[20070901] Localized imagedifference waveequation tomography The geophysical inversion technique presented in this paper allows a reduction of the largescale optimization problem arising in both imagedifference wave equation tomography and waveequation velocity analysis into a series of smaller optimization tasks than lend themselves to efficient solving using existing techniques such as limitedmemory BFGS (LBFGS) quasiNewton method, conjugategradients, etc.

[20070429] Pipeline Hydraulics Simulator
The referenced paper (save the thumbnailed link on the left pane as a .pdf file) presents a mathematical model of a steadystate operation of a hydrocarbon pipeline, and describes commercial computer software developed for steadystate pipeline hydraulics simulation. A project is currently under way for porting this software into a webenabled application, enhancing both its core functionality and interfaces. Project status can be tracked on the project website referenced below.

[20061120] Mathematical Model of Pipeline Cathodic Protection
The referenced article presents a mathematical model of industrystandard pipeline cathodic protection systems that provides for reliable recovery of pipeline corrosion and insulation status from the readings of a few field test potential measurements.

[20061008] Geophysics  Wave Equation Migration Velocity Analysis Check out the following publication on a new proposed technique for Wave Equation Migration Velocity Analysis. An overview of nonproprietary mathematical methods of velocity analysis will be presented at the Applied and Industrial Mathematics Seminar (see the Education Section)

[20060710] Marmousi Velocity Model
Marmousi Velocity Model is a synthetic velocity model produced by the French Petroleum Institute and released to general public with the purpose of providing a complex velocity model that can be used for testing the efficiency of migration and velocity analysis algorithms.
Here we present a Fortran programme that transfers hard and smooth Marmousi velocity models into a BP FreeDDS dataset.
