Integrating hybrid systems with existing thermal desalinationplants
(
Elsevier B.V.
, 2004 , Article)
In Gulf countries, most power plants are co-generation power desalting plants (CPDP) that generate electric energy and also produce fresh water through the desalination of seawater. This paper provides detailed technical ...
Aquifer storage and recovery (ASR): A strategic cost-effective facility to balance water production and demand for Sharjah
(
Elsevier B.V.
, 2004 , Article)
Aquifer storage and recovery was evaluated as a strategic water storage facility and as a tool to reduce overallcost of water production. This work investigated the size, cost, and mode of operation required to run the ...

Performance enhancement of relay-assisted communications via binary feedback
(
IEEE
, 2004 , Conference Paper)
This paper proposes a modified two-hop wireless communication system and studies its performance. The modified system has a reliable feedback channel that carries a binary signal from the receiver to inform the transmitter ...
Optimal power allocation for relayed transmissions over Rayleigh-fading channels
(
IEEE
, 2004 , Article)
Relayed transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several shorter links/hops. One of the main advantages of this communication technique ...
Performance of OFDM with M-QAM modulation and optimal loading over rayleigh fading channels
(
IEEE
, 2004 , Conference Paper)
We present optimum bit and power loading algorithms for orthogonal frequency division multiplexing (OFDM) systems using an M-ary quadrature amplitude modulation (M-QAM) scheme. Several scenarios for the amount of channel ...
A performance study of dual-hop transmissions with fixed gain relays
(
IEEE
, 2004 , Article)
This letter presents a study on the end-to-end performance of dual-hop wireless communication systems equipped with nonregenerative fixed gain relays and operating over flat Rayleigh-fading channels. More specifically, it ...
