so that light cannot pass through them. Each crystal‚ therefore‚ is like a shutter‚ either blocking the light or allowing light to pass through. Some of the technologies behind liquid crystal display are as follows Illumination-A cold cathode fluorescent lamp that is situated behind the LCD panel is used as an external lighting mechanism as LCD panels produce no light of their own. The conventional backlit LCDs are now being widely replaced by two types of LED backlit LCD displays. Active Matrix-This

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power‚ a transistor can amplify a signal. Today‚ some transistors are

1. Havells’ proposed acquisition of Sylvania Limited Inc. (SLI) makes sense from a strategic point of view. Macroeconomic conditions and an increasing threat of competition give merit as to why this proposed acquisition makes strategic sense. The electrical and lighting industry is poised for a major growth spurt (page 3)‚ and this could pan out to be a lucrative time for companies such as Havells to begin investing in both these segments. Havells has become a dominant player in the switchgear market

A. ACOUSTIC 1.Introduction Good acoustical quality is critical for a classroom to function well for its intended principal purpose. In elementary school classrooms‚ most learning involves listening to the teacher and to each other (Goodland‚ 1983). Even quite modest amounts of background noise or reverberation (i.e.‚ many delayed reflections of the original sound) can interfere with speech perception and‚ consequently‚ can impair educational outcomes. Speech intelligibility studies indicate that

The light bulb for many decades has changed the physical world we live in. “At the time‚ most people in cities illuminated their homes and offices with lamps that burned gas delivered to the premises by local gas companies” (Tagliaferro 51). With the invention of the light bulb it lit up work places‚ schools‚ libraries‚ streets‚ and homes. It changed how we lived and gave us the opportunity to see in the
