  1. 1. Bayesian networks: exact inference and applications in forensic statistics

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Ivar Simonsson; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian networks; variable elimination algorithm; forensic statistics; relationship inference; mutation models; relationship inference; variable elimination algorithm; forensic statistics; mutation models;

    Abstract : Exact inference on Bayesian networks has been developed through sophisticated algorithms. One of which, the variable elimination algorithm, identifies smaller components of the network, called factors, on which local operations are performed. In principle this algorithm can be used on any Bayesian network. READ MORE

  2. 2. Physiologically based pharmacokinetic modeling in risk assessment - Development of Bayesian population methods

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fredrik Jonsson; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; methyl chloride; dichloromethane; toluene; styrene; uncertainty; intra- individual variability; risk assessment; physiologically based modeling; Markov chain Monte Carlo; PBPK; Bayesian; population modeling; Farmaceutisk biovetenskap; PHARMACY Biopharmacy; FARMACI Biofarmaci; Biopharmaceutics; biofarmaci;

    Abstract : In risk assessment of risk chemicals, variability in susceptibility in the population is an important aspect. The health hazard of a pollutant is related to the internal exposure to the chemical, i.e. the target dose, rather than the external exposure. READ MORE

  3. 3. Bayesian Phylogenetic Inference

    University dissertation from Stockholm University

    Author : Sebastian Höhna; Tom Britton; Fredrik Ronquist; Lars Arvestad; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis we consider two very different topics in Bayesian phylogenetic inference. The first paper, "Inferring speciation and extinction rates under different sampling schemes" by Sebastian Höhna, Tanja Stadler, Fredrik Ronquist and Tom Britton, focuses on estimating the rates of speciation and extinction of species when only a subsample of the present day species is available.

  4. 4. Recursive Bayesian Estimation : Navigation and Tracking Applications

    University dissertation from Linköping : Linköping University

    Author : Niclas Bergman; Fredrik Gustafsson; Lennart Ljung; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Target tracking; Autonomous aircraft navigation; Terrain navigation;

    Abstract : Recursive estimation deals with the problem of extracting information about parameters, or states, of a dynamical system in real time, given noisy measurements of the system output. Recursive estimation plays a central role in many applications of signal processing, system identification and automatic control. READ MORE

  5. 5. Assesing performance of PCR analysis using Bayesian modelling

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Ronny Hedell; Göteborgs universitet.; Gothenburg University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian; Hierarchical model; PCR; Low-template DNA; Bacillus anthracis; Sensitivity; Forensic science; Forensic science; Bacillus anthracis; Low-template DNA; PCR; Hierarchical model; Sensitivity;

    Abstract : Different analytical methods are available to analyse the DNA samples from crime scenes or to screen samples for the presence of some target bacterium. For this purpose a method known as Polymerase Chain Reaction (PCR) can often be used. READ MORE
