In this paper, the defect simulator for high voltage sulfur hexafluoride gas insulated composite electrical apparatus is developed. the device consists of four parts: sulfur hexafluoride gas chamber, solid insulator, defect simulator, observation and measurement device. the defect simulator can effectively simulate free metal particle discharge, tip discharge, suspension discharge and air gap discharge. A real-type integrated defect simulator based on GIS is developed, and the partial discharge signal is tested on the simulator, the change trend of decomposed gas with time is detected. Based on this, an artificial intelligence classification method combining fuzzy ISODATA algorithm and ant colony algorithm is proposed, and the structure parameters of the two algorithms are optimized by PSO algorithm. the field application results of HV combined electrical appliances show that the proposed method is effective. the fault type diagnosis method can effectively judge the fault mode intelligently according to time series of SF6 micro-decomposition gas and typical micro-decomposition gas. this paper not only collects the original classification data from the hardware platform of the defect simulator, but also develops an artificial intelligence classification algorithm software system which is easy to be programmed. It can be directly and effectively used to diagnose and evaluate the type of insulation defect in the field practical engineering of GIS. It has certain theoretical guidance value for GIS equipment fault diagnosis and patternrecognition.

the problem of n-queens was introduced by Gauss (n = 8). It is a classical search problem in the field of machine learning. Back tracking is frequently applied to solve such constraint based problems, but it often suffers from exponential growth of computing steps/time as n increases. this paper describes the RAKHYA'S Method, which is an alternative approach to the method of back tracking. It is capable of finding more than one solutions for all values of n>3 in very few steps. there is a significant reduction in the number of steps, for instance, it takes 1,749,317,724 steps to achieve the first solution of 30-queens problem by backtracking whereas RAKHYA'S Method presents its first solution in 32 steps.

In this paper we conduct a comparative study of local key-point detectors and local descriptors for the specific task of mobile document classification. A classification architecture based on direct matching of local descriptors is used as baseline for the comparative study. A set of four different key-point detectors and four different local descriptors are tested in all the possible combinations. the experiments are conducted in a database consisting of 30 model documents acquired on 6 different backgrounds, totaling more than 36.000 test images.
We propose an improved YOLOv4 small target detection method for small target foreign object (FOD) recognitionthat requires as few detection accuracy, speed, and model volume parameters as possible so that it can be e...
