Sensors, 2022 The grounding resistance of a substation is an important parameter that should be designed within a reasonable range to prevent operational accidents from damaging electrical equipment due to overvoltage and ensure the safe operation of an electrical ...

A New Coefficient of Correlation [PDF]
Journal of the American Statistical Association, 2019 –Is it possible to define a coefficient of correlation which is (a) as simple as the classical coefficients like Pearson’s correlation or Spearman’s correlation, and yet (b) consistently estimates some simple and interpretable measure of the degree of ...

Inverting the Angular Correlation Function [PDF]
, 1999 The two point angular correlation function is an excellent measure of structure in the universe. To extract from it the three dimensional power spectrum, one must invert Limber's Equation.

Determining $\Omega$ from cluster correlation function
, 1998 It is shown how data on the cluster correlation function can be used in order to reconstruct the density of the pregalactic density field on the cluster mass scale.

QCD sum rules with two-point correlation function [PDF]
, 1999 We construct three different sum rules from the two-point correlation function with pion, $i\int d^4x e^{iq\cdot x} $, beyond the soft-pion limit. The PS and PV coupling schemes in the construction of the phenomenological side are carefully considered in

Correlation function of dyonic strings
, 2011 We investigate the two- and three-point correlation functions of the dyonic magnon and spike, which correspond to the solitonic string moving in the Poincare AdS and three-dimensional sphere. We show that the coupling between two dyonic magnons or spikes

Microscopic derivation of the hydrodynamic equations for the superfluid fermi-systems
Condensed Matter Physics, 2005 Starting from the first principles of statistical mechanics, the two-fluid hydrodynamics of superconductor in ideal approximation is constructed. The system of equations of motion for normal and anomalous correlation functions is used for hydrodynamic ...

Testing mode-coupling theory for a supercooled binary Lennard-Jones mixture I: The van Hove correlation function. [PDF]
Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 1995 We report the results of a large scale computer simulation of a binary supercooled Lennard-Jones liquid. We find that at low temperatures the curves for the mean squared displacement of a tagged particle for different temperatures fall onto a master ...

Evolution of the Cluster Correlation Function
, 2003 We study the evolution of the cluster correlation function and its richness-dependence from z = 0 to z = 3 using large-scale cosmological simulations. A standard flat LCDM model with \Omega_m = 0.3 and, for comparison, a tilted \Omega_m = 1 model, TSCDM,
