In recent years wireless sensor networks are widely used in many automated system like vehicle monitoring, heavy duty plants, robotic control etc. one of the best automated systems is the smart irrigation system. In this paper we have proposed a simple and cost effective smart irrigation system. Our system deploys wireless sensor motes from a wireless(More)
The theory of Rough set is a new mathematical tool to deal with intelligent data mining proposed by Z Pawlak. This paper implements the concept of tolerance relation on incomplete information system using variable precision rough set(VPRS) with flexible classification, which is an extension to the classical rough set theory. Here we have analyzed a cancer(More)
This paper uses super capacitor as the energy storage device for the DVR to compensate voltage sag, voltage swell and harmonics due to addition of nonlinear load in the distribution line. Based on this topology, DVR consist of super capacitor, z source inverter and injection transformer. Super capacitor produces the necessary dc voltage which is given as(More)
This paper presents simulation model of a single phase simplified eleven-level inverter (SELI). Multilevel inverter offers high power capability. Its performance is highly superior to that of conventional two-level inverter due to reduced harmonic distortion, lower electromagnetic interference and higher dc link voltage. The inverter is capable of producing(More)
Public transport especially buses are getting crowded day-by-day due to heavy demand of transport facility. More over the frequency of the buses are unregulated. Either the buses lines up at one time or buses get delayed for a long time. This kind of chaos is mainly due to irregular Planning of bus intervals and not knowing the details of the amount of(More)

We envision a future where any programmer can automatically generate an embedded device from application code. A future in which a professional embedded engineer can "sketch" out a partial device design and automation can complete it, in which a hobbyist can write a program and, in a matter of days, receive a custom hardware in the mail. Building this(More)
