    • The application of unmanned aerial vehicles for snow avalanche search and rescue 

      Albrigtsen, Andreas (Master thesis; Mastergradsoppgave, 2016-06-01)
      Snow avalanches claim in excess of 200 lives annually on a worldwide basis. However, since the invention of the first effective avalanche transceiver, the process of locating victims has remained fundamentally unchanged. Humans as a carrier for locating devices are perceived to be inefficient when moving over rugged avalanche debris, and potentially exposed to excessive risk from secondary avalanches. ...

      Waste incineration-based district heating plants in Norway struggle from energy efficiency drawbacks during the warmer months of the year from May - September due to the reduced demand in heating. As a result, thermal energy gets discarded to ambient air, which affects the energy efficiency of the plants. This study aims at presenting an overview of the waste incineration industry in Norway and ...
    • Finite element analysis of materials for aquaculture net cages. FEA of materials for aquaculture net cages using ANSYS Workbench 

      Myrli, Odd Einar Lockertsen (Master thesis; Mastergradsoppgave, 2017-06-20)
      The number of good sites in less exposed locations for aquaculture farming is limited. Trends are now that the fish cages are increasing in both width and depth as well as more weather-exposed locations are taken into use. As the net cages continues to increase in size, so does the material costs. The design of the sea cages should be modified for safe and reliable use in remote offshore locations. ...
