      The formalism of complex rotation of the radial coordinate is studied in the context of time-dependent systems. The applicability of this method is discussed and illustrated with numerical examples involving atoms exposed ...
    • If I had a rich picture… : insights into the use of “soft” methodological tools to support the development of interprofessional education 

      Fougner, Marit; Habib, Laurence (Informa Healthcare, 2008)
      This paper describes a methodological experiment that aimed to test a small number of tools borrowed from Soft Systems Methodology. Those tools were intended to support action research for a project in interprofessional ...
    • Solution of the Dirac equation for hydrogenlike systems exposed to intense electromagnetic pulses 

      Selstø, Sølve; Bengtsson, Jakob; Lindroth, Eva (2009)
      The time-dependent Dirac equation is solved numerically and compared to the corresponding prediction of the nonrelativistic Schrödinger equation for hydrogenlike systems exposed to intense laser pulses. It is found that ...
    • The structure behind it all 

      Lindroth, Eva; Argenti, Luca; Bengtsson, Jakob; Ferro, Fabrizio; Genkin, Michael; Selstø, Sølve (IOP Publishing, 2009)
      The talk discussed collisions where the structure of the systems involved plays a decisive role for the outcome of the event. For many types of charge changing processes the presence of resonant states can change the ...
    • Ideals generated by submaximal minors 

      Kleppe, Jan Oddvar; Miro-Roig, Rosa Maria (Mathematical Science Publishers, 2009)
      The goal of this paper is to study irreducible families W(b;a) of codimension 4, arithmetically Gorenstein schemes X of P^n defined by the submaximal minors of a t x t matrix A whose entries are homogeneous forms of degree ...
    • Branded selves : how children in Norway relate to marketing on a social network site 

      Skaar, Håvard (Taylor & Francis, 2009-07-22)
      Theories of branding and self presentation inform an ethnographic study of how a group of classmates aged 11–12 construct identities by use of the brands and branded resources made available to them on the social network ...
    • Towards calibration-free geo-localization of stationary outdoor webcams 

      Sandnes, Frode Eika (Tapir Akademisk Forlag, 2010)
      This study proposes two strategies for determining the approximate geographical location of outdoor webcams based on time-series comprising regularly sampled images. The strategies require an accurate account of universal ...
    • Near Eyes-Free Chauffeur Computer Interaction with Chording and Visual Text Mnemonics 

      Sandnes, Frode Eika; Huang, Yo-Ping; Huang, Yueh-Min (Graz University of Technology, Institut für Informationssysteme und Computer Medien (IICM), 2010)
      Modern cars are equipped with advanced technology requiring cognitively complex operation that is reliant on the user’s visual attention. It is therefore hazardous for drivers to operate such devices while driving. In ...
    • Effects of common keyboard layouts on physical effort : implications for kiosks and Internet banking 

      Sandnes, Frode Eika (Tapir akademiske forlag, 2010)
      This study investigates the effect common keyboard layouts have physical effort. First, alphabetic keyboard layouts are experimentally compared to the QWERTY layout. Second, the number row often found on QWERTY keyboards ...
    • On the relativity of rotation 

      Grøn, Øyvind (Italian Physical Society, 2010)
      The question whether rotational motion is relative according to the general theory of relativity is discussed. Einstein’s ambivalence concerning this question is pointed out. In the present article I defend Einstein’s way ...
