摘要： This paper presents a performance analysis of the Identifier Splitting Algorithm combined with polling, a contention resolution scheme used to inform the Base Station about the bandwidth needs of the Mobile Station in a wireless ATM network. An analytical model leads to the evaluation of performance parameters which determine the throughput and the access delay of the algorithm for different system parameters. This analysis is used to investigate the influence of the system parameters on the performance, from which guidelines for parameter tuning can be derived.

摘要： 提出了一种支持信息的私有性和通信方的认证性的基于用户标识符(ID)的安全的认证和密钥分配方案。当安全网络系统建立后,不需要可信第三方参与认证过程,通信双方执行协议后,仅用两个信息就获得双方相互认证和产生共享密钥。

摘要： ＡＯＤＥ是一个基于Ｊａｖａ的Ａｇｅｎｔ应用开发环境，本文给出了其总体框架．ＡＯＤＥ为Ａｇｅｎｔ系统的开发提出了一种方法，并提供了一组开发工具包和一套可扩充的类库实现该方法的各阶段．由于利用ＡＯＤＥ，开发人员只需关注领域级问题求解能力，Ａｇｅｎｔ级功能如通讯、合作和协商等主要由ＡＯＤＥ构件类库实现，从而大大方便Ａｇｅｎｔ应用系统的开发．

摘要： The design and testing of a pi/mu identifier suitable for use in pion-proton elastic scattering experiments in the momentum range 65-160 MeV/c is described. A neural network technique is used for particle identification. The apparatus (a multilayer scintillator stack) was found to have a particle identification efficiency of better than 98%.

摘要： Q DW中如何输入空格?A 按下“Ctrl+Shift+空格键”或者在中文输入法中选择全角输入方式,可任意输入空格。Q 为什么我的Dreamweaver会出现黄色标识符?A 有时我们在Dreamweaver中会发现有黄色的标识符,它们是什么呢?其实这是由你的网页代码中标识符不匹配或非法标识符引起的,解决方法就是去掉非法标识符。Q DW中如何设置页面边距为0?A 可惜,DW中似乎没有直接设置的方法,你只有在HTML文档中插入以下代码:marginheight=“0” marginwidth=“0” topmargin=“0”leftmargin=“0”。Q 为什么我想让一行字居中,但其他行字也变成居中?A 这是我们经常碰到的麻烦事,为什么呢?在Dreamweaver中进行距中、距右操作时,默认的区域是P、H1-H6、DIV等格式标识符,因此如果您的语句没有用上述标识符隔开,Dreamweaver会将整段文字均做距中处理,解决方法就是将距中文本

摘要： The use of tracking technology (electronic identifiers to track digital evidence left behind from the attacks) to apprehend a programmer charged with authoring the Melissa virus; as well as the perpetrators of the Distributed Denial of Service (DDOS) attacks that Yahoo! recently suffered,1 may have created a dangerous precedent for electronic privacy, according to legal experts.2 In the Yahoo! case, hunting down the hackers who launched the denial of serviceattacks against Web sites won't be easy. The attacks paralyzed popular sites like Yahoo!, eBay, Amazon, *** and ***. In the Melissa case, the perpetrator, 30, of Aberdeen, New Jersey, was arrested and arraigned in April, 1999, following a national man- hunt. According to New Jersey Attorney General's office, the perpetrator's arrest was made as a direct result of information provided by America Online, Inc. (AOL) through their use of electronic identifier technology. Let's look at some of this technology.
