Research ArticleOpen accessIn the abstractSTRUCTURAL AND OPTICAL STUDIES OF CONDUCTING PANI/CuS NANOCOMPOSITES ON NANOCRYSTALLINE ZINC-OXIDE THIN FILMM. A. Sangamesha, K. Pushpalatha, G. L. ShekarIn this article, a p-n heterostructure diode was developed by incorporating the synthesised nanocomposite of CuS/PANI into the hallow network of ZnO thin film deposited on the glass substrate, which hitherto not reported. Analyses of the obtained heterostructure were carried out using XRD, FT-IR, UV-Visible and SEM. The penetration, bonding and the interaction of the nanocomposite with ZnO was investigated … …Current Research in Nanotechnology, Vol. 5, Issue 1 · 15 Aug 2014 · 7,044 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost-Effective Wire-Harness Model by Using Polymer Optical FiberMohammad Syuhaimi Ab-Rahman, Farshad Nasimi KhamenehIn the past decade automotive industries faced the exponential increase of in-vehicle electronic devices. The hydraulic systems are replacing with sophisticate electronic systems. Market demands for exploiting new in-vehicle technologies such as multimedia systems, internet access, GPS, Mobile communication, internal private network; engine, body and power train intelligent control and monitoring systems are increasing daily. These new needs make the … …Journal of Computer Science, Vol. 9, Issue 7 · 25 Jun 2013 · 7,021 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Doping Position on the Active Silicon-on-Insulator Micro-Ring Resonator Based on Free Carrier InjectionB. Mardiana, Sahbuddin Shaari, P. Susthitha Menon et al.Problem statement: Metal interconnects have become significant limitation on the scaling of CMOS technologies in electronics integrated circuit. Silicon photonics has offers great potential to overcome this critical bottleneck due to the advantages of optical interconnects. Silicon-based optical micro-ring resonator is promising basic element of future electronic-photonic integrated circuits because of its wide applications on photonic devices such as modulator, … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 9 Aug 2012 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntubation using the Video LaryngoscopeBen H. Boedeker, W. Bosseau Murray, Thomas A. NicholasProblem statement: Inadequate airway management is a major contributor to morbidity and mortality in the prehospital and out-of-operating room hospital settings. Difficulties that occur during airway management are usually related to the intubator not being able to achieve an adequate view of the glottic opening to allow insertion of an endotracheal tube. Approach: Obtaining an adequate glottic view is technically … …Current Research in Medicine, Vol. 3, Issue 2 · 3 Apr 2012 · 7,527 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Optical Splitter Design for Application in Fibre-to-the Home Passive Optical Network using Virtual Lab PlatformMohd Syuhaimi Ab-Rahman, Ainon Najahah Abdul Aziz, Aimi Amalin Khairuddin et al.Problem statement: In this study, authors present a new design of optical splitter to be applied in FTTH-PON named Multi Ratio Optical Splitter (MROS). MROS was introduced to enhance the power distribution in the optical network. Approach: We also bring in new approach for designing a new optical device that enable us to characterize and analyze the design from waveguide … …Journal of Computer Science, Vol. 8, Issue 6 · 16 Mar 2012 · 7,053 accessesView PDFCite
Research ArticleOpen accessIn the abstractTemperature Effect on Uncooled Semiconductor Laser Diode to the Network Performance SystemMohammad Syuhaimi Ab-Rahman, Nurain Izzati ShuhaimiProblem statement: The characteristics of a laser diode are highly dependent on the temperature of the laser chip. Thus, the effect of temperature on the network performance of uncooled semiconductor laser diode are studied by simulating its equivalent electrical circuit, developed from the rate equations that governing optical components directly into an electrical simulation framework. Approach: The simulations are carried … …Journal of Computer Science, Vol. 8, Issue 4 · 8 Feb 2012 · 6,621 accessesView PDFCite
