Iterative Frequency-Domain Response of Floating Offshore Wind Turbines with Parametric Drag
Journal of Marine Science and Engineering, 2018 Methods for coupled aero-hydro-servo-elastic time-domain simulations of Floating Offshore Wind Turbines (FOWTs) have been successfully developed. One of the present challenges is a realistic approximation of the viscous drag of the wetted members of the ...

Time- vs. Frequency-domain Identification of Parametric Radiation Force Models for Marine Structures at Zero Speed [PDF]
Modeling, Identification and Control, 2008 The dynamics describing the motion response of a marine structure in waves can be represented within a linear framework by the Cummins Equation. This equation contains a convolution term that represents the component of the radiation forces associated ...

Cointegration in frequency domain [PDF]
Journal of Time Series Analysis, 2002 Existence of a cointegration relationship between two time series in the time domain imposes restrictions on the series zero‐frequency behaviour in terms of their squared coherence, phase and gain, in the frequency domain. I derive these restrictions by studying cross‐spectral properties of a cointegrated bivariate system.

Current reversals in a rocking ratchet: the frequency domain [PDF]
, 2011 Motivated by recent work [D. Cubero et al., Phys. Rev. E 82, 041116 (2010)], we examine the mechanisms which determine current reversals in rocking ratchets as observed by varying the frequency of the drive.

Measuring Online Battery AC Resistance Using a DC-DC Converter With Time and Frequency Hybrid Method
IEEE AccessThe estimation of battery state is important for ensuring the stability of batteries. The AC resistance of a battery is one of the factors used to estimate the battery state, and is measured using a Fast Fourier Transform (FFT), a technique that analyzes
