The cross-correlation between galaxies of different luminosities and colors

, 2007
We study the cross-correlation between galaxies of different luminosities and colors, using a sample selected from the SDSS Dr 4. Galaxies are divided into 6 samples according to luminosity, and each of these samples is divided into red and blue ...

IM session identification by outlier detection in cross-correlation functions [PDF]

2015 49th Annual Conference on Information Sciences and Systems (CISS), 2015
The identification of encrypted Instant Messaging (IM) channels between users is made difficult by the presence of variable and high levels of uncorrelated background traffic. In this paper, we propose a novel Cross-correlation Outlier Detector (CCOD) to identify communicating end-users in a large group of users.

Diagnosing aerosols in extrasolar giant planets with cross-correlation function of water bands [PDF]

, 2018
Transmission spectroscopy with ground-based, high-resolution instruments provides key insight into the composition of exoplanetary atmospheres. Molecules such as water and carbon monoxide have been unambiguously identified in hot gas giants through cross-

Cross-Correlation Functions for a Neuronal Model

Biophysical Journal, 1974
Cross-correlation functions, R(XY)(t,tau), are obtained for a neuron model which is characterized by constant threshold theta, by resetting to resting level after an output, and by membrane potential U(t) which results from linear summation of excitatory postsynaptic potentials h(t). The results show that: (1) Near time lag tau = 0, R(XY)(t,tau) = f(U)

Measurement of the dipole in the cross-correlation function of galaxies [PDF]

Journal of Cosmology and Astroparticle Physics, 2017
It is usually assumed that in the linear regime the two-point correlation function of galaxies contains only a monopole, quadrupole and hexadecapole. Looking at cross-correlations between different populations of galaxies, this turns out not to be the case.

Joint multifractal analysis based on the partition function approach: analytical analysis, numerical simulation and empirical application

New Journal of Physics, 2015
Many complex systems generate multifractal time series which are long-range cross-correlated. Numerous methods have been proposed to characterize the multifractal nature of these long-range cross correlations.

Horizontal spatial correlation of reverberation for rough sea-bottom interface [PDF]

MATEC Web of Conferences, 2019
Correlation sonar, which estimates the velocity of vessel utilizing the principle of waveform invariance, can achieve the sampling of the horizontal spatial correlation of sea-bottom reverberation. The horizontal spatial correlation can be expressed as a
