Optical properties of ultraphosphate glasses containing mixed divalent zinc and magnesium ions
(Elsevier, 2013-01)
Ternary zinc magnesium ultraphosphate glasses corresponding to (ZnO)x(MgO)30−x(P2O5)70 were prepared by melt quenching technique in the range of 5 ⩽ x ⩽ 20 mol%. The optical absorption spectra of the glasses were measured ...
The influence of human head model wearing metal-frame spectacles to the changes of SAR and antenna gain: Simulation of frontal face exposure
(EMW Publishing, 2013)
The relationship between specific absorption rate (SAR) and antenna gain inside the head due to the metal-frame spectacles was investigated. The radio frequency (RF) energy source considered is the smartphone used in the ...
The performance of two antenna design shapes in ultra-wideband wireless applications
(Asian Research Publishing Network (ARPN), 2014)
The extensive requirements for small Ultra wideband (UWB) communication systems lead to design active and
small size antennas. In this research two rectangular microstrip antennas were designed to cover the UWB ...
A novel approach evaluation for enhancing networks
(Elsevier B.V., 2013)
This study reveals for a creation of a system that has the ability to prove the technical feasibility and the advantages of a joint Radio Frequency and fiber optic system with self-trace directional control between deployed ...
Effect of lattice constant on band-gap energy and optimization and stabilization of high-temperature In xGa 1 -xN quantum-dot lasers
(Springer US, 2012-07)
We analyze the effect of the lattice constant on the band-gap energy of In x Ga1−x N and optimize the structure of the device with a separate-confinement heterostructure. To vary the lattice constants, we change the In ...
Energy monitoring based on human activity in the workplace
(Institute of Physics Publishing, 2014)
Human behavior is the most important factor in order to manage energy usage. Nowadays, smart house technology offers a better quality of life by introducing automated appliance control and assistive services. However, human ...
Application of InN based quantum dot in reducing short circuit current variation of solar cell above room temperature
(Trans Tech Publications, 2014-01)
This paper focuses on the applicability of InN based quantum dot in the active layer of the solar cell to reduce the short circuit current variation above the room temperature. We have investigated numerically the effect ...
Smart platforms surveillance system to enhance communication in disaster environments
(Engg Journals Publications, 2013-04)
The modern communications technology is a positive case for disaster risk reduction, since they to it provides critical information to realize risk assessment. In this study, we present an innovative technique is characterized ...
A cost-effective method for high-quality 60GHZ optical millimeter wave signal generation based on frequency quadrupling
(EMW Publishing, 2013)
In this paper, we present a cost effective method to generate a high-quality quadruple frequency optical millimeter- wave (MMW) signal using an integrated dual-parallel Mach-Zehnder modulator (IDP-MZM). Not only does the ...
Dual-band, parabolic, slotted ground plane-directive antenna for WLAN applications
(Taylor & Francis, 2013)
Wireless local area network (WLAN) is one of the common terms used by researchers in the communications area that allows wireless, long-range communication. Antennas are used as a medium of transmission, and in recent WLAN ...
