Flow and Fracture Behaviour of Tungsten Fiber Reinforced Superalloy Composites-Effect Of Specimen Geometry
(
Qatar University
, 1989 , Article)
The influence of aspect ratio (i.e. width to height ratio) of test specimens on the flow and fracture behaviour of fiber reinforced composites is herein examined. The composite material was prepared by isostatic pressing ...
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 ...
Cone Penetration Testing For Field Density Prediction
(
Qatar University
, 1993 , Article)
This paper summarizes an experimental program for developing a pilot procedure to check and predict field densities of compacted soils using static cone penetration tests. Three sandy soils were tested. The testing program ...
High Frequency Characteristics Of Ferrite Materials And Applications To Microstrip Circuits
(
Qatar University
, 1999 , Article)
Dispersion behavior of the parameters of microstrip lines printed on ferrite substrate is presented. The characteristic impedance for lines on magnetized ferrite substrates are obtained for partially magnetized substrates ...
Experimental And Modeling Of Friables And Stone Oil Reservoirs Consolidation Using Steel Making Slag
(
Qatar University
, 2001 , Article)
A mathematical model was developed simulating the process of sand production in under downhole stress state. The model was derived based on Mohr-Colomb failure criterion, Darcy equation for radial flow and reservoir stress ...
Effect Of Aspect Ratio On Torsional Capacity Of High-Strength Plain Concrete Deep Beams
(
Qatar University
, 1993 , Article)
Twenty high-strength plain concrete deep beams were tested under torsion. The variables were concrete strength and depth/width (aspect) ratio. Concrete strengths of 51.01, 58.53, 76.60 and 83.66 MPa and depth/width (aspect) ...
Unrelated Machines Scheduling With Machine Eligibility Restrictions
(
Qatar University
, 2002 , Article)
In this paper we present a new heuristic algorithm to minimize the makespan for scheduling jobs on unrelated parallel machines with machine eligibility
restrictions ( R^ I M .1 C^^). To the best of our knowledge, the ...
Structural Design Of Arch Profile And Depth — A Computer-Aided Study
(
Qatar University
, 1991 , Article)
This paper presents a comparative study of some of the best known and widely used arch profiles, in an endeavour to investigating their structural performance and to determining optimum arch form and depth.
Arch profiles ...
Application Of Artificial Neural Networks To Predict Wettability And Relative Permeability Of Sandstone Rocks
(
Qatar University
, 1996 , Article)
An Artificial Neural Network (ANN) model based on the back-propagation technique is trained with a number of variables from experimentally established relative permeability curves. The reservoir core input data covers an ...
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 ...
