为解决LED芯片检测与分选中的漏扫、匹配错误等关键问题,提出自适应变步长扫描方法。该方法对当前局域分布特性进行分析,利用晶圆片局部形变的连续性与保持性对邻近区域芯片分布进行预测,实施步长调整。在检测端,提出基于8邻域位置模型的区域芯片分布特征表征与描述方法,确立自适应步长调整策略,建立物理地址映射视图以及归一化逻辑视图。在分选端,利用已知物理地址映射图和归一化逻辑视图,对扫描区域、步长与路径进行规划,在遍历芯片的同时,实现芯片匹配。实测表明,相比冗余方法,该方法能够以低于4%的冗余率,实现漏扫率低于0.5%,提升扫描效率近23%。由于只针对有意义的芯片进行查找,可实现接近100%的匹配率,显著改善了算法效率和抗干扰能力。

Application of Multi-agent Particle Swarm Algorithm in Distribution Network Reconfiguration

引用

Chinese Journal of Electronics 2016年第6期25卷 1179-1185页

作者： SHU Dasong huang zhixiong LI Junye ZOU Xiaoyang Central South University Hunan Radio and TV University

An improved algorithm based on Multiagent particle swarm(MAS) is proposed to solve the distribution network reconfiguration problem in this *** approach is a combination of the learning, competition and cooperation mechanism of multi-agent technology and the strategies of Particle swarm optimization(PSO) algorithm. Using the Von Neumann topology structure in PSO algorithm, each particle represents an agent; each agent not only competes and cooperates with its neighborhood,but also absorbs the evolutionary mechanism of PSO algorithm, so as to share the information with the agent of global optimal. The rules of particle renovating reduce unfeasible solution in the process of particle renovating,and it is able to converge to global optimal accurately and quickly. Test on the IEEE 16-node, 32-node and 69-node system shows both a rapid convergence and a good robustness of this proposed approach.

The （Bi0.9Ho0.1）3.999Ti2.997V0.003012 （BHTV） films have been prepared on Pt/Ti/SiO2/Si substrates by solgel method. The microstructure and ferroelectric properties of the BHTV films were investigated. The BHTV films show a single phase of Bi-layered Aurivillius structure and dense microstructure. The Ho3＋/V5＋ cosubstitution can effectively improve the ferroelectric properties. The BHTV film exhibits good ferroelectric properties with 2Pr of 47.6℃/cm2, 2Ec of 265 kV/cm （at applied field of 420 kV/cm）, dielectric constant of 305, dielectric loss of 0.031 （at 1 MHz）, good insulting behavior, as well as the fatigue-free behavior.

Journal of Wuhan University of Technology(Materials Science) 2012年第1期27卷 88-91页

作者： huang Ling MAO Wei huang zhixiong SHI Minxian MEI Qinlin School of Materials Science and Engineering Wuhan University of TechnologyWuhan 430070China

The PZT thin films were prepared on （111）- Pt/Ti/SiO2/Si substrates by sol-gel method, and lead acetate [Pb（CH3COO）2], zirconium nitrate [Zr（NO3）4] were used as raw materials. The X-ray diffractometer （XRD） and scanning electron microscopy （SEM） were used to characterize the phase structure and surface morphology of the films annealed at 650 ~C but with different holding time. Ferroelectric and dielectric properties of the films were measured by the ferroelectric tester and the precision impedance analyzer, respectively. The PZT thin films were constructed with epoxy resin as a composite structure, and the damping properties of the composite were tested by dynamic mechanical analyzer （DMA）. The results show that the films annealed for 90 minutes present a dense and compact crystal arrangement on the surface; moreover, the films also achieve their best electric quality. At the same time, the largest damping loss factor of the composite constructed with the 90 mins-annealed film shows peak value of 0.9, hi^her than the pure epoxy resin.
