Improved 3d-Fe Computational Method For Magnetostatic Field Problems Using Unconstrained Vector Potential
(
Qatar University
, 1996 , Article)
This paper introduces an improved three dimensional finite-element (3D-FE) computational approach for magnetostatic field problems using unconstrained magnetic vector potential (MVP) formulation in conjunction with hexahedral ...
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 ...
Correlation Of Vapor-Liquid Equilibrium Data For Binary Mixtures Containing One Polar Component By The Parameters From Group Contributions Equation Of State
(
Qatar University
, 1993 , Article)
Use of a quadratic mixing rule in the Parameters from Group Contributions Equation of State increases the range of compounds for which vapor-liquid equilibrium behavior can be satisfactorily correlated. This is demonstrated ...
Unsteady-State Interphase Diffusion
(
Qatar University
, 1993 , Article)
This study is concerned with the problem of unsteady interphase diffusion for multicomponent dilute solutions. An integral technique, based on an approximate boundary-layer approach is used. Results are in good agreement ...
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 ...
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 ...
Use Of Spreadsheets For Rainfall-Runoff Calculations
(
Qatar University
, 1996 , Article)
The nature of rainfall-runoff calculations necessitates the use of different
equations for calculating losses and several response functions to route the
effective rainfall hyetograph through the catchment. The ...
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 ...
Selection Of Optimized Fuzzy Rules For Process Control Systems: Using Genetic Algorithms
(
Qatar University
, 1996 , Article)
In this paper modeling, selection and optimization of fuzzy rules for multivariable feedback process control and decision making systems are developed and discussed. A general model for multivariable fuzzy rules is derived ...
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 ...
