The concept of discourse tradition (DT) is a core component of the system of language competence developed by Eugenio Coseriu and unfolds its analytical sharpness embedded in the differentiations of that model. The idea of DT is based on the concepts of historicity, individuality and tradition. A central topic of the debates and controversies that have arisen in Romance linguistics is the question of how historicity and individuality enter into the idea of DT. In comparison, the concept of tradition has been studied ...

Einführung in die moderne rechnerbetonte Statik mit Betonung der wichtigen Rolle, die die Einflussfunktionen für die finiten Elemente bilden, mit Programmen zur Berechnung von Scheiben, Platten und ebenen Rahmen nach der Methode der finiten Elemente und Programmen zur Berechnung von Scheiben, Platten und Laplace-Problemen nach der Methode der Randelemente.

The aim of this thesis is the numerical analysis of nonlinear coupled partial differential equations and their application to ophthalmology. Firstly, we consider fluid-structure interaction problems where the fluid is either Newtonian or viscoelastic. The structure is modelled as a hyperelastic material. The application to ophthalmology lies in the interaction of the vitreous with its surrounding elastic structures like the sclera and the lens. The underlying flow in the vitreous is modelled by a viscoelastic Burgers ...

Die vorliegende Dissertation „Personalentwicklung an Gymnasien und Gemeinschaftsschulen mit Oberstufe in Schleswig-Holstein. Eine empirische Untersuchung aus der Perspektive von Mitgliedern der erweiterten Schulleitung“ wurde im Zeitraum von Oktober 2016 bis Mai 2021 erstellt. Der Startimpuls für diese Arbeit war das Interesse an dem Status quo im Bereich der schulischen Personalentwicklung (PE) im Land Schleswig-Holstein (SH) an Gymnasien (GYM) und Gemeinschaftsschulen mit Oberstufe (GEMOS), d.h., wie schätzen ...

This thesis contributes to the discussion of the utilization of network-supportive flexibility, in particular in the context of local flexibility markets (LFM). The thesis comprises five articles that are methodologically related but can be read independently. The focus of the investigations is on economic aspects and short- and medium-term market processes. Chapter 1 provides an introduction to the topic including the definition of the most important terms. Chapter 2 includes the paper, “Design of regional flexibility ...

In this thesis, a non-linear system of partial differential equations is studied, describing the motions of an elastic structure which is immersed into an incompressible viscous fluid. The displacement of the elastic structure is modelled by a Lamé system and the fluid velocity as well as the fluid pressure are described by the Navier-Stokes equations. The structure and the fluid are coupled via two boundary conditions at the interface which correspond to continuity of velocities and forces. As the elasticity is ...
