基于MATLAB软件仿真设计FIR滤波器，然后对噪声信号进行去噪，从而改善语音信号的质量。本文滤波器设计的方法则是采用简单的窗函数（凯撒窗）来设计的，并利用MATLAB作为编程工具完成一些数据的计算以及绘制出去噪前后的时域图和频谱图。通过对比去噪前后的时域图和频谱图，或者通过生成的声音文件，分析说明出滤波器设计的正确性。(The FIR filter is designed based on MATLAB software, and then the noise signal is de noised to improve the quality of speech signal. The method of designing the filter in this paper is designed by using a simple window function (Kai Sachuang), and using MATLAB as a programming tool to complete the calculation of some data and to draw the time domain diagram and spectrum map before and after the denoising. By comparing the time domain and frequency spectrum before and after the noise elimination, or through the generated sound files, the correctness of the filter design is illustrated.)

设计一个多功能数字钟，以一昼夜24小时为一个计数周期。准确计时，具有“时”“分”“秒”数字显示。整点能自动打点、报时。要求报时声响四低一高，最后一响为整点。具有校时功能。要求电路主要采用中小规模CMOS集成电路。要求电路尽量简化，并选用同类型的器件。在EWB电子工作平台上进行电路的设计和计算机仿真。-The design of a multi-function digital clock, 24 hours a day for a cycle count. Accurate time, a

关于isp的一个测试程序，能够实现简单的测试-Isp on a test procedure that can realize simple test

本书的风格跟C语言的经典《The C Programming Language》相似，作者同样也是著名技术作家和语言缔造者的组合。本书与一般的Ruby语言图书相比，除了介绍如何使用Ruby语言外，还讲述了Ruby的实现原理及内部运作机制。堪称Ruby之经典之作(The Ruby Programming Language is the authoritative guide to Ruby and provides comprehensive coverage of versions 1.8 and 1.9 of the language. It was written (and illustrated!) by an all-star team: • David Flanagan, bestselling author of programming language "bibles" (including JavaScript: The Definitive Guide and Java in a Nutshell) and committer to the Ruby Subversion repository. • Yukihiro "Matz" Matsumoto, creator, designer and lead developer of Ruby and author of Ruby in a Nutshell, which has been expanded and revised to become this book. • why the lucky stiff, artist and Ruby programmer extraordinaire. This book begins with a quick-start tutorial to the language, and then explains the language in detail from the bottom up: from lexical and syntactic structure to datatypes to expressions and statements and on through methods, blocks, lambdas, closures, classes and modules. The book also includes a long and thorough introduction to the rich API of the R)

用C#写的一个小东东，可以对进程进行专杀，和对文件进行监控，这是整个工程-With C# Write a small Dongdong can process designed to kill, and to monitor the document, which is the whole project

这是一个基于gensim的倒排表，同时也含有手动实现的部分(This is an inverted table based on gensim, and also contains manual implementation.)

将各个项目子目录拷贝到硬盘上,然后可以用Visual Basic打开程序(Copies all subdirectories to the hard disk, and then can open the program with Visual Basic)

说明：  本书采用大量图片，通过详细的分步讲解，以直观、易懂的方式展现了7个数据结构和26个基础算法的基本原理。第1章介绍了链表、数组、栈等7个数据结构；从第2章到第7章，分别介绍了和排序、查找、图论、安全、聚类等相关的26个基础算法，内容涉及冒泡排序、二分查找、广度优先搜索、哈希函数、迪菲 - 赫尔曼密钥交换、k-means 算法等。 本书没有枯燥的理论和复杂的公式，而是通过大量的步骤图帮助读者加深对数据结构原理和算法执行过程的理解，便于学习和记忆。将本书作为算法入门的第一步，是非常不错的选择。(This book uses a large number of pictures, through detailed step-by-step explanation, in an intuitive and easy to understand way to show the basic principles of 7 data structures and 26 basic algorithms. Chapter 1 introduces seven data structures such as linked list, array and stack; from Chapter 2 to Chapter 7, 26 basic algorithms related to sorting, searching, graph theory, security and clustering are introduced respectively, including bubble sorting, binary searching, breadth first search, hash function, Diffie Herman key exchange, K-means algorithm, etc. This book does not have boring theory and complex formula, but through a large number of step diagrams to help readers deepen the understanding of data structure principle and algorithm execution process, easy to learn and remember. This book as the first step of the algorithm, is a very good choice.)
