Experimental Measurement Of Drop Phase Mass Transfer Coefficients For The Carbon Tetrachloride-Acetic Acid-Water System
(
Qatar University
, 1991 , Article)
The overall mass transfer coefficients of single drops of carbon tetrachloride falling in a stagnant continuous phase of water containing acetic acid as solute were measured experimentally for different dispersed phase ...
Amorphous Phase Properties Of Oriented Polyethylene Solids
(
Qatar University
, 1993 , Article)
Solid-state deformation of polyethylene results in a preferential orientation of both crystalline and amorphous regions. Usually, one major problem in the prediction of the mechanical and thermal expansion properties of ...
A Self-Organizing Multisensor Fusion Classification Algorithm
(
Qatar University
, 1996 , Article)
A self-organizing multisensor fusion algorithm to classify the inputs (data or images) into classes (targets, backgrounds) is presented. The algorithm forms clusters and is trained without supervision. The clustering is ...
A New Technique To Predict Multilayered Reservoir Characteristics Using Pulse Testing Data
(
Qatar University
, 1998 , Article)
In this study, a mathematical model was developed to present pulse and interference testing for multilayered reservoirs. It was found that apparent storage calculated from pulse testing data is always less than or equal ...
How Top-Size Affects The Resilient Modulus Of Roadway Base Materials
(
Qatar University
, 1995 , Article)
The American Association of State Highway and Transportation Officials
(AASHTO) uses resilient modulus values as the load-carrying capacity parameter
for all pavement materials. However, the maximum sample diameter in ...
Design Of A Simple Apparatus For Reaction Kinetics And Reactor Design Experiments
(
Qatar University
, 1990 , Article)
Tubular reactor experiments arc an integral part of an undergraduate course in reaction kinetics and reactor design. However, the successful design of such experiments necessitates meeting a set of criteria regarding safety, ...
On The Computational Efficiency Of Four Numerical Techniques For Solving The Practical Inverse Kinematics Problem Of Redundant Manipulators
(
Qatar University
, 1990 , Article)
In this paper we compare the computational efficiency of four methods for solving the practical inverse kinematics problem of redundant manipulators. Two methods use recursive approaches for sequential determination of ...
A Comparison Between Artificial Neural Network And A Geostatistical Technique In The Estimation Of Regionalized Variables
(
Qatar University
, 1999 , Article)
In all mining estimation techniques data play a very important role. Insufficient data would mean the quality of the estimate is unreliable. Due to the importance attached to a good and representative data set, the application ...
Ultrasonic Pulse Velocity Versus Strength For Concrete In Qatar
(
Qatar University
, 1992 , Article)
Compressive strength of concrete is widely accepted as a characteristic property indicating and representing its quality. The accuracy of both ultrasonic and mechanical strength is discussed and the advantages of ultrasonic ...
Spreadsheet Class Scheduling For The College Of Engineering, University Of Qatar
(
Qatar University
, 1998 , Article)
The process of preparing class schedules is a lengthy and painstaking experience, especially when the requirements on the system approach saturation capacity. Instructors have to be assigned to places, with different ...
