WebA time‐varying deconvolution method has been developed which is based upon adaptive linear filtering techniques. This adaptive deconvolution is applicable for use in processing reflection seismic data which contain multiples with periods that vary with traveltime. Filter coefficients are designed for each sample of the input trace using an adaptive algorithm. … WebFor comparison, we use the traditional predictive deconvolution to squeeze all wavelets (figure 5a), the filter length N is 10 and the prewhitening factor is 0.0001. The traditional method produces a reasonable result at the high-frequency locations, however, the predictive deconvolution still loses part of the original amplitudes. grace fellowship church in buckeye azWebKamath graduated in December 2013 with a Ph.D. in Information Technology on ``Evolutionary Machine Learning Framework for Big Data Sequence Mining".

WebINTRODUCTION. Deconvolution is a filtering process which removes a wavelet from the recorded seismic trace by reversing the process of convolution. The commonest way to perform deconvolution is to design … WebThe delay time is the same as the propagation delay time of the slow Rayleigh wave and is proportional to the site of the crack. To efficiently detect the slow Rayleigh wave, three methods based on digital signal processing are proposed: wave shaping, dynamic predictive deconvolution, and dynamic predictive deconvolution combined with …

WebSeismic dynamic deconvolution is the mathematical basis on which a degree of unification in different prospecting methods is possible, relative to the parameter identification in horizontally stratified media. There is a basic structure which has some immediate applications to the inversion of resistivity data and possibly to other problems. http://eceweb1.rutgers.edu/~orfanidi/aosp/

WebPredictive deconvolution The problem is now to estimate a predictive filter f with the input traces. As the input traces have 512 samples, I took the length of the filter equal to 50 samples. The residuals of L 2 and L 1 deconvolution on the pure trace are similar (Figure ). As the input wavelet is minimum-phase, the L 2 deconvolution is efficient. grace fellowship church in shrewsbury paWebThe Spectra: The UVA Undergraduate Engineering Research Journal.
