A power factor control system for a rectifier is operative through the generation of estimators of control input parameters (a peak squared input AC voltage E.sub.m.sup.2 and load power) and by the use of these substantially ripple free ... RW Farrington,ME Jacobs,WP Wilkinson - US 被引...
DEVICE FOR COMPUTING FUNCTION: X EQUALS SQUARE ROOT FROM SQUARED A PLUS SQUARED BCHEKUSHKIN VSEVOLOD V,SU
46) suggested that for construct X and construct Y, discriminant validity is established when AVEs associated with both constructs are greater than the shared variance (i.e., squared correlation; SV) between X and Y. In other words, the latent variable explains more variance of the indicators ...
The modulus of a complex number is how far it is from the point where the real and imaginary axes cross (0,0). It is the square root of the real part squared plus the imaginary part squared.Here is how the modulus is calculated for complex number 9+12i:...

The first term is the least squares criterion using the basis functions as explanatory variables, and the second term represents the wiggliness of f(x) as measured by its squared second derivative over some range [a,b], typically the minimum and maximum values of x in the sample. The smoot...
Adjusted R-squared 0.890 Notes: Non-std coef: Non-standardized coefficients. P-values are given in parenthesis. *** represents statistical significance at the 1% level. BRN is expressed in weekly moving average (WMA). The regression equation is expressed as TOPIX=B·BRN+dummyi+Constant (i=...
significant for all CGI groups; however, only cluster 1 to 3 exhibited a high effect size, which suggests that the strongest change in chromatin state proportions between healthy and cancerous cells affects these clusters (chi-squared P values <1.7 × 10−10 in Supplementary Table 9)....
