Methode zur Messung des Einflusses von Lichtimpulsen auf die visuelle Leistungsfähigkeit
(2021)
Due to its dynamic range, the human eye can adapt to a wide variety of light situations within a very short time. If the dynamic range of the eye is insufficient, glare occurs. There is no suitable objective measurement ...
Anonymous Point Collection - Improved Models and Security Definitions
(2020)
This work is a comprehensive, formal treatment of anonymous point collection. The proposed definition does not only provide a strong notion of security and privacy, but also covers features which are important for practical ...
Experimentelle Untersuchung der Zündung von Kerosin Jet A-1 unter subatmosphärischen Bedingungen
(2024)
The present study investigates the generation of a flame kernel in the polydisperse spray of a complex fuel under the influence of turbulent flow and under subatmospheric conditions in order to contribute to a better ...
Mechanische und Strömungsmechanische Topologieoptimierung mit der Phasenfeldmethode
(2022)
In engineering work, the optimization of the microstructure of a material, of mechanically loaded components and of components influencing the flow behaviour is important. Understanding the behavior of flows in geological ...
Modellierung von Lithium-Ionen-Batterien zur Lebensdauerprädiktion unter besonderer Berücksichtigung des Anodenüberhangeffekts
(2022)
The focus of this work is on the modelling of the degradation behaviour of conventional lithium-ion cells with graphite/NMC electrodes in conjunction with electrolytes based on LiPF6 in organic solvents. The potential for ...
Entwicklung eines lichtbasierten Fahrerassistenzsystems
(2020)
In this work describes the development of a light-based driver assistance system through projections on the road. Under realistic conditions it is shown that information can be transmitted to the driver at night by using ...
On the Influence of Piecewise Defined Contact Geometries on Friction Dampers
(2023)
This work considers dampers that do not solely focus on a single strategy but instead combine them. The capabilities of conventional dry friction dampers are expanded by taking into account piecewise defined contact ...
