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.}, language = {en} } @misc{ParayilSivan2026, type = {Master Thesis}, author = {Parayil Sivan, Kavya}, title = {Design and Evaluation of a Mobile Application to Support Autistic Passengers in Air Travel.

This study examined the needs, requirements, and challenges experienced by level 1 and level 2 autistic travellers during air travel and evaluated the effectiveness of a user-centred mobile application in reducing anxiety, improving their travel preparedness, and creating a more predictable air travel experience. A mixed-methods approach was employed for the study. In the beginning, an online survey with 35 participants (21 autistic individuals and 14 support persons) was conducted to understand the need, requirement and challenges of the autistic participants. Findings from the survey showed generally low satisfaction among autistic travellers who has prior air travel experience. The major challenges were related to unpredictability, sensory overstimulation, complex airport procedures, difficulty finding sensory-friendly spaces, and in-flight discomforts. Based on the insights from the survey, a high-fidelity mobile application prototype was designed to work across different airlines and airports providing real-time flight updates, airport and airline specific accessibility information, navigation support, communication cards, and travel checklists. The prototype was then evaluated with 5 autistic participants through a moderated remote usability test followed by a post-test interview and questionnaire. The results showed that features such as real-time flight updates, travel checklists, navigation support, and accessibility information were effective and perceived as helpful in reducing anxiety and increasing preparedness but some discoverability issues were identified in the prototype showing the need to iterate it. Overall, the findings suggest that the application is functionally effective and usable but only partially effective in improving overall travel experience as external environmental factors like airport procedures, in-flight discomforts are beyond the scope of the application. The study also highlights that a thoughtfully designed mobile application can partially support autistic travellers by improving the predictability and helping them prepare for the journey. This study contributes to the growing research on accessibility for autistic individuals by examining air travel challenges and evaluating a user-centred mobile application.}, language = {en} } @misc{OPUS4-2346, title = {13/2026 Korrektur der Pr{\"u}fungsordnung f{\"u}r den Masterstudiengang Usability Engineering der Fakult{\"a}t Kommunikation und Umwelt an der Hochschule Rhein-Waal vom 14.10.2025}, volume = {2026}, number = {13}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-23464}, pages = {10}, language = {de} } @masterthesis{Feider2026, type = {Bachelor Thesis}, author = {Feider, Vivien}, title = {Einfluss von Ern{\"a}hrungswissen auf Ern{\"a}hrungsverhalten und K{\"o}rpergewicht im Kontext der Krebsprim{\"a}rpr{\"a}vention bei Studierenden}, school = {Hochschule Rhein-Waal}, year = {2026}, abstract = {Einleitung: Krebs ist sowohl in Deutschland als auch weltweit eine der h{\"a}ufigsten Todesursachen.

Trotz ihres großen Potenzials zeigen bisherige Studien, dass diese Angebote bislang nur unzureichend genutzt werden. Außerdem wurde die Perspektive der Versicherten dabei bisher nur begrenzt untersucht. Ziel: Ziel dieser Masterarbeit ist es zu analysieren, wie digitale Gesundheitsangebote der Krankenkassen aus Sicht der Versicherten wahrgenommen werden und welchen Einfluss sie auf die Steuerung des gesundheitsbezogenen Verhaltens sowie auf den Zugang zu der medizinischen Versorgung haben. Dabei stehen insbesondere die Bekanntheit, Nutzung und Bewertung dieser Angebote sowie der Zusammenhang mit der digitalen Gesundheitskompetenz im Fokus. Methodik: Methodisch basiert die Arbeit auf einem Mixed-Methods-Ansatz. Zun{\"a}chst wurden qualitative leitfadengest{\"u}tzte Interviews mit Versicherten durchgef{\"u}hrt, um ein vertieftes Verst{\"a}ndnis individueller Wahrnehmungen und Erfahrungen zu gewinnen. Erg{\"a}nzend wurde eine Online-Befragung durchgef{\"u}hrt. Die Datenauswertung erfolgte mittels qualitativer Inhaltsanalyse sowie verschiedener statistischer Verfahren. Theoretisch st{\"u}tzt sich die Arbeit unter anderem auf das Health Belief Model, das Technology Acceptance Model sowie das Konzept der eHealth Literacy. Ergebnisse: Die Ergebnisse basieren auf 10 durchgef{\"u}hrten Interviews und 172 ausgef{\"u}llten Online-Frageb{\"o}gen. Es zeigt sich, dass digitale Gesundheitsangebote vielen Versicherten bekannt sind und {\"u}berwiegend positiv bewertet werden aber die tats{\"a}chliche Nutzung hinter der Bekanntheit zur{\"u}ckbleibt. Besonders ausgepr{\"a}gt ist dieser Unterschied bei Angeboten wie der elektronischen Patientenakte und digitalen Gesundheitsanwendungen. Eine zentrale Rolle f{\"u}r Bekanntheit und Nutzung spielen die digitale Gesundheitskompetenz, die Selbstwirksamkeit sowie externe Hinweise auf die Angebote, insbesondere durch {\"A}rzte. Zudem zeigen sich deutliche Unterschiede zwischen gesetzlich und privat Versicherten. Digitale Gesundheitsangebote werden insgesamt als unterst{\"u}tzend f{\"u}r das Gesundheitsverhalten wahrgenommen und tragen aus Sicht der Versicherten vor allem zu einer schnelleren, jedoch nicht zwingend zu einer einfacheren medizinischen Versorgung bei. Schlussfolgerung: Zusammenfassend verdeutlicht die Arbeit, dass digitale Gesundheitsangebote aus Sicht der Versicherten ein hohes Potenzial zur Unterst{\"u}tzung der Gesundheitsversorgung besitzen.

However, they are computationally expensive to train, with approximately two-thirds of non-embedding parameters residing in Multi-Layer Perceptrons (MLPs). Liu et al. (2024) revisited the long-disregarded Kolmogorov-Arnold representation theorem and demonstrated promising results in specific domains such as symbolic regression and PDE solving. Whether Kolmogorov-Arnold Networks (KANs) generalize to other domains, particularly NLP, remains an open research question. This work systematically evaluates five architecture configurations: MLP baseline, MLP with B-Spline activation, KAN with B-Spline, KAN with Mean aggregation, and Group-Rational KAN (GR-KAN) - across three model sizes (15M, 41M, 124M parameters). Experiments are conducted on text classification ("AG News") and language modeling ("FineWeb") tasks. Identical components (attention, embeddings) isolate performance differences to the feed-forward topology. Statistical validity is ensured through multiple random seeds and parameter-matched comparisons. KAN-based architectures achieve performance parity with MLPs on classification tasks (±0.5 percentage points accuracy). However, they consistently underperform on language modeling, with perplexity increases of +7 to +28 points. Training efficiency overhead ranges from 1.5-2.0× for KANs, while GR-KAN approaches baseline speed. Notably, KANs exhibit significantly higher sparsity (≈ 90\% vs. ≈ 40\%), enabling compression factors of 1.4-1.6× with minimal performance degradation. The MLP+B-Spline control condition reveals that performance deficits stem from KAN topology rather than activation functions. KANs present a viable alternative for discriminative NLP tasks but do not outperform MLPs for generative language modeling. The postulated interpretability advantage through learnable activation functions could not be empirically confirmed - learned functions degenerate to quasi-linear transformations.

They are used in the agricultural sector to bring sellers and buyers together. Farmers advertise about their products and customers give their orders. The payment may be done prior or after delivery. The tools enable farmers to sell without traveling. They also decrease the number of intermediaries. There are sites that allow the customer to rate sellers. There are also people sharing updates on delivery or assisting with tracking goods (Eweoya et al., 2021). Trade in farm goods is evolving in Nigeria, owing to online trade. Most of the farmers would sell in open markets only. The prices were frequently low and middlemen absorbed the better part of the profit (Morepje et al., 2024). It is now easier to connect farmers and buyers by way of mobile phones and enhanced internet. Through online, farmers are able to access directly to homes, stores and even export firms. They save time and minimize wastes because customers do not need to travel in order to make an order. This idea was tested with some of the pioneer platforms in Nigeria (Abubakar et al., 2019). Farmcrowdy began as an initiative to finance small growers and match them with consumers. Agricorp constructed a system to exchange crops such as ginger and grains between states. OjaNow also connects small farms with homes and restaurants who desire fresh food. The services are used to assist farmers in selling more as they remain on their farms. Customers are able to shop and deliver farm products to their front door by making an online order. The platforms also assist the farmers to know what is being demanded as well as the price that the buyers are willing to pay. They operate most of them on basic mobile phones and hence can be used even in places with poor internet connections (Ogbeide-Osaretin and Ebhote, 2020). Online market places have changed the way farmers market their produce because they reach a greater distance than the local area. Most farmers used to sell within their towns only, but now digital platforms enable them to sell to the buyers in such cities 2 like Lagos, Abuja and Ibadan. By using such platforms, they are no longer restricted to set days of the market since sales may be carried out at any given time. This flexibility is time-saving, generates more turnover, and allows farmers to deliver food to a larger group of consumers, such as hotels, stores, and schools (Mani and Singh, 2022). Online tools have also decreased the price of selling farm produce in addition to increasing their markets. Farmers will have the opportunity to self-service their prices and deal directly with buyers by eliminating transport costs and bypassing several intermediaries. This enhanced control on prices does not only enhance their earnings, but also promotes fairness and transparency in trade. Buyers, in their turn, have an advantage of price comparison between various sellers prior to acquiring a particular good, which causes more competitive pricing and low fraud potential (Xiao, et al., 2021). The use of online platforms in integrating with local logistics and transport networks has made delivery much faster. Today many platforms collaborate with professional drivers and delivery crews that provide the delivery of the orders and their transportation at the same time. This has been especially beneficial to perishable products like tomatoes, vegetables, and fruits, whose delivery must be done in a timely manner to preserve their freshness and quality. Consequently, fewer produce is wasted as it goes to waste prior to reaching the consumers hence less waste and the general efficiency of the supply chain. Buyers get healthier and fresher food, and sellers save some money and losses of unsold or spoilt products. This credibility also builds trust between the two parties, as customers get to trust merchants with quality goods, and sellers go out of their way to keep their standards (Agrawal et al., 2021). Farmcrowdy, Thrive Agric, OjaNow, and Agricorp are the ones that have introduced similar systems in Nigeria, where both large-scale and smallholder farmers can engage in an effective and efficient digital trade (Akinwale et al., 2023). Most farmers access them via mobile phones as majority of the applications are phone-based. These sites are very popular in cities where there are greater internet connectivity. They are used by farmers to add the name of crops and buyers to make orders. During harvest, when there is plenty in supply, use is greatest. These tools are more acceptable by young farmers compared to the old. They are also common among traders and restaurants as they require constant supply. Information is also 3 useful on online platforms. Farmers are aware of the demand of crops and their price rates. This helps them plan better. They grow what people want. They also make the best decision regarding the time to sell. Buyers utilize the same information to determine whether the prices can increase or decrease. Other websites provide notifications to make fast decisions. This enhances better planning of farmers and reduces waste (Alkahtani et al., 2021). Online sales have simplified the process of farming, but a number of issues also persist. Previous research has concentrated largely on the rural farmers with little attention paid to the use of these digital tools by the smallholder and urban farmers. Visiting the city like Ibadan and Lagos, farmers have special marketing and distribution issues that are not the same as found in the countryside (Sadiq et al., 2025). A large number of these urban farmers work on small pieces of land and depend on fast sales in order to avoid losses after harvest. Nevertheless, they have problems with the lack of storage facilities and the inadequacy of transport systems (Agri et al., 2020). Few studies have examined these particular constraints in the smallholder farmers (Kabo-Bah \& Bannor, 2025). The available research is rather inclined to investigate farmers access to the online platform instead of studying the impact of these tools on logistics, the speed of delivery, or storage (Trang et al., 2024; Olamide et al., 2024). Consequently, some critical questions will go unanswered, including the ways in which digital platforms can mitigate food wastage or make supply more efficient. Smallholder and urban farmers should be given more attention in future studies to offer a complete picture of the effects of online marketplaces (Akanni and Gabriel, 2020). There are numerous impediments in agribusiness in online marketplaces. Trust is a major concern. Online payments are a worry to the farmers since they are not sure that they are safe. Customers are concerned with counterfeits that are sold via these sites. A lot of farmers also cannot access because of poor power supply and weak network. Other farmers are not phone savvy and like their traditional mode of selling (Eweoya et al., 2021). One of the concerns is capacity building. The farmers should be well trained on how to utilize online sales tools. In their absence, a number of them might not enjoy the use of digital platforms. Hence, further research is necessary that will help to investigate the ways these tools are applied in the day-to-day life of farmers and how they can be trained to achieve better results. Online sales can empower farm 4 markets in Nigeria, albeit, its implementation requires farmers to leverage it effectively. It will be possible to understand which areas these platforms are most effective and which ones provide difficulties and use this information to develop more effective training and support programmes by the government and agricultural support groups. It will contribute to reinforcing what is already effective and bridging the gaps that may still exist (Ogbeide-Osaretin and Ebhote, 2020). Therefore, online stores are influencing the movement of food between farms and Nigerian households. They create new sales opportunities and enhance crop planning but there are still numerous problems. The studies are required to observe the impact of these platforms on storage, transportation as well as urban agriculture. An explicit analysis of the areas will inform policies that can empower farmers and enhance food supply.}, language = {en} } @inproceedings{MenneBeckerSonntagetal., author = {Menne, Jannis and Becker, Rolf and Sonntag, Jan and Waldmann, Anja and Kreter, Ana C. and Wiedemann, Steffi}, title = {AI-Driven Approaches for Animal Welfare Monitoring in Agroforestry Systems}, publisher = {European Federation of Animal Science (EAAP)}, address = {Zuerich}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-23348}, pages = {44}, abstract = {Climate change and shifting agricultural practices require innovative methods to monitor and improve animal welfare for pasture-based and other outdoor livestock. Agroforestry systems, integrating livestock with trees, shrubs and other woody vegetation, might provide shade, shelter, diversified feed and improved microclimates but require advanced monitoring to assess their impact on animal well-being. As part of the Agroforestry Living Laboratory at Rhine-Waal University, we are developing AI-driven, sensor-based solutions to monitor livestock welfare, focusing on small ruminants as well as poultry. To achieve this, we are evaluating AI-based monitoring methods to improve our understanding of animal welfare, while evaluating the role of different data sources. Sensors on animals collect data on movement patterns, and shade use, potentially providing insights into behavioral adaptations and stress responses. Stationary non-invasive camera systems are tested using computer vision and AI to assess posture, interactions, and activity on individual and group levels. Additionally, microclimate sensors might measure environmental conditions such as temperature, humidity, and radiation to evaluate their effects on animal behavior. As agroforestry systems are often in remote areas without external power, we also analyze the potential of self-sustaining sensor networks powered by solar energy and edge computing. These systems minimize energy consumption through deep-sleep modes and decentralized data processing, ensuring continuous monitoring without constant human intervention. By integrating AI-driven pattern recognition with agroforestry systems, we aim to establish an autonomous, energy-efficient monitoring network for further insights into animal welfare, behavioral changes, and environmental adaptation. Though still in development, early findings suggest these methods might enhance data-driven decision-making for sustainable pasture management, benefiting both animal welfare and agroforestry system resilience.}, language = {en} } @misc{OPUS4-2333, title = {09/2026 F{\"u}nfte {\"A}nderungssatzung zur Pr{\"u}fungsordnung f{\"u}r den Bachelorstudiengang International Business and Administration der Fakult{\"a}t Kommunikation und Umwelt an der Hochschule Rhein-Waal vom 19.01.2026}, volume = {2026}, number = {09}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-23332}, pages = {7}, language = {de} } @misc{OPUS4-2332, title = {Zweite {\"A}nderungssatzung zur Pr{\"u}fungsordnung f{\"u}r den Bachelorstudiengang 08/2026 Information and Communication Design der Fakult{\"a}t Kommunikation und Umwelt an der Hochschule Rhein-Waal vom 20.01.2026}, volume = {2026}, number = {08}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-23326}, pages = {5}, language = {de} } @misc{OPUS4-2331, title = {07/2026 Zweite {\"A}nderungssatzung zur Pr{\"u}fungsordnung f{\"u}r den Bachelorstudiengang Bio Science an Health der Fakult{\"a}t Life Sciences an der Hochschule Rhein-Waal vom 23.01.2026}, volume = {2026}, number = {07}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-23314}, pages = {8}, language = {de} } @masterthesis{Ko2026, type = {Bachelor Thesis}, author = {Ko, Tin Long}, title = {The advancement of the ball point game}, school = {Hochschule Rhein-Waal}, year = {2026}, abstract = {Lean management concepts are dynamic, yet students often meet them as static definitions. This thesis advances the Ball Point Pen Game into a production simulation that exposes bottlenecks, queues, work-in-process accumulation and defects while keeping the pen-assembly task simple and standardised. Using design-based research, one design-test-reflect cycle was executed: redesign requirements were derived from Lean and lean-game education literature, implemented as roles, control rules and learning objectives, and piloted in class. The revised game increases complexity without adding product difficulty by introducing an explicit order-release rhythm (takt), separated material and information flows, visual control, and progressive pull logic across three rounds. Across rounds, batch size is reduced stepwise, supermarket/Kanban replenishment is introduced, and a simple poka-yoke prevents assembly errors. A pilot execution with seven students evaluated the redesign using a single-group pre-post knowledge test, a post-game perception questionnaire, and in-game KPIs (throughput, lead time, WIP and defects) supported by observation notes. Results are interpreted as exploratory due to the small sample and lack of a control group. Participants reported high engagement and that game discussions helped translate observations into improvement actions, aligning with prior evidence that simulation games can support understanding and transfer in Lean education.

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. 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. 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.

This study examines how indigenous, non-indigenous, and female smallholder farmers in San Mart{\´i}n, Peru, perceive the benefits and challenges of agroforestry interventions and how these perceptions influence system maintenance, adaptation, and sustainability. The research is guided by the question: How do farmers in San Mart{\´i}n perceive the benefits and challenges of agroforestry interventions, and how do these perceptions shape their adaptive decisions over time? Using a qualitative, comparative case-study design, data was collected through 50 semi-structured interviews and three participatory focus group discussions. The Group Concept Mapping methodological approach used enabled farmers to identify, cluster, and prioritize benefits, challenges, and adaptations using their own categories and reasoning. Findings reveal two main pathways shaping agroforestry trajectories. A maintenance pathway emerges when farmers perceive tangible ecological and labor-related benefits, such as soil improvement, reduced weeding, and microclimate regulation, particularly when market and legality conditions allow value to be captured. An adaptation pathway is triggered when challenges, such as excessive shade, crop-tree competition, legality barriers, or uncertain markets, are perceived as immediate constraints, prompting pruning, thinning, or removal of timber species.

Trotz der zunehmenden Bedeutung eines Betrieblichen Gesundheitsmanagements (BGM) existieren insbesondere an kleinen und mittleren Regionalflugh{\"a}fen bislang wenig systematische und arbeitsplatzspezifische Gesundheitskonzepte. Die Anforderungen an Gesundheit und Einsatzf{\"a}higkeit der Flughafenfeuerwehren werden zudem durch die Vorgaben der Europ{\"a}ischen Agentur f{\"u}r Flugsicherheit (EASA) maßgeblich mitbestimmt. Ziel dieser Arbeit war es, das Belastungs- und Bedarfsprofil der Flughafenfeuerwehr am Airport Weeze zu erfassen und darauf basierend ein ganzheitliches und EASA-konformes Maßnahmenkonzept zur Gesundheitsf{\"o}rderung und Erhaltung der Einsatzf{\"a}higkeit zu entwickeln. Methode: Die Untersuchungen erfolgten im Rahmen eines Mixed-Methods-Designs. Insgesamt 28 der 37 angestellten Einsatzkr{\"a}fte wurden mittels eines teilstandardisierten Fragebogens zu physischen und psychischen Belastungsfaktoren, Trainings- und Erholungsverhalten sowie der Akzeptanz und den W{\"u}nschen zu gesundheitsbezogenen Maßnahmen befragt. Erg{\"a}nzend wurde eine systematische Dokumenten- und Umfeldanalyse sowie eine SWOT (Strengths, Weaknesses, Opportunities, Threats)-Analyse durchgef{\"u}hrt, um strukturelle Ressourcen, Barrieren und Entwicklungspotenziale zu identifizieren. Ergebnisse: Die Auswertung zeigt eine heterogene Alters- und Diensterfahrungsstruktur. Belastungsschwerpunkte wurden im Dienst durch Schichtdienst, L{\"a}rmexposition und sitzende T{\"a}tigkeiten verzeichnet. Gleichzeitig existieren L{\"u}cken in der Erfassung psychischer Belastungen und in der systematischen Dokumentation des Dienstsports. Dar{\"u}ber hinaus wurde festgestellt, dass bislang keine einheitlichen Trainings- oder Testungsverfahren f{\"u}r den Dienstsport vorhanden sind, sodass die k{\"o}rperliche Leistungsf{\"a}higkeit der Einsatzkr{\"a}fte nicht regelm{\"a}ßig {\"u}berpr{\"u}ft oder gezielt gef{\"o}rdert wird.

Existing research rarely examines multiple industries together or evaluates competitiveness using both time perspectives, creating a clear research gap. The research question asks how green and traditional companies differ in financial performance, innovation, consumer trust, and regulatory responsiveness. The hypothesis proposes that green companies show lower short-term competitiveness, but higher long-term competitiveness than traditional firms. A qualitative comparative case study approach is applied using secondary data, including annual reports, sustainability disclosures, ESG ratings, and international regulatory frameworks. Six companies are analysed: Tesla and Toyota in the automotive sector, Hilton and Wyndham in hospitality, and Kering and H\&M in fashion. Their competitiveness is assessed through a structured framework that distinguishes between immediate business outcomes and long-term strategic development. The findings show that traditional companies perform better in the short term due to efficient cost structures, established operating models, and stable supply chains. Green companies, however, achieve stronger long-term competitiveness by investing in innovation, transparency, and alignment with tightening regulatory and consumer expectations. Tesla, Hilton, and Kering demonstrate superior long-term performance, while Toyota, Wyndham, and H\&M maintain advantages mainly in the short term. The results support the hypothesis and highlight sustainability as an important driver of long-term competitiveness.

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. 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. Fibre morphology was analysed by scanning electron microscopy (SEM), revealing fibrous structures and parameter-dependent differences in diameter distributions and mat heterogeneity. 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 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. Overall, the results support SBS with DMC as a viable route to produce PLA fibrous mats and show clear process-structure relationships.

UVA and UVB radiation in particular cause hair to become drier and more porous, making it more prone to structural damage. These effects can be attributed to the breakdown of the hair protein keratin. Suitable in vitro and ex vivo models were used to demonstrate the degradation of hair keratin by UV radiation and to illustrate this visually using real strands of hair. The aim of this work was to develop physically effective protection for hair against UV radiation and to demonstrate the protective effect of such sunscreen products on hair keratin using a specially developed methodology. In line with the current trend toward "skinification" concepts and formulation approaches from facial care were transferred to the hair care sector. For this purpose, a sun protection spray with modern oil-soluble and water-soluble UV filters was developed. Particular attention was paid to the optimal solution of the UV filters in an aqueous O/W emulsion and the subsequent sprayability of the emulsion in order to be able to apply the product evenly to the hair. The aspect of sustainability also played an important role in the selection of raw materials and the manufacturing process. In vitro tests were performed on specially manufactured keratin-containing agarose plates, irradiated with UV light, and then evaluated photometrically using a BCA assay. The samples treated with the product showed a significantly higher keratin content compared to untreated samples, indicating a protective effect against UV-induced keratin degradation. In addition, ex vivo tests on real hair strands confirmed a positive effect of the product treatment on the appearance and feel of the hair. The methodology developed represents an innovative approach to investigating the protective effect of hair sunscreen products on hair keratin and provides a basis for further research and product development.

These nitrogen-containing pigments contribute to stress tolerance and have applications as natural colorants and food supplements due to their antioxidant properties. This study investigated the effect of high salt stress (200mM NaCl) on growth, physiological performance, betalain accumulation, pigment composition, and gene expression in six Amaranth accessions over a 14-day period of exposure. Phenotypic observations revealed visible stress symptoms, such as reduced growth and leaf senescence, whereas physiological parameters such as photosynthesis, stomatal conductance, transpiration, and internal CO2 concentration remain unaffected by salinity. Spectrophotometric quantification showed an increase in betalain concentrations after the 14-day testing period in all genotypes, salt treatment showed minor inconsistent effects. The total betalain concentration was quantified, the results per accession are for Ama 104 3.013 mg/100 g FW, Ama 124 2.944 mg/100 g FW, Ama 154 4.088 mg/100 g FW, Ama 157 4.735 mg/100 g FW, Ama 162 2.227 mg/100 g FW, Ama 169 18.248 mg/100 g FW. Characterization of betalains with HPLC-DAD-MS analysis confirmed the presence of amaranthine and isoamaranthine as the dominant betalain present in Amaranth leaves, which is consistent with the known betalain presence of grain amaranth species; no betaxanthins were detected. Gene expression analysis of CYP76AD2, DODA2, DODAα2, and SOS1 revealed no significant transcriptional induction under salt stress after the 14-day salt stress treatment. These results may suggest that betalain accumulation occurred due to normal developmental regulation rather than a salinity effect. However, analysis 24-48 after salt stress induction is recommended to conclude. The combined results reveal variation in pigment levels and salinity-stress response and demonstrate the resilience of grain amaranth to increased salinity exposure. The variation in pigment accumulation indicates the importance of selecting high-betalain accessions for industrial applications at an early stage. Future research should focus on early transcriptional levels and regulatory mechanisms to better understand stress response in the betalain pathway of these amaranth accessions.}, language = {en} } @misc{Aziz2025, type = {Master Thesis}, author = {Aziz, Sk Tarik}, title = {The Impact of Employee Job Satisfaction on Organization's Long-Term Performance}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-23053}, school = {Hochschule Rhein-Waal}, pages = {266}, year = {2025}, abstract = {The purpose of the study is to investigate the impact of employee job satisfaction on organizational long-term performance and focus on the key factors that increase satisfaction among employees.

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.

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.

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.

Lebensjahr auftreten. Angesichts der allgemein prognostizierten Zunahme von Demenzerkrankungen und des steigenden gesetzlichen Renteneintrittsalters erh{\"o}ht sich die Wahrscheinlichkeit, dass Menschen mit beginnender Demenz noch aktiv am Erwerbsleben teilnehmen. W{\"a}hrend international bereits erste empirische Erkenntnisse zum Umgang mit demenziell erkrankten Mitarbeitenden vorliegen, besteht f{\"u}r den deutschen Arbeitskontext bislang eine Forschungsl{\"u}cke. Um diese L{\"u}cke zu adressieren, wurde im Rahmen der vorliegenden Untersuchung ein exploratives Stimmungsbild zur Wahrnehmung, Sensibilisierung und Handlungsbereitschaft im Umgang mit (potenziell) an Demenz erkrankten Mitarbeitenden erhoben. Hierzu wurden qualitative, halbstrukturierte Expert:inneninterviews mit Fachpersonen aus dem Betrieblichen Gesundheits- und Eingliederungsmanagement sowie aus der Demenzberatung durchgef{\"u}hrt und mithilfe der inhaltlich-strukturierenden qualitativen Inhaltsanalyse nach Kuckartz ausgewertet. Zur Ber{\"u}cksichtigung der Perspektive von Menschen mit Demenz wurden dar{\"u}ber hinaus Interviews mit Betroffenen und ihren Angeh{\"o}rigen, die im Rahmen der Studie STELDA (Untersuchung zu Stigmatisierungserfahrungen von Menschen mit Demenz und ihren Angeh{\"o}rigen) erhoben wurden, im Zuge einer Sekund{\"a}ranalyse erneut analysiert, um vertiefende Einblicke aus der Betroffenenperspektive in das Thema Demenz am Arbeitsplatz zu erhalten. Die Untersuchung verdeutlicht, dass Demenz im betrieblichen Kontext bislang kaum thematisiert wird. Es zeigt sich ein deutlicher Sensibilisierungs- und Informationsbedarf sowie begrenzte strukturelle Voraussetzungen f{\"u}r die Weiterbesch{\"a}ftigung betroffener Mitarbeitender. Gleichzeitig bestehen Potenziale innerhalb etablierter BGM- Strukturen und im Ausbau der Zusammenarbeit mit externen Beratungsstellen, die eine verbesserte Unterst{\"u}tzung erm{\"o}glichen k{\"o}nnten.

The objective was to assess the mechanical, manufacturing, and economic feasibility of introducing CF-PEEK into restorative dentistry through an engineering-driven approach. 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. Results show that CF-PEEK exhibits a modulus close to natural dentin and lower density, offering improved biomechanical compatibility and reduced stress transmission. Additive manufacturing (3D printing) was identified as the most flexible and sustainable production method, minimising material waste and enabling customised crown fabrication. 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.

It evaluates the extent to which LINEG's EMAS-based environmental disclosures align with CSRD/ESRS and where extensions are required to meet comprehensive ESG obligations. The analysis is grounded in Stakeholder Theory and Valente's Stage Model to connect accountability expectations with organizational sustainability maturity. 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. Peer utilities are referenced to contextualise findings. Findings show a strong environmental foundation— externally validated data on energy, emissions, water, and biodiversity—indicating partial readiness for ESRS E-standards. However, material gaps remain in social and governance areas (e.g., workforce metrics, affordability and service quality indicators, stakeholder engagement processes, and board-level oversight of sustainability). Applying Valente's model positions LINEG between Defensive and Isolated stages: largely compliancedriven, with initiatives not yet embedded across strategy and governance. The thesis proposes a roadmap to consolidate environmental disclosures into ESRS structures, conduct a double-materiality assessment, expand S and G indicators, formalise stakeholder engagement, and assign clear governance responsibilities. Limitations arise from a single-case, document-based approach and the evolving German transposition of CSRD, which may adjust timelines and specific requirements once fully enacted.}, language = {en} } @misc{OPUS4-2281, title = {21/2025 Vierte {\"A}nderungssatzung zur Pr{\"u}fungsordnung f{\"u}r den Masterstudiengang Gesundheitswissenschaften und -management der Fakult{\"a}t Life Sciences an der Hochschule Rhein-Waal vom 21.05.2025}, volume = {2025}, number = {21}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-22814}, pages = {6}, language = {de} } @masterthesis{MohajeriNejad2025, type = {Bachelor Thesis}, author = {Mohajeri Nejad, Mostafa}, title = {Development and implementation of an adaptive control system for automizing and optimizing the performance of a rolling fluid (setur) hydro-turbine}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {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. 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. 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.

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. 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. 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. The project demonstrates a possibility of adaptation of those algorithms and their feasibility.
