Abstract: I develop inverse scattering methods for velocity reconstruction in the subsurface, based on multiple scattering theory, Gaussian beams and nonlinear Born approximation. This method is based ...

Abstract: Recent years have witnessed the remarkable developments made by deep learning techniques for object detection, a fundamentally challenging problem of computer vision. Nevertheless, there are ...

The ride-hailing giant’s background check process was intended to speed drivers onto its network while keeping costs down, internal documents show. The ride-hailing giant’s background check process ...
