  1. 6. Foundation of Density Functionals in the Presence of Magnetic Field

    Författare :Andre Laestadius; Michael Benedicks; Trygve Helgaker; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Current density functional theory; Hohenberg-Kohn theorems; paramagnetic current density functionals; Kohn-Sham theory; Levy-Lieb functional; variational principle; N-representable; degeneracy; Mathematics; Matematik;

    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

  2. 7. Immunological consequences of Epstein-Barr virus replication

    Författare :Andre Ortlieb Guerreiro Cacais; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    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

  3. 8. Indexing strategies for time series data

    Författare :Henrik André-Jönsson; Nahid Shahmehri; Patrick Lambrix; Tore Risch; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    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

  4. 9. Micromechanical modeling of cleavage fracture in polycrystalline materials

    Författare :Mateusz Stec; Jonas Faleskog; Andre Pineau; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cleavage fracture; probabilistic modeling; brittle to ductile transition; cohesive zone; visco-plastic material; Engineering mechanics; Teknisk mekanik; Other technology; Övriga teknikvetenskaper;

    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

  5. 10. Fundamentals of High Power Impulse Magnetron Sputtering

    Författare :Johan Böhlmark; Ulf Helmersson; André Anders; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma; Pulsed plasma; High Power Pulsed Magnetron Sputtering; Plasma Characterization; Physics; Fysik;

    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
