DLS data show that Ag-SiO2 particles have average diameters of around 223.4 nm.
In terms of experimental apparatus for data acquisition, the Open Circuit Potential (OCP) is one of the simplest techniques used to monitor corrosion.
Experimental data were acquired and processed by Nova 1.7 software.
Smaller capacitances values obtained after 16h and 24h exposure may indicate that the product of corrosion is obstructing the pores of the organic film, a process that would increase the polarization resistance of the coating and delay the permeation of the electrolyte, causing a reduction in capacitance values.

Recycling via mechanical shredding, microwave pyrolysis and subcritical solvolysis is compared and comprehensive primary data on energy demand and process throughput are examined.
To decide which solution is most efficient, economic and ecological data are plotted on an eco-efficiency portfolio.
Finally, data are plotted on an eco-efficiency portfolio for visualization.
Scenario II and III are characterized by certain estimates and assumptions based on economic and ecological data.
The gathering of extensive primary ecological and economic data enables the identification of further resource efficiency potentials through the entire life cycle.

, (1) If n = 5, substitute the data into the formula to calculate the average power consumption.
The calculation results are shown in Table 3 after the data are substituted into the formula.
The research on carbon emission from lithium battery recycling stage is made on basis of the greenhouse gas emission data in various stages of life cycle as simulated and estimated under Ecoinvent and SimaPro database.
Table 6 Comparison of comprehensive energy consumption and carbon emission of five electric vehicles Code i/Model Coal consumption per 00km mi(kg) Carbon dioxide emission per 100km Qi(kg) 1/ BMW i3 6.553 17.3 2/ Nissan Leaf 7.593 19.938 3/ Mini E 8.674 22.806 4/ Roewe 350 EV 6.074 15.949 5/ BYD E6 11.934 31.288 Substitute the above data into the average comprehensive energy consumption formula: QavgEV is a mean of comprehensive carbon dioxide emission per 100 km; mavg is a mean of comprehensive coal consumption per 100 km
In addition, it is shown from the data of battery production stage: battery weight is directly proportional to battery energy consumption and carbon emission.

By using the software-defined networking architecture, the control plane is separated from the data- forwarding plane.
It affects the primary objective of setting up a network – fast and reliable communication of data.
By using the software-defined networking architecture, the control plane is separated from the data-forwarding plane.
It affects the primary objective of setting up a network – fast and reliable communication of data.
This depends on the device-controller latency in a smart grid and hence it plays a vital role in delivering data packets quickly.

Normative basis for data management. 4.
Application server running the data load is heavy.
Because the data exchanged between a server and a significant reduction in the browser, we can see the results faster application response.
Data backup is the function of user data in the event of damage after using the backup information can be corrupted data recovery, in order to protect the security of user data.
When the data transmission RAID5 disk is damaged, using the remaining data and parity information corresponding to recover corrupted data.

The 3D-profilograf software registers measurements and carries out their statistical processing getting the various data about the investigated sample surface (the area of hollows, the area of raises, the maximum height, the maximum depth etc.).
The experimental data show that it is possible to reproduce the greatest colour coverage on the material of the following sorts: Zeta (hammer) and Zeta (flax) (Tab.2).
Due to the received data the investigated materials can be ranged according to the roughness surface layer indicator as follows: Zeta (flax) Due to the received data the investigated materials can be ranged according to the integrated indicator of the colour coverage estimation as follows: Zeta (flax)> Zeta (a hammer)> VHI> Katlin> Luxpack. 3) Microgeometry influence of the paper surface on the colour rendering is established.
In a case when the roughness indicator Ra is commensurable with the size of a reproduced dot the reduction of printing system colour coverage is observed.

Daily data came from Da-dong-yong, a typical provincial hydrological station, seated in Najian County of Dali Prefecture.
Results and discussion An analysis of the equal environments assumption should be made, we only considered the data from Da-dong-yong.
The variation of rainfall showed the regular of seasonal variation, we consolidated data seasonally from 2001 to 2010 and drew a line chart (in Fig.2).
By processing data in 2001-2010, runoff was different during four seasons.

Then according to the data, the relative strategy is invoked.
Regarding ARMA(p, q) as AR(p+q), after pre-treatment of data in accordance with reality, calculating the parameters φ1, φ2, ..., φp+q of AR(p+q).
According to the predictive data by ARMA, e.g. traffic flow, the number of fans that should be open is decided [9].
Through the prediction of tunnel traffic flow, it is convenient to establish database of tunnel traffic flow which provides an effective data source for optimizing the ARMA algorithm model, meanwhile, through the ventilation of fuzzy control, the ventilation of tunnel be able to achieve peak condition with the minimum cost.
