6. Foundation of Density Functionals in the Presence of Magnetic Field
Sammanfattning : This thesis contains four articles related to mathematical aspects of Density Functional Theory.In Paper A, the theoretical justification of density methods formulated with current densities is addressed. It is shown that the set of ground-states is determined by the ensemble-representable particle and paramagnetic current density. LÄS MER
7. Immunological consequences of Epstein-Barr virus replication
Sammanfattning : Epstein-Barr virus (EBV) is a ubiquitous human herpesvirus involved in the pathogenesis of a wide spectrum of malignant and non-malignant diseases. In healthy EBV carriers, the virus is believed to infect two major cellular targets - B lymphocytes and epithelial cells. LÄS MER
8. Indexing strategies for time series data
Sammanfattning : Traditionally, databases have stored textual data and have been used to store administrative information. The computers used. and more specifically the storage available, have been neither large enough nor fast enough to allow databases to be used for more technical applications. LÄS MER
9. Micromechanical modeling of cleavage fracture in polycrystalline materials
Sammanfattning : Cleavage fracture in ferritic steels can be defined as a sequence of few critical steps. At first nucleation of a microcrack takes place, often in a hard inclusion. This microcrack then propagates into the surrounding matrix material. The last obstacle before failure is the encounter of grain boundaries. LÄS MER
10. Fundamentals of High Power Impulse Magnetron Sputtering
Sammanfattning : In plasma assisted thin film growth, control over the energy and direction of the incoming species is desired. If the growth species are ionized this can be achieved by the use of a substrate bias or a magnetic field. Ions may be accelerated by an applied potential, whereas neutral particles may not. LÄS MER
