Geocellular rendering of cave surveys in paleokarst reservoir models
(Peer reviewed; Journal article, 2020)Infilled and collapsed cave systems are an important component of many paleokarst reservoirs. Incorporating these features into industrial reservoir models commonly relies on geostatistical modelling methods that often ... -
Geologi, jordsmonn og botaniske undersøkelser på Lisle Lyngøy (delrapport 1)
(Research report, 2023)Lisle Lyngøya ligger i nordspissen av Øygarden kommune, som geologisk sett er en del av den norske strandflaten. Strandflaten er karakterisert av nederodert lavland, og strekker seg langs hele norskekysten med unntak av ... -
Great expectations: Migrant parents and parent-school cooperation in Norway
(Peer reviewed; Journal article, 2020)One long-standing characteristic of schools in Norway is inclusive education as a primary goal. The last years, the Norwegian government has emphasised increased parent-school cooperation as a way to limit risks, i.e. of ... -
Guideline Societal Embeddedness Assessment
(DigiMon ACT2 (NORCE);D3.1, Research report, 2020)The Societal Embeddedness Level (SEL) is a novel methodology which provides insight in the societal requirements for a technological innovation to be deployed. It contributes to the realization of technological innovations ... -
Harmony Phase 0/A
(Research report, 2019)This technical note provides some general considerations on the geophysical requirements of the Harmony L2 Ocean products and their implications to the mission requirements. Section 2 gives an overview of the geophysical ... -
Health Indicator for Low-speed Axial Bearings using Variational Autoencoders
(Peer reviewed; Journal article, 2020)This paper proposes a method for calculating a health indicator (HI) for low-speed axial rolling element bearing (REB) health assessment by utilizing the latent representation obtained by variational inference using ... -
Helicopter-borne RGB orthomosaics and photogrammetric digital elevation models from the MOSAiC Expedition
(Peer reviewed; Journal article, 2023)The Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition took place between October 2019 and September 2020 giving the rare opportunity to monitor sea-ice properties over a full annual ... -
Heterogeneous Multi-Robot Collaboration for Coverage Path Planning in Partially Known Dynamic Environments
(Peer reviewed; Journal article, 2024)This research presents a cooperation strategy for a heterogeneous group of robots that comprises two Unmanned Aerial Vehicles (UAVs) and one Unmanned Ground Vehicles (UGVs) to perform tasks in dynamic scenarios. This paper ... -
Hierarchical Representation Learning in Graph Neural Networks with Node Decimation Pooling
(Peer reviewed; Journal article, 2020)Abstract—In graph neural networks (GNNs), pooling operators compute local summaries of input graphs to capture their global properties, and they are fundamental for building deep GNNs that learn hierarchical representations. ... -
Homotopy scattering series for seismic forward modelling with variable density and velocity
(Peer reviewed; Journal article, 2021)We have derived a convergent scattering series solution for the frequency-domain wave equation in acoustic media with variable density and velocity. The convergent scattering series solution is based on the homotopy analysis ... -
Hybrid Iterative Ensemble Smoother for History Matching of Hierarchical Models
(Peer reviewed; Journal article, 2022)The choice of a prior model can have a large impact on the ability to assimilate data. In standard applications of ensemble-based data assimilation, all realizations in the initial ensemble are generated from the same ... -
HYDROGEN POWERED VESSELS AT SEA:FUEL CELL & BATTERY UPSCALING
(Chapter, 2022)There is today a strong effort in developing fuel cell / battery systems for ship propulsion to achieve zero-emission maritime transport, in accordance with UN sustainability goals and the Fit For 55 plan to achieve the ... -
Iceberg Detection With RADARSAT-2 Quad-Polarimetric C-Band SAR in Kongsfjorden, Svalbard-Comparison With a Ground-Based Radar
(Peer reviewed; Journal article, 2024)Satellite monitoring of icebergs in the Arctic region is paramount for the safety of shipping and maritime activities. The potential of polarimetric synthetic aperture radar data in enhancing detection capabilities of ... -

Impact of time-dependent wettability alteration on the dynamics of capillary pressure
(Peer reviewed; Journal article, 2020)Wettability is a pore-scale property that has an important impact on capillarity, residual trapping, and hysteresis in porous media systems. In many applications, the wettability of the rock surface is assumed to be constant ... -
Implicit linearization scheme for nonstandard two-phase flow in porous media
(Peer reviewed; Journal article, 2020)In this article, we consider a nonlocal (in time) two‐phase flow model. The nonlocality is introduced through the wettability alteration induced dynamic capillary pressure function. We present a monotone fixed‐point iterative ... -
Importance Weighting in Hybrid Iterative Ensemble Smoothers for Data Assimilation
(Peer reviewed; Journal article, 2024)Because it is generally impossible to completely characterize the uncertainty in com- plex model variables after assimilation of data, it is common to approximate the uncertainty by sampling from approximations of the ... -
