    • An Energy Balance Model on an Infinite Line 

      Elvevold, Ask (Master thesis; Mastergradsoppgave, 2022-06-01)
      The thesis is an expansion of the work Gerald R. North did in 1975 on an energy balance climate model. By considering a similar model on an infinite line, and allowing the heat diffusion coefficient to vary on the line, more complicated behaviour arose from the model. Much of Norths work was recreated on the infinite lines, but a lot of new discoveries were made. Among what was found were spontaneous ...

    • The role of avalanche education in assessing and judging avalanche risk factors 

      Landrø, Markus; Engeset, Rune Verpe; Pfuhl, Gerit (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-07)
      Avalanche decision-making falls into two general categories; probabilistic approaches and analytical approaches. Analytical approaches have traditionally been considered applicable to experts only, as they require assessing risk factors precisely and understanding their relevance in each situation. In this study we question this assumption. We asked 1,220 amateur backcountry recreationalists how ...
