1. Airway pressure release ventilation : A systematic experimental approach
Abstract : Airway pressure release ventilation (APRV) is a ventilatory mode which allows unrestrictedspontaneous breathing (SB) throughout the ventilatory cycle. If SB is insufficient, mechanicalventilatory support is achieved by brief periodic decreases of the airway pressure below the CPAPlevel. READ MORE

2. Adaptive time-integration for goal-oriented and coupled problems
Abstract : We consider efficient methods for the partitioned time-integration of multiphysics problems, which commonly exhibit a multiscale behavior, requiring independent time-grids. Examples are fluid structure interaction in e.g., the simulation of blood-flow or cooling of rocket engines, or ocean-atmosphere-vegetation interaction. READ MORE

3. Asymptotic analysis of a nonlinear partial differential equation in a semicylinder
Abstract : We study small solutions of a nonlinear partial differential equation in a semi-infinite cylinder. The asymptotic behaviour of these solutions at infinity isdetermined. First, the equation under the Neumann boundary condition is studied. READ MORE

4. Asymptotic analysis of solutions to elliptic and parabolic problems
Abstract : In the thesis we consider two types of problems. In Paper 1, we studysmall solutions to a time-independent nonlinear elliptic partial differential equation of Emden-Fowler type in a semi-infnite cylinder. The asymptotic behaviour of these solutions at infnity is determined. First, the equation under the Neumann boundary condition is studied. READ MORE
