    • Some new results and inequalities for subsequences of Nörlund logarithmic means of Walsh–Fourier series 

      Baramidze, David; Persson, Lars-Erik; Singh, Harpal; Tephnadze, George (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-07)
      We prove that there exists a martingale f ∈ H<sub>p</sub> such that the subsequence {L<sub>2n</sub f} of Nörlund logarithmic means with respect to the Walsh system are not bounded from the martingale Hardy spaces H<sub>p</sub> to the space weak – L<sub>p</sub> for 0 < p < 1. We also prove that for any f ∈ L<sub>p</sub>, p ≥ 1, L<sub>2n</sub> f converge to f at any Lebesgue point x. Moreover, ...
    • The importance of turbulent ocean–sea ice nutrient exchanges for simulation of ice algal biomass and production with CICE6.1 and Icepack 1.2 

      Duarte, Pedro; Assmy, Philipp; Campbell, Karley; Sundfjord, Arild (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-31)
      Different sea ice models apply unique approaches in the computation of nutrient diffusion between the ocean and the ice bottom, which are generally decoupled from the calculation of turbulent heat flux. A simple molecular diffusion formulation is often used. We argue that nutrient transfer from the ocean to sea ice should be as consistent as possible with heat transfer, since all of these fluxes ...
    • Towards an improved organic carbon budget for the western Barents Sea shelf 

      Pathirana, Irene Dorothea; Knies, Jochen; Felix, Maarten; Mann, Ute (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-03-21)
      There is generally a lack of knowledge on how marine organic carbon accumulation is linked to vertical export and primary productivity patterns in the Arctic Ocean. Despite the fact that annual primary production in the Arctic has increased as a consequence of shrinking sea ice, its effect on flux, preservation, and accumulation of organic carbon is still not well understood. In this study, a ...

As a tool to promote student activity, motivation, and learning, we developed and applied a new digital online teaching module in the subject nuclear medicine. In this study, we seek answers ...
    • Hvorfor undervise kanoniserte mannlige filosofers kjønnsperspektiver? Om universalitet og kjønnsnøytralitet i Aristoteles’, Kants og Mills etiske teorier 

      Nilsen, Fredrik (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-30)
      I artikkelen diskuterer jeg hvorfor vi bør undervise kanoniserte mannlige filosofers kjønnsperspektiver til examen philosophicum. Dette er ofte et neglisjert tema i lærebøker i filosofiens historie. Etter mitt syn finnes det i det minste tre grunner for inkludering av kjønnsperspektivene: For det første, har de kanoniserte mannlige filosofenes syn hatt avgjørende innflytelse på hvordan vi har ...
    • ‘Beyond my Control’: Dealing with the Existential Uncertainty of Cancer in Online Texts 

      Kvaale, Kaja; Lian, Olaug S.; Bondevik, Hilde (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-14)
      In this paper, we explore how existential aspects of being diagnosed and living with cancer are shared in stories that are publicly communicated online. Through a narrative analysis of online texts and blogs, we explore how people deal with their cancer experiences, how cultural norms about illness are expressed in their stories and why they write and publish their stories online. We found that the ...

    • Roach Infestation Optimization MPPT Algorithm for Solar Photovoltaic System 

      Calay, Rajnish K; Pradhan, Chittaranjan; Senapati, Manoj Kumar; Ntiakoh, Nicholas Kakra (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-16)
      Solar photovoltaic (PV) power has several advantages such as free availability, absence of rotating parts, can be easily integrated with building architecture, and need little maintenance. However, the PV cell current–voltage (I–V) characteristics are non-linear and power generated from a PV array depends on solar insolation/irradiation and panel temperature. The extracted PV output power is ...

    • A 30-year probability map for oil spill trajectories in the barents sea to assess potential environmental and socio-economic threats 

      Pavlov, Victor; Martins de Aguiar, Victor Cesar; Hole, Lars Robert; Pongrácz, Eva (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-24)
      Increasing exploration and exploitation activity in the Arctic Ocean has intensified maritime traffic in the Barents Sea. Due to the sparse population and insufficient oil spill response infrastructure on the extensive Barents Sea shoreline, it is necessary to address the possibility of offshore accidents and study hazards to the local environment and its resources. Simulations of surface oil ...
    • Symmetry gaps for higher order ordinary differential equations 

      Kessy, Johnson Allen; The, Dennis (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-04)
      The maximal contact symmetry dimensions for scalar ODEs of order ≥ 4 and vector ODEs of order ≥ 3 are well known. Using a Cartan-geometric approach, we determine for these ODEs the next largest realizable (submaximal) symmetry dimension. Moreover, finer curvature-constrained submaximal symmetry dimensions are also classified.
    • Benthic Biodiversity, Carbon Storage and the Potential for Increasing Negative Feedbacks on Climate Change in Shallow Waters of the Antarctic Peninsula

    • Deep Tower Networks for Efficient Temperature Forecasting from Multiple Data Sources 

      Eide, Siri Sofie; Riegler, Michael; Hammer, Hugo Lewi; Bremnes, John Bjørnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-06)
      Many data related problems involve handling multiple data streams of different types at the same time. These problems are both complex and challenging, and researchers often end up using only one modality or combining them via a late fusion based approach. To tackle this challenge, we develop and investigate the usefulness of a novel deep learning method called tower networks. This method is able ...
