Friction coefficient was directly evaluated by the apparatus and data on the wear were obtained by measuring the loss of weight of the samples (parallelepipeds with hemispherical head).
Introduction Wear [1-2] is a major cause of machines performance reduction, so any reduction of this phenomenon is advantageous.
By the obtained data it was carried out a values rearrangement.

FT-IR spectra confirmed the formation of cellulose-GMA and XRD data showed a slight decrease in the crystallinity of cellulose after GMA addition from 6.98% to 6.02%, 5.57%, and 5.83% for cellulose-GMA prepared using 15%, 20%, and 25% of GMA, respectively.
The sample weight reduction obtained for cellulose was 70.029%, while grafting cellulose 15, 20 and 25% GMA experienced a weight reduction of 90.347, 94.116 and 91.702% respectively. 20% GMA grafted cellulose has the highest weight loss, so the thermal resistance of cellulose increases.
XRD data shows that GMA grafted cellulose experienced a slight decrease in crystallinity which implies GMA only slightly affects the cellulose structure, although disorientation of the cellulose structure occurs.

The proposed QNN forecastig model is tested for certain province load data.
Let denote by ijx the jth component of the ith data pair.
Therefore, the load influential factors can be further reduced without loss most information of original data.
The data used in the simulation is the actual load power data of Hebei Province in 2004.

Fig. 2 presents data related to the types of human errors reported in accident reports [11].
Table 1.ENDSLEY’S SA ERROR TAXONOMY Level 1: Failure to correctly perceive information such as: Ø Data not available Ø Data hard to discriminate or detect Ø Failure to monitor or observe data Ø Misperception of data Level 2: Failure to correctly integrate or comprehend information such as: Ø Lack of poor mental model Ø Use of incorrect model Ø Over reliance on default values Ø Memory loss Level 3:Failure to project future actions or state of the system such as: Ø Overprojection of current trends For instance, in an aircraft environment, operators must aware of critical flight parameters, the states of their on-broad system, their own location and the location of important reference points and terrain, and the location of other aircraft along with relevant flight parameters and characteristics.
Thus, although they were aware of low level data (effectively monitoring the system), they has less comprehension of what the data meant in relation to operational goals.
In addition, there is a tendency for some displays to eliminate raw system data, in favor of processed, integrated information.
Important information as to the source of information, its reliability, or the value of constituent data underlying the integrated information may be unavailable.

This system has poor portability and cannot adapt to large scale data processing.
The MVC(model view control) model separates the layer of data access and data performance, provides better decoupling and has obvious advantages in achieving multi-tier Web applications.
Fig. 2 Software Architecture In the first place, the data table and their relationship must be determined in the entity layer, then the Hibernate Mapping file and entity class which must be consistent with data table be written.
The business logic be written, also it can get real-time data by Coherence in this layer.
These statistical data mainly consist of by data, by charging facilities, by vehicle and statistical curve, and so on.

Finally, measurement results are validated based on the known data.
It is noted that most of the filters help noise reduction but lead to the loss of edge strength in the meantime.

The PLC is responsible for the data collection and automatic control, while the PC is responsible for the surveillance of FGD system operation and the data processing through mutual communications between PC and PLC, which realizes the communication between human and machine and ensures the safe, stable and economic operation of the FGD system.
In order to achieve the SO2 emission reduction targets, country has developed a series of environmental protection measures.
Fig. 3 Power supply circuit 3.4 data acquisition circuit According to the control system requirements, the main desulfurization system data is collected as follows: pH of the slurry, dust concentration, gas pressure and gas temperature.
Meanwhile, on-site data acquisition circuit and the interference of power supply circuit were designed.

Neugebauer and Stoll [4] had some experiments in UAD of Aluminum alloys and demonstrated that reduction of axial and radial force are possible and this will lead to an increase in tool life 20 times more than conventional cutting.
In all the diagrams, lines were formed directly from the data and finally second-order polynomial equation was extracted.
Some authors [9] pointed out this probability as a result of reduction in sliding coefficient of friction in cutting zone while some others [10] have studied the ultrasonic assisted methods as a main approach for reducing the temperature of the cutting zone.
Observing all the diagrams extracted from experimental data confirmed this fact.

But seldom consider to achieve the emission reduction targets by making adjustments in the operational decisions of production, transportation and storage, etc.
Although at present many enterprises in the world also take the corresponding measures to reduce their carbon emissions, but most of them take the measures of increasing productivity, using new energy, and employing low-carbon facilities to achieve carbon reduction.
And the management of the carbon footprint is a kind of effective means of emission reduction.
In the the process of numetrical simulation, to the range of values in [9000,19500], in the context of the access to data for 22 spacing of 500, and these data after solving equations with Lingo11.0, followed by partial solutions are shown in Table 1.

But there is no sign to indicate the imbalance and deformation of whole slope with a reduction of whole steadiness to some extent.
The deformed body is immersed in water so that the weight of the soil increased and the indicator of anti-shear decreased, which resulted in the reduction of anti-sliding and the sliding of the deformed body.
The designed residual thrust adopted supporting and retaining residual thrust, stability coefficient in rainfall Kf=1.20, stability coefficient in nature Kf=1.30 and the higher data in residual thrust as the designed data.[7-9] Fig.6.
Meanwhile, we make sure the hazard area are not enlarged or the new hazard happened, which were caused by the reduction of load before the expressway subgrade and protective facilities, the temporary treatment measures of sprayed concrete sealing is adopted in the cleaning slope.
