Unrelated Machines Scheduling With Machine Eligibility Restrictions
(
Qatar University
, 2002 , Article)
In this paper we present a new heuristic algorithm to minimize the makespan for scheduling jobs on unrelated parallel machines with machine eligibility
restrictions ( R^ I M .1 C^^). To the best of our knowledge, the ...

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, ...
Repetitive Control Based Pwm Inverter Dead-Time Compensation For Ac Servo Drive
(
Qatar University
, 2002 , Article)
AC servomotor speed or current controller based on PI control and/or optimal control, can not eliminate the cyclical fluctuations of speed or current when subject to periodic disturbances. However, repetitive control ...

Use Of Cement By-Pass Dust In Soil Stabilization
(
Qatar University
, 2001 , Article)
Cement by-pass dust (CBPD) or cement kiln dust (CKD) is a by-product of the manufacture of Portland cement. It is generated during the calcining process in the kiln. Lime (CaO) constitutes more than 60% of CBPD composition. ...

Comparing different methods for prediction of liquefied natural gas Densities
(
Qatar University
, 2005 , Article)
The densities of several liquefied natural gas (LNG) mixtures and pure methane using different equations of state and correlations have been predicted and compared with the experimental values. The equations of state were ...
Pyrolysis Kinetics of Oil-Palm Solid Waste
(
Qatar University
, 2005 , Article)
Pyrolysis of oil-palm shells, a cheap and abundantly available solid waste from palm oil producing process, was carried out using thermogravimetric analysis. The effect of heating rates (10,15,20 and 25°C/min) on the kinetic ...
