    • Capacity and Limits of Multimodal Remote Sensing: Theoretical Aspects and Automatic Information Theory-Based Image Selection 

      Chlaily, Saloua; Mura, Mauro Della; Chanussot, Jocelyn; Jutten, Christian; Gamba, Paolo; Marinoni, Andrea (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-17)
      Although multimodal remote sensing data analysis can strongly improve the characterization of physical phenomena on Earth's surface, nonidealities and estimation imperfections between records and investigation models can limit its actual information extraction ability. In this article, we aim at predicting the maximum information extraction that can be reached when analyzing a given data set. By ...
    • A Novel Rayleigh Dynamical Model for Remote Sensing Data Interpretation 

      Bayer, Fábio M.; Bayer, Débora M.; Marinoni, Andrea; Gamba, Paolo (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-19)
      This article introduces the Rayleigh autoregressive moving average (RARMA) model, which is useful to interpret multiple different sets of remotely sensed data, from wind measurements to multitemporal synthetic aperture radar (SAR) sequences. The RARMA model is indeed suitable for continuous, asymmetric, and nonnegative signals observed over time. It describes the mean of Rayleigh-distributed ...
    • The Transformation of Extralegal Principles into Legal Principles by the International Court of Justice in The Hague: Illustrated by a Peaceful Delimitation of «the Promised Land» 

      Ørebech, Peter Th (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Social norms are mixtures of extralegal and legal principles. The International Court of Justice‟ in The Hague‟s (ICJ) adjudication subtracts normative structures from different sources, moral, ethical, religious etc. dogmas amplifying its case law. The failing Israel-Palestine reconciliation that results from “power asymmetries” and “supreme emergency exception”, illustrates how absence of concomitant ...
    • The networked handling of rush orders in customer services 

      Engelseth, Per; White, Brian E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Rush orders are characterised by time constraints and organisational priority. They are handled by the supplier with the aim of meeting customer requirements in as limited a timeframe as possible. Rather than focusing on rush orders as a deterministic planning problem, this paper takes an inter-organisational perspective that highlights the complex networked interactions between the supplier and the ...
    • Comparison of Machine Learning Methods for Predicting Quad-Polarimetric Parameters from Dual-Polarimetric SAR Data 

      Blix, Katalin; Espeseth, Martine; Eltoft, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-17)
      This paper addresses the problem of up-scaling full polarimetric (quad-pol) parameters from small quad-pol synthetic aperture radar (SAR) scenes to large dual-pol scenes, using a sophisticated Machine Learning (ML) method, namely the Gaussian Process Regression (GPR). The approach is to let the GPR model learn the relationships between the dual-pol input data and the quad-pol parameters on a quad-pol ...

      Gallego, Inmaculada; Font aulet, Xavier (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-05)
      This paper develops a methodology for the early detection of reactivation of tourist markets to help mitigate the effects of the COVID-19 crisis, using Skyscanner data on air passenger searches (>5,000 million) and picks (>600 million), for flights between November 2018 and December 2020, through ForwardKeys. For future travel during the May to September 2020 period, the desire to travel (based on ...
    • Carving the body at its joints: Does the way we speak about the body shape the way we think about it? 

      Devylder, Simon René Charles; Bracks, Christoph; Shimotori, Misuzu; Siahaan, Poppy (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-26)
      Looking at the way different linguistic communities speak about a universally shared domain of experience raises questions that are central to the language sciences. How can we compare meaning across languages? What is the interaction between language, thought, and perception? Does linguistic diversity entail linguistic relativism? The literature on the naming systems of the body across languages ...
    • Elevated Pain Threshold Levels in Elite Athletes 

      Pettersen, Susann Dahl (Master thesis; Mastergradsoppgave, 2019-04-26)
      The aim of this study was to examine the difference in pain perception between elite-athletes and non-athletes. The data previously obtained within this field of study is sparse and showing a significant variation in results. 52 healthy volunteers (18 females and 34 males) participated in an experimental study in which personality traits, fear of pain and grit (perseverance and passion for long-term ...
    • The fate of plastic in the ocean environment – a minireview 

      Wayman, Chloe; Niemann, Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-14)
      The presence of plastics in the marine environment poses a threat to ocean life and has received much scientific and public attention in recent years. Plastics were introduced to the market in the 1950s and since then, global production figures and ocean plastic littering have increased exponentially. Of the 359 million tonnes (Mt) produced in 2018, an estimated 14.5 Mt has entered the ocean. In ...
    • Deformation Behavior and Inferred Seismic Properties of Tonalitic Migmatites at the Time of Pre‐melting, Partial Melting, and Post‐Solidification 

      Shao, Yilun; Piazolo, Sandra; Liu, Yongjiang; Lee, Amicia; Jin, Wei; Li, Weimin; Liang, Chenyue; Wen, Quanbo (Journal article; Tidsskriftartikkel, 2021-01-21)
      As seismic data from the lower crust becomes more readily available, it is important to link seismic properties to the ongoing processes within lower crustal evolution. This includes high temperature, pre‐ and post‐migmatization solid state deformation as well as melt‐present deformation. We selected two tonalitic migmatites with variable former melt content (one metatexite and one diatexite) from ...
    • Evidence for influx of Atlantic water masses to the Labrador Sea during the Last Glacial Maximum 

      Seidenkrantz, Marit-Solveig; Kuijpers, Antoon; Sørensen, Steffen Aagaard; Lindgreen, Holger; Olsen, Jesper; Pearce, Christof (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-21)
      The Last Glacial Maximum (LGM, 23–19,000 year BP) designates a period of extensive glacial extent and very cold conditions on the Northern Hemisphere. The strength of ocean circulation during this period has been highly debated. Based on investigations of two marine sediment cores from the Davis Strait (1033 m water depth) and the northern Labrador Sea (2381 m), we demonstrate a significant influx ...
    • Insights into the REY inventory of seep carbonates from the Northern Norwegian margin using geochemical screening 

      Schier, Katharina; Himmler, Tobias; Lepland, Aivo; Kraemer, Dennis; Schönenberger, Jasmin; Bau, Michael (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-27)
      Rare earth element and yttrium (REY) systematics of authigenic seep carbonates can provide insights into the physico-chemical characteristics of seep systems and allow discrimination of carbonate precipitation under seawater- or porewater-dominated fluid regimes. However, care must be taken when interpreting their REY systematics, since seep carbonates comprise a mixture of detrital silicates and ...
    • Multiscale characterisation of chimneys/pipes: Fluid escape structures within sedimentary basins 

      Robinson, Adam H.; Callow, Ben; Böttner, Christoph; Yilo, Naima; Provenzano, Giuseppe; Falcon-Suarez, Ismael H; Marin-Moreno, Héctor; Lichtschlag, Anna; Bayrakci, Gaye; Gehrmann, Romina; Parkes, Lou; Roche, Ben; Saleem, Umer; Schramm, Bettina; Waage, Malin; Lavayssière, Aude; Li, Jianghui; Jedari-Eyvazi, Farid; Sahoo, Sourav; Deusner, Christian; Kossel, Elke; Minshull, Timothy A.; Berndt, Christian; Bull, Jonathan M.; Dean, Marcella; Chapman, Mark; Best, Angus I.; Bünz, Stefan; Chen, Baixin; Connelly, Douglas P.; Elger, Judith; Haeckel, Matthias; Henstock, Timothy J.; Karstens, Jens; Macdonald, Calum; Matter, Juerg M.; North, Laurence; Reinardy, Benedict (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-19)
      Evaluation of seismic reflection data has identified the presence of fluid escape structures cross-cutting overburden stratigraphy within sedimentary basins globally. Seismically-imaged chimneys/pipes are considered to be possible pathways for fluid flow, which may hydraulically connect deeper strata to the seabed. The properties of fluid migration pathways through the overburden must be constrained ...
    • Rethinking the role of solar energy under location specific constraints 

      Eikeland, Odin Foldvik; Apostoleris, Harry; Santos, Sergio; Ingebrigtsen, Karoline; Boström, Tobias; Chiesa, Matteo (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-22)
      In this manuscript we evaluate the potential of photovoltaic systems to meet some dedicated energy demand in specific geographic locations. Our approach is based on location-specific constraints rather than on pre-established, location-independent methodologies or assumptions. First, we propose that a thorough analysis of the socio-economic and technical possibilities of a location must act as the ...
    • A Possible Explanation of Interhemispheric Asymmetry of Equatorial Plasma Bubbles in Airglow Images 

      Hickey, Dustin A.; Sau, Sukanta; Narayanan, Viswanathan Lakshmi; Gurubaran, S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-28)
      Equatorial plasma bubbles resulting from equatorial spread urn:x-wiley:jgra:media:jgra55597:jgra55597-math-0002 are well known to be aligned along the Earth's geomagnetic fields. During the geomagnetic storm on 17 March 2015, all‐sky airglow observations from Tirunelveli (8.7°N, 77.8°E, 1.7°N dip latitude) showed an apparent interhemispheric asymmetry in the tilt of the equatorial plasma bubbles. ...
