A new depositional model and sequence stratigraphic interpretation for the upper Jurassic Arab "D" reservoir in Qatar
(
Wiley online Library
, 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 ...
Formation of a cold antihydrogen beam in AEGIS for gravity measurements
(
AIP Publishing
, 2008 , Article)
The formation of the antihydrogen beam in the AEGIS experiment through the use of inhomogeneous electric fields is discussed and simulation results including the geometry of the apparatus and realistic hypothesis about the ...
On certain estimates for marcinkiewicz integrals and extrapolation
(
Universidad de Barcelona
, 2009 , Article)
We obtain Lp estimates for parametric Marcinkiewicz integrals associated to polynomial mappings and with rough kernels on the unit sphere as well as on the radial direction. These estimates will allow us to use an extrapolation ...

Risk assessment of accidental spills of toxic and flammable liquids on land
(
Emerald Publishing
, 2004 , Master Thesis)
The main objective of this paper is the assessment of the environmental impact due to accidental spills of toxic and flammable liquids on land. Different case studies of possible accidents in the State of Qatar were ...
Fuzzy Logic in neurosurgery: predicting poor outcomes after lumbar disk surgery in 501 consecutive patients
(
Elsevier
, 2009 , Article)
Background: Despite a lot of research into patient selection, a significant number of patients fail to benefit from surgery for symptomatic lumbar disk herniation. We have used Fuzzy Logic-based fuzzy inference system (FIS) ...
An Equatorial Pacific rain event: influence on the distribution of iron and hydrogen peroxide in surface waters
(
Elsevier
, 2001 , Article)
The wet deposition of iron and peroxides was monitored during an intense rain squall in the equatorial Pacific Ocean. Iron and hydrogen peroxide were determined at sea using adsorptive cathodic stripping voltammetry (ACSV) ...
Reproductive functions of progesterone
(
Middle East Fertility Society
, 2007 , Other)
Progesterone has a central role in reproduction, being involved in ovulation, implantation, and pregnancy. Associated with this is the involvement of progesterone in regulation of uterine function during the menstrual ...
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 ...
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 ...
