英国的3C环境和国内有很大不同。首先,英国用户对电脑的要求喜好和国内不同。以台式机为例.DIY在英国并不是很流行,花心思装配一台电脑是很多人不愿意去做的。他们重视的是享受到什么服务和附加价值.例如一些店铺举行促销的话有时候买电脑还会送一年宽带。因此英国人买电脑都是以买品牌机为主。 相似文献

安装PDFtoJPG 1.2.3汉化版后,即可得到该软件的绿色汉化版。但是用它们转换PDF文件所得到的JPG图片上都会有试用版的水印。用十六进制编辑器WinHex V16.0.5绿色中文特别版打开PDFtoJPG.exe,将水印文字清零即可得到绿色汉化去水印版。然后将需要转换的PDF文件拖放到程序列表区,点击转换就可以得到无水印的JPG图片。 相似文献

An algorithm is presented which provides Air Force schedulers the capabilit alternative schedules rapidly. This capability enhances the schedulers' ability to obtain “good” schedules by: (1) providing for rapid rescheduling in the event of inevitable changeswhich routinely occur during the period of the schedule, (2) presenting a specific quantifiable set of objectives to be met by the schedule.The algorithm is designed specifically for use by B-52 and KC-135 schedulers in the Strategic Air Command. The objective function includes a term for minimizing hours remaining to phase inspections, where hours remaining to phase inspection refers to the number of flying hours an aircraft is permitted to accrue prior to being grounded for the maintenance action referred to as a phase inspection.Another term in the objective function is to maximize the number of turn-around flights, where a turn-around flight occurs when the same aircraft flys more than one sortie in a 48 hr time period. A turn-around sortie requires less pre-flight maintenance and thus results in a cost savings.A very favorable comparison is presented of algorithm schedules with schedules manually prepared in an operational environment. 相似文献

提出了一种在数字印章图像中的圆环上嵌入信息的方法,以实现文档认证的目的。分析了Bresenham圆序列的各种性质,提出了两个具体的圆环信息嵌入算法,分析了它们的嵌入量和平均形变量。第一个算法仅在圆环的外圆中嵌入数据,其形变较小;第二个算法同时在外圆和内圆中嵌入信息,使信息嵌入量增大了一倍。实验与分析表明,两种算法的平均形变量均小于1像素,其嵌入效果也令人满意。此外,两种算法在普通大小的数字印章中可分别嵌入HMAC-SHA512认证码和1 024比特的RSA签名结果。 相似文献

From patterns to frameworks to parallel programs 总被引:1,自引:0,他引:1

Object-oriented programming, design patterns, and frameworks are abstraction techniques that have been used to reduce the complexity of sequential programming. This paper describes our approach of applying these three techniques to the more difficult parallel programming domain. The Parallel Design Patterns (PDP) process, the basis of the CO2P3S parallel programming system, combines these techniques in a layered development model. The result is a new approach to parallel programming that addresses correctness and openness in a unique way. At the topmost development layer, a customized framework is generated from a design pattern specification of the parallel structure of the program. This framework encapsulates all of the structural details of the pattern, including communication and synchronization, to prevent programmer errors and ensure correctness. Lower layers are used only for performance tuning to make the code as efficient as necessary. This paper describes CO2P3S, based on the PDP process, and demonstrates it using an example application. We also provide results from a usability study of CO2P3S. 相似文献
