    • A Golden-Channel Higgs Decay 

      Haarr, Anders (The University of Bergen, 2011-06-01)
      With a Higgs mass greater than 190 GeV and lower than 300 GeV, the decay channel H --> ZZ --> 4l becomes what is referred to as the golden channel for Higgs decay (clean signal). Suppose a pair of on shell Zs with ...

    • Graphical Computing Solution for Industrial Plant Engineering 

      Lima, Marcelo Furtado (The University of Bergen, 2017-06-21)
      When preparing an engineering operation on an industrial plant, reliable and updated models of the plant must be available for correct decisions and planning. However, especially in the case of offshore oil and gas ...

    • Gravitino dark matter and the flavour structure of R-violating operators 

      Bomark, Nils-Erik; Lola, Smaragda; Osland, Per; Raklev, Are Reinert (Elsevier, 2009-06-15)
      We study gravitino dark matter and slow gravitino decays within the framework of R-violating supersymmetry, with particular emphasis on the flavour dependence of the branching ratios and the allowed R-violating couplings. ...

    • Gravitino Dark Matter with Entropy Production constrained by Big Bang Nucleosynthesis 

      Høines, Håkon Vinje (The University of Bergen, 2016-12-16)
      We are looking at a gravitino dark matter scenario with a general neutralino next-to-lightest supersymmetric particle. We are considering the primary decay channels of the neutralino, and we define the supersymmetric ...

    • Gravity modeling: Calculations based on porosity-density context 

      Øvreeide, Anne (The University of Bergen, 2010-06-17)
      A normal way to model the gravity from a layered model is to determine the densities from the velocities, and then adjusting the densities within acceptable ranges to get a satisfactory fit with the observed gravity. In ...

    • Grein. A New Non-Linear Cryptoprimitive 

      Thorsen, Ole Rydland (The University of Bergen, 2013-12-10)
      In this thesis, we will study a new stream cipher, Grein, and a new cryptoprimitive used in this cipher. The second chapter gives a brief introduction to cryptography in general. The third chapter looks at stream ciphers ...

    • Grid sensitivity simulation of low salinity and polymer flooding 

      Nordaker, Vidar (The University of Bergen, 2015-05-31)
      Water flooding in a reservoir is a well- established recovery method used to maintain the reservoir pressure and to displace the oil towards the producing well. However, after water flooding there is still a ...

      Normann, John Andre (The University of Bergen and National Institute of Nutrition and Seafood Research (NIFES), 2014-02-25)
      Due to global warming, the sea water temperature will probably increase, which may affect cold- water species like Atlantic salmon. It is therefore of great importance to see how elevated temperature will affect the growth ...
