1. 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
2. The quest for a classical bulge - a study of kinematics, abundances, and ages using microlensed dwarf stars and Gaia
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter.

3. Automatiserade sorteringsprocesser för textilavfall : En studie av återvinningseffektivitet och resursflöden
Kandidat-uppsats, KTH/ProduktionsutvecklingSammanfattning : Textilkonsumtion i världen har ökat drastiskt under de senaste decennierna, vilket också syns i övergången till att fast fashion nu dominerar textilindustrin. Även i Sverige har konsumtionen ökat, vilket bidrar till att textilindustrin skapar allvarliga följder för miljön. LÄS MER
4. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. LÄS MER
5. Solutions for presence detection in an intercom door station
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : In this work, different solutions for human presence detection in a door intercom device are examined. The study was conducted at a company in Lund, Sweden. LÄS MER
