Study of the influence of xylene-based chemical Additive on crude oil flow properties and Paraffin deposition inhibition
(
Qatar University
, 2005 , Article)
Paraffin related problem appears through out the production process of nearly all kinds of crude oils all over the world. It also appears in the dewatering process and the long distance crude oil transportation. In Nigeria, ...
Signal Identification Using A Microprocessor Based Phase Locked Loop System
(
Qatar University
, 1989 , Article)
A scheme for waveform comparison and the measurement of periodic signal parameters through processing, controlling and measuring programs is realised. A microcomputer is used with a phase locked loop voltage controlled ...
Simulation of Cross-Current Extraction Processes
(
Qatar University
, 1988 , Article)
Extraction processes dealing with partially miscible solvents are usually calculated by graphical methods to estimate the number of stages required, flow rates and compositions of the streams. Such procedures may be lengthy. ...
A Computer Aided Design Tool For Area Optimization Using Breadth First Search Technique
(
Qatar University
, 1991 , Article)
Floorplanning is the process of partitioning an area on any surface such that the partitions guarantee minimum wasted area. The technique used to partition a given are depends on the requirements of the application. In an ...
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 Review of Fatigue Testing Machines
(
Qatar University
, 1990 , Article)
In this paper fatigue testing facilities are first classified in accordance with a number of features which include purpose, type of loading, method of load application and transmittal as well as control system.

Creep Buckling Of Plates Under Biaxial Compression
(
Qatar University
, 1992 , Article)
This work presents an analysis for the creep buckling problem of geometrically imperfect rectangular flat plates under biaxial compression with simple support boundary conditions. The analysis is based on a non-dimensional ...
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 ...
Effect Of Drilling Fluids Contaminations On Saudi Reservoir Rock Wettability
(
Qatar University
, 1998 , Article)
Wettability is a key parameter that affects the petrophysical properties of reservoir rocks. Mud nitrate during drilling pay zone causes a significant change in rock wettability that will affect the oil production and ...
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 ...
