This process may be realized by customer behavior data clustering.
Then, we get the reduction table of the customers’ data analysis and decision.
The data stored in the server cannot meet our requirements for data analysis, therefore, we need to preprocess these data, and namely, the data will be extracted according to our requirements and will be stored in our database used to analyze the data.
This process may be realized by customer behavior data clustering.
Then, we get the reduction table of the customers data analysis and decision.

We find that the capacity of energy conservation and emmision reduction of eastern region is best, the western region is in the middle level, while the central region is not good enough.
Table 1 The meanings of parameters Parameter Explanation the total CO2 emissions of the whole country based on unit GDP energy consumption, (Unit: thousand tons) the total CO2 emissions of province j based on unit GDP energy consumption =44/12, the molar ratio of converting C to CO2 carbon oxidation coefficient of standard coal, we set it as 0.9 the heat transfer coefficient of standard coal, we set it as 29.27 the average carbon content of standard coal, we set it as 24.74 unit GDP energy consumption of standard coal in province j GDP of province (city) j The data of emissions come from the journal China Environment Yearbook, the data of power consumption and conversion coefficient and related data come from China Statistical Yearbook.
Because the data of Tibet is not complicate, we just predict 30 provinces (cities) CO2 emissions.
We used the data of population from China Statistical Yearbook to calculate the per capita CO2 emissions, shown in Figure 2.
In this respect, improving the industrial structure and technical level in high emission intensity areas can promote the emission reduction with a lower cost and more efficient way.

An experimental and numerical investigation into forming force reduction in precision gear forging Nicholas J.
As maximum force, along with workpiece size are the two key specifications for industrial forging presses, a reduction in the load required to fully fill a die translates directly to a reduction in the capital investment cost of a production process.
Experimental true stress-plastic strain data is used up to a plastic strain of ε = 0.401, and thereafter the properties are represented using the power-law equation, σ=σy+Kεpn, where: σy=7MPa, K = 96.63 MPa, and n=0.3955.
