It was a normal probability plot that indicated the error of the data, and estimated standard deviation of the residual that measures the amount of standard deviations separating the observed and predicted values.
The data points lying on the straight line show that there was no problem with the normality of this curve.
As a histogram in Fig. 1b the results shows that the trend of the normal curve represented the accurate data.
The fit chart in Fig. 4c shows the random of the data.
The results of this experiment showed that the data were distributed as well.

Based on the characteristics of RDF data, we propose to compress RDF data.
RDF data storage, to RDF data compression, the longer URI prefix mapping table stored in the prefix.
We use LUBM generator provided data sets of different size, size of the data shown in Fig.5.
Jena and RS_Opti over 500M memory overflow data when the result cannot be obtained, and the methods used herein 500M of data on the data shown in Table 1 These experiments show that the proposed algorithm can better handle the large-scale data, the complexity of data for small queries better algorithm optimization.

By using the B-S pricing model and European carbon option trade market data, constructed a carbon option pricing model, then based on the similarity economy comparison between European Union and Jiangsu province, obtain the discounted carbon trading market price of Jiangsu area.
In short, how to take corresponding measures accorded to the clean developed mode in this region to ensure that companies have incentives to participate in emission reduction.
Tab.1 The type of CDM projects in Jiangsu Data resources : China Clean Development Mechanism database net Possessing economy foundation and resource endowment to develop low carbon economy.The current public facilities, public works and transportation infrastructure has owned strong financial attractiveness, greatly improved compared to the previous conditions.
Tab.2 The composition of energy sectors in Jiangsu in the year of 2011 Data resources: statistical yearbook in Jiangsu in the year of 2011 As of December 31,2012, Jiangsu province CERs have been issued a total of 38 projects, mainly for new energy and renewable energy aspect and HFC-23 projects, totaling 35,416,887 tons of carbon dioxide equivalent (tCO2e).
We use the two-years government bond interest in European as the risk-free rate, the data can be obtained by the Italian government bond interest rate of 4.511% in 2012.

The data was from 1980 to 2009.
For Beijing area, the adjustment of industrial structure has little affection on emission reduction, other measures such as improving energy efficiency and reducing the emission from consumption activities should be taken to achieve the emission reduction targets.
Then the traditional and improved models are presented as well as the data selection in section 3.
Model and data declaration Cubic form of traditional CKC is formula 1 as followed:
(5) Data in this article were from Beijing Statistics Bureau and China Energy Statistical Yearbook.

Furthermore, experiment results based on the measurement data show that the wavelet denoising method is more efficient in some aspects such as the accuracy of identification and SSE.
In the load modeling processing, due to the natural load is changeable at anytime and the measurement instruments have measure error as well as the data transforming and compressing, the measurement data inevitably include disturbance and noise.
Preprocess the original measurement data, including voltage signal V(t), active signal P(t).
After preprocessing of the signal, make difference of the voltage data to confirm the step point of the voltage variable before select a suitable threshold value T.

Therefore, potentials of data analyzation and usage, e.g. information about data consistency and data dependency or inference possibilities are kept unexploited.
This allows the retrieval of data by querying against pre-defined table columns representing features of a data set.
Short-term measures that serve to remedy a deviation of a defined set point as well as measures for the long-term reduction of resource and energy requirements can be stored and assigned.
Meta data can be subdivided into administrative data, descriptive data, structural data as well as technical data.
Administrative meta data describe all modalities of data manipulation.

In addition, the effect of the reduction was considered (the final thickness of the pipe wall varied from 2 to 3 mm).
Since the greatest amount of experimental data on residual stresses concerns cold drawing of bars and wire, it is also convenient to consider the case of rod drawing as a test problem.
The smaller the reduction, the lower the residual stresses.
In case if reduction is increased, the residual stresses increase.
Comparing the calculated data with experimental ones obtained from the literature, we can note qualitatively similar patterns of residual stress distribution along the cross-section of cold-drawn rods.

Comparative Study on Data Editing Techniques for Fatigue Time Series Signals Z.
This paper presents the comparative study on three types of fatigue data editing technique for summarising long records of fatigue data.
Experimentally, the data was collected for 60 seconds at sampling rate of 500Hz, which gave 30, 000 discrete data points.
Using this approach, large amount of significant fatigue data time series signals are retained, and thus shortened loading signals consist of significant amounts of data is produced.
In the presented case study data, i.e., by using different approachs, the pavé edited signal shows a reductions from the original signal.
