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 ... -
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 ... -
Numerical Modeling of Supercritical ‘Out-Salting’ in the “Atlantis II Deep” (Red Sea) Hydrothermal System
(Peer reviewed; Journal article, 2007)Supercritical water behaves close to that of a non-polar fluid and its ability to dissolve salt ions is very low. In rifting locations world-wide, where hot vents occur, it has been shown that seawater attains supercritical ... -
A seismic field test with a Low level Acoustic Combustion Source and Pseudo Noise codes
(Journal article, 2007-01-20)The Low level Acoustic Combustion Source (LACS) is a new type of pulsed underwater acoustic source with an output level of 0.5-1.0 barm peak to peak. The source is based on a combustion engine and intended for shallow ... -
Wettability effects on oil recovery mechanisms in fractured chalk
(Doctoral thesis, 2007-02-02)This thesis is a part of the ongoing project, “Oil recovery from fractured chalk reservoirs”, which is a collaboration between the Reservoir Physics Group at the University of Bergen and ConocoPhillips Research Center in ... -
The effect of energetic electron precipitation on the nitric oxide density in the lower thermosphere

Marine seismics with a pulsed combustion source and Pseudo Noise codes
(Peer reviewed; Journal article, 2007-03)There has been an ongoing debate for years of how dangerous seismic surveys are with respect to marine life. Marine seismics is today dominated by airgun technology, where high energy is generated by a release of compressed ... -

Charged Higgs boson searches and SemiConductor Tracker commissioning for the ATLAS experiment
(Doctoral thesis, 2007-06-21)The ATLAS (A Toroidal Lhc ApparatuS) experiment is one of four major experiments presently being installed at the upcoming Large Hadron Collider (LHC) at the European Centre for Nuclear Research (CERN) outside Geneva. In ... -
Cluster observations of a field aligned current at the dawn flank of a bursty bulk flow
(Peer reviewed; Journal article, 2007-06-29)This article describes observations of a bursty bulk flow (BBF) in the outer central plasma sheet. The observations are made with the Cluster satellites, located approximately 19RE downtail, close to the midnight sector ... -
Nuclear modification factor for charged pions and protons at forward rapidity in central Au plus Au collisions at 200 GeV
(Peer reviewed; Journal article, 2007-07)We present spectra of charged pions and protons in 0–10% central Au + Au collisions at View the MathML sourcesNN=200 GeV at mid-rapidity (y=0y=0) and forward pseudorapidity (η=2.2η=2.2) measured with the BRAHMS experiment ... -

Neutral atom and molecule focusing using a Fresnel zone plate
(Peer reviewed; Journal article, 2008)Focusing of neutral atoms and molecules has several potential applications. The very first microscopy images using helium as an imaging probe were published earlier this year. Another possible application is to study the ... -
Modelling of vented dust explosions – empirical foundation and prospects for future validation of CFD codes
(IChemE Symposium Series;154, Chapter; Peer reviewed, 2008)Explosion venting is the most frequently used method for mitigating the effects from accidental dust explosions in the process industry. Optimal design of vent systems and credible execution of risk assessments in powder ... -
Search for SUSY signals with tau leptons in the ATLAS detector
(Master thesis, 2008-02-15)The main topic of this thesis is the study of the discovery potential of the ATLAS detector for SUSY, by considering a supersymmetric decay chain involving two tau leptons. In supersymmetric models where R-parity is ... -
