    • Connecting the dots in counterterrorism: The consequences of communication setting for shared situation awareness and team performance 

      Valaker, Sigmund; Hærem, Thorvald; Bakken, Bjørn T. (2018)
      Shared situation awareness (SSA) is critical for counterterrorism teams. We examined whether a rich media condition (co‐located face to face) and a lean media condition (distributed email) differentially influence SSA at ...
    • Improved correction methods for measuring altitude by Radar and Barometer 

      Åsen, Walther (2018)
      Geometric altitude of air targets may be found from radar or barometric measurement. However, radar rays are affected by changes in refractive index gradients which result in non-normal bending of rays. Similarly, precision ...
    • Guidelines for using animal models in blast injury research 

      Watts, Sarah; Kirkman, Emrys; Bieler, Dan; Bjarnason, Stephen; Franke, Axel; Gupta, Raj Kumari; Leggieri, Michael J.; Orru, Hans; Ouellet, Simon; Philippens, Mat M. G. M.; Sarron, Jean-Claude; Skriudalen, Stian; Teland, Jan Arild; Risling, Mårten; Cernak, Ibolja (2018)
      Blast injury is a very complex phenomenon and frequently results in multiple injuries. One method to investigate the consequences of blast injuries is with the use of living systems (animal models). The use of animals ...
    • A 3D Reactive Collision Avoidance Algorithm for Underactuated Vehicles 

      Syre Wiig, Martin; Pettersen, Kristin Ytterstad; Krogstad, Thomas Røbekk (2018)
      This paper presents a 3D reactive collision avoidance algorithm for vehicles with underactuated dynamics. The underactuated states cannot be directly controlled, but are controlled indirectly by steering the direction of ...
    • Image-aided inertial navigation for an Octocopter 

      Sivalingam, Baheerathan; Hagen, Ove Kent (2018)
      A typical unmanned aerial system combines an Inertial Navigation System (INS) and a Global Navigation Satellite System (GNSS) for navigation. When the GNSS signal is unavailable, the INS errors grow over time and eventually ...
    • Correlation between sediment properties and seafloor characterization maps based on multibeam backscatter data from three regions off the coast of Norway 

      Eidem, Ellen Johanne (2017)
      Multibeam echo sounder data from Kongsberg EM 1002 and EM 710 (70– 100 kHz) acquired between 2003 and 2014 were processed using QPS Fledermaus Geocoder Toolbox (FMGT) to produce backscatter mosaics and maps of estimated ...
    • Supporting artificial intelligence with artificial images 

      Aurdal, Lars; Brattli, Alvin Andreas; Glimsdal, Eirik; Klausen, Runhild Aae; Løkken, Kristin Hammarstrøm; Palm, Hans Christian (2018)
      Infrared (IR) imagery is frequently used in security/surveillance and military image processing applications. In this article we will consider the problem of outlining military naval vessels in such images. Obtaining these ...
    • A 3D Reactive Collision Avoidance Algorithm for Nonholonomic Vehicles 

      Syre Wiig, Martin; Pettersen, Kristin Ytterstad; Krogstad, Thomas Røbekk (2018)
      This paper presents a 3D reactive collision avoidance algorithm for vehicles with nonholonomic constraints. The algorithm steers the heading and pitch angle of the vehicle in order to maintain a constant avoidance angle ...
    • An Integral Line-of-Sight Guidance Law with a Speed-dependent Lookahead Distance 

      Syre Wiig, Martin; Pettersen, Kristin Ytterstad; Ruud, Else-Line Malene; Krogstad, Thomas Røbekk (2018)
      This paper presents an algorithm that makes an underactuated marine vehicle follow a straight line path while in the presence of a constant ocean current. When following the path, the vehicle maintains a desired surge speed ...
    • Automating Event-B invariant proofs by rippling and proof patching 

      Lin, Yuhui; Bundy, Alan; Grov, Gudmund; Maclean, Ewen (2019-01-02)
      The use of formal method techniques can contribute to the production of more reliable and dependable systems. However, a common bottleneck for industrial adoption of such techniques is the needs for interactive proofs. We ...
    • Terrain referenced navigation using sand dunes and sand ripples in presence of tides 

      Hagen, Ove Kent; Ånonsen, Kjetil Bergh (2018)
