouse gas, are released into the Department of Civil & Construction atmosphere. Fossil fuels Engineering are generated by the breakdown of buried carbon-based creaturesof that died millions of years ago. They produce carbon-rich deposits, which are School Engineering and Design mined and burnt for energy. They are non-renewable and now supply around 80% of the world's energy. They are also used to create plastic, steel, and a variety of other items. Coal, oil and gas are the three forms of fossil fuel. (Client Earth Communications, 2022). Greenhouse gases trap heat in our atmosphere, which contributes to global warming. Already, the average global temperature has risen by 1 degree Celsius. Warming exceeding 1.5°C threatens additional sea-level rise, extreme weather, biodiversity loss, and species extinction, as well as worsening health and poverty for millions of people throughout the world. This is important because we produced electricity by burning fossil fuel so in the interest of our people and future we must change our approach to generate power. In recent years Ireland has made significant progress in promoting renewable energy including the adoption of the 2030 climate action plan which set a target of achieving 70% renewable electricity by 2030.
Other energy sources, such as solar, are acknowledged to play a significant part in the future decarbonised energy mix. Solar technology deployment in Ireland is aimed at diversifying the country's renewable power mix during a 10-year period between 2020 and 2030, with a special emphasis on cost efficiency and efficacy. (Energy Ireland landscape white 2022 landscape, 2019) Currently Irelands renewable energy produces roughly 40% of our energy, but our reliance on fossil fuels needs to be dealt with as we all know this is not a sustainable practice. With more investment in renewable energy, we can and will hit 100%. During a recent visit to Ireland, European Commission President Ursula von der Leyen stated that the country is on its way to becoming an EU clean energy superpower. Currently Irelands renewable energy produces roughly 40% of our energy, but our reliance on fossil fuels needs to be dealt with as we all know this is not a sustainable practice. With more investment in renewable energy we can and will hit 100%.
Aims / Objectives
Greener planet
Wind and wave energy are two of the most promising renewable energy sources due to the country's location on the Atlantic Ocean. Wind energy is already a wellestablished source of renewable energy in Ireland, with wind turbines accounting for 36.4% of Ireland's electricity generation in 2020. 1. Research the factors surrounding the increased in demand on renewable energy systems. 2. Evaluate the current state of Ireland 3 primary renewables plus the potential for growth.
.
3. Environmental impact on renewable energy sources on ecosystems greenhouses gas emissions, impact on marine wildlife. 4. The effectiveness of wind and wave energy, as well as solar panels, in meeting Ireland's renewable energy targets. 5. What is the driving force behind the price of electricity. .
Conclusion Department of Civil Engineering Results & Construction School of Engineering and Design
The discovery makes several points; There is still a lot of work to be done in order to meet the Paris agreement's target of reducing greenhouse gas emissions. The main point is that the planning phase for wind and solar farms takes far too long through Bord Pleanála. The connection to the main power grid requires improvement.
73% have no renewables
Tidal wind farms require significant funding to be established, and ports for vessels to work on these deep-water wind farms must be further developed. Many are still underdeveloped. The price of gas it tied to the price of electricity.

Analyses
Introduction The most basic way to indicate whether a country has an adequate amount of housing is access. The issue of access is often closely related to the issue of affordability.
❖ Housing for All lays out the governments plan to increase housing supply to roughly 33,000 per year by 2030. Based off the housing starts statistics, the Irish government was unable to meet the yearly target in 2022
The Government of Ontario established a Task Force to develop a report called Ontario Housing Affordability Task Force report. The 2022 report sets out ambitious goals and recommendations for new housing developments across Ontario to combat the crisis at hand.
Conditions Exacerbating the Crisis in Ireland ❖ There are many conditions that are contributing to the affordable housing crisis in Ireland: Material cost increase, supply chain shortages, labour shortages and costs, utility cost increase, COVID-19, Brexit, and the conflicts between Russia and the Ukraine, immigration increase
The Irish government has a comparable report called the Housing for All scheme that was released in 2021. The scheme lays out guidelines that will be followed to lift Ireland out of the current housing markets state and carry it into a new age of affordability and availability. Although the scheme has been implemented in Ireland and the recommendations have been reviewed and some have been accepted in Ontario, there are still issues that have been highlighted within each locations government that need to be evaluated, including their housing policies, challenges of scheme implementation at local levels, red tape and bureaucracy.
Research Aims and Objectives The aim of this dissertation is to research and understand the true affects the housing crisis has had on Ireland and Ontario. To explore the affordable housing schemes created by each government and see what is being done to mitigate the situation while comparing the two schemes to one another. The goal is to understand Ireland and Ontario’s implementation of their schemes and see where any challenges may lye. 1. Develop a greater understanding of the Ontario Housing Affordability Task Force Report and Irelands Housing for All Scheme. 2. Evaluate the many factors contributing to why both Ireland and Ontario are struggling to supply a sufficient number of homes in reasonable time. 3. Perform a comparative analysis of the two affordable housing schemes to develop an understanding of why each government has created these schemes and identify the factors of how they are proceeding with it in finding the similarities and differences between both. 4. Develop an understanding of local and municipal involvement in the schemes. 5. Identify the challenges and red tape around the implementation of the scheme and recommendations.
Methodology
Both qualitative and quantitative research methods are necessary for this thesis. Mixed methods research resides in the idea that all methods have a bias and a weakness, and that the collection from both forms of data can neutralize the weaknesses.
Literature Review - Information collected by utilizing information from government documents, journals, articles, and other academic sources
Qualitative Research
Quantitative Research
- Collected through 5 - Collected through a questionnaire, semi-structured consisting of 30 interviews with questions, sent out to relevant industry a semi-controlled officials sample of relevant participants
❖ Housing for All has created pillars to follow that will aid the Irish government in increasing housing supply, provide affordability homes, provide land for development, delivery programs for local authorities, funding programs, incentives, and innovative methods of development ❖ The objective of the Task Force is to construct 1.5 million homes in ten years, which would roughly be 150,000 homes a year. Based off the housing starts statistics, Ontario was unable to meet the yearly target in 2022 Conditions Exacerbating the Crisis in Ontario ❖ There are many conditions that are contributing to the affordable housing crisis in Ireland: Material cost increase, supply chain shortages, labour shortages and costs, COVID-19, interest and mortgage rate increase, immigration increase, approval processes ❖ The affordability Task Force has created 55 recommendations that can be utilized by the Ontario government to increase housing supply, provide affordable home prices, reduce development fees, provide land for development, adjust zoning by-laws, and cutting red tape to build faster
Qualitative and Quantitative Results ❖ The specific processes of implementation and approval of the Ontario report and the Irish scheme ❖ Challenges faced during the implementation of the schemes and recommendations ❖ The municipal and local authority involvement in the schemes ❖ Red tape and bureaucracy found in government policy and administration ❖ Challenges the governments face while dealing with an ever-changing issue like affordable housing ❖ Governments plans for future growth and monitoring success ❖ Participants suggestions for growth and development in the affordable housing crisis ❖ “It was like a cross section of a rock formation, that, you know, government after government just adds another layer initiatives without ever changing the structure. And therefore, the problems remain the same.” – Eoin O Broin
Recommendations ❖ The Irish government needs to ensure that all counties are seeing the same favourable outcome of the provisions in places to ensure that Ireland can continue moving in the right direction of success and growth in its housing industry. ❖ Recommendations for the Irish government to remove the barriers placed around the local authorities to see better housing delivery results and creating the right investment levels ❖ To ensure that the Ontario government enacts the necessary legislative changes around the land and development fees to incentives developers to start building and reaching the 1.5 million homes target

Introduction
Analysis
Major environmental issues, including global warming, ozone depletion, and habitat destruction, have become increasingly prevalent in recent years. These issues are largely attributable to human activity. The average surface temperature has risen by 1.06 °Celsius from the preindustrial era. The building industry alone is responsible for 36% of all greenhouse gases (GHG) emissions and 40% of total energy use. Due to these changes, efforts are being made to find various strategies to combat climate change, including the decarbonisation CAP21 roadmap. ➢ 2030 – Retrofit 500,000 Dwellings to a B2 BER Standard ➢ 2050 – Net-Zero GHG Emissions Some of the Domestic Renewable Energy Systems discussed were: • Heat Pump Heating Systems • Mechanical Heat Recovery Ventilation (MHRV) • Solar Photovoltaic (PV)
During the literature review, various types of primary energy sources to produce electricity were discussed. For Ireland to achieve its net-zero carbon emission targets by 2050, fossil fuels will need to be completely phased out, and more sustainable energy sources will be required. Q.14 shows 52.5% of respondents believe offshore wind should be the main source of renewable energy. 17.5% view wave and tidal should be focused on whilst, 15% think that nuclear energy is the best option. The respondents views were also shared by interviewee 1,3 and 5 who think that wind energy is underutilised.
Results
Aims & Objectives The research aims to look into the in-depth contribution of renewable energy and understand its contribution in line with the Climate Action Plan (CAP 21) 2030 and 2050 Residential targets. ➢ To look for and extract information on the progress of renewable energy versus fossil fuel-based energy. ➢ To analyse the contribution of renewable energy to decarbonisation. ➢ To analyse the importance and position of renewable energy in the present and for the future. ➢ To investigate the actual cost of renewable energy for homesteads and their sustainability in Ireland. ➢ To investigate the efficiency and carbon-free contribution of renewable energy versus fossil fuelled systems.

`
28 No. Survey questions in total were asked to all participants.
Step 2. Qualitative Analysis ➢ Five Semi–structured interviews were conducted with five industry professionals. ➢ Five research questions were discussed with all interviewees. ➢ Cognitive mapping was created for each interview.
Conclusions Based on the Qualitative interview responses and the Quantitative online questionnaire, this research examined the benefits of renewable systems decarbonising the Irish residential market in line with the CAP 21 2030 and 2050 targets. Results from the research show that renewable systems need to be enforced to combat the need for fossil fuels to fuel the heating demands of households within Ireland. In extension, the carbon emissions in Ireland need to be net zero by 2050. For Ireland to successfully transition into renewable energy systems and reach the 2050 carbon-free emission targets, the following key points were identified: ➢ Education on Renewable Systems – Householders, Developers, and Contractors ➢ Smart metering – Incentive householders to best manage their electricity consumption ➢ Retrofit Grants – Needs to be revised and grant process streamlined to incentive renewable use ➢ Renewables infrastructure – Harnessing more wind energy, wave and tidal ➢ Utility companies – Reduction on fossil fuels, and reduction on price on electricity tariffs ➢ More R&D into more renewable sources i.e. hydrogen, nuclear, to reduce GWP refrigerant gases

One of them specialised in house building while the other company focused more on the commercial side of the construction industry
In this research paper we will be researching in to modern methods of construction and finding out, how they affect the construction industry from sustainability to time constraints on site, and if they can help the construction industry
The participants were given 10 days to complete and 17 responses came back.
• We will look at what stage Modern methods of construction is at bot in Ireland, UK and mainland Europe and where its heading.
Findings
The purpose of this research findings chapter is to present the results of a survey conducted among 17 participants. The survey aimed to gather data and insights about a Modern Methods of Construction. 10 questions were answered. Questions were asked to get to know who was participating in the survey and to get there opinions on modern methods of construction. These questions provide vital feedback for the research paper.
Conclusion and Recommendations
Building houses faster more efficiently, while also taking the risk of construction sites and doing much more of the work in a safer factory environment. We can also see from the research that constructing parts of the building off-site can be much more sustainable as there is less wastage in a factory environment. Modern Methods of Construction represent a significant departure from traditional methods of construction. We can see from our research that it has the potential to change the construction for the better from faster construction times to more sustainable construction practices and more streamlined builds.

S00228446
Introduction
The issue of housing is ever present in Irish society today with the construction industry struggling to keep up with the demand. Traditional methods have proven to be reliable and cost effective in the past but current economic trends have had negative impacts on the market. Issues with procurement and access to labour have seen alternative construction methods being implemented. This piece will endeavour to show how modular construction can offer a viable alternative to traditional brick built homes in a market where money, time and access to resources are critical.
Aims
• To analyse the speed of delivery of modular homes against the traditional brick-built house • To evaluate the commercial impact of choosing modular. How do the capital costs stack up against that of a conventional blockwork house • To analyse any standout areas that impact the overall cost of modular projects. • To investigate whether Ireland has the resources available to deliver modular housing on a large scale.
Methodology
Literature Review • Multiple forms of material that were relevant to modular construction were assessed with the common themes noted and gaps commented upon. The results of the literature review were significant in influencing the direction of the overall area of study and it provided important questions for the tasks that followed. Interviews 1. Civil estimator with previous experience in modular construction and knowledge of the different models on the market. 2. Project quantity surveyor with recent hands-on experience of the benefits and pit-falls of using modular in a multi-unit development. 3. Sales director with an Irish based modular housing company. They gave an account of their company's role in the industry and how they viewed the potential opportunities for modular housing in Ireland. Case Study • This involved analysing the design and build of 2 separate 3-bed houses, one modular and the other brick built. Both projects were recently completed in rural Ireland. Each phase of either build was reviewed, and comparisons made, including the design, procurement, and construction. Each element of the works was scrutinised with particular attention given to the project duration and the cost.
Results
Time Impact • • The literature review returned consistent results of a faster completion time for modular house construction of between 20-50% when compared to brick built. • Each interviewee agreed that the main benefit of modular would be a quicker construction period. Less onsite activity with much of the scope being completed off-site in a factory environment, away from the elements. • The case study, where two houses of similar configurations were compared, showed a time saving of 40% for that of the modular build.

Commercial Impact • The literature review showed financial savings of up to 50% when choosing modular. The whole life costs also showed significant reduction compared to that of a traditional brick-built house.
Resources • The shortage of skilled labour and those working in the wet trades (brick layers, plasterers) has had a negative impact on Irelands construction industry. • Modular construction can mitigate shortages in skilled labour by moving construction to factory environments and implementing controlled, efficient work processes. • Diligent procurement can also assist to offset the current resource issues facing the industry.
Conclusion
• • • •
Commercially, the results showed that modular construction costs are higher per m2. For the programme, modular construction was shown to be a quicker alternative to brick built. The interview stage concluded that for the Irish construction industry to grow, it must embrace modular construction. The case study carried out was of huge benefit to this piece, there is potential for more comprehensive findings should a study be carried out comparing a bigger development in each case. This, as opposed to a one-off house development, may produce more comprehensive results.

An Analysis of the effect legislation has on ethics in Construction David O’Connor
Mairead Lynham
S00199887@atu.ie
S00199887
Introduction
Aims
The construction industry is well known to be prone to corruption and unethical behaviour with governments and professional bodies within the industry seeking to regulate it. there is a lack of research on the area to investigate the most efficient method of legislating ethics. The main aim of this dissertation will be to analyse how ethics is legislated in the UK and Irish construction industry and to determine if more legislation is needed to effectively legislate t. It is reported that the value of losses due to corruption is between 10-30%
Methodology
This research aims to examine the following
Following the Literature review, two interviews were carried out with professionals actively working in the construction industry. The questions were asked with the aim of finding the common opinion in the industry of topical areas relating to ethics.
• To establish the background, a discussion on why ethics is important in the construction industry.
Consideration was taken into account of the differences between the two interviewees background in the industry as one of the interviewees worked for a consultancy in Ireland and the other worked for a tier 1 main contractor in the UK
• To investigate the effectiveness of current legislation on ethics in the UK and Ireland • To investigate what steps can be taken to further improve ethics in the industry.
Findings Theme Organisational ethical policy
Quotation ‘We don’t tend to do any external courses. we predominantly follow SCSI code of behaviour’. ‘Yes, we have a bribery and corruption policy and mandatory online classes for bribery and corruption’.
Liability for employee’s ethical behaviour inside an organisation
‘I don’t think so I think maybe for a multinational, but we are a small enterprise we expect an ethical standard that all employees should follow’. ‘No, it is up to everyone’s individual obligation to ensure that they act in accordance with any company’s policy’.
Conclusion Verdict certain companies have a strict bribery and corruption policy while others follow SCSI/RICS code of behaviour.
The common view is that organisations should not take liability for their employees’ ethical behaviour
‘I’d say predominantly preconstruction.’ Stage of construction most ‘I think all areas are of it are such as at risk of unethical preconstruction’ practises
Preconstruction and all stages of the construction process are viewed most at risk of unethical practises
Introduction of new legislation
The opinion of introducing new legislation is not consistent
‘I don’t think so maybe in the wider construction industry, but I think it will be very difficult to implement’.
•
Legislation relating to organizational ethical policy can be described as effective
•
More legislation is required in preconstruction specifically preferential treatment in appointing contractors/sub-contractors
•
Gifts and hospitality is an area which needs more legislation.
•
Introducing more standards in procurement would assist in improving ethics
‘Possibly I’m not sure what or how but I think there should be legislation’

The Evolution of Preconstruction Estimation A Study of the Evolution of Preconstruction in Response to Digitisation
INTRODUCTION
Construction has historically been seen as slow to adapt to new technologies, however, as the sector continues to work toward BIM maturity, digitisation has led to significant changes in how in the AEC sector approaches the contemporary built environment, with many organisations making considerable efforts to adopt modern digital construction technologies and BIM aligned principles, systems, standards and infrastructure. In order to remain competitive in the face of higher demands from clients and increased levels of competition, preconstruction, has seen significant exposure to the changes brought by digitisation, adopting new methods and approaches made possible through the use of new and emerging digital construction technologies. With automated take-off and estimation software applications offering unprecedented levels of productivity and efficiencies, preconstruction estimation disciplines have evolved significantly in recent decades, with most traditional methods and approaches now in decline, being replaced with more efficient digital alternatives. As these digital construction technologies have evolved to meet the needs of Estimators and Quantity Surveyors, so too have the roles, responsibilities and skillsets of these professionals and this dissertation looks to show that preconstruction estimation, its methods and approaches, and the roles within it, have evolved with the digital tools and methods now commonplace in preconstruction.

METHODOLOGY
Qualitative research was used for this dissertation, with research data gathered from preconstruction estimation professionals through topical surveys and interviews, which offered the author an insight into whether respondents believed their roles had changed over recent years, to what extent, and whether they viewed these changes as positive, negative, or otherwise.
Interviews with Preconstruction Professionals Both informal, and partially structured interviews were carried out by the author, among preconstruction professionals like Estimators, Quantity Surveyors and other related roles and disciplines. The focus was placed on professionals active in cost estimation roles and those using BIM or BIM related tools and systems, and other commonly used digital construction technologies developed specifically for use in preconstruction estimation. Survey of AEC Professionals A detailed survey was conducted among a broad range AEC professionals working for larger and smaller organisations. This survey helped to establish the wider knowledge and awareness of evolving digital technologies and BIM and its principles, while also ascertaining if respondents believed digitisation has changed the way they approach their job.
RESULTS
This research shows that the evolution of the approaches, tools and methods used in preconstruction estimation has been a direct result of digitisation in the methods and approaches common to these roles. In the survey conducted, almost 75% of respondents noted that they used digital construction tools and software either daily, or most days, showing a clear reliance on digital construction technologies. The interviews conducted, also supported the survey results with most interviewees and survey respondents agreeing that the core skillsets in their role or discipline had changed in the last 20 years. In the survey carried out, only 11.5% of respondents said that very little had changed. The case study of one well established AEC sector organisation however, gave the clearest indication of these changes, with contemporary digital construction technologies developed for estimation being the preferred tools and methods for almost all steps in the tender processes used in this example.
Case Study: An Example of Digitisation in Contemporary Tendering Approaches By analysing how one leading organisation within Ireland’s AEC sector approaches cost estimation in a competitive tendering environment, the author provided an example how cost estimation is approached in a contemporary setting. This case study provided a worked example of how this organisation approaches cost estimation for tendering, giving a detailed insight into the digital tools and methods used during a competitive tendering process, indicating a clear shift in the construction estimation process.
AIM
The aim of this research was to show that evolving digital technologies have impacted on preconstruction estimation, by considering the approaches, tools and systems commonly used in preconstruction roles and by looking at the expanding digital skillsets now needed by preconstruction estimation professionals
OBJECTIVES
The objectives set out by the author before beginning the research were:
CONCLUSIONS
• The main findings of the research carried out was that the use of digital construction technologies in preconstruction estimation was widespread, with significant levels of dependence on digital technologies in contemporary preconstruction estimation observed. • The research also found that the implementation of digital construction technologies and BIM principles, systems and infrastructure, was widespread across the built environment sector, and the historic view of a sector slow to adapt to change was disproved repeatedly, with adoption and usage of digital construction technologies and automated systems and approaches now widespread across the sector and continuing to increase. • Although progress was markedly less visible among smaller organisations, the research indicated that this was not out of hesitancy or a lack of effort in these parts of the sector, but was more due to a lack of necessity, with many smaller companies commonly reporting that the costs and disruptions associated with implementing new digital systems and tools, were usually greater than the reward. However, the research appeared to show that as larger organisations adopt digitisation and BIM principles, smaller organisations are likely to follow suit as these technologies become cheaper and more accessible. • Interviewees and survey respondents undoubtedly feel that digital technologies are hugely beneficial to their roles as they offer new efficiencies and levels of productivity that were simply not possible in previous decades, when traditional paper-based and manual methods were more common. • The need to carry out time consuming and cumbersome tasks has significantly decreased, making the cost estimation process much less time-consuming and streamlined. • Survey responses indicated that the roles and disciplines within preconstruction have seen axiomatic changes, as contemporary professionals now need to have the digital know-how to navigate a multitude of digital technologies in today’s preconstruction estimation process.

Price Increases in the Construction Sector their effect on Tenders and Project Outcomes David Walsh
Supervisor - Pat Carter
s00201834@atu.ie
S00201834
INTRODUCTION
FINDINGS
In recent times there has been a significant increase in the cost of construction materials. The construction industry in Ireland encountered a scarcity of essential building materials and subsequent price hikes, as a result of the prolonged impact of the COVID-19 pandemic, following nationwide lockdowns. Subsequently there has been a volatility in market prices within the industry, which can be attributed mainly to the widespread inflationary trends stemming from the ongoing conflict in the East. Due to the volatility of material prices, suppliers are hesitant to maintain material quotations for long periods. This research carried out a comprehensive analysis of the literature pertaining to the impact of COVID, the War in the East, Brexit, and other relevant factors on inflation in the industry. The study examined the influence of these factors on project costs and outcomes, as well as the options available to contractors for managing these increases and the resulting effects.
AIM OF THE STUDY •
To establish the main issues that has caused the market volatility over the last 3 years.
•
To establish how these issues have affected projects being carried out and the outcome of projects.
•
To determine if the Ex-Gratia Payment Schemes are sufficient to cover the additional costs to the contractor.
•
To establish how tenders in the sector have been affected and how this in turn effects cost certainty of projects.
The survey recipients were asked to rate the impact of Covid, Brexit and the War in Ukraine on their projects. Surprisingly, most said Covid had a low impact whereas the majority stated the war in Ukraine has had the highest impact. Covid Ukraine Brexit No Impact 3% 3% 13% Low Impact 58% 0% 58% High Impact 39% 97% 29% Budget issues, supply chain issues, and the inability to procure materials and labour are among the most prominent issues cited by respondents. 63% of respondents cited difficulties in keeping projects within budget as one of the most significant problems caused by market volatility in recent years. Below are the main issues stated by the respondents.
90% of respondents said the quantity of delay claims and price variation claims have increased in their projects due to Covid/War and Brexit. Only 10% of respondents disagreed, saying these claims have not had a greater impact on their projects. Below is the average value of claims respondents stated have been submitted per project over the last 2-3 years as a result of the impacts of Covid, Ukraine and Brexit.
METHODOLOGY Building on the findings of the Literature Review, this study employed a mixed-methods approach for data collection. Initially, two interviews were conducted with individuals currently employed in the industry and who have been involved in projects impacted by price inflation within the past 23 years. One of the participants is employed in Northern Ireland, while the other participant is employed in the Republic of Ireland. This facilitated the comparison of the impact of the price increases on projects on either side of the border. The interviews were conducted using a semi-structured format. The second approach entailed the acquisition of statistical information through the use of a questionnaire. The survey was circulated among several individuals employed in the construction sector and received a 78% response rate.
42% responded as not being successful with any delay or price variation claim submitted whilst 39% were only successful in Private Works. Only 13% of responses were successful in claims under Public Works Contracts.
Conclusion • • •
Budgetary issues due to supply chain and procurement difficulties are one of the main issues facing Contractors as a result of the recent price hikes Contractors are forced to claim costs back and having little success which is causing prolonged disputes and a deterioration amongst project team relationships. Tenders continue to rise with Contractors forced to price for increased risk due to the uncertainty in the market. This instability is having an influence on the level of cost predictability for clients.

Aims • To research the different types of sustainability that may be used in building and how well they work to create energy-efficient homes. • To examine the advantages of utilizing eco- friendly materials in modern homes and how this can result in long-term savings. • To investigate how sustainable development affects the price and quality of residential building construction. • To assess the possibilities for Project Ireland 2040's objective to give greener homes preference in new residential construction.
Conclusion
Methods Literature review • A comprehensive review of the literature was carried out. This review is based on the existing published research that is relevant. • The purpose of this literature review is to investigate the value of sustainability in the construction sector, particularly about residential buildings, and how this impacts construction costs and quality. Survey • Using the data collected from the literature review, a survey with 10 questions was developed. • This questionnaire was responded by 10 professionals within the construction industry.
Results
•
•
The literature review shows that sustainable practices need to be improved in Ireland, initiatives such as Project Ireland 2040 are vital in promoting sustainable construction techniques and investing in green housing. The survey results show that one of the biggest drawbacks of homeowners implementing sustainable construction methods is the higher initial costs, this drawback can be minimised by introducing more funding and grants to increase the demand from clients.

INTRODUCTION
AIMS & OBJECTIVES
Transport in New Zealand is responsible for 17% of the country’s gross greenhouse gas emissions with two-thirds of transport emissions coming from light vehicles.
The aim of this of research is to study the barriers noted above in greater detail to identify the root causes and factors influencing the deployment of public Electric Vehicle Charging Infrastructure in New Zealand:
•
The Government has set a near term target of increasing zero-emissions vehicles to 30% of the light fleet by 2035.
1.
•
There is a direct relationship between the adoption of Electric Vehicles (EVs) and the perception of charging infrastructure availability
To understand the barriers to obtaining new connections to the electricity network for public Electric Vehicle Supply Equipment (EVSE) and the effects this has on deployment
2.
To analyze the profitability and return on investment for CPOs
•
Deploying a public EV charging infrastructure at pace and scale is fundamental to increasing EV uptake however several barriers to deployment have been identified by the Ministry of Transport: 1. 2. 3. 4. 5.
Grid Compatibility (Electricity supply factors) Profitability of Charge Point Owners (CPO) Project time Lack of coordinated national strategy Interoperability of Payment
3.
To examine the length of time required to deliver a public charging project and identify common factors affecting the programme
4.
To examine the need for a coordinated national strategy
5. To discover what obstacles stand in the way of payment interoperability
By researching and discussing the constraints and challenges in greater detail, can we identify opportunities to enable faster more efficient charger deployment?
METHODS The study reviewed available documents and white papers about electrification of transport and industry in New Zealand. Information was gathered from government reports, published standards, legislation, regulation, codes of practice and other relevant sources. An overarching study of the electricity distribution network was prepared alongside real-world case studies using historic new connection requests to examine the barriers to accessing the network. This required a significant amount of context setting to describe New Zealand’s decentralized, privately owned distribution network. Survey participants were also questioned on the matter to understand their experiences and opinions. Historical data from completed projects was aggregated and valued to determine average costs to deploy chargers of different types. This was considered against the cost of charging as publicly advertised by CPOs operating in the country and modelled to determine length of time to realize a return on investment and provide context to the literature and survey responses relating to profitability. Finished projects, available to the author, were reviewed to identify the median completion time. Outliers were studied in further detail to determine their relevance to the discussion. Survey respondents were queried on their experience and satisfaction with project timelines. A literature review was undertaken to identify the need for a coordinated national strategy and interoperability of payment. A questionnaire was also used to further gauge industry participants opinions and thoughts regarding their importance.
FINDINGS NEW CONNECTIONS identified by survey respondents as the biggest challenge:
Literature review findings: • • • • • • • • •
New Zealand had 29 Electricity Distribution Businesses (EDBs) EDBs are regulated by the Commerce Commission and Electricity Authority as natural monopolies Regulation includes revenue caps. Expenditure must be forecast for the regulatory period of 5 years Forecast must include system growth expectation Each EDB sets their own capital contribution policy for new connections resulting in pricing variability Each policy is reflective of an EDBs attitude to risk of under recovery of costs through their forecast There are no unifying new connection processes or handling timeframes EDB asset location (GIS) and capacity information is not publicly available These factors are seen as highly significant impediments to Charge Point Operators (CPOs) looking to build sites
The average TIME TO DELIVER A PROJECT, as calculated using empirical data available to the author is is equal or better than that estimated by survey respondents. Satisfaction levels with the length of time to deliver are split evenly between somewhat satisfied and somewhat dissatisfied. The consensus among respondents is that the new connection process is the biggest factor in causing project delays. There was limited literature available to support these findings. Time to deliver

Calls for a NATIONAL EV CHARGING STRATEGY were widespread throughout the literature with the sentiment strongly supported by survey respondents. “It is critical that government departments and agencies like MBIE, MOT, NZTA, the Commerce Commission, and the Electricity Authority work together to facilitate the development of an efficient, reliable, and competitive market for electric vehicle charging.” (Energy Efficiency and Conservation Authority, 2021, p. 97).

There was widespread support for INTEROPERABILITY OF PAYMENT with most survey respondents believing it essential or very important to continued uptake of EVs. This is supported by the literature (mainly referencing more mature markets). There was agreement that implementation would be somewhat difficult but not impossible. Estimates on the time required to implement varied, however, the majority believed it could be implemented within 9 months to 2 years. There was some support for a government mandate to drive implementation with only one respondent against the idea.

Literature review and data sets available to the author support claims that CPOs are yet to be become PROFITABLE References in literature limited to anecdotes stating CPOs unprofitable Attitudinal survey respondents agree with the sentiment however and is supported by data analysis
To test profitability, aggregated cost data available to the author was used to determine an average cost to deliver AC and DC sites with a supply capacity under 100A. This was measured against average utilization of existing assets and an average cost to charge from various CPO’s advertised rates to determine the length of time at current utilization levels it would take for a site to recover costs.

S00198970@atu.ie
S00198970
Introduction Ireland experienced an economic boom known as the Celtic Tiger from the latter half of the 20th century to the beginning of the 21st century, driven by the construction industry. However, the rapid production of homes during this period led to issues with energy inefficiency and heat loss. This, combined with a cost-of-living crisis and rising energy costs, has negatively impacted users' thermal comfort and energy bills. Passive housing has been considered as a potential solution to address these challenges by providing sustainable housing, reducing CO2 emissions, and mitigating rising energy costs.
Aims • • • • •
Explore the principles of Passivhaus construction Assess PH cost-effectiveness Suitability to the Irish Climate. What are the barriers and challenges of the PH standard ? Analyse the effectiveness of current building regulations and climate action plans in meeting NZEB targets. • Evaluate the level of knowledge regarding the PH Standard among professionals and homeowners.
What is Passive Housing? • Passive construction prioritizes energy efficiency and sustainability. • Passive building standards establish specific requirements for building design, construction, and operation. • Goal of passive building is to limit energy consumption and reduce environmental impact. • Passive Houses eliminate the need for traditional heating systems for low heating costs and high comfort. • Passive Houses rely on insulation, air-tight construction, natural ventilation, and other features. • Features may include triple-paned windows, heat recovery ventilation systems, and solar panels. • Indoor air quality and heating needs are met through integrated Mechanical Ventilation Heat Recovery system (MVHR). • Measures include minimizing thermal bridges, air leakage, and optimal insulation levels. • Renewable energy sources used to meet energy demands - solar panels
Methods • Literature review was followed by a survey for data collection. • Survey included 4 qualitative and 10 quantitative questions based on literature review. • Respondents included homeowners/clients, design team members, and contractors. • 64 surveys were circulated with 19 responses (28.1% response rate) after four weeks. • Question Pro was used for survey creation and data collection. • Survey was distributed via email using public contact information from business websites and LinkedIn. • Quantitative findings presented in chart form.
Findings • Passive House Standard is a viable method for achieving nZEB in Ireland, as evidenced by the study findings. • Case study analysis shows success in achieving the standard's requirements, with some projects exceeding energy efficiency criteria. • Challenges associated with implementing the Passive House Standard in Ireland include high construction costs, lack of skilled professionals, and difficulties in meeting strict requirements. • Passive House standard is cost-effective, environmentally sustainable, and can reduce energy consumption, CO2 emissions, and utility bills for homeowners, while improving indoor air quality. • Government support and incentives, such as tax credits, grants, and subsidies, are needed to promote adoption of sustainable housing solutions in Ireland. • Research contributes to ongoing discussion on sustainable housing and emphasises need for collaborative efforts among government, homeowners, and developers.

‘It shouldn't really be gender specific in terms of who is responsible for change, the industry as a whole must attract more people into it as we have a shortage of resources at all levels.’
CONCLUSIONS The Literature Review and Primary Research indicated that the Construction Industry has changed a great deal over the last 50 years, however more change is required to help with the imminent skill shortages, the housing and infrastructure demands in Ireland and to create a more sustainable built-environment. According to McKinsey & Company, the benefits of gender-diverse companies are more likely to outperform the industry average. Leaning towards diversity allows companies to recruit from a wider talent pool. Achieving 25% female participation by 2030 will be very challenging, this can only by achieved through a collaborative approach that will benefit all.

The Impact of Skills Shortages on the Irish Construction Sector Matthew Kerrigan
Laura O’Donnell
S00178979@atu.ie
S00178979
Introduction
The Irish Construction Sector is a significant contributor to the countries economic growth and development. However, in recent years the sector has been facing a significant challenge – a shortage of skilled workers. This is dissertation will examine the causes of the problem, look at where the biggest shortages are, and consider possible solutions.
Aims
Carry out a literature review to gain extensive knowledge of the skills shortage the construction sector is facing • Determine what roles/professions companies are finding the most difficult to recruit • Examine the reasons why this skills shortage has occurred • Present a detailed study about the findings of the research conducted
•
An ageing workforce has been mentioned as one of the contributors to the skills shortage. The Central Statistics Office (2022) reported that the average age of construction workers has risen since the recession began in 2008. In 2006, 21% of the workforce was aged between 15 and 24, 54% were aged between 25 and 44, and 25% were aged 45 or older. In 2021, the 15 to 24 age group had dropped to 11%, the 25 to 44 age group had dropped to 45%, while the 45 and over age group had risen to 44%. Apprenticeship uptake has been increasing in recent years which peaked in 2021 when there was a record 8,607 registrations, although this still falls short of the 10,000 per year target. 2022 has seen a drop off in registrations with 8,286 according to Ohlmus (2023). The results of the questionnaire showed that 90.9% of the respondents agreed that there is an ongoing skills shortage in the construction sector. Quantity Surveyors and Engineers were among the professional roles that companies are having trouble recruiting.
Methodology
The primary method of research for this dissertation is quantitative data analysis in the form of a questionnaire. The questionnaire was distributed to a number of companies including main contractors, subcontractors, and consultancy firms. I received a large number of responses with a sample size of 22. A number of graphs were produced to provide the reader with a visual representation of the data collected
Electricians, Plumbers, and bricklayers were considered the most difficult trades to hire, among many others.
Findings
The results from the literature review showed that Health & Safety officers, Engineers and Quantity Surveyors were among the professional roles that are experiencing the largest shortage. Electricians, bricklayers, Carpenters, and plumbers were the trades that companies are struggling to recruit the most.
Other notable findings showed that 50% of respondents claimed that skills shortages are negatively impacting the cost and duration of construction projects. More than 80% of respondents claimed that college gradates were not fully up to industry standard, and 95.5% believed that a more practical learning approach would benefit university graduates entering the construction industry.
Conclusion
The shortage of skilled workers is having a damaging effect on the Irish construction sector and economy. The literature review highlights the extent of the issue and suggests that government intervention is required to further promote the industry and source talent to address the skills gap. The issue will likely be ongoing for the next number of years with additional problems arising.

Aim & Objectives
• One of the most complicated and difficult industries in the world is the construction industry. • Construction firms are therefore always seeking for ways to increase productivity and decrease waste. • Building information modelling (BIM) and prefabrication are two technologies that have lately come to the forefront as game-changers in the sector. • BIM can make it easier to integrate various building systems, including plumbing, lighting, and HVAC • Prefabrication is the process of producing construction components in a controlled setting off-site before delivering and installing them onsite.
The main aim of the dissertation was to gain a deeper understanding of the following; 1.To investigate and discuss the advancements of technology within the construction industry.
Methodology
Results
Stage 1: literature review. A detailed literature review was conducted on this topic, whereby I reviewed and analysed hundreds of paper, journals, books, articles etc. In doing so I gained a significant background on the topic and so my research broadened to stages 2 & 3. Stage 2: the pilot study A structured interview was carried out with 2 participants currently working within the industry. This insight gave me an in-depth understanding of the topic which was instrumental in developing my main survey in step 3. A questionnaire was also carried out amongst my peers. Stage 3: the main study Upon completion of the pilot study, I gained a broader understanding of people’s experience with the use of prefabrication and BIM, the study questionnaire was issued. Feedback was gathered from a multidisciplinary pool of industry workers.
• 100% of questionnaire respondents believe that BIM should be used on all projects. Both interview participants also agreed.
2. To investigate and discuss the advancements of building processes within the construction industry. 3. To outline and discuss the advantages and disadvantages of technology used within the construction industry. 4. To outline and discuss the advantages and disadvantages of some of the building processes used within the construction industry. 5. To investigate the time and cost savings that can be made using modern technology and building processes.
• 100% of questionnaire respondents believe that prefabrication increases a projects costs savings. Both interview participants also agreed with one participant stating that a 10-15% cost saving can be achieved. • 100% of questionnaire respondents believe that prefabrication has improved quality of construction elements. Both interview participants also agreed noting that working in a controlled environment with no external risks being a main factor for this. • 90.9% of questionnaire respondents believe that site safety has been improved as a result of the use of prefabrication. Both interview participants also agreed noting that working in a controlled environment being a main factor for this. • 81.8% of questionnaire respondents believe that BIM allows for early contractor involvement. The interview participants also agreed noting that early cost estimates and increased buildability as a result. • Both participants of the interview believed that the use of BIM and prefabrication together allows projects to begin at an early start date. • Both participants of the interview believed that the use of prefabrication has a time saving of 20-30%.
Conclusion • • • •

The advantages of BIM and Prefabrication can clearly be seen from both industry workers and peers. Effective implementation of both BIM and Prefabrication can improve construction quality, time savings, cost savings and also site safety. BIM has become a favourable system used throughout the construction industry as the results show. The use of prefabrication is becoming move common as the advantages out weigh the disadvantages of initial costs.

BArch in Architecture (Hons) The ethos of Architecture at ATU Sligo is a belief in the potential of architecture to transform places. We aim for a strong student-centred and student-led culture and our ambition is to impress upon the students their role in contributing to society as a new generation of architects for this area and beyond.
Human Experience and Perception of Space Our projects focus on the intimate dialogue between the user and the space they inhabit emphasising the layered relationships between the user, function, site and the spatial experience of architecture. BA in Interior Architecture and Design BA (Hons) in Interior Architecture and Design BA (Hons) in Interior Architecture and Design (Add-on) The vision of our programme stems from the core philosophical aspirations: • Care for human experience
Architecture at ATU Sligo aims to encourage students to develop an understanding of and sensitivity to historical, contextual and cultural influences on the practice of design in a local, national, and global context. Just as poetry possesses universality as well as an acutely personal sentiment, architecture provides another perspective into how we dwell, how we interact and how we seek meaning between ourselves and the world which surrounds us. We aim to build on our lineage recognizing the energy specific to this location on the edge of the Atlantic. Our philosophical approach to architecture centres on: Interpretation of Place, Regionally Transformative Architecture, Architectural Regeneration of our Built Heritage, and Human Experience and Perception of Space. Interpretation of Place Architecture at ATU Sligo draws on the existing genius loci of the north-west as an international hub of creativity, where projects, sited locally, nationally and internationally are considered from a social, environmental, historical, and cultural perspective. Regionally Transformative Architecture We embrace our role in the region as the educational centre supporting discourse and social engagement on the transformative role of architecture and exploring its relevance for future place-making, facilitating active participation of people in realising the potential of their place. We seek to raise awareness of the transcendent possibilities of architecture beyond its physical relevance, interrogating concepts of creativity and identity, and resonating with current global issues aiming to stimulate both social engagement and dialogue around the identity and creative flux of the region at this time. Architectural Regeneration of our Built Heritage Architecture at ATU Sligo places an emphasis on reading and evaluating the existing context and imprint of place, and the impact these decisions and interventions have on the regeneration of place, using principles of environmental, social and cultural sustainability. atu.ie
• Inspired, environmentally conscious response to place - community, location, culture • Creative communication and global engagement. We offer accessible experiential learning that fosters creative, versatile and ethically aware designers with developed collaborative and communicative skills. Our Interior Architecture and Design programme focuses an environmentally conscious approach to the re-use, re-imagination and innovative re-invention of the existing built environment with a strong focus on sculpting interior space. Our students are challenged to offer imaginative responses to spatial problems, which cut across interior architectural aspects of place, cultural and built heritage and recognise the design needs and identity of clients. Through interactions with live clients, real sites and diverse design projects our students learn to position urgent stories in a coherent spatial and sociological narrative. Memory, identity and sense of place along with the intrinsic qualities of community and culture are explored and often juxtaposed with a global context, to inspire resonant, sensitive and rich design projects. The Interior Architecture and Design course at ATU Sligo provides an internationally recognised level of education and training aligned with European Council of Interior Architects standard and best practice across Europe. Our graduates are ethically and professionally motivated, to be innovative, responsible and versatile design professionals, inspired by current knowledge of the design world, equipped with an industry ready creative and technical skill-set and experienced in design collaboration.

Results & Conclusions
Methodology Background Remote patient monitoring is the future of healthcare as more devices are connected to the Internet of Things (IoT). Studies have shown that there are many benefits to patients using medical devices with remote monitoring capabilities, leading to a reduction in the need for hospitalisations. [1] The purpose of this study was to implement remote patient monitoring in a medical device. Respiratory intervention was the area of focus for this research, specifically non-invasive ventilation. According to COPDSI 3,685 patients suffering from Chronic Obstructive Pulmonary Disease are hospitalised yearly in Ireland. These patients typically spend an average 9.5 days in hospital. [2] High oxygen therapies are generally administered on hospitalisation. An investigation into acquiring patient data and delivering it to a cloud service was conducted with the end goal of being able to administer high oxygen therapy at home.
My implementation focused on taking live patient data from a Non-Invasive ventilator and uploading to a cloud service. Voltage readings of the flow sensor on the CPU board of the ventilator were acquired in real time via a programmable, Digital Multimeter and translated into useable patient data using LabVIEW. Those results were then sent to a cloud service (ThingSpeak) vis HTTP. The idea was that a Clinician could log in any time and monitor their patient. Email alerts were set to notify of the patients Inspiratory Capacity declining below a clinically defined setpoint – a key indication of a COPD flare up The theory is this could allow a clinician to administer High O₂ Therapy at home before hospitalisation.
Live Patient Data was successfully obtained. This Research showed that Remote Patient Monitoring of Ventilated Patients at home is possible. Limitations - use of a DMM was great for Proof of Concept, but something more robust such as a Data Acquisition Device can be used for faster data acquisition. The future work for this project is very exciting, Such a cloud system for remote monitoring and control could be integrated with patient Electronic Health Records to develop a clinical decision support system. This would lead seamless integration into a patients record to aid a clinician in making a decision, aided by remote patient monitoring

Introduction
Methodology
Results
The manufacturing industry of the global economy is important because it deals with the manufacture of goods employing a range of technologies, processes, and raw materials. The sector is essential for fostering job growth, generating income, and stimulating the economy. The manufacturing industry includes a wide range of subsectors, such as consumer products, food and electronics, beverage, aerospace, automobiles, and electronics. Manufacturers must employ cuttingedge technology like automation and robots to stay competitive. The industry also tries to provide the safety of the workers, and the sustainability of the environment.
The Methodology of robotic arm, first the arm, The Tinker Kit Braccio arm use the Arduino software system to be programmed. The arm is propelled by five servo motors. The tiny servo motor is made of aluminum brackets and plastic parts. The arm can lift to 400 g and has a maximum reach of around 53 cm. This arm use Arduino to be regulates how it move to transport goods from one location to another. This arm can be added to it some components like in this project for example sensers & pixy 2 camera to be able to see the given tasks. For the control system, the robotic arm control system generally consists of a combination of hardware and software elements that cooperate to plan the movement of the arm and its functions so that it can perform the tasks assigned to it. For the robotic arm to move, the control system hardware will use sensors, actuators, motors, and other electrical components been used. Algorithms and computer codes embedded in control system software components often allow the arm to perform specific functions and respond to commands. These software elements might include path planning algorithms, motion control algorithms, and software interfaces that let a client or other system operate the arm. For this project the software is Arduino. After all the components is add together it placed on a factory then start to work by the camera (pixy 2) see the coming objects then it sends the data to the Arduino so it can give the commands into the servo motor so the arm can move and take the parts to it places.
Despite the numerous challenges the project has faced, the outcome was successful. The Arm and the Pixy camera are programmed using the Arduino software. After that, the motors are switched out with DC motors, which are considerably easier to program.
The Motion sensor robotic arm project is a project to build and programme by using an Arduino board to make it able to transfer objects from one end to another using a vision system called pixy2 camera.
Research Before starting the current project, I thought about a lot of ideas and research until the current project was approved by the supervisor. I did extensive research and study before starting the current project. When it was approved, there were a few points to look out for as they are among the tasks most critical to my ability to finish this project by the deadline. These research objects are the following: 1. Materials 2. Robotic arm
atu.ie
The motors moved as they should have once the Pixy camera recognized the objects on the board. The robotic arm's six servo motors were all successfully able to move.
Conclusion In conclusion, the motion sensor robotic arm has done it manufacturing purpose by the camera (pixy 2) see the coming objects then it sends the data to the Arduino so it can give the commands into the servo motor so the arm can move and take the parts to it places.

Introduction Palletizing is used very commonly in the industry for example most factories would often have a palletizing cell to cut labour costs and human error. This project aims to replicate what would be used in industry. This machine has the ability to not only palletize but also to distinguish between two different parts.
Methodology
Results
Programming: The following are the steps in which the ladder logic programme will be carried out; • Part is placed by the operator into the chute. The cylinder then pushes the part out onto the conveyor. • Once the part is on the conveyor it will travel to the camera and an image will then be taken. • Once the image is taken it will send a signal to the PLC. The PLC will communicate with the robot telling it if it is a Circle or square, the Robot will then pick and place the part. • The image below is our network layout:
Research We decided to use an Allen Bradley PLC as they are common in industry and experience with them would come in useful once we leave college and begin to work in industry. ABB are a leading manufacturer in industrial robotics and almost every workplace in Ireland that uses industrial robots would have an ABB. We decided to use an Omron FQ camera for part detection.
• The Robot was successfully executing the routines that we created. • The FQ2 Camera is scanning parts and communicating with the PLC. • The Parts funnel feeds parts as planned.
Conclusion
This project was extremely beneficial towards both our engineering careers, PLC programming and robot programming will be very beneficial to us when we go into industry. We did however find the programming and manufacturing of our project more difficult then we first presumed.

To prevent injury due to orthostatic hypotension using an automated compression response system. Jack Quinn, Evan Oates S00210124@atu.ie, S00212337@atu.ie
Jamie Roche, Dinesh Duraibabu, Aonghus Murphy
Introduction
Results
Elderly people are often victims of falls due to fainting caused by orthostatic hypotension. This occurs when the walls of the arteries at the lower extremities weaken with age and cannot force blood back up to the heart. What this means is blood will pool in the lower extremities and therefore deprive the brain of oxygen leading them to faint.
The completion of the data collection needed to create a model for our project was successful obtained by ethical means. This was the first goal we successfully completed. The calculation of the users PTT was also completed, this in turn allowed the modelling of our systems main function to be created too. This completed our second goal. The completion our third goal was successfully achieved. We were able to pass the PTT value through a regression model that gave us an accurate BP reading. Finally, we were able to identify any dangerous readings from the live feed from the sensors. When these values were identified the system would then notify the user that the compression system needs to be actuated. The systems compression system also actuated efficiently when prompted to.
Conclusions & Recommendations
Figure 1 – Different measurement points of PTT
Methodology To collect the necessary data from a variety of people, consent forms were obtained and distributed to any individual that consented to having their data collected. The data collection was carried out by using an ECG, PPG and BP monitor simultaneously. This gave the actual BP of the individual that we would be our aim value to obtain. To do this we calculated the PTT from our ECG peak values and PPG peak values obtained from the project's sensors. This data was then used to compare our live readings to. The collected data was all from individuals that did not have any past issues with orthostatic hypotension so the assumption of safe ECG and PPG levels can be made.
Figure 3 – Layout of Project Body
Research Aims & Objectives • To collect the ECG, PPG and BP measurements to develop a model to continuously monitor BP. • To calculate a person's Pulse Transient Time (PTT) using the ECG and PPG sensor readings. • To put the PTT value through the regression model to get a BP reading. • To identify dangerous readings from an individual's live readings and actuate the compression system.
The “unsafe” ECG and PPG trend then needed to be identified. This was done by identifying a decreasing trend in the ECG and PPG levels which would cause a lower PTT. These types of trends would actuate the system. Any readings that continuously decreased would cause the system to actuate and compress the abdomen. Figure 4 – Project Body
Figure 5 – Layout of Project Body Figure 2 – Body Tunic / Compression System
To conclude, we successfully obtained data, created a model from that data and created an regression model that can consistently identify peak values and calculate the PPT from these figures. We were also able to identify unsafe PPT value trends used to notify the user to actuate the compression system autonomously. If this project were to be done again a faster air pump would be ideal as this would reduce the delay between low BP detection and the compression of the abdomen.

Abstract The primary objective of this project is to design and implement a quadcopter drone capable of conducting simultaneous localization and mapping (SLAM) techniques in areas void of GPS, thereby enhancing its navigational capabilities in challenging environments. The flight control system is managed by a microcontroller, which leverages software-based PID controllers to adjust pitch, roll, yaw, and altitude. To achieve precise orientation estimation, Kalman filtering is utilized in conjunction with the inertial measurement unit (IMU). The SLAM process is executed on a Raspberry Pi equipped with ROS, which collects LiDAR data and offloads processing and visualization tasks to a remote PC.
Research A significant amount of research was conducted to ensure the successful development of the vehicle. The research process involved investigating various topics such as: • • • • •
Multi-copter Design Control System Design Filtering and Sensor Fusion SLAM Techniques ROS (Robot Operating System)

Student ID: S00232627
Introduction
The trades have been dealing with a continuous decrease in laborers for decades (Rock, 2012), and I know from experience that there is an overabundance of repetitive tasks that can be replaced by an automated tool. With over three years of professional working experience in the trades and a keen interest in the automation industry, a sharp insight has been gained into which tasks can be replaced by an automated machine. The Voice-Controlled Automated Apprentice (VCAA) aims to fix this issue by providing a helping hand. This machine cuts plastic pipe to specific lengths based on measurements received through voice-input by using speech recognition.
Neural Network
This machine uses a Convoluted Neural Network (CNN) for its speech recognition system. A CNN functions by analysing images. To be used for audio input this neural network transforms the audio waveform into a spectrogram as seen below.
Jamie Roche Aonghus Murphy
Results
The Convoluted Neural Network worked as desired and was able to operate the system effectively and was able to interpret the spoken word with good accuracy when tested. The custom designed pipe-feeding system functioned effectively to move the pipes a precise distance.

Introduction Vision Systems Many poor and war-stricken countries don’t have access to the same quality of surgeons and equipment as the rest of the world. Telesurgery solves this problem by utilizing robotic technology to perform surgery wirelessly from a remote location. Our aim is to create a robotic arm that can be controlled through a motion capture camera to replicate telesurgery.
Vision Systems The vision system we used was Leap Motion. We used the motion capture camera to track the movement of our hand and send the signals to the robot that will replicate our actions.
Code The code we used for this project was C++ and Java. The Arduino is used to programme the motors and Java is used to programme the camera. By using serial ports and the Arduino Firmata Library we tried to integrate the two to allow the camera to communicate with the Arduino, so when a certain movement is detected the assigned motor(s) activate.
3D Printing
Vision Systems The vision system we used was Leap Motion. We used the motion capture camera to track the movement of our hand and send the signals to the robot that will replicate our actions.
For the building of our robot, we utilized the models on the website ‘InMoov’. We printed off the necessary parts on the 3D printers that were available to us in the college. We assembled it in the college during lab hours.

Introduction
Methodology
For our project we hoped to develop a concept that will allow the user to travel freely throughout the isles with their shopping trolly behind them. Our main aim was to design a product to keep an optimum working distance that is convenient for the user to shop and walk without interference or hinderance.
The project aims to use a vision sensor and an anti-collision system to control the pace and direction of a trolley.
We used a HuskyLens camera as the main tool to send a signal to the servo motors on the trolley to direct it where it needs to go.
The project requires extensive research, troubleshooting, and problem solving to achieve a safe standard for public use. The original program libraries used for the trolley include an object tracking library and a servo library code to control the direction of the front wheels.
The trolley is also fitted with multiple ultrasonic sensors to ensure that the trolley itself doesn’t collide with anything that blocks its path whether that be a customer of loose product on the shop floor.u
The flowchart associated with the design of the product shows how it will react to the different environments and obstacles that the trolley will face. It is also a good reference for the designer to keep him/her on the right path and avoid distractions or going away from the end goal when building the automated trolley. The code above uses the information received from the vision sensor to control the left turning mechanism of the trolley. From a starting position of ninety degrees the servo motor will move one degree less until it reaches fifty degrees with a delay of fifteen milli seconds depending on the coordinates of the object in the lens of the vision sensor.
Results We ran into issues regarding the code as we struggled to get the different libraries to all work in sync which in turn slowed down the process of getting all to work together. With the code we have, in theory it should work but we just need to sort out those few teething issues before the project is fully complete.
Research Some points of research include: • Speed Controllers • Servo motors • Arduino Mega 2560 • Vision Systems • Ultrasonic Sensors
Conclusion
The collision avoidance system will use ultrasonic sensors to detect obstacles or people and stop or move the trolley away from them. However, initial testing using lights on a breadboard did not yield accurate results.
Overall, the project while it threw up various problems at different stages of the design and build was a success in our eyes. The problems we encountered in amalgamating the various codes together forced us to look at different avenues of control while all the time learning through the trial and error and research combined. Regardless of these obstacles we were able to build a concept that hit all the objectives we set out in the proposal.

Overview
• The mismatch between the stiffness of solid implants and bone causes detrimental shear stress in the bone-implant interface, bone resorption, and implant loosening (the stress shielding effect). • Porous structures have considerably lower stiffness than solid, dense structures so the applied loads can transfer to bone tissues and according to Wolff's law accelerate bone ingrowth, bone remodeling, and implant fixation. • Porous implants are also beneficial for cell seeding, migration, vascularization, and mass transport of nutrients from and to the cells.
Bone morphology
Porous cell samples with different porosities; CAD models (A, B, C); Additive manufactured samples (D, E, F) and their elasticity modulus calculation [3]
Topology optimization implemented by FEM
• Topology optimization is a structural optimization technique that optimizes the distribution of the material in a specific design domain and can be carried out by collective use of Finite Element Method (FEM) concepts and different optimization algorithms • The most implemented, primarily accepted, and mathematically well-defined interpolation methodology is the SIMP model.
• Bone consists of the outer cortical bone and the inner trabecular bone. • Trabecular bone consists of cellular structures with 55-70% porosity.

Introduction
Aim of Project
▪ Microplastics are ubiquitous in the environment. There are emerging concerns about their impacts on human health and the environment (Khant & Kim, 2022). ▪ Microplastics can be ingested directly by drinking water or indirectly from food preparation and bathing (Wright & Kelly, 2017). ▪ The direct health impact is still not well established. However, microplastics can act as vectors for toxic pollutants and microorganisms and pose severe risks (Campanale et al., 2020).
▪ The traditional method used to sample microplastic has several limitations, including having low spatial and temporal coverage and being costly, tedious and timeconsuming. ▪ The overall aim of this study is to develop a novel tool for tracking and assessing freshwater vulnerability to microplastic pollution at a fine temporal resolution. ▪ This research proposes a framework to monitor microplastics in freshwater in real time by applying integrated machine learning, GIS, remote sensing, statistical downscaling, and low-cost sensors. ▪ The study is motivated by the availability of low-cost cameras, internet and cloud computing services

Aim and Objective
To design and implement efficient communication models and protocols for rapid and self-organized disaster response networks.
Motivation • • •
Natural disasters are unpredictable events which can occur anywhere and anytime. Victim’s life can be saved if timely response is provided. In these events Victim’s needs to connect to outside world and be traced, and responders needs to deploy a rapid communication network and communicate with each other to provide rapid and efficient response.
Background • •
Disasters are not same in nature and can partially or full destroy the existing network infrastructure which can result in different challenges for responders. To cope up with this, first responder communication should have some requirements such as, self-organization, rapid network deployment, coverage, path planning and optimal decision making for search & rescue operations.
• Types of disasters • • • • •

Problems
There are many challenges, few of them are as follows, • Existing network could be partially or fully damaged. • Timely search and rescue operation with optimal path planning and optimal delay requirements. • Rapid deployment of a temporary network within first 48 hours, until a more stable help arrive. • Self-organization and management of provided communication networks. • Quality of service for including throughput, delay, and transmission rates. • Link establishment • Efficient spectrum selection, utilization, and management • Backhaul connectivity
Preliminary solution
• Following are the two possible challenges and scenarios. • •
In figure 1, victim is lost or trapped, and responders' job is to find/trace victim using an optimal path and with minimum delay. In figure 2, responders' job is to deploy a rapid and self-organize network to establish communication between responders and victims.

Biodegradable polymer implants • Biodegradable polymers are the types of polymers that degrade via hydrolysis • Implants (medical devices) made from biodegradable polymers are bioabsorbable • Bioresorbable implants provide temporary mechanical support in areas of damaged tissue • Biodegradable polymers coupled with 3D printing make patient-personalized implant manufacturing easy • With suitable polymers, medical devices can be printed anywhere • Polymeric devices get absorbed through hydrolytic degradation (see diagram below)
Methodology • A mathematical model was used to capture the concentration of hydrogen ions from the beginning of the degradation process to the end Result • In this work, the actual concentration of hydrogen ions is estimated through a mathematical model • The consideration of hydrogen ions produced at the long chains, short chains, and the ions that diffuse out of the system at the surface are taken into consideration • The model proposes a relation for the actual concentration of hydrogens ions by introducing a new diffusion term • The diffusion term captures the electrochemical potential and valency of hydrogen in the system • The hydrogen ion concentration model is shown below
The degradation of synthetic polymers through hydrolysis (Li et al., 2019)
Degradation of Polymeric Implants • The degradation of a biodegradable implant starts immediately upon implantation • During this process, water attacks ester bonds leading to chain scission and the production of short and long polymer chains • The carboxylic end of the polymer dissociates hydrogen ions which accelerate the reaction, hence rendering the process autocatalytic • The process leads to the loss of mechanical properties and loss of mass (see graph below)
Interplay between material properties and material degradation (Li et al., 2019)
Acknowledgment
Expected Impact • This model will monitor the concentration of hydrogen ions during the degradation of polymeric devices • It may be used to control the concentration of hydrogen ions in simulation • It will give a better understanding of the underlying mechanisms by which polymeric devices lose mass • It will help in predicting degradation rates of the polymeric structure

Background
Additive Manufacturing offers more design freedom for injection mould tooling, enabling greater use of conformal cooling channels and embedded sensors. There are however concerns about the durability of AM manufactured mould tools as they are required to operate in harsh environments that demand a high number of production cycles. This project aims to deliver instrumented AM mould tools for tool health monitoring and mould tool defect identification such as wear, fatigue stresses, cracking, cooling channel blockages, etc.
Sensor Integration
The tested sensors were integrated into the design of the conventional cavity inserts. The installed sensors collected data during the normal operation of the process to provide better understanding of their behaviour and the amount of background noise collected.

INTRODUCTION
atu.ie
This research explores sensorised injection mould tools that used in conjunction with modelling strategies for: Component quality prediction and control over critical component quality attributes such as shrinkage and warpage. Tool condition monitoring (TCM) to detect critical tool failures establishing confidence in the technology for injection moulding Optimised component cooling through conformal cooling channels (CCC) assessing effects of the additively manufactured (AM) surface roughness on heat transfer in a turbulent flow. The Sensorisation research explores novel strategies for embedding a wireless Surface Acoustic Wave (SAW) sensor in an AM cavity. Structural lattice design (cavity light weighting) to reduce the weight of the cavities, reducing their overall cost and material consumption and reducing the print time. Post-processing techniques using AM copper electrodes for sink EDM of the main component cavity in the AM tooling.
Conformal Cooling design, simulation and surface roughness modelling: Final design iteration of the CCC was simulated in MoldFlow (Figure 3). AM surface roughness was modelled and simulated in Ansys - Fluent allowing a correlation between flow and heat transfer.
Cavity lattice design and data collection to date: To fully exploit the design freedom of AM, a lattice design was incorporated to the cavity, designed to withstand 45 Ton force (Figure 6). Moulding and defect tests were performed on the sensorised mould and data retrieved (Figure 7).
METHODOLOGY AND RESULTS
Sensorisation & embedding a wireless SAW sensor: Sensor selection and location (Figures 1 & 2) were based on simulation results from the conformal cooling modelling work identifying hot spots and critical locations.
CONCLUSION
This research has successfully embedded sensors into additively manufactured 316L stainless steel injection mould tools. The design and performance simulations for the printed tooling and CCCs have been completed as has simulation work into the effects of additively manufactured surface roughness on heat transfer in various flow regimes. The cavities were successfully printed and trials of an AM copper EDM electrode have been successful. Using lattices, lightweight cavities have been designed and are currently being printed, resulting in ~40% weight reduction in the cavities. Embedded sensors have been proven to be effective in providing data on part quality and tool condition in a real process. Next Steps: Complete experimental work for each branch of the research and evaluate against previous simulations. Use collected sensor data to develop models and data processing strategies and evaluate AM cavity performance. Continue research into precision post-processing techniques.

Laminar flow Transitional flow Turbulent flow (Re < 2000) (2000 <Re < 3000) (Re > 3000) Fig. 1. Flow regimes: laminar, transition, turbulent flows
In typical flowrate injection moulds, the flow of cooling fluid is turbulent flow with a Reynold number between 4000 to 15000. However, in conformal cooling applications, the flow regime can be laminar. Therefore, the impact of roughness on both laminar and turbulent flow regimes is of importance.
NUMERICAL STUDY
atu.ie
A series of numerical simulations were performed to study the influence of AM roughness on heat transfer and flow friction in laminar 𝑅𝑅� = 7.1 𝜇𝜇𝜇𝜇 and turbulent flows in rough channels. A numerical model was developed to generate random roughness based on 𝑅𝑅� = 11.9 𝜇𝜇𝜇𝜇 the statistical parameters of roughness. Fig. 2 show numerically generated roughness with the Gaussian distribution used in the 𝑅𝑅� = 17.1 𝜇𝜇𝜇𝜇 computational studies. The rough surfaces were used in a channel shown in Fig 3. and modelled in ANSYS–fluent to simulate heat transfer and Fig. 2. Numerically fluid dynamics. generated roughness As illustrated in Fig. 4, in laminar flow, roughness can enhance heat transfer up to 46%, with only a 3% friction penalty. However, in the channel with low roughness.

In turbulent flow, as shown in Fig. 5, roughness can lead to heat transfer enhancement of up to 36 % and a friction increase of up to 40 %. The increase in heat transfer with Re tends to reach an asymptotic value, after which increasing the Re (flow rate) has no impact on heat transfer while it increases the friction in channels, demonstrating the existence of an optimum Reynolds number in rough channels. 50 40 30 20 10 0 -10

Surface roughness is a natural consequence of Additive Manufacturing (AM) processes that requires consideration within the design of internal cooling channels fabricated by AM.

EXPERIMENTAL STUDY
Geometrical factors (e.g. channels cross-section and channel diameter) and AM related parameters (e.g. build orientation) can impact AM roughness. Two experimental rigs (one in ATU Sligo and one in Siemens Energy, Sweden) were built to study different roughness and channel parameters, which is currently being in progress.
Fig. 6. Convective flow rig in ATU Sligo
CONCLUSION
Roughness positively influences heat transfer and negatively impacts the friction (pressure drop) in cooling channels. The effect of roughness varies with the flow regime with better performance in laminar flow, providing a heat transfer enhancement almost 15 times greater than the resulting friction penalty. However, in turbulent flow, the heat transfer enhancement is almost the same order as friction increases, leading to a 36% heat transfer enhancement compared to a 40% friction increase. There is an optimum value for the Reynolds number for rough channels with a certain roughness that any increase in Reynolds number more than the optimum value leads to only friction increase without noticeable heat transfer improvement.

INTRODUCTION This research is focused on embedding in-mould sensors in injection moulding tools for real-time monitoring of part quality and advanced process optimisation. The project aims to improve precision and reduce cycle times in injection moulding. CURRENT RESEARCH SENSORISATION Kistler thermocouples & pressure sensors, classic and customised ultrasound sensors and a thermal camera were chosen for collecting data from the actual process. A thermal camera is a fast approach for monitoring temperature maps and identifying part defects. Customised ultrasound sensors have some advantages over classic ultrasound sensors, such as being hightemperature resilient, non-invasive and miniature. The sensors were placed in conventional mould tools, and 3D printed mould tools with conformal cooling channels.
CURRENT RESEARCH OPTIMISATION RESULTS Collaborative development of conformal cooling channels (CCCs) based on hot spot locations with conventional drilled channels. Use of Moldflow simulations for comparison of the efficiency of both channel designs (Fig. 4 &5). Validation of the simulation result by actual experiments for the conventional mould tools (Fig. 6).
A comparison of classic and Adaptive DOE, facilitated by real-time sensor data, showed superior performance of ADOE in multiobjective optimisation of part quality and cycle time in just over half the number of experiments.

CONCLUSION & FUTURE WORK
Conventional mould tools with drilled channels, embedded thermocouples, and a pressure sensor were manufactured and tested in the actual injection moulding process. The sensor data validated the simulation result for temperature distribution in the part. Simulation comparison of the drilled channels with CCCs indicated the ability of the CCCs in reducing the cycle time and providing even temperature distribution. Adaptive DOE and Central Composite Design were compared and the superior performance of ADOE was validated. The future steps are: 1. 2. 3.
Validation of AM conformal cooling channel design via embedded sensors. Embedding of customised ultrasound sensors into the mould for monitoring part morphology. Development of a Digital Twin based on a state estimation framework for real-time dynamic optimisation of the process.
