Using DDS Data Formats in Octave/Matlab

Save the link on the left as a .pdf file for a short demonstration of how DDS dictionaries and binaries can be manipulated in Octave and Matlab. The Free Data Dictionary System (FreeDDS) is an open-source seismic data processing system developed by BP (see references in the document)

Localized image-difference wave-equation tomography

The geophysical inversion technique presented in this paper allows a reduction of the large-scale optimization problem arising in both image-difference wave equation tomography and wave-equation velocity analysis into a series of smaller optimization tasks than lend themselves to efficient solving using existing techniques such as limited-memory BFGS (LBFGS) quasi-Newton method, conjugate-gradients, etc.

Pipeline Hydraulics Simulator

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

The original version of the software can be provided under an academic or commercial license upon request.
