21. Nonlinear dynamics of strongly-bound magnetic vortex pairs
Sammanfattning : This work is a study of nonlinear phenomena in vertically stacked pairs of magnetic vortices. New dynamic regimes are uncovered with a decrease in the inter-vortex separation to below the lateral vortex-core size. LÄS MER
22. Numerical predictions of heat-transfer applied to electrical machines
Sammanfattning : In order to meet the need for increased electrification, and at the same time reduce the total demand for electric energy, behavior change and technological innovation is needed. Over the decades power density of electric motors have increased, leading to increased demands on the cooling system design and performance. LÄS MER
23. Robust and Durable Vacuum Insulation Technology for Buildings
Sammanfattning : Today’s buildings are responsible for 40% of the world’s energy use and also a substantial share of the Global Warming Potential (GWP). In Sweden, about 21% of the energy use can be related to the heat losses through the climatic envelope. LÄS MER
24. Stellar kinematics in surveys and simulations
Sammanfattning : We study stellar motions in the Milky Way with N-body simulations and large astrometric samples from ESA's Gaia mission. We identify two kinematic populations for white dwarfs in the Solar neighbourhood. We also investigate the accreted halo and reveal two new structures. LÄS MER
25. Finite Element simulations: computations and applications to aerodynamics and biomedicine
Sammanfattning : Partial Differential Equations describe a large number of phenomena of practical interest and their solution usually requires running huge simulations on supercomputing clusters. Especially when dealing with turbulent flows, the cost of such simulations, if approached naively, makes them unfeasible, requiring modelling intervention. LÄS MER
