    • Skredsøk ved bruk av magnetometer 

      Iwe, Harald (Research report, 2003)
      En innledende teoretisk analyse viser at den beste metoden for å detektere begravde ferromagnetiske gjenstander er ved å bruke to magnetometre montert i en fast avstand og å bruke forskjellen i måleverdi (gradienten) som ...

    • The SLAB test - The missing link in stability testing? 

      Brattlien, Kjetil; Ellevold, Jo Gunnar (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2010)
      An avalanche is released when both the weak layer and the slab fails, still standard stability tests (e.g. CT, ECT) focus on the weak layer only. The SLAB test gives information on both the weak layer and the slab, hence ...
    • Slush-flow questionnaire.
