  • Modelling migration patterns of fish using depth and temperature preferences 

    Natvig, Erik (The University of Bergen, 2012-04-27)
    Time series of depth and temperature derived from electronic tagging of fish have been used to construct a stochastic model that aims at capturing main characteristics of the observations. Mixed Ornstein-Uhlenbeck process ...
  • Models and Solution Methods for the Pooling Problem 

    Alfaki, Mohammed (The University of Bergen, 2012-06-18)
    Pipeline transportation of natural gas is largely affected by restrictions regarding gas quality imposed by the market and the actual quality of the gas produced at sources. From the sources, gas flow streams of unequal ...
  • Modulation of Transcriptional and Inflammatory Responses in Murine Macrophages by the Mycobacterium tuberculosis Mammalian Cell Entry (Mce) 1 Complex 

    Stavrum, Ruth; Stavrum, Anne-Kristin; Valvatne, Håvard; Riley, Lee W.; Ulvestad, Elling; Jonassen, Inge; Assmus, Jørg; Doherty, Tanya Mark; Grewal, Harleen M. S. (Public Library of Science, 2011-10-24)
    The outcome of many infections depends on the initial interactions between agent and host. Aiming at elucidating the effect of the M. tuberculosis Mce1 protein complex on host transcriptional and immunological responses ...
  • Molecular mechanisms of adaptation emerging from the physics and evolution of nucleic acids and proteins 

    Goncearenco, Alexander; Ma, Binguang; Berezovsky, Igor (Oxford University Press, 2014)
    DNA, RNA and proteins are major biological macromolecules that coevolve and adapt to environments as components of one highly interconnected system. We explore here sequence/structure determinants of mechanisms of adaptation ...
  • Monte Carlo Study of the Formation and Conformational Properties of Dimers of Aβ42 Variants 

    Mitternacht, Simon; Staneva, Iskra; Härd, Torleif; Irbäck, Anders (Elsevier, 2011)
    Small soluble oligomers, and dimers in particular, of the amyloid β-peptide (Aβ) are believed to play an important pathological role in Alzheimer's disease. Here, we investigate the spontaneous dimerization of Aβ42, with ...
  • A Multilevel scheme for the Travelling Salesman Problem 

    Hjertenes, Øystein M. (The University of Bergen, 2002)
  • Multimedia i dynamisk presentasjons generator 2.0 

    Ingvaldsen, Bjørn Ove (The University of Bergen, 2008-10-01)
    Oppgaven omhandler en ny implementasjon av innholdshåndteringssystemet Dynamic Presetation Generator DPG, hvor hovedvekten av oppgaven tar for seg integrering av multimediafunksjonalitet i systemet.
  • Naturlige nettverk 

    Vatshelle, Martin (The University of Bergen, 2008)
    En innføring i naturlige nettverk. Vi forklarer og diskuterer begrepet naturlige nettverk og vurderer hvilke nettverk som bør kalles naturlige. Vi ser på forskjeller og likheter mellom tilfeldige, planlagte og naturlige ...
  • Network coding in Bluetooth networks 

    Stenvoll, Roger (The University of Bergen, 2009-10-01)
    This thesis discusses the possibility to apply network coding to a Bluetooth piconet. A protocol is proposed. This protocol is based on using deterministic linear network coding. The proposed alphabet size is binary, and ...
  • A New Generating Set Search Algorithm for Partially Separable Functions 

    Frimannslund, Lennart; Steihaug, Trond (IARIA, 2010)
    A new derivative-free optimization method for unconstrained optimization of partially separable functions is presented. Using average curvature information computed from sampled function values the method generates an ...
  • New Results on Minimal Triangulations 

    Villanger, Yngve (The University of Bergen, 2006-04-25)
  • New Width Parameters of Graphs 

    Vatshelle, Martin (The University of Bergen, 2012-09-03)
    The main focus of this thesis is on using the divide and conquer technique to efficiently solve graph problems that are in general intractable. We work in the field of parameterized algorithms, using width parameters of ...
  • A Note on Exact Algorithms for Vertex Ordering Problems on Graphs 

    Bodlaender, Hans L.; Fomin, Fedor V.; Koster, Arie M.C.A.; Kratsch, Dieter; Thilikos, Dimitrios M. (Springer, 2011-01-21)
    In this note, we give a proof that several vertex ordering problems can be solved in O ∗(2 n ) time and O ∗(2 n ) space, or in O ∗(4 n ) time and polynomial space. The algorithms generalize algorithms for the Travelling ...
  • Novice Difficulties with Language Constructs 

    Rosbach, Alexander Hoem (The University of Bergen, 2013-08-01)
    Programming is a difficult skill to learn, and programming courses have high dropout rates. In this thesis we study the problems that students have during their first introductory programming course at The University ...
