Simrar is an analog radio receiver simulator and statistical recorder. The simulator is composed of typical analog computer components which provide versatility in simulating receiving systems. A control circuit automatically cycles the machine through a present number of statistical trials. On...

After a review of the respective merits of analog, hybrid and digital computation, the author gives an overview of the most recent developments in these different computing techniques. He concludes that the use of several digital minicomputers working in parallele under control of another...

A main difficulty in practical implementation of optimal control theory for distributed systems lies in the computational complexity, especially in presence of constraints.

On présente un simulateur daps lequel les artères et les veines sont représentées directement par des ensembles de résistances, de selfs et de capacites contrôlées de façon spécifique. On simule en outre les artérioles, les capillaries et le ventricule gauche. Quelques résultats sont...

In this paper, parameter sweep problem in iterative analog computing techniques is studied. Some new method, completely automatic, for parameter sweep study is developed. The method possesses a great flexibility and gives good results, regardless of the mathematical model of the system (linear...

This paper presents a tutorial analysis of a hybrid computer model of a missile reentering the atmosphere.

After discussing the already-known means for solving optimization problems by the maximum gradient principle, this paper then contributes several modifications to this method which permit solution by analog iteration of a large number of problems comprising several variables; including those...

A computing method is described based on a level-control yielding the numerical solution of a two-point boundary-value problem as the periodic steady-state solution of a corresponding initial-value problem.
