  1. 1. Dynamic Train-Track Interaction: Linear and Non-Linear Track Models with Property Scatter

    Författare :Johan Oscarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic track properties; non-linear track properties; dynamic train-track interaction; Latin Hypercube; perturbation technique; full-scale and laboratory measurements;

    Sammanfattning : A numerical method was developed to investigate the vertical dynamic behaviour of a railway track subjected to the loading of a moving train. The numerical simulations are carried out in the time-domain with what is known as a moving mass model. LÄS MER

  3. 2. Probabilistic Analysis and Reliability of Engineering Structures

    Författare :Anders Olsson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; roof truss; racking system; importance sampling; Latin hypercube sampling; reliability;

    Sammanfattning : This thesis, consisting of six papers, concerns methods for probabilistic analysis of engineering structures. The work comprises evaluations of available methods, developments of new and improved methods, and applications of probabilistic analysis to engineering structures. LÄS MER

  4. 3. Estimating Probability Distribution by doing Computer Experiments

    Författare :Gunnar Kjell; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer simulations; seismic verification; response spectrum prediction; stratified sampling; latin hypercube sampling; variance reduction; variance estimation; seismic verification;

    Sammanfattning : In almost every field of engineering, advanced computer programs are used. In many cases only the probability distributions of the input variables to the programs are known. Sometimes stochastic processes are used as input, for example if the stresses in a construction due to an earthquake are to be calculated. LÄS MER

  5. 4. Uncertainty and Sensitivity Analysis Applied to the Validation of BWR Bundle Thermal-Hydraulic Calculations

    Författare :Augusto Hernandéz Solís; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Latin Hypercube sampling; uncertainty and sensitivity analysis; Thermal‐hydraulic codes; simple random sampling; reactor safety analysis; BFBT benchmark;

    Sammanfattning : In recent years, more realistic safety analyses of nuclear reactors have been based on best estimate (BE) computercodes. The need to validate and refine BE codes that are used in the predictions of relevant reactor safetyparameters, led to the organization of international benchmarks based on high quality experimental data.
