Phase error evaluation technique based on Fourier transform for refractive index detection limit of microfluidic differential refractometer

Feature extraction and health status prediction in PV systems

“…However, these transforms only provide information about fre-quency. In [56] the authors propose the Fourier Transform with a window that provides both time and frequency information. However, the fixed window selection may not always be efficient for detecting critical non-stationary disturbances such as three-phase faults and short circuits that are associated with transients [2].…”
