Factors of Regular Graphs

The main research objective of the present project has been the study of the existence of pairwise disjoint perfect matchings in regular graphs. We prove the existence of highly edge-connected regular graphs which have only „few'' pairwise disjoint perfect matchings.

FOR 5208 - Modelling and simulation of the coupled acoustic, electrical, and thermal dynamics of piezoceramics

The determination of material parameters of piezoceramics for actuator applications by means of an inverse method requires an efficient method for the simulation of the different physical processes in the piezoceramic sample. In addition to the electrostatic equations and acoustic wave propagation, this project focuses on the causal description of ...

FOR 5208: Modelling and simulation of the coupled acoustic, electrical, and thermal dynamics of piezoceramics

Ultrasonic sensors and actuators are used in a wide range of applications in science and technology. In the design and optimization of these components, computer technology is increasingly used. One of the problems in this procedure is the insufficient knowledge of the acoustic or electromechanical material properties of the piezoelectric materials ...

FOR 2863 - Scalable THz Transceiver Impairment Model

Compared to radios operating at purely optical wavelengths or RF/microwave frequencies, the combination of extremely high absolute bandwidths and high relative bandwidths in the THz frequency regime, paired with the severe performance limitations of technologies operating in the so-called "THz-gap", imposes unique challenges on modern digital ...

A two-scale model for damage processes during the machining of carbon fiber reinforced plastics

This project includes an experimental characterization of the carbon-fiber-reinforced plastic (CFK) composite and its components, material modeling, CFK machining tests, and simulation-supported analyses of CFK machining. Its main objective is the simulation-supported prediction of machining damage mechanisms of CFK. Four basic relevant damage ...

Du Châtelet's Philosophie und ihre Beziehung zu Leibniz und Wolff: Übereinstimmungen und Unterschiede – Mercator Fellowship

Das hier vorgeschlagene Projekt will die detaillierte Erforschung von Du Châtelets Verhältnis zu Leibniz und Wolff voranzutreiben. Du Châtelets eigene Referenzen auf Leibniz und Wolff beziehen sich hauptsächlich auf ihre metaphysischen Grundlagen und damit auf einen Kern ihres Werkes, vor allem wenn man dieses aus philosophiegeschichtlicher ...

DemoKult – Die unterrichtsbezogene Förderung von Kompetenzen für eine demokratische Kultur

Nicht nur aufgrund des Angriffskriegs Russlands auf die Ukraine steht das demokratische Selbstverständnis in Europa spürbar unter Druck. Auch nationale Ereignisse (z. B. das Erstarken verfassungsfeindlicher Positionen in Parteien des Bundestags und der Landtage; extremistisch motivierte Anschläge in den letzten Jahren) verdeutlichen, dass ein ...

Covid-19 as amplifier of social inequality- SMall ARea Analyses with German neighborhood Data

In this project we seek to understand the role of disadvantaged neighborhoods with low average socio-economic status of their inhabitants. Individuals in low-income neighborhoods are often assumed to have limited possibilities to avoid contacting people infected with Sars-Cov2. This can be due to bad housing situations (e.g., more individuals live ...
