	Structure buckling load interval analysis of supercavitating projectile (EI CONFERENCE) 会议论文 OAI收割 2011 9th International Conference on Reliability, Maintainability and Safety: Safety First, Reliability Primary, ICRMS'2011, June 12, 2011 - June 15, 2011, Guiyang, China 作者: Zhou L. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 As a result of supercavitating projectiles with high underwater velocity their structures undergo high longitudinal force. It is necessary to perform structure buckling load interval analysis because the uncertainty of structural own parameters should be considered. Critical buckling load of supercavitating projectiles is calculated by Galerkin method. The partial matrixes of critical buckling load implicit function to each uncertainty variable are deduced and the interval of structure critical buckling load is calculated by interval analysis and convex model methods. Numerical results show that the nominal value lower and upper bounds of critical buckling load increase with the increment of the ratio of base diameter to cavitator diameter. And the uncertainty degree of basic variables should be controlled as far as possible in the project for high reliability. 2011 IEEE.
	Application of quantitative fault tree analysis based on fuzzy synthetic evaluation to software development for space camera (EI CONFERENCE) 会议论文 OAI收割 2011 2nd International Conference on Artificial Intelligence, Management Science and Electronic Commerce, AIMSEC 2011, August 8, 2011 - August 10, 2011, Zhengzhou, China 作者: Li Y.; Li Y.; Li Y.; Li Y. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 Software reliability analysis is a significant measure to guide design of software reliability. Now software fault tree method to carry on software reliability analysis is used more and more. But it can only qualitative carry on the analysis because of many reasons. For example the scale of software is enlarging the software architecture is getting more and more complex the reason of software fault is very difficult to analyze the software is difference with hardware and it is very hard to obtain the expiration the quantitative data and so on. The space camera is extremely high to the reliable request. So the qualitative analysis is unable to satisfy the analysis request. In view of space camera characteristics a method of fault tree analysis based on fuzzy synthetic evaluation is proposed. The results show that the new method makes software quantitative fault tree analysis possible and optimizes. It can also solve the problem of software component which is unable to quantize precisely. 2011 IEEE.
	The registration of aerial infrared and visible images (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Educational and Information Technology, ICEIT 2010, September 17, 2010 - September 19, 2010, Chongqing, China 作者: Liu J.; Wang Y.; Wang Y.; Wang Y.; Wang Y. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 In order to solve the registration problem of different source image existed on aerial image fusion algorithms based on Particle Swarm Optimization (PSO) are applied as search strategy in this paper and Alignment Metric (AM) is used as judgment. This study has realized the different source image registration of infrared and visible light with high speed high accuracy and high reliability. Basically with little restriction of gray level properties a new alignment measure is applied which can efficiently measure the image registration extent and tolerate noise well. Even more the intelligent optimization algorithm - Particle Swarm Optimization (PSO) is combined to improve the registration precision and rate of infrared and visible light. Experimental results indicate that the study attains the registration accuracy of pixel level and every registration time is cut down over 40 percent compared to traditional method. The match algorithm based on AM solves the registration problem that greater differences between different source images are existed on gray and characteristic. At the same time the adoption of combining the intelligent optimization algorithms significantly improves the searching efficiency and convergence speed of the algorithms and the registration result has higher accuracy and stability which builds up solid foundation for different source image fusion. The method in this paper has a magnificent effect and is easy for application and very suitable for engineering use. 2010 IEEE.
	Heterogeneous architecture-based software reliability estimation: Case study (EI CONFERENCE) 会议论文 OAI收割 3rd International Conference on Convergence and Hybrid Information Technology, ICCIT 2008, November 11, 2008 - November 13, 2008, Busan, Korea, Republic of Wei Y.; Shen X.-H. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 With growing system complication multiple structures are constructed in software instead of single architecture style. As a result the traditional architecture-based models that have considered only homogeneous software behaviors are not suitable to the complex system. In this paper a heterogeneous architecture-based model is presented. In order to verify the practicability we apply the model to estimate the system reliability of the astronautics payload communication and monitoring system (APCMS). Multiple structures are constructed in the system i.e. sequence parallel and fault-tolerance. The study results demonstrate that the model is accurate when compared to the actual reliability. Theoretical research must be applied on actual systems to understand their applicability and accuracy. 2008 IEEE.
	A new driving method for LCoS with frame buffer pixels (EI CONFERENCE) 会议论文 OAI收割 ICO20: Display Devices and Systems, August 21, 2005 - August 26, 2005, Changchun, China Song Y.; Ling Z. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 A new driving method for LCoS microdisplays with frame buffer pixels was developed here. The power dissipation of the LCoS microdisplays with frame buffer pixels is higher than that of the LCoS with DRAM-like pixels due to the twice samplings in LCoS with frame buffer pixels. In this paper an adiabatic charging method was used to the second sampling of the frame buffer pixels in order to reduce the power dissipated in the transistors. The power dissipation of the second sampling was calculated when the power sources of the step the ramp and the stair-step are used respectively. The conventional design adopted the step and contributed to high power and so result in more heat to deteriorate the device performance. The power dissipated in the transistors is almost zero if the ideal ramp source is used. The ramp can be the stair-step whose steps are infinity. The stair-step substitutes for the ramp due to easily generation and higher energy efficiency than the step. It can decrease the power dissipation of the LCoS panel and contributes to the heat reduction caused by power dissipation which can increase the microdisplay devices reliability. This method was developed based on the frame buffer pixel circuits which we proposed previously and can be applied to the others.
	Low power frame buffer pixel circuits for LCoS microdisplays (EI CONFERENCE) 会议论文 OAI收割 13th International Display Workshops, IDW '06, December 6, 2006 - December 6, 2006, Otsu, Japan Song Y.; Ling Z. 收藏 \| 浏览/下载：16/0 \| 提交时间：2013/03/25 In the frame buffer pixel circuits extra power was dissipated to implement the data transfer operation. Extra power dissipation can not only increase power but also decrease the device reliability. One method to deal with it at pixel level is needed. In this novel pixel circuit one PMOS transistor acts as a simple analog comparator in order to determine whether the discharging by comparing the current pixel voltage and the next frame data voltage.
	Self Imaging technique for refocusing an aerospace camera (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China 作者: Li W.; Li W.; Wang X.; Wang X.; Wang X. 收藏 \| 浏览/下载：34/0 \| 提交时间：2013/03/25 A novel auto-focusing technique using a self imaging approach is developed for an aerospace camera having large aperture and long focus. Its optical system consists of an emitting system receiving system and two penta-prisms. Emitting system has three parts: a light source beamsplitter and aim slit. The receiving system includes a field lens two separate lenses and CCD. Using two little penta-prisms instead of a large planar mirror makes the autofocus system simple and compact. CCD was used as photoelectric converting device. A defocused signal is acquired by measuring the change of the two slit self-images position imaged on the CCD. A simple and compact construction of the auto-focusing system was proposed. The algorithm to calculate the moving of the slit-self images position was analyzed in order to achieve subpixel position estimation. The results of the experiments show a 10m focusing precision. The system demonstrates high resolution easy adjustment and high reliability.
