  1. 1. Non-overlapping Germ-grain Models: Characteristics and Material Modelling

    Author : Jenny Andersson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Poisson process; Convex sets; Material fatigue; Voronoi tessellation; Germ-grain process; Pair-correlation function; Mark-correlation function; Short cracks; Volume fraction; Germ-grain process;

    Abstract : We consider three different non--overlapping germ--grain models, two of which are constructed in a similar fashion. These two models are generalisations of Mat\'ern's hard--core models. In both cases we start with a homogeneous Poisson process and use the points as centres of convex sets, grains, of the same shape. READ MORE

    Abstract : The topic of this Thesis is magnetization dynamics on atomic length scales. A computational scheme, Atomistic Spin Dynamics, based on density functional theory, the adiabatic approximation and the atomic moment approximation is presented. READ MORE

  3. 3. On the Phase Behaviour of Soft Matter: Understanding Complex Interactions via Quantitative Imaging

    Author : Maxime Bergman; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microgels; Lysozyme; eye lens proteins; confocal microscopy; interaction potential; phase behaviour; simulations;

    Abstract : The effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. READ MORE
