抓虾-（长篇）明朝的那些事儿－历史应该可以写得好�碵989]
你的朋友"shenjun"（shenjun.pku@gmail.com）从抓虾网（http://www.zhuaxia.com/）给你推荐了一篇文章，内容如下：
（长篇）明朝的那些事儿－历史应该可以写得好看[989]
所谓扶乩，是一种玄乎其玄的玩意儿，大致方法是皇帝把要问的问题写在纸上，然后密封起来，由太监转交给道士，再由道士当众烧毁，权当是转交给神仙，这就算是问完问题了。
那么答案去哪里找呢？你总不能指望天上掉块砖头，上面写着几个大字"我不知道"吧。
正确的程序是这样的，先找来一个沙盘，在沙盘上搭个架子，架子上有两根树枝，分别由两个太监用指头搭住，等到道士把皇帝的问题烧掉，不，是转交神仙，两人便即刻作中风状，两眼紧闭，任由指头在沙上乱画，神仙的答案就是这个了。
可能有人会问，要是画的四不像，那该怎么办，告诉你，不要紧，皇帝大人自然会去琢磨，毕竟我们也不能指望神仙大人的书法水平。
二十多年来，皇帝一直通过这种方式和神仙沟通、交流心得、请教问题，于是疑问又出现了，以嘉靖的性格，怎么能够几十年如一日去研究扶乩中出现的莫名其妙的符号呢？
嘉靖并不是一个有耐心的人，所以答案是，他所看到的并不是鬼画符，而是足以识别的汉字。
其实用指头搭在树枝上，也是可以写出规范回答的，但需要一个条件——故意，只要你没有被鬼上身，只要你还有清醒的意识，你的手腕就能让你写出清晰的汉字，当然这绝不是神仙的意图，而是你自己的答复。
也就是说，嘉靖先生费尽心机得到的所谓神仙热线，不过是出自几个道士太监的手笔，但由于他过于期待上天的信息，所以仍然无怨无悔地相信了它几十年。
其实这也怪不得道士和太监，人家也是迫不得已，你写那些无聊的问题，还不许人看，偏偏还要神仙回信，乱画一气你又看不懂，看不懂就要发脾气，到时自然还是下人们遭殃，道士也好，太监也罢，大家出来混，不过是想混饭吃，何苦难为人呢，就这么忽悠着过吧。
而在这个把戏中，最为关键的人却不是皇帝，而是那个烧掉纸的道士。
因为他是转交皇帝问题的人，也是最为重要的一环，所以这个职位一向由皇帝最宠信的道士担任，比如之前的邵元节，后来的陶仲文，以及现在的蓝道行。
蓝道行人如其名，还真是有点道行，据说他算命看相十分之准，名声很大，便被推举进宫为皇帝服务，并担任那个烧纸的工作。

IGI - Architectural Design of Multi-Agent Systems: Technologies and Techniques
TITLE : Architectural Design of Multi-Agent Systems: Technologies and Techniques (Premier Reference Series) (Hardcover)
AUTHOR : by Hong Lin (Editor)
PUBLISHER : IGI Global publisher
ISBN : 1599041081
EDITION : 1st
PUB DATE : June 05, 2007
LANGUAGE : English
Agent-oriented design has become on of the most active areas in the
field of software engineering. Although great advances have been made in
the study of the architectural design of agent systems, the complexity
and multi-disciplinary approaches of this constantly growing field are
currently of a premature nature compared to where they should be.
Architectural Design of Multi-Agent Systems: Technologies and Techniques
provides a compilation of advanced research results focusing on
architecture and modeling issues of multi-agent systems. This study
serves as a reference for further research on system models,
architectural design languages, formal methods and reasoning, module
interface design, and design issues. Architectural Design of Multi-Agent
Systems: Technologies and Techniques presents high-level issues such as:
modeling agent systems in cognitive sciences, knowledge management,
in-depth exposure of agent theory, and state-of-the-art research on
design quality of agent systems.

抓虾-Self-Similar Processes in Telecommunications
你的朋友"shenjun"（shenjun.pku@gmail.com）从抓虾网（http://www.zhuaxia.com/）给你推荐了一篇文章，内容如下：
Self-Similar Processes in Telecommunications
For the first time the problems of voice services self-similarity are discussed systematically and in detail with specific examples and illustrations.
'Self-Similar Processes in Telecommunications' considers the self-similar (fractal and multifractal) models of telecommunication traffic and efficiency based on the assumption that its traffic has fractal or multifractal properties (is self-similar). The theoretical aspects of the most well-known traffic models demonstrating self-similar properties are discussed in detail and the comparative analysis of the different models' efficiency for self-similar traffic is presented.
This book demonstrates how to use self-similar processes for designing new telecommunications systems and optimizing existing networks so as to achieve maximum efficiency and serviceability. The approach is rooted in theory, describing the algorithms (the logical arithmetical or computational procedures that define how a task is performed) for modeling these self-similar processes. However, the language and ideas are essentially accessible for those who have a general knowledge of the subject area and the advice is highly practical: all models, problems and solutions are illustrated throughout using numerous real-world examples.
Adopts a detailed, theoretical, yet broad-based and practical mathematical approach for designing and operating numerous types of telecommunications systems and networks so as to achieve maximum efficiency
- Places the subject in context, describing the current algorithms that make up the fractal or self-similar processes while pointing to the future development of the technology
- Offers a comparative analysis of the different types of self-similar process usage within the context of local area networks, wide area networks and in the modeling of video traffic and mobile communications networks
- Describes how mathematical models are used as a basis for building numerous types of network, including voice, audio, data, video, multimedia services and IP (Internet Protocol) telephony
The book will appeal to the wide range of specialists dealing with the design and exploitation of telecommunication systems. It will be useful for the post-graduate students, lecturers and researchers connected with communication networks disciplines.
