For an optimal reduction of the size of the model the CMS with reduction of interface dof is used.
This coupling methodological approach is used on one hand to reduce the size of the model and on the other hand to analyze the structures where the data on the uncertainties are limited enough.
Convex models which are adapted to the structures where the data on the uncertainties are limited enough are defined as the distance between the nominal values of the parameters and what we wish to determine, the uncertainties, to satisfy a given criterion of conception.

With regard to this the integration of adequate energy data into factory planning and design requires efficient data acquisition strategies depending on the prevailing purpose.
Therefore the general impact of energy data on factory planning is shown.
They usually refer to insecurities in metered data, the corresponding and required accuracy of measuring and the data transmission [7].
The use of measured data, on the other hand, scales with the required level of detail, i.e. the data requirements depend on the granularity of the curves to be used in the prognosis.
Means of energy data acquisition.

By making use of the developed strength reduction finite element codes based on which the matric suction can be considered, the sliding mechanism of the Down TuDiLing slope is analyzed.
The concept of strength reduction finite element method (FEM) was firstly proposed by Zienkiewicz et al[2], then Ugai and Griffths et al propelled the development and application [3,4].
Considering the influence of the non-uniform distribution of matric suction on the unsaturated soil slope stability, the theory and numerical implementation method of the unsaturated soil slope stability was discussed based on the strength reduction FEM, and thereby the strength reduction FEM was introduced into the stability analyses of the unsaturated soil slope [5].
In order to discuss its instability mechanism, the stability of the down TuDiLing slope is analyzed by the strength reduction FEM.
According to the geological exploration data, the Down TuDiLing slope is an old landslide along the bedrock.

From this data, the reduction potentials were determined for each metal, finding the values of -0.0024, -1.1274 and -0.5892 V vs calomel for Cu, Ni and Zn, respectively.
Displacement in the reduction potential with the increase of the metal concentration in the leaching solution was observed.
Concentrations were calculated for each metal in order to produce the data needed in the thermodynamic study using Pourbaix type diagrams, by the Hydra/Medusa software [13] and to evaluate the possibility for the selective metal recovery by electrochemical methods.
From the above diagrams, it was possible to observe the influence of the concentration of each metal on the reduction potential.
Reduction potential values determined for the electrodeposition of leached metals.

The constitutive relationship of alloy GH706 has been established by linear regression analysis of the experimental data taken from the Arrhenius equations as a model.
During the compression, the load-stroke data were collected through both displacement sensor and pressure sensor and then were used to extrapolate the allowable reduction of the trail ingot.
The material constants of the constitutive equation can be evaluated from the experimental stress-strain data obtained from hot compression tests.
By using the flow stress data for the experiments as shown in Fig.2, at the peak strain, the values ofn1 and β are obtained as 4.9322 and 0.03286, respectively.
By taking the natural logarithm of Eq. (3), lnsinhασ=QRn1T+1nlnε-1nlnA (6) the parameters A, n and Q are easy to be determined from the experimental stress-strain data obtained at different strain rates and temperatures by linear fitting method.

Main part of preparation work is simplification of 3D-CAD data to decrease mesh scale and without impacting the solution accuracy.

The purpose of this study is reduction of period to create CAE model from 3D-CAD data.

Partially missing or blurring attribute values make data become incomplete during collecting data.
First algorithm divided the data set into a complete data set and non complete data set, and then the complete data set was clustered using the affinity propagation clustering algorithm, incomplete data according to the design method of the similarity metric is divided into the corresponding cluster.
Introduction Clustering analysis is an important method in data mining field, when clustering incomplete data, due to the presence of missing data, the clustering result is obviously reduced.
The intuition of these strategies is discarding missing data, only clustering the complete data.

Analysis of Data Center Power System Hui Song1, a, Zhitan Wang2, b 1Jilin Technology College of Electronic Information, Jilin 132021, China 2Jilin Data Center of Petrochina, Jilin 132000, China asonghay@sohu.com, b36910008@qq.com Keywords: The power system Data Center diesel generator UPS SVG Abstract: Data center presented in this paper, has a high requirement on the power supply system, that needs emergency power supply, SVG compensation device, large diesel generator set, two lines of mains large capacity UPS and other electric equipments.
Data center interrupt is not allowed in most of its load, especially load cabinet once interrupted, is likely to cause "terminal system", "important production data" and other key cabinet data loss, the loss is immeasurable.
And huge data center generator capacity, the basic unit can take up all load data center, and the great amount of oil required, noise is bigger, need to increase the outdoor storage tanks and noise reduction device.
In order to ensure the data center of power supply reliability, reduce interference, set up the data center dedicated to match/substation and power supply equipment, data center substation in the post room module layout, shortening the distance between the power supply as far as possible, reduce the low voltage line loss.
