Computer capabilities at western european universities
This report on the author's trip to universities in Western Europe in the summer of 1966 gives brief descriptions of computing activities at each institution visited.…
FLOWTRACE, a computer program for flowcharting programs
The FLOWTRACE system produces flowcharts of programs written in “almost any” programming language. One must describe the syntax of the control statements in…
General time-varying systems error sensitivities program
The evaluation, by the propagation of variance technique, of the sensitivity of time-varying systems to initial condition and parameter errors, involves the determination…
The second Remes algorithm as originally established for polynomials, may converge or not when the approximating functions are rational. However, the few results known in…
Tensor calculations on the computer
A FORMAC program has been written which is capable of calculating various quantities of interest in tensor calculus. Using this code, Christoffel symbols have been…
Statistical computations based upon algebraically specified models
Based upon a machine-readable statistical model and related symbolic specifications, an efficient method of performing calculations for statistical models of a balanced…
In building current computer systems, we tend to break them down into “levels” of control, command and communication; in using the system, we break our…
Multiplexing of slow peripherals
The philosophy of a monitor which allows slow output devices to be multiplexed is presented.
