Gaussian curve is a curve with a classic bell shape that has a maximum around the average of the measured values and can be more or less narrow depending on the dispersion of the values around the average.
2a but the scale of the tissue region is zoomed in order to visualize well the Gaussian curve on the histogram bins.
Hence, on the basis of the Gaussian curve fitting based on the least square method for the settlement trough, the total volume loss [V.sub.L] and trough width ix can be determined.
As Uncertainty is calculated as SD, and 1SD is equal to 68 percent confidence on the Gaussian curve (Figure 2), it is reasonable to multiply the Uncertainty by a coverage factor (K) of 2 to attain a 2SD confidence level of 95 percent.

In [15], it is demonstrated that a Gaussian curve fitting substantially reduces the measurement errors of spectrally distorted FBG sensors by employing a binary search algorithm that calculates and compares MSE values at only logically selected positions.
It is called Gaussian because the image is blurred using a Gaussian curve (

The first category is based on the principle of localizing individual fluorescent molecules by Gaussian curve fitting of the emission spots.
When assessing linearity, it is acceptable to use the Gaussian curve as the x values are 'assigned' and assumed to have no error.
Indeed, by applying the fluctuation-dissipation theorem and modeling the out-of-phase component C" as a Gaussian curve (supposing temperature variable and frequency constant), [delta]T corresponds to the standard deviation of this Gaussian curve [52] and [T.sub.[alpha]] is its maximum.
