Block row recursive least squares migration
Nasser Kazemi, Mauricio Sacchi
Recursive estimates of large systems of equations in the context of least squares fitting is a common practice in different fields of study. For example, recursive adaptive filteri…
Statics Preserving Sparse Radon Transform
Nasser Kazemi
This paper develops a Statics Preserving Sparse Radon transform (SPSR) algorithm.The de-coloration power of Radon basis functions depends on different factors. The most important o…
Application of shifted-Laplace preconditioners for heterogenous Helmholtz equation- part 2: Full waveform inversion
Nasser Kazemi
Seismic waves bring information from the physical properties of the earth to the surface. Full waveform inversion (FWI) is a local optimization technique which tries to invert the…
Application of shifted-Laplace preconditioners for heterogenous Helmholtz equation- part 1: Data modelling
Nasser Kazemi
In several geophysical applications, such as full waveform inversion and data modelling, we are facing the solution of inhomogeneous Helmholtz equation. The difficulties of solving…
