16. Spatialanalys av markgeokemi : Hur utlakningshalter av markgeokemin varierar i Sveriges morän enligt interpolationsmetoder
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The purpose of this study was to evaluate the spatial distribution of geochemistry in Swedish till and whether interpolations could predict unknown values of geochemistry between samples at a national spatial level, Sweden, and a regional, the county of Västerbotten. The information of the spatial distribution of the elements and the interpolations accurateness has several applications. LÄS MER
17. Implementation and study of boundary integral operators related to PDE:s in the plane
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : The method of solving boundary value problems of partial differential equations numerically by first reformulating the problem as a boundary integral equation has many advantages over other methods, but also some unique difficulties. Some of these difficulties stem from problems in evaluating singular or nearly singular integral operators, and solving these difficulties is an active field of research. LÄS MER
18. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. LÄS MER
19. Trajectory Optimisation of a Spacecraft Swarm Maximising Gravitational Signal
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : Proper modelling of the gravitational fields of irregularly shaped asteroids and comets is an essential yet challenging part of any spacecraft visit and flyby to these bodies. Accurate density representations provide crucial information for proximity missions, which rely heavily on it to design safe and efficient trajectories. LÄS MER
20. 1000 Extra
Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljöSammanfattning : “1000 Extra” is a project that takes off in the sub optimal conditions that city planning in the 20-th century has left behind for the future. First and foremost looking at the conditions of residential areas planned based on doctrines stemming in modernism, the project proposes desnsifying the not-so-dense areas in Lund, consisting of row houses and other residential buildings in the same category of density.
