Based on the obtained experimental data the software automatically calculated the value of specific surface area of the sample by BET method.
Mie Scattering Theory is used to determine the quantity of particles of that diameter which will produce the measured reduction in beam intensity.
Experimental data of particle size distribution in ethanol suspensions correspond with the microscopy data
Table 2 shows the data of specific surface of SPE products in different conditions of dispersion in compartment with the value of specific surface of WC-6Co chip scrap after mechanical grinding sifted to the fractions less than 63 μm.

The higher the pressure ratio of the compressor, the greater the reduction in the overall thermal efficiency of the turbine.
In order to estimate the parameters in the PH model it is necessary to have the historical data collected under the given operating conditions.
The data consist of aging times, feature sample paths and indicators of events (failure(on-line washing) v.s. censored).
Then the likelihood function of the collected data is given by: where is the number of offline washing , is the number of surviving and offline washing, the offline washing time of the ith unit.
The historical data including 160 on-line washing records from 2000 to 2004 are used to establish a PH model to estimate the RUL of compressor.

Background of Case Study In the elaboration and foundation of case study are necessary defining the particularities regarding the entrance data about the energy request and consumer’s placement, the characteristics of energetic conversion systems, the optimization criteria for system’s configuration, control strategies regarding function of energy generation system and particular financial data to the studied hypothesis.
For the building analyzed was calculated the total energy load at 6759 kWh/year [2], situated in Cluj-Napoca, placement with an availability of primary sources of solar and wind energy according to the official data and professional literature [3,4].
As a general input data set to be allowed to use in parallel a maximum of 30 for PV and a maximum of 2 for TE and was also imposed a maximum of 1% as restriction regarding the maximum permissible load on the percentage annual uncovered.
Fig. 3 Percentage costs of energetic system The generation, stocking and conversion technology of hydrogen is in a continuous development, and as they will be validated the researches visualize a reduction of costs, and these types of equipments and technologies will be competitive in the close future to other technologies from the production and energy stocking domain.

Aballe et al. proposed the discrete wavelet transform (DWT) as a suitable method for subsequent data analysis, which decomposes the data set into several time scales, dn and sn, called crystals by overlying the noise signal with a selected wavelet function.
The electrochemical current noise data were analyzed by the discrete wavelet transform using the MatLab R2017 software and the integrated Wavelet Analyzer tool.
For ensuring a similarity between the curve shape of notified corrosion events in the noise signal and the used wavelet function for the DWT, the symlet function 2 at level 8 was chosen for the data analysis of both signals.
For data interpretation, the coefficients were related to the original noise signal and the observed damage evolution after the tests.

The second half of the task lies in data analysis of finite element analysis, changes to the original geometric model of the work object.
Point is that each CAD system preserves the geometric model in a format that is accessible only to itself; this is connected with the task of finding a universal and publicly available format of data exchange between different CAD systems [1-3].
These steps are aimed at reducing the total amount of data.
The first batch will be processed according to the CNC data developed on the basis of the initial geometric model, and the second batch - according to the modified geometric model.

The addition of only 0.5 wt% CNTs to the CNT/PU composite caused about 50% reduction of the wear.
For the composite with 2 wt% CNTs, the scatter of the wear data is more pronounced than for the other samples.

Our data indicate that the TiO2 nanowires are synthesized uniformly and also the Ag nanoparticles are coating well on these nanowires.
To coating these nanowires with Ag nanoparticles, we use a reduction method [11] to get Ag nanoparticles from AgNO3 solution.

Table1 Experimental data of straight and parallel degree Figure 6 Percentage of straight and parallel From Table 1 and Figure 6, we can see that the cotton percentages of straight and parallel are less than those of fibers, so it is clear that the flats-delivered device is better for fiber adaptation.
The percentages of straight and parallel increased with the reduction of lengths.
