21. Essays on nonlinear time series modelling och hypothesis testing
Sammanfattning : There seems to be a common understanding nowadays that the economy is nonlinear. Economic theory suggests features that can not be incorporated into linear frameworks, and over the decades a solid body of empirical evidence of nonlinearities in economic time series has been gathered.

22. Analysis of Lateral Transshipments in Inventory Systems
Sammanfattning : This thesis is based on two scientific papers. In these papers we study how one can approximate the inventory level of probabilities and the transshipment rates for inventory systems that apply lateral transshipment policies. LÄS MER
23. Issues in the Design and Analysis of Dependable Distributed Real-Time Systems
Sammanfattning : The importance of computer system dependability is increasing as safety-critical control systems are becoming more prevalent. As an example, the techniques and concepts used in present-day fly-by-wire aircraft can be expected to be introduced in tomorrow's automobiles. LÄS MER
24. Iterative solution of Maxwell's equations in frequency domain
Sammanfattning : We have developed an iterative solver for the Moment Method. It computes a matrix–vector product with the multilevel Fast Multipole Method, which makes the method scale with the number of unknowns. The iterative solver is of Block Quasi-Minimum Residual type and can handle several right-hand sides at once. LÄS MER
25. Microwave Gas and Multipactor Breakdown in Inhomogeneous Fields
Sammanfattning : Microwave gas and multipactor breakdown remains to be one of the limiting factors for the maximum power in microwave devices. Above a certain electric field strength, the so-called breakdown threshold, free electrons can multiply by making ionizing impacts with neutral gas molecules, or causing secondary emission upon impact with system surfaces.
