Abstract;
In order to examine the validity of model at organic/metal interfaces, the position of the vacuum level of N,N'-bis(3-methylphenyl)-N,N'-diphenyl--4,4'-diamine (TPD) film formed on various metal substrates (Au, Cu, Ag, Mg and Ca) was measured as a function of the film-thickness by Kelvin probe method in ultrahigh vacuum (UHV). TPD is a typical hole-injecting material for organic electroluminescent devices. At all the interfaces, sharp shifts of the vacuum level were observed within 1 nm thickness. Further deposition o ....etc

The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM). Frame relay and ATM have become t ....etc

INTRODUCTION

The average person has a small home, but a huge appetite for entertainment. All of us would want to zap video images from digital camcorders to our hard drives without tripping over the cables that connect them. As home entertainment systems become more sophisticated, u will have flat panel displays. You could hang them like paintings on your wall¦..Now who would want cables to dangle from those beauties?

So you think - big deal¦. We have Bluetooth and 802.11 wireless technologies to solve this problem. They do a dece ....etc

ABSTRACT

Mankind has come across many stages right from ancient Stone Age to the modern wireless age. In every stage it developed its own unique method of communication to suit its requirements. These methods range from Graham Bellâ„¢s cabled telephones to todayâ„¢s wireless mobile handsets. But if there could be a technology such that ....etc

HIGH THROUGHPUT AND LOW POWER REED SOLOMEN DECODER FOR ULTRA WIDE BAND FREQUENCIES

Abstract:- Reed Solomon (RS) codes have been widely used in a variety of communication systems such as space communication link, digital subscriber loops and wireless systems, as well as in networking Communications and magnetic and data storage systems. Continual demand for ever-higher data rates and storage capacity makes it necessary to devise very high-speed implementations of RS Decoders. Newer and faster implementations of the decoder are being developed ....etc

Design and development of X-band micro strip patch antenna

Introduction


In high-performance aircraft, spacecraft, satellite and missile applications, where size, weight, cost, performance, ease of installation, and aerodynamic profiles are constraints, low profile antennas may be required. These antennas should have low profile, conformable to planar and non-planar surfaces, simple and inexpensive to manufacture using modern printed-circuit technology, mechanically robust when mounted on rigid surfaces, compatible with MMIC designs, and ....etc
