1. Nonlinear dynamics in transitional wall-bounded flows
Abstract : This thesis focuses on numerical studies of subcritical transition to turbulence in shear flows. The thesis employs a framework based on nonlinear dynamics in the subsequent studies. The geometrical approach to subcritical transition pivots the concepts of edge manifold and edge state. READ MORE

2. Transitional and turbulent fibre suspension flows
Abstract : In this thesis the orientation of macro-sized fibres in turbulent flows is studied, as well as the effect of nano-sized fibrils on hydrodynamic stability. The focus lies on enabling processes for new materials where cellulose is the main constituent. READ MORE

3. Modelling and control of turbulent and transitional flows
Abstract : The dynamics of fluid motion can accurately be described by the Navier– Stokes equations. Manipulating these equations to reduce their complexity but preserving their main characteristics has always been a key research activity in the field of fluid mechanics. READ MORE

4. Towards an understanding of dynamics in information visualization
Abstract : This work is about interaction. Research in the field of information visualization has traditionally been slanted more towards presentation; this even though humans are interactive creatures. We observe our surroundings, make decisions based on what we see and react back into the world. READ MORE

5. Chronic disease risk factors in a transitional country : the case of rural Indonesia
Abstract : Background: The epidemic of chronic diseases is largely neglected. Although a threatening burden of chronic diseases is emerging, developing public health efforts for their prevention and control is not yet a priority for trans-national and national health policy makers. READ MORE
