Over the past few years the growing complexity and costs of systems required to support space research and technology have generated a need for improving overall program management and concept evaluation techniques.

Some of the more recent areas of ...

The rapid development of computer technology and the creation of new engineering oriented languages have established that general purpose digital computers are increasingly suitable for simulation of the dynamics of large physical systems. In the ...

The mental image formed upon the first attempt to focus on a problem of the scope involved in systematizing the planning and scheduling functions of a space vehicle tracking range is truly overwhelming (Figure 1). Further investigation, however, while ...

The goal of this project is to improve the power and scope of computer routines that search for structure in a data base. IDEA (Inductive Data Exploration and Analysis) is a computer program that detects and represents inherent structure in multi-...

An important consideration in the design of programming systems for the management of large files of data is the method of treating hierarchical data (that is, data among which logical relationships exist at more than two levels). Recent systems have ...

Classification systems in the sciences usually provide an unambiguous structure of mutually exclusive, collectively exhaustive categories. The same formal structuralization, when strictly applied to the classification of technical literature for ...

The concept of a programmable word length computer has evolved through an attempt to minimize wasted storage in any fixed word length computer. Whether the computer contains six bits per word or 72 bits per word, storage is inevitably wasted when it is ...

This report presents the performance of the Supervisor System used on the Atlas Computer at Manchester University, and describes some of the changes made as a result of our experience with the system. Although the machine is used jointly by I.C.T. ...

Just over ten years ago, IBM and American Airlines undertook the development of a real-time airlines reservations system. At that time, there were several systems in use by the airlines to present “yes-no” information on seat availability and in some ...

Recent literature^1-6has summarized many of the characteristics of time-shared systems which have been or are being built for experimental or commercial application. Fortunately system designers are not waiting for a formal theory before experimenting. ...

Among the limiting factors in computer performance are the rates at which information can be transferred into and out of the memory. Obviously the effective data transfer rate depends on the characteristics of the peripheral unit (speed of data ...

This paper describes the work, presently in process, for using a monitoring machine to evaluate the Model 67 Time Sharing System.

In this paper we present an algorithm for the numerical solution of (1.1) which is quadratically convergent and requires only (N²/2 + 3N/2) function evaluations per iterative step as compared with (N² + N) evaluations for Newton's Method. Brown [1] has ...

Chebyshev series can be used not only for representing explicit functions but also for solving differential equations. Two Chebyshev methods, the selected points method and the tau method, have been described by Lanczos² for the solution of ordinary ...

Since its introduction in the early part of the nineteenth century, the theory of complex variables has played a steadily increasing role in mathematics, and in scientific research. In some fields complex algebra is used to simplify the description of a ...

This paper is intended as an introduction to some of the basic concepts of multiprogramming for readers who wish to study the more specialized literature in this field. It attempts to develop a framework for the discussion of multiprogramming which ...

Accelerated by the advent of time-sharing, on-line systems of all types have come into being during the past five years. All of these systems are designed to facilitate the interchange of information between the user and the machine. The applications to ...

For the past two years, Raytheon Space and Information Division at Sudbury, Massachusetts has been exploiting the time-sharing environment for the benefit of its scientists and engineers. At first, a single terminal was rented and tied into a remotely ...

Autodoc is a man-machine system designed to provide automated documentation capability to assist professional and secretarial personnel in carrying out their routine work assignments. The initial application is the production of user documentation. ...

This paper describes a computer program called UMPIRE that performs all the functions of an actual live referee for the game of Kriegsspiel. The program is written in LISP 1.5 for the System Development Corporation Q-32 Time-Sharing System. With slight ...

The following paper describes research that the authors are currently conducting in the development of a large, complex bank management simulation. The simulation, to be called the FDIC Bank Management Simulation, will be a computer model of commercial ...

The purpose of the study described in this paper was to develop a computer program that enables users arbitrarily to define symbols and to instruct the computer to manipulate and to operate with them on-line according to the rules of their definition. ...

The aim of the work reported here was to develop problem-solving programs which would solve non-trivial problems and make use of their experience. In all of the work published previously there is a clearly discernible trade-off between problem-solving ...

Problems of safety and efficiency in present day highway traffic systems are receiving considerable attention. Much of this attention is being focused upon the driving task. Driving an automobile encompasses extremely complex patterns of behavior ...

This paper centers on the issue of efficient use of a transportation vehicle. It focuses on the following question:

Given a vehicle of specified speed and capacity, how should it be scheduled in order to attain a high level of passenger satisfaction?

The transportation planning process is a set of analytical techniques used to forecast future transportation requirements and to evaluate proposed systems. While some of the techniques described in this paper can be used in the solution of current ...

This paper presents the computer-related implications, both on computer technology and on engineering, of solving an integrated, complex engineering problem. The discussion is based upon experience gained from a case study in which a series of ...

In the light of accelerating interest, it seems worthwhile to review both the current status of TSS and some of the predictions made three years ago. Our review will include a brief overview of system changes, a discussion in some depth of resource ...

The purpose of this paper is to describe the performance and operation of the UNIVAC 1107 computing system installed at the Andrew R. Jennings Computing Center at the Case Institute of Technology. The Center employs an open-shop type philosophy that ...

The most widespread use of computers by hospitals to date is for administrative purposes. In contrast to these essentially nonmedical uses, the Instrumentation Field Station of the United States Public Health Service and other medical groups have ...
