On what does the fame of Turing rest? That he proved a theorem showing that for a general computing device -later dubbed a “Turing machine”—there existed functions which it could not compute? I doubt it. More likely it is because of the model he ...

In the spring of 1963 an ad hoc Committee on computing chaired by Wallace Givens, and reporting to the Advisory Board of SMSG, presented a number of timely recommendations. The intent of the recommendations was to extend the mathematics program to ...

The QR Algorithm was developed¹ to find the eigen - values of real or complex matrices. We shall consider it here in the context of exact arithmetic.

Sufficient conditions for convergence, listed in order of increasing strength, have been given.^1,2,3,7 ...

In our analysis of large elastic airplanes at The Boeing Company, we frequently encounter large systems of nth order differential equations. These systems are conveniently displayed in the form of “matric polynomials”. An investigation of the roots of ...

We compare a block successive overrelaxation method (BSOR) with a direct method for solving difference equations derived from fourth order elliptic partial differential equations. The direct method appears to be competitive in time and accuracy for a ...

The need to solve a set of n simultaneous nonlinear equations in n unknowns arises in many areas of science and engineering. The equations can be expressed in the form:

It will be assumed that at least one real solution exists and that the functions are ...

A number of general purpose numerical systems have been developed since the advent of time-sharing consoles. Some take the form of extensions of desk calculators, others, such as MAP¹ provide a functional ability in which many of the commands take the ...

It has long been a recognized goal of computer programming technology to permit problems to be stated in languages appropriate to the fields in which the problems exist, and to provide for the solution of such problems as stated without requiring the ...

Man's search for knowledge began in antiquity and led ultimately to the invention of the textbook. The first, a spelling book of 72 pages, was published in 1596¹. It contained spelling lessons and a smattering of arithmetic, history and a short ...

One of the classical problems in science is that of classification. It has found its principal use as an assist in organizing knowledge and pinpointing areas for further investigation. In classifying a set of items, one must take into account both the ...

Symbol manipulation is a valuable set of techniques currently available to computer users. Because many of these techniques are relatively new and have been used in a wide variety of applications, the terminology and utility of symbol manipulation are ...

This paper describes the file handling system developed and being implemented as a part of INTIPS, (INTe- grated Information Processing System) under the aegis of Rome Air Development Center. This file system addresses itself to the physical problem of ...

The best tool for coordinating a large program design project is the computer itself. The programmer is on intimate terms with the computer. He uses it to create his product, to test his product, and to change his product. If he is one of many ...

The objective of this paper is to describe an application program that is being developed for use as a data base management system. The program is identified by the acronym, GIS for Generalized Information System. The word “system” appears in its title ...

Aerospace missions have become exceedingly complex, requiring correspondingly complex vehicles in order to fulfill them and necessitating thorough analysis of the total mission/vehicle combination during the design, development, and testing phases. An ...

The broad aim of the vehicular traffic study under way at System Development Corporation is to develop some much-needed basic knowledge that can be used to provide a tool for research on freeway diamond interchanges—research promoting the improvement of ...

OPS is an interactive system designed for general use in a time-sharing environment. It includes an on-line capability for building models and running simulations. Simulation activities are scheduled, canceled, or rescheduled dynamically on an AGENDA ...

In April 1965 a remote computing terminal system was installed at the Langley Research Center in support of open shop programming. This paper describes the system and relates some of the experience gained in using and managing it. Because this system ...

As computer time-sharing systems have evolved from a research activity to an operational activity, and have increased in size and complexity, it has become clear that significant problems occur in controlling the use of such systems. These problems have ...

The real time priority scheduler reported herein evolved from a design effort to provide software aids for handling the interrupts that occur in hybrid computation. Since these interrupts are both internal and external (i.e., generated internal and ...

Many organizations have an IBM 7090 (or 7094) computing system at a centralized location. Functions performed include many repetitive, well-defined activities amenable to 7090 processing. These jobs might originate in Engineering, Research, Personnel, ...

A fitting way to begin this article would be to state that real-time systems are not designed properly; that the resulting losses are enormous; that industry does not know how to overcome this problem; but that an overall plan can do the trick. This ...

A major trend in the business world is toward more complete record keeping of business performance. The demands of government (federal, state and municipal) are ever increasing for purposes of tax evaluations. In addition, business executives are ...

The Automated Layout Design Program (ALDEP) is a tool to aid the plant designer in developing an optimum layout for organizational units (functions) within the restraints of space availability. Using this technique, the layout planner eliminates the ...

One of the major deficiencies that has been a deterrent to more effective use of computers today is the degree, or lack of it, to which basic management principles and controls have been applied by those who have, or at least share, the major ...

Frequently mathematical errors can be attributed to applying a theorem or using a formula in a situation which does not meet all the initial requirements. An obvious example would be the use of the Pythagorean theorem to compute the length of the ...

The purpose of this program is to utilize a computer for universal translation. A theoretical method for obtaining this objective was established. The problem was to determine whether or not this method would work. The program is subject to the ...

As a part of the introductory computation course at Carnegie Tech, each student is asked to debug algorithms for solving several problems using the ALGOL translator on the CDC G-21 computer system. When the student feels that he has a correctly running ...

In May, 1965, System Development Corporation (SDC) proposed to do some research to study program organization with respect to dynamic program behavior. Further, the proposal suggested that simulation techniques might be used to study the problem of ...

Since the computer operation when viewed as the execution of subroutines or instructions or logical subcommands is a discrete sequential process, its action or behavior can be predicted to a degree of certainty when sufficient knowledge is available ...
