The data show that the alpha-alumina obtained by burning the pseudoboehmite was highly pure.
The pseudoboehmite x-ray diffraction showed the characteristic data observed in the literature [11,12].
Fig. 3 shows the x-ray diffraction data for the pseudoboehmite calcined at 1200o C.
The data of Fig. 3 is very similar of the alpha-alumina ICDD data and the data of literature [13].
The isotherm adsorption data shows the presence of macropores and mesopores.

Despite the following limitations, difficulties in identifying entry parameters, lack of robustness and reliability in quantitative results and so on, FEM simulation can still be considered as a promising approach to the study of the cutting process, allowing the reduction of the experimental cost.
It can be seen from Fig 3 that water vapor cooling, causes a considerable temperature reduction of tool rake face in cutting process, demonstrates the effectiveness of water vapor cooling.
The simulation results show the same temperature trends with the experimental data [5].
The errors between simulation results and experimental data were from 3% to 12%.
The present simulation results showed a good agreement with the experimental data from other researchers.

This phtenomenon results in the reduction of a pump’s life and efficiency, vibration in framework, and exra noises [1,4,5].
The images showed the reduction of ferrite ratio through depth to surface.
According to the recorded data from table 1, the feed water quality did not have a significant difference from the manufacturer‘s prescribed analysis, except the Electro Conductivity and amount of Calcium and Silicon which were higher than the prescribed analysis.
The data, given in table 2, disclosed the lower corrosion rate for feed water, so resistance to corrosion for this alloy in feed water is in "well" category [8].

For the same data, generated by the grid is unique, ie, not the data or attributes of the order of one of the advantages of this concept lattice.
Association rule mining algorithm Association rules in data can be divided one-dimensional and multidimensional.
One-dimensional association rules, we only involve one-dimensional data, such as the user to purchase items; multidimensional association rules, data to be processed will involve more than one dimension.
The data mining algorithms based on improved-Godin and Apriori are following
The concept lattice model used as a data organization and formalization of data analysis tools; both theoretical research and practical applications are of great significance, it has a broad and successful application in many fields.

The mechanical strength briquettes data for low and high stresses of the mixtures briquetting are obtained.
Some data on the efficiency of the liquid glass using are contained in [4 - 10].
In the conditions of industrial production, the reduction of the liquid glass amount in the briquetted mixture is economically justified, which is due to both technological and economic reasons.
For the construction of graphs, the optimal content data of liquid glass in the raw mixes is selected: 3% for iron ore concentrates; and 2% for ferrosilicomanganese.
The automated line briquetting scheme of CJSC Spidermash Conclusion Analysis of the tests results showed the possibility of a significant reduction in binder consumption during the raw mixtures pressing with high compression stresses.

This is attributed to the fact that, Li being very small in size, interacts easily with dislocations by the overall reduction in the axial c/a ratio.
They are consistent with literature data [10-13].
Our data for as-rolled condition compare favorably with these results in terms of strength.
As shown in Fig. 3, the data fit a straight line yielding k = 1.7 mm2/min.
While the data for Mg-4Li do not support a parabolic grain growth law, it is obvious from this comparison that the addition of calcium has a very significant inhibiting effect on grain growth.

During field studies the various available forms of input data were collected.
Energy usage data is considered to be a pre-requisite for the development of SEU-statements of organisations.
If construction data is not available this data is often not easy to find.
The following section specifies data which is for the development of action plans.
Weather Data: This is required to analyse and normalise energy consumption data, e.g. by using degree days [18].
