Most scholars study in the pilot study stage, heavy workload, cost expensive, the resulting data often have significant limitations.
Thus, according to the example of the original test data, using empirical formula to calculate the experience of the three cutting force values were: Fz equal to 3774.62N, Fy equal to 1509.85N, Fx equal to 1132.39N.
The minimum stress along the flank, in contact with the end of the stress, a total reduction of only 20% to 30%, in a distance equal to the length of exposure, the stress drop of the rake face 3/5 -2/3 times.

Introduction Systemic and topical capsaicin administration produce a reversible anti-inflammatory action by the inactivation of the neuropeptide release from peripheral nerve endings, therefore these mechanisms account for reduction of neurogenic inflammation.
All formula showed the newtonian flow (data not shown).
When these solutions contacted with phosphate buffer pH 6.8 the sol state suddently transformed into turbid gel at the interface (data not shown).

The abductive network is then applied to synthesize the data sets obtained from the numerical simulation, and a prediction model is established ultimately.
Fig.1 show the load predicted by the FEM is closer to the experimental data than the prediction by upper-bond method of Choi et al [1].
The abductive network is then applied to synthesize the data sets obtained from the numerical simulation, and a prediction model is established ultimately.
Base on the training database regarding to process parameters, ln(Pmax) and w0.5, shown in Table 1, the abductive networks with a criterion of minimum square error can be developed for predicting ln(Pmax) and w0.5 under a suitable range of process 0.0 10.0 20.0 30.0 40.0 Height Reduction [ % ] 0.0 20.0 40.0 60.0 80.0 100.0 120.0 Load [ KN * 10 ] Current simulation Experimental data of Choi et. al [7] Theoretical results of Choi et. al [7] Simulation results of Yang [12] parameters.

To find out the necessary diffusion parameters, the data were fitted with numerical optimisation.
It clearly indicates that the fit describes well the experimental data.
This ferromagnetic phase fraction can be measured and the corresponding data is shown in Table 3.
The experimental data were fitted by the Arrhenius equation (Eq. 6).
Table 4 summarises the calculated data for the investigated material states.

According to the empirical data [4-7], various carbon emission coefficients of carbon sources as in Table 1.
statistical standards, the textile carbon emission in Henan Province can not be directly compare with other provinces, but can compare the energy consumption (Million tons standard coal), then you can know the probably situation of carbon emission, each provincial energy consumption statistics data basically from 2007, therefore, this article only compare the two years data from 2007 to 2008.
The energy consumption intensity comparison in industry of Henan in 2008 Data: Henan Statistical Yearbook (2009), where the added value is industrial enterprises above designated size.
Comparison Characteristics in Henan The result in Fig. 1 show that, compared with the other three provinces, the energy consumption of textile in Henan in 2007 was less than Hunan and Jiangxi, however, the data in 2008 was 3 times in Jiangxi.

Fixed several discharge conditions discharge, discharge data obtained, and then change the fixed discharge conditions, a series of data are then used as training samples to train the neural network.
First of all, all the data obtained are used to train the network, and the error is into the flat area after training network about 100.
After training completely network, the data during validating data extracting the pulse process parameters is entered into the network to obtain the output predicting value, so it is referred as predicting SOC. 1.
Comparing the predicted and experimental values Since the data are more, the maximum absolute error is less than 5%.

The RFID transponder saves data in the chip, keeping away from stain and damage.
The data is password-protected and difficult to be falsified, which ensure its security.
The RFID reader will then read and decode the data, and send it to the higher level system through the communication interfaces[7].
When the battery compartment is in the induction area of the RFID reader, the reader will read ID information on the tag, communicate data with upper-level management unit, upload the collected ID data, execute the command issued by higher level management unit, and finally upload the ID information of the battery compartment to the monitoring system.
The uploaded data is the basis of unified battery compartment management.

Large straightness error may result in the life reduction wear and rotational run-out.
Practical examples For comparative purposes, the measured data available in the literature [7] are selected.
Table 1 (a) and (b) show the measured data of the planar straightness error of a linear stage.
It is observed from table 3 that, although there is a disparity in the choice of the initial region, the evaluation results is not much difference for the same data.
For calculating convenience, take two endpoints of the measured data as the initial reference point and the initial regionis more than two times estimation error value of the measured.
