Actually, the print-through caused by ink penetration is also due to opacity reduction in the printing area on paper [7-9].
Paper proofing and relevant data testing Because the alleviation of offset print-through could be achieved by properly decreasing printing pressure and increasing printing speed [5], thus 3 sets of printing condition were adapted, which was (625 N, 0.4 m/s), (725 N, 0.3 m/s), (825 N, 0.2 m/s).
In Table 1, data variation among the three factors revealed this law.
Relationships between paper PTR value and print-through property Fig. 2 and Fig. 3 are built up according to the data from Table 1, Table 2.
Also, it is the first time to bring PTR value to predict print-through property for paper print, the prejudging model is built up, and the data show when PTR value is lower than 72%, the print-through problems will be more serious with the falling PTR.

Based on data provided by the NADCA (North American Die Casting Association) formed by die casting thickness of about 3.2mm, filling time between 0.042 to 0.071 seconds [7], and filling time with the formula (1) can be drawn from the gate of the study area, on the design criteria for the location of the gate [8] to find the appropriate location of the gate, the gate area, together with the calculated step to complete the gate design.
Taguchi design: Taguchi method is one of the efficient problems solving tools to upgrade the performance of products and processes with a significant reduction in cost and time involved.
Data from 9 experiments with five sampling times in each simulation are summarized as in Table 4.
Experimental data The parameter design study involves control and noise factors.
Analog measurement data, calculated after sorting out the S / N response table as Table 5 and S / N response graphs in Fig. 6, by the responding graph learned that the best combination for this study with ADC10 aluminum die casting shrinkage defects small is A3B2C1D3.

The applications of PANI as a kind of electrode material for the oxidation of hydrogen [2], methanol [3], ascorbic acid [4], and oxygen reduction [5] were studied by many investigators.
The electropolymerization experiments were carried out in a three-electrode single compartment cell using a potentiostat ( model TD3690) which was coupled to a PC through a data acquisition card for process control and data storage.
The induction period evident seen from the data in Fig. 2, marking the delay period prior to the PANI film formation on lead, was also found to depend on the applied potential.
The relevant kinetic data obtained by analysis of Fig. 4 are presented in table 1.

Mechanical properties at the different study zones Zone 2.0 [MPa] UTS [MPa] Area reduction [%] Deformation [%] Hardness [HRB] BM 271 411 62 35.5 89.8 DM 345 551 - - 92.8 HAZ 277 362 - - 84.4 The final dimensions of the non standard curved SEN specimens were: width 25.4 mm, thickness 25.4 mm. and length 127 mm.
It is clear that the FCG data for this zone did not behave according to Paris' Law, showing great data dispersion, particularly in the zone of low ∆K values.
Figs. 6 and 7 show the FCG rates results for the DM and the HAZ respectively; these data behaved according to Paris' Law.
The weld deposited metal and the heat affected zones behaved according to Paris' law, unlike the base metal, which showed a significant data dispersion in the lower side of the Paris' region.

It has been shown that the driving force for grain growth is the reduction in the grain surface area of the material.
However, when comparing local dynamics the simulation data demonstrates that significant differences may be found, as exemplified for one particular grain in Fig. 4.
Discussion and Conclusion Based on available literature data and the present discussion it seems that the three simulation techniques developed by Weygand et al., Sætre and Ryum and Surface Evolver describe equally well grain growth in a large, idealized system.
However, when studying small grain systems, which is the case when local effects are under investigation, the choice of model may be more critical and one has to be careful when analysing the data.
An interesting aspect of further work would be to find the minimum MC grain system that gives reliable output data, e.g. with respect to kinetics.

Earthquake Detect STA/LTA Method Earthquake emergency auto-handling is an effective method to earthquake prevention and disaster reduction.
The formula using the regression analysis method by the Eq.1 and Eq.2: (1) (2) Where: STA and LTA represent average of short time snatch and longtime window at i moment respectively; CF(i) represents the characteristic function at i moment; Nsta and Nlta represent the data point numbers of short time snatch and longtime window respectively.
The seismic acceleration is scattered data which collects by spectral intensity sensor of earthquake.
In order to improve the instantaneity of arithmetic, use the method of fast data integration to estimate spectral intensity of ground motion.
