Asynchronous connection
The interconnected AC networks that tie the power generation plants to the consumers are in most cases large. The map below shows the European situation.
There is one grid in Western Europe, one in Eastern Europe, one in the Nordic countries. Islands like Great Britain, Ireland, Iceland, Sardinia, Corsica, Crete, Gotland, etc. also have their own grid with no AC connection to the continent. The oth ....etc

THE INTERNATIONAL SPACE STATION (ISS)
In 1984, President Ronald Reagan proposed that the United States, in cooperation with other countries, build a permanently inhabited space station. Reagan envisioned a station that would have government and industry support. The U.S. forged a cooperative effort with 14 other countries (Canada, Japan, Brazil, and the European Space Agency -- United Kingdom, France, Germany, Belgium, Italy, The Netherlands, Denmark, Norway, Spain, Switzerland, Sweden). During the planning of the ISS and after the fall of th ....etc

Experts agree that the biggest drain of energy takes place when a vehicle blasts off, pushing through Earth?s gravitational pull requires great amounts of fuel, but once they get out of our atmosphere, the rest is easy.

If you could cut out that ?blast off? portion, space travel would be easier and much more fuel-efficient.

In a Space Elevator scenario, a Maglev vehicle would zoom up the side of an exceedingly tall structure and end up at a transfer point where they?d then board a craft to the Moon, Mars, or any other distant destination ....etc

INTEGRATING SPEECH ENGINE WITH WEB NAVIGATOR

Abstract



Finding information on the web is like looking for a needle in a haystack. Fortunately there are stating points one can use. Tools are also available to help perform searches for specific data. It is the browser that helps communicate with the Internet world. A browser is a program that takes input as a page requested; interprets the text, formats the commands that t ....etc

The successful explortion of space requires a system that will reliably transport payloads into space and return back to earth; without subjecting them an uncomfortable or hazardous environment. In other words, the space crafts and its pay loads have to be recovered safely into the earth. The space shuttle used at older times were not re-usable. So NASA invented re-usable space shuttle that could launch like a rocket but deliver and land like an aeroplane. Now NASA is planning to launch a series of air-breathing planes that would ....etc

Bottlenecks
Constrained transmission paths or interfaces in an interconnected electrical system
The term Bottlenecks is often interchangeable to congested transmission paths or interfaces. A transmission path or interface refers to a specific set of transmission elements between two neighboring control areas or utility systems in an interconnected electrical system. A transmission path or interface becomes congested when the allowed power transfer capability is reached under norma ....etc

Robot is a mechanical body with the brain of a computer. Integrating the sensors and the actuators and with the help of the computers, we can use it to perform the desired tasks. Robot can do hazardous jobs and can reach places where it?s difficult for human beings to reach. Robots, which substitute the manned activities in space, are known as space robots. The interest in this field led to the development of new branch of technology called space robotics. Through this paper, I intend to discuss about the applications, environmental condition, ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

Robot is a system with a mechanical body, using computer as its brain. Integrating the sensors and actuators built into the mechanical body, the motions are realised with the computer software to execute the desired task. Robots are more flexible in terms of ability to perform new tasks or to carry out complex sequence of motion than other categories of automated manufacturing equipment. Today there is lot of interest in this field and a separate branch of technology 'robotics' has emerged. It is concerned with all problems of rob ....etc
