Computable conditions for order-2 CP symmetry in NHDM potentials
(Journal article; Peer reviewed, 2024)We derive necessary and sufficient conditions for order-2 CP (CP2) symmetry in N-Higgs-doublet potentials for N>2. The conditions, which are formulated as relations between vectors that transform under the adjoint ... -
Challenges of integrated multi-infrastructure asset management: a review of pavement, sewer, and water distribution networks
(Journal article; Peer reviewed, 2022)The prosperity of urban life is dependent on its infrastructure. Urban underground infrastructure components (assets) are aging and need regular monitoring, maintenance and rehabilitation. These assets are often placed ... -
Samvirkepåstøp på hulldekker
(Master thesis, 2024)Samvirkepåstøp på hulldekker har ikke vært spesielt utbredt tidligere. Dette kommer blant annet av manglende beregningsgrunnlag og at det er en del usikkerhetsparametere i forbindelse med utførelsen. Det vil ikke være ... -
On the use of multi-objective optimization for multi-site calibration of extensive green roofs
(Journal article; Peer reviewed, 2022)Conceptual hydrological models are practical tools for estimating the performance of green roofs. Such models require calibration to obtain parameter values, which limits their use when measured data are not available. One ... -
Precision calculation of the entrance length for laminar flow of Bingham fluid between parallel plates with yield number from 0 to 1000
(Journal article; Peer reviewed, 2024)An estimate of the entrance length for a Bingham fluid flowing between parallel plates is needed in engineering applications. The dimensionless entrance length is a function of yield number. The primary objective of this ... -
Modeling of Subsea CO2 Transportation and Injection Pipe Networks, The Case of Snøhvit
(Master thesis, 2024)Gassinjeksjon har vært brukt i olje- og gassindustrien i mange år og har bidratt til å utvinne millioner av fat som ikke kunne blitt utvunnet med den primære drivmekanismen. Distribusjonsnettverk for gassinjeksjon blir ... -
A numerical study on the effects of DP steel microstructure on the yield locus and the stress–strain response under strain path change
(Journal article; Peer reviewed, 2023)The mechanical response of dual phase (DP) steel exhibits a complex dependence on the microstructure. The chemical composition and microstructure characteristics of the phases have significant effects on the contrast between ... -
Effect of heat treatment and defects on the tensile behavior of a hot work tool steel manufactured by laser powder bed fusion
(Journal article; Peer reviewed, 2023)Microstructure and tensile properties of a hot work tool steel manufactured via laser powder bed fusion (LPBF) were investigated. Specimens were built under two different orientations and subjected to two quenching and ... -
Comparative Study of Hydrogen Reduction of Bauxite Residue-Calcium Sintered and Self-Hardened Pellets Followed by Magnetic Separation for Iron Recovery
(Journal article; Peer reviewed, 2023)To minimize the carbon footprint in the industrial valourization of bauxite residue, hydrogen was used as a reducing agent. The current study experimentally investigated hydrogen reduction of bauxite residue-CaO sintered ... -
A review on hydrogen embrittlement and risk-based inspection of hydrogen technologies
(Journal article; Peer reviewed, 2023)Hydrogen could gradually replace fossil fuels, mitigating the human impact on the environment. However, equipment exposed to hydrogen is subjected to damaging effects due to H2 absorption and permeation through metals. ... -
Investigating electrochemical charging conditions equivalent to hydrogen gas exposure of X65 pipeline steel
(Journal article; Peer reviewed, 2023)In this study, we systematically investigate electrochemical hydrogen charging conditions equivalent to hydrogen gas pressures relevant for hydrogen transportation in X65 pipeline steel. By performing hydrogen gas permeation, ... -
Multi-material Joining of an Aluminum Alloy to Copper, Steel, and Titanium by Hybrid Metal Extrusion & Bonding
(Journal article; Peer reviewed, 2023)Hybrid metal extrusion & bonding (HYB) is a solid-state welding method where an aluminum (Al) filler wire is continuously extruded into the weld groove between the metal parts to be joined by the use of a rotating steel ... -
Energy efficiency of oil and gas production plant operations
(Journal article; Peer reviewed, 2023)The exploitation of subsurface resources is an energy-intensive activity leading to substantial emissions. The main energy consumer for hydrocarbon production is gas compression and pumping. In this article, we investigate ... -
