  • Ruiz; Marc; Boada, Imma; Viola, Ivan; Bruckner, Stefan; Feixas, Miquel; Sbert, Mateu (Peer reviewed; Conference object, The Eurographics Association, 2008)
    lighting effects in a faster way than global illumination. Its application in volume visualization is of special interest since it permits us to generate a high quality rendering at a low cost. In this paper, we propose ...
  • Barsnes, Harald; Côté, Richard G.; Eidhammer, Ingvar; Martens, Lennart (Journal article; Peer reviewed, BioMed Central, 2010-01-17)
    Background: With the growing amount of biomedical data available in public databases it has become increasingly important to annotate data in a consistent way in order to allow easy access to this rich source of information. ...

  • Frimannslund, Lennart; Steihaug, Trond (Journal article, IARIA, 2011)
    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 ...
  • Danielsen, Lars Eirik (Doctoral thesis, The University of Bergen, 2008-05-28)
    We study objects that can be represented as graphs, error-correcting codes, quantum states, or Boolean functions. It is known that self-dual additive codes, which can also be interpreted as quantum states, can be ...
  • Frimannslund, Lennart (Doctoral thesis, The University of Bergen, 2006-06-16)
  • Knudsen, Joakim Grahl (Doctoral thesis, The University of Bergen, 2010-11-24)
    The overall topic of this work is a graph operation known as edgelocal complementation (ELC) and its applications to iterative decoding of classical codes. Although these legacy codes are arguably not well-suited for ...
  • Danielsen, Lars Eirik (Master thesis, The University of Bergen, 2005)
    A short introduction to quantum error correction is given, and it is shown that zero-dimensional quantum codes can be represented as self-dual additive codes over GF(4) and also as graphs. We show that graphs representing ...
  • Danielsen, Lars Eirik (Peer reviewed; Journal article, Institute of Electrical and Electronics Engineers, 2012-08)
    Additive codes over GF(9) that are self-dual with respect to the Hermitian trace inner product have a natural application in quantum information theory, where they correspond to ternary quantum error-correcting codes. ...
  • Abyaneh, Mohammad Reza Sohizadeh (Conference object, The author, 2012)
    In this paper, the privacy of two recent RFID tag ownership transfer protocols are investigated against the tag owners as adversaries. The first protocol called ROTIV is a scheme which provides a privacy-preserving ...
  • Abyaneh, Mohammad Reza Sohizadeh (Conference object, The author, 2012)
    As a variant of the HB authentication protocol for RFID systems, which relies on the complexity of decoding linear codes against passive attacks, Madhavan et al. presented Non-Linear HB(NLHB) protocol. In contrast to ...
  • Cabello, Adán; Danielsen, Lars Eirik; López-Tarrida, Antonio J.; Portillo, José R. (Peer reviewed; Journal article, American Physical Society, 2011-04-12)
    We show how to prepare any graph state of up to 12 qubits with: (a) the minimum number of controlled-Z gates, and (b) the minimum preparation depth. We assume only one-qubit and controlled-Z gates. The method exploits ...
  • Bergmann, Ørjan (Doctoral thesis, The University of Bergen, 2008-02-27)
    Fiber tracking is a relatively recent methodology, made possible by access to new highly advanced MR scanners able to produce high-quality diffusion tensor images (DTI), which promises clinicians a possibility to observe ...
  • Haugland, Jan Kristian (Master thesis, The University of Bergen, 2012-05-24)
    The topic of this thesis is wind farm optimization. The goal is to be able to decide where to install wind turbines within a given region in order to maximize the power output in two different scenarios: For a fixed number ...
  • Patwary, Mostofa Ali (Doctoral thesis, The University of Bergen, 2011-08-26)
  • Abyaneh, Mohammad Reza Sohizadeh (Conference object, The author, 2012)
    Recently, Alomair et al. proposed the first Un- Conditionally Secure mutual authentication protocol for lowcost RFID systems(UCS-RFID). The security of the UCSRFID relies on five dynamic secret keys which are updated at ...
  • Schilling, Thorsten Ernst; Zajac, Pavol (Peer reviewed; Chapter, Versita Open, 2012)
    Many problems, including algebraic cryptanalysis, can be transformed to a problem of solving a (large) system of sparse Boolean equations. In this article we study 2 algorithms that can be used to remove some redundancy ...
  • El Ghami, Mohamed; Ivanov, I.D.; Roos, C.; Steihaug, Trond (Peer reviewed; Journal article, Academic Publications, 2008)
  • Brazma, Alvis; Jonassen, Inge; Vilo, Jaak; Ukkonen, Esko (Journal article, Cold Spring Harbor Laboratory Press, 1998-05-18)
    We performed a systematic analysis of gene upstream regions in the yeast genome for occurrences of regular expression-type patterns with the goal of identifying potential regulatory elements. To achieve this goal, we have ...
  • Hollup, Siv Midtun (Doctoral thesis, The University of Bergen, 2010-04-19)
    This thesis, which contains an introduction and four manuscripts, summarises my efforts during my the past four years to understand proteins, their structure and dynamics. The first manuscript presents a protocol that ...
