Data on physicochemical parameters of the choline chloride-urea system are provided in work [15].
This data allows predicting MV2+ behavior as mediator for the cobalt electrolyte.
The data obtained after potentiostatic reduction at -0.8 V (potential of methylviologen reduction) are presented in fig. 4.
Difference between peaks c and d is approximately 150 mV that is in good agreement with data obtained above via investigation of cobalt reduction process.
These data allows concluding that in the system containing cobalt sulfate and methylviologen dichloride reduction of cobalt is carried out in electrode region at potential of methylviologen reduction.

In this research, the synthesis of zirconium carbide nano powder at low temperature via carbothermal reduction route was investigated according to thermodynamic data.
Several studies were conducted on carbothermal reduction mechanism of zirconia.
The DTG curve of this sample shows two peaks which is assigned to the carbothermal reduction.
Figure 5 shows the ∆G calculation of the carbothermal reduction of ZrO2.

Then, experiments were conducted to provide basic data on the crack control, strength improvement and spalling prevention of HPC exposed to high temperatures.
Weight reduction ratio Fig. 4 presents weight reduction ratios of HPC specimens according to temperatures.
However, from 250oC to 500oC, it was clear to identify an increase in their weight reduction ratio.
In particular, for the FA-PP-03, its weight reduction ratio was 1.1% at 600oC, showing more significant reduction than that of other specimens.
However, at over 600oC, dehydration of CaCO3 began, increasing the weight reduction ratio.

The high volume of data resulting from these observations presents many challenges, particularly in the areas of data transmission, data storage and assimilation [4].
Suppose our dataset consists of l spectra of n radiances into an l by n data matrix R.
All the channels are completely clear data and none of the eigenvectors correspond to cloud signals.
Performance tests indicate that the WRF 4D-Var minimization requires 21% less computer resources (elapsed CPU time) when 20 PC scores are used instead of 119 AIRS radiance-achieving an 6 fold reduction in data volume and 21% reduction in the overall cost of assimilation.

Synergetic Effects between Al2O3 and HZSM-5 for NO Reduction by CH4 Lili Ren* and Xiaomei Pan School of Chemistry and Chemical Engineering, Southeast University, Nanjing 211189, China *Email: liliren@seu.edu.cn Keywords: Al2O3, HZSM-5, synergetic effect, NOx, selective catalytic reduction Abstract.
Combining with the data of Fig. 1 and Fig. 2, we can conclude that the addition of Al2O3 can improve the selectivity of methane for NO reduction.
In order to promote the reduction NO to N2 by CH4, a certain ratio of NO2/(NO+NO2) must be kept.
But for HZSM-5, it is not only active for NO oxidation, but also active for the reduction of NO2 to NO[10].
Reduction of NO2 to N2 takes place over the proton sites of the zeolite.

Therefore, this paper presents a modified algorithm based on Nesta algorithm to reduce the amount of data sampled of power quality signal, the complexity of the algorithm to improve the algorithm’s speed.
Compressed sensing algorithm is in the process of data sampling is completed while the compression process, then the resulting signal is then compressed in the terminal for data reduction process.
The core content of the compressed sensing algorithm can be seen in three aspects: First, the sparse representation, its main role is the traditional sparse sampling data base by converting a sparse signal in order to remove redundant data signals traditional, with less the amount of data representation signal; Second, the measurement matrix, and its main role is to mapping x N-dimensional signal to the M-dimensional signal y, mainly to ensure that information is not lost; Third reconstruction algorithm, the main role is from M-dimensional signal y matrix through a non-linear projection regain N-dimensional signal.

Experimental data from published literature was adopted to validate the present models.
The experimental data was from Ref. [6].
The NO formation could reasonably agree with the test data when the NO full mechanism was used.
However, if the reburning mechanism was not considered in the simulation, the calculated NO was much more than the experimental data.
The numerical results were a little smaller than experimental data.

From UV-Vis spectroscopy we observe that the absorbance of rGO decreased as increasing the reduction temperature because the higher reduction temperature yields a high degree of rGO defect.
One of the molecules that can be used as reduction agent is hydrazine [12], in which the temperature FOR the reduction takes place is becoming one of the important parameters to obtain reduced graphene oxide with high quality.
By using UV-Vis absorbances data, we could calculate optical constant (refractive index real and imaginary part) of rGO by using a number of Maxwell equation and Kramers-Kronig relation.
Then we have compared the calculation result with other data which have done by other people with other methods.
Increasing the reduction temperature will decrease the CO bonding in rGO plane [15].

The BOSCH BEA-350 exhaust gas analyzer was used to record the data of all exhaust gas emissions.
Test data were generated under full throttle position for different engine speeds (1000, 1500, 2000, 2500, 3000, 3500 and 4000 rpm).
The reason for the reduction of engine power and increase in BSFC are possibly due to slight reduction of cylinder pressure as well as lower heating value of biodiesel.
Impacts of biodiesel combustion on NOx emissions and their reduction approaches.
