1. Ternary quadratic forms over algebraic integers
Sammanfattning : .... LÄS MER
2. Quaternion Orders and Ternary Quadratic Forms Orders of Class Number One and Representations of Algebraic Integers by Quadratic Forms
Sammanfattning : Let R be the ring of integers in a totally real quadratic field K. The purpose of the thesis is to study totally definite quaternion R-orders and representations of elements in R by totally positive definite integral ternary quadratic forms. The thesis consists of three papers. LÄS MER
3. Some problems in the theory of quadratic forms
Sammanfattning : .... LÄS MER
4. On Parameter Estimation and Control of Time-Varying Stochastic Systems
Sammanfattning : This thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor.

5. Tools for Control System Design : Stratification of Matrix Pairs and Periodic Riccati Differential Equation Solvers
Sammanfattning : Modern control theory is today an interdisciplinary area of research. Just as much as this can be problematic, it also provides a rich research environment where practice and theory meet. This Thesis is conducted in the borderline between computing science (numerical analysis) and applied control theory. LÄS MER
