1. SECOND-ORDER DIVERGENCE-FREE FEM FOR MAGNETOHYDRODYNAMICS USING LAGRANGE POLYNOMIALS
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : AbstractMaxwell’s laws state that the divergence of a magnetic field always remains zero. In thecontinuous setting this is true for the magnetohydrodynamics equations. However, in thediscrete setting, the solution does not always remain divergence-free. READ MORE

2. Multibody simulations of vibrations in a truck’s steering system
University essay from KTH/Matematik (Avd.)Abstract : This thesis aims to explore if multibody simulations is a suitable method to investigate vibrations in the steering system of trucks. Vibrations in the steering system and subsequently in the steering wheel is a common issue that automotive manufacturers face. READ MORE

3. Calculating scattering amplitudes in φ3 and Yang-mills theory using perturbiner methods
University essay from Uppsala universitet/Teoretisk fysikAbstract : We calculate tree-level scattering amplitudes in φ^3 theory and Yang-Mills theory by means of the perturbiner expansion. This involves solving the Euler-Lagrange equations of motion perturbatively via a multi-particle ansatz, and using Berends-Giele recursion relations to extract the solution from simple on-shell data.

4. Jet fragmentation in shaped charges
University essay from KTH/Matematik (Avd.)Abstract : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. READ MORE

5. Towards a method for antenna impedance tailoring through shapeoptimization, with a bound on the associated cost-function
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Over the last years, there has been an interest in designing antennas that operateat higher frequencies. In most applications, these antennas work jointly withPower Amplifiers. However, most commercial Power Amplifiers have a nonstandardoptimal load-pull impedance in their optimal operating frequencies.
