• #### Influence of Residual Oil on Polymer Injectivity ﻿

(The University of Bergen, 2017-06-22)
Because a significant fraction of the world’s light oil reservoirs has already been produced, the technical and economic challenges of developing heavy oil fields is now unavoidable [1]. Water flooding has proven to be a ...

• #### Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at $\sqrt{s}=7$ TeV ﻿

(Springer, 2017-08)
Two-particle angular correlations were measured in pp collisions at $\sqrt{s} = 7$ TeV for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. Data for mesons exhibit an expected ...

• #### Instrumentering av eksperimentell vannkolonne for studier av mikroalgers vertikalforflytning ﻿

(The University of Bergen, 2013-05-31)
Alger er viktig som primærprodusent i det marine økosystem. Det er derfor viktig at det oppnås større forståelse for hvordan alger lever og dør. For å kunne oppnå denne forståelsen må det gjøres tester og eksperimenter ...

• #### Integration and design for the ALICE ITS readout chain ﻿

(The University of Bergen, 2018-06-26)
ALICE and its Inner Tracking System detector in the LHC at CERN will undergo a major upgrade during its second long shutdown taking place in 2019 and 2020. New silicon sensors called ALPIDE will be utilized, which requires ...

• #### Intensity asymmetries in the dusk sector of the poleward auroral oval due to IMF Bx ﻿

(WileyAmerican Geophysical Union, 2014-12)
In the exploration of global-scale features of the Earth's aurora, little attention has been given to the radial component of the Interplanetary Magnetic Field (IMF). This study investigates the global auroral response in ...
Journal article
• #### The interaction between transpolar arcs and cusp spots ﻿

(AGU Publications, 2015-11-25)
Transpolar arcs and cusp spots are both auroral phenomena which occur when the interplanetary magnetic field is northward. Transpolar arcs are associated with magnetic reconnection in the magnetotail, which closes magnetic ...

Doctoral thesis
• #### Interatom intrashell blockade ﻿

(American Physical Society, 2011-01-07)
We demonstrate a feature of the Rydberg blockade mechanism which occurs between two initially excited circular Rydberg atoms. When both atoms are exposed to weak time-dependent electric fields, it is shown that the ...

• #### Interface Design for the Gigabit Transceiver Common Readout Unit ﻿

(The University of Bergen, 2016-06-01)
The future upgrade of the Large Hadron Collider accelerator, the High-Luminosity LHC, has its goal of increasing the beam luminosity by ten times. This will lead to a corresponding growth of the amount of data to be ...
Master thesis
• #### Interpretation of geometrical effects in consequence modelling. Comparison study between the commercial consequence assessment tools FLACS and PHAST for flammable gas dispersion ﻿

(The University of Bergen, 2014-04-02)
Computational fluid dynamics and integral consequence modeling is today a crucial part of safety assessments worldwide. The models are widely used to predict the effects of ventilation patterns, hazardous gas dispersion, ...
Master thesis
• #### Invariant Mass Distributions of SUSY Cascade Decays ﻿

(The University of Bergen, 2011-06-01)
If supersymmetry (SUSY) is realised at experimental energies and R-parity is conserved, sparticles might be produced and decay in cascades at the LHC. A neutral LSP will escape detection, complicating the reconstruction ...
Master thesis
• #### Investigating the energy yield of rain cells ﻿

(The University of Bergen, 2018-12-08)
Harvesting energy from rain has been done indirectly for hundreds of years by building dams or reservoirs. Recently, research has been made into gathering energy from individual raindrops. One of the discovered methods ...

• #### Investigating the Role of Coherence Effects on Jet Quenching in Pb-Pb Collisions at $\sqrt{s_{NN}} =2.76$ TeV using Jet Substructure ﻿

(Elsevier, 2017-11)
We report measurements of two jet shapes, the ratio of 2-Subjettiness to 1-Subjettiness ($\it{\tau_{2}}/\it{\tau_{1}}$) and the opening angle between the two axes of the 2-Subjettiness jet shape, which is obtained by ...

• #### Investigation into the impact of solid surfaces in aqueous systems ﻿

(The University of Bergen, 2016-03-03)
Global warming is upon us. The scientiﬁc community is searching for methods of slowing down, preventing and reversing its effects. Carbon dioxide have been at the center of attention the last few decades, being the main ...
Doctoral thesis
• #### Investigation of instability and turbulence effects on gas explosions: experiments and modelling ﻿

(The University of Bergen, 2018-03-09)
Safe design of industrial facilities requires models that can predict the consequences of accidental gas explosions in complex geometries with sufficient accuracy. Computa- tional fluid dynamics (CFD) models are widely ...
Doctoral thesis
• #### Investigation of Low Salinity Polymer and Surfactant Flooding in Carbonate Reservoir at Reservoir Conditions ﻿

(The University of Bergen, 2018-04-20)
It is estimated that 40-60% of the world’s total hydrocarbon production is from carbonate rocks [1]. Carbonate rocks contain the world`s largest fields in the Middle East (i.e., Ghawar Field, Saudi Arabia). Waterflooding ...
