兩種解決方案 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開(kāi)發(fā)客戶端程序的中間件，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

根據(jù)有無(wú)固定基礎(chǔ)設(shè)施，無(wú)線局域網(wǎng)又可分為BSS (Basic Service Set)和IBSS (Independent Basic Service Set)。我們要研究的ad hoc網(wǎng)絡(luò)屬于后者。假設(shè)在一個(gè)ad hoc網(wǎng)絡(luò)中，移動(dòng)節(jié)點(diǎn)的發(fā)射功率PTx總是恒定的。要發(fā)送數(shù)據(jù)的移動(dòng)節(jié)點(diǎn)總是先監(jiān)聽(tīng)信道，測(cè)量接收到的信號(hào)功率X，其中X= I + N, I為接收到的干擾，N是噪聲。移動(dòng)節(jié)點(diǎn)只有在X＜INThre時(shí)，才可以發(fā)射。式中，INThre為背景噪聲門(mén)限。 在仿真中，我們規(guī)定每個(gè)移動(dòng)節(jié)點(diǎn)的發(fā)射功率是常數(shù)，PTx = 1W；接收節(jié)點(diǎn)接收機(jī)的靈敏度Smin = -80 dBm；信號(hào)質(zhì)量 min = 2 dB；系統(tǒng)的背景噪聲門(mén)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).
