Table 1 Mean value of the electric resistance for the samples Al Initial Sample Al Processed Sample Al Longitudinal section; Оhm/см Cross section Оhm/см Longitudinal section Оhm/см Cross section Ом/см 4,8 4,6 5,33 3,38 On the basis of the obtained data it follows, that the processing of the aluminum samples with the high velocity flow of particles results in anisotropy of the electric resistance: to its increase in the longitudinal direction by 11 % and in reduction - in the cross direction by 14 %.
According to the data of the microRoentgen-spectral analysis, the particles have the chemical composition, close to the composition of the protective body of the microcircuit.

This deformation is responsible for a reduction of the number of possible macromolecular conformations and an increase in the relaxation time of “unfrozen” segmental mobility.
The aim of this work consists in calculation of Tg for amorphous domains proceeding solely from the chemical structure and the degree of crystallinity, with no resort to experimental data.
When the experimental data on the glass transition temperature Tg and melting point Tm are not available, these quantities can be calculated based on chemical structure of any polymer by the following formula [4,5]: (14) where ai are atomic constants, which characterize the energy of weak dispersion interaction in terms of average atomic contributions; bj are constants which describe the energy of strong specific intermolecular interactions (dipole-dipole, hydrogen bonding, etc).
The proposed calculation scheme does not require the knowledge of any experimental data except for the chemical structure of the polymer.

Reduction of terms of manufacturing occurs at the expense of association of a complex of standard processes in uniform technological installation.
Comparing experimental data and obtained by the formula 1, we conclude that the radiation power, the speed of movement of the laser beam and the scanning step are the main parameters affecting the surface roughness of the surface of the sintered layer, but the temperature of heating the powder material must necessarily be included in the model of governance.
Similarly, the mathematical model for calculating the thickness of the sintered layer: (2) Analysis of experimental data shows a decrease in the thickness of the sintered layer from 1000 to 600 mm (fig. 7) when the power range from 30 to 15 watts, so the power-intensive effect on the thickness of the layer.
After processing of a large number of experimental data almost clear boundary of change of quality of a surface of the baked powder material is observed (fig. 8).

Child human finite element model was derived and compered with response data of dummy crash test in 2008 [2].

As a next phase work, a real size of baby car seat will be manufactured and tested to observe the effectiveness of the significant reduction injuries of children from collision accidents.

The reduction in the production batch means the increase of production costs to a certain extent.
It is needed to modify the Access database that stores the data of the Toolbox.
Use the following statement to update the existing data.
Dim cmd2 As New OleDb.OleDbCommand("UPDATE [" & d3 & "] set [" & d6 & "] = '" & d7 _ & "' where [" & d4 & "] = '" & d5 & "'") If some new data need be added to the database, add a data row using the following statement to the Access first of all.
Dim cmd1 As New OleDb.OleDbCommand("insert into [" & d3 & "] ([" & [d6] & "]) values ('" _ & d7 & "')") For other data in the new data row, use the data updating statement.Use the following statement to delete data.

Load versus crack mouth opening displacement diagrams were recorded and (after data filtering and appropriate modifications) subsequently evaluated using the Double-K fracture model.
The measured data were then filtered and appropriately modified at the Faculty of Civil Engineering, Brno University of Technology (BUT), and subsequently evaluated in detail using the Double-K fracture model.
GTDiPS software [1] was used to conduct data filtering and make appropriate modifications to the diagrams (elimination of data point duplication and reduction of the number of measured points).
In addition to the aforementioned specimen dimensions and notch depth, other input data for the Double-K fracture model was taken from the above-mentioned edited Pv–CMOD diagrams.

The fitting of data of rapid ascending branch of every pullout force-displacement curve is carried out, it can be got as follows: (8) In which, the maximum pullout force Fmax should be expressed by xFmax when used as dependent variable, the later part is same.
The fitting of data of stable ascending branch of every pullout force-displacement curve is carried out; it can be got as follows: (10) Analogously, substituting Eq.3 into Eq.10, the final formula of stable ascending branch may be described by the following equation: (11) In which, the correlation coefficient is 0.941.

Realization of Hardware System The hardware system is mainly composed of three parts: the electronic tag, reader and data transmission.
