With the ever-increasing demand for energy, we have to focus our attention on greener alternatives. The main problems with non-conventional energy sources are that they need storage. Flywheel batteries seem to solve this problem to a great extend. Flywheel energy storage systems are non-polluting; need no replacement and little maintenance. The basic working of flywheel batteries and their applications are discussed in brief. Flywheel batteries stores energy as rotational kinetic energy of the flywheel and this energy can be retrieved either th ....etc

Technology has advanced to the point where realism in virtual reality is very achievable. However, in our obsession to reproduce the world and human experience in virtual space, we overlook the most important aspects of what makes us who we are”our reality. One must capture the imagination in order to create truly compelling experiences.Augmented reality will truly change the way we view the world. Picture yourself walking or driving down the street. With augmented-reality d ....etc

Wi-Fi, or Wireless Fidelity is freedom :it allows you to connect to the internet from your couch at home, in a hotel room or a conferance room at work without wires . Wi-Fi is a wireless technology like a cell phone. Wi-Fi enabled computers send and receive data indoors and out; anywhere within the range of a base station. And the best thing of all, it is fast.
However you only have true freedom to be connected any where if your computer is configured with a Wi-Fi CERTIFIED radio (a PC card or similar dev ....etc

HIGH SPEED TRAINS
1. INTRODUCTION
When English inventor Richard Trevithick introduced the steam locomotive on 21 February 1804 in Wales, it achieved a speed of 8 km/h (5 mph). In 1815, Englishman George Stephenson built the world's first workable steam locomotive. In 1825, he introduced the first passenger train, which steamed along at 25 km/h (16 mph). Today, trains can fly down the tracks at 500 km/h (311 mph). And fly they do, not touching the tracks.
There is no defined speed at which you can call a train a high spee ....etc

ABSTRACT

A novel data-hiding methodology, denoted as digital invisible ink (DII), is proposed to implement secure steganography systems. Like the real-world invisible ink, secret messages will be correctly revealed only after the marked works undergo certain prenegotiated manipulations, such as lossy compression and processing. Different from conventional data-hiding schemes where content processing or compression operations are undesirable, distortions caused by prenegotiated manipulations in DII-based schemes are indispensable steps for ....etc

Introduction
Industries handling dangerous materials continuously
identify hazards and manage risk. One of the major
hazards in process or manufacturing industry is the
release of toxic chemicals. The hazard arising from a
toxic release depends on the toxicity of the chemical
and the conditions of exposure. The effects from the
exposure to toxic release c ....etc

A cyborg is a cybernetic organism (i.e., an organism that has both artificial and natural systems). The term was coined in 1960 when Manfred Clynes and Nathan Kline used it in an article about the advantages of self-regulating human-machine systems in outer space. D. S. Halacy's Cyborg: Evolution of the Superman in 1965 featured an introduction by Manfred Clynes, who wrote of a new frontier that was not merely space, but more profoundly the relationship between 'inner space' to 'outer space' -a bridge...between mind and matter.

Abstract

A measurement campaign has been carried out in 400kV air insulated electricity substation to characterise and model radio frequency impulsive noise with a view to assessing its impact on wireless network technologies. The relatively recent availability of new technologies such as WiFi, Bluetooth and Zigbee means that particular emphasis has been put on higher frequency bands (e.g. 2.4, 5 GHz) than have previously been investigated. A detection system to measure wideband noise over a spectrum extending up to 5.1 GHz ....etc

ABSTRACT
The Mobile IP protocol was designed to support seamless and continuous Internet connectivity for mobile computing devices such as notebook PCs, cell phones, PDAs, etc. Utilizing Mobile IP, the mobile computing device is able to stay connected as it moves about and changes its point of attachment to the Internet. Both home and local resources, such as location based services, instant messaging, and email, are continuously accessible.
This paper discusses the basic architecture and working of mobile ip, various is ....etc
