111Cooley-Tukey FFT algorithm — The Cooley Tukey algorithm, named after J.W. Cooley and John Tukey, is the most common fast Fourier transform (FFT) algorithm. It re expresses the discrete Fourier transform (DFT) of an arbitrary composite size N = N 1 N 2 in terms of smaller… …
112Coprocessor — A coprocessor is a computer processor used to supplement the functions of the primary processor (the CPU). Operations performed by the coprocessor may be floating point arithmetic, graphics, signal processing, string processing, or encryption. By …
113Conditional (programming) — Conditional statement redirects here. For the general concept in logic, see Material conditional. In computer science, conditional statements, conditional expressions and conditional constructs are features of a programming language which perform …
114Wallace John Eckert — (June 19, 1902 ndash; August 24, 1971) was an astronomer, and Director of the Thomas J. Watson Astronomical Computing Bureau at Columbia University. In January 1940, Eckert published Punched Card Methods in Scientific Computation , which solved… …
115Volume rendering — is a technique used to display a 2D projection of a 3D discretely sampled data set.A typical 3D data set is a group of 2D slice images acquired by a CT or MRI scanner.Usually these are acquired in a regular pattern (e.g., one slice every… …
116Actor model and process calculi — In computer science, the Actor model and process calculi are two closely related approaches to the modelling of concurrent digital computation. See Actor model and process calculi history.There are many similarities between the two approaches,… …
117Dovetailing (computer science) — Dovetailing in algorithm design, is a technique that interleaves different computations, performing them essentially simultaneously. Algorithms that use dovetailing are sometimes referred to as dovetailers. Consider a tree that potentially… …
118BrookGPU — is the Stanford University Graphics group s compiler and runtime implementation of the Brook stream programming language for using modern graphics hardware for non graphical, or general purpose computations. Use of Graphics Processing Unit (or… …
119Chemical computer — A chemical computer, also called reaction diffusion computer, BZ computer (stands for Belousov–Zhabotinsky computer) or gooware computer is an unconventional computer based on a semi solid chemical soup where data is represented by varying… …
120Switch-technology — is a technology for automata based programming support. It was proposed by Anatoly Shalyto in 1991. It involves software specification, design, implementation, debugging, documentation and maintenance. The term “automata based programming” is… …
