Wavelet analysis as a tool to characteriseand remove environmental noisefrom self-potential time series
self-potential signals wavelet analysis
2015/9/14
Multiresolution wavelet analysis of self-potential signals and rainfall levels is performed for extracting fluctuations in electrical signals, which might be addressed to meteorological variability. I...
An overview on preseismic anomalies in LF radio signals revealed in Italy by wavelet analysis
LF radio-waves wavelet seismicity precursors
2015/9/1
Since 1996, the electric field strength of the two broadcasting stations MCO (f=216 kHz, southeast France) and
CZE (f=270 kHz, Czech Republic) has been sampled every ten minutes by a receiver (AS) lo...
Wavelet analysis on adeles and pseudo-differential operators
Adeles wavelets multiresolution analysis pseudo-differential operators fractional operator
2011/8/31
Abstract: This paper is devoted to wavelet analysis on adele ring $\bA$ and the theory of pseudo-differential operators. We develop the technique which gives the possibility to generalize finite-dimen...
Wavelet analysis of corneal endothelial electrical potential difference reveals cyclic operation of the secretory mechanism
epithelial transport-electro-osmosis-electrophysiology
2011/9/2
There is evidence that the electrical potential difference of corneal endothelium (TEPD) is related electro-osmotically to fluid transport. Hence, determination of the TEPD would serve as a measure of...
Cross wavelet analysis:significance testing and pitfalls
Cross wavelet analysis significance testing pitfalls
2009/11/11
In this paper, we present a detailed evaluation of cross wavelet analysis of bivariate time series. We develop a statistical test for zero wavelet coherency based on Monte Carlo simulations. If at lea...
Atmospheric teleconnection patterns and eddy kinetic energy content:wavelet analysis
Atmospheric teleconnection patterns eddy kinetic energy content wavelet analysis
2009/11/11
In this paper, we employ a non-decimated wavelet decomposition to analyse long-term variations of the teleconnection pattern monthly indices (the North Atlantic Oscillation and the Southern Oscillatio...
Wavelet analysis in a structured clay soil using 2-D images
Wavelet analysis structured clay soil 2-D images
2009/11/3
The spatial variability of preferential pathways for water and chemical transport in a field soil, as visualized through dye infiltration experiments, was studied by applying multifractal and wavelet ...
Wavelet Analysis of the Wind Velocity and Temperature Variability in the Amazon Forest
Intermittence Temperature Wind Turbulence Amazonia Statistical Analysis
2010/10/13
We studied the turbulent interactions among vertical wind velocity and temperature time-series measured in
the Amazonian forest, during the wet season campaign of Large Biophere-Atmosphere Experiment...
Wavelet analysis on pressure stimulated currents emitted by marble samples
Wavelet analysis pressure stimulated currents marble samples
2009/12/30
This paper presents a wavelet based method of analysis of experimentally recorded weak electric signals from marble specimens which have undergone successive abrupt step loadings. Experimental results...
Statistical and Wavelet Analysis of the Solar Wind Data
Statistical and Wavelet Analysis the Solar Wind Data
2010/10/14
We perform statistical and wavelet analysis of three time series based on the solar wind velocity of the year 2000, the original time series and two filtered components. We use the Haar Wavelet Transf...
