      A future sustainable energy system is expected to be digital, de-central, de-carbonized, and democratized. As the transition unfolds, new and diverse actors of various sizes will emerge in different segments. Thereby, the future energy system could shift its attention to the actors’ behavior than finding an optimum based on the physical system. Agent based modeling tools can reflect decisions from ...

    • Numerical simulations of coherent blob-like filaments in magnetized plasmas 

      Antonsen, Daniel Elisabethsønn (Mastergradsoppgave; Master thesis, 2024-12-16)
      In a world more and more dependent on new and effective energy sources, the introduction of fusion power could prove invaluable. Magnetic confinement of plasma has proved to be difficult, and the curvature of the magnetic field lines in tokamaks give rise to charge polarization at the boundary of the fusion devices leading to cross-field transport. Experiments has shown that the dominating transport ...
    • Introducing Glycemic Index to Blood Glucose Simulations and its effect on Food Recommendation Systems 

      Buholdt, Håvard Strid (Mastergradsoppgave; Master thesis, 2024-12-02)
      The availability of In-Silco blood glucose simulators that accurately depict all aspects of Diabetes Mellitus patient’s daily life is crucial for the development of safe and effective new treatment technologies. Current state of the art simulators focus on modeling a meal’s effect on the glucose-insulin system solely based on the quantity of carbohydrates consumed. However not only the quantity of ...
    • Giant pit craters on the modern seafloor above magma-induced hydrothermal vent complexes of Scotia Sea, offshore Antarctica 

      Somoza, L.; Andreassen, Karin Marie; Plaza-Faverola, Andreia; Medialdea, T.; Gafeira, J.; González, F. J.; Dickens, G. R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2025-01-24)
      Massive injection of <sup>13</sup>C depleted carbon to the ocean and atmosphere coincided with major environmental upheaval multiple times in the geological record. For several events, the source of carbon has been attributed to explosive venting of gas produced when magmatic sills intruded organic-rich sediment. The concept mostly derives from studies of a few ancient sedimentary basins with numerous ...

      Borealis is a recently discovered submerged mud volcano in the Polar North Atlantic, differing from the numerous methane seepages previously identified in the region. Here we show in situ observations from a remotely operated vehicle (ROV), capturing the release of warm (11.5 °C) Neogene sediments and methane-rich fluids from a gryphon at Borealis. The surrounding seafloor within the mud volcano ...
    • Enhancing assessment of direct and indirect exposure of settlement-transportation systems to mass movements by intergraph representation learning 

      Dimasaka, Joshua; Selvakumaran, Sivasakthy; Marinoni, Andrea (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-14)
      Amidst the intensifying extreme rainfall patterns due to climate change, global early warning systems for mass movements (e.g. landslides, avalanches) need to provide not only the coarsely aggregated danger reports, but also the necessary fine details to understand its potential implications on critical infrastructures such as transportation systems. In this study, we introduce a novel ‘intergraph’ ...
    • Measuring societal safety: An analysis of societal safety-related composite indices and their alignment with the Norwegian understanding of societal safety 

      Dahl, Joakim Broks (Master thesis; Mastergradsoppgave, 2024-11-23)
      The global society is shaped by the continous emerge of new technologies and increased globalization which makes the world more interconnected. This affects the ways in which risks can impact, and alters the global state of societal safety. The effects of climate induced events and conflicts can have impacts sporadically, and one must therefore adapt to the new risk pathways. By analyzing societal ...

      The youngest volcanic event known from Svalbard is represented by the Bockfjorden Volcanic Complex, located northwest on Spitsbergen at the passive continental margin. Mantle-derived xenoliths from Bockfjorden Volcanic Complex provide petrological insight to the mantle conditions beneath Svalbard, the northwestern extremity of the Eurasian lithospheric plate. New methods are available for pressure ...
    • Rhenium-Sulfido and -Dithiolato Corroles: Reflections on Chalcophilicity 

      Alemayehu, Abraham; Settineri, Nicholas S.; Lanza, Arianna E.; Ghosh, Abhik (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-16)
      he high-temperature (∼180 °C) reaction between free-base mesotriarylcorroles and Re<sub>2</sub>(CO)<sub>10</sub>, followed by exposure to PCl3 and thiols (or elemental sulfur), affords rhenium-sulfido (ReS) corroles in 67−76% yields. The use of shorter reaction times, lower temperatures (∼130 °C), and a dithiol (e.g., ethane-1,2-dithiol) also allows the isolation of rhenium-dithiolato corroles, ...

      We estimate sea-ice type specific incidence angle (IA) dependencies for dual polarized (HH/HV) L and C-band synthetic aperture radar (SAR) for the winter, melt onset and advanced melt seasons for level and deformed ice, using time-series of Advanced Land Observing Satellite-2 (ALOS-2) and Sentinel-1 imagery off the north-east coast of Greenland. The IA dependencies are used to radiometrically ...

      Land surface temperature (LST) serves as an important climate variable which is relevant to a number of studies related to energy and water exchanges, vegetation growth and urban heat island effects. Although LST can be derived from satellite observations, these approaches rely on cloud‐free acquisitions. This represents a significant obstacle in regions which are prone to cloud cover. In this ...

The primary objective of this initiative is to create a system that can adapt dynamically to varying contexts by understanding and acting upon the intents of stakeholders in a decentralised and strategic manner. ...
    • Spin representations and binary numbers 

      Winther, Henrik (Journal article; Tidsskriftartikkel; Peer reviewed, 2024)
      We consider a construction of the fundamental spin representations of the simple Lie algebras so(n) in terms of binary arithmetic of fixed width integers. This gives the spin matrices as a Lie subalgebra of a Z-graded associative algebra (rather than the usual N-filtered Clifford algebra). Our description gives a quick way to write down the spin matrices, and gives a way to encode some extra structure, ...
