The C/H ratio in the carbonized layer is confirmed by the data of IR spectroscopy both at the preparation stage and after exposure to characteristic temperatures.
Among other requirements for the polymer composites characteristics is the reduction of the combustibility of polymers used in all industries and construction.
As can be seen from the presented data, the ratio of hydrogen to carbon in the polymers is quite high.
Characteristics of the polyepoxy destruction process Polyepoxy The area of the maximum destruction speed [°С] Amount of carbon residue [%] 4, 4'-diglycidyl ether - 1, 1'- dinaphthol 270-590 22 Bromine-containing epoxy system 280-680 19 2, 2'-diglycidyl ether - 1, 1'- dinaphthol 320-700 14 4, 4 '-diglycidyl ether - 1, 1'- dinaphtholmethyl 330-720 12 The analysis of table data shows based binder 4, 4'-diglycidyl ether - 1, 1'- dinaphthol has a lower content of volatile components in the destruction, as well as a large percentage of the output of carbon residue, making it the most perspective for use in fiberglass systems among proposed binders.
In addition, a comparative analysis of the experimental data showed that the material based on 4, 4'-diglycidyl ether - 1, 1'- dinaphthol was more thermostable from the obtained polymers in inert conditions [10].

Also presented are numerical simulation data on thermal fields for the same conditions, showing a good agreement with the measurements.
Experimental data together with theoretical predictions allow a preliminary analysis of the technological process and its individual stages.
Here we present experimental measurements and numerical simulation data for the surface temperature of VT1-0 titanium during intense electron beam irradiation.
The specimen was fixed on a table-manipulator with thin strips of stainless steel foil (for heat loss reduction during measurements) and was placed in the vacuum chamber of the SOLO setup where it was moved and positioned with a programmed two-axis manipulator.
The cross-sectional electron beam density distribution at the target surface in different irradiation modes was measured using a calorimeter composed of nine Cu sensors (Faraday cups) arranged in line at 8 mm from each other (center distance), covered with a flat diaphragm having holes of diameter 3 mm, and connected to thermistors and automatic reading system to take data from them directly after an electron beam pulse.

The results realized from the analysis of the three ponds were compared with data published by other researchers and also the standards specified by the Malaysia Environmental Quality (MEQ) Act 1974.
It is also found that the aeration process in aerated pond could enhance the reduction of pollutants in the leachate.
The values of the parameters gathered were compared with the data published by previous researchers and the acceptable discharge limit set in the Environmental Quality Act of Malaysia 1974 (MDC, 2010).
It is observed that aeration leads to a reduction in the SS in it.
(Kulikowska et. al., 2008) reported that, as landfill becomes mature and stabilized, their pH values increases, thereby resulting in a reduction in metal solubility which in turn affects the oxidation-reduction processes and acid dissociation.

Early detection by a highly reliable classification of skin lesion causes a great reduction in the mortality rate.
The second is fine-tuning which is based on replacing the last fully connected layer to the new classes and retrain the whole CNN using data based on the new modification.
The segmented lesions are classified into their corresponding classes using CNN. 70% of the total data set is for training the network and the rest data is for test purposes.

The method could reduce the data quantity of valley model.
To reduce the multi-resolution terrain model data.
The specific methods of operation as follows: gradually removing those points that meet certain criteria of vertex data reduce from the big scene including all the triangle mesh terrain data until data reduced to the details of the required accuracy so far achieved.
The advantage of this approach is able to extract more continuous level of detail triangle to support data compression and geometric reconstruction of data for network transmission of data in the drawing of the model client.
The real-time data transmission is to provide a new idea for WebGIS.

The value of ϕj is estimated by fitting the AR model to the time history data.
The training data were composed of half of signal 1 and 2.
In order to compensate for the nonstationarity of the AR parameter sequence, the training data and testing data were taken alternately from the relevant feature sets.
Better diagnosis was obtained by employing multiple data sets than just by using each test data set separately.
