Stability Of Square Interval Matrices For Discrete Time Systems
(
Qatar University
, 2001 , Article)
New sufficient conditions for the Schur stability of interval matrices are provided. Moreover, a time saving version of a necessary and sufficient condition for the Schur stability of a class of interval matrices is ...
Performance Of A Cool Thermal Store Filled With Balls Containing Water
(
Qatar University
, 2001 , Article)
A cool thermal storage (CTS) system can be integrated with an A/C system in order to reduce power consumption during a period of high demand. Investigator conducted experiments to investigate the performance of a CTS during ...
Finite Element Analysis Of Tubular Induction Accelerators
(
Qatar University
, 2001 , Article)
The paper develops a method of analyzing tubular induction accelerators based on the finite element technique. The method takes end effects (due to current discontinuities at the rotor edges) into consideration. The ...
Effect Of Production Induced Stresses On Reservoir Productivity
(
Qatar University
, 2001 , Article)
The importance of permeability sensitivity to the changes in pore pressure drop or effective overburden stress increase has been examined at laboratory using two types of rocks, sandstone and limestone. Whereas the ...
Performance Evaluation Of Biped Robot Optimal Gait Based On Genetic Algorithm
(
Qatar University
, 2001 , Article)
A Genetic Algorithm (GA) gait synthesis method for walking biped robots is considered in this paper. The walking occupy most of the time during the task performance, therefore its gait is analyzed based on the minimum ...
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 ...
Use Of Cement By-Pass Dust In Soil Stabilization
(
Qatar University
, 2001 , Article)
Cement by-pass dust (CBPD) or cement kiln dust (CKD) is a by-product of the manufacture of Portland cement. It is generated during the calcining process in the kiln. Lime (CaO) constitutes more than 60% of CBPD composition. ...
Contribution Of Horizontal Drilling Technology In The Development Programs Of Saudi Oil Fields
(
Qatar University
, 2001 , Article)
The technology of drilling and production of horizontal wells is probably one of the most significant breakthrough in the oil and gas industry of the eighties. The continuous improvement of hardware equipment made horizontal ...
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 ...
Effect Of Series Resistance On Photovoltaic Properties Of In-Doped Cdte(P) Thin Film Homojunction Structure
(
Qatar University
, 2001 , Article)
The photovoltaic properties of In-doped CdTe(p) thin film homojunction structure have been investigated, specially the effect of the series resistance on the short-circuit current at low and high light intensities has been ...
