The powder diffraction data were collected between 375 K and 975 K in steps of approximately 8 K/5 min. and evaluated by Rietveld refinements.
The powder diffraction data were collected at Beamline I711 of the MAX-II synchrotron in Lund, Sweden [3].
The samples were packed in 0.3 mm quartz capillaries, open in both ends, and kept spinning during the 5 min data accumulations [4].

And then using the selected data gear is to be designed based on compressive and the bending strength using general procedure for the design of gears.
, two stage reduction spur gears are used as the reduction cannot be achieved by single reduction using spurs.
Therefore the module chosen is correct. 3 Results and discussions The gear is modelled using the software with data specified in the previous chapter.

Cu-supported on Acid-treated Sepiolite: Characterization and Selective Catalytic Reduction (SCR) of NO by Propene Yunfang Qi, Yang Li, Zhihao Zhang, Lisha Liu, Qing Ye*, Dao Wang Key Laboratory of Beijing on Regional Air Pollution Control, College of Environmental and Energy Engineering, Beijing University of Technology, Beijing 100124, China a E-mail address: yeqing@bjut.edu.cn Keywords: Selective Catalytic Reduction of NO by Propylene; sepiolite; Cu Abstract.
Selective catalytic reduction with hydrocarbons is one of the most extended and efficient commercial DeNOx processes for nitric oxide removal from stationary sources.
Reports on a large number of catalysts for the selective catalytic reduction (SCR) have appeared since 1990, being the majority of these catalysts ion exchanged zeolites [1].
The pattern of the H2-TPR spectra of Cu/H-Sep was decomposed in three peaks with temperature at ca. 220, 260 and 440 oC, corresponding to the multiple reduction of Cu2+ and Cu+ species.

In cork stopper production SMED resulted in a 43% overall reduction in changeover time.
Step 1 was done together with step 6, and step 3 was done together with step 4, which resulted in a time reduction of 9.35 minutes.
Design and create a new bypass system to reduce the time required to bypass PVC, resulting in a reduction in work time.
Data was collected and timing was recorded for five instances after the improvements were made.
By analyzing the data and implementing a system to sustain positive outcomes, the standardized procedures and implementation methods that have proven effective are adopted as work standards by the management team and provide the standard documents for training the relevant personnel.

Accuracy of data reduction stage was lowly, the reason was mainly software and human aspects.
It had resulted error or distortion in reduction of data.
As a result, high quality data and high precision data reduction need a set of feasible solutions.
(3) Data reduction was completed by grid processing command and processing command.
The method can effectively solve key problems such as complicated product structure design, data loss, data reduction inaccurately.

A comparison on grounding resistance value for copper rod, steel rod and galvanized iron rod was examined and the selection of the best grounding rod was determined from the experimental data.
Based on experiment data, the performance for each grounding rod are compared and analyzed.
The formula for percentage of reduction is given as in Eq.1
The percentage of reduction for the parallel installation system between three types of rod clearly shows that the peak of reduction is at day 2, which the reduction for copper is 29%, galvanized iron 14% and steel 18%.
Discussion Based on the data that collected for both parallel and single grounding system, it shows that copper rod have the highest resistance value compared to steel and galvanized iron.

In order to evaluate and mitigate the province from the agricultural natural calamities, the panel data from 1990-2012 of four agricultural natural disasters covered and affected areas are analyzed.
These data refers to the total of the above four main kinds of disasters, therefore other agricultural damages have not been included, for example typhoon, plant diseases, insect attacks, grass evils, rodents and rat harm, etc.
With the statistical data and information, we can give an initial analysis for the cases of natural disaster reduction and prevention.
DCT DC DAT DA Figure 4 Floods According to average disasters covered and affected areas data in table 1, the flood disturbed the province agriculture after drought and wind hail.

Another one is based on the use of test data compression (TDC) techniques, which has been at the forefront of solutions to reduce test costs through reduction in tester storage and test application time[1~16].
A method called COMPACT is presented in [10], the key idea of COMPACT is to employ two data compression schemes, run-length coding for data with low activity and GZIP for data with high activity.
In the paper, we analyze the application condition of a compression algorithm for test data, and denote a test data compression method RLE-G, Run Length Encoding based on Golomb coding, that provide significant compression for pre-computed test sets and lead to considerable reduction in testing time, it has the excellent advantages of high compression ratio and low overhead.
As the original test data are stored on the ATE side, and the test data stored in memory of the ATE in compressed (encoded) form (TE).
Therefore, to reduce the data expansion and get highest compression efficiency, the analysis of the overall data coding results is needed.
