  1. 6. Defining and applying surrogate safety measures and behavioural indicators through site-based observations

    Författare :Tim de Ceunynck; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surrogate safety measures; behavioural indicators; traffic safety; site-based observations; traffic conflicts; traffic conflict techniques; road user interactions;

    Sammanfattning : This dissertation looks into surrogate safety measures and behavioural indicators that are collected through site-based observations. Surrogate safety measures are defined as measurements that are used to describe the relationship between two road users in a traffic event for the purpose of quantifying the crash probability and/or the potential crash severity in a meaningful way.

  3. 7. Design and Optimization under Uncertainties : A Simulation and Surrogate Model Based Approach

    Författare :Johan Persson; Johan Ölvander; David Aspenberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis deals with development of complex products via modeling and simulation, and especially the use of surrogate models to decrease the computational efforts when probabilistic optimizations are performed. Many methods that can be used to perform probabilistic optimizations exist and this thesis strives to present and demonstrate the capabilities of a few of them. LÄS MER

  4. 8. Optimization of Castings by using Surrogate Models

    Författare :Erik Gustafsson; Niclas Strömberg; Bo Torstenfelt; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Response Surface Methodology RSM ; Residual Stresses; Castings; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : In this thesis structural optimization of castings and thermomechanical analysis of castings are studied.In paper I an optimization algorithm is created by using Matlab. The algorithm is linked to the commercial FE solver Abaqus by using Python script. LÄS MER

  5. 9. A Study of the Surrogate Light chain

    Författare :Annica Mårtensson; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunologi; transplantation; serology; Immunology; VpreB; lambda 5; transcription; B cell development; serologi;

    Sammanfattning : This thesis has investigated the importance of the VpreB1 protein in early B cell development. Mice lacking the VpreB1 protein showed normal numbers of peripheral mature B cells. LÄS MER

  7. 10. Efficient Optimization of Complex Products : A Simulation and Surrogate Model Based Approach

    Författare :Johan Persson; Johan Ölvander; Petter Krus; Hirpa G. Lemu; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis investigates how to use optimization efficiently when complex products are developed. Modelling and simulation are necessary to enable optimization of products, but here it is assumed that verified and validated models of the products and their subsystems are available for the optimization.
