    • Formulae for partial widths derived from the Lindblad equation 

      Selstø, Sølve (American Physical Society, 2012-06-28)
      A method for calculating partial widths of autoionizing states is proposed. It combines either a complex absorbing potential or exterior complex scaling with the Lindblad equation. The corresponding classical rate equations ...
    • A framework for evaluating continuous microservice delivery strategies 

      Lehmann, Martin; Sandnes, Frode Eika (Association for Computing Machinery (ACM), 2017)
      The emergence of service-oriented computing, and in particular microservice architecture, has introduced a new layer of complexity to the already challenging task of continuously delivering changes to the end users. Cloud ...
    • From a career development programme to professional doctorate or practice-oriented PhD : a Norwegian case study 

      Bjørke, Gerd; Habib, Laurence (Middlesex University, 2011-10)
      This article describes a career development programme in Norway, which might be compared to the Professional Doctorate programmes worldwide. This particular programme supports teachers who intend to apply for ‘alternative’ ...
    • From alien to domestic? : virtual learning environment use from a domestication perpective

      This article proposes to use the concept of domestication as an analytic tool to understand patterns of use of a Virtual Learning Environment (VLE) and user attitudes towards VLEs. The data gathered includes ...
    • A Fuzzy ART2 Model for Finding Association Rules in Medical Data 

      Huang, Yo-Ping; Vu, Thi Thanh Hoa; Jau, Jung-Shian; Sandnes, Frode Eika (IEEE Computer Society, 2010-09)
      This paper describes a model that discovers association rules from a medical database to help doctors treat and diagnose a group of patients who show similar prehistoric medical symptoms. The proposed data mining ...
    • Fuzzy Environment Mapping for Robot Navigation Based on Grid Computing 

      Kao, Li-Jen; Huang, Yo-Ping; Sandnes, Frode Eika; Hsiao, Mann-Jung (IEEE Press, 2010)
      In order to navigate autonomously, a mobile robot needs to build an environment map where the robot is navigating. Currently, the sensors are mounted on the robot to detect if the obstacles exist and then the map immediate ...
    • A General Formalism for Defining and Detecting OpenFlow Rule Anomalies 

      Aryan, Ramtin; Yazidi, Anis; Engelstad, Paal E.; Kure, Øivind (IEEE, 2017)
      SDN network's policies are updated dynamically at a high pace. As a result, conflicts between policies are prone to occur. Due to the large number of switches and heterogeneous policies within a typical SDN network, detecting ...
    • General TCP state inference model from passive measurements using machine learning techniques
