16. Unsteady Numerical Simulations and Reduced-Order Modelling of Flows around Vehicles
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
17. From cell survival to dose response : modeling biological effects in radiation therapy
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
18. Uncertainty, Robustness and Sensitivity Reduction in the Design of 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
19. Modelling and simulation of simultaneous forming and quenching
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
20. On Control and Estimation of Large and Uncertain Systems
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.
