A Sharp Uniform Bound for the Distribution of Sums of Bernoulli Trials [PDF]

Combinatorics, Probability and Computing, 2015
In this note we establish a uniform bound for the distribution of a sum Sn=X1+···+Xn of independent non-homogeneous Bernoulli trials. Specifically, we prove that σn(Sn = j) ≤ η, where σn denotes the standard deviation of Sn, and η is a universal constant.

Stereoscopic plant-protection system integrating UAVs and autonomous ground sprayers for orchards

Frontiers in Plant Science, 2022
For orchard plant protection, conventional large machines and small sprayers are practically restricted by either narrow planting intervals with dense leaves or their inadequate penetration power, which leads to an unsatisfactory effect of spray.
