    • Viscosity Of Hydrocarbon Liquids Saturated With Gas 

      Al Harbi, Dulaihan K. ( Qatar University , 1995 , Article)
      Experimentally measured kinematic viscosities are reported for benzene, cyclohexane and n-heptane saturated with hydrogen, nitrogen and carbon dioxide. A Zeitfuchs cross-arm viscometer suspended in a unique design ...

    • The Voltage Collapse Problem Based On The Power System Loadability 

      Alammari, R. A. ( Qatar University , 1997 , Article)
      This paper addresses the problem of voltage instability at which the power system reaches its maximum admissible load. A voltage collapse proximity indicator (VCPI) is derived and its performance is investigated. The VCPI ...

    • Voltage Stability Margin Identification Using Local Measurements And Linear Kalman Filter 

      Alammari, R. A. ( Qatar University , 2002 , Article)
      Voltage stability investigation is of a great importance for long-term electric load expansion as well as power system operation. This paper presents a new algorithm for identification of voltage instability in a specified ...
