6. Ultraluminous sources in X-ray sky surveys
Master-uppsats, Uppsala universitet/HögenergifysikSammanfattning : Ultraluminous X-ray sources (ULXs) are extragalactic, non-nuclear, point-like X-ray sources whose luminosity supersedes that of the Eddington limit of an accreting stellar mass black hole (L> 10 ^ 39 erg / s). Most of them are powered by black holes and neutron stars undergoing genuine super-Eddington accretion, with a small handful of candidates being consistent with sub-Eddington accretion on an intermediate mass black hole.

7. Efficient Discovery Of Binary Stars
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationSammanfattning : Purpose: even in the era of exponential increase in the amount of stellar data gathered, binaries are still often overlooked in observational data due to the special handling they require. The goal of this work is to develop a method capable of automatically and efficiently identifying and extract double-lined spectroscopic binaries (SB2) from a spectroscopic survey, while being scalable and technically successful, and to identify and optimize the parameters that influence their detection.

8. Derivation of Improved K^0_L Response Uncertainty for use in the Jet Energy Scale Calibration at ATLAS
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikSammanfattning : The Standard Model of particle physics (SM) attempts to describe the fundamental particles and how they interact with each other. This model is however incomplete, as shown by various experimental observations. ATLAS is one of the experiments currently in operation at the Large Hadron Collider, which aims to search for new physics beyond the SM. LÄS MER
9. Konstruktionsåtgärd för lutande bränsletank
Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknikSammanfattning : Bränsle är en viktig substans för fordon och utan bränsle så är de flesta fordon inte funktionella. I de allra flesta instruktionsböcker för fordon så rekommenderas det att bränslet inte får nå en kritisk låg nivå av bränsle. Då man talar om den kritiska bränslenivån så handlar det om ¼ kvarliggande bränsle. LÄS MER
10. CO and CO2 Detection for Catalysis Diagnosis by Means of PLIF
Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. LÄS MER
