Are some areas of fast Fourier transforms still unclear to you? Do the notation and vocabulary seem inconsistent? Does your knowledge of their algorithmic aspects feel incomplete? The fast Fourier transform represents one of the most important advancements in scientific and engineering computing. Until now, however, treatments have been either brief, cryptic, intimidating, or not published in the open literature. Inside the FFT Black Box brings the numerous and varied ideas together in a common notational framework, clarifying vague FFT concepts.Examples and diagrams explain algorithms completely, with consistent notation. This approach connects the algorithms explicitly to the underlying mathematics. Reviews and explanations of FFT ideas taken from engineering, mathematics, and computer science journals teach the computational techniques relevant to FFT. Two appendices familiarize readers with the design and analysis of computer algorithms, as well.This volume employs a unified and systematic approach to FFT. It closes the gap between brief textbook introductions and intimidating treatments in the FFT literature. Inside the FFT Black Box provides an up-to-date, self-contained guide for learning the FFT and the multitude of ideas and computing techniques it employs.

This IMA Volume in Mathematics and its Appllcations GRAPH THEORY AND SPARSE MATRIX COMPUTATION is based on the proceedings of a workshop that was an integraI part of the 1991- 92 IMA program on "Applied Linear AIgebra." The purpose of the workshop was to bring together people who work in sparse matrix computation with those who conduct research in applied graph theory and grl:l,ph algorithms, in order to foster active cross-fertilization. We are grateful to Richard Brualdi, George Cybenko, Alan Geo~ge, Gene Golub, Mitchell Luskin, and Paul Van Dooren for planning and implementing the year-Iong program. We espeeially thank Alan George, John R. Gilbert, and Joseph W.H. Liu for organizing this workshop and editing the proceedings. The finaneial support of the National Science Foundation made the workshop possible. A vner Friedman Willard Miller. Jr. PREFACE When reality is modeled by computation, linear algebra is often the con nec- tiori between the continuous physical world and the finite algorithmic one. Usually, the more detailed the model, the bigger the matrix, the better the answer.Efficiency demands that every possible advantage be exploited: sparse structure, advanced com- puter architectures, efficient algorithms. Therefore sparse matrix computation knits together threads from linear algebra, parallei computing, data struetures, geometry, and both numerieal and discrete algorithms.

After the death of Syria’s President Hafiz al-Asad inmid-2000, hopes were high that his son and successor, Bashar, might succeed inreforming a system that had become a byword for economic stagnation and thepitiless repression of dissent. For six months, and for the first time indecades, Syrians were able to speak freely, without fear of the hated secretpolice. Political discussion groups mushroomed. The press started carryingarticles openly demanding democracy, and petitions were circulated insistingthat democracy was essential not only for its own sake but as a condition fordesperately needed investment and economic expansion.Based on the testimony of key players, Syria: Neither Bread Nor Freedom recounts the drama of the ‘DamascusSpring’ and its repression, and reveals what happens in a state like Syria tothe institutions that occupy the political space between government and governed. From political parties to parliament, from the media to the judicial system anduniversities, this book lifts the veil of rhetoric and propaganda to reveal asystem so demoralized and corrupt that power is wielded for no purpose butpower itself. This is Bashar al-Asad’s legacy and the system which, given time,he hopes to reform.
