Cross-Correlated Contrast Source Inversion

IEEE Transactions on Antennas and Propagation, 2017
In this paper, we improved the performance of the contrast source inversion (CSI) method by incorporating a so-called cross-correlated cost functional, which interrelates the state error and the data error in the measurement domain. The proposed method is referred to as the cross-correlated CSI.

All-optical periodic code matching by a single-shot frequency-domain cross-correlation measurement

, 2009
Optical single-short measurement of the cross-correlation function between periodic sequences is demonstrated. The sequences are encoded into the broadband ultrashort phase-shaped pulses which are mixed in the nonlinear medium with additional amplitude ...

The influence of noise sources on cross-correlation amplitudes [PDF]

, 2012
We use analytical examples and asymptotic forms to examine the mathematical structure and physical meaning of the seismic cross correlation measurement.

Source separation and localisation via tensor decomposition for distributed arrays

The Journal of Engineering, 2019
This study focuses on the problem of power spectra separation and localisation of multiple sources using distributed arrays. First, the array structure and signal model are discussed. By cross-correlating the multi-channel received signals in time-domain,

Baryon acoustic oscillations with the cross-correlation of spectroscopic and photometric samples

, 2013
The baryon acoustic oscillation (BAO) experiment requires a sufficiently dense sampling of large-scale structure tracers with spectroscopic redshift, which is observationally expensive especially at high redshifts $z\simgt 1$.

The Cross-Correlation between Galaxies and Groups: Probing the Galaxy Distribution in and around Dark Matter Haloes

, 2005
We determine the cross-correlation function between galaxies and galaxy groups, using both the Two-Degree Field Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS).

Observational Constraints on Kinetic Gravity Braiding from the Integrated Sachs-Wolfe Effect

, 2012
The cross-correlation between the integrated Sachs-Wolfe (ISW) effect and the large scale structure (LSS) is a powerful tool to constrain dark energy and alternative theories of gravity.

Cosmology from cross correlation of CMB lensing and galaxy surveys

, 2013
In recent years cross correlation of lensing of the Cosmic Microwave Background (CMB) with other large scale structure (LSS) tracers has been used as a method to detect CMB lensing.

THE EFFICIENCY OF SELECTIVE TIDAL STREAM TRANSPORT IN GLASS EEL ENTERING THE GIRONDE (FRANCE)

Knowledge and Management of Aquatic Ecosystems, 2005
Traditional estimation of migration speed is based on telemetry or marking of individual fish. Only a few numbers of fishes (or batches) are followed, often over short periods of time.

Application of early warning signs to physiological contexts: a comparison of multivariate indices in patients on long-term hemodialysis

Frontiers in Network Physiology
Early warnings signs (EWSs) can anticipate abrupt changes in system state, known as “critical transitions,” by detecting dynamic variations, including increases in variance, autocorrelation (AC), and cross-correlation.
