Each training iteration consisted of an ensemble of 10,000 estimator trees, with the number of features per tree set to the square root of the total number of features. The impurity score was determined by Shannon entropy (‘gini’) to evaluate the quality of tree growing. Other parameters ...
A unique experimental method that is able to monitor this stochastic response is the detection of AE waves. The principle of the emission of acoustic waves in materials is analogous to earthquakes: Plastic deformation is caused by the local rearrangement of dislocation lines in a crystal, a proces...
It shows some distribution or feature of each testcase. The value is not accurate since I use square root or log10 for those large values, but you can know the rough magnitude. Here ld is long double, d is double, s is single, h is half. Also log is the log10 and error is the...
If we take the square root of both sides of Eq. (20), we obtain the following equation for the diffusion coefficient: $$\begin{aligned} \sigma ^\mu =\pm \sqrt{\frac{2 g_{\mu \mu } \epsilon _r i \hbar }{m}},\quad \mu =0..3. \end{aligned}$$ (41) If we use the ...
An estimate of a square root can be found by finding the two perfect square numbers within which a number lies. For example, let's use the number 210. 14 times 14 is 196, and 15 times 15 equals 225, so the square root of 210 is between 14 and 15. A more exact number can be ...

The average of these measures was used in the final analysis. We also calculated the standard error (the standard deviation of bulb angle divided by the square root of the count of the total bulb angle measurements), standard deviation, and coefficient of variation of bulb angle for each ...
Additionally, we accounted for the shape of the SUs through the maximum distance (MD) from the highest to the lowest point along a SU boundary and computed the elongation index (DA) as the maximum distance divided by the square root of the SU area. This index represents large SUs when ...
(Nunnally,1994), indicating the convergent validity of the current study. Following the suggestion of Fornell and Larcker (1981b), we assessed the discriminant validity of this study. The results of Table3show that the square root of AVE for all variables was greater than the correlation ...
