A novel square-spiral strip antenna
A square-spiral strip antenna is designed considering the procedure used to obtain log-periodic antennas. Simulation results of the new design are compared with those of the well known and widely used Archimedean spiral ...
Effect of aluminum closed-cell foam filling on the quasi-static axial crush performance of glass fiber reinforced polyester composite and aluminum/composite hybrid tubes
The effect of Al closed-cell foam filling on the quasi-static crushing behavior of an E-glass woven fabric polyester composite tube and thin-walled Al/polyester composite hybrid tube was experimentally investigated. For ...
Taylor series approximation of semi-blind BLUE channel estimates with applications to DTV
(Taylor & Francis, 2008-01)
We present a low-complexity method for approximating the semi-blind best linear unbiased estimate (BLUE) of a channel impulse response (CIR) vector for a communication system, which utilizes a periodically transmitted ...
Mechanical and thermal behavior of non-crimp glass fiber reinforced layered clay/epoxy nanocomposites
Mechanical and thermal properties of non-crimp glass fiber reinforced clay/epoxy nanocomposites were investigated. Clay/epoxy nanocomposite systems were prepared to use as the matrix material for composite laminates. X-ray ...

Satellite networks for key management
The cryptographic key management center is the place where all the cryptographical protocols and related keys are in action. Traditionally the key management centers operate on the ground. However; with the satellites, it ...
Identification and bioactivity of native strains of Bacillus thuringiensis from grain-related habitats in Turkey
A native collection of Bacillus thuringiensis (Bt) strains originated from grain-related habitats in Turkey was characterized according to serotype, cry1 gene content, and bioactivity against Ephestia kuehniella (Lepidoptera: ...
Supercritical deposition of Pt on SnO2-coated Al2O3 foams: Phase behaviour and catalytic performance
Deposition and reduction of an organometallic platinum complex from a supercritical Pt(COD)Me2/CO2 solution was carried out to produce Pt/SnO2 catalysts supported on Al2O3 foams for CO oxidation at moderate temperatures. ...
Adsorption of anionic polyelectrolyte and comb polymers onto lead magnesium niobate
This paper presents the results concerning the adsorption mechanism of polyacrylic acid (PAA) and polyacrylic acid/polyethylene oxide (PAA/PEO) comb polymer onto lead magnesium niobate (PMN) powders. In the study adsorption ...
Development of Si-O-C based ceramic matrix composites produced via pyrolysis of a polysiloxane
(Trans Tech Publications, 2004)
Pyrolytic conversion of a preceramic polymer, poly(phenyl)siloxane has been investigated to develop ceramic matrix composites (CMCs) at low temperatures with high dimensional stability. Furthermore, the thermal transformation ...
