One challenging topic is the accuracy synthesis which deals with the optimal design of the manufacturing and assembling tolerances of each component under the given pose accuracy. First  the error model of the 3-RPS parallel robot is built based on total derivation of the kinematic equations. And the error variable of each spherical or rotate joint can be expressed as a single boundary error parameter but not three independent position parameters. Then  the accuracy synthesis model is formulated taking the manufacturing costs as the optimization objective and the accuracy requirements as the constraint condition. Finally  the genetic algorithm is used to solve the optimization problem and a simulation example is given. The results show that the accuracy synthesis method based on manufacturing costs can satisfy the need of pose accuracy and is better for engineering application than the method based on error sensitivity. 2012 Chinese Assoc of Automati.   Grayscale control algorithm based on optokinetic nystagmus (EI CONFERENCE) 会议论文 2010 3rd International Conference on Advanced Computer Theory and Engineering, ICACTE 2010, August 20, 2010 - August 22, 2010, Chengdu, China Chen Y.-S.; Gao H.-B.; Su W.-X.; Wang M. 收藏  |  浏览/下载：13/0  |  提交时间：2013/03/25 In order to reduce trailing phenomenon for moving image in FPD (Flat Panel Display)  Then  Finally  grayscale control algorithm is proposed that simulates CRT (Cathode Ray Tube) grayscale rendition process. First  based on algorithm derivation  implemented main program with VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) is presented and specific rendition process is described. Experimental results indicate image quality is evidently improved and proposed algorithm reduces trailing phenomenon nearly 90%  after the reason of trailing phenomenon for moving image is introduced  algorithm realization steps and compared experiment results of traditional and proposed FPD grayscale control algorithm are discussed  when FPD displays moving image  work processes of human eyes are illuminated and grayscale rendition of a pixel is obtained  according with eyes reflection mechanism and programs can correctly implement on circuit board. 2010 IEEE.  when seeing moving image on CRT and FPD
