  • L-COMPLETE HOPF ALGEBROIDS AND THEIR COMODULES 
    Baker, Andrew (Research report / Forskningsrapport, 2009)
    We investigate Hopf algebroids in the category of <I>L</I>-complete modules over a commutative Noetherian regular complete local ring. The main examples of interest in algebraic topology are the Hopf algebroids associated ...
  • L^2-Betti Numbers of Algebras and Equivalence Relations 
    Rustad, Simen (Master thesis / Masteroppgave, 2008)
    In this thesis, we consider the L^2-Betti numbers associated to algebras and equivalence relations. For algebras, we expand upon the motivation between Connes and Shlyakhtenko's definition of L^2-Betti numbers of tracial ...
  • Laboratory evidence of freak waves provoked by non-uniform bathymetry 
    Trulsen, Karsten; Zeng, Huiming; Gramstad, Odin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    We show experimental evidence that as relatively long unidirectional waves propagate over a sloping bottom, from a deeper to a shallower domain, there can be a local maximum of kurtosis and skewness close to the shallower ...
  • Lagrangian based methods for finding MAP solutions for MRF models 
    Storvik, Geir; Dahl, Geir (Research report / Forskningsrapport, 1996)
  • The Landmark Approach Applied to Implied Volatility 
    Susrud, Andres Sørensen (Master thesis / Masteroppgave, 2012)
  • Large eddy simulations of a buoyant plume above a heated horizontal cylinder at intermediate Rayleigh numbers 
    Grafsrønningen, Stig; Jensen, Atle (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Large eddy simulations of a buoyant plume forming above a heated horizontal cylinder with a Rayleigh number of 9.4E7 is carried out and compared with experimental data. Natural convection heat transfer from a horizontal ...
  • A LARGE TIME-STEPPING SCHEME FOR BALANCE EQUATIONS 
    Karlsen, Kenneth H.; Mishra, Siddhartha; Risebro, Nils Henrik (Research report / Forskningsrapport, 2006)
    We present a well-balanced, large time stepping method for conservation laws with source terms. The numerical method is based on a local reformulation of the balance law as a conservation law with a discontinuous flux ...
  • Lastkapasitet for BubbleDeck påført punktlaster : SummaryRestricted Access 
    Heilmann, Eirik Torssønn (Master thesis / Masteroppgave, 2008)
    This paper is compilated as a masters degree assignment at the Faculty of Mathematics and Natural Science, University of Oslo. Today, Bubble Deck is used to reduce the net weight of a concrete slab. This is done by casting ...
  • Latent gaussian models to decide on spatial closures for bycatch management in the barents sea shrimp fishery 
    Breivik, Olav Nikolai; Storvik, Geir Olve; Nedreaas, Kjell Harald (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    In the Barents Sea and adjacent water, fishing grounds are closed for shrimp fishing by the Norwegian Directorate of Fisheries Monitoring and Surveillance Service (MSS) if the expected number of juvenile fish caught are ...
  • Latent Gaussian models to predict historical bycatch in commercial fishery 
    Breivik, Olav Nikolai; Storvik, Geir Olve; Nedreaas, Kjell Harald (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Knowledge about how many fish that have been killed due to bycatch is an important aspect of ensuring a sustainable ecosystem and fishery. We introduce a Bayesian spatio-temporal prediction method for historical bycatch ...
  • Least-squares fitting of Loop subdivision surfaces 
    Ringstad, Jonathan (Master thesis / Masteroppgave, 2017)
  • Lectures in optimum hypothesis testing theory 
    Bølviken, Erik (Research report / Forskningsrapport, 1992)
  • LEIBNIZ FORMULAS FOR CYCLIC HOMOTOPY FIXED POINT SPECTRA 
    Bruner, Robert R.; Rognes, John (Research report / Forskningsrapport, 2005)
  • Lévy Models Robustness and Sensitivy 
    Benth, Fred Espen; Di Nunno, Giulia; Khedher, Asma (Research report / Forskningsrapport, 2009)
    We study the robustness of the sensitivity with respect to parameters in expectation functionals with respect to various approximations of a Lévy process. As sensitivity parameter, we focus on the delta of an European ...
  • LÉVY-COPULA-DRIVEN FINANCIAL PROCESSES 
    Kettler, Paul C. (Research report / Forskningsrapport, 2006)
    This paper proposes a general non-Gaussian Ornstein-Uhlenbeck model for a joint financial process based on marginal Lévy measures joined by a Lévy copula. Simulated processes then result from choices of marginal measures ...
  • The libRadtran software package for radiative transfer calculations (version 2.0.1) 
    Emde, Claudia; Buras-Schnell, Robert; Kylling, Arve; Mayer, Bernhard; Gasteiger, Josef; Hamann, Ulrich; Kylling, Jonas Irgens; Richter, Bettina; Pause, Christian; Dowling, Timothy; Bugliaro, Luca (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    libRadtran is a widely used software package for radiative transfer calculations. It allows one to compute (polarized) radiances, irradiance, and actinic fluxes in the solar and thermal spectral regions. libRadtran has ...

    Willmann, Simon Caspar (Master thesis / Masteroppgave, 2012)
    This master's thesis studies the kayak rudder flow phenomena and uses analytic, numerical and experimental methods to describe the force coefficients of kayak rudders. Also an analysis of the sport of flatwater kayaking ...
