Spending a lot of time to account the logistic cost data can only play a role in the financial budget, and cost accounting is just to know how much the logistic is, which does not apply the logistic cost data.
Then the data base will be used [6].
It is assumed that there are appraisable schemes and indexes, and there are primitive data.
The primitive data is shown in Table 1.
The data are listed in tables 2 and 3 respectively.

The best sagging resistance is available when the percentage reduction of final pass is 25%~35%.
Cold-rolled composite, the first pass reduction rate control in 20% to 60% after the single pass reduction rate was controlled at 20% to 30%.
Final finish rolling reduction rate was controlled at 15% ~ 60%.
Graph data show that the annealing temperature below 400 ℃, the sagging value of the composite foil can be maintained under the 8mm product standards, and only above 320 ℃ annealing composite foil to be able to fully soften.

Wavelet Transform Based 3D Scattered Data Processing in Binocular Micro Stereovision System C.
Keywords: wavelets transform, scattered data, edge extraction, median filter Abstract.
In micro stereovision system, false matching due to the randomicity of image signal makes 3D reconstruction data contain a large amount of abnormal data in the form of noise (pulse noise, Gauss noise).
Experimental results indicate that the method proposed is effective to removing abnormal data from the 3D reconstructed data and enables 3D measurement position accuracy to reach 3 mµ .
All these drawbacks make the 3D shape reconstruction data contain a large amount of abnormal points.

Green-efficiency Assessment of Chinese Industry Based on Principal Component Analysis and Super-efficiency Data Envelopment Analysis Ruijie LIU1, Zhihui ZHANG1 1 Dept of Construction Management, Tsinghua University, Beijing, China Keywords: Industry, Principal Component Analysis, Super-efficiency Data Envelopment Analysis, Green-efficiency Assessment Abstract.
Evaluation Methods Super-efficiency Data Envelopment Analysis.
Adopting principal component analysis in dimension reduction can overcome the limitations of DEA input-output indicators, make full use of available data, and avoid subjective factors in the selection of indicators.
As the DEA model requires the input-output data to be positive number, and a negative number will exist in the principal component analysis result, so there is a need of conversion to turn all the data positive and ensure the relative gap between data of different years unchanged.
By utilizing the data of Chinese industrial input-output indicators in Table 2 as an example, the super-efficiency DEA model calculates the Chinese industrial green efficiency.

Therefore, it preserves the variation of data and characterizes the global Euclidean geometric structure of data, which is suitable for linearly separable data analysis [2-4].
Fig. 1 Distribution of nonlinear data points Motivated by manifold learning approaches, a novel method, called local variation projection (LVP), is proposed for dimensionality reduction.
LVP Learning the variation Given training data matrix , denotes the th data; the number of training data.
Feature Extraction Criterion Our aim is to seek the projection which makes the projected data preserve the variation among nearby data.
Although these manifold learning approaches preserves the local geometric structure of data and have been shown to be useful for dimensionality reduction of image, they ignore the variation of data, which is important to avoid the over-fitting in LPP and NPE.

The effectiveness of noise reduction of the noise barrier can be affected by many factors.
The data indicates that noise reduction results of noise barrier of the viaduct are generally relatively lower than expected.
The effects of the viaduct and noise barrier vibration on the noise reduction of the noise barrier are studied using the combination of the test data and a real viaduct and noise barrier.
The analysis of the noise reduction amount of the noise barrier.
Therefore, the noise reduction result of the noise barrier reduce 2.3dBA because of the influence of viaduct sound radiation, the impact on noise reduction result of the noise barrier is remarkable.
