Modeling of plasticity at large strains

This thesis is concerned with various aspects of the constitutive modeling of plasticity. Both theoretical issues and issues related to the numerical implementation of the constitutive models are addressed. An approach to the modeling of kinematic hardening plasticity when large strains are present, taking the microstructure into account, is developed. Kinematic hardening is modeled using a varia

Abstract in DanishIt is the aim of this article to show how some cancer patients get caught in the so called welfare system of Denmark, simply because they have become too physically and/or mentally ill to meet the legal requirements of employment. Based on sociological analysis of a number of interviews, three cases are constructed. The analyses only take a user perspective. They show how, depend

Prohibition:negative imperatives and the parametric typology of negation

A number of researchers have offered hypotheses about the syntactic relationship between Tense and Negation. Zanuttini 1996, for example, has argued that the head NEG may only occur in the presence of Tense. This paper examines data on negation in 15 languages which has been collected in an ongoing typological research project, PARATYP. The study focuses on the difference between prohibitive and n

Exploring the interactome of EF-hand proteins

EF-hand proteins are central in many cellular processes being the main group of Ca2+-sensing and buffering proteins in the cell. In the work presented in this thesis we study ligand interactions of three EF-hand proteins; calmodulin, calbindin D28k and secretagogin. We have developed a screening method using proteins arrays and validation of targets with surface plasmon resonance. With have applie

Interarrival time distribution for a non-Markovian arrival process

We consider a probabilistic model for workload input into a telecommunication system. It captures the dynamics of packet generation in data traffic as well as accounting for long-range dependence and self-similarity exhibited by real traces. The workload has stationary increments as observed in high-speed data networks for certain periods. Such periods with peak demand can be studied with this mod
