Fig. 4 X-ray diffraction data for the mixture of Fe2O3-Ca MA powders ball-milled for various time intervals and subsequently heat treated up to 600°C.
Fig. 4 shows the X-ray diffraction data for the mixture of Fe2O3-Ca MA powders ball-milled for various time intervals and subsequently heat treated up to 600°C.
Hence, the magnetic data of Fe2O3-Ca MA powders can supply a better understanding of the evidences for the solid state reduction process of Fe2O3-Ca system, as well as the amount of magnetic phase and microstructures.
The X-ray diffraction and magnetic data have been discussed simultaneously in order to achieve a better understanding of the solid state reduction induced by MA.

Furthermore, According to the historical data of civil aviation industry development, the feasibility and prospect of three solutions are analyzed with the method of AHP.
With the Copenhagen conference held in Dec 2009 and EUETS started on January 1 2010, aviation emission reduction draws intensive attentions around the world.
The prediction of future air transportation demand indicates: the goal of aviation emission reduction cannot be reached with only one of above solutions.
At least according to current research, it is the only effective way to validly mitigate jet-fuel crisis and aviation emission reduction.

The results were compared with the statistical data derived from regular use of vehicles equipped with such a system. 1.
Potential reduction in CO2 emissions Potential reduction in CO2 emissions are discussed by way of an analysis for selected traffic conditions in the city of Gdansk and in its suburbs.
The data obtained from the simulation were subsequently compared with the results of certification tests provided by the Start-Stop system manufacturers.
Based on the registered 6.5 million trips, an average reduction in fuel consumption has been calculated, which directly gives the reduction in CO2 emissions of around 4%.
Statistical data derived from regular use of vehicles equipped with Start-Stop system (Fig. 11) show much less positive results but they are calculated for average operating conditions of vehicles operating in urban center and beyond.

Then, the Hadamard transform is performed to reduce the correlation of the input data sequences.
Finally, data signals are successfully received after the P/S conversion.
CCDF denotes the probability that the PAPR of a data block exceeds the threshold value.
PAPR Reduction Technique Hadamard Transform is a precoding technique that reduces the correlation of the input data.
The data sequencesafter the Hadamard transform can be represented as: (5) Partial Transmit Sequence Scheme.In the PTS scheme, an input data block of N symbols is partitioned into several disjoint subblocks.

Big data-driven hybrid model for operation optimization of thermal power units 3.1.
How to analyze these data effectively is clearly of importance.
With the exergy analysis in Section 2, big data analytics emphasis the huge volume of data and imply that the collected data set covers almost the whole population as well.
In this paper fuzzy rough set (FRS) is selected to perform big data analytics.

Algorithm based on wavelet was studied for noise reduction of data cloud, and one volume calculation model was raised.
Wavelet and Riemann algorithms were used to reduce noise of measured data and volume calculation.
Comparison Experiment And Data Analysis To verify the measuring method discussed above, comparison experiment system was designed.
Because the data from laser scanning method is arranged by linear array, the B-spline or NURBS was used to reconstruct the surface of horizontal tank shell.
Zhao: 3D Laser Scanner Data Acquisition System Developed (In Chinese).

As one of the efficient means of data acquisition, remote sensing data play an important role in many areas of life through the development of technology and the improvement of spatial resolution.
In this paper, the application of remote sensing data on dynamic monitoring of coastline in the Yellow River Delta was analyzed.
Data and Methods The data used in this paper are fourteen scenes remote sensing images of the Yellow River delta from 1996 to 2011, which is shown in Table 1 and 1:50,000 scale topographic map of Dongying.
Fig. 2 Location of the study area (1) Study area of the Diaokou Estuary The length of the coastline in the Diaokou part has a linear reduction during 14 years from 1996 to 2011, from 78.78km in 1996 to 63.33km in 2011, with an average reduction rate in 0.96km/a.
(2) Through interpreted the multi-temporal remote sensing data could get the exact image of coastline, and provided data support for coastline changing trends research

Climate warming is supported by clear scientific data, and the rapid changing since 1950 is unprecedented for millennium.
Statistical data as of May 1, 2014 [11] shows that the number of Chinese CDM projects registered in the UNFCCC is totally 3749, accounting for 50.11% of the global number; the annual carbon emission reductions arising from the first crediting period is up to 594333 ktCO2e, accounting for 60.88% of global CDM market; up to the end of 2012, it had produced emission reductions of 1297787 ktCO2e, accounting for 58.43% of the total emission reduction generated by global CDM projects, and it will generate 5956304 ktCO2e emission reductions by 2020, which accounts for 62.41% of the global number.
The The enhanced awareness of energy conservation and emission reduction.
The emission reduction quota forms the Chinese certified emissions reductions (CCER).
The overlapping and interaction of these policies, some of which still under progress, on the one hand, provide foundations, infrastructure, capacity, and data basis for ETS in China, and on the other hand, offer some challenges (e.g., multiple targets such as energy, renewable, carbon etc.) that might lead to confusion for local governments and enterprises, overlapping of mitigation efforts and multiple trading commodities (with potential of double accounting) [16].

All catalysts are prepared by impregnation reduction method and characterized by XRD and TEM.
Catalyst Ag/C has higher catalytic activity to H2O2 electro-reduction [7].
Preparation of electro-catalysts 10% Ag/C catalysts was prepared by impregnation-reduction method.
