A Multi band mini printed omni directional antenna with v-shaped for RFID applications
(EMW Publishing, 2011)
This paper presents a mini multi-band printed omni-directional antenna with v-shaped structure for radio frequency identification (RFID) applications. The proposed multi-band antenna is developed from the initial v-shaped ...
The effect of silane treatment on processing characteristic and swelling behavior of polypropylene/recycled acrylonitrile butadiene rubber/rice husk powder composites
(Trans Tech Publications, 2011-03-22)
The effect of silane treatment on processing characteristic and swelling behavior of recycled acrylonitrile butadiene rubber (NBRr)/polypropylene (PP)/rice husk powder (RHP) composites has been studied. Polypropylene/recycled ...
Tensile properties of kenaf/unsaturated polyester composites filled with a montmorillonite filler
(Wiley Periodicals, Inc., 2011-03-05)
Kenaf/unsaturated polyester composites filled with montmorillonite (MMT) filler were produced. Overall, the study showed that, for samples with kenaf filler only, the strength properties decreased as the kenaf filler loading ...
Effect of excess mgo mole ratio in a stoichiometric cordierite (2MgO·2Al2O3·5SiO 2) composition on the phase transformation and crystallization behavior of magnesium aluminum silicate phases
(The American Ceramic Society, 2011-05)
The effect of excess MgO, 2.0-4.0 mol ratios on the crystallization behavior and purity of Iμ-cordierite was investigated using X-ray diffraction (XRD), differential thermal analyzer, and TGA. Quantitative XRD, the Rietveld ...

Investigated optical and elastic properties of Porous silicon: Theoretical study
(Elsevier Ltd., 2011-08)
Compatibility between experimental and theoretical works is achieved. Empirical Pseudopotential Method (EPM) is used to calculate the energy gap of Si which is found to be indirect. Features such as refractive index, optical ...
Effect of impurities content from minerals on phase transformation, densification and crystallization of α-cordierite glass-ceramic
(Elsevier B.V., 2011-07-14)
α-Cordierite glass-ceramic was produced through crystallization of glass compacts made of milled glass frits. A comparative investigation between two different initial raw materials to synthesize α-cordierite glass-ceramic ...
Aerodynamic study of combustor using axial swirler
(Praise Worthy Prize S.r.l., 2011-01)
A study has been conducted to investigate the flow pattern in a gas turbine combustion chamber by simulation and experimental approaches. Flow pattern inside a combustor is important to self sustain the flame, increase ...
Mechanical and thermal properties of chitosan-filled polypropylene composites: The effect of acrylic acid
(Society of Plastics Engineers, 2011-06)
The mechanical properties, morphology, and thermal properties of chitosan-filled polypropylene (PP) composites have been studied. The effect of the chemical modification of chitosan by acrylic acid treatment was also ...
Relationship between engine oil viscosity with age and temperature
(Universiti Kebangsaan Malaysia (UKM), 2011-05)
Single grade engine oil viscosity experience changes influenced by temperature and pressure. In reality however, the viscosity of the engine oil is also affected by age. A relationship between oil's viscosity with temperature ...
