i-DEN Integrated Digital Enhanced Network

Integrated Digital Enhanced Network, commonly referred to as iDEN, is a mobile communications technology, developed by Motorola, which provides its users the benefits of a trunked radio and a cellular telephone.

Sprint Nextel is the largest US retailer of iDEN services. iDEN places more users in a given spectral space, compared to analog cellular systems, by using time division multiple access (TDMA). Up to six communication channels share a 25 kHz space ....etc

Abstract
The present network-layer multicast routing protocols build multicast trees based only on hop count and policy. If a tree cannot meet application require- ments, the receivers have no alternative. A general and modular architecture that integrates alternate path routing with the network multicast services is proposed. This enables individual multicast receivers to reroute a multicast tree according to their needs, subject to policy restrictions. Many Internet multicast applications such as teleconferencing and remote diagnosis have Q ....etc

MICROBIAL ENHANCED OIL RECOVERY (MEOR)

Microbial consortia activity within an oil and gas reservoir is a potentially powerful biological system that can profoundly affect the entire reservoir. Certain species of microorganisms can be manipulated and controlled to release trapped oil in significant and economic quantities. Some microbial methods aid inn paraffin removal while others are designed to modify heavy oil. Still other micro-organisms produce chemicals, such as surfactants, polymers, or solvents that are useful in oil recovery proces ....etc

Rapid advances in silicon technology and high demand of multimedia applications on wireless networks have spurred the research and development of computationally intensive signal processing and communication systems on FPGAs and Application Specific Integrated Circuits (ASICs).

These advancements also offer mystical solutions to historically intractable signal processing problems resulting in major new market opportunities and trends. Traditionally for signal processing specific applications off the shelf Digital Signal Processors (DSPs) ar ....etc

Abstract
An ad hoc network is the cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or exist- ing infrastructure. Because of the node movement the routes will fail randomly. For communication to occur between hosts that are not within each others range, routes involving intermediate nodes must be established; however, since the hosts may be in motion, a host that was part of a route may move away from its up- stream and downstream partners, thus breaking t ....etc

The first stepping stone in migration path to third generation wireless mobile services (3G) is the General Packet Radio Services, GPRS, a packet-switched technology that delivers speeds of up to 115kbps. If GPRS is already in place, Enhanced Data rates for Global Evolution (EDGE) technology is most effective as the second stepping stone that gives a low impact migration. Only software upgrades and EDGE plug-in transceiver units are needed. The approach protects operators' investments by allowing them to reuse their existing network equipment a ....etc

ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the
c ....etc
