Radial Symmetric Fourier Transforms - English
URL: http://cadcwww.dao.nrc.ca/adass/adass_proc/adass3/papers/birkinshawm/birkinshawm

Fourier transforms of radially-symmetric functions can be performed efficiently using the Hankel transform of order zero. Convolutions of radially-symmetric functions can also be performed simply. Illustrations of the method are presented, and the Gibbs' phenomenon associated with the ROSAT PSPC PRF is discussed.

NASA SPACE MATHEMATICS - English
URL: http://www.jsc.nasa.gov/er/seh/math4.html

The exploration of space naturally uses the tools and techniques of astronomy. Astronomy in turn is gaining much new information as a result of sending scientific probes and satellites beyond Earth's atmosphere. Because astronomy has stimulated the growth of many of the concepts and methods of mathematics, the high school teacher will find here much that is familiar. However, in some instances the way mathematics is used to solve real-life problems is rather different from methods emphasized in school courses.
