Analytical formulae for the squeeze film damping coefficient and the squeeze film damping moment on the cantilever beam of the optical switch are derived. Based on the torsion dynamics theory  the technique and relative results are presented for analyzing the actuating voltage and the switch time. The optimized result of parameters is as: length  width and thickness of the torsion beam are 700  12 and 10 m  length and width of the cantilever beam are 1900 and 1000 m  length and width of the balance beam are 100 and 1000 m  shortest spacing between the upper and lower electrodes is 0.05 m  and highness of the lower electrode is 55 m  respectively. The actuating voltage is less than 10 V  and the switching time of Ton and Toff are 1.30ms and 1.25ms  respectively. The computed results show that the air squeeze film damping is an important factor for the study of dynamic response on MOEMS optical switch.   An Analytical Study on Stress Concentration Due to a Cuboid Hole in Structures (CPCI-S收录) 会议论文 MATERIALS ENGINEERING FOR ADVANCED TECHNOLOGIES (ICMEAT 2013) 作者:  Yang, Yi[1];  Cheng, Yufeng[1];  Yang, Chao[1] 收藏  |  浏览/下载：0/0  |  提交时间：2019/04/12 Cuboid hole  Stress concentration  Analytical study  U-transformation   Empirical study on Electronic-Business Capability Conceptual Model: Based on dynamic capabilities view 会议论文 2011 作者:  Liu,Pu;  Wang,Weili;  Cai,Na;  Wang,Yunfeng 收藏  |  浏览/下载：0/0  |  提交时间：2020/01/04 Analytical  models  Information  technology  Investments  Reliability  Organizations  Information  systems  empirical  study  electronic-business  capability  dynamic  capabilities  view   Characterizing the intelligence analysis process: Informing visual analytics design through a longitudinal field study 会议论文 2011 作者:  Stasko,John;  Kang,Youn-ah 收藏  |  浏览/下载：0/0  |  提交时间：2020/01/04 Visual  analytics  Collaboration  Analytical  models  Internet  Information  services  Electronic  publishing  Artificial  intelligence  qualitatvie  user  study  Intelligence  analysis
