  1. 1. Modelling the Variability of Bending Strength in Structural Timber - Length and Load Configuration Effects

    Author : Tord Isaksson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; code; reliability-based design; Weibull; test standard; load configuration effect; length effect; weak section; machine grading; visual grading; variability; Structural timber; bending strength; simulation; monte carlo simulation.; Building construction; Byggnadsteknik;

    Abstract : The load carrying capacity of a beam of structural timber is dependent both on the span of the beam and the type of loading. The longer the beam and the more uniform the moment distribution, the lower the load carrying capacity. This phenomenon is due to the variability of material properties within a piece of timber.

  2. 2. Probabilistic System Effects in Timber Structures

    Author : Martin Hansson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

    Abstract : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. READ MORE

  4. 4. On inference in partially observed Markov models using sequential Monte Carlo methods

    Author : Jonas Ströjby; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis concerns estimation in partially observed continuous and discrete time Markov models and focus on both inference about the conditional distribution of the unobserved process as well as parameter inference for the dynamics of the unobserved process. Paper A concerns calibration of advanced stock price models, in particular the Bates and NIG-CIR models, using options data observed through bid-ask spreads. READ MORE

  5. 5. SPECT Imaging using Pinhole Collimation : System Design and Simulation Studies for Pre-Clinical and Clinical Imaging

    Author : Mikael Peterson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pinhole SPECT tomography; Nuclear medicine imaging; Monte Carlo-based image reconstruction;

    Abstract : The focus of this dissertation is the use of pinhole collimation in Nuclear Medicine. A pinhole is a single aperture in an opaque material that is placed between the detector and source of interest, and photons must pass through the hole to reach the detector. The choices of pinhole parameters, e.g. READ MORE
