Abstract: Public distribution system i.e. rationing distribution is one of the widely controversial issues that involves corruption and illegal smuggling of goods. All these happen because every job in the ration shop involves manual work and there are no specific high-tech technologies to automate the job. Because of intervention of manual work there are lots of illegal activity occurs. The illegal activities are like, wrong entry in register of shop about the amount of products that given to the people, sometimes there is chance of distribution of low quality products than actual product provided by government for poor people, people do not have idea about how much quantity of good provided by government to them etc. In this paper we propose the concept about to replace manual work in public distribution system (rationing distribution system) by automated system which will be installing at the ration shop .In this automated system we replace the convectional ration card by smart card in which all the details of user provided. This prompted us to interface smart card reader (RFID Based) to the ARM. Government should have control over all transaction happen at ration shop, to involve government in the process we can connect the system which is at ration shop to the government database via GSM module.

Keywords: ARM, GSM, RFID.

Abstract: Today solar energy became an important resource of energy generation. But the efficiency of solar system is very low. To increase its efficiency MPPT techniques are used. The main disadvantage of solar system is its variable voltage. And to obtained a stable voltage from solar panels DC-DC converters are used . DC-DC converters are of mainly three types buck, boost and cuk. This paper presents use of cuk converter with MPPT technique. Generally buck and boost converters used. But by using cuk converter we can step up or step down the voltage level according to the load requirement. The circuit has been simulated by MATLAB and Simulink softwares.

Keywords: Cuk converter, MPPT, PV system, simulation

Abstract: This paper presents the modeling of Permanent Magnet Synchronous Motor and its application with Vector Control technique under different operating condition such shaping, cutting, grinding or shearing require constant torque, irrespective of speed. Other application in cranes and conveyors handling constant weight of material per unit time, in pumps, screw conveyors, compressors and ball mills, for traction drive. Simulation results shows that proposed system has high acceleration and retardation rate with vector control overall fast dynamic response as well as good controlling ability.

Abstract: The optimal sizing for power reliable Wind-PV hybrid system is time consuming and complex due to varying weather conditions and the corresponding system cost .This requires a novel sizing procedure which can able to find number of possible solution .This paper proposes a multi-Objective design procedure using the genetic algorithm (GA) and integer programming with LPSP concept which has the ability to attain the global optimum with relative computational simplicity to minimize system cost and Loss of supply probability.

Keywords: Wind/PV; standalone power systems; optimal configuration; genetic algorithms; mixed multiple criteria integer programming.

Abstract: The study of sleep has become very essential to diagnose the brain disorders and analysis of brain activities these days. Electroencephalogram (EEG) is a medical imaging tool for diagnosing, monitoring, and managing neurological disorders. Therefore it is necessary to analyse the different sleep stages, & sleep transients like K-complexes. But due to the non stationary and non linear behaviour of brain signals, it is very difficult to detect the K-complexes manually. In this paper two automated detection approaches are discussed based on Wavelet decomposition (DWT) and Statistical k-means using mahalnobis distance. The performance of these methods is considerably efficient & is a hardware independent solution to the biomedical signal processing field.

Keywords: DWT, K-complex, K-means algorithm.
