An internet search engine searches the internet‚ or select pieces of the internet‚ based on important words‚ they keep an index of the words they find and where they find them‚ and they allow users to look for words or combinations of words found in that index. Earlier search engines only had a few hundred thousand pages and document and only received around one or two thousand inquiries each day compared to the hundreds of millions of pages and tens of millions of queries per day now a days.

you agree with the idling engine ban? A few years ago‚ the Environmental Protection Department proposed to legislate the idling engine ban‚ under which all vehicles must switch off their engines. I totally disagree with the idling engine ban‚ for I think that this policy not only cannot bring benefits to pedestrians in air quality‚ but instead brings harm to drivers and passengers. To start with‚ the idling engine ban brings inconvenience to drivers. As the idling engine ban proposes that a driver

Evolution of the Jet Engine Thought the course of time man has constantly sought to better both himself and mankind through creation and invention. From the first time a caveman rubbed to sticks together and discovered fire to the design and development of the Saturn 5 rocket which propelled by that same fire carried man from the earth to the moon. One can argue over whether on not this invention or that was the greatest. I intend to focus my attention on evolution of just one of those technologies

Chapter 1 ENGINES 1.1. INTRODUCTION The term‚ Engine‚ coined from the French word Engin‚ is nothing new to engineers. Motors converting heat energy into motion are usually referred to as engines (Collins English Dictionary - Complete & Unabridged 10th Edition‚ 2010). The type of engine being focused on in this report is an Internal Combustion Engine (as shown in Fig 1.1) in which a fuel is burnt along with air to produce hot gases which are then used to generate the necessary power

The invention of the internal combustion engine is most probably the result of the developments of several individuals. Around 1780‚ Dutch scientist Christiaan Huygens built an engine that used gunpowder as a fuel‚ but this engine was far too dangerous to be practical. His assistant‚ Denis Papin‚ also experimented with developing an internal combustion engine‚ building a simple steam-powered device around 1790. Again‚ this engine was not practical‚ and not until the early nineteenth century did the

The Evolution of Jet Engines The jet engine is a complex propulsion device which draws in air by means of an intake‚ compresses it‚ heats it by means of an internal combustion engine‚ which when expelled it turns a turbine to produce thrust‚ resulting in a force sufficient enough to propell the aircraft in the opposite direction (Morgan 67). When the jet engine was thought of back in the 1920’s the world never thought it would become a reality‚ but by 1941 the first successful jet flight was
