Frequency and prognostic factors of olfactory dysfunction after traumatic brain injury
(Journal article; Peer reviewed, 2018)Objective: To assess the frequency and factors associated with posttraumatic olfactory dysfunction, including anosmia, in a follow-up of patients with moderate and severe traumatic brain injury (TBI). Methods: The setting ... -
Frequency based Wind Turbine Gearbox Fault Detection applied to a 750 kW Wind Turbine
(Journal article, 2014)Reliability and availability of modern wind turbines are of increasing importance, for two reasons. The first is due to the fact that power grids around in the world depends at a higher and higher degree on wind energy, ... -
Frequency control and stability requirement on Hydro plants: System identification for performance and stability assessment
(Doctoral theses at NTNU;2019:303, Doctoral thesis, 2019)The Nordic transmission system operators (TSOs) have proposed new draft requirements for the providers of frequency containment reserves. These requirements include extensive tests to determine the dynamics of hydro power ... -
Frequency Control Evaluation for a Variable Speed Wind Power Plant in an Isolated Power System
(Master thesis, 2023)Behovet for fornybare energikilder vokser kontinuerlig. Energiproduksjonen i fremtidens kraftsystemer vil i store deler bestå av fornybare energikilder som vindkraft, vannkraft og solenergi. Selv om bruk av fornybare ... -
Frequency controlled agglomeration of pt-nanoparticles in sonochemical synthesis
(Peer reviewed; Journal article, 2022)Optimizing the surface area of nanoparticles is key to achieving high catalytic activities for electrochemical energy conversion devices. In this work, the frequency range (200 kHz–500 kHz) for maximum sonochemical radical ... -
Frequency Converter Solutions and Control Methods for Varible Speed Operation of Pumped Storage Plants
(Doctoral theses at NTNU;2023:399, Doctoral thesis, 2023)Pumped storage hydropower plants (PSHP) are widely used for bulk energy storage around the world. The variable speed operation of these plants further enables their capability to regulate the power in pump mode as well. ... -
Frequency Dependence of Bilge Keels
(Master thesis, 2018)The goal of this master's thesis is to inspect the damping generated by bilge keels. Two dimensional cross sections have been modeled both with and without bilge keels and simulated using the computational fluid dynamics ... -
Frequency Dependence of Microwave-assisted Electron-transfer Chemical Reactions
(Journal article; Peer reviewed, 2019)In this paper, the electron transfer reactions in the microwave field are studied. A classical theory is developed for a mix of reagents and polar frequency-dispersive and lossy solvent filling vessels excited by microwaves. ... -
Frequency dependent elastic properties of shales – Impact of partial saturation and stress changes
(Doctoral theses at NTNU;2017:151, Doctoral thesis, 2017)Shales are the most common constituent of the overburden of conventional hydrocarbon reservoirs. As such, they have a strong influence on seismic waves and knowledge about overburden mechanical properties is required for ... -
Frequency dependent polarisation switching in h-ErMnO3
(Journal article; Peer reviewed, 2018)We report an electric-field poling study of the geometric-driven improper ferroelectric h-ErMnO3. From a detailed dielectric analysis we deduce the temperature and frequency dependent range for which single-crystalline ... -
