It should be noted that the number of data points at 40 bars operating pressure is very limited, especially at liquid load of 10% by mass.
Thus, this limits the amount of data collected at the lower range of liquid load and gas velocity at operating pressure of 40 bars.
Figure 1 - 3 shows that the difference between the maximum and minimum value of all data range is very marginal with standard deviation ranging from a minimum value of 0.21 up to a maximum value of 1.35 as shown in Table 1.
Although the separation performance at lower liquid load is comparable to the separation performance at the higher pressure, there is a significant reduction in separation performance at higher liquid load, even at higher gas velocity as shown in Figure 3.
Considering the very small variance for the experimental data at 50 and 60 bars as given in Table 1, it can be concluded that the separation performance of the horizontal, inline swirl tube separator is fairly consistent.

The optical data were determined with PERKIN ELMER UV/VIS/NIR LAMBDA 900 spectrophotometer.
In the lights of optical data no substantial difference between the two sides were observed.
Therefore, optical data were given without considering air or tin side of coated glasses.
The transmission data obtained at 550 nm after these tests are given in Table 3.
On the other hand, the mechanical and chemical properties of coated glasses with Solution A and C were satisfactory but their transmission data were not as good as coated glasses with Solution B.

Experimental data is mostly analyzed for the induction time and pressure drop.
The results of two groups show that the induction time and pressure drop does not significantly reduction.
b a Fig. 1 Initial pressure 6.4 MPa pressure-time curve (a:without activated carbon, b:with active carbon) Table 2 The specific data analysis of activated carbon hydrogen storage reaction under 6.4 MPa Without activated carbon With activate carbon Percentage increase Pressure drop 0.028[MPa] 0.030[MPa] 7.14% Induction time 300[min] 400[min] -33.33% Density 0.0026wt% 0.0041wt% 57.69% The influence at pressure of 7.4MPa.
Therefore, the data demonstrates that the higher reaction pressure can improve the density of hydrogen hydrate.

Creep model is based on the experimental data with small size specimens.
But the data indicate the hydration heat problem is getting serious with the increasing bridge span.
This paper discussed the accuracy of the hydration heat formulae with the measurement data from the construction site and carried on the research of the hydration heat effect on creep base on the discussion results.
With the statistics and regression methods and the data from the construction sites, literature 5 and literature 6 proposed empirical formulas for calculating the hydration heat of the center and the surface of the concrete plate.
Validation of the method mentioned above has been taken based on the data from Xiangjiang bridge in Baishui, Qiyang.

Monitoring user video receiver should receive video data streams for processing data errors and correction.
This rate control algorithm uses additive increase and immediate reduction methods.
The statistic and computed results of data packet loss rate are shown in Table 1.
To transmit a real-time MPEG-4 data stream and two FTP data streams based on TCP simultaneously between the transmitting terminal and the receiving terminal of the video, transmitting the MPEG-4 data stream 8s after the transmission of FTP, and designing the function of opening the adaptive control system.
On the other hand, because data FTP is operated based on TCP, when the parallel streams of the data FTP are increasing, it will adjust itself according to congestion control mechanisms, which reflects that the rate of FTP data per channel will decline.

We have to discover the data types to be recorded and determine the requirements for data recording, as well as elaborate possible methods and procedures for evaluation and applications of the data.
These systems are able to collect data from their environment, and after analysing these data they are able to modify their positions.
- Big Data concept [4]: The amount of data in the world approximately doubles every two years [6], which results in huge amounts of data in the different areas of life (astronomy, logistics, trade, the stock exchange, etc.).
We cannot speak of cyber-physical systems and big data without IoT.
One consequence of collecting so-far unknown data is the need for implementing new data collecting equipment and online data transfer equipment.

The experimental data obtained by both methods coincide within the experimental error and indicate the extremum availability on ST isotherms.
The obtained outcomes and their comparison with experimental data have shown that the considered models for predicting surface properties based on data due to similar properties of lateral binary systems adequately reflect the experimental dependences.
Reliable experimental data on ST and molar volumes of both binary and multicomponent melts are essential to solve this issue successfully.
ST isotherms of melts of the In-Pb binary system: 1 – from [9], 2 – from [8], 3 – data from [16].
We have demonstrated that the surface tension of multicomponent systems is predicted on the basis of the ST data of lateral binary systems.
