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, ... -
Fault Classification of Axial and Radial Roller Bearings Using Transfer Learning through a Pretrained Convolutional Neural Network
(Peer reviewed; Journal article, 2018)Detecting bearing faults is very important in preventing non-scheduled shutdowns, catastrophic failures, and production losses. Localized faults on bearings are normally detected based on characteristic frequencies associated ... -
Promoting exercise training and physical activity in daily life: a feasibility study of a virtual group intervention for behaviour change in COPD
(Peer reviewed; Journal article, 2018)Background Physical inactivity is associated with poor health outcomes in chronic obstructive pulmonary disease (COPD). It is therefore crucial for patients to have a physically active lifestyle. The aims of this feasibility ... -
Deep learning for graphs
(Chapter, 2018)Deep learning for graphs encompasses all those neural models endowed with multiple layers of computation operating on data represented as graphs. The most common building blocks of these models are graph encoding layers, ... -
Stick-slip and torsional friction factors in inclined wellbores
(Peer reviewed; Journal article, 2018)Stick slip is usually considered a phenomenon of bit-rock interaction, but is also often observed in the field with the bit off bottom. In this paper we present a distributed model of a drill string with an along-string ... -
Vocal Cord Function During Recurrent Laryngeal Nerve Injury Assessed by Accelerometry and EMG
(Peer reviewed; Journal article, 2019)Objective Gradual impairment of nerve conduction is expected to be tightly associated with simultaneous gradual loss of vocal cord contractility, related to the fact that injured axons are connected to a defined number ... -
Consistent ice and open water classification combining historical synthetic aperture radar satellite images from ERS-1/2, Envisat ASAR, RADARSAT-2 and Sentinel-1A/B
(Peer reviewed; Journal article, 2019)Synthetic Aperture Radar (SAR) satellite images are used to monitor Arctic sea ice, with systematic data records dating back to 1991. We propose a semi-supervised classification method that separates open water from sea ... -
Participatory Design of VR Scenarios for Exposure Therapy
(Chapter, 2019)Virtual reality (VR) applications for exposure therapy predominantly use computer-generated imagery to create controlled environments in which users can be exposed to their fears. Creating 3D animations, however, is demanding ... -
Petroleum, coal and research drilling onshore Svalbard: a historical perspective
(Peer reviewed; Journal article, 2019)The beginning of the Norwegian oil industry is often attributed to the first exploration drilling in the North Sea in 1966, the first discovery in 1967 and the discovery of the supergiant Ekofisk field in 1969. However, ... -
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 ... -
Scientific Assessment of TSCV - Retrieval from Stereo-Sar-Retrieval Algorithm
(Research report, 2019)In this technical note we provide a detailed description of ocean current retrieval algorithm to be applied in the end-toend performance simulator. The retrieval algorithm is based on the forward and retrieval models ... -
Sentinel-1 sar observations of peak wavelength and dominant wave direction in the marginal ice zone of the barents sea
(Peer reviewed; Journal article, 2019)Synthetic aperture radar (SAR) has proven to be a very important source of data in the Polar regions because it covers large areas continuously, independent of the weather and time of day. In this study, we make use of ... -
Snøskredaktivitet i Ramfjorden, Troms, 2014-2019
(Research report, 2019)Vi detekterte automatisk skred i Sentinel-1 radarsatellittdata i et definert område på ca. 9.5 km2 i Ramfjorden og Lavangsdalen, Tromsø kommune. Sentinel-1 data var tilgjengelig i perioden 2014-2019 og vi har lastet ned ... -
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, ... -
Microfluidic study of effects of flow velocity and nutrient concentration on biofilm accumulation and adhesive strength in the flowing and no-flowing microchannels
(Peer reviewed; Journal article, 2019)Biofilm accumulation in porous media can cause pore plugging and change many of the physical properties of porous media. Engineering bioplugging may have significant applications for many industrial processes, while improved ... -
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. ... -
Fault core thickness: Insights from siliciclastic and carbonate rocks
(Peer reviewed; Journal article, 2019)Fault core accommodates intense deformation in the form of slip surfaces and fault rocks such as fault gouge, cataclasite, breccia, lenses, shale smear, and diagenetic features. The complexity and variation in fault core ... -
LIME: Software for 3-D visualization, interpretation, and communication of virtual geoscience models
