[SwarmFest2004] paper

Dear Professor,

In this time we have a paper entitle "Particle swarm optimization techniques for depth determinations from gravity data" (enclosed you can find the abstract), Please let us know if there is a possibility to submit the paper in the

SwarmFest 2004
conference, In all cases we are sorry for the dealy.

Best wishes

1. Abstract

The present paper deals with a swarm intelligent technique to determine the depth of a buried structure from its residual gravity anomaly. The problem of depth determination can be transformed into a problem of finding a solution of non-linear equation . The Particle swarm optimization (PSO) technique is applied to simple geometric models such a sphere, vertical and horizontal cylinders and for a vertical fault with and without random noise. Finally, a field example is presented in which the depth to a fault is estimated at 3.8 km and verified from drilling results.
