A coupled mix-mode cohesive law based on a cylindrical potential function
(Peer reviewed; Journal article, 2022)A novel mixed-mode cohesive law derived from a potential function is presented. The potential function is formulated using physical parameters that can be extracted from any fracture mechanics test capable of providing ... -
Coupled Mooring Systems for Floating Wind Farms
(Master thesis, 2014)In this work the feasibility of an integrated catenary loose mooring system for offshore floating wind turbines is investigated. The dynamic behavior of different wind farm layouts is analyzed employing the equation of ... -
Coupled mooring systems for floating wind farms
(Journal article; Peer reviewed, 2015)In this paper it is investigated if, by coupling the catenary mooring systems of a number of turbines, the number of lines and anchors needed and subsequently the costs could be reduced and what kind of dynamic phenomena ... -
Coupled reservoir-network simulations with ESP's and multiphase pump built in
(Master thesis, 2016)The present project is focused on evaluating dual boosting (production with seabed boosting and electric submersible pumps, ESPs, simultaneously) as an alternative to improve total oil production rate of subsea fields. ... -
Coupled Transport in Li-ion Battery Electrolytes
(Doctoral theses at NTNU;2024:187, Doctoral thesis, 2024)Electrolytes are materials that contain mobile charge carriers – ions. The electrolyte in lithium-ion batteries enables the transport of positive Li+ ions in between the electrodes during battery operation. The transport ... -
Coupled Transport of Heat, Mass and Charge in Ion Exchange Membranes - Aqueous Chloride Systems Relevant for Harvesting of Low-Grade Waste Heat

(Master thesis, 2018)The main objective of this thesis is do maintenance optimization for a system using AltaRica simulation tools. Maintenance optimization is based on the assessment of maintenance policy. Stochastic simulation is applied to ... -
Coupling and competition between ferroelectricity, magnetism, strain, and oxygen vacancies in AMnO3 perovskites
(Journal article; Peer reviewed, 2016)We use first-principles calculations based on density functional theory to investigate the interplay between oxygen vacancies, A-site cation size/tolerance factor, epitaxial strain, ferroelectricity, and magnetism in the ... -
Coupling currents and hysteresis losses in MgB2superconductors
(Journal article; Peer reviewed, 2014)MgB2 multi-filamentary superconductors are widely considered for use in dc applications. To expand the possible application range to ac apparatuses, the development of a low ac loss wire is needed. This development involves ... -
Coupling Field Observations and Geographical Information System (GIS)-Based Analysis for Improved Sustainable Urban Drainage Systems (SUDS) Performance
(Journal article; Peer reviewed, 2018)Urbanization and increased precipitation volumes and intensities due to climate change add pressure to the urban drainage system, resulting in increased flooding frequencies of urban areas and deteriorating water quality ... -
Coupling in the middle atmosphere related to the 2013 major sudden stratospheric warming
(Journal article; Peer reviewed, 2015)The previously reported observation of anomalous eastward gravity wave forcing at mesopause heights around the onset of the January 2013 major sudden stratospheric warming (SSW) over Trondheim, Norway (63° N, 10° E), is ... -
Coupling Input‐Output Tables with Macro‐Life Cycle Assessment to Assess Worldwide Impacts of Biofuels Transport Policies
(Journal article; Peer reviewed, 2018)Many countries see biofuels as a replacement to fossil fuels to mitigate climate change. Nevertheless, some concerns remain about the overall benefits of biofuels policies. More comprehensive tools seem required to evaluate ... -
