      This brief report aims to present right of self-defence against terrorist groups, e.g. in a situation where terrorist groups are based on the territory of a collapsed state. The scope of the report is limited to the main ...

    • VoluViz 1.0 report 

      Helgeland, Anders; Gaarder, Trond (2002)
      VoluViz is a direct volume rendering application based on SGI's OpenGL Volumizer 2 and OpenGL, and is designed for interactive viewing of three-dimensional volume data. Its features include trilinear interpolation, ...

    • Effectiveness of forces and C2 in a semi-chaotic environment - an integrating methodology 

      Sundfør, Hans Olav (2001)
      The effect of C2 on force effectiveness is given substantial attention over the last decades. However, analysts are still struggling to reflect this effect. This report presents a methodology that reflects the contribution ...

    • Penetration into concrete - analysis of small scale experiments with 12 mm projectiles 

      Sjøl, Henrik; Teland, Jan Arild; Kaldheim, Øyvind (2002)
      The analytical approach for predicting penetration of rigid projectiles into concrete targets indicates that the scaled penetration depth is a function of only two non-dimensional parameters. This report analyses experiments ...

    • Range localication of 10-100 km shots by means of an endfire array and a waveguide invariant 

      Søstrand, Knut A. (2002)
      During a shallow-water acoustic experiment, signals from small explosions were recorded on an endfire horizontal array. The experiment took place in open waters with relatively slow changes of the water depth with range. ...

    • The joint NO and UK demonstration of integrated MMHS, PKI and Directory Systems at JWID 2003
