    Pepper: Der halbautonome, humanoide Service-Roboter

    No full text
    Die vorliegende Arbeit untersucht die Integration großer Sprachmodelle in die Steuerung humanoider Roboter, am Beispiel der Anbindung von ChatGPT an den Service-Roboter Pepper. Motivation der Arbeit ist die Frage, wie moderne Sprachmodelle die Interaktionsfähigkeit älterer Roboterplattformen verbessern können, sodass Roboter wie Pepper trotz ihres Alters und begrenzter physischer Fähigkeiten in sozialen und bildungsbezogenen Anwendungen relevant bleiben. Ziel der Forschung ist es, Peppers Kommunikations- und Interaktionsmöglichkeiten durch die Kombination seiner bestehenden und möglichen Funktionen mit den Sprachverarbeitungsfähigkeiten von ChatGPT zu erweitern. Hierzu wurde ein System entwickelt, das kontextbasierte Codes (Actioncodes) verwendet, die es dem Sprachmodell ermöglichen, Peppers Verhalten dynamisch zu steuern und flexibel auf Situationen zu reagieren. Dazu gehört die technische Anbindung von ChatGPT an die QiSDK, die Implementierung spezifischer Actioncodes sowie die Definition einer Persönlichkeit und kontextuellen Wissensbasis für den Roboter. Das System wurde auf Basis vorangegangener Feldversuche im Labor getestet und evaluiert. Die Ergebnisse zeigen, dass die Integration von ChatGPT Peppers Interaktionsfähigkeit signifikant verbessert, indem die Kommunikation natürlicher und die Reaktionen des Roboters flexibler werden. Diese Arbeit demonstriert, wie moderne Sprachmodelle dazu beitragen können, ältere Robotersysteme zu modernisieren und ihre Einsatzmöglichkeiten erheblich zu erweitern

    Development of a Key Performance Indicator Based Method for the Evaluation of Scan Strategies

    In the Laser powder bed fusion of metal, the laser beam melts and fuse the powder material to produce the part layer by layer. The scan strategy, which defines the pattern in which the laser moves on the powder bed, affects the mechanical properties, residual stress and quality of the parts. There are many scanning strategies and it is difficult to select the appropriate scanning strategy based on the required quality of the parts. In this thesis, key performance indicators related to scanning strategy are developed, based upon the literature, which can influence the quality of the parts like high density and low surface roughness. The developed KPI is used to evaluate the scanning strategy of printed parts and their results on surface roughness and density. The developed KPIs are integrated into custom software to collect the data for evaluation of scanning strategy. The correlation analysis is also performed to understand the relation between developed KPI and quality of the parts (surface roughness and density). The results shows that developed method can be used for evaluation of the scanning strategy but it needs to be further improved to get more accurate results

    Sustainability and the Fast Fashion Paradox of Gen Z - A qualitative Analysis of Consumer Characteristics and Cognitive Dissonance

    No full text
    This study delves into the fashion preferences and decision-making processes of six Gen-Z participants, shedding light on their intricate choices. Despite a shared emphasis on visually appealing fashion and moderate sustainability knowledge, participants showed a limited inclination towards sustainable choices. Notably, price takes precedence, reflecting a prevalent budget-conscious approach. Surprisingly, participants exhibit a low preference for consistency, challenging the expectation of significant cognitive dissonance in their fashion choices. The results suggest a minimal role of cognitive dissonance, indicating a relaxed decision-making style. The study underscores the dominance of ultra-fast fashion, design, and affordability in participants' choices. Future research is encouraged to address and reduce Gen-Z's (ultra-) fast fashion consumption, promoting sustainability knowledge and a greater preference for sustainable fashion

    The Impact of Increasing Use of Artificial Intelligence in Human Resource Management on Employees

    No full text
    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. Its analyzes real-world applications of AI in recruiting, performance management, talent development, and HR administration using qualitative secondary data from academic papers, industry publications, and case studies published between 2018 and 2024. To examine employee experiences, organizational issues, and ethical implications, a combined analytical approach is used, which incorporates the Technology Acceptance Model, Job Demand-Control Model, human-centered AI concepts, and the European Commission's Ethics Guidelines for Trustworthy AI. While AI can increase effectiveness, reliability, and strategic HR results, the findings highlight concerns about algorithmic bias, reduced human engagement, and risks to employee autonomy and well-being. This paper addresses the significance of organizational planning, transparency, and responsible oversight in AI implementation, highlighting that technology should supplement rather than replace human judgment. The study offers an understanding of the human-centered and ethical aspects of AI in HRM, as well as insights for organizations seeking to use AI responsibly while maintaining employee trust and engagement

    Emotionserkennung über den Einsatz von Messinstrumenten.

    No full text
    Die zuverlässige Erkennung von Emotionen mittels Herzfrequenzvariabilität ist eine große methodische Herausforderung, da Verfahren von der Emotionsinduktion über die Datenbereinigung bis zur Modellierung stark voneinander abweichen. In diesem Method-Paper wurden die verschiedenen methodischen Entscheidungen systematisch dargestellt und anhand eines exemplarischen Studiendesigns verdeutlicht. Die Untersuchungen haben gezeigt, dass bisher kein einheitliches methodisches Vorgehen definiert wurde. Demnach sollten das Studiendesigns an die gewünschten Anwendungssituationen angepasst werden. Untersuchungen im Rahmen der Emotionsforschung sollten demnach mit einer festen Zielsetzung und umfassender Planung erstellt werden
