Sammanfattning : This thesis focuses on the problem of estimating parameters in bilinear and trilinear regression models in which random errors are normally distributed. In these models the covariance matrix has a Kronecker product structure and some factor matrices may be linearly structured. LÄS MER
Sammanfattning : This thesis is concerned with parameter estimation, signal processing, and applications. In the first part, imaging using radar is considered. More specifically, two methods are presented for estimation and removal of ground-surface reflections in ground penetrating radar which otherwise hinder reliable detection of shallowly buried landmines.

3. Spatial Statistics and Ancestral Recombination Graphs with Applications in Gene Mapping and Geostatistics
Sammanfattning : This thesis explores models and algorithms in geostatistics and gene mapping. The first part deals with the use of computationally effective lattice models for inference of data with a continuous spatial index. LÄS MER
Sammanfattning : This thesis focuses on the problem of estimating parameters in multivariate linear models where particularly the mean has a bilinear structure and the covariance matrix has a linear structure. Most of techniques in statistical modeling rely on the assumption that data were generated from the normal distribution. LÄS MER
Sammanfattning : Multicomponent superconductors described by several complex matter fields have properties radically different from those of their single-component counterparts. Examples include partially ordered phases and spontaneous breaking of time-reversal symmetry due to frustration between Josephson-coupled components. LÄS MER
