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. ...
Laboratory-Scale Tests on Gas-Solid Fluidized Bed Behaviour And Its Influence on Bed Thermal Properties
(
Qatar University
, 1988 , Article)
The success of many industrial processes depends upon good contact between a fluid and particulate solid. A fluidized bed fulfils the requirements for this good contact. This paper presents the results of an experimental ...
Analysis of A Screen Type Solar Air Collector Without Transparent Cover
(
Qatar University
, 1989 , Article)
The performance of a screen type solar air collector of different uniform mesh sizes and without a glass cover is investigated theoretically. Formulation of simultaneous radiation and convection heat transfer for a semi-steady ...
Economic Analysis of Corrosion Control In Petroleum Refineries
(
Qatar University
, 1988 , Article)
Economic analysis of corrosion problems and their prevention or control was found to gain very little importance in the last 10 years according to the published work surveyed.
This article surveys the most important work ...

Corrosion Failures: Identification, Diagnosis & Remedies
(
Qatar University
, 1988 , Article)
This paper deals with the nature, typical surface features and common forms of corrosion. It also reports corrosion rates in various locations and under differing environmental conditions, viz. tropical, marine, urban and ...
On the Design of Bit-Slice Processors
(
Qatar University
, 1988 , Article)
In the past decade, fixed instruction microprocessors have evolved from 4 bits to 32 bits. Their compact design and relative low cost have made them very popular with design engineers. Their use extends into a lot of ...
Full Scale Performance of Primary Settling Tanks
(
Qatar University
, 1989 , Article)
The characteristics and the flowrate of municipal wastewater from the city of Doha, located in the Arabian Gulf have been studied to examine their effect on the performance of the primary settling tanks at the local sewage ...
Material Behaviour Under Corrosive Environment — Guide For Material Selection
(
Qatar University
, 1988 , Article)
In this paper, the behaviour of engineering materials as influenced by fluid velocity, operating temperature, humidity and duration of exposure to chemical and/or electro-chemical action is carefully studied, corrosive ...
