However, the elongation under shear manifested a reduction when the number of ARB passes increased.
Slabs were preheated at 350oC for 5 minutes before each pass of the rolling, and it was rolled with a thickness reduction of 50% per cycle[6].
A reduction in individual layer thickness was detected with increasing the number of ARB passes.
The slope of the fitted line between the tensile data and shear data indicated the correlation coefficient (m) and was found to be about 1.1339.

Thus, a 24% decrease in pore size and reduction in their dispersion by almost 30% is noticed.
Then we examined the flexural strength of the samples, which was evaluated by the sample fracture strength determined on a special strain gauge setup with computer data processing .On the basis of the results obtained by calculations we determined the limit of bending stress.
Experimental Results and Discussion On the basis of mathematical processing of the experimental data [22] for samples with electromagnetic processing after the formation without impregnation approximating function was derived: , where F is the external force, resulting in the destruction of the sample, H; Рsp is summed up intensity of the electromagnetic field, W/cm3; τ is influence time, s.
The mentioned above confirms offered by us mechanism, according to which the increase in the uniformity of the structure and reduction in pore size after electrophysical processing increases the number of connections between the agglomerates of structure and increase in the limit bending stresses.
Thus, a 24% decrease in pore size and reduction in their dispersion by almost 30% is noticed.

Test data for compression tend to show that there is no substantial sensitivity to the strain-rate concerning ultimate strength and Young modulus.
Reduction of specimen overheating is achieved by utilizing “cold” LED lights for the illumination.
To obtain reliable experimental data about 5 repetitions for each type of tests have been performed.
Fig. 5 a) Brazilian test setup and typical stress/strain field b) static experimental data For the reduction of local compression peaks small pieces of compliant materials (bearing strips usually made of plywood for concrete specimens) are used to better distribute compression loading and to avoid the propagation of initial cracks.
Fig. 6a summarizes the data results obtained by the dynamic splitting tensile tests.

The data was gained by performing tensile tests with tubular samples (DIN EN ISO 6892-1:2009-12).
To compensate torsional errors that occur because of this simplification, empirical data tables are used.
To reach the aim of this investigation, being the generation of an analytical model for 3D bending using TRPB, primarily, an experimental data basis is needed.
To analyze the experimental data, first, the data was compared with the geometrical description of a helix (see Fig. 3).
The relation of the analytical calculation to the experimental data is also shown in Fig. 6.

It has been established that biomarkers can provide data both on effects of pollutants and toxic metabolites formed during its transformation in natural conditions and cumulative action of pollutants.
Data on concentrations of Chl a and its variability in water is an important criterion for measuring phytoplankton reserves and its production and water contamination indicator [9].
These data suggest that NPs CeO2 inhibiting effects on Pseudokirchneriella subcapitata are mediated by interaction between cells and membrane-damaging NPs.
Studied cellular enzymes covered with NPs, as authors consider, are consistent with the documented data [22, 24] on NPs CeO2 toxicity against algae.
Consequently, the data obtained from this study show bacteria Paramecium c. and fish Danio r. to be more tolerant to NPs CeO2 compared against Сhlorella v.

There are two data collection techniques used, namely direct and indirect methods [9].
SvCoal,ton=SVEnergi, GJ x Total Coal yang dibakar, tonTotal HHV Coal, GJ (6) Step 6: Calculation of greenhouse gas emission reductions with equations [12] Regas emissions =SvCoal, ton x FE, ppm (7) Where FE is an emission factor taken from data released by the Environmental Department of Power Plant of Paiton Unit 8 as in Table 2 below: Table 2.
Then the average value of the data is taken and the results are obtained as in Table 3, from the data calculated enthalpy and flow of each process.
The enthalpy of each data is searched based on temperature and pressure references on the steam table [11].
Then an interpolation method is carried out to find out the value of a variable that is missing in the known data range on the steam table.

A major problem with this type of test is that a set of undamaged test data is required for comparison.
For a method to be useful in detecting damage in an existing bridge, this need for undamaged data must be relaxed.
The data were sampled at 25 kHz after anti-alias filtering.
The following data analysis used the mid-span acceleration data
Using these data, time-frequency relationships where derived for varying levels of damage.

Though there is a lack of experimental data for high Cr steels by X-ray microtomography currently, but (b) has provided reference value for studying creep cavitation behavior in high Cr steels.
The creep data is very limited, and the extrapolation if such data using the conventional empirical methods may not be reliable.
The quantitative data also validated the description of creep damage by numerical methods.
The quantitative data provide a function of describing nucleation, growth and coalescent with creep damage exposed time in dual phase steels, but yet getting in high Cr steel.
Further work should be provided more experimental data of X-ray tomography for high Cr steels need to quantify the experimental data of X-ray tomography for high Cr steels from planning new experiments and develop new creep cavitation model that the fundamental work for the development new creep damage constitutive equations for high Cr steels under high temperature at low stress.

Encoding the movement skill into the model instead of recording the whole skill data leads to the reduction of the storage size.
System Data Flow Fig. 4 presents four main parts of the system.
The first part is called system training where the spatial and temporal data will be gathered by the data-gathering module.
After the data collecting, the gathered data will be sent to the GMM initial parameters' module to obtain the initial parameters.

The reason for the de-NOx SCR activities decrease on two aged samples and the higher anti-aging performance of the sample with ultrasonic treatment could be deduced by XRD and SEM data.
