, 2001 , Article)
Four Hemiurids collected from some marine fishes caught off Qatari waters int he Arabian Gulf are described and compared with related species previously reported from the Arabian Gulf and the Indian Ocean. These include ...
Frequency and harmonics evaluation in power networks using fuzzy regression technique
(
IEEE Computer Society
, 2001 , Conference Paper)
A new technique for frequency and harmonic evaluation in power networks is proposed in this paper. This technique is based on fuzzy linear regression and uses the digitized voltage samples, which are fuzzy numbers, to ...
Microstructure of heat-treated steel probed by positron annihilation
(2001 , Conference Paper)
Positron annihilation lifetime technique has been applied to study the microstructure change in steel after heat treatment. For this purpose, the specimens are heat treated in various manners; normalizing, annealing, ...
On the application of αβ-transformation for power systems frequency relaying
(
Institute of Electrical and Electronics Engineers Inc.
, 2001 , Conference Paper)
This paper presents a new and very accurate algorithm for power system frequency measurement. The proposed algorithm is based on αβ-transformation of the three phase voltages or current waveforms in the relay location, ...
Effects of harmonic distortion on the active and reactive power measurements in the time domain: A single phase system
(
IEEE Computer Society
, 2001 , Conference Paper)
A new application of the least error squares (LES) estimation algorithm is given for identifying, in the time domain, the active and reactive power from available samples of voltage and current waveforms. The digital ...

لا شك أن نسيان الإنسان لبعض الغيب الماضي من صالحه في دنياه وأخراه، فهناك العداوات والمظالم التي وقعت بين الأصول، وبين الدول والقبائل والشعوب، لو لم تطو صحائها، وتندثر معالمها، ولو لم تنس في بطون التاريخ وغابر الأزمان لكانت ...
Viscous-Gravity spreading of oil on water
(
John Wiley & Sons, Inc.
, 2001 , Article)
Spreading of oil on calm water is analyzed for the second stage of spread, which is controlled by a balance between gravity and viscous forces. The analysis, using the integral boundary-layer method, agreed well with a ...

(
Blackwell Publishing Ltd
, 2001 , Article)
Deposition of the Arab Formation on the Arabian Plate followed a eustatic sea-level high during the Oxfordian that deposited the open-marine shelfal carbonates of the Hanifa and Jubaila Formations. Oolite/peloidal shoals ...
مظاهر التجديد في فكر مالك بن نبي
(
جمعية المسلم المعاصر
, 2001 , Article)
الخلاصة : أن فكر مالك بن نبي يمثل ثقافة مزدوجة عالمیة : إسلامیة وغربیة ، وبحكم سعة أفقه وعمق تفكیره وثبات عقیدته ، استطاع أن يستقرئ الواقع الإسلامي ، ويكشف عن حالة تشتته ، ومن ثم طرح رؤيته فیما شكل حلاً لمشكلة الركود أو ...
