    • APRS sporing og den frivillige redningstjenesten 

      Hanssen, Øyvind (Conference object; Konferansebidrag, 2011)

    • Creating and testing APRS (Automatic Position Reporting System) - technology for GPS tracking and messaging (via radio and internet) in areas without infrastructure 

      Hanssen, Øyvind (Conference object; Konferansebidrag, 2010-01-28)

    • A Declarative Profile Model for Qos negotiation 

      Hanssen, Øyvind (Research report; Forskningsrapport, 2005-12)
      In this report we define the semantics of a language for dynamic QoS expressions which can be evaluated at run-time for conformance. We define how expressions can be constructed from atomic expressions termed ’basic profiles’ using composition operators. Two such operators are defined: The sum ( ’+’ ) which corresponds to simple conjunction and component-sum (’Å’) which assume that the operands ...

    • FlexiNet - QoS Investigation 

      Hanssen, Øyvind (Research report; Forskningsrapport, 1997)
      In this report we investigate what are the main concepts and issues in the support of Quality of Service, focusing at open distributed computing and middleware platforms. We study how these issues are being addressed in research on QoS support related to middleware. QoS is about non-functional properties in general, but research has been centred around communication protocols and multimedia. The ...

    • Objekt-adapter og programmeringsgrensesnitt for ANSAware applikasjoner 

      Hanssen, Øyvind (Master thesis; Mastergradsoppgave, 1994)
      I denne hovedfagsavhandlinga undersøkes avbildningsmekanismer mellom ANSAware applikasjoner og en føderativ omgivelse. Dette gjøres innefor rammen av ODS-gruppas arbeid med samvirkende informasjonssystemer. For å få kunnskap om problemområdet og om hvordan avbildning effektivt kan utføres, utvikles et rammeverk for modellering, design og implementasjon av avbildningsmekanismer. Vi fokuserer spesielt ...

    • On the design of a generic object adaptor 

      Eliassen, Frank; Hanssen, Øyvind (Conference object; Konferansebidrag, 1995-08)

    • Quality of service aware binding in open systems 

      Hanssen, Øyvind (Doctoral thesis; Doktorgradsavhandling, 2008-02-07)
      This thesis addresses negotiation of bindings in QoS aware open systems and in particular how to characterize possible contracts, requirements and capabilities of heterogeneous environments. Our approach is (1) to use trading of policies as the principle for negotiation and (2) the use of declared or rule-based conformance for QoS statements to be used in negotiation and (3) a middleware binding ...

    • Secure Distributed Storage in Peer to Peer Networks 

      Hanssen, Øyvind (Lecture; Forelesning; Peer reviewed, 2008-02-07)

    • Towards Declarative Characterisation and Negotiation of Bindings 

      Hanssen, Øyvind (Chapter; Bokkapittel, 2005-12)

    • Towards the Semantic Desktop 

      Hanssen, Øyvind (Conference object; Konferansebidrag, 2010-04)
      In this presentation we describe some key aspects of the social semantic desktop vision, the main results of research by computer scientists in this area so far. We discuss how this may change the way people manage and share their information, and we discuss how this may change the role of academic librarians. <br>The trends seem to point towards that computers will be more personal and personalised. ...
