Optimization with Isight and Ls-dyna  the traditional rigid spring-buffer model whose object is to reduce the impact of acceleration that can not accurately describe the elastic force of the part of the actual situation  the protected component's dynamic stress down about 69.3% and the data recorder's quality 300g lower  finally passed the Marshall Hammer test successfully. 2011 Trans Tech Publications.   Wavelet-based contourlet coding using SPECK algorithm (EI CONFERENCE) 会议论文  OAI收割 2008 9th International Conference on Signal Processing, ICSP 2008, October 26, 2008 - October 29, 2008, Beijing, China Xiu-Wei T.; Xi-Feng Z.; Tie-Fu D. 收藏  |  浏览/下载：55/0  |  提交时间：2013/03/25 We proposed a new still image compression algorithm called CSPECK witch was constructed by the wavelet-based contourlet transform (WBCT) and set partitioning embedded block coding (SPECK). In the WBCT  the high frequency sub-band decomposed by the wavelet transform was further decomposed into multiple directional sub-bands by directional filter bank so as to explain the edge and texture of the image more sparsely. The SPECK algorithm exhibits lower complexity and more efficient compression ratio than SPIHT based on WBCT. Experimental results demonstrate that the proposed method is efficient in coding images that possess mostly textures and contours. The simulation results also show that this new coding algorithm increases the PSNR over CSPIHT. 2008 IEEE.   Temperature-enhanced ultraviolet emission in ZnO thin film (EI CONFERENCE) 会议论文  OAI收割 Zhang Y. J.; Xu C. S.; Liu Y. C.; Liu Y. X.; Wang G. R.; Fan X. W. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 We have studied the structural and optical properties of ZnO thin films prepared by thermal oxidation of ZnS films deposited by plasma assisted electron-beam evaporation on Si(1 0 0) substrates. The transformation from zinc blende ZnS to hexagonal wurtzite ZnO is confirmed by Raman and X-ray diffraction (XRD) measurement. For the sample thermally oxidized at 600 C for 2 h  a novel UV emission peak Ix located at 3.22 eV (385 nm) has been observed. The temperature-dependent photoluminescence spectra show that the integrated intensity of Ix increases exponentially with increasing temperatures within the measuring temperature range  from 80 to 300 K  but the peak position remains nearly constant. We explain this behavior in terms of electron tunneling into the radiative recombination centers.   EFFECTS OF STRENGTH AND COMPRESSIBILITY OF MATERIALS ON WAVE FORMATION AT INTERFACE IN EXPLOSIVE WELDING 会议论文  OAI收割 郑哲敏文集, 2004-06-30 作者:  Li GH(李国豪);  Zheng ZM(郑哲敏) 收藏  |  浏览/下载：27/0  |  提交时间：2015/09/10 WAVE  satisfactory  explosive  explain  welding  stainless  sheets  elasto  郑哲敏  Karman   Asymmetrical Interactions of Positrons With D.
