1955 Proceeding- Conference Chair:
- William L. Martin
The western Joint Computer Conference has greatly increased in size since the first meeting held in February of 1953. Membership actually has doubled. In 1955 there were 1,490 registrations as compared with 732 in 1953.
The technical programs have always been designed to present material on both analog and digital machines. When possible, field trips to manufacturers and installations have been included in the Conference, as was done in 1955. This year 36 manufacturers exhibited products, as compared with 22 in 1953.
These statistics indicate increasing interest on the part of manufacturers, users, and potential users of the type of automatic data processing equipment discussed. The Conference has changed in character from a meeting of small groups of specialists discussing problems of mutual interest to large meetings involving people from many phases of engineering, management, business control.
These Proceedings now are becoming of interest to an increasingly wider spectrum of society.

Transfer-function synthesis with computer amplifiers and passive networks
The study of dynamic systems on an analog computer often involves the synthesis of complex transfer functions. Techniques from the field of network synthesis are combined with methods used in electronic-differential-analyzer work to provide effective ...
Simulation by modeling
Simulation by modeling may be classified into three related methods.
1. We may use analog models which obey the same laws as the phenomena we wish to study. Instruments such as network analyzers, slide rules, and electrolytic tanks are examples of ...
Ideal transformers in the synthesis of analog computer circuits
The need for ideal transformers in the solution of network synthesis problems, especially in multi-terminal problems, has long been recognized. Nevertheless, there has been a general feeling that solutions to synthesis problems containing ideal ...
A new approach to grounding in DC analog computers
The difficulty of minimizing ground current effects and the problems caused by offset voltages in the development of dc analog computers is presented. A conventional grounding system is discussed and a ground isolation system is disclosed as a means of ...
The need for integration of accounting systems and the design of electronic data-processing systems
A short time ago Henry Dreyfuss, the man who designed your telephone and many other commercial products, gave an address on the principles of good industrial design. Mr. Dreyfuss emphasized his fundamental point by quoting an old Greek philosopher, who ...
Data collection as a by-product of normal business machine operation
The purpose of this paper is to explain an automatic system of collecting data on a punched paper tape as a by-product of normal business machine operation.
Computers challenge engineering education
When quantum theory was newly stirring the world of physics, an older professor was reported to have said to his graduate students studying this subject, "I don't believe you young fellows understand this stuff any better than I do, but you all stick ...
An optimization concept for business data-processing equipment
It is demonstrated that under certain conditions there exists an optimal relationship, based on cost and performance, between the number of magnetic tape units and the number of digital computers in a business data-processing system. The relationship is ...
Data-processor requirements in production and inventory control
Automatic data processing, as performed by punch card machines, has been an important tool in the business world for many years. In the field of accounting and statistical data collection, it would probably be impossible to conduct business effectively, ...
Application of data processors in production
The past year has seen the firm establishment of the large electronic computer in industry. With the delivery and use of eighteen IBM 700 series of Electronic Data Processing Machines, as well as the delivery of machines by other suppliers, the ...
The integrated use of analog and digital computing machines for aircraft dynamic load problems
This paper describes the techniques and methods used in investigating aircraft dynamic load problems such as vibration, flutter, gust loads, taxi and landing loads, based on an integration of both analog and digital facilities to provide maximum ...
A general digital computer program for static stress analysis
In a digital computer installation devoted primarily to the solution of aircraft design problems, an attempt has been made to provide the engineer, whenever possible, with programs which are general enough to be applicable to a large class of the ...
Aircraft performance studied on an electronic analog computer
Performance analysis of an airplane consists of the study of various operating characteristics and operating limits. These characteristics may be divided essentially into three major groups as follows:
1. Performance at Constant Altitudes. These include ...
Coding a general-purpose digital computer to operate as a differential analyzer
This paper describes a system of coding a general-purpose digital computer so that differential equations may be solved easily and rapidly. While originally developed for an IBM 701, the system is applicable to any of several large computers, in that at ...
Introduction to session on learning machines
The following four papers treat various levels of complexity in machine systems which exhibit learning ability. It is perhaps a misnomer to label such devices as "learning machines," since it is not the machine itself, but the program that guides the ...
Generalization of pattern recognition in a self-organizing system
A self-organizing system reported upon earlier is briefly described. Two further experiments to determine its properties have been carried out. The first demonstrates that self-organization still takes place even if the input patterns are subjected to ...
Pattern recognition and modern computers
We consider the process we call Pattern Recognition. By this we mean the extraction of the significant features of data from a background of irrelevant detail. What we are interested in is simulating this process on digital computers. We give examples ...
Programming pattern recognition
Everyone likes to speculate, and recently there has been a lot of talk about reading machines and hearing machines. We know it is possible to simulate speech. This raises lots of interesting questions such as: If the machines can speak, will they squawk ...
The chess machine: an example of dealing with a complex task by adaptation
The modern general-purpose computer can be characterized as the embodiment of a three-point philosophy: (1) There shall exist a way of computing anything computable; (2) The computer shall be so fast that it does not matter how complicated the way is; ...
Comments on session on learning machines
The speakers this morning are all imitators in the sense that the poet in Aristotle "imitates" life. But, whereas Messrs. Farley, Clark, Selfridge, and Dinneen are imitating the nervous system, Mr. Newell prefers to imitate the hierarchy of final causes ...
A new nondestructive read for magnetic cores
A simple but effective method has been developed for reading information from ferrite storage cores without destroying the information. A single ferrite core containing a small radial hole is used per stored bit. A wire is threaded through the hole and ...
The electrographic recording technique
A set of criteria for evaluating recording techniques is reviewed. Features, applications, and the basic technique of electrographic recording are discussed.
An electronic digital polynomial root extractor
Many mathematical techniques exist for factoring algebraic polynomials. Most require much computation and programming and are practical only for large machine computers. A different approach to the general problem is described. The mathematical method ...
A set of transistor circuits for asynchronous, direct-coupled computers
Extensive operating experience with the ORDVAC and the ILLIAC has demonstrated to members of the University of Illinois Computer Laboratory the advantages of computers which are direct-coupled and operate asynchronously. This paper describes a set of ...
A theorem on SPDT switching circuits
It is first demonstrated that networks of SPDT (Single Pole Double Throw) switches can be represented abstractly with a Boolean algebra in much the same way as networks of SPST (Single Pole Single Throw) switches have been treated by Shannon, provided a ...
