Q30:

Are there any special notices?

From: John de Rivaz <John@longevb.demon.co.uk> Mr Roger Bagula, publisher

of The Fractal Translight Newsletter, is seeking new articles. Write to him

for a sample copy - he is not on the Internet - and he appreciates something

for materials and postage.

NOTICE from J. C. (Clint) Sprott (SPROTT@juno.physics.wisc.edu): The

program, Chaos Data Analyzer, which I authored is a research and teaching tool

containing 14 tests for detecting hidden determinism in a seemingly random

time series of up to 16,382 points provided by the user in an ASCII data file.

Sample data files are included for model chaotic systems. When chaos is found,

calculations such as the probability distribution, power spectrum, Lyapunov

exponent, and various measures of the fractal dimension enable you to

determine properties of the system Underlying the behavior. The program can be

used to make nonlinear predictions based on a novel technique involving

singular value decomposition. The program is menu-driven, very easy to use,

and even contains an automatic mode in which all the tests are performed in

succession and the results are provided on a one-page summary.

Chaos Data Analyzer requires an IBM PC or compatible with at least 512K of

memory. A math coprocessor is recommended (but not required) to speed some of

the calculations. The program is available on 5.25 or 3.5" disk and includes a

62-page User's Manual. Chaos Data Analyzer is peer-reviewed software published

by Physics Academic Software, a cooperative Project of the American Institute

of Physics, the American Physical Society, And the American Association of

Physics Teachers.

Chaos Data Analyzer and other related programs are available from The

Academic Software Library, North Carolina State University, Box 8202, Raleigh,

NC 27695-8202, Tel: (800) 955-TASL or (919) 515-7447 or Fax: (919) 515-2682.

The price is $99.95. Add $3.50 for shipping in U.S. or $12.50 for foreign

airmail. All TASL programs come with a 30-day, money-back guarantee.
