11. Experimental results from the Lysekil Wave Power Research Site
Abstract : This thesis presents how experimental results, from wave power research performed offshore at the Lysekil research site, were obtained. The data were used to verify theoretical models as well as evaluate the feasibility of wave power as a future sustainable energy source. READ MORE

12. Numerical modelling and analysis of friction contact for turbine blades
Abstract : High cycle fatigue failure of turbine and compressor blades due to resonance in the operating frequency range is one of the main problems in the design of gas turbine engines. To suppress excessive vibrations in the blades and prevent high cycle fatigue, dry friction dampers are used by the engine manufacturers. READ MORE

13. Neural correlates of skilled movement : functional mapping of the human brain with fMRI and PET
Abstract : Humans have unique abilities to perform certain types of skilled voluntary movements. In this thesis we examine the neural substrates of. (i) fine digit actions, in particular the control of fingertip forces during manipulation, and (ii) the coordination of voluntary movements of different limbs. READ MORE

14. Rotor dynamical modelling and analysis of hydropower units
Abstract : In almost all production of electricity the rotating machines serves as an important part of the energy transformation system. In hydropower units, a hydraulic turbine connected to a generator converts the potential energy stored in the water reservoir into electrical energy in the generator. READ MORE
