1. Transitional and turbulent flow in porous media
Abstract : Fluid flow through porous media takes place in many natural processes such as ground water flows, capillary flows in plants and flow in human organs and muscles. It is also of outmost importance to have knowledge of this flow in a number of industrial processes such as paper making, making of fibre boards, composites manufacturing, filtering, forming and sintering of iron ore pellets and drying and impregnation of wood.

3. Cognitive behavioral therapy for children and adolescents with dental phobia
Abstract : Background: Dental phobia is a disabling and clinically significant fear that interferes with the dental care necessary for a child’s or adolescent’s well-being. In fact, the definition of oral health in children and adolescents stresses, not only sound and well-functioning dental and oral structures, but also an absence of dental fear and anxiety. READ MORE

4. Analysis and control of transitional shear flows using global modes
Abstract : In this thesis direct numerical simulations are used to investigate two phenomenain shear flows: laminar-turbulent transition over a flat plate and periodicvortex shedding induced by a jet in cross flow. The emphasis is on understanding and controlling the flow dynamics using tools from dynamical systems and control theory. READ MORE

5. Stability analysis and control design of spatially developing flows
Abstract : Methods in hydrodynamic stability, systems and control theory are applied to spatially developing flows, where the flow is not required to vary slowly in the streamwise direction. A substantial part of the thesis presents a theoretical framework for the stability analysis, input-output behavior, model reduction and control design for fluid dynamical systems using examples on the linear complex Ginzburg-Landau equation.
