Results from the intercalibration of optical low light calibration sources 2011
(Peer reviewed; Journal article, 2012-05-03)Following the 38th Annual European Meeting on Atmospheric Studies by Optical Methods in Siuntio in Finland, an intercalibration workshop for optical low light calibration sources was held in Sodankylä, Finland. The main ... -
Results of the Electron Drift Instrument on Cluster
(Journal article; Peer reviewed, 2021)The electron drift instrument (EDI) on Cluster pioneered a new method of measuring electric fields, using a beam of electrons to sample the drift velocity over a km-scale gyro orbit. The technique is especially well suited ... -
Retrieval practice of a hierarchical principle structure in university introductory physics: Making stronger students
(Journal article; Peer reviewed, 2020)Introductory physics is taught to several hundred thousand university students every year. It is seen as especially difficult by many and the failure rate is often high. A relevant question is whether one can increase the ... -
A Review of Polymer Gel Utilization in Carbon Dioxide Flow Control at the Core and Field Scale
(Journal article; Peer reviewed, 2023)Polymer gel has been used for water conformance control for several decades and may have significant potential in remediating unfavorable carbon dioxide (CO2) flow in the subsurface. High-mobility CO2 may channel quickly ... -
Revisiting transverse momentum broadening in dense QCD media
(Journal article; Peer reviewed, 2021)We reconsider the problem of transverse momentum broadening of a highly energetic parton suffering multiple scatterings in dense colored media, such as the thermal quark-gluon plasma or large nuclei. In the framework of ... -
Rheological properties of hydrophobically modified anionic polymers: The effect of varying salinity in polymer solution
(Master thesis, 2017-06-16)A new class of polymers, named ‘hydrophobically modified water-soluble polymers’, has been developed as an alternative to the more commonly used polyelectrolytes in enhanced oil recovery (EOR) applications. These polymers ... -
Rheology of Synthetic Polymers in Porous Media
(Master thesis, 2014-06-02)This master thesis is written out of the Centre for Integrated Petroleum Research (UNI CIPR) at the University of Bergen (UiB). The aim of this study has been to describe the polymer rheology of the high molecular weight ... -
Risiko for spredning av flammer og røyk gjennom brannskiller ved endringer i bruk av sprinkler og røykkontroll i boligkvarter på petroleumsinnretninger.
(Master thesis, 2016-09-27)Målet med oppgaven har vært å undersøke hvordan endringer i bruk av sprinkler og brannspjeld i boligkvarter på petroleumsinnretninger, har påvirket risiko for spredning av flammer og røyk gjennom ventilasjonskanaler. ... -
The Role of Resistivity on the Efficiency of Magnetic Reconnection in MHD
(Journal article; Peer reviewed, 2022)Using a resistive MagnetoHydroDynamic (MHD) simulation, we study how the magnitude and shape of diffusion influence magnetic reconnection. Specifically, we investigate how and why the reconnection rate is influenced by ... -
The Role of Safety in the Framing of the Hydrogen Economy by Selected Groups of Stakeholders
(Journal article; Peer reviewed, 2022)While the international discourse on the hydrogen economy tends to focus on the importance of enabling the transition from fossil to renewable energy sources and the prospects for innovation and value creation, the ... -
Room-Scale CO2 Injections in a Physical Reservoir Model with Faults
(Journal article; Peer reviewed, 2024)We perform a series of repeated CO2 injections in a room-scale physical model of a faulted geological cross-section. Relevant parameters for subsurface carbon storage, including multiphase flows, capillary CO2 trapping, ... -
Rotation and Polarization in Heavy Ion Collisions

Rotation and Turbulence in Peripheral Heavy Ion Collisions
(Doctoral thesis, 2014-12-16)In our computational fluid dynamics (CFD) calculations the Kelvin-Helmholtz instability (KHI) starts to develop in peripheral collisions. At high energies the shear viscosity of the Quark Gluon Plasma (QGP) flow is becoming ... -
Rotation and Turbulent Instability in Peripheral Heavy Ion Collisions
(Journal article; Peer reviewed, 2014-04-29)In recent years fluid dynamical processes became a dominant direction of research in high energy heavy ion reactions. The Quark-gluon Plasma formed in these reactions has low viscosity, which leads to significant fluctuations ... -
Rotation in an exact hydrodynamical model
(Peer reviewed; Journal article, 2014-08-01)We study an exact and extended solution of the fluid dynamical model of heavy ion reactions and estimate the rate of slowing down of the rotation due to the longitudinal and transverse expansion of the system. The initial ... -
Rydberg Atoms in THz Fields
(Master thesis, 2015-11-17)Rydberg atoms are highly excited atoms with bizarre and exotic properties such as huge orbits and exaggerated sensitivity to fields. In this study we examine these atoms using classical methods. We present the classical ... -
S3-inspired three-Higgs-doublet models: A class with a complex vacuum
(Journal article; Peer reviewed, 2020)In this paper we analyze in detail an S3-symmetric three-Higgs-doublet model with a specific vacuum configuration. This analysis allows us to illustrate important features of models with several Higgs doublets, such as the ... -
