1. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator
Abstract : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. READ MORE

2. Modelling and Experimental Verification of Direct Drive Wave Energy Conversion : Buoy-Generator Dynamics
Abstract : This thesis is focused on development of models and modelling of a wave energy converter in operation. Through the thesis linear potential wave theory has been used to describe the wave-buoy interaction. The differences lie in the generator models, in the simplest model the generator is a mechanical damper characterized by a damping factor. READ MORE

3. Microwave and millimeter wave CMOS Characterization, modeling, and design
Abstract : The use of CMOS technologies for microwave and millimeter wave applications has recently been made possible as a result of increased transistor performance. The fT and fmax have, for example, passed 100 GHz at the 130 nm node and 200 GHz at the 65 nm node. READ MORE

4. Fully Nonlinear Unsteady Three-Dimensional Boundary Element Method for Ship Motions in Waves
Abstract : The prediction of the behavior of ships in a seaway has been an important topic in ship design since the beginning of modern naval architecture. In recent years, computer simulations using numerical methods based on mathematical models of the ship hydrodynamics problem has become a valuable tool for researchers and engineers working in this field.

5. Numerical Investigation of Ship Responses in Calm Water and Regular Head Waves
Abstract : In order to design fuel efficient ships and install right machinery onboard, ship designers need to know the interaction effects between hull, propeller and appendages in realistic operating conditions. Neglecting the interaction effects may result in under/over-prediction of the required power. READ MORE
