When current transformer is saturated, mainly due to the presence of an exponentially decaying DC component in fault current, its secondary has a distinctive distorted waveform which significantly differs from primary (true) waveform. It leads underestimation value calculated by relay protection compared true value. Thus, turn, results trip time delay or even devices operation failure, since se...

It is necessary to carry out experiments on cores with different degrees of crack development when studying the seepage law cracked reservoirs and evaluating cracks. The experiment in laboratory requires microcrack development; obtained via conventional drilling cannot meet requirements, efficacies evaluation methods geological parameters used for artificial cracks are not perfect. In this stud...

This paper offers insights into the diffusion and impact of artificial intelligence in science. More specifically, we show that neural network-based technology meets essential properties emerging technologies scientific realm. It is novel, because it shows discontinuous innovations originating domain put to new uses many application domains; quick growing, its dimensions being subject rapid cha...

Artificial compressibility methods aim to reduce the stiffness of compressible Navier-Stokes equations by artificially decreasing velocity acoustic waves in fluid. This approach has originally been developed as an alternative incompressible this avoids resolution a Poisson equation. paper extends method anisothermal low Mach number flows, allowing simulations subsonic flows submitted large temp...

The obstacle avoidance system of a drone affects the quality its flight path. artificial potential field method can react quickly when facing obstacles; however, traditional lacks consideration position information between drones and obstacles during flight, issues including local minima, unreachable targets, unreasonable techniques that lengthen times consume more energy get encountered. There...
