18INTRODUCTION In history of railways , almost 90% of the accidents happens because of two reasons: Train comes away from track Track discontinuity TRAIN COMES AWAY FROM TRACK It means that track is not all problems but train moves out of track. This happens because Of lack of concentration of the people who works with track.  For example when the nuts and bolts get loosed these sorts of problems ...

0Abstract The past four decades has been a period in which have seen revolutionary changes happening in our countrywide, for wind energy resources development projects. Beside a huge number of small irrigation and wind power schemes, more than 3000 large and small projects of wind mill have been constructed all over the country. All structures/project harnessing water need gates for controlling the ...

0Abstract This project is an innovative solution to operate a machine / motor / liquid pumps for a small duration. If a machine is to be operated for ten minutes, and should be switched off after the duration, it is too difficult and many times we forget to switch it off the system after the prescribed time. This project provides the facility of automatic switch off after the requited time duration. ...

1Abstract There are several ways to convert an AC voltage at a wall receptacle into the DC voltage required by a microcontroller. Traditionally, this has been done with a transformer and rectifier circuit. There are also switching power supply solutions, however, in applications that involve providing a DC voltage to only the microcontroller and a few other low-current devices, transformer-based or ...
