Given that the seismic response under Taft wave is similar to that under El Centro wave, the results of Qian’an wave, El Centro wave and Hachinohe wave are presented in Fig. 3.
Under EL Centro wave, the peak shear force response of IRS is basically less than that of NIRS OBE and the shear force ratio of IRS to NIRS equals approximately 1/4.

Gubbels et al. [3] argued that in order to increase production yield it is important to minimize cycle time, decrease production steps and increase the mould tool life.
In another study by Shi et al. [5], they deduced that some materials have proven to be difficult if not impossible to machine with good surface finish using a diamond tool.

Thus the early Gordon and El-Bassyouni findings [2] that, in Al with a few ppm atomic of impurities the most important element affecting grain growth was deduced to be Fe rather than Cu, strongly support the above premise since the solubility of Fe in Al at annealing temperatures of Al alloys is much lower than that of Cu.
Subsequent work on CReX indeed indicated that Fe content of below 1 ppm atomic was required for nominally pure Al [6,7,8] and Al-Mg alloys [9].
This procedure was to getter the Fe solutes as previously shown for Al-Mn [10] and Al-Fe [4, 6] alloys.

For this purpose we coupled the VPSC-model of Lebensohn and Tomé [1] with the hardening model of Peeters et al. [2].
In this work we coupled the hardening model of Peeters et al. [2] with the VPSC-model of Lebensohn and Tomé [1] and implemented it in the commercial finite-element code ABAQUS/ Explicit® [7].
The hardening model The hardening model used in this work was developed by Peeters et al. [2] for the hardening in bcc polycrystals for which it is used also in this work.

One of the ways to improve the electroluminescent (EL) efficiency is the use of a fluorescent-dye dopant[7-9].
The electroluminescent(EL) spectra and Commission Internationale de l’Eclairage(CIE) coordination of these devices were measured by a PR655 spectra scan spectrometer.
Fig.2 is the EL spectral of the devices at 10 V.
