Perot's running mate, retired admiral James Stockdale, was likable but a non-factor, and his performance took a little steam out of the momentum Perot had gained after the St. Louis debate.

The actual prediction ability of BP network model is improved and training velocity is increased by adding momentum factor and using the weight control calculation in the BP network model.

We conclude that the horizontal center of meson charge density distribution is related to the form factor at large momentum transfer. We give a general conclusion.
