Several papers present possible mechanisms for the cardiac action potential. The more suitable models are based on the Hodgkin and Huxley ionic theory with some modifications. In this paper, hybrid computation techniques are utilized to elaborate a different model applicable to Purkinje's...

The interconnection of dynamo-electric machines and analytic computers yields interesting and useful properties not available from either of the devices singly. Moreover, the homogeneity between Kron's modern matric-mathematical description of dynamo-electric machines on the one hand, and the...

In this paper a simulation model for a basic solar heating system which is suitable for control and optimization studies is developed. A model for flat plate solar collectors using fluids for the heat transfer which allows the analysis of operation in great detail is presented. The simulation...

This paper gives the theoretical basis of a method allowing one to design a variable delay simulator using analogue computer elements. It is shown that, if conventional methods of approximation of a constant delay are extrapolated to time-dependant delays by simply making the coefficients become...

A decision evaluation and conflict resolution system is being developed for eventual use by planning and policy making organizations. The system is being implemented on a portable interactive graphic computer system. The system features the capability of integrating societal system models with...

In this paper the author examines whether it is possible to determine, with the aid of an analogue computer, simulating a system the best method to locate automatically the optimum value, provided such a value exists, of a parameter influencing in an undetermined way the behaviour of this system.

The paper refers to a mathematical model for a single species population growth, when significant hereditary influences are taken into account. The solution for the nonlinear equation is obtained via optimal control theory from the solution of a linear equation. The method is subject to many...

The demagnetizing field due to magnetization prescribed on a set of Cartesian mesh points in a flat film is solved by means of the Fast Fourier Transform (FFT). First, the magnetization and the magnetostatic potential are Fourier transformed over planes parallel to the film. Integration of the...
