Efficiency of scattering algorithm with overset grid generation for detection of buried object

The safety of building and civil structures affected by seismic waves emanating from the earthquakes has always been of concern to the general public. Post-hazard assessments must be conducted to ensure the integrity of the affected buildings, infrastructures and lands before continuing usage. Exten...
