Chemical composition of giant planet hosts

De stjärnor man kan se på himmeln en riktigt stjärnklar natt - omkring 3000 - är bara en bråkdel av alla de som faktiskt finns i universum. Ljuset har en hög men inte oändlig hastighet. Därför kan vi bara se sådant som ligger tillräckligt nära jorden, så att ljuset hunnit färdas hit under universums livstid. De himlakroppar som ligger längst bort ifrån jorden men som fortfarande går att se (med teDoes the formation of planets give imprints on the chemical composition of the host star? In order to test this theory a differential abundance analysis (i.e. comparing two stars' abundances to each other) was carried out on a few stars with and without known planets, to see if any differences were found. The analysis was based on high resolution, high signal to noise ratio (SNR) spectra of fo

The goal of this master's thesis was to develop an equine gait recognition algorithm. Triaxial accelerometer and gyroscope signals were collected during different riding sessions by usin

A study of the stellar populations in the Kepler field

Det är uppskattat att det finns fler stjärnor i universum än vad det finns sandkorn på jordens stränder och öknar tillsammans. Precis som stränder och öknar formar vår värld formar stjärnor vår galax och det bortom denna, och precis som att ett sandkorn är för lite för att berätta något viktigt om en strand, ger en stjärna inte mycket information till astronomer. Men många stjärnor i ett till varaStudying the formation and evolution of galaxies is a fundamental problem in astronomy that warrants repeated investigation by astronomers. How do spiral galaxies like our own come to have its distinct spiral arms? How do stars and their properties change over time and will they continue to evolve in the same manner? To try and attempt to answer such questions we need to look to our own Galaxy the

EGS : Framtidens Geotermiska System

En ökad efterfrågan på miljövänliga energialternativ har resulterat i att allt fler länder börjat utvärdera sina geotermala tillgångar. En bidragande orsak till det ökade geotermala intresset är förändrade krav som ställs på geologin och hydrologin med dagens moderna EGS-anläggningar. Med EGS-tekniken (Enhanced Geothermal Systems) skapar man idag konstgjorda reservoarer, för fjärrvärme- och elprodThe increasing demand for eco-friendly energy alternatives and the changing requirements of state of the art EGS-plants (Enhanced Geothermal Systems) have set the mark for many countries to start evaluating their geothermal assets. By using the EGS-technique, artificial reservoir providing district heating and electricity are created around the world by stimulating the bedrock hydrostatically with

The mass balance and equilibrium line altitude trends of glaciers in northern Sweden

Glaciers are of extreme importance since they hold climatic data going back 2,000 years. Glaciers can provide important services such as ecosystem services, habitats, water runoff, and hydro-energy. They also affect the Earth’s processes and many feedback mechanisms. Glaciers all over the world are under the threat of climate change which may eventually lead to the disappearance of many of these i

Reducing lead time during installation projects through Continuous Improvement and Early Management

Problem: Tetra Paks strategi är att expandera World Class Manufacturing(WCM) från produktionen till att täcka installationsprojekt för att reducera dess ledtid. Det finns dock en stor utmaning för att utföra detta, då flera avdelningar är inblandade samt osäkerheterna kring att installationerna utförs ute hos kund. Frågan är därför; hur kan Tetra Pak använda Early Management metodologi från WCM föProblem: Tetra Pak’s strategy is to expand World Class Manufacturing (WCM) from manufacturing to installation projects in order to reduce the installation lead time. There is a challenge in the WCM implementation since it requires a cross-functional approach and uncertainties with the installation projects being at customer’s site. The question at hand is; how can Tetra Pak use the Early Managemen

Reforestation of Alpine Grasslands in South Tyrol : assessing spatial changes based on Landsat data 1986-2016

The Alps are undergoing constant landscape changes due to modern socio economic changes. Especially grassland ecosystems of alpine meadows and pastures are threatened by the slow abandonment of the alpine transhumance traditions. This influences not only biodiversity but also the important cultural landscape seen as a valuable heritage in the Alps. The landscape in the North Italian alpine provinc

U-Pb datering av zirkon från migmatitisk gnejs i Delsjöområdet, Idefjordenterrängen

Under den Svekonorvegiska orogenesen omkristalliserade stora delar av sydvästra Sverige och bildade metamorfa migmatitiska gnejser. I Idefjordenterrängen, väster om Mylonitzonen, har migmatiterna inte daterats och då kunskapen om de metamorfa processerna i området brister kan migmatiterna ge en bättre bild av när metamorfosen skedde. En migmatitisk gnejs från Delsjöområdet i östra Göteborg har datDuring the Sveconorwegian orogenesis, parts of southwestern Sweden was recrystallized and formed metamorphic migmatites. In the Idefjorden terrane, west of the Mylonite zone, the migmatites have not been dated and since knowledge of the metamorphic processes in the area is lacking, the migmatites can provide better constraints of when metamorphosis occurred. A migmatitic gneiss from the Delsjö are
