Gas Hydrates in Porous Media: CO2 Storage and CH4 Production
(The University of Bergen, 2014-04-25)Doctoral thesis -
Geo-modeling and fluid flow simulation in paleokarst reservoirs
(The University of Bergen, 2015-06-30)This master thesis focuses on modeling and simulation of fluid flow in collapsed paleocave systems, also known as paleokarst. Petroleum reservoirs all around the world exhibit karst structures. The latest ones on the ...Master thesis -
A giant reconstruction of α-quartz (0001) interpreted as three domains of nano dauphine twins
(Europe PMC, 2015-10-08)Silica (SiO2) is one of the most common materials on Earth. The crystalline form α-quartz is the stable silica polymorph at ambient conditions although metastable forms exist. α-quartz is a piezoelectric material, it can ...Journal article -
The global potential for carbon capture and storage from forestry
(Springer, 2016-02-26)Background: Discussions about limiting anthropogenic emissions of CO2 often focus on transition to renewable energy sources and on carbon capture and storage (CCS) of CO2. The potential contributions from forests, forest ...Journal article -
Global Λ polarization in high energy collisions
(American Physical Society, 2017-03-14)With a Yang-Mills flux-tube initial state and a high-resolution (3+1)D particle-in-cell relativistic (PICR) hydrodynamics simulation, we calculate the Λ polarization for different energies. The origination of polarization ...Journal article -
A Golden-Channel Higgs Decay
(The University of Bergen, 2011-06-01)With a Higgs mass greater than 190 GeV and lower than 300 GeV, the decay channel H --> ZZ --> 4l becomes what is referred to as the golden channel for Higgs decay (clean signal). Suppose a pair of on shell Zs with ...Master thesis -
GPS scintillation and irregularities at the front of an ionization tongue in the nightside polar ionosphere
(WileyAmerican Geophysical Union, 2014-10)In this paper we study a tongue of ionization (TOI) on 31 October 2011 which stretched across the polar cap from the Canadian dayside sector to Svalbard in the nightside ionosphere. The TOI front arrived over Svalbard ...Journal article -
GPS scintillations associated with cusp dynamics and polar cap patches
(EDP Sciences, 2017)This paper investigates the relative scintillation level associated with cusp dynamics (including precipitation, flow shears, etc.) with and without the formation of polar cap patches around the cusp inflow region by the ...Journal article -
Gravitino dark matter and the flavour structure of R-violating operators
(Elsevier, 2009-06-15)We study gravitino dark matter and slow gravitino decays within the framework of R-violating supersymmetry, with particular emphasis on the flavour dependence of the branching ratios and the allowed R-violating couplings. ...Journal article -
Gravitino Dark Matter with Entropy Production constrained by Big Bang Nucleosynthesis
(The University of Bergen, 2016-12-16)We are looking at a gravitino dark matter scenario with a general neutralino next-to-lightest supersymmetric particle. We are considering the primary decay channels of the neutralino, and we define the supersymmetric ...Master thesis -
Grid sensitivity simulation of low salinity and polymer flooding
(The University of Bergen, 2015-05-31)Water flooding in a reservoir is a well- established recovery method used to maintain the reservoir pressure and to displace the oil towards the producing well. However, after water flooding there is still a ...Master thesis -
Ground-based and Satellite Remote Sensing of Atmospheric Aerosols and Ultraviolet Solar Radiation
(The University of Bergen, 2016-04-08)Satellite remote sensed data have been used to determine the aerosol climatology and to investigate the influence of the aerosol index (AI) on the ultraviolet (UV) index in coastal land areas in Serrekunda (13.28◦ N, 16.34◦ ...Doctoral thesis -
The Hall current system revealed as a statistical significant pattern during fast flows
(European Geosciences Union, 2008-11-05)We have examined the dawn-dusk component of the magnetic field, BY , in the night side current sheet during fast flows in the neutral sheet. 237 h of Cluster data from the plasma sheet between 2 August 2002 and 2 October ...Journal articlePeer reviewed -
Heavy flavor azimuthal correlations in PYTHIA generated proton-proton collisions at LHC energies
(The University of Bergen, 2014-11-20)The ALICE detector at CERN is a promising tool for the study of the Quark-Gluon Plasma (QGP), an exotic state of matter thought to be present in the early Universe. The study of partonic energy loss reveals vital information ...Master thesis -
Heterogeneous distributed calibration framework for the high level trigger in ALICE
(The University of Bergen, 2009-02-13)This thesis focusses on the development of a distributed and re-configurable online calibration environment for the ALICE (A Large Ion Collider Experiment) HLT (High Level Trigger). ALICE1 is one of the four major ...Doctoral thesis -
Heterogeneous Hydrate Nucleation on Calcite {1014} and Kaolinite {001} Surfaces: A Molecular Dynamics Simulation Study
(The University of Bergen, 2016-06-01)Natural gas hydrates are of significant interest due to the great amount of methane that can potentially be utilised as an energy source. These methane resources are trapped in ice-like form, which is a concern ...Master thesis -
The Higgs Boson in Less Constrained Supersymmetric Models
(The University of Bergen, 2012-06-01)In this thesis, we explore the phenomenological minimal supersymmetric standard model (pMSSM) in the context of the Higgs boson. If the emerging results from the LHC are real, will the pMSSM be able to accommodate this? ...Master thesis -
The Higgs-like boson spin from the center–edge asymmetry in the diphoton channel at the LHC
(Springer, 2015-05-07)We discuss the discrimination of the 125 GeV spin-parity 0+ Higgs-like boson observed at the LHC, decaying into two photons, H→γγ, against the hypothesis of a minimally coupled JP=2+ narrow diphoton resonance with the same ...Journal article -
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 ...Master thesis
