  • Arran, Matthew I.; Mangeney, Anne; De Rosny, Julien; Farin, Maxime; Toussaint, Renaud; Roche, Olivier (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Geophysical granular flows exert basal forces that generate seismic signals, which can be used to better monitor and model these severe natural hazards. A number of empirical relations and existing models link these signals' ...
  • Bertelsen, Håvard Svanes; Rogers, Benjamin David; Galland, Olivier; Dumazer, Guillaume Henri; Benanni, Alexandre Abbana (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The mechanics of magma emplacement in the Earth's crust corresponds to the flow of a viscous fluid into a deforming solid. The Earth's crust through which magma is emplaced is visco-elasto-plastic, and field observations ...
  • Oust, Bodil (Master thesis / Masteroppgave, 2009)
    Many of the patterns that can be observed in nature or in experiments are the result of surface instabilities. These structures typically arise when an interface is forced to move due to fluxes of heat and/or mass or because ...
  • Thorstensen, Jostein (Doctoral thesis / Doktoravhandling, 2013)
    Solar energy is rapidly becoming one of the most promising renewable energy sources available to us. Its abundant availability greatly surpasses any other energy source, and with the immense progress seen in production ...

    We present a laser-ionized, beam-driven, passive thin plasma lens that operates in the nonlinear blowout regime. This thin plasma lens provides axisymmetric focusing for relativistic electron beams at strengths unobtainable ...
  • Beneke, Martin; Bharucha, A.; Hryczuk, Andrzej Jan; Recksiegel, S; Ruiz-Femenia, P (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    We delineate the allowed parameter and mass range for a wino-like dark matter particle containing some Higgsino admixture in the MSSM by analysing the constraints from diffuse gamma-rays from the dwarf spheroidal galaxies, ...
  • Solli, Robert (Master thesis / Masteroppgave, 2019)
    In this thesis, we introduce the application of convolutional autoencoder neural networks to the analysis of two-dimensional projections of particle tracks from a resonant proton scattering experiment on 46Ar. We also build ...
  • Müting, Johanna; Bobal, Viktor; Sky, Thomas Neset; Vines, Lasse; Grossner, Ulrike (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The implantation of aluminum into 4H-SiC is studied using secondary ion mass spectrometry. In particular, two-dimensional concentration profiles are obtained, which allow the investigation of lateral straggling and its ...

  • Follestad, Anna Kristine Fæhn; Clausen, Lasse; Moen, Jøran Idar; Jacobsen, Knut Stanley (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The Norwegian Mapping Authority operates a network real time kinematic (RTK) system called CPOS, a positioning service providing centimeter level accuracy aimed at commercial users, for example, in civil engineering, ...
  • Tranås, Rasmus André; Løvvik, Ole Martin; Tomic, Oliver; Berland, Kristian (Journal article / Tidsskriftartikkel / SubmittedVersion, 2021)
    Low lattice thermal conductivity is essential for high thermoelectric performance of a material. Lattice thermal conductivity is often computed using density functional theory (DFT), typically at a high computational cost. ...
  • Eliassen, Simen Nut Hansen; Katre, Anikta; Madsen, Georg; Persson, Clas; Løvvik, Ole Martin; Berland, Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    In spite of their relatively high lattice thermal conductivity κℓ, the XNiSn (X=Ti, Zr, or Hf) half-Heusler compounds are good thermoelectric materials. Previous studies have shown that κℓ can be reduced by sublattice ...
  • Søvik, Åste (Master thesis / Hovedoppgave, 2002)
