Adaptive Dynamic Programming: Solltrajektorienfolgeregelung und Konvergenzbedingungen
(2022)
In this work, discrete-time and continuous-time methods that integrate flexible reference trajectory representations into Adaptive Dynamic Programming approaches are presented and analyzed for the first time. Moreover, ...
Implicit Incremental Model Analyses and Transformations
(2021)
When models of a system change, analyses based on them have to be reevaluated in order for the results to stay meaningful. In many cases, the time to get updated analysis results is critical. This thesis proposes multiple, ...
Entwicklung und Evaluierung einer Kommunikationsgestützten Lokalisierung
(2023)
The content of this work is the development of a localization system, which enables several driverless transport vehicles to navigate locally in a highly flexible and free way. The ceiling mounted sensor system detects and ...
Wirksamkeit der Taktplanung aus Perspektive des Bauherrn am Beispiel von Produktionsimmobilien in der Automobilindustrie
(2022)
This work analyses the time effect that occurs due to the use of takt planning and takt control during the construction process from the perspective of the client. At first the historical courses of takt planning and takt ...
Modeling martensitic phase transformation in dual phase steels based on a sharp interface theory
(2021)
Martensite forms under rapid cooling of austenitic grains accompanied by a change of the crystal lattice. Large deformations are induced which lead to plastic dislocations. In this work a transformation model based on the ...
Gamification of telematics data to enhance operators’ behaviour for improvement of machine productivity in loading cycles
(2023)
Construction industry is suffering from low productivity rate in various projects such as excavation. Although this issue is discussed in literature and several approaches are proposed to address it, productivity rate is ...

(2023)
Digitalization has already transformed many areas of the economy and social life. Aspects of healthcare and clinical practice are also undergoing digital transformation. In light of these developments, this dissertation ...
Deep Reinforcement Learning zur Steigerung von Energieeffizienz und Pünktlichkeit von Straßenbahnen
(2023)
This work investigates how the energy efficiency and punctuality of streetcars can be increased by using AI. The AI is trained on two scenarios at three traffic times each. The determined driving profiles are compared with ...
Dynamic Model-based Analysis of Oxygen Reduction Reaction in Gas Diffusion Electrodes
(2024)
In this work, the first simulation model of oxygen depolarized cathodes (ODC), which are silver catalyst-based gas diffusion electrodes, is presented that considers the phase equilibrium of the gas-liquid interface and ...
Die Baugeschichte des Freiburger Münsterturms
(2023)
The Freiburg Minster spire viewed from the perspective of archaeological building research. Individual building phases of the tower are presented by means of collecting and analysing thousands of stonemason's marks appearing ...
Ganzheitliche Optimierung einer Axialkolbenpumpe durch bedarfsangepasste Entlastung tribologischer Kontakte
(2022)
Swash plate axial piston pumps are used in various industrial & mobile applications. An optimization of this displacement principle can be achieved by the active influence of the hydrostatic relief in tribological contacts.The ...
Fundamentals for the Dimensioning and Optimization of Prestressed Segmented Girders for Application in Bridge Crane Systems
(2022)
Bridge cranes are widely used as discontinuous material handling systems in industrial environments. The so-called crane bridge plays a central role in the overall construction. With increasing span widths and load capacities, ...
Fluorescent thermal imaging method for investigating transient effects in high-temperature superconductor tapes and coils
(2022)
This work presents the development and application of high-speed fluorescent thermal imaging for quench analysis in high-temperature superconductors (HTS). Using a fluorescent coating, with a temperature-dependent light ...
