Cross-correlation function in the interpretation of potential fields anomalies of strike-slip nature [PDF]

open access: yesE3S Web of Conferences, 2023
In the study, a comparison of correlation characteristics that can be obtained when analyzing areal geophysical data in COSCAD 3D, GIS INTEGRO software, as well as in custom software with a novel approach, has been conducted.

Nonreciprocal Green’s function retrieval by cross correlation

open access: yesThe Journal of the Acoustical Society of America, 2006
The cross correlation of two recordings of a diffuse acoustic wave field at different receivers yields the Green’s function between these receivers. In nearly all cases considered so far the wave equation obeys time-reversal invariance and the Green’s function obeys source-receiver reciprocity.

Fluctuations of thermal variables investigated by cross-correlation function

open access: yesPhysical Review E
Fluctuations in conjugate thermodynamic variables are studied using the cross-correlation function. A new procedure is given enabling the derivation of fluctuation formulas for a system in equilibrium. Specifically, the cross-correlation function between heat and temperature is employed for thermal variables.

A Cross-Correlational Analysis between Electroencephalographic and End-Tidal Carbon Dioxide Signals: Methodological Issues in the Presence of Missing Data and Real Data Results

open access: yesSensors, 2016
Electroencephalographic (EEG) irreducible artifacts are common and the removal of corrupted segments from the analysis may be required. The present study aims at exploring the effects of different EEG Missing Data Segment (MDS) distributions on cross ...

On the possibility of breaking the heterodyne detection quantum noise limit with cross-correlation

open access: yes, 2021
The cross-correlation sensitivity of two identical balanced photodiode heterodyne receivers is characterized. Both balanced photodiodes receive the same weak signal split up equally, a situation equivalent to an astronomical spatial interferometer.

CROSS-CORRELATION ANALYSIS OF THE SPATIAL INTERACTIONS BETWEEN TISSUE COMPARTMENTS OF THE RENAL CORPUSCLE

open access: yesImage Analysis and Stereology, 2011
The renal corpuscle is a multi-compartment unit of kidney morphology which is important for normal ultrafiltration of blood. Its structure is perturbed during ontogeny, disease and experimental manipulation.

Optimization of the Unambiguity of Cross-Correlated Ultrasonic Signals through Coded Excitation Sequences for Robust Time-of-Flight Measurements

open access: yesSignals, 2021
The cross-correlation function (CCF) is an established technique to calculate time-of-flight for ultrasonic signals. However, the quality of the CCF depends on the shape of the input signals. In many use cases, the CCF can exhibit secondary maxima in the
