  1. 1. Inferring evolution in bacteria using Markov chains and genomic signatures

    Författare :Daniel Dalevi; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Prediction suffix tree; Markov chains; Molecular evolution; Bioinformatics; Gene order rearrangements; Horizontal gene transfer; Variable length Markov chains;

    Sammanfattning : This thesis concerns the development of methods and models in evolutionary molecular biology. The techniques are also applicable to other similar biological problems. The first contribution is a novel classifier using fixed and variable length Markov chains that can discriminate between bacterial DNA of different species. LÄS MER

  2. 2. Rainflow Analysis of Switching Markov Loads

    Detta är en avhandling från Mathematical Statistics, Centre for Mathematical Sciences, Lund University

    Författare :Pär Johannesson; Lunds universitet.; Lund University.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; programming; operations research; Statistics; rainflow matrix; fatigue; vehicle load; hidden Markov model; random load; Markov model; Switching process; Statistik; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : Rainflow cycles are often used in fatigue analysis of materials for describing the variability of applied loads. Therefore, an important characteristic of a random load process is the intensity of rainflow cycles, also called the expected rainflow matrix (RFM), which can be used for evaluation of the fatigue life.

  4. 4. Markov Chains, Renewal, Branching and Coalescent Processes Four Topics in Probability Theory

    Detta är en avhandling från Stockholm : Matematiska institutionen

    Författare :Andreas Nordvall Lagerås; Stockholms universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Sammanfattning : This thesis consists of four papers.In paper 1, we prove central limit theorems for Markov chains under (local) contraction conditions. As a corollary we obtain a central limit theorem for Markov chains associated with iterated function systems with contractive maps and place-dependent Dini-continuous probabilities. LÄS MER

  5. 5. Particle filters and Markov chains for learning of dynamical systems

    Detta är en avhandling från Linköping University Electronic Press

    Författare :Fredrik Lindsten; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bayesian learning; System identification; Sequential Monte Carlo; Markov chain Monte Carlo; Particle MCMC; Particle filters; Particle smoothers;

    Sammanfattning : Sequential Monte Carlo (SMC) and Markov chain Monte Carlo (MCMC) methods provide computational tools for systematic inference and learning in complex dynamical systems, such as nonlinear and non-Gaussian state-space models. This thesis builds upon several methodological advances within these classes of Monte Carlo methods. LÄS MER
