Directly applying the B-spline interpolation function to process plate cams in a computer numerical control (CNC) system may produce verbose tool-path codes and unsmooth trajectories. This paper is devoted addressing problem of fitting for cam pitch curves. Considering that curve needs meet motion law follower approximate curve, we use radial error quantify effects curve. The thus boils down so...

Abstract The Transiting Exoplanet Survey Satellite (TESS) is continuing its second extended mission after 55 sectors of observations. TESS publishes full-frame images (FFIs) at a cadence 1800, 600, or 200 s, allowing light curves to be extracted for stars beyond limited number pre-selected stars. Simulations show that thousands exoplanets, eclipsing binaries, variable stars, and other astrophys...

in this study, the incomplete gamma function, an exponential function, a mixed-log function and a polynomial function were evaluated to describe the lactation curve in moroccan holstein-friesian dairy cows. data from 1990 to 1999, comprising 77130 monthly milk yields of 6029 dairy cows in 280 dairy herds, were used. edits were carried out by considering the lactation length (5 d and
