Various methods of interpolation (approximation, smoothing, and filtering types) which take measurement noise into account
(piecewise polynomial approximation, smoothing splines, kriging, filters, etc.) are analyzed. It is found that regularization
methods are used in all of them. The advantages and disadvantages of these methods are pointed out and prospects for the use
of program packages by nonspecialists in mathematics and information technology are examined. Recommendations regarding the
proper choice of estimation techniques, quality criteria, and parameters for monitoring them are made in the case where geofields
are to be approximated and modelled. 相似文献

Various methods for reconstructing the parameters of geofields taking measurement noise into account are analyzed. Program
packages for nonspecialists in the theory of programming are discussed. Recommendations are given regarding the correct choice
of method and control parameters for approximating and modelling geofields. The advantages and disadvantages of these methods
in different stages of the recovery of the parameters of geofields are examined. It is proposed that fuzzy neural networks
be utilized in the early stage when the data are uncertain and limited. 相似文献

In this work, we study the effect of the structure and charge state on the strength properties of nanocomposites prepared
on the basis of polypropylene (PP) and D
k2 nanoclays. It is shown that the addition of the D
k2 nanoclay into the PP polymer increases the concentration of the centers of localization of electric charges; that is, interfacial
layers are formed at the polymer-nanoclay interface; they can play the role of a trap for charges; this results in an increase
in the density and stability of the electret charges. A change in the interfacial interactions and the thickness of the boundary
layer can have an effect on the strength properties of the nanocomposite. 相似文献

The crystallization dynamics of Bi2Te3-Bi2Se3 polycrystalline films annealed at 200–230°C has been investigated. The formation of ordered blocks 70—150 nm in size, depending
on the annealing time and temperature, is observed. 相似文献
