漫谈视频目标跟踪技术

视频目标跟踪技术是近几年来在计算机视觉领域中兴起的一个新的研究方向。与视觉目标跟踪技术密切相关的应用主要有以下几种类型：（1）智能视频监控系统;（2）基于视觉的人机交互;（3）自动驾驶;（4）虚拟现实。     

重视对经济机制和经济体制的理论研究

为了使十二大所确定的我国经济建设的战略目标、战略重点、战略步骤和一系列方针、政策在实际工作中得到正确的贯彻,促进社会主义经济的全面高涨,必须进一步加强政治经济学的教学,让我们的干部用有关社会主义经济规律的科学知识把自己更好地武装起来。     

给妈妈打工

放长假了,我一天到晚就是吃喝玩乐.妈妈看了直摇头,她对我说:"小跳(因为我爱动),给我打工吧,有工资的!" 我一听,立马来了精神.只见妈妈拿出了一份合同书,上面写着:"假期间,每天上午做一次家务,扫地拖地4元、抹桌子1元、浇花5角、做饭做菜共5元、洗碗3元、洗衣服2元.如工作不到位扣5角,干得好奖励5角."我一看,容易!便挥笔签上大名.

Porous structures of natural materials and bionic design

INTRODUCTION After long period natural selections and evolu-tions,natural porous structures always integrate various functions and have many characters superior to artificial porous structures,which are mainly composed of composite and complex structures.Natural porous structures can prevent seeds,eggs,etc.from invasion of water or cracks due to collision,exchange matters with the environment during the metabolism process,and use less material to form larger space under equivalent conditio…     

考虑越程槽影响的圆柱滚子轮廓设计

In this paper, the effect of the grinding undercut of the raceways on the longitudinal pressure distribution of the profiled rollers, which are the most popular axial profile employed by the bearing manufacturers, was discussed. Based on the profiled roller geometrical equations and numerical calculation of three-dimensional elastic contact problems of finite length, a new numerical method for calculating the crown drop evaluation considering the effect of grinding undercut was used. The analyses of two structure case, that roller length is greater or less than raceway width, were carried out and compared with each other. The Results show that the width of grinding undercut must be considered in determining the crown drop of rollers.
