Unsteady State Two Phase Flow Pressure Drop Calculations
(
Qatar University
, 1992 , Article)
A method is presented to calculate unsteady state two phase flow in a gas-liquid line based on a quasi-steady state approach. A computer program for numerical solution of this method was prepared. Results of calculations ...
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 ...
A Hadamard Transform Fuzzy Segmentation And Classification Technique For Image Compression
(
Qatar University
, 1996 , Article)
A new technique for image data compression based on fuzzy segmentation, classification and properties of sequency ordered Hadamard Transform (HT) is presented. Using a pyramidal data structure, an image is segmented into ...
Preliminary Design Of Reinforced Concrete Beams Using Neural Networks
(
Qatar University
, 2000 , Article)
This paper presents a backpropagation neural network model for the preliminary design of rectangular concrete beams. The model, which is developed based on the strength design procedure of the American Concrete Institute ...
Energy Study of A Gas-Fired Turbo-Generator
(
Qatar University
, 1988 , Article)
As far as energy utilization is concerned, the performance of a gas turbine-generator combination, depends on some key factors among which are; engine features, methods of utilizing heat energy associated with exhaust ...
Rainfall Characterization In An Arid Area
(
Qatar University
, 1991 , Article)
The objective of this work is to characterize the rainfall in Doha which lies in an arid region. The rainfall data included daily rainfall depth since 1962 and the hyetographs of the individual storms since 1976. The ...
Compressive And Tensile Strength Of Concrete Loaded And Soaked In Crude Oil
(
Qatar University
, 2000 , Article)
Effect of crude oil on compressive, splitting-tensile, and flexural-tensile strength of concrete under short-term and Lr.^-term loading, were investigated. Results show that the rate of crude oil absorption is high at early ...
Calcium Nitrite Effect On Setting Of Cement At Various Temperatures
(
Qatar University
, 2000 , Article)
Calcium Nitrite, which is used as corrosion inhibitor, accelerates stiffening rates of cement. This paper deals with the effect of calcium nitrate on setting times of cement pastes at various curing temperatures. Four ...
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 ...
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 ...
