Catalytic Oxidation Of Petroleum Waxy Distillates
(
Qatar University
, 1994 , Article)
The catalytic oxidation of petroleum waxy distillate (boiling range 400 - 440°C at 760 nun Hg) using KMn04 catalyst and air was studied in a batch reactor. The effect of reaction temperature (100-160°C), air flow rate ...
Concrete Deterioration And Repair In An Industrial Environment
(
Qatar University
, 1994 , Article)
This case study is concerned with concrete deterioration and its repair in an Industrial Plant (Qatar Petrochemical Company). Three different cases are identified according to the type and the environment of the structural ...
Numerical Study Of Magneto-Fluid-Mechanics Forced Convection Pipe Flow
(
Qatar University
, 1994 , Article)
The problem of fully developed, laminar, steady, forced convection heat transfer in an electrically conducting fluid flowing in an electrically insulated, horizontal, circular pipe (whose wall is subjected to a uniform ...
Correlations Of Some Tensile Properties For Various Grades Of Low Density Polyethylene
(
Qatar University
, 1994 , Article)
The tensile properties of nine different grades of low density polyethylene were measured, and the relationships resulting from the combination of different pairs of properties were analyzed. It was found that some properties ...
Nonlinear Adaptive Control Of A Permanent Magnet Stepper Motor
(
Qatar University
, 1994 , Article)
This paper considers adaptive position control of a permanent magnet (PM) stepper motor using exact linearization via static state-feedback. Physical outputs are chosen in such a way that the resulting closed-loop system ...
Flash Point For Binary Mixtures
(
Qatar University
, 1994 , Article)
Three flammable binary systems were studied for flash point as a function of liquid mixture composition: 1) decane/dodecane, 2) 0-xylene/cyclohexanol, and 3) 2-propanol/water. The vapor composition was estimated at each ...
Shear Behavior Of Reinforced High-Strength Concrete Beams Without Shear Reinforcement
(
Qatar University
, 1994 , Article)
Eighteen rectangular singly reinforced high-strength concrete beams without web reinforcement were tested in combined shear and flexure. The main variables were the longitudinal steel reinforcement ratio and the shear-span ...
Three Dimensional Analysis Of Space Imageries
(
Qatar University
, 1994 , Article)
Space imageries with their low costs and availability for every one, provide a
good opportunity for topographic mapping of unmapped or poorly mapped areas
around the world particularly in the developing countries.
The ...
Chebyshev Expansion Of The Flow In A Spinning And Coning Cylinder
(
Qatar University
, 1994 , Article)
This paper is concerned with the calculation of the moments exerted by a viscous fluid on the walls of a cylinder that is spinning about its axis and coning about an axis that passes through its center of mass. For small ...
Recognition Of Cursive Texts Using Hamming Neural Nets
(
Qatar University
, 1994 , Article)
Hamming Neural networks are employed for cursive text character separation and recognition. The digitized image of the scanned text is first enhanced by applying simple contrast stretching algorithm. Image registration is ...
