Effects of management practices for using the SaaS system on performance of hospitality firms in Norway
(Peer reviewed; Journal article, 2023)The earlier literature either measured management practices in terms of the general management traits or did not account for the effects on firm performance. However, the transformation of the Enterprise Resource Planning ... -
Firewall black holes and echoes from an action principle
(Peer reviewed; Journal article, 2023)It is often said that there is no gravity theory based on local action principles giving rise to firewall black hole solutions. Additionally, Guo and Mathur [Int. J. Mod. Phys. D 31, 2242009 (2022).] have cast doubt on the ... -
Pore-scale Ostwald ripening of gas bubbles in the presence of oil and water in porous media
(Peer reviewed; Journal article, 2023)Hypothesis Ostwald ripening of gas bubbles is a spontaneous mass transfer process that can impact the storage volume of trapped gas in the subsurface. In homogeneous porous media with identical pores, bubbles evolve toward ... -
Homeostasis at different backgrounds: The roles of overlayed feedback structures in vertebrate photoadaptation
(Peer reviewed; Journal article, 2023)We have studied the resetting behavior of eight basic integral controller motifs with respect to different but constant backgrounds. We found that the controllers split symmetrically into two classes: one class, based on ... -
Directed laser deposition of super duplex stainless steel: Microstructure, texture evolution, and mechanical properties
(Peer reviewed; Journal article, 2023-04)Microstructure and texture evolution of directed-laser deposited super-duplex stainless-steel, in the as-received block, were characterized using light and electron microscopies and electron backscattered diffraction. ... -
Techno-economic assessment of hydrogen production from seawater
(Peer reviewed; Journal article, 2023)Population growth and the expansion of industries have increased energy demand and the use of fossil fuels as an energy source, resulting in release of greenhouse gases (GHG) and increased air pollution. Countries are ... -
Study of the long-finned pilot whale (Globicephala melas) bile content - An indicator of ocean health
(Peer reviewed; Journal article, 2023)Globicephala melas has been harvested in the Faroe Islands for centuries. Given the distances travelled by this species, tissue/body fluid samples represent unique matrices to be considered as an integration of environmental ... -
Station keeping of a subsea shuttle tanker system under extreme current during offloading
(Peer reviewed; Journal article, 2023)This paper presents the station keeping challenge of the subsea shuttle tanker (SST) design during underwater loading and offloading at a subsea well under an extreme current environment. The paper investigates the movement ... -
Analysis and Assessment of Onshore and Offshore Wind Turbines Failures
(Peer reviewed; Journal article, 2023)The rapidly increasing energy demand and the inevitable negative effects on the environment caused by fossil-fuelled energy production have made renewable energy technologies increasingly important and preferred among the ... -
Power Transmission and Control in Microturbines’ Electronics: A Review
(Peer reviewed; Journal article, 2023)When the shaft rotates in microturbines, the rotational movement is converted to electrical power. This is achieved through a permanent magnet synchronous machine (PMSM) housed on the shaft and the power electronics ... -
A comparison study of power performance and extreme load effects of large 10-MW offshore wind turbines
(Peer reviewed; Journal article, 2023)The utilisation of offshore wind turbines has rapidly increased in the last decade, which has resulted in a steady increase in wind turbine sizes. The global average offshore wind turbine size has increased from 1.5 MW to ... -
De farligste blant oss – en analyse av metodeapparatet for risikovurdering og risikostyring av forvaringsdømte
(Master thesis, 2023)Antall forvaringsinnsatte i Norge er doblet de siste ti årene, til tross for at tallet på nye forvaringsdommer per år viser en jevn trend. Dette betyr at det er vanskeligere å bli løslatt fra forvaring enn tidligere. ... -
Characterisation of extreme load responses of a 10-MW floating semi-submersible type wind turbine
(Peer reviewed; Journal article, 2023)The global average size of offshore wind turbines has increased steadily from 1.5 MW to 6 MW from 2000 to 2020. With this backdrop, the research community has recently looked at huge 10–15 MW class floating offshore wind ... -
Connecting analysis, algebra, and topology; Generalizing Maxwell's equations
(Bachelor thesis, 2023)This thesis explores the mathematical concepts of differential forms and their applications in higher dimensional geometries, known as manifolds. We will see how the topological invariants of a geometry are related to ... -
Revealing Silicon’s Delithiation Behaviour through Empirical Analysis of Galvanostatic Charge–Discharge Curves
(Peer reviewed; Journal article, 2023-04)The galvanostatic charge–discharge (GCD) behaviour of silicon (Si) is known to depend strongly on morphology, cycling conditions and electrochemical environment. One common method for analysing GCD curves is through ... -
Techno-economic assessment of decarbonisation technologies for the iron and steel industry
(PhD Theses;704, Doctoral thesis, 2023)Rapid decarbonisation of all segments of the economy is essential to limit the global mean surface temperature rise to 1.5ºC. Industries contribute to approximately a quarter of the global energy related emissions but have ... -
