6. Performance Evaluation and Life Cycle Cost Analysis of the Electrical Generation Unit of a Wave Energy Converter
Abstract : The main focus of this work is the performance and the economical assessment of a radial flux generator that is used in wave power applications. The wave energy converter (WEC) used in this work is a point absorber, that is considered to move only in heave. READ MORE

7. Geometry Optimization of an Interior Permanent Magnet Machine for Electric Vehicles - Life Cycle Cost Minimization for City, Rural and Highway Driving
Abstract : This thesis investigates the benefits of customizing an Interior Permanent magnet Machine (IPM) for a specific combination of city, rural and highway driving. Focus lies on the potential to reduce the Life Cycle Cost (LCC) of the IPM and power electronic converter, for an example Battery Electric Vehicle (BEV), by custom-making the IPM. READ MORE

8. Medium Voltage Generation System with Five-level NPC Converters for Kite Tidal Power
Abstract : Offshore power generation has emerged as a prominent source of energy and the installed capacity of new plants has been steadily increasing in recent years. Tidal power specifically is a promising renewable energy source which has not been highly exploited yet, despite its distinctive advantages of being predictable and independent of weather conditions.

9. Modelling and Experimental Verification of Direct Drive Wave Energy Conversion : Buoy-Generator Dynamics
Abstract : This thesis is focused on development of models and modelling of a wave energy converter in operation. Through the thesis linear potential wave theory has been used to describe the wave-buoy interaction. The differences lie in the generator models, in the simplest model the generator is a mechanical damper characterized by a damping factor. READ MORE

10. Flow Maldistribution in Exhaust Aftertreatment Systems - Numerical Simulations
Abstract : To comply with the stringent emission norms under every driving condition, including the coldstart conditions and Real Driving Emissions (RDE) tests, accurate models that capture the spatial and temporal variation of flow distribution information in Exhaust AfterTreatment Systems (EATS) are required. This study is aimed at characterizing and quantifying flow distribution in EATS under transient conditions with realistic geometry that illustrates the complex nature of the flow conditions. READ MORE
