11. Schools in sparse spatial structures
Sammanfattning : This thesis describes and analyses how the school sector in sparsely populated municipalities in northern Sweden has developed with emphasis on spatial dimensions and in relation to demographic change and political reforms during the last 20 years.In paper I primary schools were studied in a number of small municipalities in the northern parts of Norway, Sweden, and Finland.

13. Krylov Subspace Methods for Linear Systems, Eigenvalues and Model Order Reduction
Sammanfattning : New variants of Krylov subspace methods for numerical solution of linear systems, eigenvalue, and model order reduction problems are described. A new method to solve linear systems of equations with several right-hand sides is described. LÄS MER
14. Estimation for Sensor Fusion and Sparse Signal Processing
Sammanfattning : Progressive developments in computing and sensor technologies during the past decades have enabled the formulation of increasingly advanced problems in statistical inference and signal processing. The thesis is concerned with statistical estimation methods, and is divided into three parts with focus on two different areas: sensor fusion and sparse signal processing. LÄS MER
15. Sparse Modeling Heuristics for Parameter Estimation - Applications in Statistical Signal Processing
Sammanfattning : This thesis examines sparse statistical modeling on a range of applications in audio modeling, audio localizations, DNA sequencing, and spectroscopy. In the examined cases, the resulting estimation problems are computationally cumbersome, both as one often suffers from a lack of model order knowledge for this form of problems, but also due to the high dimensionality of the parameter spaces, which typically also yield optimization problems with numerous local minima.
