1. The visibility of stellar transients in the Galactic Centre
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. LÄS MER
2. N-body simulations of exoplanets and their moons
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. LÄS MER
3. Development of osmo- and appetite regulation during transfer of smolt from freshwater to increasing salinities
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Atlantic salmon (Salmo salar) is common in Scandinavian aquaculture and must be transferred from freshwater to seawater to grow properly. Despite being assessed as ready smolts, meaning they have gone through the physiological changes to prepare for SW transfer, the transfer result in a mortality rate of around 13-19%, and significant appetite- and growth reductions.

4. Study of oblique whistler waves in coronal mass ejections observed by Solar Orbiter
Kandidat-uppsats, Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : In this paper a search routine in MATLAB was developed in order to find and analyze oblique whistler waves in the data from the ESA and NASA spacecraft Solar Orbiter. Oblique whistler waves are a type of plasma wave which propagate at an angle with respect to the background magnetic field. LÄS MER
5. Development of a new SBRT dose planning strategy for thoracic tumours in RayStation
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/RadiofysikSammanfattning : Umeå University Hospital has acquired a new treatment planning system, RayStation, for radiotherapy. It has a different set of dose calculation algorithms that require new planning strategies for stereotactic lung cancer treatments. LÄS MER
