A Model For A Narrow-Cut Fractionating Column
(
Qatar University
, 1997 , Article)
A mathematical model was developed to simulate the operation of a narrow-cut fractionating column. The model can calculate boiling point and dew point on the feed plate, the number of liquid and vapour moles, the enthalpy ...

(
Qatar University
, 1997 , Article)
Ultrasonic pulse-echo technique, tensile testing and thermal gravimetric analysis have been utilised to characterise and monitor the effect of y irradiation on the physicomechanical properties of low density polyethylene ...
Optimizing Use Of Marshall Asphalt Mix Design
(
Qatar University
, 1997 , Article)
Rutting has been a problem in Qatar's highway pavements since it began designing asphalt mixtures with the Marshall Method in the early 1990's. This paper describes specifications and rules-of-thumb which have been ...
Optical Matching For Microwave Active Devices
(
Qatar University
, 1997 , Article)
This paper describes a microstrip optically controlled matching technique between microwave active devices with low impedance (less than 10 ohms) and a conventional 50 or 70 ohm communication system in the upper microwave ...
The Voltage Collapse Problem Based On The Power System Loadability
(
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 ...
Analysis Of The Coupling Gap Between Microstrip Antennas
(
Qatar University
, 1997 , Article)
The accurate and efficient Galerkin's method was developed in the spectral domain for analyzing gap discontinuities in patch antenna array. Using new current distribution the problem is solved using full wave approach ...
Properties Of The Omani Sarooj
(
Qatar University
, 1997 , Article)
The fundamental properties of the Omani sarooj have been studied. Sarooj samples were collected from different sites to assess their pozzolanic activity. A laboratory testing program covering chemical and physical ...
Simplified Method For Plate Deflection Calculation
(
Qatar University
, 1997 , Article)
This paper presents a simplified method for the calculation of thin-plate deflections. The method, which deals with uniformly loaded plates, uses the stiffness method to obtain plate deflection equations for specified ...
