The ecosystem area of the region investigated is represented by the data of the TM image made in 1990 and 2000 and CBERS image data in 2005.
Different processing modes are used for processing the data source of different periods.
The image data of1990 and 2005 are rectified on the basis of TM image data of 2000, and the mean position error is controlled within two pixels.
Thus, dynamic data of land use during different periods is obtained.
At the same time, the data of ecosystem area in 1990, 2000 and 2005 are obtained, too.

As an effective method for data analysis, the POD methodology has been widely used for a broad range of applications, including reduced order model (ROM) construction, data reconstruction, image processing and pattern recognition[1~7].
Proper Orthogonal Decomposition (POD) The basic idea of POD is to obtain the optimal subspace with order m by using sample data (snapshot) xk derived from n order data space (mThe results shown in Fig. 2 are in good agreement with experiment data.

H2 consumption and Tmax (temperature of maximum of the reduction profile) positions were recorded by a TCD.
Before analysis, an pre-reduction of CuO phase to Cu0 was performed in a flow mixture of 5%H2-N2, raising the temperature at a heating rate of 10 ℃/min from room temperature up to 290 ℃.
Cu0 surface area was calculated from N2O decomposition data using the following equation .
Additionally, the reduction profiles are unimodal curves, indicating the reduced material is only CuO because ZnO would be reduced in H2 atmosphere above 600 ℃.
Additionally, (CuZn)5(OH)6CO3 in the precursors of Cu catalysts leads to more active Cu0 compared with the other precursors after calcination and reduction.

BATC survey data of 15 intermediate-band filters
offer excellent opportunity to study low spectral resolution SED for thousands of point sources in the
field simultaneously.
However, they have much superior photometric accuracy than spectroscopic data and still represent general outlines of optical SEDs.
Title of Publication (to be inserted by the publisher) BATC Multiband Data The BATC (Beijing-Arizona-Taipei-Connecticut) color survey is optical imaging survey for approximately 500 target fields [2].
The left panel shows detailed spectra for each spectral type and the right panel is for BATC SEDs Data Reduction In order to sample faintest sources at an increased S/N, we combined hundreds of images from the same filter.
The BATC data of multiple intermediate filters are indeed useful in constructing SED curves for many thousands of sources accurately.

In the present study determines the best pH range, to optimize the phenomenon of adsorption, and evaluates the reduction of hexavalent chromium and the removal of organic matter in synthetic samples, using a reactor with glass plate impregnated with TiO2 and making use of solar radiation.
With this energy absorption there is the polarization of TiO2 molecule, the positive side (also known as the valence band) form hydroxyl radicals (from hydroxyls that are adsorbed on the surface of the photocatalyst), which mineralize organic matter and the negative side (it called the conduction band) promotes the reduction of positive compounds such as Cr (VI) to Cr(III) [5,6].
In this paper, it was studied, the best pH range, for the adsorption phenomenon and it was evaluated the quantitative reduction of Cr (VI) and organic matter in aqueous solution by heterogeneous photocatalysis.
Results and discussion Group I results The figure 2 shows data from the experiments performed at acidic pH.
In figure 5 it observes the values of removing organic matter from the data of COD.

The aim of this paper is to introduce a new design as well as to compare the stiffness, load capacity and weight reduction of composite material with that of steel leaf spring.
In addition, steel spring causes a reduction in the level of comfort provided, due to the continuous running of the small loader car.
In order to obtain great weight reduction, improve comfort ride quality and safety for the passenger, the present paper is mainly focused on the implementation of composite materials by replacing conventional steel leaf spring.
Within the limits of the physical problem, the processing of the data is usually done.
While the post processing offers information for acceptance or rejecting of the data analysis of the model [8].
