Statik und Einflussfunktionen - vom modernen Standpunkt aus
(2024-01)
Moderne Darstellung der Statik der Stab- und Flächentragwerke mit besonderer Betonung der Einflussfunktionen und ihrer Bedeutung für das Rechnen mit finiten Elementen und Randelementen. Aus den Greenschen Identitäten werden die Grundlagen der Statik und des numerischen Rechnens in der Statik entwickelt und gezeigt, wie die Einflussfunktionen wesentlich die Genauigkeit von Finite-Elemente-Berechnung bestimmen. Die Kombination von finiten Elementen und Einflussfunktionen gewährt, über die Numerik hinaus, grundlegende ...

Optimierung des Risikomanagements als Beitrag zur Steigerung des Projekterfolgs bei Produktentwicklungsprojekten am Beispiel der Automobilindustrie
(2024)
Die zunehmende Projektifizierung der letzten Jahrzehnte hat dazu geführt, dass der Beitrag von Projekten zur Erreichung der Unternehmensziele und damit zur unternehmerischen Wert-schöpfung in gleichem Maße gestiegen ist. Gleichzeitig sind Projekte aufgrund ihres einzigar-tigen Charakters mit Risiken und Unsicherheiten behaftet, deren Auftreten im Kontext der Produktentwicklung in der Automobilindustrie durch den Produktivitätsdruck sowie die stetig steigende Komplexität und Dynamik noch verstärkt wird. Die negativen ...

Risk Communication during the COVID-19 Pandemic
(2024)
In this PhD project it was aimed to learn about the potential and the challenges of risk communication in systemic risks by conducting applied research during the COVID-19 pandemic. Risk communication plays a crucial role in mitigating these risks by addressing risk beliefs in the population and thereby stimulating behavior change. In the synapsis of this project, however, the prevalence of heterogenous prior risk beliefs in different groups of the population were identified as a major challenge for risk communication ...

Design and Implementation of Novel Optical Fabry-Pérot Arrays for Medical Applications
(2024)
Optical sensing systems find a wide range of applications, especially in the medical field, for intelligent, patient-operated health monitoring and early diagnosis, facilitating immediate responses to warnings. Advances in technology have enabled sensors miniaturization with spectrometers using low-cost Fabry-Pérot filters, allowing integration into mobile phones and wearable devices without compromising their resolution. The challenge in filter fabrication is deforming supporting posts deformation during polymer ...

High Consistency Silicone Rubber Foams
(2024-04-23)
Silicone elastomers are high-performance plastics. In the extrusion process, only high-consistency silicone rubbers were used. In order to reduce the cost and weight, silicone rubbers can be foamed during processing. In this study, high-consistency silicone rubber is processed with different physical and chemical blowing agents. The resulting reaction kinetics, as well as the mechanical and morphological properties, had been investigated and compared with each other. This showed that the chemical blowing agent ...

Pathways toward the Use of Non-Destructive Micromagnetic Analysis for Porosity Assessment and Process Parameter Optimization in Additive Manufacturing of 42CrMo4 (AISI 4140)
(2024-02-20)
Laser-based powder bed fusion of metals (PBF-LB/M) is a widely applied additive manufacturing technique. Thus, PBF-LB/M represents a potential candidate for the processing of quenched and tempered (Q&T) steels such as 42CrMo4 (AISI 4140), as these steels are often considered as the material of choice for complex components, e.g., in the toolmaking industry. However, due to the presence of process-induced defects, achieving a high quality of the resulting parts remains challenging in PBF-LB/M. Therefore, an extensive ...

In the Face of Adversity – Conceptual and Empirical Studies on Team and Organizational Resilience
(2024)
In this cumulative dissertation, the resilience of organizational actors is explored through four independent essays. The focus is on investigating why certain organizations and teams are better equipped to handle adversities than others. At the outset of the project, a comprehensive literature review on current research in the field of organizational resilience was conducted. This review enabled the authors to identify the so-called "Building Blocks" of organizational resilience, which provide essential theoretical ...
