Research ArticleOpen accessIn the abstractEffect of Manufacturing Stresses to Die Attach Film Performance In Quad Flatpack No-Lead Stacked Die PackagesM. F. Rosle, I. Abdullah, S. Abdullah et al.Problem statement: Repeated heat cure during assembly processes affected the Die Attach Film (DAF) material properties and the effectiveness touched area that leads to weak die bonding and delamination. Suitable die attached condition and DAF material selection had been evaluated to achieve required reliability performance in the manufacturing of the 3D Quad Flat No-Lead (QFN) stacked die package. Approach: During … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,048 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Critical Review of Global Wind Power GenerationT. Ahilan, Dr. K.P. Mohammed, Dr. S. ArumughamThis research begins with an overview of wind development and installation-related trends, including trends in capacity growth. Development of wind power has reached a level of maturity, which could be taken upon for further novelty and growth in meeting the future energy needs in much greater proportion. Current research techniques are producing stronger, lighter and more efficient blades for the … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,485 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombustion of Bimodal Nano/Micro Aluminum Suspension with New Reaction Rate ModelM. Bidabadi, N. Moallemi, I. Shafieenejad, M. JadidiIn this study a mathematical model for combustion of bimodal particle in lean flow was developed. The difference between structure of flame in this work and previous ones was that, in those flame was divided by five zones and reaction rate was considered to be constant in reaction zones and also zero in post flame zone. In reality it was … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 6,794 accessesView PDFCite
Research ArticleOpen accessIn the abstractTwo Mathematical Modeling Approaches for Integrating Production and Transportation Decisions in the Process IndustryMohamed K. Omar, A. AjithaIn this study we focus on coordination of the production planning of finished products and intermediate products in the process industry. The problem consists of two manufacturing facilities with similar production environment, one producing the intermediates and the other producing end products that are separated by a distance. There is transportation between the facilities. The problem considered has been formulated … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Reliability and Availability Characteristics of Two Different Systems by Using Linear First Order Differential EquationsKhaled M. El-Said, Mohamed S. EL-SherbenyThis study deals with the reliability and availability characteristics of two different series system configurations. The second system differs from the first system due to the additional feature of preventive maintenance. The failure times of a components are assumed to be exponentially distributed with parameters α,β,α' and β', respectively. The replacement time distribution of each server is also exponentially distributed … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractVHDL Specification Methodology from High-level SpecificationM. Benmohammed, S. MernizDesign complexity has been increasing exponentially this last decade. In order to cope with such an increase and to keep up designers' productivity, higher level specifications were required. Moreover new synthesis systems, starting with a high level specification, have been developed in order to automate and speed up processor design. This study presents a VHDL specification methodology aimed to extend … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling of Wastewater Oxidation under Microgravity ConditionsBoyun Guo, Donald W. Holder, David S. SchechterVolatile removal assembly (VRA) is a module installed in the International Space Station for removing contaminants (volatile organics) in the wastewater produced by the crew. The VRA contains a slim pack bed reactor to perform catalyst oxidation of the wastewater at elevated pressure and temperature under microgravity conditions. Optimal design of the reactor requires a thorough understanding about how the … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,888 accessesView PDFCite
