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 ...

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

Mirror-induced reflection in the frequency domain
Nature Communications, 2022 We show frequency domain mirrors that provide reflections of optical mode propagation in the frequency domain. We theoretically investigated the mirror properties and experimentally demonstrate it using polarization and coupled-resonator-based coupling ...
