6. Model Reduction Using Semidefinite Programming
Sammanfattning : In this thesis model reduction methods for linear time invariant systems are investigated. The reduced models are computed using semidefinite programming. Two ways of imposing the stability constraint are considered. However, both approaches add a positivity constraint to the program. LÄS MER
7. Analysis and Optimization of Communication Overheads in Multi-core Architectures
Sammanfattning : The transition to multi-core architectures can be attributed mainly to fundamental limitations in clockfrequency scaling coupled with a slow growth in uniprocessor performance effected by the challengesin exploiting instruction-level parallelism. Consequently, programmers can no longer realize significant performance gains without investing effort into parallelizing applications. LÄS MER
8. Electromagnetic Modeling and Design of Medical Implants and Devices
Sammanfattning : This thesis covers two topics in biomedical electromagnetics: pacemaker lead heating in magnetic resonance imaging (MRI) and optimization of sensorpositions in magnetic tracking.The electromagnetic part of pacemaker lead heating during MRI is a resonant phenomenon which is complicated by, among other factors, the wide range of length scales involved in the problem.

9. Synthesis of a Model-based Tire Slip Controller
Sammanfattning : The Anti-lock Braking System (ABS) is an important component of a complex steering system for the modern car. In the latest generation of brake-by-wire systems, the performance requirements on the ABS have changed. The controllers have to be able to maintain a specified tire slip for each wheel during braking. LÄS MER
10. Wings, turbulent boundary layers and flow separation
Sammanfattning : The present doctoral thesis investigates the turbulent flow developing around wing sections, focusing on the impact of adverse-pressure-gradient (APG) conditions on turbulent boundary layers (TBLs) and the physics of flow separation. Both experimental and numerical methods are employed to generate high-fidelity data sets and provide an in-depth analysis of the flow. LÄS MER
