Condensation of water on rust surfaces, and possible implications for hydrate formation in pipelines
(Master thesis, 2011-06-01)The threat of climate change has put the spotlight on the increase in carbon emissions and possible methods to attenuate it. As a consequence of this, oil and gas companies have started to consider both how to reduce ... -
Construction and evaluation of a temperature dependent laminar burning velocity model for inerted hydrogen, methane and carbon monoxide mixtures
(Master thesis, 2017-06-22)The laminar burning velocity is an important mixture property providing information about different gas mixtures’ reactivity. It is extensively used in the computational fluid dynamics (CFD) program FLACS to calculate ... -
Construction of a plan library for high risk prostate cancer patients in proton therapy
(Master thesis, 2017-06-27)High-risk prostate cancer patients can receive treatment of both the pelvic lymph nodes and seminal vesicles, in addition to the prostate based on an estimated risk of lymph node spread. Due to the large volume being ... -
CP Violation in the Two Higgs Doublet Model
(Master thesis, 2010-06)We look into CP violating properties in the two Higgs Doublet Model and search for the possibility that Spontaneous and Explicit CP Violation have no physical difference. -
Current systems associated with Non-Conjugate Aurora
(Master thesis, 2015-01-20)The main goal of this Thesis is twofold. First, we want to develop a solid method for identifying the field aligned currents related to the specific non-conjugate auroral features identified by Reistad et al. [2013] and ... -
Dark Matter Searches with ATLAS and Fermi
(Master thesis, 2013-06-03)This thesis presents Dark matter inspired searches for supersymmetry with a one-tau analysis at ATLAS, which excludes a region close to that of allowed dark matter densities at m_0 ~ 400 GeV, m_1/2 ~ 600 GeV, tan \beta = ... -
