Previous research has mostly focused on short-term organizational outcomes, and there is limited evidence about the factors that enhance job satisfaction and ensure long-term performance of an organization. To fill this gap, qualitative research was conducted, and data was collected through semi-structured interviews, and the data was analyzed using MAXQDA software. The findings represent some of the factors that significantly increase job satisfaction, such as positive and supportive work environment, flexibility and autonomy at work, career growth and continuous learning opportunities, and fair compensation with meaningful recognition. The participants repeatedly highlighted these factors as a source of enhancing motivation, dedication, commitment, and employee performance. The study suggests that when organizations actively follow and implement these factors, it is more likely to increase employee satisfaction and satisfied employees improve productivity, achieve organizational goals, and increase a higher level of dedication, which ensures organizational long-term performance.}, language = {en} } @masterthesis{Bhalla2025, type = {Bachelor Thesis}, author = {Bhalla, Kushagra}, title = {Strategic Obsolescence Management: Developing a Process-Oriented and Financially Viable Concept}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {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. 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. 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. 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. 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. 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, 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.}, language = {en} } @misc{Friesen2025, type = {Master Thesis}, author = {Friesen, Emilie}, title = {Optimierung des administrativen und pflegerischen Aufnahmeprozesses in einer Akutklinik - Eine praxisorientierte Prozessanalyse}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {Das deutsche Gesundheitswesen steht vor einer Vielzahl von Herausforderungen.

The background of climate change, long supply chains, and growing consumer detachment from food production form the motivation to bring consumers and agricultural producers closer together, especially in urban areas such as D{\"u}sseldorf. Therefore, this study explores which factors influence consumer willingness (intention) and actual purchasing behavior of regional products. The work is based on the Theory of Planned Behavior model (TPB), extended by the additional variable trust and uses a mixed-method approach, which combines literature review, an online survey (n=150), and two semi-structured interviews with local farmers. The statistical results show that attitude, social norms, perceived behavioral control, and trust do not significantly influence regional purchasing intention or actual behavior. The only significant effect can be seen on the willingness to pay higher prices for regional products in different age groups. Older consumers (>36) show significantly higher willingness to pay higher prices than younger consumers (<35). Furthermore, the findings show a clear attitude-behavior gap, where interest or positive attitude towards regional products cannot be translated into real purchasing behavior of regional products. Additional descriptive results show that prices, convenience, and product variety influences grocery choices the most, and social media and recommendations from friends/family are most relevant information sources. Based on these insights, this study develops implications for farmers, consumers, and the city with the goal of strengthening the relationship between local farmers and urban consumers. Key recommendations include hybrid approaches by combining stronger digital visibility with strong personal interaction. Additionally, target group specific actions for younger and older consumers are presented as well as models that combine flexibility with direct exchange such as hybrid CSA.

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. 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\&PBAT blend. 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.

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.

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.

Methodologically, a qualitative case study and qualitative content analysis are applied to LINEG's EMAS statements and relevant regulatory texts, using deductive categories derived from CSRD/ESRS and SASB, complemented by inductive coding to capture LINEG-specific themes.

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.

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 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.}, language = {en} } @masterthesis{Simsek2025, type = {Bachelor Thesis}, author = {Simsek, Seyda}, title = {The Impact of Increasing Use of Artificial Intelligence in Human Resource Management on Employees}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-22687}, school = {Hochschule Rhein-Waal}, pages = {58}, year = {2025}, abstract = {This study examines the application of artificial intelligence (AI) in human resource management (HRM) and its effects on employees, considering both operational benefits and the ethical, social, and psychological implications.

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.

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.

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.

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.

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.

Because of this policy, alternative poultry production methods were created to better meet animal welfare guidelines. To meet this challenge, the University of Bonn launched research into dual-purpose chickens, specifically the British Ixworth breed. Integrating male and female chicken farming offers a new, innovative solution to ethical and sustainability issues in traditional farming by combining egg and meat production. The importance of this research for revolutionizing poultry farming cannot be overstated (Becker et al., 2023). A University of Bonn research team is studying this alternative farming method to determine its productivity and viability. To meet industry needs while prioritizing animal welfare, they evaluate dual-purpose chicken potential by analysing egg (number and weight) and meat (weight) yields. This thesis has four sections, exploring different facets of dual-purpose chickens across four generations via diverse statistical and machine learning methods. First, it examines existing research on various facets of analysing and forecasting individual chicken egg and growth data. It further explores Becker et al.'s 2023 study, "The British Ixworth: individual growth and egg production of a purebred dual-purpose chicken." Moreover, the linear regression, SVR, KNN, and decision tree models were applied to this data for advanced analysis and prediction. The thesis's second part details the methodology, including requirements analysis and dataset preparation. This thesis's third section details how data from four generations of chicken life were analysed to predict future egg production and individual chicken growth. Across generations, individual chickens' average body weight and egg weight all showed an increase in the results. Predictions from linear regression and decision tree models show an increase in individual chickens' growth across generations to come. Egg production forecasts were better with the KNN model. This research will use advanced statistical methods and machine learning to model and assess the generational performance of dual-purpose chickens. These tools will forecast future egg and meat production, thus giving key insights to enhance breeding programs. This research aims to optimize dual-purpose chicken production for growth and egg-laying performance. The researchers eagerly anticipate the results, which will help to shape their future poultry farming projects.}, language = {en} } @masterthesis{Thissen2025, type = {Bachelor Thesis}, author = {Thissen, Erik}, title = {Entwicklung eines prototypischen Tools zur Automatisierung der Erstellung von Linked Open Data aus Open Data Datens{\"a}tzen}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {Linked Data has become an increasingly important publication format for structured information. This thesis explores the extent to which the conversion of Open Data into Linked Open Data can be automated and identifies the main challenges and sources of error. The creation of a prototypical tool was used to gain insights into these challenges and sources of error during the conversion to Linked Data. These were then analyzed and solutions to these problems created. The resulting tool was evaluated with different Open Data datasets. The results show that it is able to partially automate the process of converting Open Data to Linked Open Data and that it succeeded in eliminating key barriers, like the necessary programming skills, currently needed to create Linked Data. This prototype contributes towards decreasing the barrier of entry to create Linked Data and indicates that further research could lead towards the fully automatic conversion to RDF.}, language = {de} } @masterthesis{Olgun2025, type = {Bachelor Thesis}, author = {Olgun, Ismail}, title = {Standardisierung der REST-Services in der IT-Landschaft des BLB NRW}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {Standardisierung der REST-Services in der IT-Landschaft des BLB NRW}, language = {de} } @masterthesis{Rademacher2025, type = {Bachelor Thesis}, author = {Rademacher, Jens}, title = {Evaluierung eines Onboarding-Konzepts im Rettungsdienst mit Handlungskonzeptempfehlung}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {Der Rettungsdienst in Deutschland steht angesichts steigender Einsatzzahlen, des demographischen Wandels und ver{\"a}nderter Erwartungen an Arbeitgeber:innen vor der zunehmenden Herausforderung ausreichend Fachkr{\"a}fte zu gewinnen und zu halten. Vor diesem Hintergrund gewinnt Personalmarketing zunehmend an Bedeutung. Der Erstkontakt im Rahmen des Onboardings ist ein entscheidender Faktor, um Integration, Zufriedenheit und langfristige Mitarbeiterbindung zu sichern. Im Rahmen dieser Bachelorarbeit wurde beim Deutschen Roten Kreuz - Kreisverband Neuss e.V. (DRK-Neuss), ein neues Onboarding-Konzept f{\"u}r angehende Rettungssanit{\"a}ter:innen entwickelt und im Ausbildungszeitraum August bis September 2024 mit 17 neuen Mitarbeitenden erprobt. Ziel war es, das Konzept mithilfe qualitativer Interviews nach Mayring zu evaluieren und Handlungsempfehlungen f{\"u}r eine systematische Einarbeitung im Rettungsdienst abzuleiten. Die Ergebnisse zeigen, dass insbesondere fehlende Standardisierung, inkonsistente Kommunikation und uneinheitliche Betreuung Schw{\"a}chen im bisherigen Prozess darstellen. Gleichzeitig wurden positive Ans{\"a}tze wie die Einf{\"u}hrung eines Begr{\"u}ßungstages und die individuelle Betreuung hervorgehoben. Die Arbeit leitet konkrete Empfehlungen ab, u. a. zur Einf{\"u}hrung eines Paten-Systems, strukturierte Checklisten sowie klare Verantwortlichkeiten im Einarbeitungsprozess. Ein durchdachtes Onboarding ist essenziell, um neue Mitarbeitende effektiv einzugliedern und den Rettungsdienst des DRK-Neuss zukunftssicher im Personalbereich aufzustellen.}, language = {de} }
