On the Possibility of Breaking the Heterodyne Detection Quantum Noise Limit With Cross-Correlation
(2018)
The cross-correlation sensitivity of two identical balanced photodiode heterodyne receivers is characterized. Both the balanced photodiodes receive the same weak signal split up equally, a situation equivalent to an ...
Amplitude distortion of measured leak noise signals caused by instrumentation: Effects on leak detection in water pipes using the cross-correlation method
(2019-11-24)
A common way to detect and locate leaks in buried water pipes is to use leak noise correlators. Vibration or acoustic signals are measured on or in the pipe using sensors placed either side of the leak, and the difference ...

The atacama cosmology telescope: measuring radio galaxy bias through cross-correlation with lensing
(2015)
We correlate the positions of radio galaxies in the FIRST survey with the cosmic microwave background lensing convergence estimated from the Atacama Cosmology Telescope over 470 deg(2) to determine the bias of these galaxies. ...
Fully differential cross sections in single ionization of helium by ion impact: Assessing the role of correlated wave functions
(Elsevier Science, 2008-02)
We study the effect of final state dynamic correlation in single ionization of atoms by ion impact analyzing fully differential cross sections (FDCS). We use a distorted wave model where the final state is represented by ...
Cross-stratigraphies from a seismically active mud lens off Peru indicate horizontal extensions of laminae, missing sequences, and a need for multiple cores for high resolution records
(Elsevier, 2014)
Marine laminated sediments in dysoxic areas of the ocean floor are an excellent archive for high-resolution climate reconstructions. While the existence of discontinuities produced by natural events, such as underwater ...
Integrating cross-correlation and relaxation algorithms for particle tracking velocimetry
(Springer, 2011)
An integrated cross-correlation/relaxation algorithm
for particle tracking velocimetry is presented. The
aim of this integration is to provide a flexible methodology
able to analyze images with different seeding and ...
