    <title language="eng">Evaluation of Efficiency Measurement Uncertainty in Hydraulic Test Benches Across Different Locations</title>
    <abstract language="eng">Purpose: The objective of this thesis is to evaluate the uncertainty of efficiency measurements in hydraulic pump testbenches and to validate the upgraded hydraulic functional testbench at the LocationY plant (LoY) against established reference testbenches in LocationX (LoX). The study focuses on volumetric and hydro-mechanical efficiency measurements of external gear pumps and the main aim is to assess measurement comparability using a standardized, uncertainty-based approach.&#13;
&#13;
Methodology/approach: The methodology is developed based on the theoretical foundations of the “Guide to the Expression of Uncertainties in measurement” (GUM) (JCGM 100, 2008) in combination with other sources. Type A uncertainties were evaluated using 25 repeated measurements at static operating points and Type B uncertainties were derived from calibration certificates, sensor specifications, expert review, etc.</abstract>

    <title language="eng">Development of a CANBUS network for RoboBoat</title>
    <abstract language="eng">Autonomous marine vessels have seen use since as far back as World War I, with the Imperial German Navy’s Fernlenkboot. Such vessels find more modern use in the logistics sector and as survey vessels, where the continuous operation made possible by autonomy provides distinct advantages in their respective tasks and industries. This thesis presents the development of a CANBUS-based internal network for the RoboBoat autonomous surface vessel project of the Rhine-Waal university of Applied Sciences. It is designed to be the basis on which further development of on-board electronics can take place. It will also act as a platform for further development of the RoboBoat itself, as well as for future projects by students of Rhine-Waal University’s FabLab Blue that require such communication architecture. The resulting network is built around the NMEA 2000 standard and off-the-shelf microcontroller boards and network cables, which have enabled quick and fairly robust communication between the different control modules employed in the prototype. NMEA 2000 was chosen owing to its compatibility with modern marine hardware like the multi-function displays, as well as for a simple path to backwards-compatibility with older, less expensive NMEA 0183 hardware. The development process incorporates the systematic process of Engineering Design by G. Pahl and W. Beitz, which guides the processes used here to make various design decisions.</abstract>

    <title language="eng">A Computational Study on the Effect of Water-to-Air Volume Ratio on Water Rocket Performance.</title>
    <abstract language="eng">This thesis presents a three-dimensional computational investigation into the influence of the water-to-air volume ratio on the flight performance of a water rocket. As a critical design parameter, this ratio fundamentally governs the trade-off between available propellant mass and expansion energy, and thereby dictates the rocket's achievable altitude and range.&#13;
&#13;
A comprehensive numerical model is developed to simulate the complete trajectory through its three principal phases: water expulsion, compressed-air expansion, and ballistic flight. The governing equations, derived from the conservation of mass, momentum, and energy, are solved using a fourth-order Runge-Kutta (RK4) scheme. The model incorporates variable mass effects, aerodynamic drag, gravitational forces, launch geometry, and ambient wind conditions. Implemented in MATLAB with a modular graphical user interface (GUI), the simulation framework facilitates systematic parametric studies.&#13;
&#13;
The numerical predictions are validated against experimental launch tests conducted at elevation angles of 60° and 77°. Maximum altitude and horizontal range are extracted from multi-camera recordings using image-based analysis. The results demonstrate strong agreement, with both approaches converging on an optimal water fill fraction. The simulation identifies an optimum of approximately 43%, while the experimental measurements indicate a slightly higher optimum of 45.5%. Considering the collective evidence, an overall optimal fill range of 40 to 50% for 250 mL water rocket bottle, is established. The consistency between computational and experimental findings validates the robustness of the proposed model and confirms the identified optimum as a reliable benchmark for water rocket performance.</abstract>

    <title language="eng">Development of Sustainable Nanofibre Wound Dressing Using Solution Blow Spinning.</title>
    <abstract language="eng">This thesis investigates the production of polylactic acid (PLA) fibrous mats using a low-energy, airbrush-based solution blow spinning (SBS) method with dimethyl carbonate (DMC) as a greener solvent. The study addresses how changes in PLA concentration and air pressure influence fibre formation, fibre diameter distribution, and non-woven mat structure, and examines the implications for incorporating tea tree oil(TTO) and pectin into the resulting materials.&#13;
PLA solutions in DMC were prepared at multiple concentrations, and the SBS process was evaluated using realistic deposition observations and calculated estimates of material consumption.&#13;
Fibre morphology was analysed by scanning electron microscopy (SEM), revealing fibrous structures and parameter-dependent differences in diameter distributions and mat heterogeneity.&#13;
Chemical structure was assessed via FTIR spectroscopy, which indicated that the produced fibre mats were dominated by PLA-characteristic spectral features (and possible DMC contributions), while providing limited evidence for substantial pectin or TTO contributions in the measured spectra under the tested conditions. Thermal analysis (STA) was used to interpret important PLA thermal transitions and to identify possible traces of composites within the fibres. A qualitative hydrophilicity approach based on&#13;
water droplet wetting behaviour was applied as an initial indicator of surface wettability and potential pectin effects, while recognising its limitations compared to full contact-angle measurements.&#13;
&#13;
Overall, the results support SBS with DMC as a viable route to produce PLA fibrous mats and show clear process–structure relationships. However, they also show that better mixing methods and stronger confirmation evidence are needed at every step of the characterisation chain in order for additive incorporation to work.</abstract>

    <title language="eng">Implementation of Bayesian Optimisation for FEM Simulation</title>
    <abstract language="eng">Optimisation of engineering problem involving FEM simulations is time consuming especially when dealing with high-fidelity structures. The conventional methods of searching and exploring the design space such as grid search or golden section search require a lot of evaluations before converging on an optimal solution. When there is a time constraint, the final solution found could be suboptimal due to the vast amount of FEM simulation necessary to converge. Therefore, with the utilisation of probabilistic surrogate models such as Gaussian process regression to reduce the amount of computation necessary. Surrogate models approximate unobserved areas in the design space based on the observed data. Together with the use of acquisition function to select the next observation point, it forms this optimisation method known as Bayesian optimisation. This research aims to implement Bayesian optimisation method in a few test cases involving FEM simulation to compare its performance against conventional methods. The results from the test cases showed that Bayesian optimisation converged up to 12 iterations faster compared to convention-al optimisation methods. It also provided a better optimised solution in a multiparameter optimi-sation problem with constraints.</abstract>

    <title language="eng">Designing a Launching System for a Robotic Boat</title>
    <abstract language="eng">Based on the learning in this degree program, the author was tasked with developing a transport system for the current research boat, called Roboboat. The aim was to examine the components and reverse engineer them to calculate the mechanics of the boat. Because no design or measurement data were available, this thesis began by modeling the boat. After modeling, a literature review was conducted, and a launch system was designed with a focus on utility and cost-effectiveness. This report presents the design process, calculates the stress and strain on the design elements, and presents the concept of a launch system.  Finally, the stability of the boat is calculated, and the mathematical validation of Roboboat is presented.</abstract>

    <title language="eng">Strategic Obsolescence Management: Developing a Process-Oriented and Financially Viable Concept</title>
    <abstract language="eng">Industrial machinery is designed for long operating periods, but many electronic and mechatronic components used in these systems are discontinued after a short product lifecycle.&#13;
This situation causes challenges for Strama-MPS, especially in the Global Service division, where long-term spare-parts availability and reliable customer support are required. When components are no longer available, urgent procurement, redesigns under time pressure, longer downtimes and higher service costs put additional load on internal departments and can negatively affect customer relationships.&#13;
This thesis develops a structured and financially viable approach to obsolescence management for Strama-MPS. The current situation was analysed using expert interviews and SAP and PRO.FILE data for the period 2018 to September 2025. The evaluation of more than 13,000 obsolete materials showed fragmented communication, insufficient lifecycle documentation and that only a few large suppliers systematically send PCN notifications, while many others do not. To summarise the results, a Power BI dashboard was created that shows portfolio age, part criticality, successor availability and supplier concentration. The analysis identified an average part age of 6.75 years, a cost-at-risk of around €1 million and a high-risk group mainly consisting of electrical and control components.&#13;
In a second step, the active parts portfolio was evaluated to identify future risks. Using manually cleansed Excel files and Power BI models, a lifecycle forecast was developed for the period 2026–2029. It highlights early-warning patterns in connectors, sensors, I/O modules and control units with short technology cycles and high dependency. These results enable earlier evaluation of alternatives, more controlled last-time-buy decisions and more proactive customer communication.&#13;
Based on these findings, the thesis proposes a target framework in line with DIN EN IEC 62402:2025-05. It defines responsibilities, decision and communication paths, and workflows between the relevant departments. A dedicated Obsolescence Manager is assigned as the central process owner and is supported by SmartPCN-compatible input formats, lifecycle dashboards and an implementation plan that starts with an internal pilot and later includes the roll-out of PCN Global as the OM software.&#13;
The strategic options were assessed using an MCDA, comparing reactive, proactive and strategic approaches. The results show that a dedicated role combined with suitable software offers a good balance between cost control, early-warning capability and acceptance. The financial analysis indicates that the concept can pay back within the first year by reducing emergency sourcing, redesign work and service delays, while also improving collaboration,&#13;
decision quality and long-term service performance. Overall, the proposed structure provides a clear basis for more consistent and reliable lifecycle handling across the organisation.</abstract>

    <title language="eng">The effect of shearing in a twin-screw extruder on the mechanical properties of biopolymers (PLA+PBAT) using varied screw designs</title>
    <abstract language="eng">The primary aim of this research project was to determine the effects of shearing on the structure of a blend of biopolymers (PLA+PBAT) through tailored screw designs in a twin-screw extruder. To achieve this, 3 different twin intermeshing co-rotating screw designs of an extruder were used. The designs were mainly focused on the kneading and mixing part of the screw which has a shearing effect on the biopolymer. The experiments were carried out by keeping the temperature, screw speed and feed rate constant. To carry out the experiment, a 60:40 blend of PBAT and PLA was utilized.&#13;
The compounded pellets produced from the 3 screw designs were then used in a Blown Film machine. Furthermore, tensile test was conducted on the resulting samples. The shear strength and strain of the films were calculated. Tear test of the films were additionally carried out to validate the findings. Fourier Transform Infrared (FTIR) test was conducted to study the functional groups, identifying the chemical interactions and phase compatibility of the of PLA&amp;PBAT blend.&#13;
The results showed that the screw with 3 kneading blocks (HS) and 2 kneading blocks (MS) exhibited almost similar ultimate strength and ultimate strain. The screw design with only conveying elements had lower ultimate strength and strain. The kneading blocks played a role on the mixing and shearing of the biopolymer structure in the blend.</abstract>

    <title language="eng">Design and Implementation of a Virtual Gearbox</title>
    <abstract language="eng">This thesis represents the design and implementation of a virtual gearbox functionality as a system with an end goal to be used on the Electric Gokart platform.&#13;
The design includes a 3-part solution consisting of:&#13;
&#13;
- Human-machine interface (HMI) – that is a physical hardware as a separate unit with its own housing&#13;
- Intermediary software for transfer of input information and output feedback of the user – as software code &#13;
- Control Model – MATLAB Simulink model to be run on the main computer of the platform to facilitate the motion control &#13;
&#13;
Due to the system complexity and multidomain solution the work has been broken down and documented to focus on a specific aspect for each deliverable. The human machine interface focuses on the hardware aspect of the functionality – research on and  evaluation of different components for the input, feedback and communication and the impact of each component to the further development of the intermediary software. The software part is focused on choosing and implementing an efficient and logical handling &#13;
of the sampling and relay of information to prevent the potential problem of &#13;
communication network overload. And finally, the Simulink Control Model will focus on investigating input information, processing and motion control realised via torque control. The information is to be used used in developing a system response model evaluating it on the prototype and allowing tuning via system identification in the MATLAB Simulink development environment.</abstract>

    <title language="eng">Development of selection criteria and systematic methodology for the design of novel hydrogels</title>
    <abstract language="eng">Hydrogels are a broad field of materials with applications in many niche areas. To advance the state of the art, research should explore new combinations of chemical and practical components to discover syntheses with novel emergent properties. However, given the vast amount of information available, it is challenging to systematically narrow the search to an effective comparison of a few select candidates. &#13;
This work proposes a selection and evaluation methodology for building a comparative scope to decide on a set of hydrogel recipe components. Recipe design needs are determined using an existing bibliometric analysis of a hydrogel subfield, and available options are sourced from literature reviews, then assessed based on properties discussed in the literature. Candidates for the crosslinking initiation mechanism, the monomer system, and the crosslinking control method are evaluated separately and sequentially. Recipe permutations are possible as multiple choices are scored. The resultant recipe is a photoinitiated (LAP; irradiated at 380.5nm), thiol-ene (TMPMP-Maleimide), light-patterned (maskless PWM-DLP) hydrogel that swells and bends in response to water due to osmolyte (D-Sorbitol) diffusion. This novel formulation is not currently present in the literature; however, it does not exhibit any chemical or practical incompatibilities. A range of component concentrations, possible failure scenarios, and recommended fixes are provided for initial testing.</abstract>

    <title language="eng">Design and Validation of a Bio-Inspired Tendon-Driven Continuum Manipulator</title>
    <abstract language="eng">This thesis develops bio-inspired, multi-segment tendon-driven continuum manipulator through a structured, iterative design process. Combining piecewise constant-curvature modeling, for design validation, with hybrid soft-rigid joint fabrication, three prototypes explore trade-offs among anatomical scale, actuation efficiency, and structural compliance. Novel, internal, soft-rigid components, buckling-mitigation features and internally routed tendons are integrated and evaluated under a common experimental frame work. Demonstrations include single-finger grasps and coordinated bimanual object handling, confirming the manipulator’s viability for humanoid end-effector tasks. The final design produced a tip-load of ≈ 17N for a pinching grasp and ≈ 12N in a power grasp, with 4 degrees of freedom and a maximum bending angle of 209°. Future work will focus on closed-loop control, dynamic interaction testing, and scaling to multi-digit hands.</abstract>

    <title language="eng">Origami Applications in Engineering</title>
    <abstract language="eng">This thesis explores how origami-inspired modular structures—specifically uniformly thick, load-carrying designs—can be prototyped using accessible 3D printing work flows. We focus on translating geometric folding principles into real materials and hinges suitable for repeated deployment by designing printable panels and connectors, and by validating performance with a bar-and-hinge simulation approach.&#13;
Physical prototypes are fabricated and tested for packing ratio, deployment re&#13;
peatability, and stiffness-to-mass. Results indicate that thick-panel origami can&#13;
be produced with consumer 3D printers while retaining compact storage, rapid deployment, and promising structural behavior. The work outlines a practical path toward portable, reusable, and more sustainable engineering systems that minimize material use, support repair and reuse through modularity, and simplify logistics through high packing ratios.</abstract>

    <title language="eng">Application of Carbon Fiber and Advanced Composites in Restorative Dentistry: A Study in Material Efficiency, Manufacturing viability, Market Potential and Innovation.</title>
    <abstract language="eng">This work presents a multidisciplinary evaluation of Carbon Fibre Reinforced Polyether Ether Ketone (CF-PEEK) as a core material for hybrid dental crowns, combined with lithium disilicate (E-max) veneers.&#13;
The objective was to assess the mechanical, manufacturing, and economic feasibility of introducing CF-PEEK into restorative dentistry through an engineering-driven approach.&#13;
&#13;
A systematic literature review compared the elastic modulus, flexural strength, and density of CF-PEEK with conventional materials such as zirconia and porcelain-fused-to-metal.&#13;
Results show that CF-PEEK exhibits a modulus close to natural dentin and lower density, offering improved biomechanical compatibility and reduced stress transmission.&#13;
Additive manufacturing (3D printing) was identified as the most flexible and sustainable production method, minimising material waste and enabling customised crown fabrication.&#13;
&#13;
The study concludes that the CF-PEEK + E-max hybrid crown is mechanically viable and aligns with sustainability goals, though improvements in bonding, colour masking, and clinical validation remain necessary.&#13;
This approach demonstrates how industrial engineering tools including TRIZ, QFD, and KANO can effectively guide innovation in dental materials and workflows.</abstract>

    <title language="eng">Development and implementation of an adaptive control system for automizing and optimizing the performance of a rolling fluid (setur) hydro-turbine</title>
    <abstract language="eng">This thesis presents the design and implementation of an automated control system for a laboratory-scale SETUR (Sedlacek's Blade-less Rolling Fluid Turbine) hydro turbine test rig. The goal was to enable precise and repeatable experiments by automating the regulation of the turbine’s water level and data acquisition process. The developed system integrates multiple sensors, including discrete liquid level sensors, pressure transducers, and a flow meter, interfaced with an Arduino-based controller.&#13;
A PID-based control algorithm with gain scheduling was designed to adapt to the nonlinear flow dynamics across different operating regimes of the turbine. The control loop operates at a 0.5 s sampling rate and employs layered signal filtering and calibration routines to compensate for sensor noise, offset, and scaling errors. The complete hardware setup includes signal conditioning circuits for analog sensors, digital communication for actuator control, and real-time data monitoring via serial output.&#13;
Experimental results demonstrate that the system achieves stable water-level regulation within approximately two minutes after pump activation and maintains steady-state operation without overshoot or sustained valve saturation. The overall measurement uncertainties were quantified as ±3.06 % FS for pressure and ±5.2 % FS for flow, meeting the predefined accuracy requirement of ≤ 5 % FS.&#13;
The developed automation platform provides a reliable foundation for further research on the SETUR turbine, including efficiency characterization, advanced control development, and future integration of IoT-based supervisory monitoring and data analysis tools.</abstract>

    <title language="eng">Applying Different Path Planning Algorithms to a Mini Mars Rover for an Uncharted Maze</title>
    <abstract language="eng">This thesis explores how an already built Mini Mars Rover can autonomously navigate an uncharted maze, first by mapping it and then by applying different pathfinding strategies.&#13;
The Mini Mars Rover uses IR sensors for wall detection, encoder-based odometry for tracking movement, an IMU for heading corrections, for input for more accurate localization.&#13;
The strategy combines exploration techniques with practical path execution on real hardware, focusing on the challenges that come up when algorithms meet the physical world.&#13;
Exploration applied by using a combination of Breadth-First Search (BFS) with the Travelling Salesman Problem (TSP) approach, as well as a Partially Observable Markov Decision Process (POMDP) strategy. Although both methods showed promising results in simulation, in hardware testing same results were not gathered.&#13;
For the path planning, three pathfinding algorithms Flood Fill, Dijkstra’s, and A* are implemented and compared. The results of those algorithms and the strategy to adopt them into the robot is implemented.&#13;
The project demonstrates a possibility of adaptation of those algorithms and their feasibility.&#13;
The Mini MarsRover serves as a solid base for further development and improvements.</abstract>

    <title language="eng">Development, Controller Design and Validation of a Torque Vectoring System for an All-Wheel Drive Electric Go-Kart</title>
    <abstract language="eng">This thesis investigates the design and simulation-based evaluation of a yaw-rate control system using torque vectoring for an all-wheel-drive electric go-kart with independently driven wheels. The work is conducted within a purely model-based framework, employing MATLAB and Simulink to replicate the vehicle dynamics and control interactions in a controlled virtual environment.&#13;
Torque vectoring describes the distribution of drive torque between individual wheels to influence the yaw moment of the vehicle. This enables targeted improvements in stability, responsiveness, and cornering performance beyond what is achievable with steering input alone. In this study, yaw rate is selected as the primary control variable. A reference yaw rate is derived from the linear bicycle model, and the control objective is to minimize the error between the reference and the simulated actual yaw rate by applying corrective yaw moments through differential torque allocation.&#13;
A Proportional-Integral-Derivative (PID) controller is implemented to track the reference yaw rate. Gain tuning is performed using MATLAB’s PID Tuner, leveraging the system transfer function extracted from the simulation model. The complete control system is integrated into a modular Simulink model of the go-kart, which incorporates the 2-DOF bicycle model for lateral and yaw dynamics, as well as subsystems for maneuver generation and torque vectoring logic.&#13;
Controller performance is assessed through standard vehicle dynamics test maneuvers, including ramp steer, step steer, and double lane change. For each maneuver, simulations are performed both with and without torque vectoring, allowing quantitative comparison of yaw rate tracking accuracy, stability, and trajectory.&#13;
The results demonstrate that torque vectoring substantially improves yaw rate tracking and reduces the understeer tendency of the simulated vehicle, particularly during transient maneuvers. Even in a simplified small-scale vehicle model, the benefits of active yaw moment control are evident, underscoring the relevance of torque vectoring for enhancing dynamic performance in electric vehicles with independent wheel actuation. The modular simulation framework developed in this work also provides a foundation for future experimental validation on the physical research platform as well as further developments on the simulation model.</abstract>

    <title language="eng">Design, Development, and Testing of a Vision-Based Calibration System for Liquid Handling Robot</title>
    <abstract language="eng">This thesis presents the development of a vision-based calibration routine for an open-source liquid handling system, addressing the challenge of integrating reliable labware detection into an existing robotic platform with minimal hardware redesign. The study adopts an experimental, prototype-driven approach, evaluating multiple proof-of-concept configurations before selecting a top-mounted camera solution as the most viable. The implemented system employs OpenCV’s ArUco marker detection to locate labware, combined with a closed-loop tracking routine that iteratively aligns the camera’s principal point with the detected tag.&#13;
&#13;
Alternative approaches, such as rule-based detection with a side-mounted camera, provided valuable insight into system constraints including lighting sensitivity, and variability of labware. The chosen final setup demonstrated reliable calibration output in the form of labware position and orientation data, stored in .JSON format for integration into higher-level control software.&#13;
&#13;
The system proved capable of reliable marker-based calibration under controlled conditions. Furthermore, the results highlight both the strengths of the approach such as modularity and adaptability, and its limitations, particularly possible interference due to glare and relatively high setup time. Future work includes integrating object detection models, multi-camera systems for improved pose estimation, and extending the system towards real-time quality control in laboratory automation.</abstract>

    <title language="eng">Design and Development of an Automated Hyperspectral Imaging System for Plant Monitoring</title>
    <abstract language="eng">This thesis presents the design and construction of a prototype automated plant monitoring system that integrates hyperspectral imaging with a custom linear motion structure for greenhouse applications. Controlled by an Arduino-driven stepper motor, the system positions two hyperspectral cameras (covering visible–near-infrared and short-wave infrared ranges) and a stereo RGB camera along a linear guide to capture consistent and repeatable measurements. Calibration and data acquisition are managed by specialized software, enabling detection of early drought stress indicators such as pigment and water content changes before visible symptoms occur. Assembled and tested at Fraunhofer IGD, the prototype demonstrated reliable operation and consistent spectral data collection, providing a versatile foundation for future enhancements including automated workflows, machine learning–based analysis, and application in diverse agricultural settings.</abstract>

    <title language="eng">Development of a Key Performance Indicator Based Method for the Evaluation of Scan Strategies</title>
    <abstract language="eng">In the Laser powder bed fusion of metal, the laser beam melts and fuse the powder material to produce the part layer by layer. The scan strategy, which defines the pattern in which the laser moves on the powder bed, affects the mechanical properties, residual stress and quality of the parts. There are many scanning strategies and it is difficult to select the appropriate scanning strategy based on the required quality of the parts. In this thesis, key performance indicators related to scanning strategy are developed, based upon the literature, which can influence the quality of the parts like high density and low surface roughness. The developed KPI is used to evaluate the scanning strategy of printed parts and their results on surface roughness and density. The developed KPIs are integrated into custom software to collect the data for evaluation of scanning strategy. The correlation analysis is also performed to understand the relation between developed KPI and quality of the parts (surface roughness and density). The results shows that developed method can be used for evaluation of the scanning strategy but it needs to be further improved to get more accurate results.</abstract>

    <title language="eng">Characterization and Optimization of Process Parameters for Polycaprolactone-based Medical Scaffolds for a Magnetic Planar Drive-based 3D Printer</title>
    <abstract language="eng">This thesis investigates the optimization of process parameters for a Magnetic Planar Drive (MPD)-based 3D printer to fabricate Polycaprolactone (PCL) scaffolds for medical applications. The study aims to identify an optimal set of parameters that ensures high-dimensional accuracy while maintaining structural integrity. &#13;
A systematic experimental methodology was adopted, beginning with a full-factorial design to establish baseline parameters for printing temperature (170°C), printing speed (15 mm/s), and nozzle diameter (0.4 mm). A Box-Behnken Design (BBD) was employed to optimize critical parameters, specifically layer height, raster width, and mover levitation height. Analysis of Variance (ANOVA) identified layer height as the most dominant factor influencing dimensional accuracy (p &lt; 0.0001), while raster width and mover levitation had lesser effects.&#13;
The experimental validation of the optimization results revealed discrepancies between the numerically and empirically optimized parameter sets. Although the numerically optimized settings had a theoretically superior accuracy of 98.29%, their practical implementation led to structural failures, specifically the collapse of scaffold bridges. In contrast, the empirically optimized set (layer height: 0.2 mm, raster width: 0.45 mm, mover levitation height: 2.25 mm) consistently achieved a mean dimensional accuracy of 97.14% while maintaining stable printability.&#13;
The findings demonstrate the potential of MPD-based 3D printing for fabricating medical scaffolds and establishing a validated parameter set.</abstract>

    <title language="eng">Development of an arduino-controlled smart storage rack for component reels using MQTT and RS485 communication protocols</title>
    <abstract language="eng">This thesis represents the development of an innovative storage rack system designed to manage electronic component reels in the manufacturing environment efficiently. The system integrates multiple custom-designed PCBs equipped with many LEDs and sensors, each assigned to individual storage slots. Each storage slot is equipped with an LED and an infrared (IR) sensor. The sensors detect the presence of reels, while the LEDs provide visual guidance for storing or locating specific reels. To manage multiple sensors efficiently, a multiplexing method is used, allowing each Arduino Pro Mini to control up to 16 sensors with fewer pins. Multiple Arduino Pro Mini microcontrollers are deployed across different rack sections and communicate with a central master controller using the RS485 protocol. The master controller, based on an ESP32, connects to an MQTT broker to send and receive data from a storage management system. Users interact with the system through a web interface. When storing a reel, the user scans it into the online system, which then activates an LED to indicate the appropriate storage slot. When retrieving a reel, the system highlights its location via the corresponding LED. Sensors are used to confirm the presence or absence of reels within the slots ensuring accurate tracking of stored items in real time. The system is modular and scalable. In this thesis, the prototype demonstrates two levels of storage racks, each independently controlled and networked, validating the communication between multiple slave units and a master. Additionally, because of the different sizes of the reel, the design includes removable metal dividers between slots. When storing larger reels, dividers can be removed, and this change is also updated via MQTT to the online system. Power is supplied through a 5V, 30A power supply, ensuring stable operation of all electronic components. Overall, the results confirm that the system achieves reliable performance in both hardware and communication aspects, offering a practical and scalable solution for modern electronic component inventory management.</abstract>

    <title language="eng">Enhancing Plastic Degradation in Anaerobic Environments Using Biodigesters and qualitative quantitative analysis of biogas.</title>
    <abstract language="eng">Plastic pollution has been one of the significant challenges worldwide. We must develop innovations and recycling technologies with millions of tons of plastic produced annuallyThe amount of plastic waste in landfills, seas, and ecosystems has been seriously degrading the environment. New innovative ideas for reducing plastic waste, such as biodigesters and composting methods, are being utilized worldwide. This research examines options such as anaerobic biodigesters and composting techniques to improve plastic breakdown in controlled atmosphere conditions. In anaerobic digestion, digestion happens with the help of microbial organisms as they help break down the organic materials without oxygen and break down the plastics, simultaneously generating renewable energy resources. This research evaluates polymers developed through a blown film extrusion process at different temperatures, such as Polylactic Acid (PLA), Polybutylene Adipate Terephthalate (PBAT), Polyhydroxybutyrate-co-hydroxy hexanoate(PHBH), Bioplast GF 106, and Ecovio, under anaerobic conditions. The degradation results of polymers after a specific period were analyzed based on their mechanical and chemical properties. The research aimed to assess the rates and effectiveness of plastic decomposition in biodigesters compared to conventional degradation methods while also exploring the viability and scalability of biodigesters for managing plastic waste. This research provides information on the degradation of polymers under anaerobic conditions and how the temperature produced affects their degradation, along with methane production. This information could inform future strategies and regulations focused on decreasing plastic pollution and improving sustainability.</abstract>

    <title language="eng">Investigation of Anaerobic Digestion of Selected Bioplastics in Pilot-Scale Biodigesters</title>
    <abstract language="eng">Concerns have been raised about the end-of-life management of bioplastics as their demand increasing as a sustainable alternative to conventional plastics. The fate of bioplastic waste, especially packaging waste, remains largely unexplored in existing waste management systems. Anaerobic digestion (AD) is considered as a viable end-of-life option for bioplastics, however, current research has been primarily limited to lab-scale studies. This study investigated the anaerobic digestion of film samples made from Bioplast 106, PBAT, PLA and Ecovio (PLA/PBAT blend) under mesophilic and thermophilic conditions in pilot-scale biodigesters. The results of 90-day thermophilic AD demonstrated that PLA and Ecovio exhibited significant biodegradation of 36% and 50% by dry mass loss, respectively, while Bioplast 106 exhibited moderate biodegradation of 22.22%. The collective methane yield from these three bioplastics was 322.86 mL CH4/g VS, indicating their potential for biogas production. SEM and FT-IR analyses confirmed structural degradation of Bioplast 106, PLA, and Ecovio, while no degradation was observed for PBAT. PBAT showed high resistance to AD in pure and blended form (Bioplast 106, Ecovio). Bioplast 106 exhibited diverse degradation patterns, influenced by feedstock type, digester temperature, and processing conditions. This study might serves as valuable reference for assessing the anaerobic biodegradability of Bioplast 106 in pilot-scale biodigesters. This study further highlights the necessity of optimization of pilot-scale AD conditions to enhance the anaerobic biodegradability of slow-degrading bioplastics.</abstract>

    <title language="eng">Using the U-Net Model for Steel Microstructure Identification and Analysis</title>
    <abstract language="eng">This thesis presents the development and training of a U-Net- a convolutional neural network (CNN) model for the segmentation and classification of 4 microstructural phases in C45 steel: retained austenite, martensite, pearlite, and ferrite. It also features the steps taken to prepare the metallographic samples. The U-Net was designed and developed for biomedical microscopy&#13;
imaging but has a wide array of uses for semantic segmentation in other fields as well. Utilizing Nital-etched microscopy images, the network was trained to identify and differentiate between these microstructures, which is critical for determining the mechanical properties of the steel.&#13;
The dataset is comprised of a set of 35 grayscale images, and its corresponding labels/masks annotated with 4 colours for the various phases. Moreover, this thesis is an attempt at using deep learning to segregate retained austenite from martensite through visual LOM methods, as opposed to EBSD and XRD which are the widely used methods for identifying and quantifying retained austenite in a sample. The trained network demonstrated reasonable performance in segmenting the microstructural components. This research highlights the potential of deep learning approaches in materials science, particularly for automating the analysis of metallographic images, contributing to more efficient and precise material characterization.</abstract>

    <title language="eng">Analysis of Health Literacy among Young Adults</title>
    <abstract language="eng">This study investigates several key questions related to health literacy, text difficulty, and AI-generated content. Our research explores whether there is a statistical significance in the perceived difficulty of texts based on their authorship (human-translated to layman language, AI-translated, and original excerpts from a medical book), the correlation between participants' evaluations of text difficulty and quantitative analysis of these texts using JASNOPIS, and the relationship between health literacy levels and the ability to recognise AI-generated work. Additionally, the study examines the impact of exposure to AI-made writing on recognising AI-generated content and the relationship between health literacy levels and perceived text difficulty.&#13;
A cross-sectional survey was conducted with 94 participants, collecting data through online questionnaires between September 19, 2024, and October 9, 2024. Key findings include significant correlations between average perceived difficulty and several JASNOPIS variables. The study also highlights the lack of a significant relationship between exposure to AI-made writing and the ability to recognise AI-generated work. However, the findings indicate that individuals who scored higher on health literacy tests perceived the texts to be easier.&#13;
The implications of this research emphasise the importance of enhancing health-related and educational materials using plain language principles to improve accessibility and comprehension. Future studies should consider using more objective measures to avoid the influence of personal biases.</abstract>

    <title language="eng">The Role of Demographic Factors in Journalistic Trust Post-COVID-19: A Questionnaire Analysis</title>
    <abstract language="eng">The COVID-19 pandemic has undoubtedly reshaped many aspects of society worldwide, including public trust in science and journalism. This thesis investigates both reasons and demographic factors (e.g., age, education, political orientation, etc.) influencing these trust dynamics as a result of the pandemic. Two countries with distinct cultural and socioeconomical differences are considered: Germany and Nigeria.&#13;
&#13;
Through a mixed-methods analysis of a pre-tested, pre-registered, cross-sectional online survey conducted in Germany and Nigeria in February 2023, several patterns are identified. The COVID-19 pandemic drove an increase in trust in science in both countries, while a marginal increase in trust in journalism was observed in Nigeria and a substantial decrease in Germany; this decline affected all demographics in the latter country.&#13;
&#13;
The thesis concludes with an outlook on further research. This includes conducting follow-up interviews to additionally explore reasons behind reported trust changes as well as the relationship between demographic factors and trust levels; performing a larger-scale survey with the aim of statistical significance and generalisability is further recommended.</abstract>

    <title language="eng">Selection of Global Standardization Samples for Optical Emission Spectrometry from Practical and Materials Science Perspectives</title>
    <abstract language="eng">The focus of this thesis is to address the task of alloy selection for Optical Emission Spectrometry (OES) applications. The main goal is to develop standardised samples for SPECTRO OES devices that can be utilised during routine analysis in automatic processes. The selection criteria include machinability, signal performance, and homogeneity. To achieve these goals, a set of practical tests were carried out. The initial research involves using the existing SPECTRO sample library to identify suitable alloys for standardised production in large batches. In the end, a database is suggested with existing alloys as possible candidates for future production. The chosen alloy must generate signals within specified wavelength ranges and exhibit machinability for post-analysis processing. The thesis introduces a unique approach to assessing machinability using chip analysis, emphasising the role of chip characteristics in understanding the material's suitability for machining. The study found that the E/3 sample, especially among samples with zirconium, demonstrated exceptional machinability. Moreover, the research delves into the importance of power consumption measurements during milling as an informative parameter for machining requirements. The study examines the chemical composition necessary to produce consistent and robust signals across the spectrum, with a particular focus on elements like zirconium, nickel, iron, copper, titanium, and manganese, but also phase diagrams to understand the homogeneity of aluminium alloying elements. Sample 518X905 is highlighted for its role in enhancing emission lines. In conclusion, the thesis proposes an alloy composition that blends aluminium with various alloying elements to meet specific research requirements. Copper, iron, zinc, silicon, nickel, zirconium, chromium, and vanadium provide flexibility for crafting tailored samples. Existing primary alloying elements, including those with copper, zinc, and silicon, can be considered. However, zirconium with a concentration of 0.6% to 1% is pivotal in the proposed alloy recipe.</abstract>

    <title language="eng">An Elaborated Environmental Life Cycle Assessment on Renewable Energy in Germany</title>
    <abstract language="eng">Life Cycle Assessment is a method of assessing the environmental impacts throughout the life cycle of a product. It was standardized by ISO to aid comparison of different studies employing the method of Life Cycle Assessment. The standard contains the phases: Goal and Scope, Life Cycle Inventory, Life Cycle Impact Assessment, and Interpretation. A Life Cycle Assessment is conducted on renewable energies in Germany, namely Wind Energy, Solar Energy, Bioenergy, and Green Hydrogen Energy. The data collection phase of the life cycle inventory was performed under several assumptions and limitations which extend to the results. It is established through the results of the study that Green Hydrogen energy holds the greatest environmental impacts out of the four energies. This impact is justified as Green Hydrogen is an energy carrier, rather than a producer. The impacts of Wind Energy, Solar Energy, and Bioenergy are compared in the absence of Green Hydrogen Energy, as they are all energy producers. It is found that the overall environmental impacts of Bioenergy are the greatest of the three, while Wind Energy has the lowest impacts. Solar Energy had greater impacts than Bioenergy in certain impact categories. Comparison of this study with previous Life Cycle Assessments reveals some similarities and differences. Contrasting this study to the German Sustainable Development Strategy shows that the strategy as well as the current trends are supported by the results of this study, but can be improved in certain aspects.</abstract>

    <title language="eng">Determination of Total Carbon with Infrared  Absorption Method After Combustion in an Induction  Furnace for Ferro-Chromium Alloys</title>
    <abstract language="eng">In this thesis, an evaluation of the determination of the total carbon in ferroalloys, with a focus on ferrochromium, via infrared absorption after combustion in an induction furnace is conducted. The experiments were performed over a period of 4 months with the goal of setting a robust calibration for carbon detection in ferroalloys. Ferrochromium ranging from 0,01 % to 9,03 % carbon was used as a reference material for the calibration. It was tested by using independent certified reference materials of ferrochromium but also additional ferroalloys like ferro-manganese, -silicon, - niobium, -titanium and -vanadium for the validation process. The statistical calculations were performed using the NORDTEST standards to ensure reliable results. Additionally, the drift of the machine and the detection and quantification limits were investigated. It revealed that the drift had to be applied daily, and that the quantification limit of the detector in the CS-analyzer is around 0,012 % carbon. As a result of the statistical calculations, it appeared that the measurement uncertainty is carbon percentage dependent. This led to the creation of a function that can estimate the measurement uncertainty dependent on the carbon percentage for future analysis.&#13;
Subsequential testing proved the emission of reasonable results for all tested materials, validating that the set calibration can be applied to those materials without further refinement of the calibration method.</abstract>

    <title language="eng">ESG Reporting as a Sustainability Performance Measurement in Educational Institutions</title>
    <abstract language="eng">The concept of Environmental, Social and Governance (ESG) reporting is not a new thing. It initially comes from the concept of non-financial reporting and corporate sustainability reporting. Over time this concept emerged as an essential tool in sustainability performance assessment.&#13;
 &#13;
This research dives into the dimensions of Environmental, Social and Governance (ESG) reporting as a pivoting tool for evaluating sustainability performance in educational institutions. The study conducts a case study of the campus Hochschule Rhein-Waal sustainability intending to gain insights into the institution's performance concerning sustainability metrics. The research explores the integration of 17 Sustainable Development Goals (SDGs), 10 principles United Nations Global Compact (UNGC), along with the alignment of variables with the Global Reporting Initiative (GRI) into a tailored ESG framework for Higher Education Institutions (HEIs).&#13;
&#13;
In addition to the in-depth examination of campus HSRW sustainability with Environmental, Social and Governance (ESG) dimensions, assessments of insights on on-campus areas of improvement about the indicators are highlighted. In summary, this study aimed to provide useful information for academic institutions seeking to enhance their sustainability initiatives as sustainability becomes an essential component of higher education.</abstract>

    <title language="eng">Documentation and Further Development of a Digital Factory Simulation Game</title>
    <abstract language="eng">The fusion of digital technologies in manufacturing and production initiates the progress in Industry 4.0. This paper explores the literature review on Industry 4.0 and Internet of Things (IoT). The literature review explores the historical background and components of Industry 4.0. It also highlights the elements of IoT and the concept of a digital factory. In the context of digitalization, the integration of a digital factory simulation game is relevant. The&#13;
game provides a comprehensive view of manufacturing and production in a lab environment.&#13;
This paper addresses the gameplay concept, comparing the manual and digitalized phases.&#13;
It highlights how the game reflects a virtual factory environment by integrating with IoT devices. Several industries implement technological elements in today’s dynamic industrial landscape for smooth and efficient productivity. By presenting an overview of the digital elements used in the game and the industries, this paper assists in comparing the industrial elements to the game. The framework involves an analysis of technologies commonly used&#13;
in the industries to establish connectivity of the game. Thus, the primary concern of this paper comprises the evaluation of the industrial elements of the game through a feasibility study to design a roadmap for further development of the game.&#13;
Supplementary materials and supporting documents can be found in the appendices of the thesis, expanding the approach of the game.</abstract>

    <title language="eng">Development of an Agrivoltaic Plant</title>
    <abstract language="eng">The present paper deals with developing two Agrivoltaics (Agri-PV) plants in Kleve, Germany, to study their feasibility and analyze the interaction between cattle farming and solar photovoltaic power generation. The study area will be used as pasture to feed the cows, which will allow evaluation of the economic and technical feasibility of this combination in an area called the "test area" and then to perform the second installation with a larger area called the "potential area." The main results include the decisions taken for the plant's design, the efficiency and performance of the Agri-PV system, the economic results obtained through simulations in PV*SOL software, and the use of plans developed in AutoCAD.&#13;
&#13;
The objective of the report is the correct implementation of the Agri-PV system in both the test area and the potential area. It has been demonstrated that integrating solar energy in agricultural areas offers a favorable economic projection, with adequate returns and positive cash flows. This implementation represents an opportunity to diversify income in the farm sector by generating energy for export to the power grid.&#13;
&#13;
The conclusions highlight the feasibility of the Agri-PV model and its potential as an effective solution for renewable energy generation in agricultural areas. Further research is suggested to evaluate the impact on agricultural productivity and the interaction of the cows with the panels and to conduct long-term economic and financial studies to ensure the system's sustainability.</abstract>

    <title language="eng">Simulation of the temporal behavior of logical execution time in combination with classical tasks in an AUTOSAR Classic multi-core computer system using the tool ChronSim.</title>
    <abstract language="eng">Modern automotive systems have transitioned to distributed architectures, necessitating their embedded real-time software to be deterministic to ensure that they operate properly. To achieve this deterministic behavior, the Bounded Execution Time (BET) model, in combination with the Logical Execution Time (LET) paradigm, is applied on some software. This scheduling method is tested for applicability on new software projects at the early-concept phase of their development. This research is done by performing scheduling simulation with the tool chronSIM by INCHRON.&#13;
However, chronSIM lacks basic model object to represent LET tasks. This thesis addresses this deficiency by presenting a model for LET within an AUTOSAR classic multi-core computer system, all within the chronSIM tool. The research elaborates on creating a model for LET tasks using the basic model objects available in chronSIM. Furthermore, an existing scripted modeling toolchain, used by Vitesco Technologies engineers for software project modeling and simulation, is upgraded to model LET tasks and introduces new configuration options which can be used to setup a couple LET scheduling scenarios. The thesis also includes simulation of several projects, with in-depth analysis of their simulation results.&#13;
The primary objective of this thesis is to advance the simulation process of automotive software to analyze the applicability of a range of scheduling configurations.</abstract>

    <title language="eng">Controller Design, Implementation, and Comparison on a Ball-on-Wheel Test Rig</title>
    <abstract language="eng">This thesis project considers the control of the ball-on-wheel (BOW) system with proportional-integral-derivative (PID) and full-state feedback controllers. The BOW test rig consists of the wheel that is actuated by the electric motor, motor encoder, and laser sensor. The desired outcome is to stabilize the ball around the equilibrium point on top of the wheel. By employing common control design techniques and establishing appropriate Simulink models the controllers for the BOW system were implemented. The dSpace software was used to capture the performance of the controllers, while MATLAB was used for analysis. However, various issues arose during the design and commissioning processes, preventing the state-space controller to achieve the desired outcome. As a result, a performance comparison was conducted based on Simulink models, as the state-space controller design failed to perform adequately on the BOW test rig. These issues were thoroughly explained within the thesis and the implications were summarized in the conclusion.</abstract>

    <title language="eng">The design and build of a robust syringe pump for extension/contraction of artificial muscles</title>
    <abstract language="eng">Field of bionics has been a great source of inspiration for mankind; and even the recent scientific discoveries of the past decades, has increased importance of this field in the modern life.&#13;
In this growing trend, more and more scientists are trying to surf over the waves of bio-inspired solutions, but the fundamental differences between nature’s point of view and man-kind, on managing the resources and solving problems, has made the traditional equipment’s of scientist, obsolete; especially when it come to actuation methods.&#13;
Since the traditional device and component are not suitable for cutting edge fields, such as bio-inspired robotic, artificial muscles, soft robotic and so on; this thesis has offered an especially designed syringe pump, to fulfill this need.&#13;
Starting from the basic constraints and expectations for such syringe pump, a morphological box has been shaped in this project; and along with having an eye over relatively similar products in the market, borders of “design function” has been drawn.&#13;
By considering the available equipment and tools for production of such device, the “design concept” of this thesis has been formed.&#13;
And finally, after days of manufacturing, the prototype of this concept has been brought to life.&#13;
In this syringe pump, a stepper motor (NEMA-17) is controlled by combination of computer, Arduino UNO and microstep driver DM542; by powering this stepper, a lead screw will be driven. Designing an aluminum structure and connecting a lead-nut to the lead-screw; linear displacement can be produced.&#13;
This linear displacement is responsible for movement of a tray, which is holding onto the end of syringe’s plunger; and by clamping the cylinder to the designed station of the thesis; with this configuration, desired static pressure can be produced by displacing the plunger.&#13;
Having this static pressure, is the key feature for simulating many different biomimetics projects, such as soft robotics and artificial muscles.&#13;
As the results, this thesis has achieve the high precision and resolution of “100 𝜇m” for each 5 steps of stepper motor, equivalent to 9° of rotation.&#13;
Furthermore, the prototype have easily and quickly delivered 300 mmHg (39.99Kpa), by using only a single 20ml syringe; and reached the highest speed of 750 rpm for the stepper motor.</abstract>

    <title language="eng">Estimating the State of Charge of Lithium-ion Batteries using Deep Learning for Electric Vehicle Applications</title>
    <abstract language="eng">Reliable and safe operation of Li-ion batteries in electric vehicles relies on an accurate estimation of their states, more specifically their state of charge (SOC), which is used for managing charging and discharging, for example. Deep learning is increasingly used for modeling complex systems, which generates more interest in battery state estimation.&#13;
The theoretical investigation of candidate neural networks for SOC estimation is preceded an experimental approach to evaluate the shortlisted neural networks performance. Publicly available testing datasets representing real driving cycles has been used to train the selected networks, taking into consideration different operating temperatures for the exact cycles. Testing the prediction capability of the models across a realistic range of operating conditions is the driving factor for including testing cycles with a temperature range of [0–40] °C in the training datasets. A demonstration of the full training cycle is conducted, along with the optimization problem of network parameters.&#13;
This work demonstrates the applicable neural network family used for training this kind of sequential data, followed by the shortlisting of two neural networks based on their performance using literature research. After selecting the networks, finer evaluation criteria is applied, including both their prediction capability and training requirements. The results show that both networks, long short-term memory (LSTM) and gate recurrent units (GRU), offer satisfactory prediction capability with mean absolute error (MAE) of (2.9%, 2.7%) respectively, when averaged across the tested temperatures. The GRU network on the other hand had significantly higher resource requirements and a more complex architecture. Finally, a more recent architecture is briefly discussed, borrowing the strength of a parallel application field. The scope of this work is to highlight both the capabilities and cost of training deep learning networks for SOC estimation.</abstract>

    <title language="eng">Development and Implementation of a Cascade Torque Controller for a Motor Test Rig</title>
    <abstract language="eng">Servo systems play an important role in the field of automation thanks to their great actuation capability. The majority of industrial servos rely on feeding back armature current for torque control based on the torque-current linear relationship. However, system non-linearity like input delay or external disturbances can make the built-in control mode no longer yields acceptable torque response. This thesis deals with two servo systems in coupling with a torque transducer on a motor test rig as part of a Hardware-in-the-Loop setup. The motor torque step response exhibits a large steady-state error and significant overshoot behavior. This thesis work takes two different approaches to develop a cascade controller that gives desired torque performance. One method is the popular PID control logic and the second is the modern State-Feedback Control architecture using Pole Placement technique. The controller design process is carried out based on an estimated plant model obtained from grey box system identification with experiment data. The designed cascade controllers are implemented and tested on the HIL system with different use cases and yield improved torque transient response with near-zero steady-state error and less than 5% overshoot under step input in both stationary and rotating conditions. The outer loop controllers are also able to reject intermittent disturbance and track low-frequency input better than the original system. The developed cascade control systems are characterized by high stability margins but limited bandwidth, hence not being able to compensate for the dynamic disturbance of frequency larger than 2.5 Hz. Overall, there are not many differences between the performance of the two control laws, as both can satisfy the system performance requirements.</abstract>

    <title language="eng">Comparison of wheel and rubber track drives for tractors regarding masses, mass inertias, energy demands and tractor mechanics</title>
    <abstract language="eng">Soil compaction is a major concern in agriculture. As farming machinery develops to be larger and heavier, the risk of soil compaction increases. Tractors with rubber tracks have been developed to increase the contact area with soil in order to reduce the risk of soil compaction as well as to increase tractive performance. However, tractors with rubber tracks have increased mass due to the track components. Therefore, the combined effect of rubber tracks was investigated.&#13;
Comparison of tyres and rubber tracks for tractors on mass, mass inertia, tractor mechanics, energy demand, and soil compaction were investigated. Configurations of tractors consisting of combinations of tyres and interchangeable rubber tracks are evaluated in calculations and in simulation tool Terranimo. Simplified rubber track models were built in order to investigate effect of inertia from the rotational components on energy demand. A theoretical scenario was constructed to calculate the energy demand for the predefined workload. &#13;
Experimental data in past research showed that the superior tractive performance of rubber track is more apparent in looser soil. In the energy demand calculation part of the thesis the tracked configurations resulted in a higher energy demand. The tracked configurations also showed effect on reducing risk of soil compaction in the same defined scenario. However, the increased energy demand, hence higher fuel consumption and energy efficiency is a downside of the tracked configurations, and the selection between tyre and rubber track should depend on the situation.</abstract>

    <title language="eng">Implementation, execution, and analysis of efficiency measurements to be used in the calculation of CO₂ emissions and fuel consumption of heavy-duty vehicles as per Commission Regulation (EU) 2017/2400</title>
    <abstract language="eng">Quick and reliable transport of goods within the European Union is possible, in part, due to the use of heavy-duty vehicles. Whether long-haul routes, or local and urban deliveries, heavy-duty vehicles are crucial for a large part of EU’s economic activity and the number of these vehicles on the road increases every year. However, they also are main contributors to the total greenhouse gas emissions of the road transport sector and play an important role in the total emissions of the European Union. Therefore, it is of great economic and environmental importance to closely monitor emissions and fuel efficiency of heavy-duty vehicles currently on the road and market, forcing manufacturers to reduce emissions from their vehicles and develop more energy-efficient technologies. For this purpose, the European Commission developed the VECTO simulation tool, reducing costs and time necessary for the approval process and monitoring of new vehicles in the EU.&#13;
 &#13;
While generic values related to the CO₂ emissions and fuel efficiency characteristics of most components of heavy-duty vehicles are provided by the European Commission to use in VECTO simulations, accurate results require actual component testing. With no VECTO specific testing offered by vehicle testing specialists, this thesis aims to conduct an analysis of Commission Regulation (EU) 2017/2400, guideline for the use of VECTO, to identify requirements, develop and implement testing procedures in experimental tests, and validate results to ensure that the requirements of the regulation are met.</abstract>

    <title language="eng">ACC 3000: Autonomous Cobblestone Cleaning-robot</title>
    <abstract language="eng">Our goal is to create a user-friendly and safe autonomous driving cleaning robot for large-scale cobblestone areas or parking lots. Primary target group of our product is the semi-professional part of the autonomous cleaning robot market. The ACC 3000 robot is designed with two motions and one 360-degree environment IR sensor and a recharge station with an inbuilt Wi-Fi device to monitor the robot. The robot can drive anywhere if no obstacles are detected. The ground is flat, the inclination does not exceed 5 degrees and the Wi-Fi connection is not lost. When switched on, the controller inside gets continuously updated on the health parameter, e.g., battery status and obstacle detection by the help of the sensors. The robot is controlled and can be monitored by an app on a smart phone. Simple commands, such as ON/OFF switch, route mapping and two different rotational speeds of the wire brushes are possible to set up. For example, setting up the system for higher rotational speeds of the wire brushes ensures to remove even persistent plant or moss infestation in between gaps of the ground surface. Our competitive advantage is that our cleaning robot is made of durable and cost-efficient materials and will save household costs as a long-term investment by removal of labour cost of expensive workers. There are no other autonomous cleaning robots at this price available that match our design and usability, which makes our product unique in the market. We will start production and sales in Germany with plans to later expand into the European, North American, and Asia-Pacific region.&#13;
Our product pitch, design concept, and features are presented in an audio-visual format and is awarded the Science Communication ‘Gold Leaf Prize’ for an outstanding online video presentation in the category of ‘Audience Choice’ on January 18th, 2022.</abstract>

    <title language="eng">Feasibility check, design and dimensioning of a scrounger magnet coupling to a Siemens-E-Highway-truck</title>
    <abstract language="eng">Among other factors, electric vehicles (EVs) were developed with the intention of mitigating the transportation sector’s impact on the environment and the depletion of fossil fuels. While various methods exist to charge electric vehicles (EVs) or extend their driving ranges, each have their benefits and drawbacks. As such, a method to accomplish the latter, i.e., to extend the driving range of an EV – and more specifically, a battery electric vehicle (BEV) – is proposed, which entails magnetically coupling to an electric truck (ET) ahead. This is enabled by a front-mounted system, comprised of a magnetic circuit (MC) and a linear axis (LA), which acts as a drawbridge to extend the MC ahead of the vehicle to a steel plate located at the rear of the ET. By utilising an array of permanent magnets (PMs) and a solenoid within a pot ferrite core (PFC) structure, the proposed system is able to easily generate a coupling force of around 6400 𝑁, which is sufficient to maintain the magnetic couple to the ET ahead, even under slight deceleration of the BEV of 2 𝑚 ⁄ s^2, as it recuperates energy via regenerative braking. With the proposed system, a power gain of 30.24 𝑘𝑊 is achievable in this manner, which allows for a significant improvement to the driving range of BEVs, as well as providing similar benefits as those offered by dynamic charging systems, namely, the convenience, and is thus regarded as a feasible solution, with regard to its performance.</abstract>

    <title language="eng">Evaluation of Solidworks on how to integrate part preparation for Additive Manufacturing in the CAD modeling process</title>
    <abstract language="eng">Solidworks is a CAD software that facilitates the construction of 3D models and drawings to enable production. These systems are usually designed to be used in conjunction with Subtractive Manufacturing (SM) and forming processes. This is due to the enormous portion of world-wide production in which these two processes are used. Because of this, design guidelines are customarily based on the abilities and constraints of conventional manufacturing processes. Additive Manufacturing (AM) replaces these with a new set of advantages and limitations that should be considered to assist in the design of parts. Design for Additive Manufacturing (DfAM) represents a methodology which closely resembles Design for Assembly (DFA) and Design for Manufacturing (DFM), as far as reducing component count and allow for easier manufacturing. The aim of this research is to establish DfAM criteria and to evaluate the core Solidworks software in its ability to support design using these criteria. DfAM criteria is sub-divided into two categories. Product DfAM criteria are those derived from the advantages offered by AM technology, while Process DfAM are those determined by the limitations of the AM technique used. Three example models, each addressing multiple criteria, are created in Solidworks and optimized for printing. Through this process, helpful features in the software are identified and analyzed. Embodiment of these examples by means of Fused Deposition Modeling (FDM) validates these features in an exemplary way and explores the integration of AM design practices in Solidworks. The results of this evaluation will allow further research into CAD support for AM, specifically with respect to Product DfAM.</abstract>

    <title language="eng">COBBRO (Robotic Cobble Cleaner)</title>
    <abstract language="eng">In this report, the detailed description and design of the robotic cobble cleaner, which we plan to construct and introduce to the market. The main function of our robotic cobble cleaner is to remove plant growth from the cracks between cobbles or tiles. This will be made possible by the Nylon brush roller component installed at the base of this machine. Our machine’s secondary function is to collect the plant material residue/debris after the cleaning has been done. This will be facilitated by a vacuum that will also be located at the base of the body of the robot. Regarding power supply, our robot will be powered by rechargeable batteries in its body and a charging station will be installed in the area of operation. Perimeter wires will also be laid down around the area where the robot will operate for navigation and self-charging purposes. The robot will have two ON/OFF switches. The main one is to turn it on/off and activate every function exclusive of the vacuum system and the other is to turn on the vacuum system. The decision to isolate the vacuum system from the rest of the robot was made due to sustainability and efficiency reasons. Our robot will be able to move on four wheels driven by two motors in the front, that is, front-wheel drive (FWD). Our robot will also engage the functionality offered by sensors for easy navigation and smooth operation in fulfilling its goal of autonomy. As a team, we opted to prioritize the small-scale commercial sector as our main market due to primarily financial and usability factors. After doing market research, we discovered that this market needed such a product the most and had sufficient area and capital to utilize it adequately. Regardless, our product will still be open to the other sectors in the economy, such as large-scale organisations and domestic consumers with regards to functionality and performance. Our product pitch, design concept, and features are presented in an audio-visual format and is awarded the Science Communication ‘Silver Leaf Prize’ for an outstanding online video presentation in the category of ‘Audience Choice’ on January 18th, 2022.</abstract>

    <title language="eng">EZClean-Bot</title>
    <abstract language="eng">Cobblestone cleaner tools are very demanding in most residences, poolsides, gardens, and even public places like sidewalks, bicycle lanes, etc. Although many companies have tried to make good handheld tools, we want to upgrade them into an autonomous cobble cleaning robot. The robot is called EZClean-Bot. Our slogan “Always on-Always clean-Always relax” means that when you set it on for the first time, you don’t have to look after it again because it has an automatic “Return to Home” feature that allows the robot to automatically charge itself when it has done its job. The robot will also be provided continuous power from the sunlight using a Solar Panel attached on top of it. The robot will be controlled by user-friendly buttons, and it is integrated with a self-mapping system, so it will clean the whole area thoroughly without bumping and crashing into objects or humans/animals. The robot can start itself using a pre-set timer/schedule. This EZClean-Bot is integrated with strong and durable steel brushes which are attached in vertical and horizontal directions, so it can clean not only the cobble/pavement but also the grass, dust, soil, and dirt between the cobble. The brushes will be attached with a small but high torque motor and can spin up to 10000 RPM depending on the surface. The robot has 2 big motorized driving wheels at the rear and 2 caster wheels for free movement. The whole system will be energized by two Li-Ion 12V and 5V batteries and a solar panel to increase its running time. There will also be some RGB LED light strips around the robot, so it can tell some information by seeing the different light colors. In addition, the robot is included with a high-capacity container to store the dust, soil, grass, etc. so you don’t have to sweep it by yourself again. The focus of our project will be a lightweight, portable, easy to maintain, energy-efficient, safe, and durable machine in which we have all our wiring, gear, motor, brush fully enclosed in a housing that protects it from water, wind, dust, and other extreme conditions. The cost of this product will be kept as low as possible in order to reach as many customers as we could. This robot will be a middle-end robot, so its target sale will be middle-range financial residence to a small company in Europe. Lastly, our product will be produced by four intelligent engineers from different majors and specialities. Our product pitch, design concept, and features are presented in an audio-visual format and is awarded the Science Communication ‘Bronze Leaf Prize’ for an outstanding online video presentation in the category of ‘Audience Choice’ on January 18th, 2022.</abstract>

    <title language="eng">Using MS Excel as solver in ansys workbench for the static and fatigue assessment in accordance with the FKM guideline</title>
    <abstract language="eng">The FKM guideline offers a structured and detailed framework for static and fatigue strength assessment for steel, aluminum, and cast iron components. This study aimed to investigate Microsoft Office Excel’s use of mechanical components’ static and fatigue strength verification for non-welded and welded components and its integration into Ansys Workbench. An FKM Excel tool was developed to calculate the assessment and tested against the FKM guideline example. A detailed comparison is made between the results of the FKM Excel tool and the FKM guideline example. Moreover, relevant stress and stress gradient values were obtained using Ansys Parametric Design Language (APDL). This investigation has revealed that the methodology is very efficient and faster. Furthermore, it makes it possible to use for proof strength. This research implies that there is a possibility of obtaining further automating processes in excel and Ansys Workbench.</abstract>

    <title language="eng">Development of Decision-making Model for Cost Optimization of Heat Exchanger on the Basis of Spreadsheet Programs</title>
    <abstract language="eng">The current advancements in the field of heat exchangers have expanded their range of applications in many industries. The most important factor while investing in the heat exchanger is sizing them for a particular application. The sizing of a shell and tube heat exchanger is always a challenge, often causing customers to invest in either an oversized or undersized heat exchanger. The purpose of this study is to solve the customer’s conundrum of investing in an appropriate size shell and tube heat exchanger. The objectives of this study were (a) to develop and implement a spreadsheet program for optimization of overall heat transfer coefficient of shell and tube heat exchanger, (b) to determine profitability analysis using the Net Present Value (NPV) method, (c) to analyse the price sensitivity using the Monte Carlo simulation. The iteration and optimization are based on Kern’s method. The user defines the process parameters such as the temperature of hot and cold streams, mass flow rates and fluid densities. The user also assumes the tube related properties. The final sizing of the shell side is determined along with Reynolds number and pressure losses on the shell and tube side. The pressure losses are then converted into the operating cost of the heat exchanger to determine NPV. The Monte Carlo simulation calculates 1000 different NPVs for a given scenario, thus facilitating the user’s crucial decision-making process. This study is probably a first instance to combine preliminary sizing of the shell and tube heat exchanger with price sensitivity analysis using the Monte Carlo method.</abstract>

    <title language="eng">Mathematical Modelling and Simulation of Catalyst Deactivation for the Continuous Thermo-Catalytic Decomposition of Methane</title>
    <abstract language="eng">A clean energy future based on a hydrogen economy has been proposed as a feasible alternative to the current combustion of fossil fuels to reduce CO2 and other greenhouse gas (GHG) emissions. However, hydrogen’s “clean” reputation is questionable due to its main production method of steam methane reforming (SMR), which produces large quantities of CO2 emissions. To abide by recent international regulations, the production of hydrogen needs an immediate transition to low-emission production methods. A promising solution is the thermo-catalytic decomposition of methane (TCMD), which thermally decomposes methane into hydrogen gas and solid carbon without any direct GHG emissions. The problem with this process is that the catalyst deactivates quickly and therefore must be replaced periodically for sustained hydrogen yields. This results in high catalyst turnover costs, which is the main bottleneck in the successful commercialisation of this process. By developing a simplified model using the most commercially viable parameters and linking the turnover costs with the deactivation of the catalyst, this study aimed to accelerate the adoption of the TCMD process by better enabling companies to analyse the feasibility of their potential low-emission TCMD solutions.&#13;
The most commercially viable solution featured the use of a fluidised bed reactor (FBR) for continuous operation with an iron-based catalyst due to their low-cost. Catalyst regeneration was found to be ineffective and the best method for mitigating catalyst deactivation was the optimisation of the process conditions. A simplified mathematical model was then constructed to enable this adjustment to maximise the production of hydrogen and minimise the turnover costs. This model was based on the ideal continuous stirred tank reactor but incorporated the fluidising behaviour through several variables including the development of the novel “Fluidisation Factor”. An optimisation ratio was also developed to quantify the simulation results and obtain the optimal conditions.&#13;
The results showed that the ideal conditions for this process was at the highest temperature before the catalyst starts to sinter (≈950ºC) and at the maximum pressure. The largest catalyst particle size of 150 𝜇m and the maximum amount of catalyst was found to allow for higher fluidisation velocities and to delay the deactivation time respectively. The inlet gas velocity and the catalyst activity limit were found to be highly dependent on the hydrogen production rate and therefore due to the conditions used in this study the optimum inlet gas velocity was 10% of the fluidisation velocity range (and composed of pure methane), whilst the optimum activity limit was at 22% activity. Lastly, a comparison of the heating method found that controlled heating was more suitable than constant heating due to the stable temperatures during deactivation, which prevent catalyst sintering. Comparing the optimised results from this study with the SMR production method found that the estimated catalyst turnover costs were 10¢/kg H2 and 18¢/kg H2 respectively. This demonstrates that the simplified model developed in this work can better enable companies to optimise and assess the feasibility of their proposed TCMD solutions and help transition their hydrogen production processes to cleaner alternatives.</abstract>

    <title language="eng">Solem Sunshade System</title>
    <abstract language="eng">This project completed the design of a portable and adaptive sunshade with automated sun movement compensation that emulates the sun’s natural path throughout the day. The design concept comprises of a closed loop feedback control system where light dependent resistors will be utilized as sensory components sending a microcontroller feedback signals containing information regarding the sun ́s light incident intensity. If the sun ́s light intensity decreases from a pre-specified intensity value, the microcontroller will send a signal to the relevant motor, adjusting the position of the sunshade. Two separate poles will control the movement of the sunshade. The lower pole is fixed and inserted inside a plate, rotating around its own axis dictated by a stepper motor, hence allowing rotation that follows the sun ́s natural azimuth angle. The upper pole is connected to the lower pole through a pin joint and will follow the sun ́s natural elevation angle dictated by a second stepper motor. Aluminium Alloy 6061 was chosen as our pole material due to its relatively high strength to weight ratio in addition to its durability, consequently achieving the desired portability and long lifespan of the product. Assessments conducted throughout this project proved the material’s ability to support the design structure and external loads subject to it. The structure will be foldable and be conveniently carried with a multifunction bag with simple installation steps to make the product user friendly. Initially the product will be tested in Germany and if met with success, will further expand to global markets located in coastal regions. The estimated total price for one unit is 914.99 euros. Our product pitch, design concept, and features are presented in an audio-visual format and is awarded the Science Communication ‘Gold Leaf Prize’ for an outstanding online video presentation on July 6th, 2021 in the category of ‘Audience Choice’.</abstract>

    <title language="eng">Meso-FE Modeling of Woven Fabric to Establish the Effects of Frictional Contact between Yarns</title>
    <abstract language="eng">Meso scale modeling has enormous impact on outcome of final composite material. For better understanding, immense research is carried, and state of the art literature review is presented in this thesis. For geometric modeling, a meso scale model of 2x2 Twill weave pattern is imported from TexGen software. Hypo elastic constitutive model is developed for material modeling of the yarn. Inter-yarn frictional behavior is thoroughly analyzed to explore the effects of different frictional models and contact types, to produce a cost-effective process on the outcome of final composite product. For an efficient investigation, a meso-finite elemental analysis is performed by replicating picture frame test virtually in Abaqus/Explicit solver. Suitable contact formulation and multiple friction models are used to input the frictional parameters on meso scale model. Finally, the simulation results are then validated by comparing between corresponding contact algorithms and frictional models.&#13;
&#13;
Objective of this thesis: The main objective is to determine the mechanical properties, concentrating on effects of friction of a Twill pattern weave by performing virtual simulations by replicating picture frame test (PFT). &#13;
&#13;
Solution process: Adequate literature research is accomplished for better understanding of concepts of simulation. In material modeling, hypo elastic material is defined for material properties is imported through VUMAT. Multiple frictional models, including VFRIC and VFRICTION are added to the model to define frictional behavior. In-plane shear deformations are calculated by numerical simulations virtually in Abaqus/Explicit solver and then results are examined. &#13;
&#13;
Key Results: Satisfied simulation results are obtained as expected. The frictional behavior between yarns is sensitive to contact algorithms and friction models, and quality of material modeling. The shear locking phenomenon is captured beyond 55-degree shear angle and observed that regardless of value of coefficient of friction yarns, the type of frictional models influences simulation results and force values.</abstract>

    <title language="eng">WATER-IT Smart Sprinkler</title>
    <abstract language="eng">Although smart irrigation systems are being extensively used for several years now, little effort have been dedicated towards sprinklers with wind compensation, resulting in many sprinklers in the market having less optimal design. Thus, this project aims to improve the existing sprinklers by including wind compensation. To reduce the effect of wind on the irrigation pattern, the sprinkler velocity and radius of throw need to be adapted to the wind’s velocity and direction. Our control valve box contains seven major components. Wind and rain sensors that will collect the weather conditions, an LCD where irrigation time will be displayed, additionally to a microcontroller communicating with a second MC at the sprinkler head box via Bluetooth and controlling an electrically actuated ball valve and solenoids connected to inline pressure reducers. These three latter components play an important role in supplying proper water conditions for the sprinkler by adjusting the pressure and water flow. The position of our sprinkler’s nozzle will be detected with a magnetometer and compared to wind direction. The servo motor will rotate the sprinkler and this latter will start irrigating in a 180° pattern for couple of minutes before rechecking again all the conditions. When the sprinkler nozzle is facing the wind the velocity of throw will be increased, and after it is rotated and is in the same direction as wind, the velocity of throw will be reduced, because wind is already assisting the water droplet reach its radius. If the wind velocity is larger than the threshold value, or if it is raining, the system will not start although the switch is turned on. Our product pitch, design concept, and features are presented in an audio-visual format and is awarded the Science Communication ‘Bronze Leaf Prize’ for an outstanding online video presentation in the category of ‘Audience Choice’ on January 26th, 2021.</abstract>

    <title language="eng">OASIS Sprenger</title>
    <abstract language="eng">Our goal is to create a water-efficient sprinkler for residential gardens that is easy to use and responsive to weather conditions. The package comes with two wind sensors - i.e. wind vane and anemometer, which are mounted on a pole. The pole can be placed anywhere in the garden as long as the portable sprinkler stays within a range of 100m. When switched on, the controller on the sprinkler gets continuously updated with the current wind speed and direction using wireless transceivers. The sprinkler can also be controlled through an app on a smartphone. Simple commands such as ON/OFF switch, as well as timers for autonomous watering are possible to set up. For example, setting up the system to water the garden at sunrise, which has been suggested by experts as the most effective time to irrigate plants. Morning irrigation, on the one hand, supplies the grass and plants with enough water to sustain high temperature during the daytime and on the other hand, prevents fungal disease growth and different insects from harming the plants during the night by reducing moisture. Therefore, our sustainable irrigation system not only takes into consideration water conservation, but also provides best methods for having healthy plants in a garden. Our competitive advantage is that our sprinkler is made of durable materials and will save household costs as a long-term investment with efficient water usage methods. There are no other sprinklers in Germany that match our design and usability, which makes our product unique in the market. We will start production and sales in Germany with plans to later expand into the European, North American, and Asia-Pacific region.</abstract>

    <title language="eng">Modelling and Multi-Objective Optimization of a Building Heating Generation System: A case study of Hechingen, Germany</title>
    <abstract language="eng">Nowadays, the world is facing major environmental problems such as climate change and energy scarcity. If we consider only European countries, Heating and cooling industry accounts for more than half of the total EU’s energy consumption. And about 75% of the heat is generated by using fossil fuels. Therefore, the major non-renewable energy sources are depleting at the rapid rate and at the same time also producing the climate-changing greenhouse gases.&#13;
To achieve the climate change objectives, optimised and efficient use of the energy and the decarbonisation of the heating systems are some of the critical steps.&#13;
The investigation process in this thesis involves the modelling and modifying the case study heating system by using Energy Plus and Design-Builder whole building energy simulation software. It also includes the investigation of the three different possible renewable and non-renewable solutions to optimize the current heating system and analyse their effects in terms of total energy consumption (Gas and Electricity consumption) Economic benefits, environmental and other benefits.&#13;
With the detail and adequate data inputs modelling and desired modifications has been done to the heating system and the building properties. The annual simulation has been performed to all the three cases and the results have been analysed.&#13;
The outcome of the analysis of the results shows a significant improvement in overall energy and electricity consumption. Also provides a detailed insight into the total economical investment needed in all three cases and simple payback periods for the investments. And Most importantly the results replicate the environmental benefits such as a considerable reduction in the overall emissions of greenhouse and other toxic gases.</abstract>

    <title language="eng">Investigating the possibilities of AC GMA welding for in-situ alloying in additive manufacturing</title>
    <abstract language="eng">Additive manufacturing is a transformative approach of building 3D objects by layer-upon-layer method, adding digital flexibility and efficiency into the industrial production process. Different categories of materials such as plastics, metals, concrete, etc., can be used for Additive Manufacturing.  At present, WAAM (Wire Arc Additive Manufacturing) is of high interest for many industries, as it allows creating large-scaled metallic components of moderate complexity with high density and good mechanical properties. In this master's Thesis, the capabilities of Gas Metal Arc (GMA) welding for in-situ alloying in multi-material WAAM are being investigated. A 6-axis FD-V6 welding robot by OTC Daihen along with Welbee W400 power supply was used to produce weldments both, with alternating current (AC), as well as pulsed direct current (DC). Two of Photron's High-Frequency cameras were used to investigate the process behavior. An All-in-one oscilloscope, Yokogawa DL850E ScopeCorder, was used to record the voltage and current signals. Single-layer, straight weldments were made to investigate the impact of different welding parameters over the weld seam shape and deposition rate. Later, the setup was extended to induce cold wire to change the chemical composition of the weld seams by in-situ alloying. Therefore, a clamp with adjustable angle, height, and distance was created to position the cold wire feeder along with the GMA welding nozzle. Cross-sections of weldments were taken to extract geometrical information related to the weld seam. In the end, combined experiments were done to investigate the process capabilities of generating weld seams of equal shape but different chemical composition by changing the wire feed speeds and the process parameters. This was the fundamental step for making the process ready for multi-material additive manufacturing. To demonstrate the process performance, two multi-material demonstrator components have been manufactured at the end of the thesis.</abstract>
