  • F. Wiener’s Trick and an Extremal Problem for Hp 
    Brevig, Ole Fredrik; Grepstad, Sigrid; Instanes, Sarah May (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
  • Face rings of Delta-sets with applications to degenerations of abelian surfaces 
    Stavnes, Jarle (Master thesis / Masteroppgave, 2014)
  • FACTORIZATION AND MULTIPLIERS OF SEGAL ALGEBRAS 
    Larsen, Ronald (Research report / Forskningsrapport, 1974)
  • Failure of the integral Hodge conjecture for threefolds of Kodaira dimension zero 
    Ottem, John Christian; Benoist, Olivier (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    We prove that the product of an Enriques surface and a very general curve of genus at least 1 does not satisfy the integral Hodge conjecture for 1-cycles. This provides the first examples of smooth projective complex ...
  • Fair Imputation: Reducing bias under missing data 
    Dioli, Marius Johan Franco (Master thesis / Masteroppgave, 2022)
  • Families of Proper Holomorphic Embeddings and Carleman-Type Theorem with parameters 
    Domenico Di Salvo, Giovanni; Ritter, Tyson; Wold, Erlend Fornæss (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    We solve the problem of simultaneously embedding properly holomorphically into C2 a whole family of n-connected domains Omega_r in P1 such that none of the components of P1 \ Omega_r reduces to a point, by constructing a ...
  • Fano congruences of index 3 and alternating 3-forms 
    Ranestad, Kristian; Mezzetti, Emilia; De Poi, Pietro; Faenzi, Daniele (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    We study congruences of lines Xω defined by a sufficiently general choice of an alternating 3-form ω in n dimensions, as Fano manifolds of index 3 and dimension n-1. These congruences include the G2-variety for n=6 and the ...
  • Fast Algorithms for Counting Points on Elliptic Curves over Finite Fields 
    Bocianowski, Sivert (Master thesis / Masteroppgave, 2019)
    Vi ser på Schoof's og Satoh's algoritmer for opptelling av rasjonale punkter på elliptiske kurver over endelige kropper. Relevant bakgrunn om elliptiske kurver og de p-adiske tallene. Kort om ECC (elliptic curve cryptography). ...
  • FAST COMPUTATION OF ARRIVAL TIMES IN HETEROGENEOUS MEDIA 
    Berre, Inga; Karlsen, Kenneth H.; Lie, K.-A.; Natvig, Bent (Research report / Forskningsrapport, 2003)
    We continue the work that was initiated in [7] on a fast marching-like method for simulating two-phase incompressible immiscible flow of water and oil in a porous medium. The purpose ot the present paper is threefold: (1) ...
  • A fast method for fully nonlinear water wave computations 
    Clamond, Didier; Grue, John (Research report / Forskningsrapport, 2000)
  • Fast parallel multidimensional FFT using advanced MPI 
    Dalcin, Lisandro; Mortensen, Mikael; Keyes, David (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    We present a new method for performing global redistributions of multidimensional arrays essential to parallel fast Fourier (or similar) transforms. Traditional methods use standard all-to-all collective communication of ...
  • Fatigue life extension using composite patch repairs 
    Rotwitt, Preben Brekke (Master thesis / Masteroppgave, 2013)
    The main objective of the present thesis was to study how composite patches can reduce the stress intensity in cracked steel plates, and how these patches, by reducing the stress intensity, can limit the extent of fatigue ...
  • A FATOU THEOREM FOR QUASIREGULAR FUNCTIONS 
    Øksendal, Bernt (Research report / Forskningsrapport, 1987)
  • Fault detection and diagnosis of nonlinear dynamical processes through correlation dimension and fractal analysis based dynamic kernel PCA 
    Bounoua, Wahiba; Bakdi, Azzeddine (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)
    A novel Dynamic Kernel PCA (DKPCA) method is developed for process monitoring in nonlinear dynamical systems. Classical DKPCA approaches still exhibit vague linearity assumptions to determine the number of principal ...
  • Fault-tolerant Coding for Quantum Communication 
    Christandl, Matthias; Müller-Hermes, Alexander (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)
    Designing encoding and decoding circuits to reliably send messages over many uses of a noisy channel is a central problem in communication theory. When studying the optimal transmission rates achievable with asymptotically ...
  • Favoring the hierarchical constraint in penalized survival models for randomized trials in precision medicine 
    Belhechmi, Shaima; Le Teuff, Gwénaël; De Bin, Riccardo; Rotolo, Federico; Michiels, Stefan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Background The research of biomarker-treatment interactions is commonly investigated in randomized clinical trials (RCT) for improving medicine precision. The hierarchical interaction constraint states that ...
  • Feilrettende koder 
    Halmrast, Balder Søholt (Master thesis / Masteroppgave, 2016)
    Denne oppgaven studerer Reed-Solomon-koder og ser på hvordan dekoding av disse kan relateres til å finne potenssumdekomposisjoner av polynomer, hvilket kan tolkes geometrisk som å finne et sekantplan til den rasjonale ...
  • A FEniCS based solver for actively contracting heart muscle tissueRestricted Access 
    Johansen, Anders Elstad (Master thesis / Masteroppgave, 2012)
    In this thesis we present a numerical solver for actively contracting heart muscle tissue. It uses the finite element method for the discretization and is entirely based on free open source software packages made available ...
