1. Tools for Control System Design : Stratification of Matrix Pairs and Periodic Riccati Differential Equation Solvers
Abstract : Modern control theory is today an interdisciplinary area of research. Just as much as this can be problematic, it also provides a rich research environment where practice and theory meet. This Thesis is conducted in the borderline between computing science (numerical analysis) and applied control theory. READ MORE

2. Non-linear inverse geothermal problems
Abstract : The inverse geothermal problem consist of estimating the temperature distribution below the earth’s surface using temperature and heat-flux measurements on the earth’s surface. The problem is important since temperature governs a variety of the geological processes including formation of magmas, minerals, fosil fuels and also deformation of rocks. READ MORE

3. The influence of numbers when students solve equations
Abstract : Is it possible that some students’ primary difficulty with equation-solving is neither handling the literal symbols nor the equality, but the numbers used as coefficients? It is well known that many students find algebra a difficult topic, and there is much research on how students experience this strand of mathematics, with indications of how it can be taught. Still, a perspective not often fronted in this research – that has been suggested as an area potentially important – is how numbers, other than natural numbers, in algebra, are perceived by students.

4. Numerical Vlasov–Maxwell Modelling of Space Plasma
Abstract : The Vlasov equation describes the evolution of the distribution function of particles in phase space (x,v), where the particles interact with long-range forces, but where shortrange "collisional" forces are neglected. A space plasma consists of low-mass electrically charged particles, and therefore the most important long-range forces acting in the plasma are the Lorentz forces created by electromagnetic fields.

5. Convergence analysis of domain decomposition methods : Nonlinear elliptic and linear parabolic equations
Abstract : Domain decomposition methods are widely used tools for solving partial differential equations in parallel. However, despite their long history, there is a lack of rigorous convergence theory for equations with non-symmetric differential operators. This includes both nonlinear elliptic equations and linear parabolic equations. READ MORE
