    • Vurdering av skriftlige elevbesvarelser i matematikk 

      Jakobsen, Jakob Berglund (Master thesis, 2025)
      Ifølge læreplanene i matematikk skal underveisvurderingen «bidra til å fremme læring og til å utvikle kompetanse i matematikk» (Utdanningsdirektoratet, 2020). All vurdering som ikke er summativ skal brukes til å fremme og øke elevens kompetanse (Engh & Gran, 2021). Med dette i bakhodet og at vurdering i seg selv er komplekst, ønsket jeg å undersøke hvordan lærere begrunner sine vurderinger av ...

    • Bayesian framework for curve alignment and change point detection applied to marine sediment core data 

      Knudsen, Jørgen (Master thesis, 2025)
      Paleoclimate proxy records such as marine sediment cores are crucial for understanding past climate conditions. The deposition rate for these archives may vary dramatically both within individual cores and between them, obfuscating the temporal expression of events. Accurate alignment of cores is therefore critical for determining extent and rate of past climate change. Current methods are performed ...
    • Modelling ice throw trajectories from wind turbines 

      Hjallar, Milla Regine Antonsen (Master thesis, 2025)
      Wind turbines in cold climates can occasionally experience ice throws that travel significant distances, posing a low-probability but high-consequence safety risk. Current guidelines typically rely on the empirical Seifert safety distance, defined as d = k x (H + D), where k is the throw factor – commonly set to 1.5, H is the hub height, and D is the rotor diameter. However, both observational field ...
