Fractal Analysis and Its Application on Time-Series Data - An Innovative Method for Condition Monitoring of Hole Cleaning Operations
(Master thesis, 2022)Innenfor hullrensing i oljeboring bransjen, har ny og moderne utvikling av sensorer gjort det mulig å monitorere tilstanden til en boring- og renseoperasjon mens den er i drift. Dette medfører en stor mengde data som kan ... -
Fractional-order Control: Nyquist Constrained Optimization
(Peer reviewed; Journal article, 2020)The adoption of fractional calculus in control systems has enabled the synthesis of new controllers with fractional-order derivatives and integrals. Several optimization-based methods for tuning of linear fractional-order ... -
Fragmentation, Centralisation and Policy Learning: An Example from China’s Wind Industry
(Journal article; Peer reviewed, 2014)This paper seeks to understand what government mechanisms have allowed China’s wind industry to grow as fast as it has over the past ten years. Instead of formal rules and regulations, this paper focuses on specific ... -
Frame invariant neural network closures for Kraichnan turbulence
(Peer reviewed; Journal article, 2022)Numerical simulations of geophysical and atmospheric flows have to rely on parameterizations of subgrid scale processes due to their limited spatial resolution. Despite substantial progress in developing parameterization ... -
Framework for produced water discharge management with flow-weighted mean concentration based economic model predictive control
(Peer reviewed; Journal article, 2022)Offshore discharges of produced water (PW) is heavily regulated by government authorities through flow-weighted mean concentration (FWMC). To cope with regulations, treatment facilities are commissioned to reduce the oil ... -
