An improved workflow for image and laserbased virtual geological outcrop modelling
(The University of Bergen, 20130315)Photorealistic 3D models, representing an object’s surface geometry textured with conventional photography, are used for visualization, interpretation and spatial measurement in many disparate fields, such as cultural ...Doctoral thesis 
Improvements and extensions to the configuration tools of the TaskManager HLT software in the ALICE experiment at CERN
(The University of Bergen, 2007)This thesis concerns work done to improve andextend software that is used to configure nodesand trigger software in HLT under the ALICEexperiment at CERN. HLT is a large computercluster that will be used to reduce data ...Master thesis 
Improving Efficiency in Parameter Estimation Using the Hamiltonian Monte Carlo Algorithm
(The University of Bergen, 2008)This thesis investigates three approaches to improve the performance of the Hamiltonian Monte Carlo algorithm. The first approach enhances the Hamiltonian Monte Carlo by suppressing random walk in the Gibbs sampling using ...Master thesis 
Improving Parallel Sparse Matrixvector Multiplication
(The University of Bergen, 20131219)Sparse Matrixvector Multiplication (SMvM) is a mathematical technique encountered in many programs and computations and is often heavily used. Solving SMvM in parallel allows for bigger instances to be solved, and problems ...Master thesis 
Improving the error rates of the Begg and Mazumdar test for publication bias in fixed effects metaanalysis
(BioMed Central, 20140922)Background: The rank correlation test introduced by Begg and Mazumdar is extensively used in metaanalysis to test for publication bias in clinical and epidemiological studies. It is based on correlating the standardized ...Journal article 
Improving the Nuclear Tracer Imaging Centrifuge Method for Measuring InSitu Capillary Pressures and Comparisons with Other Methods
(The University of Bergen, 2004)Master thesis 
Impulsive overflatekilder for seismisk prospektering
(The University of Bergen, 2003)Master thesis 
In situ fluid dynamics and CO2 injection in porous rocks
(The University of Bergen, 20091218)Understanding multiphase fluid flow in porous rocks implies knowledge of fundamental properties such as wettability, relative permeability and capillary pressure. These parameters, as well as the extent of fractures and ...Doctoral thesis 
In situ hybridisering for deteksjon av cytokrom P450 1A i presisjonskuttede leverskiver (PCLS) fra atlanterhavstorsk (Gadus morhua)
(The University of Bergen, 20160601)Marine arter og økosystemer blir utsatt for menneskeskapte stoffer fra en rekke ulike kilder. Siden de biologiske effektene for mange av disse stoffene ikke er godt karakterisert er det derfor behov for gode og effektive ...Master thesis 
In the dark: a review of ecosystem processes during the Arctic polar night
(Elsevier Ltd., 20150828)Several recent lines of evidence indicate that the polar night is key to understanding Arctic marine ecosystems. First, the polar night is not a period void of biological activity even though primary production is close ...Journal article 
Inflight calibration of NOAA POES proton detectors  Derivation of the MEPED correction factors
(Wiley, 20151125)The MEPED instruments on board the NOAA POES and MetOp satellites have been continuously measuring energetic particles in the magnetosphere since 1978. However, degradation of the proton detectors over time leads to an ...Journal article 
The Inclusion Problem for Regular Expressions
(Springer, 2010)This paper presents a new polynomialtime algorithm for the inclusion problem for certain pairs of regular expressions. The algorithm is not based on construction of finite automata, and can therefore be faster than the ...Peer reviewedChapter 
Inclusive photon production at forward rapidities in protonproton collisions at $\sqrt{s}$ = 0.9, 2.76 and 7 TeV
(Springer Berlin Heidelberg, 20150409)The multiplicity and pseudorapidity distributions of inclusive photons have been measured at forward rapidities ($2.3 < \eta < 3.9$) in protonproton collisions at three centerofmass energies, $\sqrt{s}=0.9$, 2.76 and 7 ...Journal article 
Inclusive singleparticle production in twophoton collisions at LEP II with the DELPHI detector
(Elsevier, 200908)A study of the inclusive charged hadron production in twophoton collisions is described. The data were collected with the DELPHI detector at LEP II. Results on the inclusive singleparticle p_T distribution and the ...Journal article 
Inclusive, prompt and nonprompt J/ψ production at midrapidity in PbPb collisions at √sNN = 2.76 TeV
(Springer, 20150710)The transverse momentum (p T) dependence of the nuclear modification factor R AA and the centrality dependence of the average transverse momentum 〈p T〉 for inclusive J/ψ have been measured with ALICE for PbPb collisions ...Journal article 
Incompleteness of the Inference System BNeg
(The University of Bergen, 20160531)Any propositional discourse can be represented as a propositional theory in a specific form in such a way that the theory is inconsistent if and only if the discourse is paradoxical. Propositional theories in this form ...Master thesis 
Increased ventilation of Antarctic deep water during the warm midPliocene
(Nature Publishing Group, 20130219)The midPliocene warm period is a recent warm geological period that shares similarities with predictions of future climate. It is generally held the midPliocene Atlantic Meridional Overturning Circulation must have been ...Journal article 
Increasing the levels of the essential trace elements Se, Zn, Cu and Mn in rotifers (Brachionus plicatilis) used as live feed
(Elsevier, 20130304)Rotifers are a common first feeding diet for rearing marine fish larvae. However, the levels of Mn, Cu, Zn, Se and iodine found in rotifers are low and may be insufficient to meet larval fish requirements. This study ...Journal article 
Independent Set on P5free graphs, an empirical study
(The University of Bergen, 20151120)We implement the recent polynomial time algorithm for the independent set problem on P5free graphs, and study the performance of this algorithm on graphs of size up to 50. Our empirical results show that the algorithm ...Master thesis 
The index tracking problem with a limit on portfolio size
