Pegasus is an open-source implementationof the DMTF CIM and WBEM standards. It is designed to be portable and highly modular. It is coded in C++ so that it effectively translates the object concepts of the CIM objects into a programming model but still retains the speed and efficiency of a compiled language. Pegasus is designed to be inherently portable and builds and runs today on most versionsof UNIX(R), Linux, OpenVMS, and Microsoft Windows.

實(shí)驗(yàn)8 繼承與多態(tài) 8.1 實(shí)驗(yàn)?zāi)康? (1) 理解類的繼承，掌握變量隱藏、方法覆蓋的概念。 (2）理解引用類型的變量的賦值轉(zhuǎn)換原則。 (3）理解多態(tài)概念，掌握方法的匹配調(diào)用原則； (4）理解抽象類與接口的使用； (5）理解this和super的含義及使用。 (6）理解訪問控制符的使用 8.2 知識(shí)要點(diǎn) 8.2.1 繼承的概念 通過類的繼承，祖先類的所有成員均將成為子類擁有的“財(cái)富”。但是能否通過子類對(duì)象直接訪問這些成員則取決于訪問權(quán)限設(shè)置。Object類是所有類的祖先。 8.2.2 構(gòu)造方法與繼承關(guān)系 構(gòu)造方法不存在繼承關(guān)系，子類中是如何給父類繼承的屬性賦初值呢？ 子類通過調(diào)用父類的構(gòu)造方法給父類的屬性賦值，在子類的構(gòu)造方法的第1行可以通過super去調(diào)用父類的構(gòu)造方法，如果沒有super調(diào)用，則默認(rèn)調(diào)用父類的無參構(gòu)造方法。所以，在父類中編寫構(gòu)造方法通常均要提供無參構(gòu)造方法。 8.2.3 對(duì)象引用變量賦值原則 可以將子類的對(duì)象引用賦值給父類引用變量，由于父類能操作訪問屬性和方法的子類已全部繼承。但將父類引用變量的值賦給子類引用變量就受到限制，必須進(jìn)行強(qiáng)制轉(zhuǎn)換，編譯總是認(rèn)可強(qiáng)制轉(zhuǎn)換，但運(yùn)行程序時(shí)如果不能正確轉(zhuǎn)換就會(huì)報(bào)錯(cuò)。

Visual tracking is one of the key components for robots to accomplish a given task in a dynamic environment, especially when independently moving objects are included. This paper proposes an extension of Adaptive Visual Servoing (hereafter, AVS) for unknown moving object tracking. The method utilizes binocular stereo vision, but does not need the knowledge of camera parameters. Only one assumption is that the system need stationary references in the both images by which the system can predict the motion of unknown moving objects. The basic ideas how we extended the AVS method such that it can track unknown moving objects are given and formalized into a new AVS system. The experimental results with proposed control architecture are shown and a discussion is given.

This sample displays a basic integer calculator powered by the 8051 microcontroller. Although Keil C51 has a full floating point math library the evaluation version is restricted to 2k of object code, so we have constrained this sample to integer maths in order to fit within this limit. The program for this design was written in C using the Keil uVision 2 IDE for which Proteus VSM provides a Debug Monitor driver. Instructions for configuring Proteus to run in conjunction with the Keil environment can be found by editing the 8051 microcontroller on the schematic (point at it and press CTRL-E) and then clicking on the help button on the Edit Component dialogue form.

For advanced geometry, most apps will prefer to load pre-authored meshes from a file. Fortunately, when using meshes, D3DX does most of the work for this, parsing a geometry file and creating vertx buffers for us. This tutorial shows how to use a D3DXMESH object, including loading it from a file and rendering it. One thing D3DX does not handle for us is the materials and textures for a mesh, so note that we have to handle those manually.

菜單實(shí)現(xiàn)的主要技術(shù)為Javascript, DOM, XML 不會(huì)被任何標(biāo)簽覆蓋，一般的菜單會(huì)被SELECT,OBJECT等標(biāo)簽覆蓋。 可以跨過框架，譬如一個(gè)frameset中有兩個(gè)frame，上一個(gè)frame放菜單，下一個(gè)frame放具體內(nèi)容，那么菜單可以懸浮于下一個(gè)frame之上。 在添加菜單數(shù)據(jù)時(shí)，通過指定父子菜單的ID來達(dá)到動(dòng)態(tài)菜單的目的。 可使用XML存儲(chǔ)菜單數(shù)據(jù)，一般用作靜態(tài)菜單。 使用window.createPopup顯示菜單，所以只能在IE中使用。

The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control and data transfer communication between ICs. Some of the features of the I2C bus are: • Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A 12V supply line (500mA max.) for powering the peripherals often may be present. • Each device connected to the bus is software addressable by a unique address and simple master/ slave relationships exist at all times masters can operate as master-transmitters or as master-receivers. • The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data corruption if two or more masters simultaneously initiate data transfer systems. • Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard mode or up to 400 KBit/s in the fast mode.

With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.
