Whereas support vector machine (SVM) is based on structural risk minimization principle and has very good generalization with few data samples.
Fig. 1 Plane graph of surface main buildings Measurement of vibration data In order to control the effects of blast vibration in Beijing East Road No.1 tunnel excavations, data measurement operations were carried out with seismographs device “UBOX-5016” made by Top Measurement and Control Technology Co., LTD.
If C is too small then insufficient stress will be placed on fitting the training data.
If C is too large then the algorithm will overfit the training data.
But value is too large, reduction data points fit precision.

The critical data of various indexes are different at the same class in Table 1,translate them into comparable data of columns in order to eliminate the influence and each index is dimensionless ,with the first class being the standard item, separately the various index is divided by the first index {(1,2,3,4 index score)/(the first index score)}.Quantitative score of Table 1 is proceeded with dimensionless and then get the critical whitenzation number of non-dimensional classification that can be seen in Table 2.
The sample value of original data non-dimensioned will be substituted into whitenzation function .
Data used in the paper are obtained in the way of experts’ consultant.
The process of original data is shown in Table 4 while Table 5 is the dimensionless processing of raw data.

The software we designed using the wavelet transform for signal noise reduction, and using cross-correlation method for time delay estimation and leak point location.
The data acquisition software is based on a dual-channel independent soundcard, and the wavelet denoising is implemented by LabVIEW and MATLAB mixing programming.
The sound velocity we measured in the experimental environment was about 1470m/s, this value was used in processing the following experimental data.
To study the impacts of different wavelet basis and decomposition levels on location accuracy, we randomly selected 100 data with mutations removed under the test state of 20m ~ 40m, and the results shown as in Table 2.
For comparing the location accuracy difference when we use or without use wavelet denosing, 10 group data (every group has 100 data) were selected under three test states.

It is an approach to outsource data with the aim of decreasing the data storage and reducing the management issues [21].
Main benefits of cloud computing implementation are: less infrastructure investment, convenience, flexibility, enhanced performance and cost reduction [5].
Cloud Computing System Architecture within the Precast Construction Industry Cloud computing technology sends and retrieves the data and various applications via the utilisation of internet and central remote servers including the application servers and the database server.
The integration of cloud computing, mobile clients (such as the smart mobile devices including the smartphones and tablets), servers and data center [4-6,9,19,23] and logistics management [24] could be applied for the precast supply chain management.
Furthermore, the cloud computing implementation within the precast construction industry, will deliver significant opportunities for improving the effectiveness and enhancing the appropriate information flow along with accessing to data, information and services.

In a further study, flexure on larger specimens was also simulated with a very good agreement with experimental data [7].
A value of 0.19 ± 0.02 g/cm3 was obtained, according with the foam nominal datum.
A reduction of 23% is observed in the plateau stress from room temperature to 400°C.
The increase of the plateau stress from as-cast condition to T6 heat treatment is only 24%, comparable with the reduction due to 400°C heating.

Figure 7 illustrates one of these graphs for the as-sprayed coating data's.
Heat treated at As Coat 800 °°°°C 1100°°°°C Residual stress -1181.6 -984 -910.5 Standard deviation ±173.7 ±87.4 ±101.3 The reduction in the residual stresses of the WC-Co coating by heat treatment did not reduce hardness of the coating (see figure 4) and on the contrary resulted in increase in the microhardness of the deposits.
Increasing of the heat treatment temperature from 800 to 1100 °C resulted in recrystalisation of amorphous phases and hence more reduction of the residual stresses in the deposit.

Four biological diversity indices and the Goodnight-Whitely modification index (GBI)[16] were used to assess water quality.
The pollution of Songhua River along Harbin city will be a serious threat to zoobenthos, leading to the reduction of benthic species and habitat density and the dominant species were Chironomidae larvae, L. hoffmeisteri as well as some snails.
