16. Hypergeometric functions in several complex variables
Abstract : This thesis deals with hypergeometric functions in several complex variables and systems of partial differential equations of hypergeometric type. One of the main objects of study in the thesis is the so-called Horn system of equations: xiPi(θ)y(x) = Qi(θ)y(x), i = 1, ... READ MORE

17. Algebraic Approaches to Normal Forms and Zero Dynamics
Abstract : The normal form of affine state space systems has been extensively studied during the last decade and it has found several important applications. Two such applications are exact input-output linearization and sliding mode control. A property of affine nonlinear systems that is simple to compute given a normal form is the zero dynamics.

18. Simplified dynamic analysis of railway bridges under high-speed trains
Abstract : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges. This is mainly due to the fact that a train at high speeds can cause resonance in the bridge superstructure. READ MORE

19. Theoretical Investigation into Longitudinal Dispersion in Natural Rivers — A Scaling Dispersion Model
Abstract : Using a broad variety of scientific methods this dissertation systematically investigates the fundamental mechanisms underlying the dispersion processes in natural rivers and their mathematical descriptions in a geometrical framework. Emphasis is on the geometrical variations and irregularities of a natural river and their scales. READ MORE

20. Numerical methods for inverse heat conduction problems
Abstract : In many industrial applications one wishes to determine the temperature history on the surface of a body, where the surface itself is inaccessible for measurements. The sideways heat equation is a model of this situation. READ MORE
