• Paradulichia spinifera gurjanova, 1946 (Amphipoda, dulichiidae), a valid species? 

    Johansen, Per-Otto; Vader, Wim (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-11)
    Examination of Paradulichia-material collected from the Barents Sea during the Mareano cruises indicated that there are clear morphological differences between Paradulichia typica Boeck, 1871 from the Hardangerfjord, W. Norway and Paradulichia spinifera Gurjanova, 1946 from the Arctic. Based on our material and the original descriptions, these differences are the acute ventral parts of the body ...
  • New Corrole Analogues: Isocorroles and Azulicorrole 

    Larsen, Simon (Doctoral thesis; Doktorgradsavhandling, 2020-02-25)
    Porphyrinoids are a family of molecules, which consist of large ring structures or macrocycles. One of the oldest, and most important, of the porphyrinoids is the biological molecule called porphyrin. Since the dawn of life, porphyrins have orchestrated photosynthesis and oxygen respiration, two of the most important energy-generating processes in nature. In addition to porphyrins, other porphyrinoids ...
  • Ant colony optimization and analysis of time step resolution in transmission expansion computations for wind power integration 

    Fuchs, Ida; Gjengedal, Terje (Chapter; Bokkapittel, 2011)
    This paper investigates the necessary time step resolution in a transmission expansion planning algorithm based on ant colony optimization. A maximal and efficient wind power integration is the main motivation for the grid expansion, which requires a planning tool dealing with wind energy fluctuations. For the analysis a power system model for the Nordic area is used, including a wind power ...
  • Relationship between the source size at the diffuser plane and the longitudinal spatial coherence function of the optical coherence microscopy system 

    Usmani, Kashif; Ahmad, Azeem; Joshi, Rakesh; Dubey, Vishesh Kumar; Butola, Ankit; Mehta, Dalip Singh (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-25)
    Coherence properties of light sources are indispensable for optical coherence microscopy/tomography as they greatly influence the signal-to-noise ratio, axial resolution, and penetration depth of the system. In the present paper, we report the investigation of longitudinal spatial coherence properties of a pseudothermal light source (PTS) as a function of the laser spot size at the rotating diffuser ...
  • Progradation rates measured at modern river outlets: A first-order constraint on the pace of deltaic deposition 

    Aadland, Tore; Helland-Hansen, William (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-29)
    We present a compilation of modern shoreline progradation rates measured close to river outlets entering deltaic coastlines, and we discuss how these observations relate to the overall evolution of both modern and ancient deltaic coastlines. We analyzed Landsat‐derived satellite images to identify plan view changes in the subaerial morphology of 331 modern deltaic coastlines. Our rate compilation ...
