Open-Source CFD in Marine Engineering
(Journal article, 2015)In the case of highly complex problems in the field of marine, coastal and ocean engineering involving the free surface, such as breaking wave kinematics or flow around slender structures, a detailed solution is required ... -
An open-source library for hydrodynamic simulation of marine structures
(Journal article; Peer reviewed, 2020) -
An Open-Source Python-Based Boundary-Element Method Code for the Three-Dimensional, Zero-Froude, Infinite-Depth, Water-Wave Diffraction-Radiation Problem
(Journal article; Peer reviewed, 2021)In this paper, a new open-source implementation of the lower-order, 3-D Boundary Element Method (BEM) of solution to the deep-water, zero Froude-number wave-body interaction problem is described. A validation case for ... -
An OpenFOAM solver for computing suspended particles in water currents
(Peer reviewed; Journal article, 2023)A new OpenFOAM solver has been developed for computing the spatial variation of particle concentrations in flowing water. The new solver was programmed in C ++ using OpenFOAM libraries, and the source code has been made ... -
Opening Bid Strategies in English Auctions
(Peer reviewed; Journal article, 2021)Existing residential homes in Norway are sold by English auctions. This provides an exclusive opportunity to examine opening bid strategies for high-valued objects. Using unique data from surveys and auction journals, we ... -
Opening dialogic spaces: Teachers’ metatalk on writing assessment
(Journal article; Peer reviewed, 2016)This article reports on a qualitative study of teachers’ collegial discussions on assessment of students’ texts, focusing on how they use assessment tools, argue and interact. The data consists of two sets of collaborative ... -
Openness and the welfare state: risk and income effects in protection without protectionism
(Peer reviewed; Journal article, 2023)Have recent trends in globalization changed the positive link between trade openness and social insurance? The consensus view – that voters want better social insurance against income loss the more open the economy – is ... -
Openness and trust in data-intensive science: the case of biocuration
(Peer reviewed; Journal article, 2020)Data-intensive science comes with increased risks concerning quality and reliability of data, and while trust in science has traditionally been framed as a matter of scientists being expected to adhere to certain technical ... -
Operability Analysis of Monopile Lowering Operation Using Different Numerical Approaches
(Journal article, 2016)Offshore installation operations require careful planning in the design phase to minimize associated risks. This study addresses numerical modeling and time-domain simulations of the lowering operation during installation ... -
Operability of Integrated Gasification Combined Cycle Power Plant with SEWGS Technology for Pre-combustion CO2 Capture
(Journal article; Peer reviewed, 2014)This paper investigates the performance of an integrated gasification combined cycle (IGCC) power plant incorporating a sorption enhanced water gas shift (SEWGS) process for pre-combustion CO2 capture at part-load conditions. ... -
Operability robustness index as seakeeping performance criterion for offshore vessels
(Peer reviewed; Journal article, 2020)The offshore industry operates increasingly large installations in exposed areas requiring high reliability and availability. Downtime of complex offshore systems leads to significant financial losses. Towards year-round ... -
An operadic approach to substitution in Lie-Butcher series
(Peer reviewed; Journal article, 2022)The paper follows an operadic approach to provide a bialgebraic description of substitution for Lie–Butcher series. We first show how the well-known bialgebraic description for substitution in Butcher’s B-series can be ... -
∞-Operads as Analytic Monads
(Peer reviewed; Journal article, 2022) -
∞-operads as symmetric monoidal ∞-categories
(Journal article; Peer reviewed, 2024) -
∞ -Operads via symmetric sequences
(Peer reviewed; Journal article, 2021)We construct a generalization of the Day convolution tensor product of presheaves that works for certain double \infty -categories. Using this construction, we obtain an \infty -categorical version of the well-known ... -
Operando detection of single nanoparticle activity dynamics inside a model pore catalyst material
(Peer reviewed; Journal article, 2020)Nanoconfinement in porous catalysts may induce reactant concentration gradients inside the pores due to local conversion. This leads to inefficient active material use since parts of the catalyst may be trapped in an ... -
Operando neutron imaging study of a commercial Li-ion battery at variable charge-discharge current densities
(Peer reviewed; Journal article, 2022)We report an operando neutron imaging study of a commercial ICR 10440 Li ion battery during charge and discharge. The cylindrical battery with a spiral configuration is composed of a multiphase layered oxide cathode and ... -
Operando studies of Mn oxide based electrocatalysts for the oxygen evolution reaction
(Peer reviewed; Journal article, 2023)Inspired by photosystem II (PS II), Mn oxide based electrocatalysts have been repeatedly investigated as catalysts for the electrochemical oxygen evolution reaction (OER), the anodic reaction in water electrolysis. However, ... -
Operating a Battery in a Hydropower-Dominated System to Balance Net Load Deviations
(Chapter, 2019)Decreasing costs of battery storage technologies make them a viable option for providing flexibility in power systems. In this paper, we study the operations of a battery in combination with cascaded hydropower in a system ... -
Operating cost reduction of DC microgrids under real-time pricing using adaptive differential evolution algorithm
