N2 - This study has evaluated the heat loss potential and energy consumption at the industrial level. Notably, heat loss on a large scale at the industrial level has been recognized as neither economically nor environmentally sustainable. Moreover, the continued use of fossil fuels (natural gas) has been reviewed as unsustainable due to their adverse effect and limited availability, posing challenges for the present and future. Heat loss is optimized at the continental production site in Villingen-Schwenningen. Heat loss through exhaust fans, which extract heat from inside the building and release it to the environment to maintain the internal temperature, has been analysed. The released heat is lost in the environment. To recover this energy loss, the integration of a plate-to-plate heat exchanger is proposed. This approach recovers the rejected heat to preheat the incoming fresh air supply, replacing the traditional heat coil operated on natural gas. Additionally, the transition of natural gas to biogas has been explored. The district heating twin pipe (DN 80) is considered for the smooth flow of thermal energy. For this project, a financial analysis of return on investment (ROI) for 10 years is conducted, the thermal energy flow rate over 2.1km, and heat loss during the transfer phase are calculated. The results have shown significant importance for the recovered energy by integration of a plate-to-plate heat exchanger; yearly, 1.2 GW of energy can be recovered, reducing the consumption of natural gas and making a complete transition towards biogas, economically and environmentally beneficial.

Y1 - 2025 ER - TY - THES A1 - Flören, Marie Catherine T1 - Immersives Erleben Ein Einblick in das Immersionsverständnis der Anbieter:innen immersiver Besucherattraktionen N2 - Immersive experiences have been gaining popularity for the past few years within the tourism industry. This bachelor thesis aims to collect and present the understanding of the word immersion as it is interpreted by different organizers of immersive experiences within the tourism industry. Further, this thesis seeks to collect strategies and artistic methods used in the creation of immersive events and attractions to understand which are used to facilitate an immersive experience for the visitors. Moreover, looking to the future, the thesis also intends to garner possible future developments within the immersive industry, as predicted by the organizers interviewed for this thesis. To answer these questions, five organizers and designers of different immersive experiences were interviewed. The results show that the understanding of the term immersion differs between different organizers. It was possible to identify that the individual definitions range from overly spatial and design-oriented to strongly narrative-oriented, as well as an immersion as the absorption of an environment or the participation within the environment. Furthermore, it was possible to identify multiple strategies used in immersive experiences, some of which have not yet been found in current research. The interviewed organizers suggest that immersive design will be a trend within the tourism industry. However, they also state that the term is currently already being overused and diluted in its meaning. This work establishes a basis on which future research can expand by further investigating the definition of the term ‘immersion’ within the tourism industry.

Der akute Herzinfarkt mit ST- Streckenhebung ist eine mögliche Manifestationsform. Zu den Risikofaktoren für die Entstehung von Herz-Kreislauf-Erkrankungen zählen viele modifizierbare Parameter (Nikotinkonsum, Übergewicht, Bewegungsmangel usw.), so dass das Risiko an einem Herzinfarkt zu erkranken, zumindest teilweise beeinflussbar ist. Mit dem „Gesunde[n]-Herz-Gesetz“ wollte die 24. Bundesregierung der Bundesrepublik Deutschland auf diese Mechanismen aufmerksam machen und Präventionsprogramme zur Reduktion kardiovaskulärer Risikofaktoren etablieren. Die vorgestellte Arbeit befasst sich mit dem kardiovaskulären Risikoprofil sowie demographischen Daten der Herzinfarkt-Patienten in der Kardiologie des katholischen Karl-Leisner-Klinikums (St. Antonius Hospital Kleve und Marienhospital Kevelaer) im Vergleich der Jahre 2014 und 2024. Es soll untersucht werden, wie das Risikoprofil der Herzinfarkt-Patienten in den beiden Krankenhäusern aussieht, und wie es sich im Vergleich der letzten 10 Jahre verändert hat. Ziel der Arbeit ist es, herauszufinden welches Patientenkollektiv in den kardiologischen Abteilungen des katholischen Karl-Leisner-Klinikums von Herzinfarkten betroffen ist, um gezielt Präventionsmaßnahmen abzuleiten. Hierfür wurden die Krankenakten aller Patienten, die im Jahr 2014 im Krankenhaus Kleve sowie im Jahr 2024 in den Krankenhäusern Kleve und Kevelaer mit einem ST-Hebungsmyokardinfarkt behandelt wurden, eingeschlossen. Mittels Student’s T-Test und Mann-Whitney-U-Test wurden demographische Parameter, Laborwerte und weitere kardiovaskuläre Risikofaktoren zwischen den beiden Zeiträumen verglichen. Es zeigt sich eine signifikante Zunahme von Gesamtcholesterin und LDL-Cholesterin im Jahr 2024 verglichen zu 2014. Außerdem besteht die Tendenz zur Abnahme der Nierenfunktion zwischen den untersuchten Jahren. Im Hinblick auf weitere Risikofaktoren wie manifeste Atherosklerose, Diabetes mellitus und arterielle Hypertonie zeigt sich eine Tendenz zur Entwicklung eines multimorbiden Patientenkollektives. Als Ansatzpunkte zur Optimierung des Risikoprofils seien Maßnahmen zur Raucherentwöhnung, Reduktion von Bewegungsmangel sowie eine Verbesserung der Gesundheitsvorsorge und -aufklärung zu nennen.

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. 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. 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. 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. 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.

Its analyzes real-world applications of AI in recruiting, performance management, talent development, and HR administration using qualitative secondary data from academic papers, industry publications, and case studies published between 2018 and 2024. To examine employee experiences, organizational issues, and ethical implications, a combined analytical approach is used, which incorporates the Technology Acceptance Model, Job Demand-Control Model, human-centered AI concepts, and the European Commission's Ethics Guidelines for Trustworthy AI. While AI can increase effectiveness, reliability, and strategic HR results, the findings highlight concerns about algorithmic bias, reduced human engagement, and risks to employee autonomy and well-being. This paper addresses the significance of organizational planning, transparency, and responsible oversight in AI implementation, highlighting that technology should supplement rather than replace human judgment. The study offers an understanding of the human-centered and ethical aspects of AI in HRM, as well as insights for organizations seeking to use AI responsibly while maintaining employee trust and engagement.

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. 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. 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.

It evaluates how the assessment of these aspects influences the willingness to pursue a life and career abroad through a review of existing literature and an online survey conducted by the author. The theoretical background draws on Push-Pull Theory to present migration motives, Neoclassical Economics and the New Economics of Labor Migration to highlight economic reasons and the evaluation of cost and benefits, and Expectancy-Value Theory and Self-Determination Theory to examine the connection of expectations and intrinsic motivations and values related to migration intentions. The data of the survey, conducted among German university students and graduates shows that the economic assessment is not a main motivator for a life abroad but a mix of socioeconomic factors can increase the willingness to go abroad. The study highlights the importance of personal reasons, especially personal growth and cultural experience as it increases the willingness among educated Germans to migrate. Professional growth particularly, if evaluated as better abroad as well as a bad assessment of the German labor market increase the willingness for international mobility. The thesis contributes to a better understanding on the dynamics behind the international mobility intentions among highly skilled individuals in Germany.

This study introduces a novel AI-based framework based on AI technology, using GANs along with Stable Diffusion models to automate comic development. This study looks at juxtaposing narrative outlining through text with automated visual generation toward an integrated system that produces adaptable comic panels with appropriate visual structure. The research methodology that the project has followed can be built on three cornerstones: advanced GAN schemes for text generation and pre-processing, followed by image synthesis through Stable Diffusion. A specially developed algorithm for speech bubbles determined the optimal placement of that text, so it would function well and maintain a semblance of beauty. By iteratively refining and tuning the model, this system was evaluated. Initial observations regarding visual coherence and narrative alignment were hopeful, but further tests using quantitative metrics-for instance, FID for images and BLEU for text, as well as broader user feedback-would be needed to validate the efficacy of the model entirely. The impediments were, however, GAN mode collapse, irregular speech-bubble layout, and inconsistent artistic styles. Further research would uncover the potential role of AI systems in easing the comic generation process for creators, educators, and designers of digital content to enhance accessibility and efficiency. This method shows promising applicability in various domains like automated narratives, customizable comics, and educational material. Further along the way, the scientists plan to improve panel storytelling, create an intuitive interface, and expand the dataset to include more artistic styles. Such enhancements could maximize the gain from automated comic conception.

N2 - African baobab (Adansonia digitata L.) tree parts are mostly harvested for nourishment and economic purposes. However, the products are only extracted from the wild and are threatened by depletion which necessitates research into the species domestication and cultivation. Mycorrhization involves promoting foreign and native mycorrhiza linkages to improve the roots’ efficiency in nutrients and moisture acquisition. While origin can impact the development of A. digitata, its impact on the species mycorrhization potential is not well understood, and was investigated in this thesis. A. digitata plants were grown from seeds of semi-arid, sub-humid and humid zone origins of Benin inside a controlled climate chamber. The seedlings from each origin received native soil, commercial mycorrhiza fungi (alternative) and control treatments. Growth parameters were determined before treatments application and at termination. Models combining the effects of treatment, zone origin, unique tree characteristics and block arrangement were used for statistics. Only seedlings of the humid zone origin had significantly higher initial leaf count than counterparts from other origins. Insignificant differences among origins and treatments were observed for all the other parameters. Inconsistent significant interaction of treatment and origins was observed for final leaf count, stem diameter, root collar diameter, fresh taproot and dry lateral root weights. The results indicated A. digitata seedlings’ ability to show morphological similarities when grown under uniform conditions irrespective of the genetic variations which might exist among seedlings. These growth trends were not 1 affected by the presence of commercial and native microbes. Inconsistent interaction effects warrant further investigation to ascertain specific individual tree seedlings which might have been significantly impacted by treatments.

In Germany, the shift from internal combustion engine vehicles (ICEVs) to electric vehicles (EVs) has become a key focus of national and EU climate policies. Nevertheless, the transition to EVs is associated with a multitude of factors that need to be considered, including emissions from manufacturing, the energy used during operations, and post-operational treatment. This thesis focuses on the design, development, and refinement of a web-based CO₂ Lifecycle Emission Calculation tool that compares cradle-to-grave emissions of EVs and diesel ICEVs based on different driving scenarios in Germany. It is based on Life Cycle Assessment (LCA) Methodology as indicated in ISO 14040/14044. With the tool, the manufacturing, operational, and end-of-life emissions are estimated based on validated datasets from peer-reviewed literature and authoritative bodies (IPCC, IEA, UBA). The tool’s modular structure, which was developed in Python with the Streamlit framework, also allows for other languages to be added, selection of the region’s grid mix, scenario comparisons, and results visualization in multi-level dashboards. Findings of the literature review show that the tool is accurate for both types of vehicles as the known lifecycle emissions ranges for both types are captured. Carbon payback periods for EVs ranged from less than three years to over eight years depending on the grid context, from renewable-rich to coal-intensive. Sensitivity analysis demonstrates that both grid CO₂ intensity and annual mileage hold the greatest influence over lifecycle results. This research contributes to sustainability as it fills the void that exists between academic LCA models and consumer-facing applications with a transparent, reproducible, and user-configurable decision-support tool. Improvements can be made by incorporating real-time grid emission data, expanding the vehicle datasets, and including additional CO₂ environmental impact categories.

W. Erickson and aksimovic 2020). I develop a prototype digital controller for a buck converter, which uses a trained GPR model to predict the PWM duty cycle required to obtain a desired output voltage. I use an Analog Discovery 2 (AD2) (Digilent Inc. n.d.) as an interface between the GPR controller and the buck converter hardware by providing real-time voltage measurements to the controller and generating the PWM signal. I compare the performance of the GPR controller with the TPS629210DRLR Integrated Circuit (IC) (Texas Instruments 2022), which uses an analog control method and serves as the reference performance standard. I compare the performance of the GPR controller and the IC based on their ability to maintain a target voltage during a load change involving an RC load. The results are evaluated based on the voltage regulation accuracy and load voltage settling time. The results show that both controllers are able to set the load voltage within 1% of the target value. However, the GPR controller has a settling time around 3 times longer than the analog controller. The longer settling time is due to latencies from communication with the AD2 and the time required for duty cycle computation. Despite this, the settling time difference is short enough to consider the digital GPR controller competitive to the reference analog control method, especially since the current prototype is not optimized to reduce these latencies. The findings of this thesis highlight both the potential and limitations of the digital control of a buck converter.
