1. Linear and non-linear dynamics of non-autonomous flows
Abstract : Fluid flows subject to time-dependent external forces or boundary conditions are ubiquitous in biology and technical applications. Whether one considers birds flying by flapping their wings or the gust response of wind turbines, the flow is non-autonomous. READ MORE

2. Lattice dynamics : From fundamental research to practical applications
Abstract : The reason to perform calculations in material science usually falls into one of two categories: to predict or explain the origin of material properties. This thesis covers first-principle calculations for solids at extreme conditions, from both of the two mentioned categories. READ MORE

3. Theoretical perspectives on ultrafast and non-linear spectroscopy
Abstract : In this thesis we discuss a theoretical description of ultrafast and non-linear spectroscopy. Due to the high intensities and ultrashort pulse durations involved in such experiments, it is necessary to use an explicitly time-dependent formalism. READ MORE

4. Population and Community Dynamics in Variable Environments
Abstract : All natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. READ MORE

5. 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
