    • The Behavior Of Molasses As A Microbial Nutrient In The Absence Of Microbes 

      Khairy, M.; Al-Awad, Musaed N.; Al-Saddique, Mohammed; Al-Misned, Omar A.; Shebl, M. ( Qatar University , 2000 , Article)
      In this work the effect of molasses, as a bacterial nutrient, on the pH and surface tension of the aqueous phase, IFT, and phase behavior after one week contact time was studied at 60°C. The results have shown that the pH ...

    • Cognitive relaying in wireless sensor networks: Performance analysis and optimization 

      Elsaadany M.; Abdallah M.; Khattab T.; Khairy M.; Hasna , Mazen ( IEEE , 2010 , Conference Paper)
      The anticipated increase in the density of the deployed wireless sensor networks calls for spectrum sharing through unlicensed access to licensed spectrum. The key technology for spectrum sharing in this scenario is cognitive ...

    • Priority-based scheduling for limited energy cognitive relaying 

      Elsaadany M.; Khattab T.; Hasna , Mazen; Abdallah M.; Khairy M. ( IEEE , 2010 , Conference Paper)
      We study the problem of cognitive relaying with limited-energy constraint in opportunistic spectrum access cognitive networks. Under this network setting, the cognitive user increases the spectrum availability for its own ...
