Defoliant spraying is an important aspect of mechanized cotton harvesting.Fully and uniformly spraying defoliant could improve the quality of defoliation and reduce the impurity content in cotton.Improving the coverage of defoliant droplets in the middle and lower layers of cotton and ensuring the full and even dispersion of droplets in the cotton
The Cramér-Rao Bound (CRB) is a powerful tool to assess the performance limits of a parameter estimation problem for a given statistical model.In particular, the Gaussian CRB (i.e., the CRB obtained assuming the data are Gaussian) corresponds to the worst case; giving the largest CRB among a large class of data distributions.This makes it v
In this article, we present some elements of Gaston Bachelard epistemology as the Epistemological Andrographis Profile for discussing of aspects related to the teaching of chemistry.Our goal was to propose a model of Epistemological Profile for the concept of “transformations”, from the chemistry textbooks of the first grade of high school appr
