  1. 1. Experiments on oblique transition in wall bounded shear flows

    Författare :Per Elofsson; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis considers laminar-turbulent transition in wall bounded shear flows, with a focus on transition emanating from a pair of oblique disturbance waves. The oblique waves interact nonlinearly and transfers disturbance energy into streamwise vortices, which generate streamwise streaks through a linear mechanism that operates also at conditions where stability theory predicts decay of all eigenmodes.

  3. 2. Prediction, modeling, and refinement of protein structure

    Författare :Per Larsson; Arne Elofsson; Erik Lindahl; Barry Honig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein structure prediction; Multiple alignments; Quality assessment; Molecular dynamics; Implicit solvent; Refinement; Bioinformatics; Bioinformatik; Bioinformatics; Bioinformatik; Statistical mechanics; Statistisk mekanik; Biochemistry; biokemi;

    Sammanfattning : Accurate predictions of protein structure are important for understanding many processes in cells. The interactions that govern protein folding and structure are complex, and still far from completely understood. However, progress is being made in many areas. Here, efforts to improve the overall quality of protein structure models are described. LÄS MER

  4. 3. Thin Film Growth using Pulsed and Highly Ionized Vapor Fluxes

    Författare :Viktor Elofsson; Kostas Sarakinos; Jones Alami; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Microstructure and morphology of thin films are decisive for many of their resulting properties. To be able to tailor these properties, and thus the film functionality, a fundamental understanding of thin film growth needs to be acquired. LÄS MER

  5. 4. Domain rearrangement and creation in protein evolution

    Författare :Diana Ekman; Arne Elofsson; Christine Orengo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinformatics; Bioinformatik; Biochemistry; biokemi;

    Sammanfattning : Proteins are composed of domains, recurrent protein fragments with distinct structure, function and evolutionary history. Some domains exist only as single domain proteins, however, a majority of them are also combined with other domains. LÄS MER
