  1. 16. Unsteady Numerical Simulations and Reduced-Order Modelling of Flows around Vehicles

    Författare :Jan Östh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reduced-Order Modelling; Numerical Simulations; Large Eddy Simulation; Vehicle Aerodynamics;

    Sammanfattning : In this thesis several simulations have been carried out aimed at improving the knowledge of vehicle aerodynamics and improving the flow around vehicles with respect to theaerodynamic drag. Five flows around different simplified vehicle models have been considered in five appended publications. LÄS MER

  3. 17. From cell survival to dose response : modeling biological effects in radiation therapy

    Författare :Minna Wedenberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Radiobiological models;

    Sammanfattning : The main goal in curative radiation therapy is to eradicate the tumor while minimizing radiation-induced damage to normal tissue. Ions, including protons and carbon ions, are increasingly being used for cancer treatment. LÄS MER

  4. 18. Uncertainty, Robustness and Sensitivity Reduction in the Design of Single Input Control Systems

    Författare :Kjell Nordström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty; Robustness; Sensitivity; Single input control systems;

    Sammanfattning : Feedback control of systems modelled as single input, time invariant, linear and continuous time systems is the subject of this thesis. A growing interest in the design of feedback control systems that can cope with model uncertainties has been the motivation for the study. LÄS MER

  5. 19. Modelling and simulation of simultaneous forming and quenching

    Författare :Greger Bergman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : The objective of this thesis is to develop and evaluate numerical methods for modelling and simulation of simultaneous forming and quenching within an integrated product development environment. Simultaneous forming and quenching, also referred to as hot-stamping, is a manufacturing process for high strength automotive components such as side impact protection beams. LÄS MER

  7. 20. On Control and Estimation of Large and Uncertain Systems

    Författare :Olle Kjellqvist; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis contains an introduction and six papers about the control and estimation of large and uncertain systems. The first paper poses and solves a deterministic version of the multiple-model estimation problem for finite sets of linear systems. The estimate is an interpolation of Kalman filter estimates.
