Compared with the direct method, the Gaussian-fitting and half-area results (panels B, C) predict the true FPD values quite accurately (Gaussian-fitting: r= 0.99968, intercept = 1.012, slope = 0.993. Half-area: r = 0.99969, intercept = 0.994, slope = 0.966).
We also adopted a Gaussian fitting for the RASS echo.
In addition, a Gaussian fitting for the PSi peak was performed to some XRD profiles.
A Gaussian fitting indicates that the maximal probability for nanocrystals' diameter is 4.4 nm.
Before the telluric correction of the target spectra, the intrinsic hydrogen absorption features of the standard A star are removed with a Gaussian fitting algorithm.
We demonstrate FPD parameter extraction using three methods: a direct, Gaussian fitting, and half-area approach.
A new Fiber Bragg Grating (FBG) wavelength demodulation scheme is studied in the paper, which consists of an improved de-noising method and Gaussian fitting peak searching algorithm.
Figure 8A shows the FPD histogram extracted from the Gaussian-fitting method.
In this method, we integrate a multi-Gaussian fitting feature extraction method and an LSTM-based damage identification method to develop a health monitoring system with available vibration signals.
Figures 6B and 6C provide the Gaussian-fitting and half-area method results.
