      In Porsgrunn, Norway, there was an explosion in an ammonia plant in July 1985. The accident was caused by a hydrogen leak inside a factory building, called N1. The result was a severe hydrogen-air explosion and jet fire, ...
    • Hydrogen safety in confined spaces 

      Lach, Agnieszka Weronika (Doctoral dissertations at the University of South-Eastern Norway;130, Doctoral thesis, 2022-09-02)
      Unwanted hydrogen releases in confined spaces can be significantly more dangerous compared to open-air scenarios. The transmission towards a zero-emission system results in a growth of hydrogen-driven vehicles which increases ...
    • Identification of signals describing pairwise interaction in plankton, bacteria and bacteriophage : a study of model, microcosm and lake 

      Sandvik, Gunnar (Doctoral theses at NTNU;2003:54, Doctoral thesis; Peer reviewed, 2003)
      This study concerns interaction between organisms. Such interactions are often studied through organism abundances over periods of time (time-series). Time-series reflect both internal (biological) and external (environmental) ...
    • An Image Processing Framework for High Speed Videos from Combustion and Gas Explosion Experiments 

      Maharjan, Samee (Doctoral dissertations at the University of South-Eastern Norway;83, Doctoral thesis, 2020-12-18)
      The method of high speed photography is used to visualize those phenomena which occur so fast that it is impossible to visualize by the normal human eyes. One of those phenomena is a shock wave propagation during gas ...
    • Image-based sizing techniques for fire water droplets
