MD5算法的ASP实现. 它在MD4的基础上增加了"安全-带子"(Safety-Belts)的概念。虽然MD5比MD4稍微慢一些,但却更为安全。MD5也为一种非常优秀的中间技术。

这本也是经典中的经典。它已经深入到接触 C++ Object Model 的层次。特别是 Exception-Safety 这一章一系列的步步深入,很大 程度上改变了我对 C++ 的认识。此外,它有提到 Pimpl Idiom,这 对改善 C++ 编译效率也有一定的帮助。其他的主题,例如泛型编程 和对标准库的几个讨论议题、暂时物件、物件寿命、自动转换…等,也 颇有深度。如果没看过这本,且对自己的 C++ 功力颇有信心的人,可 以测试看看。

Digital convergence, in recent history, has been prevalentin the consumer equipment domain and the designengineers in this area have been struggling with a plethoraof emerging standards and protocols. What lessons can welearn from their struggle? The same dilemmas now existin in-vehicle telematics and infotainment systems but withthe added issues of extremes of temperature, safety,security, and time in market.

Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and data-acquisition systems. The analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failure, optocoupler failure, or undervoltage condition occurs. A simple application is shown on how to implement thisfunction.

介绍一种基于CAN总线的牵引变电站自动化系统通讯规约的设计,CAN通讯规约采用标准帧,报文采用主动发送和发送查询两种处理形式。该设计在城市轻轨与地铁牵引变电站中的应用表明:可实现间隔层和通讯处理层的数据快速、可靠的交换,提高牵引变电站的安全性和稳定性 。 Abstract: This paper firstly presents a kind of design dealing with communicational protocol to the traction substation automation system based on CAN bus,and then comes up with the ideas that all frames of CAN communicational protocol should adopt the standard frame,and that messages be processed by two ways:sending initiatively and sending quiries.Subway and light rail application shows that the use of the CAN bus is possible to exchange data quickly and reliably between the layers of the middle and the communicational processing,hence to improve the safety and stability of traction substations.
