**Fast Transforms Algorithms, Analyses, Applications**This book has grown from notes used by the authors to instruct fast transform classes. One class was sponsored by the Training Department of Rockwell International, and another was sponsored by the Department of Electrical Engineering of The University of Texas at Arlington. Some of the material was also used in a short course sponsored by the... | | **Computer Algebra: Symbolic and Algebraic Computation (Computing Supplementa)**
The journal Computing has established a series of supplement volumes the fourth
of which appears this year. Its purpose is to provide a coherent presentation of a
new topic in a single volume. The previous subjects were Computer Arithmetic
1977, Fundamentals of Numerical Computation 1980, and Parallel Processes and
Related Automata... | | **Symmetry**STARTING from the somewhat vague notion of symmetry = harmony of proportions, these four lectures gradually develop first the geometric concept of symmetry in its several forms, as bilateral, translatory, rotational, ornamental and crystallographic symmetry, etc., and finally rise to the general idea underlying all these special forms, namely that... |
