Now a days every advertisement is going to be digital. The big shops and shopping centers are using the digital moving displays now. In Railway station and bus stands everything that is ticket information, platform number etc is displaying in digital moving display. But in these displays if they want to change the message or style they have to go there and connect the display to PC or laptop.Suppose the same message if the person wants to display in main centers of the cities means he have to go there with laptop and change the message by conne ....etc

Applications of Majority Gates with Quantum-Dot Cellular Automata(QCA)

Not much research was done on the circuits based on majority gates, as the incompatibilities in hardware donâ„¢t permit the CMOS technologies to do so. But this emerging computational nanotechnology called the quantum-dot cellular automata (QCA) has been a great help in learning more about the majority Gates, as it happens to be its primary logic primitive. Characterizing the three variable Boolean function to a simplified m ....etc

CHAPTER 1
INTRODUCTION

Molecular electronics seeks to build computational systems, both memory and logic, wherein individual or small collections of molecules serve as discrete device components. Potential advantages of molecular electronic systems could be many-fold including reducing the complexity and cost of current integrated circuit fabrication technologies, reducing heat generation by using only a few electrons per bit of information, and providing a route to meet the ever-continuing demand for miniaturiza ....etc

Present project is designed using 8051 microcontroller to avoid railway accidents happening at unattended railway gates, if implemented in spirit. This project utilizes two powerful IR transmitters and two receivers; one pair of transmitter and receiver is fixed at up side (from where the train comes) at a level higher than a human being in exact alignment and similarly the other pair is fixed at down side of the train direction. Sensor activation time is so adjusted by calculating the time taken at a certain speed to cross at least one compart ....etc
