EXECUTIVE SUMMARY
Prior to the eighties and nineties, national media system was typified by domestically owned radio, television and newspaper industries. There was major import markets for films, TV shows, music and books, and these markets tended to be dominated by U.S. based firms. But local commercial interests, sometimes combined with a state-affiliated broad- casting service, predominated within the media system. All of this is ....etc

ABSTRACT
The rapid development of electronic systems in automotive vehicles has been driven for decades
by constantly growing requirements of legislation for environmental protection, as well as rising
demands of the end-user to improve fuel economy, safety, driving comfort and driving
excitement. The manufacturers of mobile work machines also see themselves increasingly
confronted with these requirements. Can Robert Bosch GmbH use the technical experiences
from automobiles also in this area to efficiently 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

GPRS DRIVING WAP ON THE ROAD TO 3G
ABSRTACT
Mobile telephony allowed us to talk on the move. The Internet turned raw data into helpful services that people found easy to use. Now, these two technologies are converging to create third generation mobile services. In simple terms, third generation (3G) services combine high-speed mobile access with Internet Protocol (IP)-based services. But this doesnâ„¢t just mean fast mobile connection to the world wide web. Rather, it means whole new ways to communicate, access information, conduct busi ....etc

Introduction

Windpower technology dates back many centuries. There are historical claims that wind machines which harness the power of the wind date back beyond the time of the ancient Egyptians. Hero of Alexandria used a simple windmill to power an organ whilst the Babylonian emperor, Hammurabi, used windmills for an ambitious irrigation project as early as the 17th century BC. The Persians built windmills in the 7th century AD for milling and irrigation and rustic mills similar to these early vertica ....etc

Abstract—In this paper, we study the availability of TV white spaces in Europe. Specifically, we focus on the 470-790 MHz UHF band, which will predominantly remain in use for TV broadcasting after the analog-to-digital switch-over and the assignment of the 800 MHz band to licensed services have been completed. The expected number of unused, available TV channels in any location of the 11 countries we studied is 56 percent when we adopt the statistical channel model of the ITU-R. Similarly, a person residing in these countries can expect to en ....etc

ABSTRACT
Third generation is the generic term used for the next generation of mobile communications systems. 3G will provide enhanced services to those - such as voice, text and data - predominantly available today.
Video on demand, high speed multimedia and mobile Internet access are just a few of the possibilities for users in the future. 3G Services will expand the possibilities of information and communication.
UMTS is a part of the International Telecommunications Union's (ITU's) 'IMT ....etc

The demand for organic food continues to increase in the United States and Europe. In the US,
organic certification to the National Organic Standards is required for all organic sales. Europe
has similar organic standards but separate certification requirements that must be met in order to
gain access to the European organic market.
United States Organic Standards
The US National Organic Program (NOP) was fully implemented on Oct. 21, 2002. The NOP is
a federal law that requires all organic food products to meet the same standards and be ....etc
