Finding the precise values of optimal parameters is a very difficult task.
The precise values of aquifer properties are usually uncertain because they are only sparsely sampled, yet are highly heterogeneous.
In practice, however, due to the limited resource, it is often hard to estimate the precise values of the parameters in the MDCFP model.
In real life, it may be difficult to obtain sufficient data to estimate the precise values of the performance levels of modern engineering systems.
Yet in most of the existing researches, there is no model parameter uncertainty in the modeling process and the optimal settings can be implemented at the precise values.
Again, although the precise values differ from those given in the illustration of Fechner's Law, notice that big changes in I yield small changes in S, just as predicted by Fechner.
It extends from 1.52 to 1.95 Saturn radii and has optical depths between 0.4 and 2.5, the precise values dependent on both distance from Saturn and wavelength of light.
The modelled muscle operated over only one limb at intermediate values of these two ratios (LTR LF·OPT= 5; LF·OPT:r="3), whether this was the ascending or descending limb was determined by the precise values of the other parameters.
Although various models have been developed in the literature, because of the shortage of manufacture information about the precise values of the parameters required for the modeling, the parameter extraction is an essential task.
The ion bombarding energy to the floating probe, given by the time-averaged potential drop across the sheath, fell sharply from values up to 65 eV in the 'on' time to less than 2 eV in the 'off' time, the precise values varying slowly with power and duty.
