    • Forståelse av matematiske tekstoppgaver. Hva bør man som lærer ha tenkt gjennom når man ønsker at elevene skal jobbe med tekstoppgaver i matematikk? 

      Stordrange, Kjetil Kjellesvik (Master thesis, 2018-06-21)
      Denne studien tar for seg matematiske tekstoppgavers oppbygning og ser på ulike typer utfordringer elever kommer over i møte med tekstoppgaver. Utfordringene handler i stor grad om det å oversette teksten i tekstoppgaver ...
    • Fourier analysis on abelian groups; theory and applications 

      Odland, Tommy (Master thesis, 2017)
      Fourier analysis expresses a function as a weighted sum of complex exponentials. The Fourier machinery can be applied when a function is defined on a locally compact abelian group (LCA). The groups R, T = R / Z, Z and Z_n ...
    • Fractal structures in freezing brine 

      Alyaev, Sergey; Keilegavlen, Eirik; Nordbotten, Jan Martin; Pop, Iuliu Sorin (Peer reviewed; Journal article, 2017-09)
      The process of initial ice formation in brine is a highly complex problem. In this paper, we propose a mathematical model that captures the dynamics of nucleation and development of ice inclusions in brine. The primary ...

    • Fronts in two-phase porous media flow problems: The effects of hysteresis and dynamic capillarity 

      Mitra, K; Köppl, T.; Pop, Iuliu Sorin; van Duijn, Duijn; Helmig, Rainer (Journal article; Peer reviewed, 2020)
      In this work, we study the behavior of saturation fronts for two-phase flow through a long homogeneous porous column . In particular, the model includes hysteresis and dynamic effects in the capillary pressure and hysteresis ...
    • Full family of flattening solitary waves for the critical generalized KdV equation 

      Martel, Yvan; Pilod, Didier Jacques Francois (Journal article; Peer reviewed, 2020)
      For the critical generalized KdV equation ∂tu+∂x(∂2xu+u5)=0 on R, we construct a full family of flattening solitary wave solutions. Let Q be the unique even positive solution of Q′′+Q5=Q. For any ν∈(0,13), there exist ...
    • Fully Automatic Whole-Volume Tumor Segmentation in Cervical Cancer 

      Hodneland, Erlend; Kaliyugarasan, Sathiesh Kumar; Wagner-Larsen, Kari Strøno; Lura, Njål Gjærde; Andersen, Erling; Bartsch, Hauke; Smit, Noeska Natasja; Halle, Mari Kyllesø; Krakstad, Camilla; Lundervold, Alexander Selvikvåg; Haldorsen, Ingfrid S. (Journal article; Peer reviewed, 2022-05-11)
      Uterine cervical cancer (CC) is the most common gynecologic malignancy worldwide. Whole-volume radiomic profiling from pelvic MRI may yield prognostic markers for tailoring treatment in CC. However, radiomic profiling ...
    • A fully coupled numerical model of thermo-hydro-mechanical processes and fracture contact mechanics in porous media 

      Stefansson, Ivar; Keilegavlen, Eirik; Berre, Inga (Journal article; Peer reviewed, 2021)
      Various phenomena in the subsurface are characterised by the interplay between deforming structures such as fractures and coupled thermal, hydraulic and mechanical processes. Simulation of subsurface dynamics can provide ...
    • Fully dispersive water wave equations 

      Dinvay, Evgueni (Doctoral thesis, 2020-02-21)
      The PhD project concerns the surface water wave theory. Liquid is presented as a three or two dimensional layer bounded from below by a rigid horizontal bottom. Above it can have either a free surface or an elastic layer ...
    • Fully-implicit simulation of vertical-equilibrium models with hysteresis and capillary fringe 

      Nilsen, Halvor Møll; Lie, Knut-Andreas; Andersen, Odd (Peer reviewed; Journal article, 2016-02)
      Geological carbon storage represents a new and substantial challenge for the subsurface geosciences. To increase understanding and make good engineering decisions, containment processes and large-scale storage operations ...
    • Functional analysis and exterior calculus on mixed-dimensional geometries 

      Boon, Wietse; Nordbotten, Jan Martin; Vatne, Jon Eivind (Journal article; Peer reviewed, 2020-07-12)
      We are interested in differential forms on mixed-dimensional geometries, in the sense of a domain containing sets of d-dimensional manifolds, structured hierarchically so that each d-dimensional manifold is contained in ...
    • Functional inequalities on path space of sub-Riemannian manifolds and applications 

      Cheng, Li-Juan; Grong, Erlend; Thalmaier, Anton (Journal article; Peer reviewed, 2021)
      We consider the path space of a manifold with a measure induced by a stochastic flow with an infinitesimal generator that is hypoelliptic, but not elliptic. These generators can be seen as sub-Laplacians of a sub-Riemannian ...
