Figures 4(a) and 4(b) present the standard deviation and mean of solution U, where the random variables [[xi].sub.i] follow a truncated

exponential law in [0,10] with 20% standard deviation ([[alpha].sub.0] = [[alpha].sub.1] = [[alpha].sub.2] = 20%).

Exponential law as a more compatible model to describe orbits of planetary systems.

Based on the

exponential law of [mathematical expression not reproducible] and Wiener-Hopf factorisation, the Laplace transform of f(t, x) can be expressed as

In addition it's a general law that includes the

exponential law with a single parameter [lambda].

It is inevitable to generate the apparent modeling errors by using GM(1, 1) model, so the grey NGM(1, 1, k) model appropriate for the approximate nonhomogeneous

exponential law with stochastic fluctuation was put forward [17].

Mindu and Mason [4] showed that the magma equation also admits Lie point symmetries other than translations in time and space if the permeability is in the form of an

exponential law:

The results in table(1) which pertains to b=1 (belongs to

exponential law and represents constant failure rate [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] (t)) agrees with the results already discussed as a particular case of the modal with

exponential law.

the data transmission is considered to the

exponential law [[mu].sub.0], [[mu].sub.1], [[mu].sub.2] parameters are the parameters of an

exponential lawsAssuming that the BAZ model and the

exponential law of reliability are applicable, the PoF can be defined as

In the case when [lambda](t) = const, the reliability can be expressed by

exponential law:

9 showing similarities existing between the processes described above and the

exponential law.

Specific topics include the methodological principles of chemical kinetics, the method of routes and kinetic models, problems of stationary kinetics of polymerization up to the high conversion rate, non-stationary (post-polymerization) kinetics and kinetic problems, stationary kinetics of three-dimensional polymerization up to the high conversion rate, the kinetic model and the stretched

exponential law, and the statistics of self-avoiding random walks and the stretched

exponential law.
