1. On some Nonlinear Aspects of Wave Motion
Abstract : In the first part of this thesis we consider the governing equations for capillary water waves given by the Euler equations with a free surface under the influence of surface tension over a flat bottom. We look for two-dimensional steady periodic waves. The problem is first transformed to a nonlinear elliptic equation in a rectangle. READ MORE

2. Helium measuring system for on-line fuel and control rod integrity surveillance in BWRs
Abstract : Accurate supervision of fuel and control rod integrity in a nuclear reactor core is very important for maintaining a safe and reliable operation of the reactor. Fuel rod failures can cause increased doses to personnel in the power plant, increased backend costs, limitations of the reactor operation and unplanned shut downs, which can lead to large economic losses.

3. Convection-diffusion equation in unbounded cylinder and related homogenization problems
Abstract : The thesis consists of two closely related papers (A and B). Paper A is concerned with the study of the behaviour at infinity of solutions to second order elliptic equation with first order terms stated in a half-cylinder. READ MORE

4. Power Reactor Noise Studies and Applications
Abstract : The present thesis deals with the neutron noise arising in power reactor systems. Generally, it can be divided into two major parts: first, neutron noise diagnostics, or more specifically, novel methods and algorithms to monitor nuclear industrial reactors; and second, contributions to neutron noise theory as applied to power reactor systems.

5. Studies on Diffusion of Surfactants and Macromolecules
Abstract : A new apparatus for measuring the translational diffusion coefficient in liquids at steady state is presented. The advantages of the described technique are i. the ability to characterize the dependence of the diffusion coefficient on concentration with a single experiment, and ii. READ MORE
