Challenges related to storage and transfer of solar energy with a case study on long distance power transfer
(Master thesis, 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 ... -
Characterization of a neutral helium beam for helium microscopy
(Master thesis, 2015-06-29)Neutral helium beam microscopy is a new development in scientific instrumentation where neutral helium atoms are utilized to image a sample. The main advantage of using neutral helium is the significantly smaller energy ... -
Characterization of Associating Polymer (AP) Solutions. Influences on flow behavior by the degree of hydrophobicity and salinity
(Master thesis, 2013-06-02)The most applied polymer today for chemical improved oil recovery (IOR) processes, such as polymer flood and/or polymer well treatments, is the synthetic partially hydrolyzed polyacrylamide (HPAM) and its derivatives. ... -
Characterization of Hyper Spectral Irradiance and Radiance Sensors
(Master thesis, 2013-09-11)It is surprisingly problematic to to accurately measure light in the laboratory. Even more so when measuring in the field. There are lots of areas where measuring light spectrum and irradiance outside a laboratory is of ... -
Characterization of the ALPIDE chip with Helium-4 ions for Proton Computed Tomography
(Master thesis, 2018-12-06)Particle therapy has become an appealing therapeutic option for patients with various tumor types. The physical properties of charged particles allow for an improved dose distribution conformality compared to conventional ... -
Characterization of the ALPIDE Detector with Proton Beams for the Development of a Prototype Computed Tomography Machine at the University of Bergen
(Master thesis, 2018-07-04)In conventional radio therapy, photons is used in the treatment. Treatment with protons, however, greatly reduce the energy which is deposited in healthy tissue surrounding the tumor. The aim for the pCT group at the ... -
Characterization studies of a GEM detector prototype for the ALICE TPC upgrade for LHC Run 3 and beyond
(Master thesis, 2016-11-21)The multiwire proportional chamber signal readout of the ALICE Time Projection Chamber (TPC) will be replaced by Gas Electron Multiplier (GEM) detectors to meet the new requirements due to higher collision rate and energies ... -
CO2 Foam Stabilization with Nanoparticles and EOR in Fractured Carbonate Systems
(Master thesis, 2015-06-18)This thesis is a part of an ongoing study of CO2 foam mobility control in the Reservoir Physics group at the Department of Physics and Technology (IFT) at the University of Bergen. The goal of this thesis was to evaluate ... -
CO2 Injection in Hydrate Bearing Sandstone with Excess Water
(Master thesis, 2013-05-31)It has previously been shown that methane can be produced from gas hydrates by exposing it to carbon dioxide. Since CO2 is the preferred hydrate former below 10 °C it will spontaneously replace CH4 as the guest molecule ... -
CO2 injeksjon for økt oljeutvinning i kalk
(Master thesis, 2013-05-31)Denne masteroppgaven studerer CO2 injeksjon for økt oljeutvinning i kalkstein, og hvordan parametere som sprekker, initielt vann og mobilitetskontroll påvirker oljeproduksjon. Det ble gjennomført 15 eksperimenter med ... -
CO2-injeksjon i Utsiraformasjonen - et studie av CO2/vann-kontakten og temperaturavhengige parametere
(Master thesis, 2012-06-01)Since the start-up in 1996 over 15 Mt CO2 have been injected in to the geological formation Utsira at the commercial CO2 storage project Sleipner. The propagation of CO2 in the reservoir has been monitored by time-lapse ... -
Combined thickness and permittivity measurement of layers using an open-ended coaxial probe
(Master thesis, 2018-06-11)The purpose of this thesis is to develop a method for estimating both the thickness and permittivity of layers simultaneously utilizing an open-ended coaxial probe. One possible application of this method is the detection ... -
