The results of the derivative method were validated by studying flatness factor, a quantitative measure of local intermittency in the wavelet coefficients at various scales.
The residual-based approach is more efficient than the derivative method in determining an element partition that results in a feasible optimal solution close to the optimal solution obtained by a tray-by-tray model.
The derivative method has been found as an easy and accurate method to calculate the optical bandgap compared to the Kubelka-Munk method.
The values of T C obtained from the linear extrapolation are about 23 K higher than those calculated from the derivative method.
They are also used for estimating wellbore and reservoir parameters in order to support the interpretation from the derivative method or type-curve after the analysis.
Considering the results obtained from the methods, it can be concluded that there is a better agreement between the derivative method with the observed blueshift in reflectance spectra and the Kubelka-Munk method due to the less approximations of the derivative method.
The derivative method was applied for measurement of Eg. In this method, the first derivative of the absorbance was evaluated near the fundamental absorption edge, leading to Eg [29].
Similar to the derivative method in the work in [10], the partial derivative of Equation 23 with respect to the baseline b is calculated, and Equations 18 and 19 are submitted into the result.
Melting temperatures were determined by the derivative method.
For more accurate identification, 2-DE analysis using the derivative method of 3-NT to aminotyrosine by sodium dithionate and immunoprecipitation will probably be necessary, as well as analysis of the nitrated tyrosine residue site and the ratio in the nitrated protein sequence.
