Beamlet Migration Based on Local Perturbation Theory
نویسندگان
چکیده
Beamlet migration based on local perturbation theory is proposed. The method is formulated with a local background velocity and local perturbations for each window of the wave eld decomposition using Gabor-Daubechies frame and local cosine basis. The prop-agators and phase-correction operators are obtained analytically for the G-D tight-frame, and numerically for the local cosine basis. The numerical test using the SEG-EAEG salt model poststack data demonstrates the great potential of this approach.

Study of the influence of propagator amplitude correction on image amplitude using beamlet propagator with local WKBJ approximation
Localized WKBJ correction based on Local Cosine Basis (LCB) beamlet propagator is applied in postand pre-stack migration to study its influence on image amplitude. 2D SEG/EAGE salt model is used for demonstration. The results indicate that localized WKBJ correction have some improvement on the image amplitude though not very dramatic for 2D SEG/EAGE salt data with relatively smalloffset acquisi...
متن کاملNonlinear analysis of radially functionally graded hyperelastic cylindrical shells with axially-varying thickness and non-uniform pressure loads based on perturbation theory
In this study, nonlinear analysis for thick cylindrical pressure vessels with arbitrary variable thickness made of hyperelastic functionally graded material properties in nearly incompressible state and clamped boundary conditions under non-uniform pressure loading is presented. Thickness and pressure of the shell are considered in axial direction by arbitrary nonlinear profiles. The FG materia...

Kirchhoo migration operator is a highly oscillatory integral operator. In our primary work 1] (Wu and Yang, 1997), it has been shown that the matrix representation of Kirchhoo migration operator for homogeneous background in space-frequency domain is a dense matrix, while the compressed operator in beamlet-frequency domain, which is the wavelet decomposition of the Kirchhoo migration operator, ...
متن کاملAnalytic Equation of State for the Square-well Plus Sutherland Fluid from Perturbation Theory
Analytic expressions were derived for the compressibility factor and residual internal energy of the square-well plus Sutherland fluid. In this derivation, we used the second order Barker-Henderson perturbation theory based on the macroscopic compressibility approximation together with an analytical expression for radial distribution function of the reference hard sphere fluid. These properties...

The aim of the present study was the pathology of the migration behavior of Iranian athletes. The approach of the present study was qualitative and applied based on the pragmatism paradigm using pull-push theory (external attractions) - (internal repulsions). After library studies, 19 experts and specialists were interviewed and the factors affecting the sport migration of Iranian athletes were...
