Calculating expected effects of treatment effectivity and river flow rates on the contribution of WWTP effluent to the ARG load of a receiving river
(Peer reviewed; Journal article, 2021)Concentrations of genetic markers for antibiotic resistance genes (ARGs) were measured in the effluents of three Norwegian wastewater treatment plants (WWTPs) and in a receiving river upstream and downstream of the discharge ... -
Sailing status recognition to enhance safety awareness and path routing for a commuter ferry
(Peer reviewed; Journal article, 2021)This paper suggests a framework about how log data are used to develop a classifier to recognise the sailing status of a commuter ferry, which, in turn, serves as a tool of safety awareness. Several sailing scenarios are ... -
Ombruk av byggematerialer og - produkter i et bærekraftperspektiv - Vurdering av miljøeffekt og kartlegging av potensialet for en oppskalering av ombruksmarkedet
(Master thesis, 2020)Sammendrag Klimaendringer og overforbruk av jordas begrensede ressurser er en reell trussel, og det er nødvendig å gjøre store endringer i dagens samfunn for å unngå irreversible konsekvenser. I tråd med FNs arbeid for ... -

High-Fidelity Representation of Three-Hour Offshore Short-Crested Wave Field in the Fully Nonlinear Potential Flow Model REEF3D::FNPF
(Chapter, 2020)Stochastic wave properties are crucial for the design of offshore structures. Short-crested seas are commonly seen at the sites of offshore structures, especially during storm events. A long time duration is required in ... -
An Improved Depth-Averaged Non-Hydrostatic Shallow Water Model with Quadratic Pressure Approximation
(Peer reviewed; Journal article, 2020)Phase‐resolved information is necessary for many coastal wave problems, for example, for the wave conditions in the vicinity of harbor structures. Two‐dimensional (2D) depth‐averaging shallow water models are commonly used ... -
Numerical simulation and analysis of phase focused breaking and non-breaking wave impact on fixed offshore platform deck
(Peer reviewed; Journal article, 2020)Extreme wave impact due to tsunamis and storm surge create large wave heights that cause destruction to coastal and offshore structures. Focused waves have been used to represent such extreme waves, and in the present ... -
Representation of Breaking Wave Kinematics in the Fully Nonlinear Potential Flow Model REEF3D::FNPF
(Chapter, 2020)Robust simulations over three-hours are essential to represent a stationary sea state and derive wave statistics and structural response of marine structures in a reliable manner. This means that the numerical model used ... -
REEF3D::FNPF – A Flexible Fully Nonlinear Potential Flow Solver
(Peer reviewed; Journal article, 2020)In situations where the calculation of ocean wave propagation and impact on structures are required, fast numerical solvers are desired in order to find relevant wave events. Computational fluid dynamics (CFD)-based numerical ... -
Review of the relationship between aggregates geology and Los Angeles and micro-Deval tests
(Peer reviewed; Journal article, 2021)Rock aggregates constitute the enormous volume of inert construction material used around the globe. The petrologic description as igneous, sedimentary, and metamorphic types establishes the intrinsic formation pattern of ... -
Surpassing the Limits to Human Cognition? On the Level of Detail in the Norwegian Building Design Guide
(Journal article, 2021)The SINTEF Building Research Design Guides are a series of Norwegian building technical recommendations. The design guides are highly reputed and widely used in the Norwegian construction sector, serving as a link between ... -
3D numerical modelling of scour around a jacket structure with dynamic free surface capturing
(Peer reviewed; Journal article, 2020)This paper presents a numerical investigation of local scour with dynamic free surface capturing around a jacket structure. The hydrodynamics and resulting scour are calculated using the open-source CFD model REEF3D. The ... -
Flushing of Stagnant Premise Water Systems after the COVID-19 Shutdown Can Reduce Infection Risk by Legionella and Mycobacterium spp.
(Peer reviewed; Journal article, 2020)There is concern about potential exposure to opportunistic pathogens when reopening buildings closed due to the COVID-19 pandemic. In this study, water samples were collected before, during, and after flushing showers in ... -
Numerical Simulation of Wave Interaction with Submerged Porous Structures
(Peer reviewed; Journal article, 2020)The study of wave interaction with porous structures is essential as coastal structures are often porous in nature because of their prominent energy dissipation characteristics. The present work is focused on the numerical ... -
A Lagrangian approach for the coupled simulation of fixed net structures in a Eulerian fluid model
(Peer reviewed; Journal article, 2020)A Lagrangian approach for the coupled numerical simulation of fixed net structures and fluid flow is derived. The model is based on solving the Reynolds-averaged Navier–Stokes equations in a Eulerian fluid domain. The ... -
Modeling porous coastal structures using a level set method based VRANS-solver on staggered grids
(Peer reviewed; Journal article, 2020)Several engineering problems in the field of coastal and offshore engineering involve flow interaction with porous structures such as breakwaters, sediment screens, and scour protection devices. In this paper, the interaction ... -
Elucidating the role of tetraethylammonium in the silicate condensation reaction from Ab initio molecular dynamics simulations
(Journal article; Peer reviewed, 2020)The understanding of the formation of silicate oligomers in the initial stage of zeolite synthesis is important. The use of organic structure-directing agents (OSDAs) is known to be a key factor in the formation of different ... -
Fuel characterization and thermal degradation kinetics of biomass from phytoremediation plants
(Journal article; Peer reviewed, 2020)Biomass obtained from phytoremediation energy crops Miscanthus x giganteus and Sida hermaphrodita planted on different soils contaminated with heavy metals was thermogravimetrically studied and kinetically analyzed, assuming ... -
Hydropower‐driven thermal changes, biological responses and mitigating measures in northern river systems
(Peer reviewed; Journal article, 2021)Water temperatures control life histories and diversity of aquatic species. Hydropower regulation, particularly in high head systems, alters natural water temperature regimes, which may have profound and long-term impacts ... -
