1. Internal Design of a Class of Self-Excited Synchronous Generators
Abstract : INTERNAL DESIGN OF A CLASS OF SELF-EXCITEDABSTRACTWith the increasing trend of distributed generation and the need for alternative and renewable energy sources, self-excited induction and synchronous reluctance generators have attracted more attention for wind, tidal and hydropower applications. This thesis is concerned with the development of a class of self-excited synchronous reluctance generators (SRG). READ MORE

2. Nonlinear Dust Particle Dynamics and Collective Effects in Complex Plasmas
Abstract : Theoretical studies of dusty plasmas have been performed by focusing attention principally on collective phenomena and on grain motion. This thesis consists of a collection of seven published papers that explore both the collective behavior of a complex plasma system as well as the dynamics of grains in plasmas. READ MORE

3. Drum Brake Squeal
Abstract : Drum brake squeal is a common discomfort. The main goal of this thesis is to investigate the mechanisms that generate drum brake squeal and to create a base for the search for solutions. A series of steps towards the understanding of these mechanisms are taken. Firstly, a simple model for friction-induced vibration is presented. READ MORE

5. From Macroscopic to Microscopic Dynamics of Superconducting Cavities
Abstract : Superconducting (SC) radio frequency (RF) cavities are at the heart of many large-scale particle accelerators such as the European Spallation Source (ESS), the X-ray Free Electron Laser (XFEL), the Linac Coherent Light Source (LCLS)-II and the proposed International Linear Collider (ILC). The SC cavities are essentially resonant structures with very high intrinsic quality factors (Q0) of the order of 1010. READ MORE
