This paper derives averaged-value models for 6- and 12- pulse transformer-diode rectifier units and validates their utilities by comparison of the resultant transient and steady state behaviors with those obtained from extensive simulations of detailed 6- and 12-pulse diode rectifier models. It is ...

In this paper, a subgroup least squares and a convex clustering are introduced for inferring a partially heterogenous linear regression that has potential application in the areas of precision marketing and precision medicine. The homogenous parameter and the subgroup-average of the heterogenous parameters...

Average and substorm conditions in the lobe and plasma sheet regions of the earth's magnetotail are studied as a function of downstream distance and east-west location using ISEE 3 magnetometer and plasma analyzer measurements. On the basis of 756 magnetopause crossings a low-latitude magnetotail ...
Attractiveness is a proposed universal cue to overall biological quality. Nonetheless, local raters and raters of the same ethnicity may be more accurate in assessing the cues for attractiveness than distant and unfamiliar raters. Shared ethnicity and sh
