The FTIR measurements showed the presence of bioactive compounds in the extract responsible for the efficient reduction of silver ions and stabilization of the AgNPs.
Based on the principle of green chemistry, we investigated a green approach for preparation of AgNPs by the reduction of Ag+ ions to Ag° with bio-reductants in the leaf extract of Piper betle L.
The overall reduction reaction process took place in dark to avoid unnecessary photochemical reactions.
The reduction reaction was almost completed within 4 h because the SPR intensity relatively slightly increased after this time.
Furthermore, the diffraction peaks data of the AgNPs were in accordance with the reports of the face center cubic (FCC) structure [11-13].

The potential errors are analyzed and raw data of the IMU is preprocessed effectively.
The noise in A/D sampling influenced the accuracy of raw data.
The multi-attitude acceleration data is shown in Table.2.
Magnetic data is sampled before calibration and after calibration[9].

In the application process of wireless sensor network, LEACH protocol solves the problem of data fusion well, and reduces data exchanges between nodes and bases.
Based on the research, this paper proposes an advanced LEACH protocol, which is fused by the data of cluster head, and each time when transmits data to the neighbor shortest cluster head, this protocol gets reduction in the aspects of theoretical existing and energy consumption, and improvement in using efficiency.
Compared with the planar routing, the cluster structure through data fusion, can eliminate redundant data, reduce network traffic, effectively save energy, and prolong the network survival time.
The node distribution is very close, and the data collected by the neighboring notes have high similarity, and there are a large amount of redundant information and it requires that each node should have the function of data fusion.

We screen the data which has the typical characteristics of power parameters from test data, and compared with the national power quality standards.
Introduction In response to the global climate and energy problems, all countries in the world attaches great importance to energy conservation and emissions reduction, development of low carbon economy and new energy vehicles industry.
On the one hand to energy conservation and emissions reduction, and improve the energy supply mode, on the other hand is to adjust the industrial structure, improve productivity, enhance the international competitiveness of China’s auto industry.
In this paper, according to the actual on-board charger test, the measured data are obtained, on the basis of these data to make an analysis of its steady-state power quality indicators.
Monitoring equipment including: an oscilloscope is used to record the waveform of voltage and current at input side in real time; a power analyzer to collect U-I-P and other data in the whole charging process.

Comparison of prediction models for time-to-cracking has been done in a recently published study, which indicated simple prediction models provide better good fit to various sets of experimental data than complex models.
As a follow-up, this study uses published crack-width data to compare different models, developed in the literature to predict crack-width of concrete cover.
Although both of the empirical and numerical approaches are attractive for real-life applications owing to their ease of data collection, they have limited explaining for the process of cracking and growth of crack width.
From the data collection point of view, crack width at the surface is easy to measure.
The only difficulty in data collection is the corrosion current density (icorr), which might be assumed for buried concrete structures.

An earlier report on pulse deposited ZnSe films presented data on the ZnSe films deposited at different duty cycles [8].
So it promotes the reduction of the ZnSe films.
The position of Zn2+ adsorption is occupied by other substance (such as H2SeO3), Zn2+ reduction is fewer than HSeO3- reduction, so it advantageously forms Se groups.
So the reduction of selenium would decrease and the reduction of zinc would increase.
Therefore, it promotes the Zn2+ adsorption and the Se reduction, promotes the co-deposition of ZnSe.

Based on literature data and the performance-based approach of “Model Code for Service Life Design” published by the International Federation for Structural Concrete (fib), risks associated with the use of using seawater in relation to the service life a reinforced concrete element in a marine environment are investigated.
During the development of the project, laboratory and field tests will allow for the collection of experimental data to better define the durability evaluation and analyse advantages of the proposed approach in terms of life cycle assessment.
For the types of concrete considered in this work, experimental data on DRCM published in a previous work were considered: DRCM of 6.5∙10-12 m2/s and 4.5∙10-12 m2/s for OPC and FA concretes were assumed, respectively [3].
Thus, the values of Clth for the stainless steel reinforcement were determined through literature data.
As far as XM-28 stainless steel is concerned few data are reported in the literature and a mean value and a standard deviations respectively equal to 3.4 and 0.6% mass of cement was taken into account as suggested in [9].

Results and Discussion All the presented data in this work is obtained by the structural characterization using XRD technique.
The a- and b-axis length seems to be unchanged while the c-axis length decreases due to Ce doping concentration (x) and reduction annealing effect.
Both the Ce-doping and the annealing reduction effect gives a change in the electron density distribution at the O(1) site.
The annealing reduction also gives a change of electron density distribution at around the apical oxygen O(3) as shown in Fig. 3(b).

For estimation of the effective mass diffusion coefficient, experiment data of average moisture content of cassava cubes (fresh and osmotically dehydrated) was fitted to the simplified Fick model and a good agreement was obtained.
The effect of water is related to large waste, reduction in quality, and shelf life of these materials.
The average final moisture content data were subjected to variance analysis at a significance level of 5% and Tukey test means comparison by using STATISTICA® software [17-19].
Experimental drying data were adjusted to the simplified Fick´s model [20] to predict the drying process and to estimate the water effective diffusivity, considering uniform initial moisture distribution, absence of thermal effect in mass transfer, and applied to an infinite flat plate and long drying time.
Osmotic pretreatment resulted in a reduction of free water in these samples, contributing to the reduction of the mass transfer rate in convective drying.

However, sintering behavior is heavily de- pendent on the morphology of the powder particles, since sintering progress is driven by reduction of the bound surface energy.
Morphology data are obtained from microscopic imaging by extracting the 2D contours.
Constrained freedom in movement in contact zones between particles introduces additional stresses which are influencing the generate particle group simulate particle group powder data average sintering behavior generate particle group simulate particle group generate particle group simulate particle group Fig. 2.
Therefore, it was decided to draw all sieve classes together for the description of the parameters o, hp and np to minimize the effort of data collection, since the measurement of one particle took about 10 min.
This offers the possibility to lower experimental effort for data generation.
