This paper presents an analytical continuous smoothing method for the five-axis toolpath by simultaneously scheduling the tool position and tool orientation trajectories.In order to ensure the high-order continuous, the peak-controlled jerk and arclength-parameterized property, a novel curve “airthoid” is proposed for the first time.T
In the title compound, C9H11N3O, the benzene ring is disordered over two positions with refined occupancies of 0.922 (5) and 0.078 (5).The program PLATON [Spek (2009).Acta Cryst.D65, 148–155] recommends the solution in the space group C2/m with a = 7.3050 (3), b = 6.6745 (2), c = 18.3853 (
Parrots of the genus Amazona are among the most threatened species of the Order Pscittaciformes.This work describes allozyme polymorphisms in three Amazon parrot species - the Blue-fronted Amazon (Amazona aestiva), the Orange-winged Amazon (Amazona amazonica), and the Festive Amazon (Amazona festiva) -, and provides useful data for the evaluation o
