    • Frequency-dependent magnetizability 

      Anelli, Marco (Master thesis; Mastergradsoppgave, 2010-11-15)
      This work discusses the theory of the magnetizability. The magnetizability is a molecular property defined as the second-order perturbation of the energy in the presence of an external magnetic field. When the magnetic ...

      Moumets, Heike (Master thesis; Mastergradsoppgave, 2008-12-15)
      The Fugløy area is located on the south-western Barents Sea shelf, in northern Norway. Multibeam echosounder bathymetry data, backscatter data and high-resolution seismic profiles were used to identify cold-water coral ...
    • Functional Knowledge Transfer for High-accuracy Prediction of Under-studied Biological Processes 

      Park, Christopher Y.; Wong, Aaron K.; Greene, Casey S.; Rowland, Jessica; Guan, Yuanfang; Bongo, Lars Ailo; Burdine, Rebecca D.; Troyanskaya, Olga (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      A key challenge in genetics is identifying the functional roles of genes in pathways. Numerous functional genomics techniques (e.g. machine learning) that predict protein function have been developed to address this ...
    • Fysikk i den polare atmosfæren og nordlyset 

      Brekke, Asgeir (Research report; Forskningsrapport, 2008)
      Den polare atmosfæren har fått mer oppmerksomhet i den senere tid enn den vanligvis har vært forunt. Dette henger sammen med tanken om at den er så ren og upåvirket av eventuelle forurensninger som vi pumper ut i atmosfæren ...
    • Gamle olje- og gass-lekkasjer i Barentshavet 

      Vorren, Tore Ola; Laberg, Jan Sverre (Chronicle; Kronikk, 2010-08-28)
    • A gas-hydrate related BSR on the W-Svalbard margin: distribution, geological control and formation mechanisms 

      Vevik, Kristine (Master thesis; Mastergradsoppgave, 2011-06-15)
      A widespread bottom-simulating reflection (BSR) defining the base of the gas hydrate stability zone (BGHSZ) exists on seismic data from the western Svalbard margin, including the Vestnesa Ridge, which is a mounded and ...
    • Gauge-origin independent calculations of Jones birefringence 

      Shcherbin, Dmitri; Thorvaldsen, Andreas johan; Jonsson, Dan Johan; Ruud, Kenneth (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      We present the first gauge-origin independent formulation of Jones birefringence at the Hartree–Fock level of theory. Gauge-origin independence is achieved through the use of London atomic orbitals. The implementation is ...
    • A generalization of Kung’s theorem 

      Johnsen, Trygve; Shiromoto, Keisuke; Verdure, Hugues (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-01)
      We give a generalization of Kung’s theorem on critical exponents of linear codes over a finite field, in terms of sums of extended weight polynomials of linear codes. For all i=k+1,…,ni=k+1,…,n, we give an upper bound on ...
    • A generalization of weight polynomials to matroids 

      Johnsen, Trygve; Roksvold, Jan Nyquist; Verdure, Hugues (Tidsskriftartikkel; Peer reviewed, 2015-11-11)
      Generalizing polynomials previously studied in the context of linear codes, we define weight polynomials and an enumerator for a matroid M. Our main result is that these polynomials are determined by Betti numbers associated ...
    • Generation of the lower-thermospheric vertical wind estimated with the EISCAT KST radar at high latitudes during periods of moderate geomagnetic disturbance 

      Brekke, Asgeir; Oyama, S; Watkins, B. J.; Maeda, S.; Shinagawa, H.; Nozawa, S.; Ogawa, Y.; Lathuillere, C.; Kofman, W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-06-11)
      Lower-thermospheric winds at high latitudes during moderately-disturbed geomagnetic conditions were studied using data obtained with the European Incoherent Scatter (EISCAT) Kiruna-Sodankylä-Tromsø (KST) ultrahigh frequency ...
    • Geodesic Webs and PDE Systems of Euler Equations 

      Goldberg, Vladislav V.; Lychagin, Valentin V. (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-10-30)
      We find necessary and sufficient conditions for the foliation defined by level sets of a function f(x1, ..., xn) to be totally geodesic in a torsion-free connection and apply them to find the conditions for d-webs of ...
    • Geodesic Webs of Hypersurfaces 

      Lychagin, Valentin V.; Goldberg, Vladislav V. (Working paper; Arbeidsnotat, 2008-12-11)
      In the present paper we study geometric structures associated with webs of hypersurfaces. We prove that with any geodesic (n + 2)-web on an n-dimensional manifold there is naturally associated a unique projective structure ...
    • Geodesic Webs on a Two-Dimensional Manifold and Euler Equations 

      Goldberg, Vladislav V.; Lychagin, Valentin V. (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-10-30)
      We prove that any planar 4-web defines a unique projective structure in the plane in such a way that the leaves of the web foliations are geodesics of this projective structure. We also find conditions for the projective ...
