Automata, formal languages abstract switching, and computability in a Ph.D. computer science program
A number of courses are listed in the area described as automata, formal languages, abstract switching, and computability, that might be available to a Ph.D. student in…
Storage organization in programming systems
The system of program and data representation that has been in use on the Rice University computer for five years is described. Each logical entity in storage occupies a…
Extensive software problems confront an organization which possesses a number of different computers and which frequently acquire new ones. To maintain cohesion, a system…
A note on a relevance estimate and its improvement
In this paper the effect of iterating the improvement procedure is examined. It is shown that applications of the improvement factor beyond the first time are…
One-line random number generators and their use in combinations
Some one-line random number generators, i.e. generators requiring a single FORTRAN instruction are discussed, and some short FORTRAN programs which mix several such…
Approximate solution of initial-boundary wave equation problems by boundary-value techniques
A new boundary-value technique is proposed for the treatment of initial-boundary-value problems for linear and mildly non-linear wave equations. Several illustrative…
Theoretical and practical values of error coefficients useful in bounding the error in integrating periodic analytic functions with the trapezoidal rule are tabulated for…

Algorithms: Algorithm 338: algol procedures for the fast Fourier transform
The following procedures are based on the Cooley-Tukey algorithm [1] for computing the finite Fourier transform of a complex data vector; the dimension of the data vector…
Correspondences of 8-bit and Hollerith codes for computer environments—a USASI tutorial
The correspondence tables in the document reflect USASCII standard code assignments as well as other codes. Comments that refer to the assignments of characters or…
