As discussed above, the data at the loaded area (filled circles) have more ordered structure.
Data points from locations outside the loaded area are associated with the formation of carbon deposits (open circles).
Approaching to the loaded area, the data points moved to the right end of the dashed line (first step of ordering), then, they follow the dashed line (second step of ordering) as indicated by arrows.
Fig. 3 Present data shown in the diagram of G peak width (FWHMG) as a function of the intensity ratio (ID/IG).
Filled circles indicate data from the loaded area and open circles from the outside.

According to HR-TEM images and XRD data rutile crystallites are preferred oriented along the [001] axis.
Results and Discussion According to the XRD data all obtained materials are pure-phase rutile (Fig. 1, Tab. 1).
Particle’s shape anisotropy was took into consideration at XRD data analysis.
This result is consistent with the data about free energy of rutile crystal faces ( E110 < E001 < E011 ) [17].
Adsorption bands caused by hydroxyl groups vibrations are the most significant for S0 sample which correlates to TG data.

Data matrix can be decomposed into two parts as follows
Step1: The sample data would be transformed to the standardize data whose target is the mean value is 0 and the variance equal to 1.
Step2: Using sample data to establish PCA model for the normal state to extract the sample main data.
This sample data set as.

Data hiding in the frequency domain takes advantage of the insensitivity of the HAS to small spectral magnitude changes [2-4].
Quantization index modulation is another type of data hiding algorithms that increases the security of the augmented data at the cost of decreased tolerance to attack noise stronger than the watermark modulation.
The rank r of the factorization is usually chosen such that (n+m)rreduction is achieved.
The experiment results show that: On one hand, in this method, the watermark is registered to third-party website and not embedded into the original data, so there will not influence data precision and therefore keep the quality of original data well.
Zero-watermark extraction of local map would be useful for local data authentication.

An analysis of experimental data using a kinetic model yields the diffusivity of solute in the Cu matrix, which is in agreement with the reported diffusivity of Ni in Cu.
The alloy ingots were homogenized at 900 oC for 24 h in a vacuum and then cold-rolled to 50% reduction in thickness.
A kinetic analysis of experimental data using the growth model by Chen et al. [10] shows that the thickening of g disks is controlled by the Ni diffusion in the Cu matrix.

The photovoltaic data shows that the highest efficiency of 1.41% with a photocurrent density, Jsc of 20.6 mA/cm2, an open-circuit voltage, Voc of 0.32 V and a fill factor, FF of 21.3% were yielded by the sample of CdS(3)/Ag2S(4) as an optimum condition of dipping cycles for CdS and Ag2S under irradiance of 100 mW/cm2 (AM 1.5G).
The characteristics of I-V curves of single CdS(4) and Ag2S(4) as an optimal conditions for each QD materials were shown in Fig. 1(b) and the data are listed in Table 1.
A lower h of 0.70% in Ag2S-loaded electrode is mainly due to the reduction of Voc of 0.35 V.

Distributions of the temperature and heat flux are critical at the edges of the test piece and thermocouples locations, which must be taken into account when comparing test data for coatings with rather different composition and structure.
Conclusions could be made that thermocouples should be chosen from a material with equivalent or lower thermal conductivity than the test head material to avoid excessive heat losses and false data acquisition from the thermocouple, in particularly for low heat fluxes and smaller temperature gradients where errors could be large.
The gradient close to linear might be considered as optimal for the case analysed, providing about 10% reduction of the maximal von Mises stresses and relaxing strong stress gradients as well as stress gradient inversion near the free edge.

The kinetic model tests show that the shrinking core model can be used to correlate with the experimental data.
The maximum reduction in regeneration temperature was achieved for a zinc titanate sorbent with 5wt % Co and 5wt % Ni, which could be regenerated at temperatures as low as 475℃.
According to Siriwardance and Woodruff, the impact of sulfate was ignored in the process of analyzing the kinetic data, because the sorbent regeneration rate is obviously higher than the sulfate generation rate in O2 atmosphere [11].

The analysis of experimental data shows that the coated carbide cutters having high values of helix angle and small values of rake angle, in the negative range, provide the better optimization of highspeed milling of hardened steels.
Improvements in workpiece surface roughness and reduction of cutting forces are other areas of interest in the domain of HSM of hardened steels.
Experiment based research has been carried to study the influence of cutter geometry and cutter coating in HSM of hardened AISI 4340 and AISI D2 using solid carbide end milling cutters and the resulting data have been analyzed.
