    Sammanfattning : In the modern practice, a sustainable development strategy in a domain of wasteutilization is shifting its focus from a general completeness of recycling to a morespecific attention to efficiently utilize elements in the wastes. This is well-illustrated bythe steelmaking slag industries. LÄS MER

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

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Jenny Andersson; Göteborgs universitet.; Gothenburg University.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Poisson process; Convex sets; Material fatigue; Voronoi tessellation; Germ-grain process; Pair-correlation function; Mark-correlation function; Short cracks; Volume fraction;

    Sammanfattning : 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. LÄS MER
