On the Effect of Boundary Conditions on the Flow around a Cylinder in a Channel
(Chapter, 2015)In this paper, the incompressible external flow around an offshore drilling riser with fairings at Reynolds number 5000 is used to study the effects of varying boundary conditions in numerical simulations. We use a direct ... -
On the effect of calcium lignosulfonate on the rheology and setting time of cement paste
(Journal article; Peer reviewed, 2017)The effect of softwood calcium lignosulfonate, LSs, on the rheology and setting time of cement paste has been investigated. Two Portland cements with different surface area and C3A content were used. The lignosulfonate was ... -
On the effect of changing handgrip position on joint specific power and cycling kinematics in recreational and professional cyclists
(Peer reviewed; Journal article, 2020)Introduction In cycling, the utilization of the drops position (i.e. the lowest handlebar position relative to the ground) allows for reduced frontal area, likely improved aerodynamics and thus performance compared to the ... -
On the Effect of CO2 on Seismic and Ultrasonic Properties: A Novel Shale Experiment
(Peer reviewed; Journal article, 2021)Carbon capture and storage (CCS) by geological sequestration comprises a permeable formation (reservoir) for CO2 storage topped by an impermeable formation (caprock). Time-lapse (4D) seismic is used to map CO2 movement in ... -
On the effect of pilot holes on the mechanical behaviour of flow-drill screw joints. Experimental tests and mesoscale numerical simulations
(Peer reviewed; Journal article, 2021)This research work investigated in detail the mechanical performance of a flow-drill screw connection of two aluminium plates with and without pilot holes. An extensive experimental campaign involving material and joint ... -
On the effect of plastic anisotropy, strength and work hardening on the tensile ductility of aluminium alloys
(Journal article; Peer reviewed, 2019)The influence of plastic anisotropy, yield strength and work hardening on ductile failure is studied by nonlinear finite element simulations and strain localization analyses of tensile tests in different material orientations. ... -
On the effect of positional encodings in Transformer models for time series forecasting
(Master thesis, 2021)Denne oppgaven undersøker effekten posisjons-koding (positional encoding) har på prediksjon av tidsrekker med Transformer modeller. Prediksjon av tidsrekker er et viktig problem med mange bruksområder. Nøyaktige prediksjoner ... -
On the effect of rounding on hypothesis testing when sample size is large
(Peer reviewed; Journal article, 2022)It is well known that sample moments are more sensitive and less robust than order statistics for robustness with respect to outliers. In this article, we show that the situation is exactly the opposite for robustness with ... -
On the effect of the approach velocity on the coalescence of fluid particles
(Journal article; Peer reviewed, 2019)The effect of the constant relative approach velocity of two Newtonian fluid particles on their coalescence is investigated via a film drainage model. The interfaces are deformable and allowed to have any degree of mobility. ... -
On the effect of the node and building orientation on the fatigue behavior of L-PBF Ti6Al4V lattice structure sub-unital elements
(Peer reviewed; Journal article, 2021)Despite the great potential of additively manufactured (AM) metallic lattice materials, a comprehensive understanding of their mechanical behavior, particularly fatigue, has yet to be achieved. The role of the sub-unital ... -
On the effect of water-induced degradation of thin-film piezoelectric microelectromechanical systems
(Peer reviewed; Journal article, 2021)Lifetime and reliability in realistic operating conditions are important parameters for the application of thin-film piezoelectric microelectromechanical systems (piezoMEMS) based on lead zirconate titanate (PZT). Humidity ... -
On the effect of wicking on the droplet cooling
(Master thesis, 2018)Several thermal management applications operating at low temperatures require the liquid to spread as much as fast as possible in order to improve the cooling performance. Due to the recent progresses in micro/nano technology, ... -
On the Efficiency of Data Communication for the Ultramonit Corrosion Monitoring System
(Master thesis, 2006)Ultramonit is a system under development for permanent installation on critical parts of the subsea oil- and gas pipelines in order to monitor the corrosion continuously by using ultrasound. The communication link which ... -

On the electrocatalytic symbiotic synergism between Pt, Ni and Al in plasma vapour deposited Pt<inf>x</inf>Ni<inf>y</inf>Al<inf>z</inf> thin metal films for water electrolysis
(Journal article; Peer reviewed, 2021)This work highlights the fact that the activity of an already active metal/surface, i.e. Ni, can be increased even further by combining it with metals/surfaces that exhibit low activity, i.e. Pt and Al, when used on their ... -
On the electrokinetic characterization of charged polymeric membranes by transversal streaming potential
(Peer reviewed; Journal article, 2021)The effect of a transmembrane pressure on the electrokinetic properties of different polymeric charged membranes is analysed. Electrokinetic characterization can involve the application of increasing or decreasing pressure ... -
On the Enabling Effect of Simulations for Decision-Making Support for Supply Chain Resilience A Preliminary Investigation
