based on the convolutional model, a seismic trace is the convolution of seismic source wavelet and reflection coefficient series of the earth. seismic source wavelet estimation is one of the most important stages in processing and interpretation of seismic data. accurate estimation of wavelet increases the efficiency of the deconvolution and temporal resolution of seismic data. on the other han...

S U M M A R Y We describe a general geometric framework for thinking about source-type plots for moment tensors. We consider two fundamental examples, one where the source-type plot is on the unit sphere, and one where it is on the unit cube. The plot on the sphere is preferable to the plot on the cube: it is simpler, it embodies a more natural assumption about eigenvalue probabilities and it i...

parody as a salient device in postmodern literature is extensively applied by tom stoppard in his plays. having different layers of parody, stoppard’s “rosencrantz and guildenstern are dead”, “the real inspector hound”, and “dogg’s hamlet, cahoot’s macbeth” exhibit his parodic application of other writers’ plots. the analytical-qualitative scrutiny of the plot lines of these plays not only corr...

can be obtained. The technique is essentially a graphic one in which the function f(x) and its derivatives /' (x), /" (x), ■ ■ ■ are generated by an electronic differential analyser The method depends heavily on the ability of the analyser to produce an accurate plot of the function and its derivatives. The use of these accurate graphs is obvious for finding the real roots of the equation. But ...

s the use of 3D seismic interpretation continues to become part of the main stream work process with the industry, visualization techniques also continue to evolve as software and hardware improves. In the past 10 years, volume rendering tools have been progressively adopted by the geophysical community as the emergence of high-end graphics workstations with 3D texture capabilities made real-ti...

the improvement in the temporal resolution of seismic data is a critical issue in hydrocarbonexploration. it is important for obtaining more detailed structural and stratigraphic information. manymethods have been introduced to improve the vertical resolution of reflection seismic data. eachmethod has advantages and disadvantages which are due to the assumptions and theories governingtheir issu...

By using the method of the visibility graph (VG) the synthetic seismicity generated by a simple stick-slip system with asperities is analysed. The stick-slip system mimics the interaction between tectonic plates, whose asperities are given by sandpapers of different granularity degrees. The VG properties of the seismic sequences have been put in relationship with the typical seismological param...
