Band allocation for cognitive radios with buffered primary and secondary users
El Shafie A.; Sultan A.; Khattab T. ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, we study band allocation of Ms buffered secondary users (SUs) to Mp orthogonal primary licensed bands, where each primary band is assigned to one primary user (PU). Each SU is assigned to one of the available ... -
Development of efficient formulation for the removal of iron sulphide scale in sour production wells
Mahmoud M.; Hussein I.A.; Sultan A.; Saad M.A.; Buijs W.; Vlugt T.J.H.... more authors ... less authors ( Wiley-Liss Inc. , 2018 , Article)Iron sulphide scale, which exists in different forms, is common in sour oil and gas production wells. Iron sulphide hard scales are difficult to remove with acids, requiring mechanical intervention or the replacement of ... -
Impact of Surfactant on the Retention of CO2 and Methane in Carbonate Reservoirs
Eliebid M.; Mahmoud M.; Hussein I.; Elkatatny S.; Shawabkeh R.; Sultan A.; Al-Marri M.J.... more authors ... less authors ( American Chemical Society , 2018 , Article)Enhanced gas recovery methods such as foamed CO2 are recommended for depleted gas reservoirs. Viscoelastic surfactant (VES) is a form of a surfactant used for forming CO2 foam. In this study, the impact of VES on CH4 and ... -
Precious metal free Ni/Cu/Mo trimetallic nanocomposite supported on multi-walled carbon nanotubes as highly efficient and durable anode-catalyst for alkaline direct methanol fuel cells
Nazal M.K.; Olakunle O.S.; Al-Ahmed A.; Merzougui B.; Abualkibash A.; Sultan A.; Yousaf A.B.; Zaidi S.J.... more authors ... less authors ( Elsevier B.V. , 2018 , Article)Direct methanol fuel cells (DMFCs) proved to be an auspicious choice in the applications of portable power electronics and energy transportation, apart from their high cost catalysts materials. To this end, we have developed ... -
Screening of surfactants and polymers for high temperature high salinity carbonate reservoirs
Kamal M.S.; Sultan A.; Hussein I.; Hussain S.M.S.; AlSofi A.M. ( Society of Petroleum Engineers , 2018 , Conference Paper)Carbonate reservoirs typically exhibit significant heterogeneity, high temperature and high salinit ies. Surfactant and polymer selection for such reservoirs is a challenging process where extensive laboratory investigations ... -
Thermochemical Upgrading of Calcium Bentonite for Drilling Fluid Applications
Magzoub M.; Mahmoud M.; Nasser M.; Hussein I.; Elkatatny S.; Sultan A.... more authors ... less authors ( American Society of Mechanical Engineers (ASME) , 2019 , Article)The rheological properties of bentonite suspensions depend on the chemical composition and the contained dominant element, such as calcium (Ca), potassium (K), and sodium (Na). Na-bentonite type is the one used in drilling ...
