11. Buoy and Generator Interaction with Ocean Waves : Studies of a Wave Energy Conversion System
Abstract : On March 13th, 2006, the Division of Electricity at Uppsala University deployed its first wave energy converter, L1, in the ocean southwest of Lysekil. L1 consisted of a buoy at the surface, connected through a line to a linear generator on the seabed. READ MORE

12. Railway wheel steel behaviour upon thermo-mechanical loadings
Abstract : Optimised railway maintenance techniques such as rail grinding and milling, or rail repair welding, are vital to more sustainable rail networks. As demands on the railway increases, the need to better understand the material behaviour during local heating events occurring during maintenance is amplified. READ MORE

13. The Bone Conduction Implant (BCI) - Preclinical Studies, Technical Design and a Clinical Evaluation
Abstract : The Bone Conduction Implant (BCI) system has been developed as an alternative to the percutaneous bone anchored hearing aid (BAHA) with the advantage that the skin is kept intact. The transducer is permanently implanted and attached to the skull via a flat surface contact to the temporal bone. READ MORE

14. Thermal impact on rolling contact fatigue of railway wheels
Abstract : Rolling contact fatigue (RCF) is a very common and costly damage mechanism for rails and wheels. This thesis investigates the influence of combined thermal and mechanical loading on RCF of railway wheels on the basis of numerical predictions. READ MORE

15. Characterization of nano-scale materials for interconnect and thermal dissipation application in electronics packaging
Abstract : This thesis focuses on studies of nano-scale materials in electronic packaging applications with respect to following aspects: surface analysis of nano-scale oxide of lead-free solder particles, and thermal performance and mechanical property studies of nano-scale fiber and metal composite-based thermal interface materials. The composition and thickness of the solder oxide have a direct impact on the quality of interconnects and the reliability of a packaged system. READ MORE
