1. Adaptive Finite Element Methods for Optimal Control Problems
Sammanfattning : In this thesis we study the numerical solution of optimal control problems. The problems considered consist of a systemof differential equations, the state equations, which are governed bya control variable. The goal is to determine the states and controls which minimize a given cost functional. LÄS MER

3. Duality-based adaptive finite element methods with application to time-dependent problems
Sammanfattning : To simulate real world problems modeled by differential equations, it is often not sufficient to consider and tackle a single equation. Rather, complex phenomena are modeled by several partial dierential equations that are coupled to each other. LÄS MER
4. Higher Order Finite Elements and Adaptivity in Computational Electromagnetics
Sammanfattning : This thesis is concerned with efficient and accurate numerical methods for the solution of Maxwell's equations. In particular, the finite element method with higher order elements and adaptive mesh-refinement is considered. LÄS MER
5. Finite element methods for multiscale/multiphysics problems
Sammanfattning : In this thesis we focus on multiscale and multiphysics problems. We derive a posteriori error estimates for a one way coupled multiphysics problem, using the dual weighted residual method. LÄS MER
