In order for your survey to be representative for an entire population, you need to calculate the number of respondents: the survey sample size. Here's how!
As we all know, the calculation of load capacity is a very important work in gear design [25,26], which is closely related to the meshing state of gear teeth. In the process of gear transmission, the gear teeth of the driven wheel bear the meshing force from the teeth of the driving...
ai = additive effect calculated by ordinary least square regression (OLS) for each spectrum on the mean spectrum of all spectra; bi = multiplicative effect calculated by ordinary least square regression (OLS) for each spectrum on the mean spectrum of all spectra. The preprocessing methods are use...
// Moving the to be tested bit to the highest position saves us masking. if (goodMask << x >= 0) return false; final int numberOfTrailingZeros = Long.numberOfTrailingZeros(x); // Each square ends with an even number of zeros. if ((numberOfTrailingZeros & 1) != 0) return false...

Specifically, the ξ values calculated by LES for low b or high P were generally lower than those obtained by the empirical formulas. Conversely, the empirical formulas resulted in lower ξ values for high b or low P values. To quantify the differences, the root mean square relative errors ...
The degrees of matching between the results from the PTF models and the values obtained from the in situ and laboratory measurements were investigated based on the root-mean-square deviation (RMSD), Nash–Sutcliffe efficiency (NSE), and determination coefficient (R2). The statistical relationships ...
