The validated data were employed to construct the FLD.
Alternatively, the evolution in term of strain rate and strain acceleration can be obtained from the post-processing of ARAMIS data.
The reduction in strain acceleration from maximum to zero represents the process of localization.

The reduction of various types of noise in images has been an active area of research in image processing and machine vision [2-4].
The de-noise method presented in this paper is applied in the data processing.

Results and Discussion Figure 1 shows the set of I-V curves across each of the 4 contacts (A-D) of a Si-face 1cm x 1cm sample measured at 300K (room temperature) along with linear fits to each data set, indicating the ohmic behavior of the Ni contacts.
Figure 2 shows the resistivity versus temperature for two differently doped Si-face substrates (note that the lines in Figs. 2, 3, and 5 are polynomial fits to the data to reveal trends).
The increase in resistivity at low temperature is due to the mobility decrease caused by impurity scattering, and the reduction in free carrier concentration.

The Ti-added IF steel sheets were hot-rolled in five passes from 1050 to 920℃ (finishing deformation temperature: FDT) after holding for 60min at 1200℃ (slab reheating temperature: SRT) and then cold-rolled by 80% reduction.
Tensile tests were carried out for the recrystallized specimens to get data for strength, elongation and plastic anisotropy(ř).
The ř-values of the specimens calculated from XRD data shows also similar tendency (Figure 1).

On the other hand, the sample appears the miscellaneous phase, the lower of purity causes the reduction of crystallization degree.
The XRD patterns of Zn0.98Co0.02O nano powders: (a) for unannealed sample; (b) annealed in air at 600°C The microstructure data that are shown in Table 1 were calculated.
We compare the data to the Table 1 and find that the lattice constant of annealed sample increases and the peak position appears red shift phenomenon.

Chemical shrinkage is the reduction of absolute volume of cement paste in hydration process.
Examples For the sake of verifying the present model, the data of reference [4][5] is applied, and the experimental parameters are listed in table 3.

Due to its unique chemical structure, PFOS is very stable in ambient environments, so it is difficult for conventional methods such as oxidation and reduction to decompose it [7].
As shown in Fig.2, the pseudo-second-order model fitted the experimental data better than the pseudo-first-order model according to the value of (R2), suggesting the sorption of PFOS onto the MIP or NIP is mainly chemical adsorption.
From this experiment, the adsorption reached equilibrium nearly after 3h and the sorption amount of the MIP adsorbents for PFOS reached up to 117.6 mg/g, higher than 74.6 mg/g of the NIP adsorbents, at the same time, pseudo-second-order kinetic model fit the experiment data well.

Rule 3: if target object and the controlled object distance gradually increased and D is between L+△m and L+△n, not unlock signal output strength reduction.
The actual experimental data be shown as in Table 1.

However, the organic coatings may be degraded under various service conditions, and their degradation may result to a reduction of their anti-corrosive effectiveness.
In order to determine corrosion products under the organic coating, XAS data were collected from both blister region and intact area.
Whilst a considerable progress has recently been made in the theoretical treatment of XANES (X-ray Absorption Near-Edge Structure) spectra [15], qualitative treatment, relying on comparing the data from experiments with those obtained from appropriate reference compounds, remains by far the most widely used approach.

Azo compounds can be prepared by the standard diazo-coupling method and by reduction of aromatic nitro-compounds[9,10], but these methods can not be used to synthesize azo aromatic diacyl chlorides.
All the compounds gave satisfactory analytical and spectroscopic data.
