Motion planning is critical for ensuring precise and efficient operations of unmanned aerial vehicles (UAVs).While polynomial Kitchen Wear parameterization has been the prevailing approach, its limitations in handling complex trajectory requirements have motivated the exploration of alternative methods.This paper introduces a finite Fourier series
Abstract Alkalinity production is one of the most typical and widespread salinization hazards on the Loess Plateau.Based on the characterization of typical flooding sites and the results of salt monitoring, this study investigates the deterioration mechanism of salinization on Zhouqiao site.The orthogonal test was used to simulate the effects of di
We used geometric morphometrics to determine variation in the morphology of the forewings of individuals in 20 populations ALOE VERA NEEM SHAMPOO of Calopteryx splendens s.l.in Eurasia and related these to the circum-specific taxonomy of this taxon.We found differences in shape, with the largest and smallest centroid size of the wings in adjacent n
