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, ...
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
(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 ...
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 ...
Analysis of the nonlinear relationship between commodity prices in the last two decades
(Springer, 2014-10)
We propose the construction of a network to study the correlation among price indices of different commodities, by using the Multifractal Cross-Correlation method proposed by Podobnik and Stanley. This estimator, based on ...
Characterization of the Genetic Variability of a Sugarcane Commercial Cross Through Yield Components and Quality Parameters
(2012-06-01)
The phenotypic characterization as well as the knowledge of the correlation among traits, is the first step to quantify the potential of a cross for further QTL (quantitative trait loci) detection. The present work aimed ...

Pitch detection algorithms based on zero-cross rate and autocorrelation function for musical notes
(2008-09-22)
This paper discusses two pitch detection algorithms (PDA) for simple audio signals which are based on zero-cross rate (ZCR) and autocorrelation function (ACF). As it is well known, pitch detection methods based on ZCR and ...
