the compact finite difference schemes have been found to give simple ways of reaching the objectives of high accuracy and low computational cost. during the past two decades, the compact schemes have been used extensively for numerical simulation of various fluid dynamics problems. these methods have also been applied for numerical solution of some prototype geophysical fluid dynamics problems ...

Cooperative inversion is a powerful underground imaging technique that can overcome the limitations of single detection method. However, due to different grid divisions used by various geophysical methodologies, imposing structural constraints between grids scales challenging. This paper proposes new cooperative strategy and applies it quasi-two-dimensional aerial transient electromagnetic meth...

The inversion of the one–dimensional Radon transform on the rotation group SO(3) is an ill posed inverse problem which applies to X–ray tomography with polycrystalline materials. This communication presents a novel approach to the numerical inversion of the one–dimensional Radon transform on SO(3). Based on a Fourier slice theorem the discrete inverse Radon transform of a function sampled on th...
