    The past and present of computer simulation are examined, and on that basis some predictions for the future are made. Deploring the analog vs digital concept fostered by some, the author stresses the complementary aspects of the two methods. Then, drawing heavily on the experience of others as well as his own, the more important improvements in simulation techniques and equipment of the past ten y... View full abstract»

    The use of controlled superconductors in analog-computer circuitry is discussed. It is shown that the operations of summation, multiplication by a constant, differentiation, integration, and multiplication of two variables may be performed by these circuits. It is pointed out that the advantages of compactness, reliability, and light weight that are inherent to the use of controlled superconductor... View full abstract»

    Several higher-order difference methods are investigated and compared for the problem of finding the natural frequencies of the lateral vibration of a beam. All of the methods considered are applicable to either digital or analog computers, although particular reference is made to the analog computer. The methods considered in most detail use the same basic central difference approximation, the va... View full abstract»

    The purpose of this paper is to discuss a method for the construction of a mathematical model of a large biological system. This method, based on Gibbs' free energy hypothesis, uses the format of mathematical programming, while the actual computation is accomplished by the method of steepest descent. The biological system chosen to exemplify the mathematical method was the respiratory function of ... View full abstract»

  • An Infinite-Resolution Function Generator

    Publication Year: 1962, Page(s):26 - 30
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1912 KB)

    An electro-optical device is described which provides a continuously-variable dc electrical signal in response to a shaft rotation. The elimination of a mechanical contact provides low torque, long life, and high-speed operation. Shaping of the thin film resistance track associated with this device produces an interesting function generator. Data is presented for successful operation of the labora... View full abstract»

    The relative advantages of analog and digital techniques in simulating complex, nonlinear systems in real-time are discussed. A hybrid configuration is suggested consisting of a basic digital computer and peripheral, high-speed analog elements used on a time-shared basis under the control of the digital program. Programs for function generation and for the solution of the aircraft roll equation ar... View full abstract»

  • Parametric Techniques for Eliminating Division and Treating Singularities in Computer Solutions of Ordinary Differential Equations

    Publication Year: 1962, Page(s):42 - 45
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (527 KB)

    By using the analog-computer independent variable time, as a parameter, a differential equation can be transformed into a set of first-order equations containing no divisions. This makes it possible, by means of other mathematical transformations to prevent unbounded functions from occurring during a computation and sometimes to continue solutions through singularities. The discussion includes a d... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1481 KB)

    A new kind of digital computer employing analog computing techniques is introduced. Planned as the central calculator in a ``faster-than-real-time'' computing system for a space range, the computer employs many, high-speed, digital circuits in parallel to calculate the solutions to sets of nonlinear differential equations. Parallel computing equipment employing simple numerical algorithms are show... View full abstract»

    An analog-computer flow chart is developed for use in setting up a simulation of the steam-generation process in a heat exchanger. It is assumed in the paper that the rate of heat flow from the primary side of the heat exchanger to the secondary side is already known. The technique described considers only the process in the secondary side of the heat exchanger. Factors such as variations in press... View full abstract»

    A method is described for the analog computation of the solution of linear two-point boundary value problems, i.e., the problem of a linear ordinary differential equation with linear two-point boundary conditions. The nonhomogeneous problem, in particular, is considered; the differential equal for y on the real interval 0¿x¿1 is taken to be nonhomogeneous. The method for its solution is based up...

    This paper describes a procedure for correct calculation of the resistance of the potentiometer function generator, including the load resistance of the generator. The possibility of generating the function by taking inequidistant values of the independent variable is also described as is the possibility of generating some special functions.

    Some sequential machinies contain input-independent parts and can therefore be input-inependent machine (an autonomous clock) and an input-dependent machine. Necessary and sufficient conditions on the flow table are obtained for the existence of autonomous clocks in sequential machines, and the properties of these machines and their clocks are studied.
