  2. 21. Channel Prediction and Target Tracking for Multi-Agent Systems

    Author : Markus Fröhle; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian processes; multitarget tracking; channel prediction; extended target tracking; Multi-agent system; posterior fusion; location uncertainty;

    Abstract : Mobile moving agents as part of a multi-agent system (MAS) utilize the wireless communication channel to disseminate information and to coordinate between each other. This channel is error-prone and the transmission quality depends on the environment as well as on the configuration of the transmitter and the receiver. READ MORE

  4. 22. Modeling of Magnetic Fields and Extended Objects for Localization Applications

    Author : Niklas Wahlström; Fredrik Gustafsson; Thomas B. Schön; Simon Maskell; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localization; magnetic tracking; extended target tracking; signal processing; machine learning; Gaussian processes; deep dynamical model; discretization;

    Abstract : The level of automation in our society is ever increasing. Technologies like self-driving cars, virtual reality, and fully autonomous robots, which all were unimaginable a few decades ago, are realizable today, and will become standard consumer products in the future. READ MORE

  5. 23. Spatial Spread of Organisms : Modeling ecological and epidemiological processes

    Author : Tom Lindström; Uno Wennergren; Colleen Webb; Linköpings universitet; []
    Keywords : Spatial kernel; Spatially explicit modeling; Disease transmission; Animal movements; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis focuses on the spread of organisms in both ecological and epidemiological contexts. In most of the studies presented, displacement is modeled with a spatial kernel function, which is characterized by scale and shape. These are measured by the net squared displacement (or kernel variance) and kurtosis, respectively. READ MORE

  6. 24. Bridges with Random Length and Pinning Point for Modelling the Financial Information

    Author : Mohammed Louriki; Astrid Hilbert; Dorje C. Brody; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brownian motion; Brownian bridge; Gaussian process; Gaussian bridge; Gamma process; Gamma bridge; Lévy process; pinned Lévy process; Markov process; Bayes theorem; stopping time; default time; semi-martingale decomposition; credit risk; defaultable bond; last passage time; enlargement of filtration; stochastic filtering theory; information-based asset pricing; market filtration.; Mathematics; Matematik;

    Abstract : The impact of the information concerning an event of interest occurring at a future random time is the main topic of this work. The event can massively influence financial markets and the problem of modelling the information on the time at which it occurs is of crucial importance in financial modelling. READ MORE

  7. 25. Crossings and maxima in Gaussian fields and seas

    Author : Eva Sjö; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; random waves; extremes; generalised Rice s formula; level-crossings; Gaussian random fields; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : In this thesis the focus is on crossing points in random fields and the probability distributions of various crossing variables in different applications. The crossing points are generalisations to random fields of points of level crossings by stochastic processes. READ MORE
