This method takes advantage of innumerable neutron counts and makes inferences about the properties of uranium components observed by the correlation function
between the [sup.252]Cf source and detector.
Earlier in the 1940s, Born and Green  set up a correlation between the viscosity of liquid, the pair correlation function
g(r), and the pair interatomic potential C(r).
The measurement of path loss and shadowing correlation on two TV channels are performed in urban, in which the exponent and autoregressive model for correlation function
are presented .
It is noticed that most subspace system identification methods are based on the input and output data in time domain, and the frequency response methods of some linear time invariant systems are often based on the signal correlation function
In the 4-dimensional space-time, though the geodesic length does not equal the area of the minimal surface, it has been shown that both the geodesic length and area of the minimal surface, which are dual to the two point correlation function
and entanglement entropy respectively, are nonlocal probes and have the same effect as they are used to probe the thermalization behavior and phase transition process [23-40].
The product of the fluctuations of the indicator function [mathematical expression not reproducible] is the correlation function
[mathematical expression not reproducible], which characterizes the relative position of the components in microstructure.

for generic sine-phased binary offset carrier signal tracking," Computers and Electrical Engineering, vol.
Therefore, a necessary and practically sufficient condition for the homogeneity of the correlation function
within the region under consideration is the fulfillment of inequalities
This correlation function
is denoted by r(n) and expressed as 
Calculations showed that under load, which is exponential correlation function
R([tau]) = [De.sup.-[alpha][absolute value of [tau]]] by statistically optimal transfer function of the regulator will be consistent connection aperiodic link and forcing a first-order link [W.sub.reg] (s) = [a.sub.0]s + [a.sub.1]/[b.sub.0]s + [b.sub.1], and for loading of exponentially-cosine correlation function
R([tau]) = [De.sup.-[alpha][absolute value of [tau]]] cos [beta][tau]--serial aperiodic link and forcing a second-order link [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII].
To conclude, we compare the results obtained using the MAC (Modal Assurance Criterion) correlation function
in structural dynamics [7, 8].
