Research ArticleOpen accessIn the abstractThe Magnetic Field Induced by a Lightning Strike's Indirect Effect Double Exponential Current WaveformScott L. Meredith, Susan K. Earles, Ivica N. Kostanic, Niescja E. TurnerProblem statement: Develop a new formula which describes the magnetic field induced by a lightning strike’s indirect effect double exponential current waveform. Approach: A novel approach for developing a closed-form solution for the magnetic field from the indirect effect double exponential current waveform will be presented. In the literature, models typically employ the pulse waveform to derive the corresponding electromagnetic … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 8,195 accessesView PDFCite
Research ArticleOpen accessIn the abstractLead Free Solder Joint Thermal Condition in Semiconductor PackagingM. Najib Harif, Allina Nadzri, Kamaruzaman JusoffProblem statement: Solder joints are responsible for both electrical and mechanical connections. Solder does not have adequate ductility to ensure the repeated relative displacements due to the mismatch between expansion coefficients of the chip carrier and the circuit board. Solder material plays a crucial role to provide the necessary electrical and mechanical interconnections in an electronic assembly. Finding a technique … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,165 accessesView PDFCite
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 · 8,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractK-Step Rational Runge-Kutta Method for Solution of Stiff System of Ordinary Differential EquationsP.O. Babatola, R.A. Ademiluyi, E.A. AreoThis study described the development, analysis and implementation of K-step implicit rational Runge-Kutta schemes for solution of stiff system of ordinary differential equations. Its development adopted taylor and binomial series expansion techniques to generate its parameters. The analysis of its basic properties adopted dalhquist a-stability model test equation and the results showed that the scheme was a-stable, consistent and convergent. … …Journal of Mathematics and Statistics, Vol. 4, Issue 3 · 30 Sep 2008 · 7,506 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review of the Recent Advances Made in the Black-Scholes Models and Respective Solutions MethodsYasir Hamad Al Saedi, Gurudeo Anand TularamThe Black-Scholes model has been a major advance in finance over a period of time; this paper examines this model in some detail, in terms of the latest developments in both analytical and numerical solutions. The paper initially briefly examines historical aspects but quickly moves to a critical analysis of the works in the applications, solutions and implications for the … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 8 Jan 2018 · 8,625 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Approach to Modelling of Flood Hazards in the Rapidly Growing City of Osogbo, Osun State, NigeriaSuleiman Abdul-Azeez Adegboyega, Oluchi Christiana Onuoha, Komolafe Akinola Adesuji et al.In recent times, the swift and uncoordinated urban expansion in the medium sized city of Osogbo has increasingly encroached on the environmental sensitive areas. This uncoordinated exploitation of the ecological fragile areas for urban development has triggered urban flooding, which poses serious threat to human lives and properties in the city. This study therefore utilized geospatial technologies to generate flood … …Space Science International, Vol. 4, Issue 1 · 8 Jan 2018 · 13,835 accessesView PDFCite
Research ArticleOpen accessIn the abstractCan Contract Marketing Motivate Farmers to Go Organic? Measuring the Moderation Effect of Contract MarketingGolnaz Rezai, Mad Nasir Shamsudin, Zainal Abidin Mohamed, Ting Jenn LingThe demand for organic food is growing in Malaysia due to consumer concerns for food safety, sustainable development, and urban expansion. However, the share of farmers engaged in this type of agriculture in Malaysia is notably low with only 72 (0.02%) organic vegetable farmers out of a total of 272,000 farmers in the country. Therefore, it is crucial to understand … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 1 · 4 Feb 2016 · 7,567 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnt Colony Optimization for Load Management Based on Load Shifting in the Textile IndustryChaimongkon Chokpanyasuwan, Tika Bunnag, Ratthasak PrommasThe textile industry is a complicated manufacturing industry because it is a fragmented and heterogeneous sector dominated by Small and Medium Enterprises (SMEs). There are various energy-efficiency opportunities that exist in every textile plant. However, even cost-effective options often are not implemented in textile plants mostly because of limited information on how to implement energy-efficiency measures. This paper presents the … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 9 Apr 2015 · 7,123 accessesView PDFCite
