1. Algorithms in data mining using matrix and tensor methods
Detta är en avhandling från Matematiska institutionenSammanfattning : In many fields of science, engineering, and economics large amounts of data are stored and there is a need to analyze these data in order to extract information for various purposes. Data mining is a general concept involving different tools for performing this kind of analysis. LÄS MER
2. Recognition and Evaluation by Video Synthesis Methods and Symmetry Features
Detta är en avhandling från Matematiska institutionenSammanfattning : Biometrics is being increasingly utilized for person authentication. It requires little or no efforts from the user as compared to traditional non-biometric systems where the user has to memorize PIN codes and passwords or carry pass cards and keys that can be easily forgotten or lost.

3. Simulations of thermoelectric transport in granularsuperconductors
Detta är en avhandling från Stockholm : KTHSammanfattning : This thesis presents results from numerical simulations of the Nernst effect dueto phase fluctuations in models of two-dimensional granular superconductors. Inaddition other transport properties, such as thermal conductivity and electrical re-sistivity are calculated. LÄS MER
4. Propagation of some coherent and partially coherent laser beams
Detta är en avhandling från Stockholm : KTHSammanfattning : In this thesis, we investigate the propagation of some coherent and partially coherent laser beams, including a dark hollow beam (DHB), an elliptical Gaussian beam (EGB), a flat-topped beam and a twisted anisotropic Gaussian Schell-model (TAGSM) beam, through a paraxial optical system or a turbulent atmosphere. Several theoretical models are proposed to describe a DHB of circular or non-circular symmetry. LÄS MER
5. Simple Modules over Lie Algebras
Detta är en avhandling från Uppsala : Department of MathematicsSammanfattning : Simple modules are the elemental components in representation theory for Lie algebras, and numerous mathematicians have worked on their construction and classification over the last century. This thesis consists of an introduction together with four research articles on the subject of simple Lie algebra modules. LÄS MER
