Reduction kinetics of ceria surface by hydrogen
(
Elsevier
, 2004 , Article)
Sintered ceria pellets of porosity 16.4% and density 5.99gcm−3 were treated in a hydrogen flow at 1atm and various temperatures. The electrical conductivity was measured in situ while hydrogen gas was flowing over the CeO2. ...
Surface layer modification of ion bombarded HDPE
(
Elsevier
, 2004 , Article)
Press-moulded, high density polyethylene (HDPE) samples were subjected to ion bombardment and effects of the modification studied. He+ ions of energy 100 keV or Ar+ ions of energy 130 keV were applied in the range of dose ...
Stability of membrane fouling particles under perikinetic and orthokinetic flow conditions
(
Elsevier B.V.
, 2004 , Article)
Stability of fouling particles against Brownian motion (perikinetic) and simple shear flow (orthokinetic) was investigated. The effect of the various parameters such as particle radius, Hamaker constant, salt (1-1 type) ...

(2004 , Article)
Fatty acids and lipids composition of fifty one species growing in Qatar belonging to twenty one families and forty three genera are reported
Long-term electric peak load forecasting for power system planning: A comparative study
(
King Fahd University of Petroleum and Minerals
, 2004 , Article)
A comparative study between two static estimation algorithms, namely least error squares (LES) and least absolute value (LAV) algorithm was presented. The proposed algorithm used the past history data for the load and the ...
Modeling, simulation and control of a scheibel liquid–liquid contactor: Part 2. Model-based control synthesis and design
(
Elsevier B.V.
, 2004 , Article)
This study describes an application of model-based control techniques to a liquid–liquid extraction process. The control design is based on a reduced order model of the process obtained by system identification. A multi-loop ...
Performance enhancement of relay-assisted communications via binary feedback
(
IEEE
, 2004 , Conference Paper)
This paper proposes a modified two-hop wireless communication system and studies its performance. The modified system has a reliable feedback channel that carries a binary signal from the receiver to inform the transmitter ...
Design and Assembly of Miniature Zirconia Oxygen Sensors
(
IEEE
, 2004 , Article)
Zirconia oxygen sensors are highly selective solid-state devices used for many applications, including combustion control for better fuel economy and lower emissions. Stabilized zirconia electrolyte meets the device ...
Integrating hybrid systems with existing thermal desalinationplants
(
Elsevier B.V.
, 2004 , Article)
In Gulf countries, most power plants are co-generation power desalting plants (CPDP) that generate electric energy and also produce fresh water through the desalination of seawater. This paper provides detailed technical ...
