Optical Matching For Microwave Active Devices
(
Qatar University
, 1997 , Article)
This paper describes a microstrip optically controlled matching technique between microwave active devices with low impedance (less than 10 ohms) and a conventional 50 or 70 ohm communication system in the upper microwave ...
Electrical Conductivity Of Aluminum Reinforced Graphite Electrodes
(
Qatar University
, 1993 , Article)
Composite, disc-like aluminum reinforced graphite electrodes were prepared, and an integrated parametric analysis has been performed to investigate the effect of some processing parameters on the electrical conductivity ...
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 ...
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 ...
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 ...
Drag On Non-Spherical Particles In Non-Newtonian Fluids
(
Qatar University
, 1996 , Article)
The drag coefficient (CD ) was determined for three different non-spherical
particles (cubes, rectangles and cylinders) of different sizes falling in two
different non-Newtonian fluids (glycerol and polymer - paraffin ...
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 ...
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 ...
A Case Study Of Traffic Characteristics And Proposed Improvement Schemes For An Arterial Road
(
Qatar University
, 1993 , Article)
This case study represents a typical example of surveying and assessing traffic characteristics along a local ring road in Doha City. Expected impacts of possible short-term (5-year) traffic management schemes for two main ...
