With the increase of gray scale and flat panel display (FPD) size, subspace bitwise scanning strategy can be replaced traditional
scanning method to cut down frame frequency. However, the direct searching strategy (DSS) becomes unfeasible to obtain corresponding
high gray scale scanning matrix. Thus, particle swarm optimization (PSO) is introduced to accelerate searching for high gray
scale weights scanning matrix (WSM) with its parallelism and global optimization feature. Finally a WSM of 256 gray scales
is found out successfully with Matlab, which both gray linearity and scanning efficiency are satisfied. 相似文献

This paper discusses a kind of optimal method used for searching flat panel display (FPD) scanning matrix. The method adopts
bionic algorithm: genetic algorithm (GA) and particle swarm optimization (PSO) algorithm. The method using single GA is more
time-consuming, and the search efficiency is low in later evolution; the PSO algorithm is easily falling into the local optimal
solution and appears the premature convergent phenomenon. Hence, a hybrid approach of GAPSO is found to optimize the search
for high grayscale weights scanning matrix. Finally in the acceptable time, it finds a weight scanning matrix (WSM) of 256
gray scales with Matlab, whose scanning efficiency reaches 94.73% and the linearity is very good. 相似文献

改革开放在不断地深化,市场经济在不断地发展,高校为了适应这一新的形势,近几年来已作出了较大的改革举动,而实施完全学分制是其中的一大改革。学分制的实行确实给高校带来了生气,但同时也产生了一系列的负作用,如班级观念的淡化,管理工作的不便。而如何加强学风建设一直是我们所关注的热点问题之一,并不断地进行着探索。经过两年多的实践和总结,我们认识到要抓好学风建设,学院首先要有一个确定的目标,即“争创一流学院,培养一流人才”,并结合学院自身的特点,以狠抓学风建设,全面提高学生素质,加强党建工作为突破口。在上海大学实行全面学分 相似文献
