Um ein besseres Verst{\"a}ndnis der {\"A}tiologie von subklinischem Wahn zu bekommen, ist es wichtig, die Effekte dieser Risikofaktoren in gesunden Stichproben zu untersuchen. Methodik: Die vorliegende Studie untersuchte 100 gesunde Proband*innen der deutschen Allgemeinbev{\"o}lkerung in Bezug auf subklinisches Wahnerleben. Mittels Frageb{\"o}gen und computergest{\"u}tzter neuropsychologischer Tests wurde subklinischer Wahn, Kindheitstrauma, ToM-F{\"a}higkeiten und der Selbstwert der Proband*innen erfasst. Mehrere statistische Verfahren, wie eine Hauptkomponentenanalyse sowie Korrelations-, Regressions- und Mediationsanalysen wurden genutzt, um die Zusammenh{\"a}nge, Varianzaufkl{\"a}rungen und die pr{\"a}diktive G{\"u}te der genannten Variablen in Bezug auf subklinischen Wahn zu untersuchen. Ergebnisse: Subklinischer Wahn liegt in einem geringen Ausmaß in der Stichprobe vor. Ein signifikant positiver Zusammenhang zwischen subklinischem Wahn und Kindheitstrauma wurde gefunden. Zudem konnten signifikant negative Zusammenh{\"a}nge zwischen subklinischem Wahn und ToM-F{\"a}higkeiten sowie mit Selbstwert gefunden werden. Die Ergebnisse der Regressionsanalyse unterstreichen die pr{\"a}diktive G{\"u}te von Kindheitstrauma und geringem Selbstwert f{\"u}r subklinischen Wahn.

Nepali language is written in Devanagari script, has complex grammatical structure and diverse linguistic features. Due to the absence of balanced datasets, and computational resources for Nepali, achieving optimal result with the latest architecture remains challenging. For this reason, publicly available NLP modelsfor Nepali are very less, making research in this area difficult. This paper attempts to addressthis gap through the use of pre-trained transformer models specially tailored for Nepali from Hugging Face including BERT, DistilBERT, ALBERT, and DeBERTa for sentiment analysis in Nepali tweets on relatively balanced datasets. The models are trained on large Nepali datasets and optimized for NLP tasks involving Devanagari scripts. To evaluate the model's performance, various tokenization strategies are investigated in order to capitalize on transformer-based embedding with the SoftMax function and confusion matrix. The outcomes of models are compared using the same datasets. The study's results shows that DistilBERT achieved the highest accuracy rate of 88\% in Nepali sentiment analysis tasks, followed by BERT and DeBERTa at 83\% and 80\%, respectively. However, ALBERT showed a low accuracy of 70\%.

This bachelor thesis investigates the impact of LGWs on indoor environmental quality, employees' well-being, and performance in the offices of the Facility Management Department of Hochschule Rhein-Waal (HSRW) - Kleve campus. A hybrid methodology is adopted, combining sensor measurements of physical parameters and a self-developed questionnaire assessing perceived LGW impact. The sensors are set up in four offices, three of which featured LGWs, while the questionnaire is distributed online to workers before and after the LGW installation. Eight workers participated in the study, of which 62.5 \% were female, and 37.5 \% were male, with age range between 25 and above 45 years old. The results indicate a positive overall impact of LGWs on office environmental quality and employee well-being. The CO2 concentration was reduced on average by 30 ppm, whereas the relative humidity was increased, on average, by approximately 6 \%. Hence, the LGWs enhanced slightly the air quality in the offices. Moreover, the target group claimed that their motivation level, on average, was raised by 15\% after exposure to the LGWs. Hence, half of them agreed that the LGWs impacted their performance positively. However, challenges emerged concerning LGW technical design and employee engagement with the research. Despite obstacles, the study suggests potential for future improvements in methodology and technical aspects, offering promising project ideas for further research. Furthermore, the overall positive impact of LGW in this study has proven that integrating such systems into work environment can boost the motivation level of the workers and improve the environmental quality in workspaces.}, language = {en} } @misc{Wissigkeit, type = {Master Thesis}, author = {Wissigkeit, Tobias}, title = {Interaction design strategies for conversational video games to accommodate for anomalous user- and AI behaviors: A case study on integration strategies for interaction-based AI technologies in games using participatory design methods.}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-19710}, school = {Hochschule Rhein-Waal}, pages = {51}, abstract = {The recent development of generative artificial intelligence (AI) has inspired some game developers to try and integrate it into games.

We want to leverage their uniqueness as an intended game mechanic and see in what context these strategies can work. To achieve these goals, we researched already existing integrations of generative AI features in games and entertainment as well as possible connections to game mechanics and systems that are not related to AI. Based on this, we created 4 prototypes of conversational games with generative AI characters, which allowed the AI to create anomalous responses and did not limit the player freedom of what they may input. In our 36 participatory design sessions, we found that anomalous user and AI behavior can have a positive influence on the player's experience if a game's story is set up in a way that it can allow new and diverging story threads, that are created by the player and AI, to be integrated and if there are supplementary game mechanics, that allow the player to follow the intended story and complete the game.}, language = {en} } @masterthesis{Khatiwada, type = {Bachelor Thesis}, author = {Khatiwada, Sabin}, title = {AUTOMATION OF SOLAR WATER DISINFECTION (SODIS) ON A SMALL-SCALE USING ARDUINO DUE}, school = {Hochschule Rhein-Waal}, abstract = {Clean water is essential for human health and well-being.

Solar water disinfection(SODIS) is a simple and cost-effective method used to purify water using sunlight, where itinactivates the pathogens and makes the water safe for consumption. This disinfection process involves filling polyethylene terephthalate (PET) bottles with water and exposing them to sunlight for a specified period. The aim of this thesis is to develop a working prototype that exploresthe automation of SODIS on a small-scale using Arduino Due, a microcontroller board that offers advanced features for automation. The prototype consists of the necessary parts to perform SODIS automatically. In conventional SODIS, it is assumed that the required SODIS criteria are met within 6 hours of a sunny day. In contrast, in the prototype microcontroller pumps the water into the PET bottle, monitors sunlight exposure for 6 hours, determines disinfection, and then pumps out the water for consumption only when the threshold values for irradiance are met. If the conditions are not met, the exposure is extended by an hour each time and checked again. The prototype automates the SODIS on a small-scale using cost-efficient components. However, the prototype lacks oxygenation capacity, and there is a possibility of entering an infinite loop if the irradiance values are not met for a long time.

Unfortunately, the research is very limited for low-resource languages like Nepali. This study examines the utilisation of pre-trained BERT-based NERNepal for Named Entity Recognition (NER) tasks in Nepali text. The main goal is to investigate the efficiency of the NERNepal model, which has been pre-trained and fine-tuned on Nepali corpus data for NER. This research provides new insights by evaluating the NERNepal model on two distinct datasets. It addresses unique linguistic challenges specific to Nepali. The study also offers a detailed analysis of the model's strengths and weaknesses. By focusing on diverse datasets, this study shows how adaptable the model is and how its performance varies. These aspects have not been explored extensively before. The EverestNER dataset is one of the largest human-annotated datasets in Nepal so far, and the Nepali_NER dataset is also BIO-annotated for the NER task, which helped to compare the model's prediction. The performance was better on the Nepali_NER dataset in comparison with another selected dataset. The EverestNER dataset contained many complex words for ORG connected with many tokens for a single entity with different contextual meanings and different annotations for the same word in different tokens as per context. Because of this, it created more confusion for the prediction, especially for the ORG entity. It had a similar issue with another dataset as well, but the label annotation was better in comparison. Furthermore, the research tries to clarify the difficulties and constraints related to utilising pre-trained BERT models for NER in low-resource languages such as Nepali. The study focuses on research areas on the efficacy of the model and its performance on two different datasets. Post-training with the EverestNER train dataset was attempted, but due to computational resource limitations, only a maximum of 3 epochs was possible, which did not improve the evaluation. It also has implications for enhancing language processing tools for Nepali. The results show the ability of a pre-trained BERT-based model to improve NER skills for Nepali text. However, further study is required to overcome the current obstacles to identifying complex words. The availability of high computational resources and the possibility of combining other NER approaches with a transformer-based model could increase the performance and robustness of the model.

In today's competitive market, products, services, and customer loyalty are valuable assets, so the program was created to enhance member satisfaction and loyalty with the Value Specialist Club. A mixed-method approach was used to answer the study question and findings, improve member satisfaction, and refine marketing strategies, using a survey as primary data and Qlik Sense as secondary data. Besides, using a survey methodology, the study collected 79 responses from different countries (the United Kingdom, Germany, Belgium, and the Netherlands) and analyzed the data with only 58 Specialist Club member's responses. A reliability examination was additionally accomplished to measure the accuracy of the collected survey data. Qlik Sense, Microsoft 365, and Excel 2016 were used for data analysis and visualization, which involved descriptive analysis, correlation coefficients, and text sentiment analysis. The study results show positive trends in member satisfaction across four markets, but a decreasing engagement rate is noticeable.

The model is made in Python and uses a simplified geometry of reflection, orbit, solar panel parameters, and real-time TLE data. With the developed model it is possible to evaluate a variety of scenarios: single satellite, constellation and global maps of flare distribution with the given parameters.

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.

Performance analysis over 35 moves demonstrates the architecture's high reliability, achieving a 100\% success rate in the software pipeline from command generation to execution planning. The study quantifies the system's primary performance bottleneck, showing that the physical robot movement averaged 22.6 seconds, while the underlying communication latency was negligible at 2.89 ms.

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.

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.

Kontinuierliche Ver{\"a}nderungen, die geringe Haltbarkeit von Wissen und die zunehmende Komplexit{\"a}t der Berufswelt sorgen f{\"u}r die wachsende Bedeutung des Lebenslangen Lernens. Deshalb stehen Arbeitnehmer*innen heute vor der Herausforderung, in der Berufsphase zu lernen und sich neue Kompetenzen anzueignen. Obwohl es eine Vielzahl an Kompetenzmodellen f{\"u}r das Lebenslange Lernen gibt, beziehen sich diese meistens auf die Umsetzung in der Schule. Bez{\"u}glich des Themas Lebenslanges Lernen und Kompetenzen in der Berufswelt existiert noch eine Forschungsl{\"u}cke. Um diese zu schließen wird in dieser Arbeit (1) eine Einf{\"u}hrung in die Thematik Lebenslanges Lernen und Kompetenzmodelle gegeben sowie (2) Kompetenzmodelle hinsichtlich ihrer benannten Kompetenzen analysiert und vor dem Hintergrund des Lebenslangen Lernens in der Berufswelt beurteilt. Das Ergebnis zeigt, dass die Kompetenzen Kommunikation, Kollaboration, Kreativit{\"a}t, kritisches Denken, Probleml{\"o}sekompetenz, digitale Kompetenz, kulturelle Kompetenz, Informationsmanagement, Selbststeuerung, Flexibilit{\"a}t, ethisches Bewusstsein und unternehmerische Kompetenz das Lebenslange Lernen in der Berufswelt f{\"o}rdern. Weitere Faktoren, welche f{\"u}r das Lebenslange Lernen in der Berufswelt ber{\"u}cksichtigt werden m{\"u}ssen, sind: Sinnhaftigkeit, Anwendungsm{\"o}glichkeit und Motivation. Eine Einschr{\"a}nkung dieser Arbeit ist, dass sich nicht alle der analysierten Kompetenzmodelle auf die Berufswelt beziehen, weshalb fraglich ist, wie geeignet die verwendeten Kompetenzmodelle f{\"u}r die Untersuchung sind. Durch die Ergebnisse dieser Arbeit wird hervorgehoben, dass bez{\"u}glich des Themas Lebenslanges Lernen und Kompetenzen in der Berufswelt weiterhin Forschungsbedarf besteht.

The gamification of food is experimented with, mainly for recreational purposes. But it could also be used to achieve a different goal. In this work, an approach to motivating children to eat and like vegetables more is explored. First, the basic perception of vegetables by children is examined and various ideas for games are explored with Cooperative Inquiry. These can be grouped into three categories: building, challenge and randomness. Possible prototypes have been discussed in form of text. A building game has been tested and it had a positive effect on the perception of vegetables of the participating children.

However, many skeptical voices arise regarding impact investing, because some issues hinder the growth the impact investing market (Gray et al., 2015, p.3). Regulatory intervention is needed to overcome the persisting challenges (Martin, 2013, p.18). Therefore, a literature review was undertaken in order to give an overview of existing regulatory measures and initiatives that have been implemented in different regions to foster the growth of the impact investing market, especially in the light of the taxonomy that was recently proposed by the EU. The literature review revealed that many regulations and initiatives have been established across the world, however the regulatory environment regarding impact investing is currently fragmented. Therefore, it is important that governments collaborate to uniformize regulations on a global level. Furthermore, this paper aims to find out how impact funds perform financially in comparison to conventional funds. In order to answer that question a performance analysis, using the Sharpe Ratio as a performance indicator, was conducted. The performance analysis indicated that impact funds perform slightly better than conventional funds. The result goes in line with existing studies that have analyzed the performance of impact investments. This paper indicates that impact investments can compete with conventional investments, but that there is still a lot to be done to bring the market to scale.}, language = {en} } @techreport{Gooren, type = {Working Paper}, author = {Gooren, Lutz}, title = {Verwaltungsrecht}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-5388}, pages = {6}, abstract = {In diesem Arbeitspapier, das an der Fakult{\"a}t f{\"u}r Kommunikation und Umwelt der Hochschule Rhein-Waal entstanden ist, werden die juristischen Grundlagen und aktuelle F{\"a}lle der Rechtsprechung er{\"o}rtert und mit genauen Quellenangaben versehen.}, language = {de} } @techreport{Topp, type = {Working Paper}, author = {Topp, Patrick}, title = {Wehrdienst und Ersatzdienst im Grundgesetz}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-5391}, pages = {6}, abstract = {Dieses Arbeitspapier befasst sich mit dem Wehr- und Ersatzdienst im Grundgesetz.}, language = {de} } @techreport{Hoefs, type = {Working Paper}, author = {Hoefs, Phillip}, title = {Verwaltungsrecht}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-5419}, pages = {6}, abstract = {In diesem Arbeitspapier, das an der Fakult{\"a}t f{\"u}r Kommunikation und Umwelt der Hochschule Rhein-Waal entstanden ist, werden die juristischen Grundlagen und aktuelle F{\"a}lle der Rechtsprechung er{\"o}rtert und mit genauen Quellenangaben versehen.}, language = {de} } @techreport{Thomas, type = {Working Paper}, author = {Thomas, Tobias}, title = {Versammlungsfreiheit in der Verfassung}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-5423}, pages = {6}, abstract = {Die Versammlungsfreiheit und ihre Rechte.
