On the Design and Generation of the Double Exponential Function

چکیده
For the double exponential function f(t) =K(e~ e~), which is used for impulse testing of electrical components and systems, we derive an approximate relation between the ratio ym = Tm / T m a x , where Xmax and Tm are, respectively, the times to reach the peak value F m a x and the value .Fmax / m on the tail of the pulse, and the ratio x = 6/ a. This relation is useful for finding x for a prescribed ;/,„. where m is usually equal to 2. Our formula is much simpler than that given by Googe, Ewing and Hess [1], but gives results of comparable accuracy. We also present a number of RC two-ports, alternative to those of [1], for generating the test function / ( t ) from an impulse function S(t), as well as from the step function u(i).

متن کاملEffects of Probability Function on the Performance of Stochastic Programming
Stochastic programming is a valuable optimization tool where used when some or all of the design parameters of an optimization problem are defined by stochastic variables rather than by deterministic quantities. Depending on the nature of equations involved in the problem, a stochastic optimization problem is called a stochastic linear or nonlinear programming problem. In this paper,a stochasti...
متن کاملDesign of Economic Optimal Double Sampling Design with Zero Acceptance Numbers
In zero acceptance number sampling plans, the sample items of an incoming lot are inspected one by one. The proposed method in this research follows these rules: if the number of nonconforming items in the first sample is equal to zero, the lot is accepted but if the number of nonconforming items is equal to one, then second sample is taken and the policy of zero acceptance number would be ap...
