图片演示稿，PowerPoint快速造

当要在PowerPoint制作图片数很多的图片演示文稿时，如果采用一张张地插入，操作麻烦且易出错，而咱们借助PowerPoint2003中的“相册”功能便可快速完成。     

Flash Lite,动画如我

可爱的动画、搞笑的视频、Flash游戏……不仅在电脑上才可以实现,现在在自己手机上也可以随意观看和玩耍。不过,或许很多人都在纳闷为什么自己的手机无法使用Flash播放视频、网页或者游戏,其实,我们只要为手机装上FlashLite即可（图1）,不管是S60还是Windows Mobile操作系统,安装Flash Lite后就可以在手机上面播放SWF格式的Flash多媒体或游戏（图2、图3）。     

巧在POPO群告中播放视频

一般情况下，IM软件群公告窗口显示的都是一些字内容．不过在POPO的群窗口中．可以存放一些图片件．甚至播放一些多媒体件．如歌曲、视频等。     

给USB端口请个管家

以前公司里面的电脑都是没有软驱的，因为可以防止资料外泄，但是现在新买的电脑都有USB端口，这样给U盘盗取电脑资料提供了方便，怎么办呢？其实我们可以给电脑请一个USB端口管家，让它来帮我们把关。“USB安全存储专家”就是一个这样的软件，它可以让USB端口完全禁用，而且还可以让指定的USB设备来使用端口。     

巧用MPC实现断点续播

有些电影文件做得不够完善，无法拖动滚动条来定位，如一旦停止就得从头看起。如果你使用的是Media Player Classic（MPC）播放器，那么完全可以实现断点续播，并且定位准确。     

手机“无间道” 手机监控和反监控软件推荐

由于手机的使用越来越广泛,许多事情都是通过手机来联系,手机在我们日常生活中也扮演着越来越重要的角色。加上现在手机功能逐渐强大起来,手机软件逐渐增多,我们要怎样好好地利用这些功能和软件呢？比如面对手机盗窃时的资料安全等问题,我们就需要用一些不让资料外泄的软件,攻之有道;而面对电话、短信骚扰时,我们要用一些防止骚扰的软件,防之有道。在攻防之间,保护好自己的手机,也保护好自己的资料。     

让不同用户安装的程序不串门

多人共用的电脑一般都采用建立多用户的方法来解决．这样就可以有自己的桌面及自己的用机环境．但是有些我们自己安装的程序．都会显示在其他用户的开始菜单中．而别人安装的程序也会出现在自己的开始菜单中．这样就导致开始菜单中有很多别人的程序．又不能删除它们。其实我们可以通过组策略来解决这个问题。     

Simulation-based learning of cost-to-go for control of nonlinear processes

In this paper, we present a simulation-based dynamic programming method that learns the ‘cost-to-go’ function in an iterative manner. The method is intended to combat two important drawbacks of the conventional Model Predictive Control (MPC) formulation, which are the potentially exorbitant online computational requirement and the inability to consider the future interplay between uncertainty and estimation in the optimal control calculation. We use a nonlinear Van de Vusse reactor to investigate the efficacy of the proposed approach and identify further research issues. This paper is dedicated to Professor Hyun-Ku Rhee on the occasion of his retirement from Seoul National University.     

Strong magnetoelastic effect in Pr1−xCaxMnO3

Manganese oxides with distorted perovskite structure have attracted much attention during the last decade due to their colossal magnetoresistance (CMR), and the strong correlations among the various degrees of freedom involved. In particular, Pr_1−xCa_xMnO₃ compounds present in a wide Ca-doping range a charge ordering phenomenon, consisting of real space ordering of Mn³⁺ and Mn⁴⁺ in alternate lattice sites below a certain temperature T_CO. This ordering brings about a lattice distortion and a large hardening of the sound velocity below T_CO. Tomioka et al. have observed that an applied magnetic field can melt this charge ordered state and induce a transition from an insulating to a metallic state. In order to study the effects of this charge order melting, ultrasonic longitudinal sound velocity measurements were performed on polycrystalline Pr_1−xCa_xMnO₃ (x=0.35 and 0.5) as a function of magnetic field and temperature. Interesting anomalies were found related to the melting of the charge ordered phase into a metal-like state even at low temperatures.
