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 ...
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 ...
Analysis Of The Coupling Gap Between Microstrip Antennas
(
Qatar University
, 1997 , Article)
The accurate and efficient Galerkin's method was developed in the spectral domain for analyzing gap discontinuities in patch antenna array. Using new current distribution the problem is solved using full wave approach ...
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 ...
The Voltage Collapse Problem Based On The Power System Loadability
(
Qatar University
, 1997 , Article)
This paper addresses the problem of voltage instability at which the power system reaches its maximum admissible load. A voltage collapse proximity indicator (VCPI) is derived and its performance is investigated. The VCPI ...
Amorphous Phase Properties Of Oriented Polyethylene Solids
(
Qatar University
, 1993 , Article)
Solid-state deformation of polyethylene results in a preferential orientation of both crystalline and amorphous regions. Usually, one major problem in the prediction of the mechanical and thermal expansion properties of ...
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 ...
Properties Of The Omani Sarooj
(
Qatar University
, 1997 , Article)
The fundamental properties of the Omani sarooj have been studied. Sarooj samples were collected from different sites to assess their pozzolanic activity. A laboratory testing program covering chemical and physical ...
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 ...
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 ...
