  • Moldestad, Johan; Normann, Dag (Research report / Forskningsrapport, 1974)
  • Jahren, Bjørn; Kwasik, Slawomir (Research report / Forskningsrapport, 2000)
  • De Poi, Pietro (Research report / Forskningsrapport, 2001)
    In this article we classify all the smooth 3-folds of P5 with an apparent 4-tuple point provided that the family of its 4-secant lines is an irreducible (first order) congruence. This is sufficient to conclude the ...
  • Frøyshov, Kim Anders (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2012)
    We extend Donaldson’s diagonalization theorem to intersection forms with certain local coefficients, under some constraints. This provides new examples of non-smoothable topological 4–manifolds.
  • Lindbæck, Astri Strand (Master thesis / Masteroppgave, 2015)
    Punktene på en elliptisk kurve danner en gruppe. Hvis vi kaller origo i gruppa for Q, er et n-torsjonspunkt et punkt P som er slik at nP=Q. Mengden n-torsjonspunkter danner en abelsk gruppe. Alle 3-torsjonspunktene på en ...
  • Skauli, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We apply the specialization technique based on the decomposition of the diagonal to the intersection of a quadric and cubic hypersurface in P6. We find an explicit example defined over Q that is smooth, and does not admit ...
  • Koch, Timo; Weishaupt, Kilian; Müller, Johannes; Weigand, Bernhard; Helmig, Rainer (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Abstract We present a dual network model to simulate coupled single-phase flow and energy transport in porous media including conditions under which local thermal equilibrium cannot be assumed. The models target applications ...
  • Graff, Michael (Master thesis / Masteroppgave, 2014)
    The Icelandic population is scarce compared to the Norwegian, causing high variability in the observed mortalities. We apply two mortality models to data on the Norwegian population dating 60 years back, and the Icelandic ...
  • Hubin, Aliaksandr; Storvik, Geir Olve; Grini, Paul Eivind; Butenko, Melinka Alonso (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Epigenetic observations are represented by the total number of reads from a given pool of cells and the number of methylated reads, making it reasonable to model this data by a binomial distribution. There are numerous ...
  • Haselsteiner, Andreas F.; Coe, Ryan G.; Manuel, Lance; Chai, Wei; Leira, Bernt Johan; Clarindo, Guilherme; Soares, Carlos Guedes; Hannesdóttir, Ásta; Dimitrov, Nikolay; Sander, Aljoscha; Ohlendorf, Jan-Hendrik; Thoben, Klaus-Dieter; Hauteclocque, Guillaume de; Mackay, Ed; Jonathan, Philip; Qiao, Chi; Myers, Andrew; Rode, Anna; Hildebrandt, Arndt; Schmidt, Boso; Vanem, Erik; Huseby, Arne Bang (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Environmental contours are used to simplify the process of design response analysis. A wide variety of contour methods exist; however, there have been a very limited number of comparisons of these methods to date. This ...
  • Shaw, Kristin; Brugallé, Erwan (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2014)
    This friendly introduction to tropical geometry is meant to be accessible to first year students in mathematics. The topics discussed here are basic tropical algebra, tropical plane curves, some tropical intersections, and ...
  • De Bin, Riccardo; Stikbakke, Vegard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    In this paper we propose a boosting algorithm to extend the applicability of a first hitting time model to high-dimensional frameworks. Based on an underlying stochastic process, first hitting time models do not require ...
  • Floater, Michael S. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    We consider spline functions over simplicial meshes in Rn. We assume that the spline pieces join together with some finite order of smoothness but the pieces themselves are infinitely smooth. Such splines can have extra ...
  • Akbar, Rahmad; Robert, Philippe Paul Auguste; Pavlović, Milena; Jeliazkov, Jeliazko R.; Snapkov, Igor; Slabodkin, Andrei; Weber, Cédric R.; Scheffer, Lonneke; Miho, Enkelejda; Haff, Ingrid Hobæk; Haug, Dag Trygve Truslew; Lund-Johansen, Fridtjof; Safonova, Yana; Sandve, Geir Kjetil Ferkingstad; Greiff, Victor (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Antibody-antigen binding relies on the specific interaction of amino acids at the paratope-epitope interface. The predictability of antibody-antigen binding is a prerequisite for de novo antibody and (neo-)epitope design. ...
  • Corcuera, José Manuel; Di Nunno, Giulia; Farkas, Gergely; Øksendal, Bernt (Research report / Forskningsrapport, 2014)
  • Chatterjee, Neelabja; Fjordholm, Ulrik Skre (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    We derive and study a Lax–Friedrichs-type finite volume method for a large class of nonlocal continuity equations in multiple dimensions. We prove that the method converges weakly to the measure-valued solution and converges ...
  • Brevig, Ole Fredrik; Ortega-Cerdà, Joaquim; Seip, Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    A sharp version of a recent inequality of Kovalev and Yang on the ratio of the (H1)∗ and H4 norms for certain polynomials is obtained. The inequality is applied to establish a sharp and tractable sufficient condition for ...
  • Ottem, John Christian; Rennemo, Jørgen Vold (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    The Grassmannian Gr(2,5) is embedded in ℙ9 via the Pl\"ucker embedding. The intersection of two general PGL(10)-translates of Gr(2,5) is a Calabi-Yau 3-fold X, and the intersection of the projective duals of the two ...
  • Bakdi, Azzeddine; Kouadri, Abdelmalek; Mekhilef, Saad (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Advanced Fault Detection (FD) and isolation schemes are necessary to realize the required levels of reliability and availability and to minimize financial losses against failures. In particular, FD is essential in modern ...
