1. Ocean Wave Energy : Underwater Substation System for Wave Energy Converters
Sammanfattning : This thesis deals with a system for operation of directly driven offshore wave energy converters. The work that has been carried out includes laboratory testing of a permanent magnet linear generator, wave energy converter mechanical design and offshore testing, and finally design, implementation, and offshore testing of an underwater collector substation.

2. Numerical Modelling and Statistical Analysis of Ocean Wave Energy Converters and Wave Climates
Sammanfattning : 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. LÄS MER
3. Piezoelectric Generation and Damping of Extensional Waves in Bars
Sammanfattning : This thesis focuses on the electromechanical processes of generation and damping of transient waves in bars with attached piezoelectric members. In particular, the influence of amplifier and electrical circuitry on the mechanical waves is of interest. LÄS MER
4. Wave Propagation in Structural Elements - Direct and Inverse Problems in the Time Domain
Sammanfattning : 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. LÄS MER
5. Wave Energy Converters : An experimental approach to onshore testing, deployments and offshore monitoring
Sammanfattning : 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. LÄS MER
