AUTOCORRELATION AND CROSS-CORRELATION FLOW ANALYSIS ALONG THE CONFLUENCE OF THE KUPA AND SAVA RIVERS
Rudarsko-geološko-naftni Zbornik, 2021 In this paper, an autocorrelation and cross-correlation analysis of the flow of the Kupa and Sava rivers was performed. The analysis was performed at hydrological stations close to the confluence of these two rivers near the city of Sisak, based on data ...

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 ...

A NEW METHOD FOR SIDELOBE SUPPRESSION IN THE AMBIGUITY FUNCTION OF SIGNALS MODULATED BY PSEUDO-RANDOM SEQUENCES [PDF]
Radio Physics and Radio AstronomySubject and Purpose. One of the main challenges in achieving high-accuracy radar target parameter determination and improving radar system noise immunity is the presence of sidelobes in the ambiguity function of the used signals, especially when these ...

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)

On Niho type cross-correlation functions of m-sequences
Finite Fields and Their Applications, 2007 The authors take a prime power \(q=p^k\) and a positive integer \(d\) of the form \(d\equiv 1\pmod {q-1}\) and study the number of solutions \(x\in \text{GF}(q^2)\) of the equation \((x+1)^d=x^d+1\). They prove various results concerning this number of the following flavor. Write \(d=(q-1)s+1\).

Atmospheric stellar parameters from cross-correlation functions [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 The increasing number of spectra gathered by spectroscopic sky surveys and transiting exoplanet follow-up has pushed the community to develop automated tools for atmospheric stellar parameters determination. Here we present a novel approach that allows the measurement of temperature ($T_{\rm eff}$), metallicity ($[{\rm Fe}/{\rm H}]$) and gravity ($\log
