Interest in optical information processing stems from the never-ending effort to increase data handling capacity and to improve the interface with human senses. The manipulation of two-dimensional data in an image format and processing in a parallel organized integral transform distinguishes the optical analog computer from its counterpart---the electronic digital computer processing one-dimensional data in a sequential manner. The optical analog computer is admirably suited to performing linear operations such as matrix products, Fourier transform integration, and related correlations and convolutions. The photographic plate is usually employed as the input, memory, control function, and output to demonstrate optical information processing concepts.

A card punch traditionally has been looked upon as a machine which is composed of many complex and ingenious mechanisms because of the complex task that it must perform. Complex mechanisms, however, have an ingenious way of making noise, being unreliable and difficult to service.

Implementing a compiler, as everybody knows, is not an easy task. There have appeared in the past few years a number of compiler writing systems. One of these is Feldman's "Formal Semantic Language" (FSL). In Feldman's thesis the assertion is made that FSL is potentially a powerful compiler writing system. The Formula Algol compiler is a large, nontrivial compiler incorporating several new language features, and the use of FSL to implement it constitutes the first significant test of the power of FSL. We find Feldman's assertion is justified, and the ideas he set forth in theory have been found to be successful in practice.

The capability for combined analog-digital computation at the United Aircraft Research Laboratories was greatly expanded in January 1966 by the addition of a large-scale, time-shared, general-purpose digital computer and a pool of hybrid linkage equipment which can be distributed to any of four analog consoles. The digital computer timesharing system provides hardware and software for the simultaneous use of the system by several users at teletype consoles.

In recent years digital computers have been applied, with great success, to the automation of an increasing variety of tasks in the design of digital systems, from the printing of wiring tables and the drawing of logical diagrams to the optimization, according to certain criteria, of the layout of components and wiring, and even the actual computer-controlled production of subassemblies such as printed circuit boards or integrated circuits. Similarly, the design of circuits, especially those involving nonlinear elements, has been made easier by computer programs (e.g., which perform tolerance analyses). On the system level, the use of digital computers has been limited to tasks which are equally mechanical, such as programs which check for violations of fan-in, fan-out, and cascading rules.

Core transient neutron flux distribution currently constitutes one of the most intensively investigated phenomena in nuclear technology. Independently, nuclear physicists and system analysts attempt to develop solutions to the problem. The arsenal of mathematical tools presently available to them covers most of the spectrum ranging from precise multigroup digital computations to adiabatic core analog analysis. The former involve a series of steady state or quasi-steady state situations, hence are not acceptable to the transient analyst. The latter are too inadequate for detailed safeguard or control analysis, thus forcing the designer to increase his conservative margin.

Ten years ago IBM announced the 305 and 650 RAMAC Data Processing Systems---systems that heralded the on-line processing concept, wherein business transactions could be economically processed as they occurred. This was made possible largely through the use of the 350/355 Disk Storage Files, whose 5 million stored characters were directly accessible. Since that time, significant advancements have been made in direct-access memory development. These include the double density 350/355, the 1405, the 1301 and the 2302. Pioneering the removability and interchangeability features of direct-access storage media was the 1311 Disk Storage Drive. A further advancement is the 2321 Data Cell Drive.

The study of dynamical systems with the aid of analog and digital computers has developed rapidly in the past two decades. Increased interest in systems described by differential equations which are nonlinear or have time-varying coefficients, has resulted in more reliance on techniques requiring on-line computation. Usually less is known a priori of how the solutions will develop or what parameter values or initial conditions should be used. The recent trend to using hybrid computers (combinations of digital and analog equipment) has been motivated by the desire to study complex dynamical systems with computer configurations which are designed with particular classes of problems in mind. Extensive use of display, plotting, and printing equipment as well as elaborate consoles attest the on-line capability of such computers.

The Large Aperture Seismic Array (LASA) consists of 525 vertical motion seismometers installed in an area of approximately 10,000 square miles in eastern Montana. Each seismometer is located at the bottom of a 200-foot borehole to reduce noise generated by wind, traffic, and livestock. The seismometers are grouped in clusters (subarrays) of 25 seismometers each, and the 21 subarrays are arranged in a series of successively inscribed squares (see Fig. 1) to produce a logarithmic density taper.
