On the possibility of breaking the heterodyne detection quantum noise limit with cross-correlation
(Institute of Electrical and Electronics Engineers Inc., 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 ...
Detection of buried pipes using a shear wave ground surface vibration technique
(2012-12-01)
A major UK initiative, entitled 'Mapping the Underworld', is seeking to address the serious social, environmental and economic consequences arising from an inability to locate the buried utility service infrastructure ...

A major UK initiative, entitled 'Mapping the Underworld', is seeking to address the serious social, environmental and economic consequences arising from an inability to locate the buried utility service infrastructure ...
Improving the shape of the cross-correlation function for leak detection in a plastic water distribution pipe using acoustic signals
(2017-12-01)
This paper is concerned with time delay estimation for the detection of leaks in buried plastic water pipes using the cross-correlation of leak noise signals. In some circumstances the bandwidth of over which the signal ...
F region plasma density estimation at Jicamarca using the complex cross‐correlation of orthogonal polarized backscatter fields
(American Geophysical Union, 2004-06-16)
The differential‐phase method for Jicamarca F region density measurements has been modified to fit the real and imaginary components of the cross‐correlation of orthogonally polarized radar returns. The original method ...
Using Detrended Cross-Correlation Analysis in geophysical data
(Physica A: Statistical Mechanics and its Applications, 2013)
Detrended cross correlation analysis (DCCA) is used to identify and characterize correlated
data obtained in drilled oil wells. The investigation is focused on different petro-physical
measurements within the same well, ...
Evolution of multifractal cross-correlations between the Argentina MERVAL Index and international commodities prices
(Routledge Journals, Taylor & Francis Ltd, 2016-10)
We compute the auto-correlations and cross-correlations of the volatility time series of the Argentina MERVAL Index (the Buenos Aires Stock Exchange main index) and three agricultural commodities, in a multifractal context ...
Time-varying benefits of cross-asset and cross-region portfolio diversification
(2017-09-25)
The thesis uses return data on equities, bonds, commodities and real estate for the U.S., Europe, Asia and Latin America to examine diversification potentials. The analysis focuses on benefits of cross-asset and cross-region ...
