Terrorforebygging gjennom arealplanlegging
(Master thesis, 2023)Terrorangrepet i Regjeringskvartalet og på Utøya 22. juli i 2011, samt andre terrorangrep i vestlige byer som Paris, Nice, Barcelona, Brussel, London og Stockholm i 2016 og 2017, har ført til store diskusjoner om sikring ... -
Design basis considerations for the design of floating offshore wind turbines
(Peer reviewed; Journal article, 2023)The wind farm owner/operator must prepare a Design Basis to facilitate the design of floating offshore wind turbines. The Design Basis is crucial to ensure that the individual elements of the wind farm are designed according ... -
Cavity Size Effects on the Adsorption of CO2 on Pillar[n]arene Structures: A Density Functional Theory Study
(Peer reviewed; Journal article, 2023-08)Carbon dioxide (CO2) is the main greenhouse gas that contributes to the global warming. Therefore, CO2 adsorption is very urgent in the fight to limit global warming below 1.5 degrees Celsius. In this report, the interaction ... -
Growth Opportunities for an Alpine Ski Resort in Norway
(Peer reviewed; Journal article, 2023)This paper explores growth opportunities for an Alpine ski resort in Norway, examining potential investments in infrastructure, market expansion, and diversification of services. The financial implications of capital ... -

Radiofrequency Interference Strategies Targeting Marine Navigation Systems: Political Motives and Consequences
(Peer reviewed; Journal article, 2023-06)Maritime traffic from the Baltic Sea and Black Sea to the Strait of Hormuz has experienced frequent and prolonged instances of radiofrequency interference which has been attributed to military exercises, anti-drone defence, ... -
Simulation and Prediction of Countercurrent Spontaneous Imbibition at Early and Late Time Using Physics-Informed Neural Networks
(Peer reviewed; Journal article, 2023-09)The application of physics-informed neural networks (PINNs) is investigated for the first time in solving the one-dimensional countercurrent spontaneous imbibition (COUCSI) problem at both early and late time (i.e., before ... -
On the three-dimensional effects of the water entry of wedges
(Peer reviewed; Journal article, 2023-09)Three-dimensional (3D) effects on the total and spanwise slamming coefficients and the pressure reductions acting on the wedge surface during water entry are modeled in a unified manner. First, the water entry of wedges ... -
Coherent feedback leads to robust background compensation in oscillatory and non-oscillatory homeostats
(Peer reviewed; Journal article, 2023-08)When in a reaction kinetic integral controller a step perturbation is applied besides a constant background, the concentration of a controlled variable (described as A) will generally respond with decreased response ... -
Risk literacy : Foundational issues and its connection to risk science
(Peer reviewed; Journal article, 2023-09)A new research area is developing, risk literacy. The term “risk literacy” basically refers to one's ability to understand and evaluate risk, in order to support and make appropriate decisions. In this article, we discuss ... -
Autonomous Trajectory Design Considering the Limitation of Torque and Drag Forces
(Master thesis, 2023)In the oil and gas industry, designing well trajectories is an important part of drilling operations that affect well construction, completion, and production. But the current trajectory planning process works in isolation ... -
Investigation of the enantioselectivity of acetylcholinesterase and butyrylcholinesterase upon inhibition by tacrine-iminosugar heterodimers
(Peer reviewed; Journal article, 2023-09)The copper-catalysed azide-alkyne cycloaddition was applied to prepare three enantiomeric pairs of heterodimers containing a tacrine residue and a 1,4-dideoxy-1,4-imino-D-arabinitol (DAB) or 1,4-dideoxy-1,4-imino-L-arabinitol ... -
Coping with different system logics of standardization in regulatory regimes. Norwegian offshore experience
