1. On adaptive finite element methods based on a posteriori estimates

2. Mathematical analysis and approximation of a multiscale elliptic-parabolic system
Sammanfattning : We study a two-scale coupled system consisting of a macroscopic elliptic equation and a microscopic parabolic equation. This system models the interplay between a gas and liquid close to equilibrium within a porous medium with distributed microstructures. We use formal homogenization arguments to derive the target system. LÄS MER
3. On A Posteriori Error Estimation in the Maximum Norm
Sammanfattning : In this thesis we consider residual-based a posteriori error estimates in the maximum norm for the finite element solution of some partial differential equations. The thesis consists of three papers. The first paper concerns a pointwise a posteriori error estimate for the time dependent obstacle problem. LÄS MER
4. A priori and a posteriori error estimates and adaptive finite element methods for a model eigenvalue problem
Sammanfattning : .... LÄS MER
5. A moving boundary problem for capturing the penetration of diffusant concentration into rubbers : Modeling, simulation and analysis
Sammanfattning : We propose a moving-boundary scenario to model the penetration of diffusants into rubbers. Immobilizing the moving boundary by using the well-known Landau transformation transforms the original governing equations into new equations posed in a fixed domain. LÄS MER
