  2. 11. Geometrical and percolative properties of spatially correlated models

    Author : Olof Elias; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; continuum percolation; brownian excursions; brownian interlacements; poisson cylinder model; fractal percolation;

    Abstract : This thesis consists of four papers dealing with phase transitions in various models of continuum percolation. These models exhibit complicated dependencies and are generated by different Poisson processes. For each such process there is a parameter, known as the intensity, governing its behavior. READ MORE

  4. 12. Electron Transport and Chaos in Model Mesoscopic Systems

    Author : Thomas Ouchterlony; Hongqi Xu; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis mesoscopic structures intermediate in size between classical macroscopic objects and quantum mechanical objects as atoms are treated. The size of mesoscopic systems are of the same order as the wavelength of the electrons, which makes it necessary to take quantum mechanics into account. READ MORE

  5. 13. Poisson Multi-Bernoulli Mixtures for Multiple Object Tracking

    Author : Yuxuan Xia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian filtering; random finite sets; multi- object tracking; trajectory estimation; extended object; conjugate prior;

    Abstract : Multi-object tracking (MOT) refers to the process of estimating object trajectories of interest based on sequences of noisy sensor measurements obtained from multiple sources. Nowadays, MOT has found applications in numerous areas, including, e.g. READ MORE

  6. 14. Hidden Markov models - Traffic modeling and subspace methods

    Author : Sofia Andersson; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; programming; actuarial mathematics; Statistik; operationsanalys; Statistics; operations research; subspace identification; state space representation; likelihood estimation; Poissonification; traffic analysis; hidden Markov model; Markov-modulated Poisson process; programmering; aktuariematematik;

    Abstract : The main motivation for this thesis, however not the only one, is the search for models for traffic in telecommunication networks. Traffic characterization and modeling are of great importance in the analysis and dimensioning of communication systems. During the last decades we have experienced an explosive growth of our telecommunication networks. READ MORE

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

    Author : Jenny Andersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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
