I have extended the concept of localised optimisation previously used in the localised image-difference wave-equation tomography (see the Technology section) to apply to the wave-equation migration velocity analysis. Click on the thumbnail to get a larger picture of the Marmousi velocity model reconstructed from pres-stack synthetic data using the proposed technique.

Click on the thumbnail in the left pane to see animated snapshots of sample output from my time-domain wave equation modelling programme that implements my latest absorbing boundary conditions technique. The proposed technique allows for a computationally efficient numeric solution of Cauchy problems, and in terms of computational complexity it rivals existing techniques such as Perfectly Matched Layers. The method can have a broad range of applications to modelling wave phenomena in Physics and Engineering.

The Industrial Controller Project has reached an important milestone: a customised bare-bones SSH server has been implemented that supports eToken-based identification to run under Debian for ARM. This allows a wide variety of practical applications of the device in secure data exchange.

I suspend the regular sessions of the Industrial and Applied Mathematics Seminar till the 8th of January 2008. Extraordinary sessions of the seminar may be convened sooner -- please track regular announcements on this site.

Season's Greetings and Happy New Year!
