The four basic analogue computer operations are identified and utilized in a vector-matrix format for the computer equations. This format, which is reminiscent of the state equation model for a dynamical system, displays clearly the task of analogue computer programming and scaling for a given...

A non-linear digital simulator for BWR nuclear powre plants and the digital code LIMBO based on this model will be derived. Comparative calculations to start-up tests at a large BWR nuclear power plant will demonstrate the efficiency of the code. Its application within the concept of linear...

Cet article décrit un procédé automatique itératif pour l'optimalisation de la portée d'un rayon ionique, sur calculateur analogique conventionnel.

This article describes a simple circuit for the measure of the period of slow functions determination through an independent control integrator, whose result can be used with enough precision in both hybrid and analogical simulation.

Simple computer unit groups are used to test the performance of an analog computer by operating the units in a typical and relevant circuit. The performance is evaluated by absolute and relative observation of the generated group responses. The basis for the test program is the generation of...

The optimal adjustment of a diode function generator to a given arbitrary function, requires the definition of the slope-values of the best broken line approximation and the setting of the breakpoints.

The formula for estimating the operational amplifier error in the state is given in this paper. The maximum relative error in the steady state is shown to be inversely proportional to the pulsation at which the open loop gain frequency characteristic crosses the odb axis.

In the present paper, we shall develop the analog simulation of electric systems involving saturable core coils.
