Abstract: Since subsurface structures are often anisotropic, conventional anisotropic acoustic wave equation depth migration methods are generally limited to one-way wave equations. In contrast, ...

Part 2 shows how to modify the circuit for use with higher supply voltages, implement it using discrete parts, and modify it to closely approximate a sine wave. An ongoing project (or gadget) called ...

"We could no longer use the equations of physics to predict the future from the past and present," he continued. "For these reasons, most practising scientists expect that singularities are not ...

A two-dimensional triangular mesh generator with pre- and post-processing utilities written in pure MATLAB (no toolboxes required) designed specifically to build models that solve shallow-water ...
