Modeling Thermomechanical Stress with H13 Tool Steel Material Response for Rolling Die under Hot Milling
(Peer reviewed; Journal article, 2019)For the extreme pressure and temperature arising in the hot rolling process, thermomechanical (TM) models are used to predict the residual stresses on the surface of the die because a quantification of the TM stresses ... -
Inspection planning for fatigue cracks in offshore structures by Monte Carlo simulations
(Peer reviewed; Journal article, 2019)Probability-informed inspection planning has traditionally a tendency to produce longer inspection intervals for older structures in contrast with the intuitive assumption that shorter inspection intervals are needed. In ... -
Fatigue design challenges: Recent linear and nonlinear models
(Peer reviewed; Journal article, 2019)Reliable fatigue design rules affect the proactive identification of safety parameters in engineering structures. Numerous fatigue crack initiation and propagation models, linear and nonlinear, have been developed for ... -
Effect and consequence analysis of expanding PIN-technology in various types of heavy machinery
(PhD thesis UiS;, Doctoral thesis, 2023)Expanding pin systems can be applied in any joint, moveable, or fixed, in any type of machine, crane, or equipment, in almost any type of industry, globally. There are a variety of different versions of expanding pins ... -
Ei investeringsanalyse i automatisert grading av støypegods for Bergen Engines AS.
(Master thesis, 2022)Bergen Engines AS har i fleire år hatt eit ynskje om å automatisere grading av støypegods. Ein har tidlegare utført konseptarbeid og innhenta kostnader, men av ulike årsaker har det ikkje vorte utført ei finansiell vurdering ... -
Bygge en blokkjede i TrustZone ved hjelp av Rust
(Bachelor thesis, 2022)Mange moderne prosessorer har sikkerhetsmekanismer som letter opprettelsen av et Trusted Execution Environment (TEE), som er isolert fra det generelle operativsystemet. Personvern- og integritetsutfordringer oppstår i ... -
Solvent-Free Electrode Fabrication Based on Polytetrafluoroethylene Fibrillation for Lithium-ion Batteries
(PhD Theses;883, Doctoral thesis, 2023)The commercial lithium-ion batteries (LiBs) electrodes are manufactured with slurry casting (SC) procedure, where a large amount of energy is consumed, increasing the manufacturing cost a lot. In addition, the SC procedure ... -
Outcrop-scale fracture analysis and seismic modelling of a basin-bounding normal fault in platform carbonates, central Italy
(Peer reviewed; Journal article, 2022)Faults are characterized by a complex internal architecture. In carbonates, the geometry, attitude, and distribution of fault-related fractures and subsidiary faults can largely affect the petrophysical properties and hy ... -
Synthetic natural gas production from CO2 and renewable H2: Towards large-scale production of Ni–Fe alloy catalysts for commercialization
(Peer reviewed; Journal article, 2020-08)Synthetic natural gas (SNG) is one of the promising energy carriers for the excessive electricity generated from variable renewable energy sources. SNG production from renewable H2 and CO2 via catalytic CO2 methanation has ... -
Chemical equilibration in weakly coupled QCD
(Peer reviewed; Journal article, 2019)We study thermalization, hydrodynamization, and chemical equilibration in out-of-equilibrium quark-gluon plasma starting from various initial conditions using QCD effective kinetic theory, valid at weak coupling. In ... -
A laboratory scale approach to wettability restoration in chalk core samples
(Peer reviewed; Journal article, 2019)Wettability in chalk has been studied comprehensively to understand fluid flow mechanisms impacting coreflooding experiments. Wettability becomes paramount in understanding the parameters influencing chalk-fluid interactions. ... -
’All we have to do is be uncertain’: assessing the ‘amplification of institutional incertitude’ in European food safety and risk governance
(Peer reviewed; Journal article, 2022)This paper addresses efforts made by the European Food Safety Authority (EFSA) in recent years to foreground the identification, representation, and public disclosure of scientific uncertainty in its risk assessment ... -
Concerns to Be Considered During Recycling Operations
(Peer reviewed; Journal article, 2019)Recycling should in principle be the goal in all aspects of society. There are, however, limitations, as any recycling task may lead to pollution in the ground, water or air. In the most extreme case, recycling may lead ... -
Hepcidin predicts 5-year mortality after community-acquired pneumonia
(Peer reviewed; Journal article, 2022)Background Virtually all living organisms, including microbes and humans, depend on iron to survive and grow. During an infection, the plasma level of iron and several iron-related proteins change substantially. We ... -
The correlation and determination matrices associated with the burst design of a subsea carbon-fibre-epoxy composite flow-line
(Peer reviewed; Journal article, 2019)This paper examines the correlation and determination matrices of the burst design in a subsea carbon-fibre-epoxy composite flow-line. A case study of a 4" flow-line is investigated. The correlation and determination ... -
Numerical simulation of flow around two 5:1 rectangular cylinders at a high Reynolds Number
(Peer reviewed; Journal article, 2019)The unsteady flows around two stationary rectangular cylinders with a chord-to-thickness ratio of B/D = 5 at ReD = 2 × 105 (based on the free stream velocity and the width length D), are investigated using two-dimensional ... -
Ultra-deep whole genome bisulfite sequencing reveals a single methylation hotspot in human brain mitochondrial DNA
(Peer reviewed; Journal article, 2022)While DNA methylation is established as a major regulator of gene expression in the nucleus, the existence of mitochondrial DNA (mtDNA) methylation remains controversial. Here, we characterized the mtDNA methylation landscape ... -
Chiral soliton lattice in QCD-like theories
(Peer reviewed; Journal article, 2019)Recently, it has been shown that the ground state of quantum chromodynamics (QCD) in suffciently strong magnetic fields and at moderate baryon number chemical potential carries a crystalline condensate of neutral pions: ... -
Anomaly-Induced Inhomogeneous Phase in Quark Matter without the Sign Problem
(Peer reviewed; Journal article, 2019)We demonstrate the existence of an anomaly-induced inhomogeneous phase in a class of vectorlike gauge theories without the sign problem, thus disproving the long-standing conjecture that the absence of the sign problem ... -
Spectral function for overoccupied gluodynamics from classical lattice simulations
(Peer reviewed; Journal article, 2019)We study the spectral properties of an overoccupied gluonic system far from equilibrium. Using classical Yang–Mills simulations and linear response theory, we determine the statistical and spectral functions. We measure ...
