1. Some Investigations into the Class of Exponential Power Distributions
Sammanfattning : In this thesis, methods are developed relating to the exponential power class of distributions.Paper I considers Bayesian linear mixed models where the usual normality assumption is replaced by the multivariate exponential power distribution. Particular focus lies on Bayesian testing of the fixed effects. LÄS MER
2. Exponential integrators for stochastic partial differential equations
Sammanfattning : Stochastic partial differential equations (SPDEs) have during the past decades become an important tool for modeling systems which are influenced by randomness. Because of the complex nature of SPDEs, knowledge of efficient numerical methods with good convergence and geometric properties is of considerable importance. LÄS MER
3. Approximation with interpolating exponential sums
Sammanfattning : .... LÄS MER
4. Efficient Use of Exponential Size Linear Programs
Sammanfattning : In the past decades, linear programming (LP) has been successfully used to develop approximation algorithms for various optimization problems. In particular, the so-called assignment LP has lead to substantial progress for various allocation problems, including scheduling unrelated parallel machines. LÄS MER
5. Extension of separately analytic functions and applications to mathematical tomography : characterizing the range of the exponential Radon transform
Sammanfattning : The principal problem that is dealt with in the thesis is to characterize the range of the exponential Radon transform for both constant attenuation and angle dependent attenuation (in the latter case we assume that the attenuation is a trigonometric polynomial). Such results are also of interest in applications such as ECT (Emission Computed Tomography). LÄS MER
