From the point of view of "green chemistry", the relevance and prospects of the electrooxidation of organic compounds is confirmed by numerous scientific data on the practical use of methods developed and introduced into production for obtaining demanded chemical and pharmaceutical preparations.
Electroorganic synthesis is recognized as an environmentally acceptable methodology for the oxidation and / or reduction [33] of organic compounds, since hazardous and toxic redox reagents have been replaced by electric current [6].
The proposed mechanisms of the oxidation reaction with oxoammonium salts and the data of quantum chemical calculations and electrochemical measurements on the catalytic effect of pyridine-type bases are described in [38, 39].

Intelligent video surveillance uses fastest and optimized way to alert and provide useful information that makes it more effective to help security personnel to deal with the crisis and to maximize the reduction of false report and omission.
In this manner, the system only needs to build K number of SVMs; each SVM distinguishes one class of data with the data in the remaining K-1 classes.
Since the RBF kernel projects samples nonlinearly to the high-dimensional space, it can solve the problem in such a way that category label and data are non-linear, while the linear kernel can only achieve linear mapping.
Combine these extracted characteristic values to a characteristic vector including characteristic values (due to different characteristics are selected for different scenarios, the value of varies in different circumstances), the characteristic vector F is used to characterize various traffic target pattern categories; c) Use the characteristic vector F of the collected samples as input data, and attach category labels to each sample data, construct sample space of the target recognition ,; d) Feed the training data in the sample space into multi-mode classifiers to train SVM1, SVM2, and SVM3.
When training SVM1, use = 1 sample data as a positive sample, =2, 3, 4 sample data as negative sample; when training SVM2, use = 4 sample data as positive sample, = 2, 3 sample data as negative sample; when training SVM3, use sample data = 2 as positive sample, = 3 sample data as negative sample.

Numerical results of the temperature distribution at different process instants are presented and analyzed, and temperature data at the center of the product throughout time were compared to experimental data reported in the literature and a good agreement was obtained.
One data acquisition system LabVIEW 8.2 was linked to the thermocouples that are located in the pulp center;thus, temperature could be recorded along the process.
The following data were used in the simulations.
Figure 7 illustrates the comparison between the numerical and experimental data of the temperature in the center of the product.
These results are in agreement with the experimental data determined by Leblanc et al. [17].

The project results will comprise an experimental data base, improved slow and fast computational tools as well as design guidelines.
After the manufacturing process the preparation of the teststructure up to the test plays an important role to ensure reliable and high quality experimental data.
Advanced measurement systems In stability tests, but also in testing in general, it is necessary to gain before, during and after testing as many data as possible.
The load-shortening data was stored after every 100 th cycle.
Because failure in the skin-stringer interface was expected during cycling just beyond the onset of global buckling, data was measured more often.

In this frame, no reasonable data can be obtained for the atomic contribution in order to explain such a large anisotropy drop.
The dependence of the anisotropy on substitution is indeed not linear and, for reduced Mn content) equation (2) does not reproduce the experimental data.
The indirect techniques allow the calculation of both isothermal ∆Sm and ∆Tad if heat capacity data (under magnetic field) are available, however, due to the extensive processing of experimental data, a cautious error analysis should be performed to get reliable results [59].
A high MCE could be expected in this alloy due to the large Mn magnetic moment (3.4 µB, if deduced from RT magnetization data in the stoichiometric Ni2MnGa alloy [51]) and the rapid variation of the magnetization around the first-order magnetic transition.
The obtained value for x= 0.19, ∆T≈ 1.62±0.2 K (with ∆H= 2 T, corresponding thus to dTcrit/µ0dH≈ 0.8 K/T), is in good agreement with that obtained starting from pure magnetization data on the same sample in field range 0-2 T, that is, ∆T≈ 1.60±0.5 K.

Data output shows 2010ST exhibited sufficient resistance to general corrosion (0.28 mm/y and 1.01 mm/y) at low concentrations of H2SO4 solution (1M and 2 M H2SO4) whose values correlates to polarization resistance of 42.47 Ω and 19.74 Ω.

However, increase in H2SO4 concentration to 3 M caused a cathodic shift in potential value to -0.178 V due to increase in H2 evolution and O2 reduction reactions.

Chen et al.[6] have proven with the related data in a case study that the promotion of separated collection could contribute to the development of low-carbon economy and circular economy in China.
Annual cost-benefit of waste separated collection mainly includes the following three parts: The sale and utilization of recyclable waste (e.g. composting) and other income, Savings in transport and handling costs because of waste reduction, and more input costs than mixed collection on separated collection and transportation (most for separated waste containers and transport vehicles) and the follow-up manual sorting.

Due to particles sizes reduction the following fragmentation discontinues.
So, we emphasize that the mechanisms of the sizes reduction and stabilization of metallic NP ablated in the liquid is based on the effect of local plasmon resonance which is the main factor of self-organization.

Although more advanced solvents are currently available for CO2 capture and even more advanced technologies are expected to be available in the future, Shell Global Solutions show that no more than a 25% reduction of overall costs of CO2 capture will be offered compared to a conventional 30 wt% MEA solvent so that the CO2 capture costs will continue to be 3~4 times higher than the current carbon trading values[2].
Although many demonstration projects including one in Jinlin oilfield of China have been succeeded a study in 2008 found that the United States will need to drill over 100,000~300,000 injection wells to inject enough carbon dioxide and keep total emissions at 2005 levels based on data from CO2-EOR (enhanced oil recovery) but only ~40,000 oil and gas wells are drilled each year in the U.S.
(2) The storage of CO2 by EOR or reservation underground or seabed would be a small part of all the captured CO2 so that the reduction and recycling of CO2 are more important than the capturing
