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

    Författare :Mattias Jakobsson; Sven Stafström; Patrick Norman; Jérôme Cornil; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulation; charge transport; organic materials; conjugated polymers; DNA;

    Sammanfattning : 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. LÄS MER

  3. 2. Charge Transport Simulations for Organic Electronics : A Kinetic Monte Carlo Approach

    Författare :Riccardo Volpi; Mathieu Linares; Sven Stafström; Martijn Kemerink; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  4. 3. Development of Experimental Brachytherapy Dosimetry Using Monte Carlo Simulations for Detector Characterization

    Författare :Vaiva Kaveckyte; Åsa Carlsson Tedgren; Alexandr Malusek; Hamza Benmakhlouf; Jan Seuntjens; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dosimetry; brachytherapy; solid-state detectors; Monte Carlo;

    Sammanfattning : Brachytherapy (BT) is a type of interventional radiotherapy that is advantageous due to high absorbed dose conformity and possibility to deliver high dose in few fractions. It is often used for prostate and gynecological tumors as monotherapy or a boost alongside external beam radiotherapy (EBRT). LÄS MER

  5. 4. Machine learning using approximate inference : Variational and sequential Monte Carlo methods

    Författare :Christian Andersson Naesseth; Thomas Schön; Fredrik Lindsten; Iain Murray; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Automatic decision making and pattern recognition under uncertainty are difficult tasks that are ubiquitous in our everyday life. The systems we design, and technology we develop, requires us to coherently represent and work with uncertainty in data. LÄS MER

  7. 5. Sequential Monte Carlo Filters and Integrated Navigation

    Författare :Per-Johan Nordlund; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis we consider recursive Bayesian estimation in general, and sequential Monte Carlo filters in particular, applied to integrated navigation. Based on a large number of simulations of the model, the sequential Monte Carlo filter, also referred to as particle filter, provides an empirical estimate of the full posterior probability density of the system.
