items used for the experiment. 3. The dial gauge was observed to understand how to read it. The initial length Lo was marked on the apparatus‚ and the room temperature. 4. When the water boiled the temperature of the bar was noted with the thermocouple thermometer and the dial gauge reading was also noted. These are the initial conditions taken. 5. The bunsen burner was then turned off. 6. As the bar cooled‚ the temperature was noted as well as the dial gauge reading every ten degrees. From

GSM Based Control System CHAPTER 1 INTRODUCTION 1 GSM Based Control System 1.0 Introduction to Project “GSM based Control System” implements the emerging applications of the GSM technology. Using GSM networks‚ a control system has been proposed that will act as an embedded system which can monitor and control appliances and other devices locally using built-in input and output peripherals. Remotely the system allows the user to effectively monitor and control the house/office appliances

Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire‚ or disc of copper between the poles of a magnet.[1] For electric utilities‚ it is the first process in the delivery of electricity to consumers. The other processes

The present work investigates the mechanical properties and tribological behavior of Al-B4C composites. Attempts were made to overcome the wetting problem between B4C and liquid aluminium at lower temperatures for promising the mechanical and tribological behaviour of the Al -B4C composites. AA6061-B4C particle reinforced composites were produced through casting route at 850ºC with K2TiF6 added as flux to overcome the wetting problem between B4C and liquid aluminium metal. The Aluminium B4C composite
