Greetings. See my page introduction if you are interested. The prettiest pictures here are my favorite fractal creations. The fractal animations are also nice. Full mathematical details are available through the links below.

Here are some papers I have written.

• Control of mutually exclusive user memory and execution formats giving illusion of simultaneous execution
• Mouse With Pocket
• Invocation and return of 1st-level adjunct program from a live 2nd-level system.
• Method for paring archived data to allow for smooth depreciation
• Script-driven test tool with variable hierarchical output in HTML format
• Automatically Generated, Perceptually Smooth Fractal Movie
• Auto-Generating Fractal Movie
• Method for finding geometrically similar fractal confined to fixed region
• Senile Depth First Search applied to Iterated Function Systems
• Method for scaling fractal for display by finding upper bound on extent
• Introduction to Data Compression for IE's
• Two Fractal Models for Operations Research
• Optimization on a Fractal Feasible Region
• Image Enhancement by Multiplication of 2-D Cosine Transform Coefficients
• Method of sorting dates and times allowing for wrapping
• Host-based Initiation and Analysis of PC-driven Tests

I have degrees in three different subjects from three different schools. The most recent is an M.S. in Math from Georgia Tech. I don't get to use math in my work nearly as much as I'd like, so I look for applications in everyday life. Here are some examples.

• Exploding satellites orbiting a black hole
• Fiddle lessons
• Throwing rocks off bridges
• Psychological Experiment
• How fast could I run a marathon?
• How fast could you run a marathon?
• Looking at the inside of the sun
• How long do I have?

Several of my packages are in the VM Download Library :

• CP1STLVL is a CP exit for second-level VM systems. It allows second-level users to invoke first-level commands without pausing the second-level system. It's handy in my software testing.
• CPGRAB is a CP exit. I wrote it in order to grab, hold, and release certain CP locks.
• SPITABCD is a test case generation tool, generating permutations of commands in a most-useful-first order. This package also includes a REXX program for raising polynomials to integer powers, which is useful for solving a "10 men each with 3 hats" combinatorics problem.
• GETFILE is rather dated. It provided an FTP-like function.
• OBFUSCAT is a tool to help you customize the way people surf into and through your VM-based web site.
• CHUG is a tool we use in testing VM. Every night, CHUG generates hundreds of HTML files showing results of thousands of tests it controls.

IBM folks may also access my Software Testing Symposium papers and tutorials on other topics on my internal page. But you can't link there unless you are inside the IBM firewall. Sorry.

If you haven't seen enough about fractals in the above links, take a look at St. Martins Press's book Fractal Horizons: The Future Use of Fractals (edited by Cliff Pickover), for which I wrote chapter 8. And after visiting all these other links, don't miss the riveting prose of my U. S. patents:

• 5,574,798 Visual presentation system which determines length of time to present each slide or transparency
• 5,642,430 Visual presentation system which determines length of time to present each slide or transparency
• 5,973,665 Temporally invasive display guide
• 5,987,466 Presenting web pages with discrete, browser-controlled complexity levels
• 6,009,429 HTML guided web tour (To try this out, take one of the online tutorials on the CMS Pipelines page.)

Around here, we like to do experimental nuclear physics...
