      Koirala, Madhu; Ellingsen, Pål Gunnar; Ådland, Roar Os (Chapter; Bokkapittel, 2023-10-20)
      In this paper, we present a novel concept of tracking cargoes at open ports using remote sensing images and convolution neural network (CNN) to classify various dry bulk commodities. The dataset used is prepared using Sentinel-2 atmospherically corrected (Sentinel-2 L2A) images covering 12 spectral bands. There are total 4995 labeled and geo-referenced images for four different cargoes-bauxite, coal, ...

The qZSI is an economical solution for distributed generation and eliminates the need for two-stage power conversion. This article proposes a detailed step-wise digital controller design using a multi-loop control ...
    • Exploring learning in critical realism 

      Isaksen, Robert (Chapter; Bokkapittel, 2024)
      Critical realism is a philosophy of science, and not exclusively a theory of learning. However, because philosophic and scientific practice can be considered types of learning, a philosophy of science is likely either to have an implicit theory of learning or to have implications for learning theory, or both. In addition, as a philosophy of science, critical realism can provide general ...
    • Children and Youth at Risk in times of Transition. International and Interdisciplinary Perspectives 

      Ødegaard, Ingvill Constanze; Borge, Baard Herman; Kleinau, Elke (Book; Bok, 2023-12-04)
      Children and youth belong to one of the most vulnerable groups in societies. This was the case even before the current humanitarian crises around the world which led millions of people and families to flee from wars, terror, poverty and exploitation. Minors have been denied human rights such as access to education, food and health services. They have been kidnapped, sold, manipulated, mutilated, ...

This study explored the professional competencies teachers require when teaching diverse and multicultural pupils in the Circumpolar North drawing on the multiple affordances offered by the ...
    • Sea ice-ocean coupling during Heinrich Stadials in the Atlantic–Arctic gateway 

      el Bani Altuna, Naima; Mohamed, Mohamed Mahmoud Ezat Ahmed; Smik, Lukas; Muschitiello, Francesco; Belt, Simon T.; Knies, Jochen Manfred; Rasmussen, Tine Lander (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-11)
      The variability of Arctic sea-ice during abrupt stadial-interstadial shifts in the last glacial period remain poorly understood. Here, we investigated the millennial-scale relationship, with a focus on Heinrich Stadials (HS), between sea-ice cover and bottom water temperature (BWT) during Marine Isotope Stages (MIS) 3 and 2 (64–13 ka) in the Fram Strait using new molecular sea ice biomarker data and ...
    • Using the tectophase conceptual model to assess late Triassic–Early Jurassic far-field tectonism across the South-central Barents Sea shelf 

      Martins, Gustavo; Ettensohn, Frank R.; Knutsen, Stig Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-23)
      The Upper Triassic–Lower Jurassic succession of the Barents Sea Shelf (BSS) represents one of Europe’s most prolific and strategic petroleum systems. This succession reflects various depositional environments and tectonostratigraphic events. Even though these strata are considered largely well-understood, connections with far-field stresses triggered by regional tectonics remain a subject of ...

    • Teleological reasoning bias is predicted by pupil dynamics: Evidence for the extensive integration account of bias in reasoning 

      Mækelæ, Martin Jensen; Kreis, Isabel; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-28)
      Teleological reasoning is the tendency for humans to see purpose and intentionality in natural phenomena when there is none. In this study, we assess three competing theories on how bias in reasoning arises by examining performance on a teleological reasoning task while measuring pupil size and response times. We replicate that humans (N=45) are prone to accept false teleological explanations. Further, ...

    • Towards automatic generation of image recognition models for industrial robot arms 

      Arnarson, Halldor; Bremdal, Bernt Arild; Hanssen, Magnus Fredheim (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-12)
      As the world moves towards mass customization, there is a need for a manufacturing system that can quickly adapt to market changes. Reconfigurable manufacturing systems (RMS) have been proposed as a solution. RMS is designed to be modular with a high degree of flexibility. However, such a structure creates a lot of complexity. For instance, if the modules are moved or changed, the robot arms in the ...
