It has been our experience in the Air Materiel Command, and I imagine this is true of everyone engaged in data systems modernization and automation, that the further we advance, the greater potential we find for achievement. A prime characteristic of ...

In the field of computing machinery there is an ever-increasing demand for the development of random-access digital memory-storage units that operate at higher speeds and provide greater storage capacities. In 1951 a digital memory-storage unit that had ...

This is the second in a series of papers concerned with a technique for performing combinatorial and sequential digital logic with magnetic elements and connecting wires only. These elements are termed MAD's (Multi-Aperture Devices). For clarity, in the ...

A new magnetic matrix memory has been developed for the storage of semipermanent digital information. The memory is designed for computers which require random access to stored information that is changed very infrequently. The information is stored in ...

With the steady increase in the required speed and complexity of computing and data processing equipment necessary to handle today's problems, the role of the associated storage systems has been expanding. Generally, a rather large amount of permanent ...

Ferrites, ferroelectric capacitors, and some ferromagnetic materials all possess bulk characteristics which are usually referred to as square-loop properties. It has been recognized for some time that these properties are particularly compatible with ...

Increasing attention to automatic information processing is being given by all sections of our technology, commerce, and military operations. One of its more important aspects is the use of computing machines for storage and subsequent retrieval of ...

The need for mechanizing library information searches has become apparent during the past two decades. The phenomenal increase in the size and number of library establishments in conjunction with the requirement for greater speed in servicing ...

Two conditions have made it almost inevitable that we have an information-retrieval project at the System Development Corporation (SDC). First, our internal documentation. It has been estimated that we acquire 10,000 documents a year both from internal ...

The mathematical formula which best describes my conclusions from reading the literature on information retrieval (IR) is the following:

4 U OK 4 $ = ET

For you, better for dollar equality.

The United States Air Force has numerous and varied types of data handling problems. This paper reviews some of the developmental approaches and contributions that the Air Force has made toward the solution of semantic-graphic information handling ...

To distinguish himself from the poor benighted man-in-the-street, the computer sophisticate is apt to refer to the beasts as "so-called giant brains" or as "lightning-fast idiots." He knows, as do we, the great gulf which separates the human brain from ...

The graphic arts laboratory of Time Inc. in Springdale, Conn., is a laboratory largely devoted to improving the arts of printing and paper-making. Of equal importance to a publisher of weekly news magazines is a large and well-serviced list of ...

This discussion concerns a mechanized information retrieval system for the technical library of General Electric's Aircraft Gas Turbine Division. The system is confined to the technical reports and papers available in the Division's Library. Textbooks ...

Although information retrieval has lately become quite a fad, I intend in this paper to stand back and take an unhurried look at what is going on, and try to predict where this field must go and what it must do in the future. "Information retrieval" is ...

Expressions for the probabilities of multiple error patterns in symbols consisting of N bits are needed to evaluate the effectiveness of applying error correcting codes to these information channels. For example, if a Hamming single error correcting ...

Analog computation is, for many problems, more convenient than digital computation but lacks the precision obtainable from a digital-computer solution. A compiler has been developed which, for problems involving differential equations expressible in the ...

The frequent use of transcendental functions in digital computer programs has presented a basic problem in the design of real-time control systems. Since there are usually no single instructions to perform such functions as sine x, arc sine x, etc., two ...

Along with the increasing availability of high-speed, large-storage digital computers, there has been growing interest in their utilization for real-time control purposes. A typical problem in this connection and one of long-standing interest is the ...

Simulating human problem-solving on a digital computer looks deceptively simple. All one must do is program computers to solve problems in such a manner that the computer employs the identical strategies and tactics that humans do. This will probably ...

Since the Fall of 1956, the author has been studying the genesis and operation of university programs in the fields of computers, data processing, operations research, and other relatively new and apparently closely related fields. The specific purposes ...

Current techniques in automatic coding attempt to shift the user's tasks away from the computer and closer to his application. Sacrificing coding details in this way, it is believed that monumental savings will result both in computer acceptability and ...

The preparation of a program for a digital computer is not complete when a list of instructions has been written. It still must be determined that the instructions do the required job, and if necessary the instructions must be changed until they do. ...

We would like to consider a new approach to the general problem of programming computers. To date, the methods of handling programming problems can be roughly classified into two families, each of which have certain characteristic advantages and ...

The concept that any "standard" electronic data processing or computing system should be adapted solely through programming to suit a particular business or industry is no longer supportable, except as an interim step for testing the planning and design ...

In this paper we develop and investigate the properrties of a novel system, called the residue code or residue number system. The residue number system is of particular interest because the arithmetic operations of addition and multiplication may be ...

Testing and instrumentation are essential pre-requisites for the completion and operation of any new system. A system can be defined as a number of components that are amalgamated or integrated together to perform a desired operation. Throughout this ...

Perfect reliability in digital computers has not yet been achieved by simply designing ruggedness into the equipment components. Nevertheless, it is essential for a computer to perform dependably under all conditions. In certain computer applications, ...

This paper describes a data translator which, when used with a digital computer, permits simulation of speech- and television-processing devices. The usual function of such devices is to realize efficient codings of information-bearing signals thereby ...

Ever since the development of automatic sequence computers it has been possible for the machine to modify its own instructions, and this ability is the greatest single faculty in the complex that tempts the term "giant brain." Friedberg demonstrated a ...
