Three-Dimensional Inverse Scattering,time-independent Schrodinger equation [Δ + h.?V(x)]φ(k,x) = 0 is summarized. It is most easily understood by considering the associated hyperbolic equation [Δ ?a. ? V(x)]u(t,x) = 0. Particular attention is paid to those aspects of the theory that hold for the wave equation [Δ ? n.

Parameter Estimation for Distributed Systems Arising in Fluid Flow Problems via Time Series Methodses is very complex. The difficulties arising from multiphase flow problems are even more severe. There are many different sources of error in the modeling process which lead to the distributed parameter systems and their computer solution.
