The computerise electronic identification system is a system design to enable us assign electronic identification code to every staff and student for effective monitoring and management of staff and students by the institutions. This process was achieved by using a passive card (MIFARE, ISO 14443 A) for the identity card and a Total Wireless Reader (TWR PRO) as the RFID reader. The Microsoft Visual Studio 2012 was use to develop the Graphic User Interface environment (GUI). The C# programming language was used to implement the system and the .NET frame work 4.5 is used for the frame work. The Microsoft access database was used because of its portability The database was created by entering the individual data into the system and this information was used to generate electronic Id which was encoded in the chip contained in the passive card by placing the card close to the Rfid device. The accuracy of the system was tested by selecting 36 students with their passive identity cards and ask them to go into the classroom were the Rfid have been set up and the system was able to read the cards and generate report within five minutes.

Radars are primarily used to detect and identify moving objects, so the multi-axis drive system is one of the most important parts that directly affect the quality and versatility of the radar station. In the problem of control of the two axes of the radar station, we always need to consider many things at the same time such as variable dynamic parameters, the movement of one axis affected by the other, the requirement for accurate traction, the need for wave interference. An adaptive robust control designed to satify the quality requirement, with flexible structure which reduces the amount of computation is proposed in this paper.

Oil/Gas offshore extraction involves long feeders being used to supply power to Induction motors. Modeling previously was done ignoring effects of long feeders and line parameters. We design a model considering Long feeder effects and use of inverter output filters. We considered Field oriented control technique. Due to subsea applications we implement control technique at stator side itself. Stator values are measured and then transformed from three phase to 2 phase values using Clarke transform blocks. Long feeder is modelled as a p-model equivalent considering lump parameters.LC filter is used at inverter output to improve output response. Transformed values are fed to the designed controller which again feeds signal to inverter via SVPWM. Simulation and experiments show that model can be effectively controlled from stator side, LC filter helps to obtain a near sinusoidal output response and also helps to reduce harmonics and dv/dt rising of output voltage.
