      Biologisk eller kjemisk terror, der biologiske eller kjemiske stoffer benyttes for å skade eller ta livet av sivile, er en trussel med store potensielle konsekvenser. Flere kjemiske og biologiske trusselstoffer kan være ...
    • A computational study of density of some high energy molecules 

      Moxnes, John Fredrik; Hansen, Finn Knut; Jensen, Tomas Lunde; Sele, Marta Lill; Unneberg, Erik (2016)
      The detonation pressure depends quadratically on the loading density of the explosives. A precise estimate of the density is thus crucial to decide if a novel energetic material is worth pursuing. In this work we investigate ...

      Korsnes, Reinert; Westrum, Karin; Fløistad, Erling; Klingen, Ingeborg (2016)
      This contribution demonstrates an example of experimental automatic image analysis to detect spores prepared on microscope slides derived from trapping. The application is to monitor aerial spore counts of the entomopathogenic ...
    • Computing turbulence structure tensors in plane channel flow 

      Vartdal, Magnus (2016)
      This paper is concerned with the computation of turbulence structure tensors in plane channel flow. It has been pointed out that the previously computed turbulence structure tensors, for this configuration, used an ...
    • A concept approach to input/output logic 

      Stolpe, Audun (2015)
      This paper provides a semantics for input/input output logic based on formal concept analysis. The central result shows that an input/output logic axiomatised by a relation R is the same as the logic induced by deriving ...
    • Concept for trusted binding of metadata to data 

      Gjertsen, Tor (2013-02-27)
      Information exchange is a critical part of military operations. Information flows between domains are traditionally managed by air gaps and manual review-and-release procedures. More efficient information flow mechanisms ...
    • Condensed Matter Nuclear Science - fiksjon eller virkelighet 

      Author::Hasvold, Jon Øistein (2018-06-05)
      Fleischman og Pons publiserte i 1989 varmeutvikling fra en ukjent reaksjon mellom deuteriumatomer i en palladiumelektrode ved elektrolyse av tungtvann med oppløsning av 0,1 M litium deuterid (LiOD). Varmeutviklingen var ...
    • 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 ...
    • A connectionless multicast protocol for MANETs 

      Thi Minh Do, Viet; Landmark, Lars; Kure, Øivind (2012)
      In this paper, the connectionless multicast routing MCOM (Multipoint relay Connectionless Multicast) is introduced for mobile Ad hoc networks. MCOM adapts over a wide ranges of density of group members. It appears as unicast ...
    • Conscription in the new Russian Army 

      Andresen, Rolf-Inge Vogt (2010)
      Russia is implementing the most comprehensive reforms of its Armed Forces since the 1920s – ”the Serdiukov reforms”. The aim of the modernisation is to make Russia better able to deal with current threats. Conscription ...
    • Consequence assessment of indoor dispersion of sarin-A hypothetical scenario 

      Endregard, Monica; Reif, Bjørn Anders Pettersson; Vik, Thomas; Busmundrud, Odd (2010)
      The objective of this study is to provide a hypothetical scenario of indoor dispersion of the highly toxic nerve agent sarin in a large building, which can be used as a starting point for discussion, planning, training and ...
