  • Hassanzadeh, Seyed Mehdi Mohammad (Doctoral thesis, The University of Bergen, 2011-09-09)
    This thesis has focused on the cryptanalysis of cryptographic primitives especially stream ciphers which is an important topic in cryptography. Additionally, the security of network coding is discussed and improved with ...
  • Lampe, Ove Daae; Correa, Carlos; Ma, Kwan-Liu; Hauser, Helwig (Peer reviewed; Journal article, IEEE, 2009-10-11)
    We present two visualization techniques for curve-centric volume reformation with the aim to create compelling comparative visualizations. A curve-centric volume reformation deforms a volume, with regards to a curve in ...
  • Lampe, Ove Daae; Hauser, Helwig (Peer reviewed; Journal article, Blackwell publishing, 2011-06-28)
    In this work, we present a technique based on kernel density estimation for rendering smooth curves. With this approach, we produce uncluttered and expressive pictures, revealing frequency information about one, or, ...
  • Kvalsund, Øyvind Westgaard (Master thesis, The University of Bergen, 2008)
    Balter Medical har laget løsning der en kan påvise melanom i huden ved hjelp av bildediagnostikk. Denne diagnostiseringsmetoden genererer mye data, i form av bilder og informasjon knyttet til pasient. Dette har vært lagret ...
  • Abdelraheem, Mohamed Ahmed Awadelkareem M.A (Master thesis, The University of Bergen, 2009-03-26)
    In this thesis, we study spectral measures of Boolean functions. In the first half of thesis, we study the Walsh spectrum and the periodic autocorrelation spectrum of a Boolean function. A database of Boolean functions is ...
  • Høiland, Morten (Master thesis, The University of Bergen, 2011-06-01)
  • Sztromwasser, Paweł; Puntervoll, Pål; Petersen, Kjell (Journal article, IMBio e.V., 2011)
    Biological databases and computational biology tools are provided by research groups around the world, and made accessible on the Web. Combining these resources is a com- mon practice in bioinformatics, but integration ...
  • Nyero, Walter (Master thesis, The University of Bergen, 2009-11-20)
    Today many organisations and enterprises are using data from several sources either for strategic decision making or other business goals such as data integration. Data quality problems are always a hindrance to effective ...
  • Grønning, Torgeir Mossige (Master thesis, The University of Bergen, 2013-06-02)
    A prototype Web--GIS system has been constructed as a replacement for the ageing ODB system. It consists of a software stack with PostGIS as a data store, GeoServer as a data accessor and a client implemented in JavaScript ...
  • Tellnes, Jørgen (Master thesis, The University of Bergen, 2013-10-15)
    In the past years, package managers, application frameworks and open-source libraries have made it vastly simpler and faster to get functioning software up and running, while cloud providers and external service providers ...
  • Dorn, Frederic (Doctoral thesis, The University of Bergen, 2007-09-14)
    In this thesis we focus on subexponential algorithms for NP-hard graph problems: exact and parameterized algorithms that have a truly subexponential running time behavior. For input instances of size n we study exact ...
  • Dysvik, Bjarte (Doctoral thesis, The University of Bergen, 2006-10-20)
  • Barsnes, Harald (Doctoral thesis, The University of Bergen, 2010-03-22)
  • Rutle, Adrian (Doctoral thesis, The University of Bergen, 2010-11-29)
    Model-driven engineering (MDE) is a software engineering discipline which promotes models as first-class entities. It represents a shift of paradigm in software development, from being code-centric to become model-centric. ...
  • Rossini, Alessandro (Doctoral thesis, The University of Bergen, 2011-12-07)
    Model-driven engineering (MDE) is a branch of software engineering which aims at improving the productivity, quality and cost-effectiveness of software by shifting the paradigm from code-centric to model-centric. MDE ...
  • Hojsík, Michal; Rudolf, Bohuslav (Chapter; Peer reviewed, Springer Berlin Heidelberg, 2008)
    Trivium is a hardware-oriented stream cipher designed in 2005 by de Canni`ere and Preneel for the European project eStream, and it has successfully passed the first and the second phase of this project. Its design has ...
  • Subramanian, Sattanathan; Sztromwasser, Paweł; Puntervoll, Pål; Petersen, Kjell (Conference object, ACM, 2012)
    In scientific data analysis, workflows are used to integrate and coordinate resources such as databases and tools. Workflows are normally executed by an orchestrator that invokes component services and mediates data ...
  • Danielsen, Lars Eirik; Parker, Matthew G. (Peer reviewed; Journal article, Springer, 2010)
    We show that (n, 2n) additive codes over GF(4) can be represented as directed graphs. This generalizes earlier results on self-dual additive codes over GF(4), which correspond to undirected graphs. Graph representation ...
  • Bergmann, Ørjan (Master thesis, The University of Bergen, 2002)
  • Riskedal, Espen (Master thesis, The University of Bergen, 2002)
    This thesis studies drumloops, and the possibility to separate the different drumsounds from each other. Drum onsets and the detection of these are thoroughly discussed. Different approaches for detection and separation ...
