    • Hvordan skal norske kommuner tilpasses et klima i endring? 

      Granum, Gina (Master thesis; Mastergradsoppgave, 2022-06-01)
      Norge har forpliktet seg til Parisavtalen og FNs 17 bærekraftsmål. Dette inkluderer blant annet en forpliktelse til at landet skal klimatilpasses og blant Norges nasjonale miljømål finner en et politisk mål som stadfester dette. I forbindelse med miljødirektoratets presentasjon av Norges miljømål hevdes det at dersom samfunnet mislykkes i å tilpasses klimaendringene kan sårbarheten for endringene ...

      Large national programs in the United States and several Asian countries have defined and characterised their marine methane hydrate occurrences in some detail, but European hydrate occurrence has received less attention. The European Union-funded project “Marine gas hydrate – an indigenous resource of natural gas for Europe” (MIGRATE) aimed to determine the European potential inventory of exploitable ...
    • Hydration dynamics and the future of small-amplitude afm imaging in air 

      Santos Hernandez, Sergio; Olukan, Tuza Adeyemi; Lai, Chia-Yun; Chiesa, Matteo (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-23)
      Here, we discuss the effects that the dynamics of the hydration layer and other variables, such as the tip radius, have on the availability of imaging regimes in dynamic AFM—including multifrequency AFM. Since small amplitudes are required for high-resolution imaging, we focus on these cases. It is possible to fully immerse a sharp tip under the hydration layer and image with amplitudes similar to ...
    • Hydrocarbon leakage driven by quaternary glaciations in the Barents Sea based on 2D basin and petroleum system modeling 

      Kishankov, Aleksei; Serov, Pavel; Bünz, Stefan; Patton, Henry Jared; Hubbard, Alun Lloyd; Mattingsdal, Rune; Vadakkepuliyambatta, Sunil; Andreassen, Karin Marie (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-25)
      The Barents Sea has experienced intense erosion throughout the Cenozoic due to uplift and repeated episodes of glaciation. This, in turn, has driven large pressure and temperature fluctuations in the sediment substrate along with rearrangement of thermogenic oil and gas accumulations. As a result, some hydrocarbon fields have relatively shallow depths, and natural gas release is widespread. This ...

      Njone, Isaac (Master thesis; Mastergradsoppgave, 2014-11-21)
      The 3D seismic enable a better understanding of phreatomagmatic activity that occurred at the Gjallar ridge in the Vøring basin, mid-Norway. Structures associated with this activity were imaged and a causality relationship was established. Those structures included hydrothermal vent complexes, sill complexes and faults. The Kai formation significantly affected by polygonal faulting that were likely ...
    • Hyperbolic cone metrics and billiards 

      Erlandsson, Viveka; Leininger, Christopher J.; Sadanand, Chandrika (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-31)
      A negatively curved hyperbolic cone metric is called rigid if it is determined (up to isotopy) by the support of its Liouville current, and flexible otherwise. We provide a complete characterization of rigidity and flexibility, prove that rigidity is a generic property, and parameterize the associated deformation space for any flexible metric. As an application, we parameterize the space of ...
    • HyperKvasir, a comprehensive multi-class image and video dataset for gastrointestinal endoscopy 

      Borgli, Hanna; Thambawita, Vajira; Smedsrud, Pia H; Hicks, Steven; Jha, Debesh; Eskeland, Sigrun Losada; Randel, Kristin Ranheim; Pogorelov, Konstantin; Lux, Mathias; Dang Nguyen, Duc Tien; Johansen, Dag; Griwodz, Carsten; Stensland, Håkon Kvale; Garcia-Ceja, Enrique; Schmidt, Peter T; Hammer, Hugo Lewi; Riegler, Michael; Halvorsen, Pål; de Lange, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-28)
      Artificial intelligence is currently a hot topic in medicine. However, medical data is often sparse and hard to obtain due to legal restrictions and lack of medical personnel for the cumbersome and tedious process to manually label training data. These constraints make it difficult to develop systems for automatic analysis, like detecting disease or other lesions. In this respect, this article ...
    • The Hyperporphyrin Concept: A Contemporary Perspective 

      Wamser, Carl C.; Ghosh, Abhik (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-30)
      The Gouterman four-orbital model conceptualizes porphyrin UV−visible spectra as dominated by four frontier molecular orbitals-two nearly degenerate HOMOs and two exactly degenerate LUMOS under D<sub>4h</sub> symmetry. These are well separated from all the other molecular orbitals, and normal spectra involve transitions among these MOs. Unusual spectra occur when additional orbitals appear in ...
