It is our desire at the Carnegie-Mellon University Computation Center to provide to the university community a general-purpose computer utility capable of supporting the wide range of academic and research programs which are currently being advanced. In ...

As the uses of computers increase, every facility eventually becomes faced with the need to increase capacity. The solutions normally used are to replace the equipment with newer and faster models or obtain additional independent systems. The latter ...

When a general-purpose computer performs compute-limited applications, its performance—unit cost per computation—is the primary measure of its adequacy. When such a computer performs a wide variety of services—interactive computation, fast-turnaround ...

Project Intrex (information transfer experiments) is a program of research and experimentation directed toward the functional design of new library services that might become operational at the Massachusetts Institute of Technology and elsewhere in the ...

Contour maps have many engineering applications. Besides the common use of contour maps to represent elevation of a geographic region, they are frequently used to represent different types of weather information. Examples are isobars to connect points ...

This paper describes BARONET, an experimental program for page-oriented storage and retrieval of information at multiple remote display (CRT) terminals.

Two major objectives determined the structure of the system:

a. It was to be easily usable by ...

The problem under consideration here is to solve the system of linear equations Ax=b in the sense of Chebyshev. The matrix A is m × n with rank n and n+1≤ m. Define

As shown by the ACM Symposium on Interactive Systems for Experimental Applied Mathematics (held in conjunction with the 1967 National Conference), the subject of experimental mathematics is. a timely one. The author's propose in this paper to discuss ...

In several recent papers the present authors have introduced some new nonlinear transformations which are useful in numerical evaluation of improper integrals of the first kind.^1,2,3 A question which naturally arises is, to what extent are these ...

Consider an involved function f(x) which is to be approximated in the interval (α,β) by the rational function h (a, c, x):

[equation]

To determine h (a, c, x) we need to find the values of the unknown coefficients a_j and c_j. The minimax or Chebyshev ...

Interactive use of computers in instruction is increasing rapidly. Many manufacturers are promoting programming languages for educational applications of their equipment, and some are marketing small machines with software exclusively for instructional ...

In the summer of 1967 a project was begun at The University of Michigan to provide users of a general- purpose, time-sharing system with the capability for exploring conversational uses of computers for instruction. The idea for the project developed ...

In this paper we discuss a computer program which assists authors in producing computer-assisted instruction courses. The courses are executable computer programs. The course generator, CG-1, is an interactive program which produces a course program as ...

Glowing predictions on the future of education in the USA usually emphasize the expanding role that computer-assisted instruction (CAI) will have on a school or university system. It is expected that the use of computers for instructional purposes will ...

Across the nation, local governments of suburban communities surrounding major central cities are facing several basic problems: (1) a tremendous explosion in the development of land that is creating chaos in the record keeping and handling systems of ...

The need for State and Local Information Systems stems from intuitive feelings that decision-makers, researchers, and planners require more accessible and timely information. Yet, there is little general agreement as to the general nature of information ...

In recent years; it has become increasingly clear that there is need for a content-addressable computer memory. Larger and larger programs are being written which require a structured data base to operate with any efficiency. Many of these could well ...

Various approaches have been employed in the design of question-answering systems with natural language input. An excellent survey of such systems can be found in Simmons.¹ A more recent and critical survey of data-retrieval systems prepared by Kasher ...

For the purpose of this paper, a question-answering system is a computer program that has at least the following three characteristics:

(1) The ability to accept statements of fact and store them in its memory

(2) The ability to search stored ...

Many investigators have made use of syntactic analysis of figures for pattern recognition purposes during the recent years. Also a general theory of pattern analysis has been formulated recently be Grenander. Most of the earlier investigators ...

There are a number of different philosophies concerning the problems of pricing the resources of a multi-access computer utility. Although some have been proposed only academically, others have actually been implemented by the various fledgling systems ...

Substantial problems are posed in the “computer utility” industry, particularly concerning possible large scale entry by communications common carriers. On the other hand, considerable excitement has been generated by the “computer utility” concept. By ...

A technique for partitioning logic into groups having minimal interconnection was considered an important tool necessary to the building of the Univac @@@@ 9200 System. Not only would costs be reduced by minimization of the total number of printed ...

The tedious burden upon engineering personnel (logicians) who are involved in digital design has grown to enormous proportions. One of the more significant factors that contributes to this burden has been the introduction of the integrated circuit which ...

One very profitable application of computer aided design is in the design and construction of digitial computers. ¹ A classical problem in computer design is that associated with the simplification of Boolean switching expressions. Numerous algorithms ...

The representation of system characteristics by a discrete time model poses a fundamental problem in the field of digital simulation. In the majority of circumstances the problem consists of approximating a continuous time model well-defined in terms of ...

Digital simulation is a valuable tool in the evaluation and design verification of tactical computer systems. Tactical systems are characterized not only by their use in the field, but by their design as dedicated real-time systems. Because of the ...
