  • Exact Solutions of the Field Equations for Empty Space in the Nash Gravitational Theory 

    Aadne, Matthew Terje; Grøn, Øyvind (Journal article; Peer reviewed, 2017-02)
    John Nash has proposed a new theory of gravity. We define a Nash-tensor equal to the curvature tensor appearing in the Nash field equations for empty space, and calculate its components for two cases: 1. A static, spherically ...

    We investigate a class of multi-dimensional two-component systems of Monge-Ampère type that can be viewed as generalisations of heavenly type equations appearing in a self-dual Ricci-flat geometry. Based on the Jordan-Kronecker ...
  • Scattering amplitudes of massive Nambu-Goldstone bosons 

    Brauner, Tomas; Jakobsen, Martin Fonnum (Journal article; Peer reviewed, 2018-01)
    Massive Nambu-Goldstone (mNG) bosons are quasiparticles the gap of which is determined exactly by symmetry. They appear whenever a symmetry is broken spontaneously in the ground state of a quantum many-body system and at ...
  • Hva skal til for at arbeidstakere skal spare riktig til egen pensjon? 

    Tonning, Sølvi Marie (Masteroppgave/UIS-TN-IØRP/2017;, Master thesis, 2017-10-12)
    Denne oppgaven ser på risikoen for å bli en fattig pensjonist og hva som skal til for å redusere risikoen. Endringer i pensjonssystemet har ført til at unge i dag vil få langt lavere pensjonsutbetaling fra Folketrygden ...
  • Molecular Characterization of the Plastid-localized ABC Protein TAP1 in Arabidopsis thaliana 

    Hempel, Jan Johansen (PhD thesis UiS;375, Doctoral thesis, 2018-01)
    The two TAP-like genes, AtTAP1 and AtTAP2, belong to the ABC transporter superfamily of Arabidopsis. AtTAP2/ALS1 has been shown to be important for aluminum metabolism and tolerance, however, little is known about the ...
  • Informasjonssikkerhet i et samfunnsperspektiv 

    Refsland, Laila (Masteroppgave/UIS-SV-IMKS/2017;, Master thesis, 2017-10)
    Bakgrunn for denne oppgaven startet som en nysgjerrighet til informasjonssikkerhet og dette med sikring/Security. Det har vært mye oppe i media om hendelser fra flere bransjer og ønsket å se på dette med informasjonssikkerhet ...
  • An exponential time-differencing method for monotonic relaxation systems 

    Aursand, Peder; Evje, Steinar; Flåtten, Tore; Teigen, Knut Erik; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2014)
    We present first and second-order accurate exponential time differencing methods for a special class of stiff ODEs, denoted as monotonic relaxation ODEs. Some desirable accuracy and robustness properties of our methods are ...
  • On-shell parameter fixing in the quark-meson model 

    Adhikari, Prabal; Andersen, Jens Oluf; Kneschke, Patrick (Journal article; Peer reviewed, 2017-02)
    The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ...
  • Variable setpoint as a relaxing component in physiological control 

    Risvoll, Geir; Thorsen, Kristian; Ruoff, Peter; Drengstig, Tormod (Journal article; Peer reviewed, 2017-09)
    Setpoints in physiology have been a puzzle for decades, and especially the notion of fixed or variable setpoints have received much attention. In this paper, we show how previously presented homeostatic controller motifs, ...
