Hence comes the reduction of friction loss and leakage loss.
A conclusion can be clearly drawn from Figure 5 and Figure 6 that from the comparative analysis of the external properties data of FGM green automobiles before and after SHS treatment it can be seen that both the calibration power and maximum torque of the engine increases while its minimum fuel consumption ratio decreases.

Put data of mining subsidence and layer’s data of land use into ArcGIS, then change region of mining subsidence to regions of the different deep subsidence, then intersect layer of mining subsidence with one of land use, the different deep subsidence and land use database are spatially analyzed and the different lands are found out and their areas are calculated, ArcGIS expresses the result in the way of image.
The composite analysis is based on vector data, a small amount of data calculation, accurate calculation, but the operation process is quite complicated it may take a long time to composite in a large number of factors.
As the composite of spatial data structures are vector types, the extracted polygon express predicted results fairly accurately.

So, reflected in the F-L curve is the curve "drift" and the slope of the reduction is more and more big, namely joint under the same load elongation than previously grows bigger and bigger, joint length will have a longer trend.
When the stiffness reduction of steel-cord conveyor belt joint, the tensile force is the same, the conveyer belt joint will be larger elongation.
In the running process of the system, the system will joint data real-time measured stored in the database, the belt conveyor running after a period of time, can be calculated by F-L curve called the data in the database.
Through testing equipment data further analysis calculation, prediction of complete joint fault, to avoid the occurrence of accidents.

The main advantages of using these concretes are their improved mechanical and operational properties, the relative lightness of the structures obtained, the reduction in their manufacture's labor intensity, the economy of reinforcement, and the comparative ease of creating architectural forms [4,5].
With the combined use of bentonite with Odolit-K, the value of normal density differs from the control by 24%, a more intensive reduction of the liquid phase in the cement paste is noted.

This reduction in the Mg could be due to the diffusion of Sn and Cu inside Mg.
These results are in agreement with the available diffusivity data in the literature.
It should be noted that there is also a coincide diffusion mechanism involving the diffusion of the base alloys ( e.g Ti and Mg) into the joint region that consist of Cu and Sn however there is no confirmed data that reported the diffusivity information of Ti or Mg into Sn at high temperatures such as 500 C.
The reduction of the strength for bond made at 600 C could be due to the effect of thermal softening of the magnesium alloy at high temperature which was reported in the literature [17-19].

The gas development is catalysed by oxidation-reduction reactions of iron oxides with organic impurities, oxidation of these impurities, dehydration of hydromicas and other hydrous clay minerals [5, 6].
These data are confirmed with X-ray phase analysis data (Fig. 1).
The experimental data indicate the substantial resistance of crushed ceramic materials to the leaching in acid medium.
The considerable reduction of the extent of heavy metal ions leaching from the obtained ceramic matrices is conditioned by the fact, that their baking causes salts decomposition, the heavy metals hydroxides formation, as well as their further dehydration and transformation to the more stable oxide modifications.

Then, some numerical results obtained via the proposed models are compared with available experimental data and some behavioural examples are provided.
Behavioral examples and comparison with experimental data In order to clearly describe the proposed damage model, some results are presented for a simple example case.
As shown by the figure, the numerical results are acceptably consistent with the experimental data in terms of force and deformation up to collapse.
The obtained results show that in all cases except for Case ip, the FRP-retrofitting leads to a reduction in the mean of maximum displacements with respect to the unstrengthened case, up to a maximum of 15% for Case ie.
Case i and Case e show a similar trend, though with less reduction effects than in Case ie.

The X-ray diffraction data was collected from 2θ between 20 o and 100 o with scan rate 2 oCmin-1.
The detected peaks were matched with the JCPDS data file of ZnFe2O4 (No. 22-1012) and NiFe2O4 (No.10-0325) as the plane reflection for cubic spinel phase nickel zinc ferrite.
The decreased in electrical conductivity might be attributed to the reduction of extra charge carriers contributed by Zn.
However, it must be noted that the low Seebeck coefficient and high thermal conductivity was observed when sintered at higher temperature can lead to the reduction of the figure of merit.

Moreover, minimizing rubber consumption, our research contributes to the solid waste reduction program.
By utilising our MRP procedure, the outsole rubber company can minimize the rubber material consumption and contribute to solid waste reduction.
MRP Method Firstly, we collect data from the company, which consists of the raw material used in outsole production, customer demand and also the parameter process.
The data of rubber outsole production is presented in Table 1 as below: Table 1.
Based on the data from the company, they only consider safety stock equal to 810 gr/shift that related to the maximum acceptable defect.
