A simulation study to predict the response of leak detectors in the CCTL (Core Components Test Loop) experiment at the Argonne National Laboratory was carried out. A mathematical model was developed for the sodium-water interaction and the subsequent distribution o f the reaction products in a...

This article deals with some methods for the determination of the eigenvalues and eigenvectors of a matrix with real elements with the help of an analog computer.

The stray capacities in the input and feedback paths of an operational amplifier, its finite bandwidth and d.c. gain effectively narrow the bandwidth of an amplifier causing amplitude and phase errors in the computer solutions. A given degree of accuracy consequently becomes more difficult to...

This paper will establish the need for an Advanced Hybrid Computing System and develop its system features. Methods to achieve high system utilization are discussed and details of their implementation in hardware and software are given. The Software System AHCSSL is a highly transportable...

A Method has been developed for obtaining Noise samples of arbitrary correlation from a single Noise Generator, without change of Spectral Density. Formulae are given for the correlation coefficients for different networks, and results measured on the PACE Analogue Computer are compared with the...

The modified-adjoint method of Laning and Battin is a convenient and practical procedure for computing the mean square output of suitable linear time-variable systems, especially in control applications. This report proposes a simplified derivation of the modified-adjoint computer setup on the...

The effects of interface errors on the hybrid computer solution of the diffusion equation in two spatial dimensions are analyzed. Two computational algorithms are considered: a discrete-space-continuous-time component sharing method and a continuous-space-discrete-time explicit/implicit method....

The method proposed in this paper uses direct approach to the control system optimization. In order to reduce variational problem to ordinary extremum problem all state and control variables are approximated by a particular from of power polynomials in which the polynomial coefficients are given...
