The research result shows the location accuracy by the method is better and improves more than original location result in residual error, evaluated error, epicenter distribution and focal depth.

Have you ever used ranged based conditional formatting (such as icon sets, color scales and data bars) only to find that one of your formulas have evaluated to an error?

A modified adaptive model following control algorithm was presented, in which the system output error is added to control signal and the next time output error is evaluated by linear networks.
