    Groot, Diane (Doctoral thesis; Doktorgradsavhandling, 2014-09-26)
    This thesis aimed at enhancing our understanding of the oceanographic variability of the Nordic Seas during the last 11,000 years. The Nordic Seas are a key area within the Atlantic Meridional Overturning Circulation (AMOC), ...
  • Parameter-Free Extended Edit Distance 

    Muhammad Fuad, Muhammad Marwan (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
    The edit distance is the most famous distance to compute the similarity between two strings of characters. The main drawback of the edit distance is that it is based on local procedures which reflect only a local view of ...
  • Particle precipitation : effects on selected ionospheric phenomena 

    Lunde, June (Doctoral thesis; Doktorgradsavhandling, 2009-11-26)
    The motivation behind this thesis has been to study particle precipitation from the Sun into the Earth’s upper atmosphere and its effects on selected ionospheric phenomena. Particles from the solar wind can enter the Earth's ...
  • Particle precipitation during NEIAL events : simultaneous ground based nighttime observations at Svalbard 

    Lunde, June; Løvhaug, Unni Pia; Gustavsson, Björn Johan (Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
  • Particle precipitations during NEIAL events : simultaneous ground based observations at Svalbard 

    Lorentzen, Dag Arne; Lunde, June; Ogawa, Y; Gustavsson, B; Løvhaug, U.P.; Ogawa, Yasunobu (Journal article; Tidsskriftartikkel; Peer reviewed, 2007)
    In this paper we present Naturally Enhanced Ion Acoustic Lines (NEIALs) observed with the EISCAT Svalbard Radar (ESR). For the first time, long sequences of NEIALs are recorded, with more than 50 events within an hour, ...
  • Particle tracking in 3D 

    Brox, Petter (Master thesis; Mastergradsoppgave, 2013-06)
    The evanescent field of an optical waveguide can be used to trap and propel microscopic particles. A 1µm particle is trapped on a strip waveguide and propelled forward until it reaches a 10µm gap at the centre of a loop, ...
  • Performance experiments with the Storm View Distributed Parallel Volume Renderer. 

    Asplin, Jo; Johansen, Dag (Research report; Forskningsrapport, 1995-06)
    Volume rendering is a useful but cpu-intensive method for visualizing large scalar fields. The time to render a single image may be reduced by parallel processing. This paper reports on performance experiments with the ...
  • Performance isolation and adaption in the Vortex Kernel 

    Kvalnes, Aage; Renesse, Robbert van; Johansen, Dag (Research report; Forskningsrapport, 2003-01-10)
    Vortex is a new multiprocessor operating system kernel intended for emerging Internet service applications. The architecture is based on SEDA's staged computational model. Vortex provides mechanisms for performance isolation ...
