The data obtained from the experimental analysis is suitable for developing the numerical model for HT distortion.
This mark was used to identify the relative angular position of distortion measurement values, for showing the angular shifts in the distortion data.
Therefore, the distortion data with furnace cooling is treated as that of a heating process just before quenching in a HT process.
This distributed data of distortion are represented by a Weibull plot.
The data shift more on the right side toward higher distortion value in case of 0.4%C-CrMn steel than SUS304.

Literature Review
Anthropometric data are used to ensure that products are produced to fit and suit as many people as possible.
Antropometrics Data Measurement The results from the measurements of anthropometry are listed in Table 1.
These data were measured and analyzed by using Statistical Package of Social Science (SPSS Version 16) for data analysis of the reliability studies.
In general, most of the female‘s anthropometrics data shows the higher value compared to the male‘s anthropometrics data except for hip breadth and weight.
Conclusion In conclusion, the anthropometrics data of the primary school children has been developed.

Based on all of this experimental data, the effects of the characteristics of the ion
exchanged Y zeolites on the catalytic activities in the reduction of NOx have been studied.
The data of the specific surface area of the zeolitic catalysts measured by the BET method is shown in Table 1.
The analytical data of the Si/Al ratio shows a variation from 0.003 to 0.49 which is a little change in its value from its original value.

The pressure reduction as the increase of roughness can be neglected compared to the normal pressure.
Data for the simulation model were obtained from experiment information.
Primary data include pipe geometric characteristics and materials arejust as same as the experiment done by Anton Bergant[5].
Figure 4.Model of the fluid area (Detail View) The Reynolds numbercan be calculated form the data above, and as this model accord with boundary layer theory, the thickness of boundary layeralso be obtained from corresponding formulas.
Flow velocity under different roughness For further study, detail pressure data of 0-0.3s and 0.7-1s are plotted separatelyin Fig.10.

Manipulating this equation and introducing the data for the CO2 emission, the IO-equation for CO2 emission can be established.
It is based on a number of assumptions such as the proportionality assumption, the homogeneity assumption and the conversion of economic data into the physical quantities such as the energy and CO2 intensities.
The process analysis data represents a better estimation of the CO2 emissions on site by detailed process.
Then the low carbon technology implement for systematic emission reduction can be possible.
The CO2 emission analysis is very dependent on the source and availability of the data.

Bending tests in either 4-point or ring-on-ring loading
provided the fracture stress data, which were further analyzed in terms of Weibull statistics [10].
To predict the failure stress in larger components the data are extrapolated from small specimen results.
Since especially the high temperature measurements were based only on a limited number of data, the average MOR of the anodes was calculated assuming that all measurements generate a single m-value due to the same flaw distribution.
Based on normalisation of the data using the MOR values for the oxidised, reduced, RT and HT state, an averaging characteristic Weibull modulus of 13.2 ± 1.2 was obtained.
The reduction in fracture stress can be calculated [15].

Peak reduction problem.
The algorithm is sufficiently scalable and can be trained on historical data as well as online in a dynamic environment.
If trained well and on data with a high variation, DQN can sometimes outperform human performances on complex tasks.
One can try to initialize the weight of the Q-Network by applying a supervised learning phase with historical data gathered from existing optimization algorithms.
The main controller is a PLC, which controls the production machine, communicates with partners and obtains energy data from the drive and the power supply via Profinet.

Therefore, in-depth analysis of decoupling between carbon emissions and economic development, to achieve energy-saving emission reduction in China, while maintaining economic growth has an important guiding significance.
Carbon emissions measurement and data description The literature indicate that the major factor of carbon emissions include economic growth, industrial structure, energy efficient, energy structure and so on.
The data were taken from China statistical yearbook and China energy statistical yearbook.
Therefore, China should vigorously develop and promote energy-saving technology, improve the carbon emission reduction technology, to further improve energy efficiency
And then, china government should play the leading role, encourage enterprises to introduce foreign advanced technology of low carbon, establish reasonable mechanism system, in order to realize the goal of emission reduction early.

These concepts and methods are called SMED, Quick Changeover, Setup Time Reduction, and or Turnaround Time Reduction.
Three important tools that were used in collecting data are stop watch, cam recorder and camera.
All the data were analyzed and the improvement activity was carried out to improve the current machine changeover time.

Good fit is obtained between the predicted values by
the microstructure model and the measured mill data, with an agreement generally within the
interval ±15%.
Material and Experimental Procedure Commercial HSLA steels were used in this investigation and process data were collected from SSAB's hot strip mill.
In order to calculate the microstructural evolution of the material, the required process data is the soaking temperature in the reheating furnace, the reduction and rolling speed in each pass and the temperature.
As input data to the friction-hill model, measured process data, such as measured roll forces and geometry of the strip, were used.
For the 8 mm strip, the model gives an accurate prediction of the flow stress evolution compared to measured data.
