Modern day Flight Data Recorders receive inputs via specific data frames from the flight-data acquisition units. They record significant flight parameters, including the control and actuator positions, engine information and time of day. There are 88 parameters required as a minimum under current U.S. Federal regulations (only 29 parameters were required until 2002). It is proposed to design minimal flight recorder with 5 to 6 parameters like temperature of the engine, engine noise, vibration, position, altitude etc... And transmit the data to the remote server. This data can be sent by wireless technology every 10 seconds and can be modified later on with advanced wireless communication. It is proposed to use GPS device to find out the aircraft position and altitude of the aircraft. Using advanced RISC microcontroller and electronic sensor other parameters mentioned are monitored. Using wireless modem all the data is sent to base station, another PC server with wireless modem. Here...4631 Руб.
In information technology data plays a vital role. On the basis of data it used to process the information or do our day-to-day activities. More databases are available in the IT world to store or retrieve data in different manner or to maintain. So many organizations have released databases; Oracle is considered the best one. There are RDBMS, DBMS, and FILE SYSTEMS database. RDBMS is successful for the end user or programmer and developers. But Oracle database is reliable and user friendly and it supports network. In the Oracle database access control is possible and at the same we can create new user with possible security for the user. Oracle administration can be done within a campus or in front of a server provided that the server should be a wired network. For the Data Base management the Administrator or Data Base user must sit before the Data Base Server or access the sever within the campus. This is a disadvantage for the user as well as the administrator if they...4631 Руб.
Limitations of electrical wires result in distortion and dispersion of the signal for long distances. That have emerged optical communication as the only way of communication for long distances. For medium distances optics can support the high data rates required by the latest applications. Optical networks are becoming the dominant transmission medium as the data rate required by different applications increases. The bottleneck for implementing optical instead of electric networks for medium distances, like local area network, is the cost of the optical components and the cost of replacing the existing copper network. This book will discuss the possible cost benefits that come from the use of different materials like plastic optical fiber instead of silica fiber or Si, Si/Ge instead of InP or GaAs for the transceiver as well as the trade offs between the performance and cost when discrete transceiver is replaced by the monolithically integrated transceiver, by using a process based...2259 Руб.
