  1. 16. Small Cohort Population Forecasting via Bayesian Learning

    University essay from KTH/Matematisk statistik

    Author : Simon Vallin; [2017]
    Keywords : ;

    Abstract : A set of distributional assumptions regarding the demographic processes of birth, death, emigration and immigration have been assembled to form a probabilistic model framework of population dynamics. This framework was summarized as a Bayesian network and Bayesian inference techniques are exploited to infer the posterior distributions of the model parameters from observed data. READ MORE

  3. 17. Monte Carlo Simulations for Chemical Systems

    University essay from Linköpings universitet/Matematiska institutionen; Linköpings universitet/Tekniska fakulteten

    Author : Karl Rönnby; [2016]
    Keywords : Monte Carlo; Markov chain Monte Carlo; Metropolis algorith; Kinetic Monte Carlo; ilicon Carbide.;

    Abstract : This thesis investigates dierent types of Monte Carlo estimators for use in computationof chemical system, mainly to be used in calculating surface growthand evolution of SiC. Monte Carlo methods are a class of algorithms using randomsampling to numerical solve problems and are used in many cases. READ MORE

  4. 18. Bayesian parameter estimation in Ecolego using an adaptive Metropolis-Hastings-within-Gibbs algorithm

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Sverrir Þorgeirsson; [2016]
    Keywords : ;

    Abstract : Ecolego is scientific software that can be used to model diverse systems within fields such as radioecology and pharmacokinetics. The purpose of this research is to develop an algorithm for estimating the probability density functions of unknown parameters of Ecolego models. READ MORE

  5. 19. Magnetic Monopole Current in Artificial Square Spin Ice

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oscar Eriksson; Kaj Dahl; [2014]
    Keywords : ;

    Abstract : Recent theoretical and experimental results have revealed the existence of magnetic monopoles, in the form of quasi particles, in both condensed matter known as spin ice, as well as in two-dimensional artificial versions of the same material. In this report a two-dimensional Ising model is first examined, then an artificial square spin ice model using a dipole approximation, only taking into account nearest and next nearest neighbors.

  6. 20. Study of Magnetic Nanostructures using Micromagnetic Simulations and Monte Carlo Methods

    University essay from Uppsala universitet/Materialfysik

    Author : Nils Bäckström; Jonathan Löfgren; Vilhelm Rydén; [2014]
    Keywords : frustration; magnets; spin ice; hysteresis; monte carlo; simulation; vortex; micromagnetics; metropolis;

    Abstract : We perform micromagnetic simulations in MuMax3 on various magneticnanostructures to study their magnetic state and response to external fields. Theinteraction and ordering of nanomagnetic arrays is investigated by calculating themagnetostatic energies for various configurations. READ MORE
