Abstract: The present disclosure relates to a method for stochastic inspections on power grid lines based on unmanned aerial vehicle-assisted edge computing. According to the method, a stochastic distributed inspection unmanned aerial vehicle is adopted to acquire video images on a target power grid area, which can reduce funds and time costs of inspections. With assistance of superior unmanned aerial vehicle, a goal is to minimize energy consumption of an unmanned aerial vehicle system and extend operation time of the unmanned aerial vehicles under same payload conditions, while processing video image data collected from the inspection unmanned aerial vehicles. The near-far effect generated by communications between mobile unmanned aerial vehicles is eliminated by introducing a NOMA, and position coordinates, system resource allocations and task offload decision schemes are solved by using a method of combining a DDPG algorithm in a Deep reinforcement learning with a genetic algorithm.

Abstract: A multi-tag concurrent identification method and a system for a query tree based on feature groups are provided in this disclosure. In the disclosure, a whole data string space is divided into a plurality of disjoint subsets according to features of data strings returned by tags, where each of the subsets contains several different data strings, each of the data strings in the each of the subsets is regarded as a complete tag ID or a partial ID, and the each of the subsets corresponds to a unique query prefix, a length of the prefix is fixed and does not dynamically increase with an actual location of a collision, and when multiple data strings from a same subset return at a same time, a reader is capable of identifying them at a same time in a slot.

Abstract: A composition suitable for forming a paint marking on a roadway comprises a polyfunctional acrylate having at least four acrylate groups, an epoxy component and a polyfunctional amine. The polyfunctional acrylate reacts with the polyfunctional amine to form an adduct with secondary amine groups. The secondary amine reacts with the epoxy component to yield a chemically high crosslinked material having a no track time of less than about five minutes.

Abstract: A composition suitable for forming a paint marking on a roadway comprises a secondary amine adduct having at least two secondary amine groups, an amine diluent and a polyisocyanate. The secondary amine adduct and the amine diluent react with the polyisocyanate to yield a chemically high crosslinked material having a no track time of about two minutes.

Abstract: A polymeric composition exhibiting a fast cure rate composition comprises a polyfunctional urethane acrylate component; an epoxy component; and a polyfunctional amine component. The polyfunctional acrylate component and the polyfunctional amine component have sufficient functionalities such that the polyfunctional urethane acrylate component reacts with the polyfunctional component to form a secondary amine component. The secondary amine then reacts with the epoxy component such that a crosslinked polymeric material is formed.
