Prediction of extreme cargo ship panel stresses by using deconvolution
(Peer reviewed; Journal article, 2022)Extreme value predictions typically originate from certain functional classes of statistical distributions to fit the data and are subsequently extrapolated. This paper describes an alternative method for extrapolation ... -
Hole cleaning and wet-granular rheology of rock cutting beds: Impact of drilling fluid composition
(Peer reviewed; Journal article, 2022)Cuttings-beds formation is an issue that must be considered during all wellbore drilling operations. This problem increases at highly deviated or horizontal wells, where cuttings removal efficiency becomes one of the most ... -
Numerical Optimisation of a Classical Stochastic System for Targeted Energy Transfer
(Peer reviewed; Journal article, 2022)The paper studies stochastic dynamics of a two-degree-of-freedom system, where a primary linear system is connected to a nonlinear energy sink with cubic stiffness nonlinearity and viscous damping. While the primary mass ... -
Dynamic design and analysis of subsea CO2 discharging flowline for cargo submarines used for CCS in low-carbon and renewable energy value chains
(Peer reviewed; Journal article, 2022)Developing offshore low carbon and renewable energy value chains to realize a net-zero energy future requires combining offshore renewable energy and carbon capture storage (CCS) solutions. The subsea shuttle tanker (SST) ... -
Effective recovery of microalgal biomass using various types of emulsion polymers
(Peer reviewed; Journal article, 2022)Microalgae biomass has been considered as one of the potential feedstocks in biofuel production. Yet, biomass harvesting poses a challenge to the overall production cost due to its low cell density. Flocculation has been ... -
Invasion of CaCO3 particles and polymers into porous formations in presence of fibres
(Peer reviewed; Journal article, 2022)Formation damage can occur through migration of drilling fluid particles and polymers into porous formations. A methodology for assessing formation damage was applied to measure invasion of CaCO3 and polymers into porous ... -
Hvordan er påliteligheten til perimetersikringen rundt Industriområdet?
(Studentoppgave/UIS-TN-ISØP/2022;, Master thesis, 2022-06)Hvordan er norske industriområder sikret mot uønsket adgang gjennom perimetersikringer? Er norske industriområder tilstrekkelig sikret mot uønsket inntrenging og har man tilstrekkelig fokus på security, sikring mot villede ... -
Potential for improving the efficiency of terrigenous oil deposits waterflooding with the use of low salinity technology at fields of the Tatarstan Republic
(Peer reviewed; Journal article, 2022) -
UiS Subsea-Freight Glider: A large buoyancy-driven autonomous cargo glider
(Peer reviewed; Journal article, 2022)This study presents the baseline design for the autonomous subsea vehicle capable of traveling at a lower speed of 1 m/s with an operating range of 400 km. Owing to UiS subsea-freight glider’s (USFG) exceedingly economical ... -
Towards an understanding of learning within the Norwegian fire and rescue services – focusing on tunnel fire safety
(Peer reviewed; Journal article, 2022)Purpose The purpose of this paper is to study how learning within the fire and rescue services may be conceptualized, with special attention paid to tunnel fire safety. Previous studies have developed a model to understand ... -
Optimisation of Thimble simulations and quantum dynamics of multiple fields in real time
(Peer reviewed; Journal article, 2022)We apply the Generalised Thimble approach to the computation of exact path integrals and correlators in real-time quantum field theory. We first investigate the details of the numerical implementation and ways of optimizing ... -
A novel multi regional reliability method for Covid-19 death forecast
(Peer reviewed; Journal article, 2022)Novel coronavirus disease is spread worldwide with considerable morbidity and mortality and presents an enormous burden on worldwide public health. The present study describes a novel bio-system reliability approach, ... -
Optimum directional well path design considering collapse and fracture pressures
(Peer reviewed; Journal article, 2022)Well path optimisation is often done based on the wellbore stability where the production related concerns are ignored. In fact, many of the studies carried out in the past have not included hydraulic fractures into their ... -
Loss of LEUCINE CARBOXYL METHYLTRANSFERASE 1 interferes with metal homeostasis in Arabidopsis and enhances susceptibility to environmental stresses
(Peer reviewed; Journal article, 2022)The biochemical function of LEUCINE CARBOXYL METHYLTRANSFERASE 1 (LCMT1) is to transfer a methyl group from the methyl donor S-adenosylmethionine (SAM) to the catalytic subunits of PROTEIN PHOSPHATASE 2A (PP2Ac), PP4 and ... -
A study of inhomogeneous massless scalar gauge fields in cosmology
(Peer reviewed; Journal article, 2022)Why is the Universe so homogeneous and isotropic? We summarize a general study of a γ-law perfect fluid alongside an inhomogeneous, massless scalar gauge field (with homogeneous gradient) in anisotropic spaces with General ... -
Bonding Mechanism of Zonal Isolation Materials to Clean and Rusted Casing
(Peer reviewed; Journal article, 2022)In oil and gas and geothermal well construction, a cementitious material is pumped in the wellbore to provide zonal isolation and support the casing during the life cycle of the well. Thus, the cementitious barrier materials ... -
