      Gjøsteen, Kristian (Doktoravhandlinger ved NTNU, 1503-8181; 2004:69, Doctoral thesis, 2004)
      Public key encryption was first proposed by Diffie and Hellman [16], and widely popularised with the RSA cryptosystem [37]. Over the years, the security goals of public key encryption have been studied [17, 22], as have ...
    • Suggested Methods for Preventing Core Saturation Instability in HVDC Transmission Systems 

      Norheim, Ian (Dr. ingeniøravhandling, 0809-103X; 2002:15, Doctoral thesis, 2002)
      In this thesis a study of the HVDC related phenomenon core saturation instability and methods to prevent this phenomenon is performed. It is reason to believe that this phenomenon caused disconnection of the Skagerrak HVDC ...
    • Supporting Relationships in Digital Libraries 

      Aalberg, Trond (Doctoral thesis, 2003)
      The motivation for this work is based on two recognized research issues for digital libraries. One is the need for interlinked and semantically rich information spaces where relationship information is of particular ...
    • Svake høyfrekvente elektromagnetiske felt - en vurdering av helserisiko og forvaltningspraksis
