    In this paper we consider the problem of the voltage oscillations in a transmission line when a diode represented as a nonlinear capacitance is placed in shunt in that line. In particular we consider the response of this line to periodic driving voltages and study the periodic responses. This physical situation is shown to lead to the mathematical model of the wave equation in the voltage in a dom... View full abstract»

    An analysis is given on the mechanisms of operation for a current-multiplying hook collector of cylindrical geometry. Mathematical equations are presented which establish the minority carrier transport efficiency within a cylindrical hook collector region; both surface and bulk recombination are assumed to be present. Also included in this analysis is the influence, upon current multiplication, of... View full abstract»

    This paper surveys some numerical methods applicable in obtaining the distribution of performance parameters associated with the transient behavior of switching circuits. The methods considered are: (1) Monte Carlo, in which sample circuits are simulated on the IBM 704 and their performance computed and tabulated. (2) Parameter sensitivity methods, including propagation of error, in which the firs... View full abstract»

  • Analysis of a Constant-Input-Flow Hydraulic System

    Publication Year: 1961, Page(s):44 - 55

    An analysis of the system is discussed and its application to a paper form feeder carriage in a printer is described. A nonlinear differential equation is derived based on stated assumptions and lumped oil parameters. The equation is linearized and solutions for motor velocity and peak pressure, both versus time, are determined. The analytical results show the effect of system parameters on system...
