Similar to the work [32], we assume that an uninterested node changes to interested and that satisfied nodes discard the information according to

exponential distribution with parameter [rho] and [mu], respectively.

This distribution comprises the Rayleigh and the

exponential distributions as superior cases.

Using expansions (11) and (12), it is possible to obtain mathematical quantities of the special model such as ordinary and central moments, moment generating and characteristic functions, general coefficient, Renyi entropy and some others from quantities exponentiated of

exponential distribution.

1995) fitted an

exponential distribution on the prime gaps and used the result to prove that:

In Section 2, some properties of the lifetime of product with the

exponential distribution are introduced.

Session duration process is approximated by an

exponential distribution with the average value of 30 minutes [30].

The

exponential distribution is commonly used to model lifetimes.

n, follow standard

exponential distribution Exp(1).

from a uniform distribution on [0,1] or an

exponential distribution with mean 1, and then to set

2] representing the

exponential distribution parameter can be obtained as an inverse value of the mean of all burst/gap lengths smaller than or equal to the threshold in the first case and longer than the threshold in the second case (the inverse value is in fact the effect of

exponential distribution contribution to the Poisson process, the mean value of an

exponential distribution is inverse to its only parameter, so must be the mean calculated from the example set).

Yang and Gaudoin [5] investigate the effect of misspecification of the shape parameter of Weibull distribution by transforming the data to the case of

exponential distribution.

For the SC case in which it was assumed for illustrative purposes that all Justices were replaced every year, it may be that the

exponential distribution does not apply.
