According to plastic waste generation data in 2010, the waste generation in the United States and Japan reached 0.34 and 0.17 kg/person/day, respectively, whereas the waste generation in India, Malaysia, and Indonesia were 0.01, 0.2, and 0.06 kg/person/day respectively [1].

In addition, there are also some researches using the fatigue life of steel after reduction to estimate the fatigue life of reinforced concrete members.
By using a large number of test data, the fatigue equations of different factors were obtained by linear fitting.
Test data proved that the fatigue life and probability distribution of equivalent fatigue life with stress ratio parameters were subject to two-parameter Weibull distribution.
Estimation of fatigue stiffness method is mainly function method to establish the reduction coefficient of bending stiffness.
(3) Reinforced concrete beam fatigue performance of research ideas is mainly based on the cumulative damage theory and test data were obtained by the regression of the cumulative damage model.

The Practical Significance, Suggestions and Implementation Results, Experimental Data Acrylic polymer additive characterized as a hydrophobic plasticizing modifier containing a microfill pigment and mineral supplement will have a positive effect on improving the corrosion resistance of concrete.
However, these tests give a wide space of data, with a coefficient of variation of 13.5% set by GOST 18105-86 for the concrete strength hardening in water [17, 20].
The minimum size of the sample, which reduces the spread of the data should be used in tests for corrosion resistance, is 2.5×2.5×10 cm, in terms of flexural strength.
In the sulfuric acid solution, weight reduction of samples was 60%, the penetration of the acidic environment in the depth of the samples was reduced 5 times, chemical resistance increased by 13%.
The research data demonstrates the effectiveness of concrete modification by polymer additives, which is the primary protection.

Result and Discussion Evaluation of crystal structure in samples conducted using XRD obtained the conformity of XRD data with the peaks that appear in International Centre Diffraction Data (ICDD).
Figure 1(a) showed that all samples have major diffraction peaks observed around 24.13o, 33.11o, 35.61o, 40.83o, 49.41o, 53.99o, 57.49o, 62.38o, 63.96o, 71.798o, and 75.41o, which typically correspond to the ICDD No. 89-0598 reference data diffraction pattern [13].
The crystallite size data in Table 1 is also presented as graphs/curves to facilitate discussion.
The absorption shift shows a reduction in physical defects and lattice disturbances with increasing annealing temperature.
It is accompanied by a reduction in the intensity of the band associated with the hydroxyl group (O-H) and water molecules [23].

The parts are sliced into layers of 150 microns thickness and the data transferred to a laser sintering device.
This platform holds the electric engine to drive the prototype and the sensors to collect data during operation.
Measurement data are generated by one path sensor and five acceleration sensors.
Due to reduction of simulation time, the press frame, the platform and the drivetrain are not considered.
To match calculated and measured data it is necessary to work further on the computed results since the simulation neglects the platform and the spiral springs it sits on (see section ‘simulation’).

The presented data points and contours were generated from the series of the measurements: d& vs.
The deposition rate in nm/hour; contours every 50 nm/hour It clearly results from the presented data that heating of the substrate causes reduction of the deposition rate.
Simultaneously, as it results from the data for the series B, the layer-growth rate achieved under the pressure of 100 Pa (but keeping PRF = 60 W and Ts = 80 oC) accounts for nearly 250 nm/hour.
Thus, reduction of the negative temperature effect through the application of risen power not only ensures higher growing rate but also gives favourable conditions to increase nitrogen content in the layer.
The data reported in this work concern a role of the temperature, gas pressure and RF plasma power.

The data on the grinding kinetics of Al2O3 particles were taken.
Experimental data on the grinding of particles of aluminum oxide are presented in Table 1.
Experimental data on the grinding of aluminum oxide Experiment No.
The following relationships are derived: (7) (8) where η1 and η2 – the rate of reduction of pore size at the 1st and 2nd stage of sintering; k1 and k2 – are phenomenological coefficients taking into account the dependence of the pore reduction rate on the amount of CNTs СCNT (parameters a1 and a2), the current pore size l and the current temperature in the furnace chamber T; m1 and m2 are constants characterizing the degree of deviation of the system from equilibrium for the 1st and 2nd stages of sintering, respectively.
From the comparison of the calculated and experimental data on the average size and moments of the density function of the particle size distribution, the kinetic parameter L was determined by equation (3) as L = 7.2·10-3.

These require less energy than conventional reduction technologies while providing pure titanium and titanium alloy powders that are suitable for powder metallurgy consolidation.
The process simulation requires the material property data, which is available in the open literature.
However, the following data need to be measured for the Armstrong powder: Young's modulus, bulk modulus, failure line for the plasticity model, and compaction plasticity model parameters.
The testing of the data acquisition system (for the measurement of the axial displacement, axial stress, and radial strain) for uniaxial compression of cylindrical samples under increased loading is currently in progress.
The process simulation requires the material property data which are currently being measured for the new Armstrong powder.

Belden company, whereas in other cases the 9841 shielding twisted-pair cable (24AWG) by Belden company, which can guarantee the stability of the data.
The In CAN bus network, the maximum line length is essentially determined by the following physical conditions: ① the loop delay of connected bus nodes (CAN controller, isolator, transceivers, etc.) and the delay of bus line transmission; ② bit timing error caused by oscillator tolerance of different nodes; ③ signal amplitude reduction caused by the bus cable series impedance and input impedance of the bus nodes. 
In condition 1 and 2, bit timing determines the maximum bus length; in condition 3, signal reduction determines the maximum bus length. 
When the sending node sends data, waiting to receive from the response node, but the transmission delay increases to the amount of the two-bit response field of CAN, the CAN-bus can not receive a response signal, which leads to communication failure. ②The increase in bus length also results in the increase of junction capacitance between the differential lines CAN_H and CAN_L, resulting in slowing down the rising edge of waveform difference signal, so that the actual bit time becomes smaller; when the bit rate changes beyond the tolerance range, the receiver can not normally receive the data
In such condition, without terminal resistances, the anti-interference and data communication reliability can reduce greatly; sometimes it can even bring about control failure.
