| 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. |
