Paraboloid Shell As Footing
(
Qatar University
, 1999 , Article)
A simplified method for the design of paraboloid shell footing base on the displacement of the shell's crown where the column axial load is transferred to the footing has been developed. A case study was presented to ...
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 ...
LQRr Real-Time Control For Plants With Variable Parameters
(
Qatar University
, 2002 , Article)
This paper deals with real-time optimal LQR control of plants that experience sudden changes in their parameters and states. The technique is based on real-time LQR control problem. Riccati equation is solved recursively ...
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 ...
Causes For Delays In Construction Projects In Kuwait
(
Qatar University
, 2002 , Article)
The paper presents a study based on a research that analyzes and ranks the causes of delays in building and housing type projects undertaken by governmental agencies in Kuwait. The study was based on a survey with the ...
The Effect Of Initial Temperature On Burning Velocity Of Methane, Propane, Lpg And Iso Butane - Air Mixtures
(
Qatar University
, 2001 , Article)
In present work, the burning velocity of a fuel - air mixtures varies with equivalence ratio, temperature and number of carbon atoms. Laminar flame speed have been measured experimentally inside a tube using the optical ...
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 ...
Multicriterion Optimization Approach For The Design Of Induction Motors
(
Qatar University
, 1999 , Article)
In most engineering design problems, trade offs are to be made among competing factors. This is obvious in the design of electric motors, when more than viewpoint is to be considered. In this paper the problem of induction ...
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 ...
