Fiber-optic extrinsic Fabry–Perot (EFPI) sensors have been successfully used for a wide
range of applications. The recent progress in EFPI sensors is reviewed in this paper. First …

The Savitzky–Golay smoothing and differentiation filter optimally fits a set of data points to a
polynomial in the least-squares sense. The Savitzky–Golay filter has been developed and …

The Savitzky–Golay (SG) filters are generally used for smoothing and differentiation in many
fields. The properties of the SG smoothing filters have been well studied. However, the …

Carrying out supervising of sawing equipment through advanced sensor is an important
study in modern automatic sawing technology. The application of monitoring techniques can …

Compared with passive fault diagnosis (PFD) techniques, the research on active fault
diagnosis (AFD) techniques is insufficient. The existing AFD methods generally include set …

The quaternion Fourier transform–a generalized form of the classical Fourier transform–has
been shown to be a powerful analyzing tool in image and signal processing. This paper …

We generalize the linear canonical transform (LCT) to quaternion‐valued signals, known as
the quaternionic linear canonical transform (QLCT). Using the properties of the LCT we …

In ultrasound elastography, tissue axial strains are calculated from the gradient of the
estimated axial displacements. However, the common differentiation operation amplifies the …

In this paper we present two n-layer channel routing algorithms that guarantee successful
routing of the channel for n greater than three. The first is linear and optimal given a VHV …

In order to improve the reliability of power transmission lines, one of the key issues is to
reduce the hazard of contamination flashovers. Presently, the most efficient way is to clean …
