Reproducing Formula and Algorithm of a Familv of Biorthonormal Wavelets
(
Qatar University
, 2005 , Article)
In this paper we present a family of biorthonormal wavelets generated by a MRA orthonormal wavelet, which possesses two arbitrary parameters. Then we discuss new expressions of reproducing kernel as well as the corresponding ...
p-cds/n-Si Anisotype Heterojunction solar cells wih Efficiency of 6.4%
(
Qatar University
, 2005 , Article)
In the present paper, p-CdS/n-Si heterojunction solar cells are prepared for the first time by the spray pyrolysis technique. Using such low-cost method, cells with 6.4'/o AM1 conversion efficiency ina O.ZZ fill factor ...
Investigation of Magnesium (II), Calcium (II) and Barium (II) Complexes in Aqueous Solution
(
Qatar University
, 2005 , Article)
The ionic association constants, K6, of Mg, Ca and Ba metal ions with succinate, malate and tartrate ligands were conduct metrically determined in water at 25-40°C. The conductometric data were analysed by the Shedlovsky ...
Experimental Investigation of the N-Pbs/P-Si Heterojunction Band Lineup with I-V and C-V Measurements
(
Qatar University
, 2005 , Article)
In this paper we present experimental investigation of band lineup of near ideal PbS/Si heterojunction diode using I-V and C-V measurements. The C-V measurements show that the fabricated diodes were abrupt type, and the ...

Macro-invertebrates from eleven stations along the Qatar Exclosive Economic Zone (EEZ), Arabian Gulf, were studied during December 1998. A total of 52 species were encountered from all stations. Crustaceans were the most ...
Possible Ionic Effects of NaCl on Two Mexican Wheat Cultivars
(
Qatar University
, 2005 , Article)
The effect of NaCl on growth and physiology of two Mexican wheat (Triticum asestivum L) cultivars (Cajeme: salt tolerant, and Yecora: salt sensitive) was compared with that of other osmotic agents, Na2SOa (ionic compound) ...
Evaluation of Electron Swarm Parameters in SF6 Using Monte Carlo Method
(
Qatar University
, 2005 , Article)
The motion of electrons in sulfur hexafluoride (SFo) in uniform electric fields is simulated using a Monte Carlo method. The swarm parameters are evaluated and compared with experimental results of drift velocity, electron ...
