CFD simulations of a suspension bridge deck for different deck shapes with railings and vortex mitigating devices
(Peer reviewed; Journal article, 2019)Aerodynamic response of a single-box suspension bridge girder is investigated using CFD simulations. The importance of including railings and vortex mitigating devices such as guide vanes and a spoiler in the simulations ... -
Use of simulator training to mitigate risks in arctic shipping operations
(Peer reviewed; Journal article, 2019)Over the recent years, ship traffic in the polar areas has increased. There is reason to believe that this traffic, and especially the cruise traffic, will increase further as the ice retracts towards the poles. There is ... -
Design of steel bridge girders against ship forecastle collisions
(Peer reviewed; Journal article, 2019-10)A key aspect in the design of mega bridge structures across navigable waterways is to ensure bridge safety with respect to accidental ship collisions. Special attention has been paid to providing sufficient impact resistance ... -
Offshore Wind Turbine Loads and Motions in Unstable Atmospheric Conditions
(Peer reviewed; Journal article, 2019)Even though it is widely known that unstable atmospheric stability conditions can lead to higher turbulence, the use of proper turbulent wind models considering unstable conditions are not often used in the simulation of ... -
A Game Theoretic Model of Adversaries and Media Manipulation
(Peer reviewed; Journal article, 2019)A model is developed for two players exerting media manipulation efforts to support each of two actors who interact controversially. Early evidence may support one actor, while the full evidence emerging later may support ... -
Transmission in pseudospin-1 and pseudospin-3/2 semimetals with linear dispersion through scalar and vector potential barriers
(Peer reviewed; Journal article, 2020-09)We investigate the tunneling of pseudospin-1 and pseudospin-3/2 quasiparticles through a barrier consisting of both electrostatic and vector potentials, existing uniformly in a finite region along the transmission axis. ... -
Highly occupied gauge theories in 2+1 dimensions: A self-similar attractor
(Peer reviewed; Journal article, 2019-11)Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar ... -
Bottomonium suppression at RHIC and LHC
(Peer reviewed; Journal article, 2019-02)The strong suppression of heavy quarkonia is a good indicator that one has generated a quark-gluon plasma (QGP) in an ultrarelativistic heavy ion collision. Recent advancements in first principles calculations of the heavy ... -
Hvordan benytter universiteter og høyskoler risikoanalyser som beslutningsstøtte for å sikre seg mot tilsiktede uønskede hendelser?
(Masteroppgave/UIS-TN-ISØP/2020;, Master thesis, 2020-12)Universitets og høyskolesektoren (UH-sektoren) i Norge får føringer fra kunnskapsdepartementet for hvordan arbeidet med samfunnssikkerhet og beredskap skal prioriteres, og herunder bruk av risikoanalyser som verktøy ... -
Analytic structure of nonhydrodynamic modes in kinetic theory
(Peer reviewed; Journal article, 2019-09)How physical systems approach hydrodynamic behavior is governed by the decay of nonhydrodynamic modes. Here, we start from a relativistic kinetic theory that encodes relaxation mechanisms governed by different timescales ... -
Lattice study of static quark-antiquark interactions in dense quark matter
(Peer reviewed; Journal article, 2019-05)In this paper we study the interactions among a static quark-antiquark pair in the presence of dense two-color quark matter with lattice simulation. To this end we compute Polyakov line correlation functions and determine ... -
S-N curve for riveted details in corrosive environment and its application to a bridge
(Peer reviewed; Journal article, 2020-01)A formula for stress‐life curve is proposed to predict the fatigue life of riveted bridges located in corrosive environments. The corrosive environment‐dependent parameters of the S‐N curve are determined based on the ... -
Problem and models of multicriteria decision making and risk assessment of the arctic offshore oil and gas field development
(Peer reviewed; Journal article, 2019)The article is devoted to the systematic solution of problems of multi-criteria assessment and the possibility of implementing projects for the development of hydrocarbon deposits on the Arctic shelf under conditions of ... -
Predictive maintenance (PdM) analysis matrix: A tool to determine technical specifications for PdM ready-equipment
(Peer reviewed; Journal article, 2019)Predictive maintenance (PdM) and operations optimisation are expected to generate the highest industrial and societal impact within the oil and gas industry. Such an optimistic expectation requires several changes in asset ... -
Scalability and compatibility analyses of airborne wind technology for maritime transport
(Peer reviewed; Journal article, 2019)Wind energy is a source freely available in the oceans. New developments in the wind industry are towards high altitude wind turbines, known as Airborne Wind Energy Systems. The airborne wind technology is rapidly developing ... -
Rhythm Analysis during Cardiopulmonary Resuscitation Using Convolutional Neural Networks
(Peer reviewed; Journal article, 2020-05)Chest compressions during cardiopulmonary resuscitation (CPR) induce artifacts in the ECG that may provoque inaccurate rhythm classification by the algorithm of the defibrillator. The objective of this study was to design ... -
Universal p-form black holes in generalized theories of gravity
(Peer reviewed; Journal article, 2020-10)We explore how far one can go in constructing d-dimensional static black holes coupled to p-form and scalar fields before actually specifying the gravity and electrodynamics theory one wants to solve. At the same time, we ... -
Synthesis and Investigation of Polymers of 2‑Methacrylamido-caprolactam as Kinetic Hydrate Inhibitors
(Peer reviewed; Journal article, 2020-05)Poly(N-vinylcaprolactam) (PVCap) and related copolymers have been used as kinetic hydrate inhibitors (KHIs) for over 25 years to combat gas hydrate formation in oil and gas field production flow lines. The caprolactam ... -
On Universal Black Holes
(Peer reviewed; Journal article, 2020)Recent results on universal black holes in d dimensions are summarized. These are static metrics with an isotropy-irreducible homogeneous base space which can be consistently employed to construct solutions to virtually ... -
Protein phosphatase 2A as a regulator and mediator of beneficial plant-microbe interactions
(PhD thesis UiS;, Doctoral thesis, 2021-03)Protein phosphatase 2A (PP2A) is involved in the regulation of stress response, growth and hormone signalling during the plant life cycle. A variety of plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhiza ...
