Degradation of Azo Dyes by the Reduction and Oxidation with Nano Sized Zero Valented Iron B.H.
Pre-reduction by nZVI could convert azo dye to products whose oxidation is more degradable and therefore enhances the removal efficiency.
The successful use of ZVI has been reported to decolorize azo dye solution by reduction of the -N=N- bond at the iron surface [2,3,4,5].
The laboratory synthesized nZVI used in this study had the specific surface area of 27.9m2/g, which is smaller than the data reported in the literature.
Compared to various H2O2 dosages, pre-reduction of Orange II with nZVI enhanced the TOC removal by 5~15%.

The validity of the proposed approach is demonstrated using electronic stock data extracted from the financial database maintained by the Taiwan Economic Journal (TEJ).
Data Extraction In the present study, the performance of the proposed stock selection mechanism was evaluated using electronic stock data extracted from the TEJ database [11] over the period extending from the first quarter of 1998 to 2/27/2009. 4.
Step 1: Data collection and attribute determination In each quarter, the 53 attributes of each specified stock item within the TEJ database are collected automatically, and the user is given the opportunity to modify the choice of financial ratios used for attribute reduction in the initial GRA process, to select a new GRA model for attribute reduction purposes, and to modify the decision-making attributes used to filter the stocks in the lower approximate set.
Step 2: Data preprocessing Having collected the relevant financial data for each quarterly period, a basic pre-processing operation is performed to improve the efficiency of the GRA attribute reduction process.

All partial data affected by the presence of other vehicles was removed to maintain the most consistent experimental conditions.
Data Manipulation Data that affected the driver's physiological and psychological and driving behavior characteristics in non-tunnel lighting conditions was excluded in the 50 groups of sample data obtained in the experiments and from the 15 groups of samples in the test of car drivers in free-flow traffic conditions.
Based upon the calculation principle of the representative value, we calculated the 15 data groups shown in Table3.

This paper put forward the collecting method of reliability failure data and data preprocessing method including data cleaning and data analysis method, which based on the analysis of the importance and the source of failure data in the software reliability testing and the classification of software failure data.
Finally through an example, it displayed the reduction of data noises and the promotion of data quality which produced by the preprocessing methods.
And the failure data can be divided into complete failure data and incomplete failure data.
One is the standard to collect data (i.e. what kinds of data should be collected), the other is the specified process of data collection (i.e. how to collect data).
Exposure analysis In the process of collecting software failure data, it is possible to lose some data and bring in some useless data meanwhile.

Investigation of Effects of Changing Blade Position and Size Reduction on Performance of Axial Pump used as Turbine 1A.
In this present work, an axial pump is simulated in reverse mode by computational fluid dynamics using different turbulence models and Characteristic curves of the reverse pump are obtained for each turbulence model and are compared with experimental data.
Comparison of turbulence models results The results of all models are compared with experimental data and are shown in Figs. 3-5.
Impeller size reduction increases head, but decreases flow rates and maximum efficiency.

For this paper, we use the Co loading values measured by EDS analysis in the data analysis and discussion.
Fig. 3 Koutecky-Levich plots for the ORR on CoNC coated glassy carbon electrodes Fig. 3 shows the Koutecky-Levich plots for the ORR data taken at the potential from -0.1 to 0.2 V.
The data comes from the current-potential curves (Fig. 2) obtained using CoNC2.
Its approach contrasts with the theoretical plots for 2- and 4-electron reduction reaction in Fig. 3.
It could be suggested that the CoNC2 can alter the ORR reaction mechanism via both the 2-electron reduction reaction and the 4-electron reduction reaction. 2.3 Scanning electron microscopy measurement Fig. 4 shows SEM images of a sample of CoNC2 catalyst magnified 5000 and 10000 times.

Strengthen the network loss management, implementation of loss reduction measures, has become an important power supply enterprise content management one.
The Theoretical Calculation of Net Loss Distribution network is designed as closed-loop, the operation mode of open-loop characteristics, the actual operation of the distribution network mostly radial, the detailed information of each load point and component data is should be collected and collated in the distribute network ,but it is extremely difficult, also a lack of trend analysis for the load required data.
To ascertain the reasons for lifting line loss, power loss reduction and management measures developed, in net loss management departments, data would be collected carefully, want to give an accurate and timely data and statistics[3]
Reactive power compensation of power supply enterprises and users combined in the power compensation. 5) Loss Reduction and regulator combined to derogate, account regulator taken, especially for long lines, many branches, load dispersion, low power factor of the rural distribution network loss reduction is the main purpose

An experimental and numerical investigation into forming force reduction in precision gear forging Nicholas J.
As maximum force, along with workpiece size are the two key specifications for industrial forging presses, a reduction in the load required to fully fill a die translates directly to a reduction in the capital investment cost of a production process.
Experimental true stress-plastic strain data is used up to a plastic strain of ε = 0.401, and thereafter the properties are represented using the power-law equation, σ=σy+Kεpn, where: σy=7MPa, K = 96.63 MPa, and n=0.3955.
In order to describe work hardening for strains greater than those obtained in the experiment (ε = 0.401), experimental data was extrapolated to ε = 4 using a power law model with constants: K = 96.63 MPa, and n=0.3955.
