DirectX not only provides fast access to the hardware and therefore incredibly speedy performance, but it also makes it much easier for hardware developers to produce new devices that work well in the Windows environment. The DirectX APIs take away the necessity of writing your own low-level, device-specific code to access hardware such as the display adapter and network card, making it much easier for you to write programs that take full advantage of the computer s multimedia capabilities.

基于USB接口的数据采集模块的设计与实现Design and Implementation of USB-Based Data Acquisition Module路 永 伸(天津科技大学电子信息与自动化学院，天津300222)摘要文中给出基于USB接口的数据采集模块的设计与实现。硬件设计采用以Adpc831与PDIUSBDI2为主的器件进行硬件设计，采用Windriver开发USB驱动，并用Visual C十十6.0对主机软件中硬件接口操作部分进行动态链接库封装。关键词USB 数据采集Adpc831 PDNSBDI2 Windriver动态链接库Abstract T hed esigna ndim plementaitono fU SB-BasedD ataA cquisiitonM oduleis g iven.Th ec hips oluitonm ainlyw ithA dpc831a ndP DTUSBD12i sused for hardware design. The USB drive is developed场Wmdriver, and the operation on the hardware interface is packaged into Dynamic Link Libraries场Visual C++6.0. Keywords USB DataA cquisition Adttc831 PDfUSBD12 Windriver0 引言US B总 线 是新一代接口总线，最初推出的目的是为了统一取代PC机的各类外设接口，迄今经历了1.0,1.1与2.0版本3个标准。在国内基于USB总线的相关设计与开发也得到了快速的发展，很多设计者从各自的应用领域，用不同方案设计出了相应的装置[1,2]。数据采集是工业控制中一个普遍而重要的环节，因此开发基于USB接口的数据采集模块具有很强的现实应用意义。虽然 US B总线标准已经发展到2.0版本，但由于工业控制现场干扰信号的情况比较复杂，高速数据传输的可靠性不容易被保证，并且很多场合对数据采集的实时性要求并不高，开发2.0标准产品的成本又较1.1标准产品高，所以笔者认为，在工业控制领域，目前开发基于USB总线1.1标准实现的数据采集模块的实用意义大于相应2.0标准模块。

数字运算，判断一个数是否接近素数 A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value. Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not. Input Each line of input contains the base b, followed by a string of digits representing a positive integer in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone. Output For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise. Sample Input 10 111 2 110 10 123 6 1000 8 2314 0 Sample Output yes yes no yes no

This file contains a new and improved version of the Huffman coder, (June 29. 2001). The name is Huff06.m. There are also some additional files which are helpful when using Matlab for data compression: quantizer, different variants of run-length-encoding and end-of-block coding in Mat2Vec, and a program which do JPEG-like entropy coding. A complete compression example is shown in TestMat2Vec.m. This file is all you need for Huffman coding in MatLab.

This example application is a collection of Flash Lite do s and don ts from the usability point of view. The application contains real examples and animations of static examples that help you to see problematic issues in real life on a Nokia device. The application is optimized for devices with the resolution 170 x 208 pixels used in portrait mode. This example application is closely related to the document Flash Lite: Visual Guide, and it is highly recommended to read the document before going through this example.

This book is the most accurate and up-to-date source of information the STL currently available. ... It has an approach and appeal of its own: it explains techniques for building data structures and algorithms on top of the STL, and in this way appreciates the STL for what it is - a framework. Angelika Langer, Independent Consultant and C++ Report Columnist "A superbly authored treatment of the STL......an excellent book which belongs in any serious C++ developer s library." Jim Armstrong, President 2112 F/X, Texas. \n The C++ Standard Template Library (STL) represents a breakthrough in C++ programming techniques. With it, software developers can achieve vast improvements in the reliability of their software, and increase their own productivity.

Developers use algorithms and data structures every day of their working lives. Having a good under-standing of these algorithms and knowledge of when to apply them is essential to producing softwarethat not only works correctly, but also performs efficiently. This book aims to explain those algorithms and data structures most commonly encountered in day-to-day software development, while remaining at all times practical, concise, and to the point, with little orno verbiage to distract from the core concepts and examples.
