Comparison of 3D and 2D rockfall models. Considering terrain model quality effect on respective model performances
(Master thesis; Mastergradsoppgave, 2018-05-15)Rockfalls are blocks of rock that bounce and roll down slopes. They are commonly detached from rock-slopes with inclinations over 40-45°. They embody high energy and mobility and are a major cause of landslide related deaths. Rockfalls can be simulated using empirical relationships and modelling, of which 2D and 3D variants exist for the latter. 3D models allow for rock fragment- and surface shape ... -
Metadata state and history service for datasets. Enable extracting, storing and access to metadata about a dataset over time.
(Master thesis; Mastergradsoppgave, 2018-05-14)Distributed Arctic Observatory (DAO) aims to automate, streamline and improve the collection, storage and analysis of images, video and weather measurements taken on the arctic tundra. Automating the process means that there are no human users that needs to be involved in the process. This leads to a loss of monitoring capabilities of the process. There are insufficient tools that allow the human ... -

Reconstructing the retreat dynamics of the Bjørnøyrenna Ice Stream based on new 3D seismic data from the central Barents Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-01)The stability of contemporary ice sheets is influenced by the discharge from ice streams - corridors of fast-flowing ice bounded by ice flowing an order of magnitude slower. Reconstructions of palaeo-ice stream dynamics contribute to our understanding of ice stream sensitivity to the ocean-climate system and can aid in the numerical modelling and prediction of future changes in contemporary ice ... -
Glacial isostatic adjustment associated with the Barents Sea ice sheet: A modelling inter-comparison
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-01)The 3D geometrical evolution of the Barents Sea Ice Sheet (BSIS), particularly during its late-glacial retreat phase, remains largely ambiguous due to the paucity of direct marine- and terrestrial-based evidence constraining its horizontal and vertical extent and chronology. One way of validating the numerous BSIS reconstructions previously proposed is to collate and apply them under a wide range ... -
Conformal differential invariants
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-27)We compute the Hilbert polynomial and the Poincar´e function counting the number of fixed jet-order differential invariants of conformal metric structures modulo local diffeomorphisms, and we describe the field of rational differential invariants separating generic orbits of the diffeomorphism pseudogroup action. This resolves the local recognition problem for conformal structures. -
Atmospheric circulation patterns associated with avalanche cycles in the Troms region
(Master thesis; Mastergradsoppgave, 2018-05-15)Snow avalanches endangers human lives and infrastructure situated in alpine environments during the winter season.
