PARTIAL DISCHARGES AND NOISE DISCRIMINATION USING MAGNETIC ANTENNAS, THE CROSS WAVELET TRANSFORM AND SUPPORT VECTOR MACHINES

Partial Discharges and Noise Discrimination Using Magnetic Antennas, the Cross Wavelet Transform and Support Vector Machines

This paper presents a wavelet analysis technique together with support vector machines (SVM) to discriminate partial off white 5000 puffs discharges (PD) from external disturbances (electromagnetic noise) in a GIS PD measuring system based on magnetic antennas.The technique uses the Cross Wavelet Transform (XWT) to process the PD signals and the ex

A model of quantum gravity with emergent spacetime

Abstract We construct a model of quantum gravity in which dimension, topology and geometry of spacetime are dynamical.The microscopic degree of freedom is a real rectangular matrix whose rows label internal flavours, and columns label spatial sites.In the limit that the size of the matrix is large, the sites can collectively form a spatial manifold

A grid-based sample design framework for household surveys [version 1; peer review: 2 approved, 1 approved with reservations]

Traditional sample designs for household surveys are contingent upon the availability of a representative primary sampling frame.This is defined using enumeration units and population counts retrieved from decennial national censuses that can become rapidly inaccurate in highly dynamic demographic settings.To tackle the need for representative samp
