A flexible autonomous robotic observatory infrastructure for bentho-pelagic monitoring
(Peer reviewed; Journal article, 2020)This paper presents the technological developments and the policy contexts for the project “Autonomous Robotic Sea-Floor Infrastructure for Bentho-Pelagic Monitoring” (ARIM). The development is based on the national ... -
A laboratory scale approach to wettability restoration in chalk core samples
(Peer reviewed; Journal article, 2019)Wettability in chalk has been studied comprehensively to understand fluid flow mechanisms impacting coreflooding experiments. Wettability becomes paramount in understanding the parameters influencing chalk-fluid interactions. ... -
A new framework for assessing subject-specific whole brain circulation and perfusion using MRI-based measurements and a multi-scale continuous flow model
(Peer reviewed; Journal article, 2019)A large variety of severe medical conditions involve alterations in microvascular circulation. Hence, measurements or simulation of circulation and perfusion has considerable clinical value and can be used for diagnostics, ... -
A pore-scale model for permeable biofilm: Numerical simulations and laboratory experiments
(Peer reviewed; Journal article, 2018)In this paper, we derive a pore-scale model for permeable biofilm formation in a two-dimensional pore. The pore is divided into two phases: water and biofilm. The biofilm is assumed to consist of four components: water, ... -
Accounting for model errors of rock physics models in 4D seismic history matching problems: A perspective of machine learning
(Journal article; Peer reviewed, 2021)Model errors are ubiquitous in practical history matching problems. A common approach in the literature to accounting for model errors is to treat them as random variables following certain presumed distributions. While ... -
Acoustic characterization of an artificial CO2 seep using split-beam echo sounders
(Journal article; Peer reviewed, 2019)Geological carbon storage (GCS) has emerged as a promising method for reducing greenhouse gas emissions and achieving international climate goals. Currently, sub-seafloor GCS sites sequester about 1.8 MtCO2/yr. Additional ... -
Acoustic emission based condition monitoring study of piston rod seals by varying speed and pressure parameters
(Peer reviewed; Journal article, 2020)Seal wear is one of the primitive causes of failure in hydraulic cylinders. Regular visual inspection of seals without affecting the productivity is difficult as the seals are placed internally in the hydraulic cylinder ... -
Acoustic Emission-Based Condition Monitoring and Remaining Useful Life Prediction of Hydraulic Cylinder Rod Seals
(Peer reviewed; Journal article, 2021)The foremost reason for unscheduled maintenance of hydraulic cylinders in industry is caused by wear of the hydraulic seals. Therefore, condition monitoring and subsequent estimation of remaining useful life (RUL) methods ... -

Adaptive Elements in Internet-Delivered Psychological Treatment Systems: Systematic Review
(Journal article; Peer reviewed, 2020)Background: Internet-delivered psychological treatments (IDPTs) are built on evidence-based psychological treatment models, such as cognitive behavioral therapy, and are adjusted for internet use. The use of internet ... -
Adaptive Systems for Internet-Delivered Psychological Treatments
(Peer reviewed; Journal article, 2020)Internet-Delivered Psychological Treatments (IDPT) are based on evidence-based psychological treatment models adjusted for interaction through the Internet. The use of Internet technologies has the potential to increase ... -
Advances in InSAR Analysis of Permafrost Terrain
(Peer reviewed; Journal article, 2024)Differential interferometric synthetic aperture radar (InSAR) is a remote sensing technique for measuring surface displacements with precision down to millimeters, most commonly from satellites. In permafrost landscapes, ... -
Advancing Deep Learning to Improve Upstream Petroleum Monitoring
(Peer reviewed; Journal article, 2019)Data analytics is rapidly growing field in both academia and industry dealing with processing and interpreting large and complex data sets. It has got already many successful applications via advancing machine (ML) and ... -
An agenda for the future of Arctic snow research: the view from Svalbard
(Journal article; Peer reviewed, 2023)The Arctic region is warming at over twice the mean rate of the Northern Hemisphere and nearly four times faster than the globe since 1979. The local rate of warming is even higher in the European archipelago of Svalbard. ... -
An Upscaled Model for Permeable Biofilm in a Thin Channel and Tube
(Peer reviewed; Journal article, 2020)In this paper, we derive upscaled equations for modeling biofilm growth in porous media. The resulting macroscale mathematical models consider permeable multi-species biofilm including water flow, transport, detachment and ... -
Analyse av Sentinel-1 data til deteksjon og varsling av kvikkleireskredet på Gjerdrum
(Research report, 2022)Denne rapporten gir en oversikt over arbeidet gjort i prosjektet «Analyse av Sentinel-1 data i forkant av kvikkleireskredet på Gjerdrum». Prosjektets formål var å undersøke om backscatter data fra Sentinel-1 satellittene ... -
An analysis of winter rain-on-snow climatology in Svalbard
(Peer reviewed; Journal article, 2024)Rain-on-snow (ROS) events are becoming an increasingly common feature of the wintertime climate Svalbard in the High Arctic due to a warming climate. Changes in the frequency, intensity, and spatial distribution of wintertime ... -
An analytical 1D model for computing low-frequency electromagnetic fields in material layers: Application to metallurgical furnaces
(Journal article; Peer reviewed, 2025)An analytical one-dimensional model for the distribution of electric fields within multiple material layers is developed and analyzed. The model originates from the study of large three-phase electric smelting furnaces for ... -
Arctic sea ice mass balance in a new coupled ice–ocean model using a brittle rheology framework
