Implementation of Aerial Application System for Application Uniformity
Journal of the Korea Academia-Industrial cooperation Society, 2016 The aim of this study was to prevent the decrease in crop output by disease and insect pests and excessive spraying of agricultural pesticides by application uniformity. A 3m height and 15km/h speed is difficult to maintain with an unmanned helicopter for aerial application, which has been affected by the controlling habits and methods or environmental

Uniform chain decompositions and applications [PDF]
Random Structures & Algorithms, 2021 AbstractThe Boolean lattice is the family of all subsets of ordered by inclusion, and a chain is a family of pairwise comparable elements of . Let , which is the average size of a chain in a minimal chain decomposition of . We prove that can be partitioned into chains such that all but at most proportion of the chains have size .
