  1. 1. Four applications of stochastic processes : Contagious disease, credit risk, gambling and bond portfolios

    Författare :Patrik Andersson; Andreas Nordvall Lagerås; Håkan Andersson; Stewart N. Ethier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stochastic processes; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Sammanfattning : This thesis consists of four papers on applications of stochastic processes. In Paper I we study an open population SIS (Susceptible - Infective - Susceptible) stochastic epidemic model from the time of introduction of the disease, through a possible outbreak and to extinction. The analysis uses coupling arguments and diffusion approximations. LÄS MER

  3. 2. The Passing-On Problem in EU Law Damages and Restitution

    Författare :Magnus Strand; Torbjörn Andersson; Håkan Andersson; Alison Jones; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; EU law; passing-on; private enforcement; damages law; restitution law; indirect purchasers; EU-rätt; övervältring; skadeståndsrätt; restitution; Europarätt; European Integration Law;

    Sammanfattning : In this thesis, the so-called passing-on problem is examined for the purposes of EU law. The passing-on problem may arise when an amount has been charged unlawfully, in whole or in part, and paid by a commercial enterprise. LÄS MER

  4. 3. Error-Correcting Codes Based on Chaotic Dynamical Systems

    Författare :Håkan Andersson; Thomas Mittelholzer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This dissertation treats a novel class of error-correcting codes based on chaotic dynamical systems. The codes are defined over a continuous alphabet whereas the information that is to be transmitted belongs to a discrete set of symbols. Simple expressions can be given for the encoders, and the codewords can be described by a parity-check relation. LÄS MER

  7. 5. A Co-Simulation Approach for Hydraulic Percussion Units

    Författare :Håkan Andersson; Daniel Leidermark; Kjell Simonsson; Daniel Hilding; Mikael Schill; Magnus Eek; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This Licentiate of Engineering thesis concerns modelling and simulation of hydraulic percussion units. These units are often found in equipment for breaking or drilling in rock and concrete, and are also often driven by oil hydraulics, in which complex fluid-structure couplings are essential for their operation.
