In the pursuit of accuracy, speed and economy in the simulation of mathematical models of physical systems, analysts are continuously searching for more sophisticated mathematical techniques and computer systems. When the complexity of the mathematical models increases, their simulations on pure analog or pure digital computers are frequently cumbersome. The main reason for this is that some of the operations in mathematical model are inherently best handled either on the digital or the analog computer.

Telsim is a TELetypewriter SIMulation language designed for nonprogrammers and written for a moderate-size time-sharing system. It simulates continuous systems that can be described by a block diagram. Its input language is a natural engineering description of the boxes that comprise the diagram. The time-sharing system is offered commercially by the General Electric Company. This system uses a GE-235 computer shared by a number of remote model 33 or 35 teletypewriters. The programming language is a special version of FORTRAN II.

This paper discusses the development and current state of the art in parallel processing. The advantages and disadvantages of the various approaches are described from a pragmatic viewpoint. One that is described and discussed is a natural extension of the evolutionary approaches. This alternative covers the problems of locating, describing, controlling, and scheduling parallel processing. It is a general-purpose approach that is applicable to all types of data processing and computer configuration.

In order to assess the impact of any technological breakthroughs on the computer user, it is first necessary to understand the nature of the computer user's problem in its present context. Indeed, it is a source of considerable disappointment to some that radical improvements in technology over the past several decades have resulted in noncommensurate impact on the user. The purpose of this paper is to examine the question: "What will be the impact of integrated circuits or integrated electronics on computer architecture?" In the first part of the paper we will study the present picture of computing and show that, if no changes are made from present operating procedures, the impact will be small. In the second part of the paper, we analyze several aspects of computing to find conditions which will enlarge the impact. The final part of the paper will list a number of open problems in computing for which integrated electronics may provide a solution.

The case for the application of systems analysis and computer technology to the problems of urban management has been a "timely" and important subject for the past five years. The automation of administrative procedures appears to have been successful in the Chicago Police Department, where crime statistics, operations reports, traffic accident and citation reports, payroll, financial accounting, and automotive cost accounting are presently working components of the Chicago Police Department's data processing system.

The most common method for storing data in a binary form on photographic films has been to record each bit in terms of the presence or absence of a density in an area on the film. While in theory high-resolution materials have the inherent capacity for recording a tremendous number of bits within a given area, to a very great extent this has not been realizable because of technological difficulties. First of all, as the areas corresponding to the bits on the film are made smaller, they become more and more difficult to locate mechanically. And second, any film is bound to pick up a certain amount of dirt, and such particles can easily obscure individual bits and cause real havoc if high accuracy is required.

In planning the program design for a real-time control system, it is essential that the monitor program use an appropriate policy for scheduling work. The performance of the system will depend upon a number of things; but a wise choice of scheduling algorithm is essential.
