Seasonal InSAR Displacements Documenting the Active Layer Freeze and Thaw Progression in Central-Western Spitsbergen, Svalbard
(Peer reviewed; Journal article, 2021)In permafrost areas, the active layer undergoes seasonal frost heave and thaw subsidence caused by ice formation and melting. The amplitude and timing of the ground displacement cycles depend on the climatic and ground ... -
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 ... -
A set of web-based public decision support tools for integrated planning and management in aquaculture
(Journal article; Peer reviewed, 2022)We developed a set of web-based tools to meet the demand for spatial planning and help to determine the available space suitable for marine aquaculture activity. These tools were derived from AkvaVis concept, which was ... -
Sex-based differences in sub-technique selection during an international classical cross-country skiing competition
(Peer reviewed; Journal article, 2020)The purpose of this study was to compare speed, sub-technique selection and temporal patterns between world-class male and female cross-country (XC) skiers and to examine the combined associations of sex and speed on ... -
Short-Term Load Forecasting with Missing Data using Dilated Recurrent Attention Networks
(Peer reviewed; Journal article, 2020)Forecasting the dynamics of time-varying systems is essential to maintaining the sustainability of the systems. Recent studies have discovered that Recurrent Neural Networks(RNN) applied in the forecasting tasks outperform ... -
Simulating offshore hydrogen production via PEM electrolysis using real power production data from a 2.3 MW floating offshore wind turbine
(Peer reviewed; Journal article, 2023)This work presents simulation results from a system where offshore wind power is used to produce hydrogen via electrolysis. Real-world data from a 2.3 MW floating offshore wind turbine and electricity price data from Nord ... -
Simulation-driven Deep Classification of Bearing Faults from Raw Vibration Data
(Peer reviewed; Journal article, 2019)The industry is moving towards maintenance strategies that consider component health, which require extensive collection and analysis of data. Condition monitoring methods that require manual feature extraction and analysis, ... -
SIOS’s Earth Observation (EO), Remote Sensing (RS), and operational activities in response to COVID-19
(Journal article; Peer reviewed, 2021)Svalbard Integrated Arctic Earth Observing System (SIOS) is an international partnership of research institutions studying the environment and climate in and around Svalbard. SIOS is developing an efficient observing system, ... -
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 ... -
