this is a document about radio frequency identification RFID, this was a project ,i have done last year ,actually this technology is a very inpotrtant one due to its relation with newest technologies , like GPS , or the miniturization of integrated circuits ,and that is described in chapter 3 . chapter 1 gives an introduction of the technology RFID , chapter 2 gives a discussion of a library using RFID , and chapter 3 is about the future of RFID , and finally the conclusion .

Implementing+802.11

Communication, a word that many associate with modern technology, actually has nothing to do with technology. At its core, communication involves nothing more than the spoken or written word, and symbolic languages like art and music. Technology has become synonymous with communication because technology has historically been the method by which communication to or by the general population takes place.

Mobile+Communications+Engineering

By definition, the term “mobile-radio communications” describes any radio communication link between two terminals of which one or both are in motion or halted at unspecified locations and of which one may actually be a fixed terminal such as a base station. This definition applies to both mobile-to-mobile and mobile-to-fixed radio communica- tion links. The mobile-to-mobile link could in fact consist of a mobile- to-fixed-to-mobile radio communication link.The term “mobile” applies to land vehicles, ships at sea, aircraft, and communications satellites. In tactical situations, mobile-radio systems may include any or all of these types of mobile terminals.

Standardization+in+Smart+Grids

One of the predominant topics in the domain of the emerging Smart Grid can be seen in standardization. With the combination of existing protection and automa- tion technology with upcoming ICT-based solutions, different interoperability is- sues arise when technologies have to be combined in the infrastructure. Standards have proven to be one of the most striking solutions to actually cope with this topic. Since 2008, this topic has gained much attention in various political and technical agendas.

高效率射頻微波固態功率放大器

Research on microwave power amplififiers has gained a growing importance demanded by the many continuously developing applications which require such subsystem performance. A broad set of commercial and strategic systems in fact have their overall performance boosted by the power amplififier, the latter becoming an enabling component wherever its effificiency and output power actually allows functionalities and operating modes previously not possible. This is the case for the many wireless systems and battery-operated systems that form the substrate of everyday life, but also of high-performance satellite and dual-use systems.

TI反激變換器變壓器設計相關資料

This Section covers the design of power transformers used in buck-derived topologies: forward converter, bridge, half-bridge, and full-wave centertap. Flyback transformers (actually coupled inductors) are covered in a later Section. For more specialized applications, the principles discussed herein will generally apply.
