Signal mixture estimation for degenerate heavy Higgses using a deep neural network
(Peer reviewed; Journal article, 2018-12)If a new signal is established in future LHC data, a next question will be to determine the signal composition, in particular whether the signal is due to multiple near-degenerate states. We investigate the performance of ... -
A Silicon Photomultiplier Based Readout System For A Cosmic Muon Telescope; Design And Implementation
(Master thesis, 2017-06-16)The Cosmic Ray Telescope (CRT) is a 4 m^2 scintillator detector segmented into 16 slabs with dimensions of 25100 cm^2. The detector is located at the Department of Physics, University of Bergen, and is intended primarily ... -
A simple method to detect spontaneous CP violation in multi-Higgs models
(Peer reviewed; Journal article, 2017-08)For models with several Higgs doublets we present an alternative method to the one proposed by Branco, Gerard and Grimus, in 1984, to check whether or not CP is spontaneously violated in the Higgs potential. The previous ... -
Simplified modelling of explosion propagation by dust lifting in coal mines
(Chapter; Peer reviewed, 2007)Dispersion of accumulated layers of combustible dust by turbulent flow or shock waves ahead of the propagating flame may sustain explosion propagation in coal mine galleries and other industrial facilities. The mechanisms ... -
Simualtion of Three-phase Flow in Porous Media Including Capillary Pressure Representing Variation in Rock Wettability
(Conference lecture, 2011-04-12) -
Simulated seasonal impact on middle atmospheric ozone from high-energy electron precipitation related to pulsating aurorae
(Journal article; Peer reviewed, 2021)Recent simulation studies have provided evidence that a pulsating aurora (PsA) associated with high-energy electron precipitation is having a clear local impact on ozone chemistry in the polar middle mesosphere. However, ... -
Simulating the Effect of Release of Pressure and Dust Lifting on Coal Dust Explosions
(Conference lecture, 2007)Dispersion of accumulated layers of combustible dust by turbulent flow or shock waves ahead of a propagating flame can play an important role for explosion propagation in coal mines. In 1924, Greenwald and Wheeler investigated ... -
Simulating the Influence of Obstacles on Accelerating Dust and Gas Flames

Simulating vented hydrogen deflagrations: Improved modelling in the CFD tool FLACS-hydrogen
(Journal article; Peer reviewed, 2021)This paper describes validation of the computational fluid dynamics tool FLACS-Hydrogen. The validation study focuses on concentration and pressure data from vented deflagration experiments performed in 20-foot shipping ... -
Simulation and modelling of water spray in the 3D explosion simulation program FLACS
(Master thesis, 2004)In a gas processing plant and in offshore platforms a gas explosion could have serious consequences, and it is therefore essential to have mitigation systems that can prevent and/or reduce unwanted scenarios. One such ... -
Simulation of Enhanced Heavy Oil Recovery: History Match of Waterflooding and Polymer injection at Adverse Mobility Ratio
(Master thesis, 2015-06-01)Waterflooding and polymer flooding total recovery in the unstable immiscible displacement is very attractive and its applications are interesting in recent years. However, the simulation models of unstable immiscible ... -
Simulation of geomechanical effects of CO2 injection in cold aquifers with possibility of hydrate formation
(Chapter; Peer reviewed, 2011)The injection of CO2 in saline aquifers can have a significant impact on the geochemistry and the geo-mechanics of the reservoirs. Due to this injection, minerals will dissociate in regions with low pH or precipitate in ... -
Simulation of hydrate dynamics in reservoirs
(Chapter; Peer reviewed, 2011)Gas hydrates in reservoirs are generally not in thermodynamic equilibrium and there may be several competing phase transitions involving hydrate. Formation of carbon dioxide hydrates during aquifer storage of carbon dioxide ... -
Simulation of Nanoparticle-Stabilized CO2-Foam in Sandstone
(Master thesis, 2019-09-24) -
Simulation of prompt gamma production in particle therapy and beam trajectory imaging
(Master thesis, 2015-06-01)In cancer oncology, using of Mega electron Volt (MeV) bremsstrahlung photons has been clinically practised on cancer patients since photons can deliver a significant dose to tumour volumes when projected into the body in ... -
Simulation of viscous instabilities in miscible and immiscible displacement
(Master thesis, 2008-06-09)This study includes modeling of viscous instabilities at both miscible and immiscible displacement. Oil recovery of heavy oil leads to unstable displacement for adverse mobility ratio for both miscible and immiscible ... -
Simulation Study of In-Situ Polymer Rheology in a Radial Flow Experiment
(Master thesis, 2018-06-27)The global energy demand is continuously growing, and even though renewable energy sources are becoming increasingly important, oil remains the leading energy fuel to this date, accounting for one third of the consumption. ... -
Simulation Study of Polymer Injectivity and Rheology in Radial Models
