Serial Port The microcontroller AT89C51 has an inbuilt UART for carrying out serial communication. The serial communication is done in the asynchronous mode. A serial port‚ like other PC ports‚ is a physical interface to establish data transfer between computer and an external hardware or device. This transfer‚ through serial port‚ takes place bit by bit. IBM introduced the DB-9 RS-232 version of serial I/O standard‚ which is most widely used in PCs and several devices. In RS232‚ high and

To enable this level of control‚ configuration and authentication data is sent over the network between the remote computer and the local Windows Media server computer. As the data is sent‚ it is vulnerable to unauthorized access. You can add the IIS security measures to your site to provide different levels of protection. Most of the configuration is performed by changing

I NTRODUCTION It has been known that use of multiple antennas at transmitter and receiver increases speed of data transmission between communication terminals. However‚ MIMO channel capacity is degraded by correlation and keyhole effects. Because of the keyhole effect [1]‚ [2]‚ the rank of MIMO channel matrix is reduced to one‚ even in the absence of antenna correlation

PROCESSING OF DATA INTRODUCTION Data processing is an intermediary stage of work between data collection and data analysis. The completed instruments of data collection‚ viz.‚ interview schedules/ questionnaires/ data sheets/field notes contain. a vast mass of data. They cannot straightaway provide answers to research questions. They‚ like raw materials‚ need processing. Data processing involves classification and summarisal1on of data in order to make them amenable to analysis Processing of data requires

Data Preprocessing 3 Today’s real-world databases are highly susceptible to noisy‚ missing‚ and inconsistent data due to their typically huge size (often several gigabytes or more) and their likely origin from multiple‚ heterogenous sources. Low-quality data will lead to low-quality mining results. “How can the data be preprocessed in order to help improve the quality of the data and‚ consequently‚ of the mining results? How can the data be preprocessed so as to improve the efficiency and ease
