Research ArticleOpen accessIn the abstractA 2-12 GHz Low Noise Amplifier Design for Ultra Wide Band ApplicationsV. Vaithianathan, J. Raja, R. SrinivasanProblem statement: The Low Noise Amplifier (LNA) is a core block of an Ultra Wide Band (UWB) receiver since it amplifies a very weak signal received at the antenna to acceptable levels while introducing less self-generated noise and distortions. The LNA design poses a unique challenge as it requires simultaneous optimization of various performance parameters like power gain, input matching, … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 9 Jun 2012 · 7,397 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 abstractPerformance Analysis and Components Irreversiblities of a (25 MW) Gas Turbine Power Plant Modeled with a Spray CoolerFidelis Ibiang Abam, Ikpi U. Ugot, Dodeye Ina IgbongIn this study the effect of inlet air cooling system and components irreversibilities on the performance of an active 25MW gas turbine power plant was investigated. The objective of this study was to establish the potential benefits of improving the performance of the current gas turbine plant into a more advanced cycle with high efficiency and power output through inlet … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 24 Feb 2012 · 9,379 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of E100 to Fuel a Used 4-Stroke MotorcycleT. SuthisripokProblem statement: Though ethanol and gasohol are proved to be used as alternative fuels in vehicles, 4-stoke motorcycles used nationwide mainly consumed gasoline 91/95. Approach: The motorcycle tested, the used Honda Wave125 model, was properly tuned at the rich relative air-fuel ratio (λ) 0.85, which theoretically gave the maximum power output. For the use of E100, the engine required richer … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 23 Feb 2012 · 9,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractThird Order of Automatic Restoration Scheme Offered in Fiber ToThe Home-Passive Optical Network through Customer Access Protection UnitMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran JumariProblem statement: This study highlight on restoration scheme proposed against failure in working line at the drop region for Fiber To The Home (FTTH) with a Passive Optical Network (PON).

Research ArticleOpen accessIn the abstractDesign and Simulation of a Soft Switched Dc Boost Converter for Switched Reluctance MotorX. Felix Joseph, S. Pushpa KumarProblem statement: This study presents the design and simulation of a soft switched boost converter for a switched reluctance motor with a closed loop controller. A soft switching scheme is proposed in the converter with minimum components, which reduces the switching loss and stress across the switch so that the harmonic generation is reduced in the output. The switch used … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 2 Feb 2012 · 7,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow-Loss Hand-Made Demultiplexer using Transparent Color Filter in WDM-POF Network for Short-Haul Communication SystemMohd Syuhaimi Ab. Rahman, L. S. Supian, Hadi Guna et al.Problem statement: Polymer optical fiber has advantages compared to other alternatives communication media such as copper, coax cable and glass fiber. POF has bigger bandwidth compared to wireless communication network and POF is also free from electromagnetic disruption. Since POF is suitable for communication system up to distance of 100 m with data speed of 400 Mbps using polymer step-index … …Journal of Computer Science, Vol. 8, Issue 4 · 30 Jan 2012 · 7,087 accessesView PDFCite
