1. Fluid Mechanics of Vertical Axis Turbines : Simulations and Model Development
Abstract : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. READ MORE

2. Long-Term Simulation of Coastal Evolution
Abstract : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. READ MORE

3. Multiple Antenna Terminals in Realistic Environments - A Composite Channel Modeling Approach
Abstract : For evaluation of specific antenna arrangements in wireless communication systems we need physical channel models that take into account also the directional domain of the propagation channel. In this thesis we investigate, validate and propose a practical approach to wireless channel modeling and, particularly, to mobile communication systems. READ MORE

4. Prediction of Mobile Radio Channels : Modeling and Design
Abstract : Prediction of the rapidly fading envelope of a mobile radio channel enables a number of capacity improving techniques like fast resource allocation and fast link adaptation. This thesis deals with linear prediction of the complex impulse response of a channel and unbiased quadratic prediction of the power. READ MORE

5. Model Selection and Sparse Modeling
Abstract : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. READ MORE
