W and Z boson production in p–Pb collisions at \(\sqrt{s_{\rm NN}}=5.02\) TeV
(Peer reviewed; Journal article, 2017-02)The W and Z boson production was measured via the muonic decay channel in proton-lead collisions at \(\sqrt{s_{\rm NN}}=5.02\) TeV at the Large Hadron Collider with the ALICE detector. The measurement covers backward ... -
A water droplet-powered sensor based on charge transfer to a flow-through front surface electrode
(Journal article; Peer reviewed, 2020)A water droplet sensor based on a flow-through front surface electrode is demonstrated. It is shown that a triboelectric nanogenerator based on a metal-dielectric junction can be utilized to construct simple, self-powered ... -
Water shutoff and conformance improvement: an introduction
(Journal article; Peer reviewed, 2021)This paper provides an introduction to the topic of water shutoff and conformance improvement. After indicating the volumes of water produced during oilfield operations, a strategy is provided for attacking excess water ... -

Weinberg’s 3HDM potential with spontaneous CP violation
(Journal article; Peer reviewed, 2023)We study the potential of Weinberg’s Z2×Z2-symmetric three-Higgs-doublet model. The potential is designed to accommodate CP violation in the scalar sector within a gauge theory, while at the same time allowing for natural ... -
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 ... -
Wetting of porous thin films exhibiting large contact angles
(Journal article; Peer reviewed, 2023)Porous solid films that promote large apparent contact angles are interesting systems since their wetting properties are dependent on both the surface structure and water penetration into the film. In this study, a ... -
What Determines the Parameters of a Propagating Streamer: A Comparison of Outputs of the Streamer Parameter Model and of Hydrodynamic Simulations
(Journal article; Peer reviewed, 2021)Electric streamer discharges (streamers) in the air are a very important stage of lightning, taking place before formation of the leader discharge, and with which an electric discharge starts from conducting objects which ... -
What is the appropriate coordinate system for magnetometer data when analyzing ionospheric currents?
(Peer reviewed; Journal article, 2014-10)In this paper we investigate which coordinate representation is most appropriate when analyzing ground magnetometer data in terms of ionospheric currents, in particular the westward electrojet. The AL and the recently ... -
Why should we use residual thermodynamics for calculation of hydrate phase transitions?
(Journal article; Peer reviewed, 2020)The formation of natural gas hydrates during processing and transport of natural has historically been one of the motivations for research on hydrates. In recent years, there has been much focus on the use of hydrate as a ... -
Will Climate Change Impact Polar NOx Produced by Energetic Particle Precipitation?
(Journal article; Peer reviewed, 2020)Energetic electron precipitation (EEP) is an important source of polar nitrogen oxides (NOx) in the upper atmosphere. During winter, mesospheric NOx has a long chemical lifetime and is transported to the stratosphere by ... -
Wilson line correlators beyond the large-Nc
(Journal article; Peer reviewed, 2021)We study hard 1 → 2 final-state parton splittings in the medium, and put special emphasis on calculating the Wilson line correlators that appear in these calculations. As partons go through the medium their color continuously ... -
