Validation of CFD simulation for flat plate solar energy collector
(
Elsevier
, 2007 , Article)
The problem of flat plate solar energy collector with water flow is simulated and analyzed using computational fluid dynamics (CFD) software. The considered case includes the CFD modeling of solar irradiation and the modes ...
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 ...

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) ...
The effects of ion bombardment of ultra-high molecular weight polyethylene
(
Elsevier
, 2006 , Article)
Ion bombardment is a suitable tool to improve tribological properties of polymers. In this study UHMWPE samples were bombarded with 130keV He ions to the fluences ranging from 1×1014 to 2×1016cm−2. RBS and NRA techniques ...
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 ...
Temperature and electric field effects on the dielectric dispersion of modified polyvinyl chloride
(
Elsevier
, 2003 , Article)
The effect of electric field on the dielectric dispersion of modified polyvinyl chloride (PVC) has been investigated. The applied direct current (DC) field strength was ranging from 0 to 104 V cm−1. The complex permitivity ...
