Hardness and Microstructure for Ge-Containing Al-Mg-Si-Cu alloys
(Master thesis, 2012)Four different Al-Mg-Si-Cu-Ge alloys with 0.002--0.037 at.\% germanium were heat treated to the T6 condition and over-aged at 250$^{\circ}$C for up to 100 hours. The hardness was tested during the over-ageing and there ... -
Head-On Beam-Beam Interactions in High-Energy Hadron Colliders - GPU-Powered Modelling of Nonlinear Effects
(Master thesis, 2017)The performance of high-energy circular hadron colliders, as the Large Hadron Collider, is limited by beam-beam interactions. The strength of the beam-beam interactions will be higher after the upgrade to the High-Luminosity ... -
High-Resolution Large Time-Step Schemes for Hyperbolic Conservation Laws
(Master thesis, 2015)This thesis is concerned with numerical methods for solving hyperbolic conservation laws. A generalization of large time-step schemes (LTSS) to high resolution is presented. The generalization is based on the previous work ... -
Hyperspectral Imaging of In Vitro Wound Models from Human Skin
(Master thesis, 2014)In vitro wounds from human skin have been analysed using hyperspectral imaging. The purpose of this research is to use hyperspectral imaging as a diagnosis tool for skin wounds. The imaging period was 22 days. The images ... -
Identifying Lagrangian Coherent Structures Using Clustering
(Master thesis, 2018)In these times of rapid environmental changes, our understanding of nature becomes ever more crucial. For example, the spread of oil spills and microplastics can have far reaching consequences for the ecology. Previous ... -
In-plane Fracture Front Propagation in the Thin Plate Fiber Bundle Model
(Master thesis, 2016)A new history independent thin plate Fiber Bundle Model is derived in or- der to model in-plane material fracture. The model provides an easy way of studying the not yet fully understood fracture processing zone. Only ... -
In-situ µ-CT of well cement exposed to CO2-saturated water at high pressure and temperature
(Master thesis, 2018)Large-scale implementation of carbon dioxide (CO2) sequestration in depleted oil and gas reservoirs may potentially mitigate global climate change. However, successful CO2 storage is contingent on a limited leakage through ... -
Investigating the excitation spectrum of a spin-orbit coupled Bose-Einstein condensate
(Master thesis, 2017)The excitation spectrum of a spin-orbit coupled Bose-Einstein condensate is investigated by the use of the Bose-Hubbard model and a mean-field approach. The undiagonalized Hamiltonian matrix for a general inversion-symmetric ... -
Investigation of Co2AlO4/CeO2 Catalyst for N2O Abatement using Electron Microscopy Techniques
(Master thesis, 2014)A N2O abatement catalyst of a Co2AlO4 active phase and CeO2 support phase has been investigated using transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM) and scanning electron microscopy ... -
Laser light deformation of microdroplets
(Master thesis, 2014)This masters work describes the deformation of a droplet that is illuminated by a laser beam. The theory for linear fluid mechanical motion of the droplet is discussed. This is combined with Lorenz-Mie scattering. Droplet ... -
Light Emission of Streamers in Dielectric Liquids
(Master thesis, 2017)Liquid insulation is widely used in various high voltage equipments crucial to a modern electrical grid. It is thus important to understand the behaviour and limits of performance for such liquids. In these experiments, ... -
