2. Numerical Modelling and Statistical Analysis of Ocean Wave Energy Converters and Wave Climates
Abstract : Ocean wave energy is considered to be one of the important potential renewable energy resources for sustainable development. Various wave energy converter technologies have been proposed to harvest the energy from ocean waves. This thesis is based on the linear generator wave energy converter developed at Uppsala University. READ MORE

4. Wave Propagation in Structural Elements - Direct and Inverse Problems in the Time Domain
Abstract : The subject of this thesis is direct and inverse wave propagation problems in structural elements. The considered structures are beams, plates and rods. The models for the beams and the plates are based on linear theory, while the rods are assumed to be nonlinear. The greater part of the work concerns the Timoshenko beam. READ MORE

5. Wave Energy Converters : An experimental approach to onshore testing, deployments and offshore monitoring
Abstract : The wave energy converter (WEC) concept developed at Uppsala University consists of a point absorbing buoy, directly connected to a permanent magnet linear generator. Since 2006, over a dozen full scale WECs have been deployed at the Lysekil Research Site, on the west coast of Sweden. READ MORE
