Re-emission of slow positrons from tungsten at elevated temperatures
(
Elsevier
, 2002 , Conference Paper)
A series of measurements have been made on the dependence of the intensity and energy spectrum of slow positrons re-emitted from polycrystalline tungsten foil held at temperatures of up to 500 °C. Irrespective of target ...
Baseline formation for damage diagnosis in one dimensional-beam problems
(2002 , Conference Paper)
A brief account of the theories behind modal analysis, dimensional analysis, the stereolithography process and the strain energy damage detection method is presented. An integrated system of those techniques is formulated ...

(
Sultan Qaboos University
, 2002 , Article)
Well-exposed, fine-grained to pebbly coarse-grained fluvial sandstones of Late Miocene to Pleistocene age crop out in the south-central and south-western parts of Qatar. These sandstones belong to the Hofuf Formation and ...
Tests of a diamond field-assisted positron moderator
(
Elsevier
, 2002 , Conference Paper)
Diagnostic studies have been performed on a 70 μm thick diamond film with a view to its development as a possible field-assisted moderator (FAM) for slow positron emission. The film was coated on one side with a 200 nm ...

During a comprehensive survey carried out on helminth parasites of Arabian Gulf fishes mainly from the coasts of the Emirates and Qatar, two microsporeans and three myxosporeans Protozoa were reported and described for the ...
Fuzzy system applications for identification of weak buses in power systems
(
King Fahd University of Petroleum and Minerals
, 2002 , Article)
In this paper a simple new algorit hm for identifying the weak buses in a power system for voltage stability study is presented. The proposed algorithm is based on fuzzy set theory. Two membership functions, one for voltage ...
