Microbial challenges in recirculating aquaculture systems (RAS) for Atlantic salmon (Salmo salar) smolt and post-smolt
(Doctoral thesis, 2021)Aquaculture is one of the fastest growing food producing sectors today. Norway is the world’s largest producer of farmed Atlantic salmon (Salmo salar), and the aquaculture industry is an important contributor to value ... -
Validation of a Swimming Direction Model for the Downstream Migration of Atlantic Salmon Smolts
(Peer reviewed; Journal article, 2021)Fish swimming performance is strongly influenced by flow hydrodynamics, but little is known about the relation between fine-scale fish movements and hydrodynamics based on in-situ investigations. In the presented study, ... -
The effect of rolling resistance on people’s willingness to cycle during wintertime
(Peer reviewed; Journal article, 2021)Harsh winters reduce utilitarian cycling in many cities. Using an online survey, we examined how increasing rolling resistance due to snow and ice affect people’s cycling willingness. The respondents (N = 1318) reported ... -
Numerical modelling of distinct ice lenses in frost heave
(Peer reviewed; Journal article, 2021)Frost heave happens when three conditions coincide: the temperature is below the normal freezing point of bulk water, the sub-cooled water is connected to a water reservoir, and the mechanical conditions of the soil allows ... -
Scale effects during cone penetration in spatially variable clays
(Journal article; Peer reviewed, 2020)Cone penetration testing (CPT) has become one of the most commonly adopted in situ tests for site investigations, due to its reliability and repeatability of the measurements and the potential for direct use in design. For ... -

Svalbard fjord environments with land-fast sea ice as arenas for climate research, monitoring, remote sensing validation, and dedicated process studies
(Peer reviewed; Journal article, 2020)During winter and spring, parts of Svalbard fjords are covered with land-fast sea ice. The extent of fast ice areas has decreased during the last two decades, and seasons with fjord ice cover have on average become shorter. ... -
Aerodynamic Investigation of Tucked Positions in Alpine Skiing
(Peer reviewed; Journal article, 2021)The purpose of this investigation was to examine the aerodynamics of tucked positions in competitive alpine skiing. To further our understanding of how a skier’s position affects the air flow and the resulting aerodynamic ... -
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 ...
