Summary of developing a test stand for realistic emulation of the cross-sectional area variation of hot rolled wire
The development of innovative measuring technology for process optimization in hot rolling mills becomes more and more relevant because of increasing demands on product quality. Measurement technology for high-resolution non-contact cross-sectional area measurement has shown that the variation in cross-sectional area contains information about the rolling process. This information can be used for the development of new measurement devices and analytical methods for process optimization. The harsh environmental conditions and strict safety regulations result in great effort when implementing a new sensor prototype in hot rolling mills. For this reason, this work presents a mechatronic test stand that can simulate the cross-sectional area variation under laboratory conditions realistically.Die Entwicklung neuartiger Messtechnik zur Prozessoptimierung im Warmwalzwerk gewinnt mit steigenden Ansprüchen an die Produktqualität immer mehr Relevanz. Durch hochaufösende berührungslose Messtechnik zur Querschnittsfächenmessung wurde klar, dass in der Querschnittsfächenvariation viele Informationen über den Walzprozess enthalten sind und für die Entwicklung von Messtechnik und Auswertemethoden zur Prozessoptimierung genutzt werden können. Die rauen Umgebungsbedingungen und strengen Sicherheitsvorschriften führen dazu, dass der Einbau neuer Sensorprototypen nur mit großem Aufwand umsetzbar ist. Aus diesem Grund wird in dieser Arbeit ein Versuchsmodell vorgestellt, welches die Querschnittsfächenvariation mit einer Rollenkette unter Laborbedingungen realitätsnah nachbilden kann
Positive Co-Creation - Konzeption eines Co-Creation-Modells unter Berücksichtigung des Positive Computing
Das Ziel der vorliegenden Bachelorarbeit ist die Konzeption eines neuen Ansatzes − die Positive Co-Creation −, der die Elemente des Positive Computing in die Co-Creation integriert. Dafür wurden in einer Literaturanalyse die bestehenden Schwachstellen der Co-Creation herausgearbeitet, um anschließend die Vorteile des Positive Computing aufzuzeigen. Nach der Entwicklung eines spezifischen Modells der Positive Co-Creation, inklusive der verwendeten Methoden und deren Auswirkungen auf die Wohlbefindensfaktoren, wurde das Modell anhand von Experteninterviews evaluiert und verbessert. Das Ergebnis dieser Arbeit ist ein theoretisches Modell der Positive Co-Creation, welches den Prozess vollständig abbildet und einen Ansatzpunkt für eine praktische Umsetzung bildet. Dieser Ansatz ist gut geeignet, um bestehende Co-Creation-Prozesse anhand von Technologien um die Aspekte des Wohlbefindens zu erweitern.The purpose of the presented bachelor thesis is the conceptualization of a new approach, the Positive Co-Creation, which integrates elements of Positive Computing into the Co-Creation. For this purpose, the existing flaws of co-creation were identified in a literature analysis, in order to subsequently demonstrate the advantages of positive computing. After the development of a specific model of the Positive Co-Creation, including the methods used and their effects on the factors of well-being, the model was evaluated and improved by the suggestions of expert interviews. The result of this work is a theoretical model of Positive Co-Creation, which completely depicts the process and provides a starting point for a practical implementation of this model. This approach can be used to enhance existing co-creation processes by adding the aspects of well-being through technology

Stress im Informatikstudium
Introduction
The aim of this thesis is to examine the Eu- and Distressors of the students of computer science at the Hochschule Ruhr West – University of Applied Sciences. According to the wishes of the new counselling centre for academic stress, stu-dents are to be interviewed for this purpose. In the following, the thesis integrates the known problems in computer science studies. Additionally, the students of computer science should be made aware of the stress with a cartoon video. With the help of the video the future Eu- and Distressors should be recognized in time and help should be fetched from the Hochschule Ruhr West – University of Ap-plied Sciences.
Methods
The investigation of stressors is carried out with a focus group interview (N = 4) and with an online questionnaire survey (N = 120). The significance tests are variance-analytical and group deviations are calculated using t-tests and single factor ANOVA.
Results
The results show differences between the stressors in different groups. Especi-ally in the groups with previously acquired knowledge and with differently asses-sed professional competencies. In particular, the stress level is different between the genders and among computer science students who had fallen ill several times during their studies.
Conclusion
The results are relevant for the current stress situations in computer science stu-dies and for the next studies. In addition, this study also draws attention to the problems in computer science, such as the lack of women in computer science, which could cause stress for students of computer science.Einführung
Ziel der vorliegenden Thesis ist es, die Eu- und Disstressoren der Infomatikstudierenden an der Hochschule Ruhr West zu untersuchen. Hierzu sollen nach den Wünschen der neuen Beratungsstelle für den Studienstress die Studierenden befragt werden. Nachfolgend werden in der Thesis die bekannten Problematiken im Informatikstudium eingebunden. Zusätzlich sollen die Informatikstudierenden auf den Stress mit einem Cartoon-Video aufmerksam gemacht werden. Mithilfe des Videos sollen die zukünftigen Eu- und Disstressoren rechtzeitig erkannt und Hilfe an der Hochschule Ruhr West abgeholt werden.
Methode
Die Untersuchung der Stressoren wird mit einem Fokusgruppeninterview (N = 4) und mit einer Online-Fragebogenerhebung (N = 120) durchgeführt. Die Signifikanzprüfungen sind varianzanalytisch und die Abweichungen der Gruppen werden mit t-Tests und einfaktorieller ANOVA berechnet.
Ergebnisse
Die Ergebnisse zeigen Unterschiede zwischen den Stressoren in unterschiedlichen Gruppen. Vor allem in den Gruppen mit davor erworbenen Vorkenntnissen und mit verschieden bewerteten Fachkompetenzen. Insbesondere ist der Stresslevel zwischen den Geschlechtern und bei den Informatikstudierenden, die mehrmals im Studium erkrankt waren, unterschiedlich.
Schlussfolgerung
Die Ergebnisse sind für die aktuellen Stresssituationen im Informatikstudium und für die nächsten Studien relevant. Außerdem wird mit dieser Studie auch auf die Problematiken in der Informatik, wie z. B. dem Frauenmangel in der Informatik, die den Informatikstudierenden den Stress verursachen könnten, aufmerksam
gemacht

"Help, Accident Ahead!” : Using Mixed Reality Environments in Automated Vehicles to Support Occupants After Passive Accident Experiences
Currently, car assistant systems mainly try to prevent accidents. Increasing built-in car technology also extends the potential applications in vehicles. Future cars might have virtual windshields that augment the traffic or individual virtual assistants interacting with the user. In this paper, we explore the potential of an assistant system that helps the car’s occupants to calm down and reduce stress when they experience an accident in front of them. We present requirements from a discussion (N= 11) and derive a system design from them. Further, we test the system design in a video-based simulator study (N= 43). Our results indicate that an accident support system increases perceived control and trust and helps to calm down the user
Towards a Wellbeing-driven System Design for Intergenerational Collaborative Innovation: A Literature Review
Researchers have previously utilized the advantages of a design driven by well-being and intergenerational collaboration (IGC) for successful innovation. Unfortunately, scant information exists regarding barrier dimensions and correlated design solutions in the information systems (IS) domain, which can serve as a starting point for a design oriented toward well-being in an IGC system. Therefore, in this study, we applied the positive computing approach to guide our analysis in a systematic literature review and developed a framework oriented toward well-being for a system with a multi-generational team. Our study contributes to the IS community by providing five dimensions of barriers to IGC and the corresponding well-being determinants for positive system design. In addition, we propose further research directions to close the research gap based on the review outcomes
A Wizard of Oz Field Study to Understand Non-Driving-Related Activities, Trust, and Acceptance of Automated Vehicles
Understanding user needs and behavior in automated vehicles (AVs) while traveling is essential for future in-vehicle interface and service design. Since AVs are not yet market-ready, current knowledge about AV use and perception is based on observations in other transportation modes, interviews, or surveys about the hypothetical situation. In this paper, we close this gap by presenting real-world insights into the attitude towards highly automated driving and non-driving-related activities (NDRAs). Using a Wizard of Oz AV, we conducted a real-world driving study (N= 12) with six rides per participant during multiple days. We provide insights into the users’ perceptions and behavior. We found that (1) the users’ trust a human driver more than a system,(2) safety is the main acceptance factor, and (3) the most popular NDRAs were being idle and the use of the smartphone
