Skin and Proximity Effects in Electrodes and Furnace Shells
(Peer reviewed; Journal article, 2019)A review of two-dimensional (2D) analytical models of skin and proximity effects in large industrial furnaces with three electrodes arranged in an equilateral triangle is given. The models cover three different cases: one ... -
Spectral Clustering with Graph Neural Networks for Graph Pooling
(Peer reviewed; Journal article, 2020)Spectral clustering (SC) is a popular clustering technique to find strongly connected communities on a graph. SC can be used in Graph Neural Networks (GNNs) to implement pooling operations that aggregate nodes belonging ... -
Spread Spectrum Modulation with Grassmannian Constellations for Mobile Multiple Access Underwater Acoustic Channels
(Journal article; Peer reviewed, 2022)The objective of this study is to evaluate Grassmannian constellations combined with a spread spectrum multiple access scheme for underwater acoustic mobile multiple access communication systems. These communication systems ... -
Status of Foam as a Liquid Blocking Agent in Porous Media: A Review
(Journal article; Peer reviewed, 2023)Abstract This article summarizes the state-of-the-art knowledge gained from field observations and laboratory studies regarding foam as a liquid controlling agent in porous media. Being the least explored property of foam, ... -
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 ... -
A Stochastic Covariance Shrinkage Approach in Ensemble Transform Kalman Filtering
(Peer reviewed; Journal article, 2023)The Ensemble Kalman Filters (EnKF) employ a Monte-Carlo approach to represent covariance information, and are affected by sampling errors in operational settings where the number of model realizations is much smaller than ... -
Surface Complexation Modelling of Wettability Alteration during Carbonated Water Flooding
(Peer reviewed; Journal article, 2022)CO2 capture and utilization is an effective tool in reducing greenhouse gas emissions and hence, combating global warming. In the present study, surface complexation modeling (SCM) with the geochemistry solver, PHREEQ-C, ... -
A Survey on Distributed Fibre Optic Sensor Data Modelling Techniques and Machine Learning Algorithms for Multiphase Fluid Flow Estimation
(Peer reviewed; Journal article, 2021)Real-time monitoring of multiphase fluid flows with distributed fibre optic sensing has the potential to play a major role in industrial flow measurement applications. One such application is the optimization of hydrocarbon ... -
Tectonic-magmatic-hydrothermal interactions in a hot dry rock geothermal system: The role of the transfer and normal faults in the Acoculco caldera (Mexico)
(Peer reviewed; Journal article, 2023)In the Acoculco caldera (hot dry rock system) two geothermal boreholes were planned to intersect fracture systems in the carbonate basement. Even though the caldera is located in an area of active deformation with high ... -
The association of PTSD symptom severity with amygdala nuclei volumes in traumatized youths
(Peer reviewed; Journal article, 2020)The amygdala is a core component in neurobiological models of stress and stress-related pathologies, including post-traumatic stress disorder (PTSD). While numerous studies have reported increased amygdala activity following ... -
The dissolution of a miscible drop rising or falling in another liquid at low Reynolds number
(Peer reviewed; Journal article, 2023)“A basic and basically unsolved problem in fluid dynamics is to determine the evolution of rising bubbles and falling drops of one miscible liquid in another” [D. D. Joseph and Y. Y. Renardy, Fundamentals of Two-Fluid ... -
The generalization of Gulland’s method: How to estimate maturity ogives when juvenile data are missing while spawner demography is known
(Peer reviewed; Journal article, 2019)The proportions of mature individuals at age or length, collectively known as the maturity ogive, are a key population characteristic and serve as critical input to age-disaggregated stock assessments. John Gulland showed ... -
The Open Porous Media Flow Reservoir Simulator
(Peer reviewed; Journal article, 2020)The Open Porous Media (OPM) initiative is a community effort that encourages open innovation and reproducible research for simulation of porous media processes. OPM coordinates collaborative software development, maintains ... -
Tidal amplification and along‐strike process variability in a mixed‐energy paralic system prograding onto a low accommodation shelf, Edgeøya, Svalbard
(Journal article; Peer reviewed, 2020)The study describes the depositional development and sediment partitioning in a prograding paralic Triassic succession. The deposits are associated with the advance of large prism‐scale clinoforms across a shallower platform ... -
Treatment fidelity in a pragmatic clinical trial of music therapy for premature infants and their parents: the LongSTEP study
(Peer reviewed; Journal article, 2023)Background Treatment fidelity (TF) refers to methodological strategies used to monitor and enhance the reliability and validity of interventions. We evaluated TF in a pragmatic RCT of music therapy (MT) for premature ... -
Triaxial behavior of a stabilized and a highly porous oil well cement paste at different saturation and drainage conditions
(Peer reviewed; Journal article, 2022)Well cement is the most common barrier material in wells for geothermal and hydrocarbon production. As cements are exposed to hydrostatic loads and periods of deviatoric loading in wellbore environments, it is important ... -
Uncovering Contributing Factors to Interruptions in the Power Grid: An Arctic Case
(Peer reviewed; Journal article, 2022)Electric failures are a problem for customers and grid operators. Identifying causes and localizing the source of failures in the grid is critical. Here, we focus on a specific power grid in the Arctic region of Northern ... -
