Effect Of Aspect Ratio On Torsional Capacity Of High-Strength Plain Concrete Deep Beams
(
Qatar University
, 1993 , Article)
Twenty high-strength plain concrete deep beams were tested under torsion. The variables were concrete strength and depth/width (aspect) ratio. Concrete strengths of 51.01, 58.53, 76.60 and 83.66 MPa and depth/width (aspect) ...
The Onset Of Resonance In Two-Immiscible Fluids Inside A Spinning And Coning Cylinder
(
Qatar University
, 1993 , Article)
Resonance of the motion of two fluids inside a cylinder that spins about its axis and rotates (cones) about an axis that passes through its center of mass is known to occur for low-viscosity fluids (high Reynolds number ...
Cone Penetration Testing For Field Density Prediction
(
Qatar University
, 1993 , Article)
This paper summarizes an experimental program for developing a pilot procedure to check and predict field densities of compacted soils using static cone penetration tests. Three sandy soils were tested. The testing program ...
Optimizing Use Of Marshall Asphalt Mix Design
(
Qatar University
, 1997 , Article)
Rutting has been a problem in Qatar's highway pavements since it began designing asphalt mixtures with the Marshall Method in the early 1990's. This paper describes specifications and rules-of-thumb which have been ...
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 ...
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 ...
Application Of Artificial Neural Networks To Predict Wettability And Relative Permeability Of Sandstone Rocks
(
Qatar University
, 1996 , Article)
An Artificial Neural Network (ANN) model based on the back-propagation technique is trained with a number of variables from experimentally established relative permeability curves. The reservoir core input data covers an ...
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 ...
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 ...
Liquid Density Of Pure And Multicomponent Fluids By Scaled-Variable-Reduced-Coordinate (Svrc) Method
(
Qatar University
, 1995 , Article)
The Scaled-Variable-Rcduced-Coordinatc (SVRC) method with a proposed set of mixing rules are applied to calculate the liquid density of several system of liquid mixture and satisfactory results are obtained. The ability ...
