According to the basic theory in quotient space granularity world, we can analyze data sample from different levels of granularity and preprocess these sample data.
This is mainly a partition of the data set about the equivalence relation.
We describe the sample after the dimension reduction through one dimensional data and we sorted for one dimensional data values in descending.
Step 3 we describe the sample data after the dimension reduction and normalization by one-dimensional z value, , .
We get the data sheet after summary of sample data and the normalized processing, as shown in table 1.

The soil material is extremely draining and clay-free, with a good resistance to the compaction and volume reduction.
Data Collection.
Relationship between soil depth and volum reduction (Vin/Vout) and flow peak reduction (Qin/Qout).
Particularly, the results obtained from the relationship between soil depth and volume reduction (Vin/Vout) and peak flow reduction (Qin/Qout) could be very useful for designing and verification purposes.
For all the tests carried out a clear dependence between the rain intensity and the reduction in volume and flow rate hasn't been observed.

Generally speaking, such studies are from the consumer point of view, rather than producers, and most of using transportation and consumption sector data.
This data is only half of the rebound effect of energy resource studied for all periods.
Because of limited data collection and acquisition, there are fewer researches on the direct rebound effect in China.
Using 28 provincial panel data from 1985 to 2005 in China, Liu Yuan Yuan et al.[10]find that the economic-wide rebound effect is 53.68 %.
Because of using the different data and estimate methods, there are some differences in empirical test results.

Just as rolling force and reduction calculation, oil flow is also calculated simultaneously according to the primary data.
Architecture of the RGL control system Lubrication hierarchy data creation Oil flow references come from data table perfected by commissioning.
All reference data is simultaneously downloaded to the FM PLC.
The oil flow data can be displayed by the man-machine dialogue.
Hierarchy data can also be inquiryed and modified according to query conditions.

Today, also in SMEs, IT are used to solve the problem of data exchange.
Therefore, functions are duplicated, the data is repeatedly entered manually, and it is not possible to receive the interconnected data flow.
Very often this data is defined and entered manually.
Today, the access to data managed by both the ERP and CAD/PDM is required as well.
Thus it is necessary to implement the mechanism of synchronization of the exported data.

The authors studied the correlation of mechanical properties and the content of alloying elements, impurities, bar diameter, and post-annealing (using various industrial modes) structural parameters, on the basis of the analysis of production data, and established regression dependencies for estimating average values of mechanical properties of bars on aluminum and molybdenum strength equivalents of alloying elements and impurities.
For instance, in 1970s-2000s, the level of aluminum equivalent interstitial impurities decreased from to , which resulted in the reduction of the β-transus temperature by 20-30 0С and of the strength limit of industrial titanium alloys by 50-100 MPa [7, 8].
We also discovered that increase in the diameter from 15 mm to 150 mm leads to a considerable reduction of all the studied properties (correlations coefficients R = -0.65 ÷ -0.68).

If the reduction in weld strength due to the existence of pore is less than that caused by rework.then it is prudent not to go for rework and accept the porosity as is if the strength reduction is acceptable.
This papers attempts to give the necessary theoretical backup along with experimental data.
Fig-4: FE model showing single and double pores Results and discussion Single pore Experimental results shows that the reduction in strength of the specimen due to a single pore is proportionalto the reduction in fracture area due to defect.
The plots are linear implying the reduction in failure stress is proportional to the reduction in the fracture area and the stress concentration effects at the hole edges are not influencing the load carrying capacity.
For the double pore cases the reduction in failure stresses are more than that of the single pore case of the same defect area.

No reduction of Dits due to the implantations is seen for any of the ions.
Here we have used low energy C, Si and N ions to tailor the interface of SiO2/4H-SiC prior to the dielectric deposition to study the influence of chemical and structural effects on electrical device data.

For too large amount of negative charge the field reduction at JTE 1 is, however, compensated by a field increase at JTE 2, which results in an earlier breakdown, as is seen in the Si low and medium case.
Computer simulations, using the data extracted from the CV measurements, indicate a possibility to tailor the interface charge and thereby improving the blocking properties of 4H-SiC BJT’s without compromising the current gain.
