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 ... -
Refrigerants Beyond 1995 - An Overview
( Qatar University , 1994 , Article)The count down has started. Less than 400 days, that is all the time left till the complete phase-out of CFC production. No more refrigerants R-l 1, R-12 or R-500 will be produced worldwide. With our extreme dependence - ... -
Parallel Computing Applied To Compensate The Effect Of Amplifier Bandwidth In The Design Of Switched Capacitor Networks
( Qatar University , 1994 , Article)A method is described for the extraction of capacitor values for switched capacitor (SC) networks which compensate for the effect of finite amplifier bandwidth in the design of SC networks using optimization. The finite ... -
Hot Ductility Of Directly Cast Steels With Different Carbon Contents
( Qatar University , 1995 , Article)Tensile samples of Nb containing steels with different carbon contents have been cast in situ, cooled to test temperatures in the range 800-1000 °C and tested at a strain rate of 3x10 s . The austenite grain sizes of the ... -
Assessment Of Blending Local And Imported Aggregates On Properties Of Their Asphalt Concrete Mixtures
( Qatar University , 1995 , Article)Environmental conditions in the State of Qatar together with lack of good-quality aggregates seem to severely reduce the service lives of constructed pavements. The current practice of road construction agencies in Qatar ... -
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 ... -
On Improving Communication Software Development Process
( Qatar University , 1995 , Article)This paper aims to standardize the software development process by making use of the well-established hardware development process. The procedure can be applied to any engineering software development process, but we ... -
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 ... -
Cascaded Coding Schemes For Public-Key Cryptography
( Qatar University , 1995 , Article)1976 Diffic and Hellman introduced the concept of public-key cryptography and in 1978, McEliece introduced the first public-key cryptosystem based on error correcting codes. Since that time, several methods have been ... -
An Algorithm To Minimize Unused Lengths Of Steel Bars And Sections
( Qatar University , 1995 , Article)The reinforcement steel bars and other metal or wooden sections used in the construction industry are usually available in standard lengths and are cut in large numbers of specified lengths (pieces) according to the needs ... -
Simulation Of Three-Phase Distillation Column Using Bubble Point And Φ-Φ Approach
( Qatar University , 1995 , Article)Most of organic compounds are partially miscible in water and due to their solubility criteria split into two liquid phases. So design of equipments that separate two liquid phase systems differ from one liquid phase system ... -
Viscosity Of Hydrocarbon Liquids Saturated With Gas
( Qatar University , 1995 , Article)Experimentally measured kinematic viscosities are reported for benzene, cyclohexane and n-heptane saturated with hydrogen, nitrogen and carbon dioxide. A Zeitfuchs cross-arm viscometer suspended in a unique design ... -
Effective Moment Of Inertia And Deflections Of Reinforced Concrete Beams Under Long-Term Loading
( Qatar University , 1995 , Article)The paper presents a method for estimating long-term deflections of reinforced concrete beams by considering creep and shrinkage effects separately. Based on equilibrium and compatibility conditions a method is developed ... -
Measurement Of Thermal Conductivity Of Thermally Low-Conducting Materials
( Qatar University , 1995 , Article)The thermal conductivity of a building material is a necessary parameter in estimating the cooling load of a building. Cooling load estimates are quite important in selecting building materials especially in hot-climate ... -
Performance Evaluation Of Water Distribution Network Using Computer Model Simulation
( Qatar University , 1995 , Article)The paper describes the water supply system in Doha. It discusses the methodology used in estimating the water demand for each node of the water distribution network in the Garrafa District of Doha. A computer model of the ... -
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 ... -
