Construction Simulation Using Virtual Reality
( Qatar University , 1996 , Article)Two main simulation methodologies namely, the network-based simulation and the graphical simulation technique are being used in the construction industry. While the network-based simulation technique, which was originally ... -
Convection In A Rotating Fluid Over A Sloping Bottom, With Application To The Arabian Gulf
( Qatar University , 1992 , Article)Convective motions over a sloping bottom driven by evaporation and freshening are investigated by integrating the complete momentum and mass conservation equations. The problem is posed as an initial value problem in a ... -
Creep Buckling Of Plates Under Biaxial Compression
( Qatar University , 1992 , Article)This work presents an analysis for the creep buckling problem of geometrically imperfect rectangular flat plates under biaxial compression with simple support boundary conditions. The analysis is based on a non-dimensional ... -
Determination Of Rheological Properties Of Polymer Solutions In Sandpacks
( Qatar University , 1992 , Article)There is a correlation between mobility ratio and oil recovery by water displacement in homogeneous and heterogeneous reservoirs. Because of this correlation, it is essential to develop a mobility control process which ... -
Evaluation Of Corrosion Resistance Of A Duplex Stainless Steel "Ferralium" In Dead Sea Brine
( Qatar University , 1992 , Article)Corrosion behavior of Ferralium Alloy 255 during service in the environment of concentrated Dead Sea brine has been investigated. It was found that, the corrosion attack is intergranular and exists only in the weld heat ... -
Potential Use Of Carbide Lime Waste As An Alternative Material To Conventional Hydrated Lime Of Cement-Lime Mortars
( Qatar University , 1992 , Article)The present study aimed at the possibility of using the carbide lime waste as an alternative material to the conventional lime used for cement-lime mortar. The waste is a by-product obtained in the generation of acetylene ... -
Prediction Of Refrigerant Thermodynamic Properties By Equations Of State
( Qatar University , 1992 , Article)The ability of three equations of state (EOS) for calculating the thermodynamic properties of refrigerants has been studied for 35 pure component refrigerants. Three equations of state studied were the Soave-Redlich-Kwong ... -
Random Distributed Algorithms For Clock Synchronization
( Qatar University , 1992 , Article)This paper proposes clock synchronization algorithms based on the idea in which randomly chosen m out of the total N processors cooperate to perform the clock adjustment of all processors in a distributed system. Selection ... -
