  1. 1. Semi Markov chain Monte Carlo

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Håkan Ljung; Uppsala universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Adaptive simulation; error-in-the-variables; Kullback-Leibler divergence; Markov chain simulation; Markov chain Monte Carlo; semi-regenerative; MATEMATIK; MATHEMATICS; MATEMATIK; matematisk statistik; Mathematical Statistics;

    Abstract : The first paper introduces a new simulation technique, called semi Markov chain Monte Carlo, suitable for estimating the expectation of a fixed function over a distribution π, Eπf(χ). Given a Markov chain with stationary distribution p, for example a Markov chain corresponding to a Markov chain Monte Carlo algorithm, an embedded Markov renewal process is used to divide the trajectory into different parts.

  2. 2. Monte Carlo Studies of Charge Transport Below the Mobility Edge

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Mattias Jakobsson; Linköpings universitet.; Linköpings universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulation; charge transport; organic materials; conjugated polymers; DNA;

    Abstract : Charge transport below the mobility edge, where the charge carriers are hopping between localized electronic states, is the dominant charge transport mechanism in a wide range of disordered materials. This type of incoherent charge transport is fundamentally different from the coherent charge transport in ordered crystalline materials. READ MORE

  3. 3. Development of New Monte Carlo Methods in Reactor Physics Criticality, Non-Linear Steady-State and Burnup Problems

    University dissertation from Stockholm : Universitetsservice US AB

    Author : Jan Dufek; KTH.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; reactor physics; fission source; inactive cycles; convergence; burnup; steady-state; criticality; eigenvalue; NATURAL SCIENCES Physics Nuclear physics; NATURVETENSKAP Fysik Kärnfysik;

    Abstract : The Monte Carlo method is, practically, the only approach capable of giving detail insight into complex neutron transport problems. In reactor physics, the method has been used mainly for determining the keff in criticality calculations. READ MORE

  4. 4. Accelerating Monte Carlo methods for Bayesian inference in dynamical models

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Johan Dahlin; Linköpings universitet.; Linköpings universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computational statistics; Monte Carlo; Markov chains; Particle filters; Machine learning; Bayesian optimisation; Approximate Bayesian Computations; Gaussian processes; Particle Metropolis-Hastings; Approximate inference; Pseudo-marginal methods;

    Abstract : Making decisions and predictions from noisy observations are two important and challenging problems in many areas of society. Some examples of applications are recommendation systems for online shopping and streaming services, connecting genes with certain diseases and modelling climate change. READ MORE

  5. 5. Charge Transport Simulations for Organic Electronics A Kinetic Monte Carlo Approach

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Riccardo Volpi; Linköpings universitet.; Linköpings universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis we focus on the modelling and simulation of organic electronic devices, investigating their structural and electronic properties. Organic devices have attracted great interest for their innovative properties, but their functioning still represent a theoretical and technological challenge. READ MORE
