Sammanfattning : Over the last few decades, congested traffic network have become a seriousproblem in many countries. Congestions result in time losses, increase of fuelconsumption and also raise the risk of accidents. Intelligent transportationsystems may contribute to mitigate such problems. LÄS MER
Sammanfattning : Friction is a phenomenon which is present in most mechanical devices and frequently encountered in everyday life. Noncoercive incremental contact problems with Coulomb friction constitute an important class of friction problems due to their frequent occurrence in mechanical engineering. LÄS MER
Sammanfattning : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). LÄS MER
4. On Ca²+ incorporation and nanoporosity of titanium surfaces and the effect on implant performance
Sammanfattning : Dentala implantat är en väletablerad behandling för att ersätta förlorade tänder med långsiktigt goda resultat. Det finns en uppsjö av implantat med olika ytor på marknaden och bakom dessa ligger stora forskningssatsningar. LÄS MER
Sammanfattning : Rational Krylov methods for model order reduction are studied. A dual rational Arnoldi method for model order reduction and a rational Krylov method for model order reduction and eigenvalue computation have been implemented. It is shown how to deflate redundant or unwanted vectors and how to obtain moment matching. LÄS MER
