Internal Crowd Work, Empowerment, and Agility
(kassel university press, 2024)
In a rapidly changing business environment, organizational agility has become a critical factor for companies seeking to enhance adaptability and competitiveness. This dissertation explores the untapped potential of Internal Crowd Work (ICW) as an innovative and agile form of work organization. Employing a multimethod research approach that includes case studies, a mixed-methods approach, and design science research, this work investigates the characteristics of ICW’s work organization and its impact on employees and ...

Szenografie der Moderne
(kassel university press, 2024)
Der Begriff ‚Szenografie’ hat in nicht wenigen Disziplinen seine Heimstatt gefunden: Architektur, Bühne, Kunst, Design, Kuration, Landschafts- wie Stadtplanung und Kunstwissenschaft sind nur einige der Fachrichtungen, die ‚Szenografie‘ als Bezeichnung raumbezogener ästhetischer Phänomene in ihr Vokabular aufgenommen haben. Es hat sich ein Fachdiskurs zum Szenografischen entwickelt, bei dem nicht selten eine rhetorische Eigenlogik, eine argumentative Dynamik und ein interdisziplinärer Begriffstransfer zu beobachten ...

Hot work tool steel in laser powder bed fusion: from parameter optimization to quality monitoring in industrial application
(kassel university press, 2024)
This dissertation thesis focuses on applying the powder bed fusion with laser beam (PBF-LB) technology on hot work steel. It aims at achieving comparable properties with the products from the traditional manufacturing route. Using the reference powder H13, the influence of various factors, i.e., laser settings (such as laser power and scan speed) and machine settings (such as preheating) on the melting pool morphology and printing defects, is intensively investigated to check the feasibility of printing H13 components ...

Ressourceneinsparpotenziale der „Vorbereitung zur Wiederverwendung“ von Elektro- und Elektronikaltgeräten
(kassel university press, 2020)
Elektro- und Elektronikaltgeräte zählen zu den am schnellsten wachsenden Abfallströmen in Europa. Reparatur und Wiederverwendung können durch eine Verlängerung der Produktnutzungsdauer dazu beitragen, dass weniger Abfall entsorgt werden muss und Ressourcen durch die Vermeidung von Neuproduktion eingespart werden. In der Europäischen Abfallrahmenrichtlinie (2008/98/EG) wird der „Vorbereitung zur Wiederverwendung“ ein hoher Stellenwert eingeräumt; die Abfallvermeidung hat, gefolgt von der „Vorbereitung zur Wiederverwendung“, ...

An Approach to Non-Linear Dynamics of Rotors with Flexible Seals
(kassel university press, 2021)
Contact-free annular seals are used in turbomachinery to reduce leakage flows between areas of different fluid pressures, whilst allowing shaft rotation. In the last fifteen years, a new type of seal was developed, which uses purposefully inserted structural stator flexibility. Thus, the structure is able to slightly deform and can consequently adapt to rotor motion: the inherent risk of rotor-to-stator contact is lowered. This allows for a smaller sealing clearance, therefore lowering leakage and increasing overall ...

Footwear industry, and plastic recycling
(2021-11)
The social and economic dynamics in Ticul municipality in Yucatán is based on labor-intensive and low-tech pottery and shoe manufacturing, contributing thereby 55% of the municipality’s total gross production. Despite its economic importance and employment, there are no environmental policies focused on these economic activities in the community, which has led to environmental, social, health problems in children and concerns of hazardous waste. The article’s objective is to document a successful case of a plastics ...

Control of Stochastic Hybrid Systems based on Probabilistic Reachable Set Computation
(kassel university press, 2018)
This thesis proposes an algorithmic controller synthesis based on the computation of probabilistic reachable sets for stochastic hybrid systems. Hybrid systems consist in general of a composition of discrete and continuous valued dynamics, and are able to capture a wide range of physical phenomena. The stochasticity is considered in form of normally distributed initial continuous states and normally distributed disturbances, resulting in stochastic hybrid systems.The reachable sets describe all states, which are ...

Logistics Social Responsibility and Dynamic Capabilities: Conceptualization and Empirical Analysis
(kassel university press, 2018)
Logistics Social Responsibility (LSR) emerged as a concept to integrate sustainability throughout logistics-oriented processes in the supply chain. Hence, logistics services are linked to sustainability requirements. To meet these requirements, logistics service providers can respond to their responsibility by reducing the ecological and social impact in the supply chain. Moreover, it has been recognized that consumers also need to adapt to sustainability requirements: e.g., by supporting sustainable logistics ...

Analogue objects online. Epistemological reflections on digital reproductions of lantern slides
(2019-09-27)
Many museums and collections publish digital photographs or scans of objects held in their collections in online-accessible databases. What are the epistemological issues at stake when an analogue object is digitised with the aim to ‘illustrate’, ‘document’ or ‘represent’ its analogue original? This essay tackles the question based on practical, hands-on experiences that the author obtained through testing a method for digitising lantern slides. The digital copies achieved in digitisation projects, the author argues, ...
