两种解决方案 Richard just finished building his new house. Now the only thing the house misses is a cute little wooden fence. He had no idea how to make a wooden fence, so he decided to order one. Somehow he got his hands on the ACME Fence Catalogue 2002, the ultimate resource on cute little wooden fences. After reading its preface he already knew, what makes a little wooden fence cute. A wooden fence consists of N wooden planks, placed vertically in a row next to each other. A fence looks cute if and only if the following conditions are met: ?The planks have different lengths, namely 1, 2, . . . , N plank length units. ?Each plank with two neighbors is either larger than each of its neighbors or smaller than each of them. (Note that this makes the top of the fence alternately rise and fall.)

利用SyncML开发客户端程序的中间件，J2ME版本。 This library is a collection of basic utilities for: object serialization and persistence on the RMS, Logging and string manipulation. This document describes the Funambol JavaME Common API library, which purpose is giving support and providing basic functionalities to all the other components developed for the J2ME platform. These functionalities are: a persistent data storage framework, a logging framework, a framework to read different streams of byte, a thread monitoring system and a set of classes useful for data encoding and string manipulation. This library may grow in future, as new functions will be seen as common to different J2ME components.

Foundations of Python Network Programming leads readers through every aspect of client and server programming with Python. Python is a new and innovative scripting language. It is set to replace Perl as the programming language of choice for scripters and for serious application developers wanting a feature rich yet simple language to deploy their products in. This book features extensive examples that not only demonstrate important concepts and practices, but also provide a cadre of fully-functional stand-alone programs. Readers can use the examples as the basis and building blocks for their own software

身份认证和数字签名在实际应用中是通过以数字证书为核心的公开密钥基础结构(PKI)来实现的，PKI是实施安全认证方面的国际标准。SSL和SET是现在国际上比较流行的PKI安全协议，但它们也有设计上的缺陷和不适合中国国情的地方。本文详细分析了SSL协议，提出增加SSL签名协议来弥补SSL在数字签名方面的不足，本文详细地设计了SSL签名协议的模型，功能和消息格式，并描述了作者用Java技术实现SSL签名协议的JSPE软件包。

根据有无固定基础设施，无线局域网又可分为BSS (Basic Service Set)和IBSS (Independent Basic Service Set)。我们要研究的ad hoc网络属于后者。假设在一个ad hoc网络中，移动节点的发射功率PTx总是恒定的。要发送数据的移动节点总是先监听信道，测量接收到的信号功率X，其中X= I + N, I为接收到的干扰，N是噪声。移动节点只有在X＜INThre时，才可以发射。式中，INThre为背景噪声门限。 在仿真中，我们规定每个移动节点的发射功率是常数，PTx = 1W；接收节点接收机的灵敏度Smin = -80 dBm；信号质量 min = 2 dB；系统的背景噪声门限INThre = 1.2e-10。

This source code has been tested under OpenWindows 2.0, Sun s X11/NeWS server. For Xlib programs that use KeyPress events you should either (1) set the FocusLenience resource to `True , or (2) specifically notify the window manager that you want to receive KeyPress/KeyRelease events (but only in programs that need these events).
