Software

Available

QRfit: a flexible utility for time series decomposition.
Get version 2.0 rpm or src.
QRfit requires the Gnu Scientific Library available here as an rpm or from the gsl website.

Math::Random::Brownian: A Perl module for generating Brownian Motion and fractional Gaussian Noise.
Get version 0.03 (stable) here or CPAN.

Coming Soon

Geo::Deform: A Perl module to calculate internal deformation due to shear and tensile faults in a half-space using Y. Okada's closed analytic expressions.

Erdös Number

With the acceptance of Young and Szeliga, 2005, I have obtained an Erdös number. For more information about Erdös numbers I suggest The Erdös Number Project. An Erdös number is the co- authorship distance between a particular person and Paul Erdös. Paul Erdös's Erdös number is 0, and by the chains of co- authorship below I have an Erdös number of 6. Here are two co- authorship chains,

Paul Erdös ⇐ Jean Marc Deshouiller ⇐ Ralph S. Phillips ⇐ Peter Lax ⇐ James Glimm ⇐ Robin Young ⇐Walter Szeliga

Paul Erdös ⇐ Fan Rong K. Chung ⇐ Shing-Tung Yau ⇐ Joel Alan Smoller ⇐ Blake Temple ⇐ Robin Young ⇐ Walter Szeliga
