1.数据库安装 （1）将实例目录“database”文件夹下扩展名为“.MDF”和“.LDF”的两个文件拷贝到SQL Server 2000安装路径下的“MSSQL”/“Data”目录下。 （2）打开SQL Server 2000中的“企业管理器”，然后展开本地服务器，在“数据库”数据项上单击鼠标右键，在弹出的快捷菜单中选择“所有任务”/“附加数据库”菜单项。 （3）在弹出的“附加数据库”对话框中选择刚拷贝过去的数据库文件（.MDF文件），单击【确定】按钮，即可完成数据库的附加操作。 2.在使用ADO技术时，需要导入一个ADO动态链接库msado15.dll，该动态库位于系统盘下的“Program Files\Common Files\System\ado\”目录下。 例：如果您的系统盘为C盘，则该文件位于“C:\Program Files\Common Files\System\ado”目录。

This project aim was to build wireless software modem for data communication between two computers using an acoustic interface in the voice frequency range (20Hz– 20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz – 20,000Hz) and the receiving antenna is a microphone (frequency response of: 100Hz – 16,000Hz). The test files used as information files were text files. This goal was attained both in an incoherent scheme and in a coherent scheme. Build under Matlab code, our modem uses OFDM (orthogonal frequency division multiplexing) modulation, synchronization by LMS sequence, channel estimation (no equalizer) via pilot tones. The symbols are either PSK or ASK for a constellation size of 2 or 4. To optimize the probability of error, these symbols were mapped using Gray mapping. Report

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.

The Fuzzy Clustering and Data Analysis Toolbox is a collection of Matlab functions. Its propose is to divide a given data set into subsets (called clusters), hard and fuzzy partitioning mean, that these transitions between the subsets are crisp or gradual.

Data mining (DM) is the extraction of hidden predictive information from large databases (DBs). With the automatic discovery of knowledge implicit within DBs, DM uses sophisticated statistical analysis and modeling techniques to uncover patterns and relationships hidden in organizational DBs. Over the last 40 years, the tools and techniques to process structured information have continued to evolve from DBs to data warehousing (DW) to DM. DW applications have become business-critical. DM can extract even more value out of these huge repositories of information.
