11. Rut Depth Prediction on Flexible Pavements - Calibration and Validation of Incremental-Recursive Models
Sammanfattning : In later years the development of pavement design has gone towards more and more analytically based methods. Future design will probably be based on incremental deterioration models. The objective is to evaluate different types of rut depth prediction models for an incremental design process. LÄS MER
12. Offshore deployments of marine energy converters
Sammanfattning : The depletion warning of non-renewable resources, such as gas, coal and oil, and the imminent effects of climate change turned the attention to clean and fossil fuel-free generated electricity. University research groups worldwide are studying solar, wind, geothermal, biomass and ocean energy harvesting. LÄS MER
13. 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.

14. Wave Loads and Peak Forces on Moored Wave Energy Devices in Tsunamis and Extreme Waves
Sammanfattning : Surface gravity waves carry enormous amounts of energy over our oceans, and if their energy could be harvested to generate electricity, it could make a significant contribution to the worlds power demand. But the survivability of wave energy devices in harsh operating conditions has proven challenging, and for wave energy to be a possibility, peak forces during storms and extreme waves must be studied and the devices behaviour understood.

15. Automated Production Technologies and Measurement Systems for Ferrite Magnetized Linear Generators
Sammanfattning : The interest in breaking the historical dependence on fossil energy and begin moving towards more renewable energy sources is rising worldwide. This is largely due to uncertainties in the future supply of fossil fuels and the rising concerns about humanity’s role in the currently ongoing climate changes. LÄS MER
