16. Recursive black-box identification of nonlinear state-space ODE models
Sammanfattning : Nonlinear system identification methods is a topic that has been gaining interest over the last years. One reason is the many application areas in controller design and system development. However, the problem of modeling nonlinear systems is complex and finding a general method that can be used for many different applications is difficult. LÄS MER
17. Transforming Kiruna : Producing Space, Society, and Legacies of Inequality in the Swedish Ore Fields
Sammanfattning : Extractive resources industries are irreversibly transforming land, air, water, life and society around the world at an unprecedented rate, and Sweden is no exception. This anthropological study analyzes acute issues related to this transformation: the resettlement of six thousand residents of the city of Kiruna due to ground deformations caused by large-scale iron mining by the Swedish state-owned company LKAB (Luossavaara-Kiirunavaara AB).

18. Realistic simulations of delta wing aerodynamics using novel CFD methods
Sammanfattning : The overall goal of the research presented in this thesis is to extend the physical understanding of the unsteady external aerodynamics associated with highly maneuverable delta-wing aircraft by using and developing novel, more efficient computational fluid dynamics (CFD) tools. More specific, the main purpose is to simulate and better understand the basic fluid phenomena, such as vortex breakdown, that limit the performance of delta-wing aircraft. LÄS MER
19. A Methodology for Efficient Conceptual Design Analysis of Nonlinear Dynamic Structural Systems
Sammanfattning : There is a typical requirement conflict between fuel consumption and noise and vibrations in passenger cars. Obviously the combustion engine is a major source of vibration and has an influence on vehicle emissions. Similar properties apply to the power transferring mechanical driveline system. LÄS MER
20. Hidden Markov models - Traffic modeling and subspace methods
Sammanfattning : The main motivation for this thesis, however not the only one, is the search for models for traffic in telecommunication networks. Traffic characterization and modeling are of great importance in the analysis and dimensioning of communication systems. During the last decades we have experienced an explosive growth of our telecommunication networks. LÄS MER
