  3. 2. Local Influence Analysis and Cross-over Studies

    Författare :Chengcheng Hao; Tatjana von Rosen; Dietrich von Rosen; Thomas Holgersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Delta-beta-based local influence; Explicit maximum likelihood estimate; Influential observation; Mixed linear model; Perturbation scheme; Statistical diagnostics; Statistics; statistik;

    Sammanfattning : With a special reference to cross-over design models with random individual effects, the purpose of this dissertation is to develop new methodology to detect influential observations in the context of mixed linear models with explicit maximum likelihood estimators (MLEs).Case-weighted perturbation schemes within and between subjects in mixed models are constructed.

  5. 4. Relaxation dynamics of perturbed water and other H-bonded liquids

    Författare :Johan Sjöström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; confinement; supercooled water; dielectric relaxation; mixtures;

    Sammanfattning : Most liquids can be supercooled below its melting point where the dynamics dramatically slows down with decreasing temperature until the material appears solid on the experimental time scale and becomes stuck in an out-of-equilibrium configuration, a glass. Water, one of the most abundant substances on earth, is no exception. LÄS MER

  7. 5. Crystallographic Aspects of Protein Phasing at Very Low Resolution

    Författare :Klas Andersson; Jens Nyborg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Sammanfattning : A protein crystallographic method for obtaining structure factor phases of low-order reflections is presented. It is based on four observations: 1) The electron density inside proteins is relatively smooth and uniform at low resolution. LÄS MER
