Research ArticleOpen accessIn the abstractHardware Implementation of Truncated Multipliers Using Spartan-3AN, Virtex-4 and Virtex-5 FPGA DevicesMuhammad H. RaisProblem statement: The development cost for Application Specific Integrated Circuits (ASICs) are high, algorithms should be verified and optimized before implementation. The Digital Signal Processing (DSP), image processing and multimedia requires extensive use of multiplication. The truncated multipliers can easily be implemented using Field Programmable Gate Array (FPGA) devices. Approach: This research presented the comparative study of Spartan-3AN, Virtex-4 and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,338 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Airflow and Aerodynamic Forces Acting on a Rotating Turbine VentilatorA.S. Farahani, N.M. Adam, M.K.A. AriffinProblem statement: Rotating turbine ventilators were generally found in most countries. They were simple in structure, light in weight and cheap to install. It was quite surprising that, the aerodynamics of this common device had not been numerically examined and the design process of most of these ventilators had developed progressively through trial and error methods. Approach: This study was … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Carbon Steel Pipe Protection Based on Radial Basis Function Neural NetworkSami Abulnoun AjeelProblem statement: The cost due to corrosion Damage have estimated to be 3-4% of their gross national product which significantly Countries problem around the world. Approach: In this study, a novel carbon steel pipe protection based on RBFNN was proposed. The RBFNN used to predict the minimum current density required in impressed current cathodic protection to protect low carbon steel … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 7,144 accessesView PDFCite
Research ArticleOpen accessIn the abstractIndoor Characterisation using High-Resolution Signal Processing Based on Five-Port Techniques for Signal Input Multiple Output SystemsSmari Mouheddin, Bel hadj Taher JamelProblem statement: The development of wideband mobile communication systems requires a deep knowledge of the characteristics of the indoor mobile radio channel. The characterization of the indoor multi-path propagation structure is important in developing antifading techniques for high-speed digital radio access. The high-resolution of the estimation of the Time of Arrival (ToA) and the Direction of Arrival (DoA) of multi-path … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,689 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal-Mechanical Analysis of a Different Leadframe Thickness of Semiconductor Package under the Reflow ProcessS. Abdullah, M. F. Abdullah, A. K. Ariffin, A. JalarThe copper-based leadframe is practically proven effective in the thermal and reliability of a Quad Flat No Lead (QFN) three dimension (3D) stacked-die semiconductor package. Reducing the copper thickness is understood to present various thermal and reliability failure mode and mechanisms, such as die cracking and delamination. However, no in-depth study has been pursued in order to determine the capability … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Banks Merger on Electronic Banking Services CompetencyAhmad Zakaria SiamProblem statement: This study is conducted to present benefits and consequences of latest technology used in banking industries. In addition, it has focused on the dynamics of banking sector, electronic banking services and new courses especially with mergers that constitute most of these mechanisms. Approach: The study discussed this new activity and the extent of response level of services while … …Journal of Social Sciences, Vol. 5, Issue 1 · 31 Mar 2009 · 7,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Electrical Properties by Texturing Surface on GaAs Solar Cell EfficiencyH. Abdullah, A. Lennie, M. J. Saifuddin, I. AhmadProblem statement: This project discusses on the method to resolve the optical losses problem that have been hindering the totality efficiency of the photovoltaic. Solar cell simulation could be useful for time saving and cost consumption. The Silvaco software is not widely used in designing the 2D solar cell devices because there is lots of 1D, 2D and 3D-simulation beside … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,790 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of Farmers Willingness to Pay for Wheat Consultant Engineers Project: In IranAli Asadi, Morteza Akbari, Hossain Shabanali Fami, Amir AlambaigiProblem statement: Public extension performance in many developing countries including Iran is not up to the expectation of farming community. Further, in recent years, many governments are very reluctant to shoulder huge financial investment for public extension. Hence, extension specialists and policy makers propose privatization of extension services in developing countries. Approach: Considering existing agricultural extension scenario, a study designed … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,412 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Rheological Properties of Bio Mastic AsphaltR. Muniandy, H. Jafariahangari, R. Yunus, S. HassimDue to the high oil prices the price of asphalt binder has increased tremendously. This scenario has warranted demand for higher viscosity cheaper asphalt for pavement construction.
