Partial discharge pattern analysis using support vector

A parallel-plane electrode system enclosed in a chaer filled with SF 6 gas is studied here. A Perspex spacer of 15 mm height and 15 mm diameter was placed between the two parallel plate electrodes , .The defects were created by attaching cylindrical stainless steel metallic particles of length L = 2 and 3 mm and diameter d = 0.5 mm on the spacer surface.

Convergence Properties of the Nelder--Mead Simplex …

2018-9-18 · The Nelder--Mead simplex algorithm, first published in 1965, is an enormously popular direct search method for multidimensional unconstrained minimization. Despite its widespread use, essentially no theoretical results have been proved explicitly for the Nelder--Mead algorithm. This paper presents convergence properties of the Nelder--Mead algorithm applied to strictly convex functions in

An SF6 purifiion process utilizing gas hydrate

A sulfur hexafluoride (SF 6) separation/purifiion process utilizing gas hydrate formation has been known for a while but its appliion to industrial use has not been attempted.A system with this process was developed for used SF 6 gas from heavy electric equipment. SF 6 hydrate formation equilibrium data and SF 6 hydrate formation rate data were collected with a batch reactor.
