Simulations of a Therapeutic Proton Beam with FLUKA Monte Carlo Code and Varian Eclipse Proton Planning Software
(The University of Bergen, 2013-11-20)
The sharp dose deposition from protons in a medium has some clear advantageous aspects for use in cancer treatment. When charged particles, for instance protons, traverse matter, most of their energy are deposited at the ...
Low Salinity Waterflood in Combination with Surfactant/Polymer; Effect of Surfactant Slug Size
(The University of Bergen, 2014-06-02)
In last years, there has been a growing interest in the effect of reducing salinity of injected water in oil recovery. Many studies have showed that low salinity waterflooding is a promising method that can lead to a ...
High Back Pressure on Pressure Safety Valves (PSVs) in a Flare System. Developing the Simulation model, Identifying and analyzing the back-pressure build-up
(The University of Bergen, 2013-10-01)
Process safety is a disciplined framework for managing the integrity of operating systems and processes handling hazardous substances. It is achieved by applying good design principles, engineering, and operating and ...
Finite element modeling of ultrasound measurement systems for gas. Comparison with experiments in air.
(The University of Bergen, 2013-06-10)
A finite element based system model of an ultrasonic measurement system in air is developed. Simulations and experiments in air are compared.
Måling av akustisk spreiing fra makrellbein
(The University of Bergen, 2006-06)
Correlated ionization processes in atoms and molecules
(The University of Bergen, 2013-09-27)
This thesis is composed of five scientific papers written between 2009 and 2013. The focus of this work is on various photo-ionization processes in small atoms and molecules. The strong field phenomenon called “atomic ...
Fundamental aspects of water methane separation in zeolites
(The University of Bergen, 2013-06-03)
The main objective of this thesis was to use molecular dynamics to investigate the methane interactions with zeolite, specifically the Linde Type A-3A, alongside with an investigation into the use of polynomial path ...
Challenges related to storage and transfer of solar energy with a case study on long distance power transfer
(The University of Bergen, 2010-06-21)
The challenges that will be discussed in this thesis are two-fold; the problems related to trans- mission of power over long distances, and the need for energy storage, especially at night. Both of the issues are accentuated ...
Hydrate Formation and CH4 Production from Natural Gas Hydrates - Emphasis on Boundary Conditions and Production Methods
(The University of Bergen, 2009-05-13)
Natural gas hydrate is a solid state of gas and water at low temperature and high pressure. Gas hydrates are known to form hydrate plugs in production line, and has thus generally been considered a problem to the oil ...
Two Higgs Doublets plus One Dark Matter Singlet
(The University of Bergen, 2010-08-01)
In this thesis an extension of the 2HDM (see chapter 1) is explored. The extension admits an extra inert singlet which is a dark matter candidate. Before the exploration a large part of the thesis (chapter 2) is an ...
