	Application of particulate reinforced aluminum matrix composite in airborne photoelectric turret (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Electric Information and Control Engineering, ICEICE 2011, April 15, 2011 - April 17, 2011, Wuhan, China 作者: Wang P. 收藏 \| 浏览/下载：25/0 \| 提交时间：2013/03/25 In order to design and manufacture more excellent airborne photoelectric stable turret modulus of elasticity of 213 GPa and thermal expansion coefficient of 7.9106/K. The frame has decreased the maximum deformation by by 60% and increased the fundamental frequency by 65% as compared with those of aluminum alloy materials a new type of aeronautical material-particulate reinforced aluminum matrix composite (SiC/Al composite) is investigated. Several crucial technologies respectively as shown by finite element analysis results. Those are confirmed by vibration test furthermore. Therefore such as pressureless infiltration technology a significant lightening effect is achieved and the thermal control load is also reduced. The test result indicates that the stable accuracy of the system achieves 19.8rad and the optical-axis parallelism of pay load is 0.1mrad. The research applies the SiC/Al composites to airborne photoelectric platforms interface reaction controls and plate's welding are systematically studied. Then which makes a effective exploration for the new aeronautical material's application. 2011 IEEE. using SiC/Al composites the airborne photoelectric stable turret frame is successfully prepared in density of 2.94 g/ cm3

	A dynamic data mining model for engineering management (EI CONFERENCE) 会议论文 OAI收割 2009 Second ISECS International Colloquium on Computing, Communication, Control, and Management, CCCM 2009, August 8, 2009 - August 9, 2009, Sanya, China Zhu J.-W.; Tang Y.-G. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 Data mining has become increasingly critical for the success of companies in this emerging era of Engineering Management. As Engineering Management activities increasingly shift to the web the challenge facing corporate management is maintaining competitive advantage by building strong relations with employees customers and suppliers and partners. A good data mining strategy can help achieve this goal. Unfortunately many companies use data mining technologies that do not suit today's new information era. This paper addresses the definitions about data mining area of data mining development of data mining then provide an summary of the driving and impeding forces that help and hinder proper deployment of data mining strategies in Engineering Management. Finally the paper advocates the strategy of data mining for Engineering Management. 2009 IEEE.
	Photonic micro and sub-micro structures in LiNbO3 crystals (EI CONFERENCE) 会议论文 OAI收割 ICO20: Materials and Nanostructures, August 21, 2005 - August 26, 2005, Changchun, China 作者: Wang P. 收藏 \| 浏览/下载：20/0 \| 提交时间：2013/03/25 High energy lasers processing of materials is knowing an increasing interest since it not only can make manufacturing faster cleaner and more accurate but also because it opens up entirely new technologies and manufacturing methods that are simply not available by using standard techniques. In this paper an experimental set-up based on pulsed KrF excimer Laser assembled for surface patterning of mono and two-dimensional (1D-2D) micro and submicro structures on LiNbO3(LN) crystal will be described in detail. The apparatus has been used to produce photonic structures in LN both by patterning of PMMA photoresist and by direct surface patterning through laser ablation or direct laser writing. The structures and properties of the photonic crystals fabricated by using this apparatus have been investigated and the preliminary results will be presented.
