Abstract: In today's restaurant Digital multi-touch menu cards and other forms of digital facility are replacing old fashioned services like- waiters can take order from customer and serve them. Intelligent Restaurant system delivering almost infinite flexibility in promoting meal and snack options. Intelligent Restaurant system uses technologies innovatively in a modern restaurant such as multi-touch LCD with Arduino mega, RF module, database & line following Robot to enhance quality of services and to enrich customers' dining experience. A line following robot is designed using sensor operated motors to keep track the line path predetermined for meal serving. PayPal is used for online payment.

Keywords: Line following robot, Multi-touchable module, RF module, PayPal, Database.

Abstract: Whenever a series compensated transmission line is connected across the transmission line there exists a problem known as Sub-Synchronous Resonance at particular impedance. This will lead to damage of the turbine shafts and other major parts of the generator. So, this can be avoided by the use of the FACTS devices[1,2] supplemented with the auxiliary control devices[3-7]. Many FACTS controllers have been proposed by using GCSC, TSSC,TCSC etc., But, the damping can be best obtained by the use of the Distributed Static Series Compensator along with controlled with the Fuzzy Logic based Damping Controller(FLDC). This paper mainly deals with the reduction of the oscillations that occur due to the SSR by using FLDC and also the comparison is made with the convention\al PI controller in order to get best view of the performance of FLDC.

Abstract:A closed loop control of the fourth order (LCLC configuration) resonant converter has been simulated and presented in this paper. The PI controller has been used for closed loop operation and the performance of proposed converter has been estimated with the closed loop and the open loop condition. The steady state-transient responses of nominal load, sudden line and load disturbances have been obtained to validate the controller performance. The proposed approach is expected to provide better voltage regulation for
dynamic load conditions.
