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
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 ...
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 ...
Using Detrended Cross-Correlation Analysis in geophysical data
(Physica A: Statistical Mechanics and its Applications, 2013)
Improving the shape of the cross-correlation function for leak detection in a plastic water distribution pipe using acoustic signals
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 ...
Exact crossing rates of dual diversity over unbalanced correlated Rayleigh channels
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2006)
Integrating cross-correlation and relaxation algorithms for particle tracking velocimetry
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 ...
