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 · 8,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractResidues of Complex Functions with Definite and Infinite Poles on X-axisAbbas Y. AL-Bayati, Sasan A. Al-ShwaniProblem statement: One of the most popular areas in the mathematics is the computational complex analysis. In this study several computational complex techniques were investigated and implemented numerically. Objective: This study produced new procedures to compute the residues of complex functions by changing their numerator from a constant number to either even or odd function. Approach: In this project we … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 7,049 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Culture, Policy and Traditional Knowledge to Improve Engagement in Science CoursesLawrence K. Duffy, Catherine Hurt Middlecamp, Anna Godduhn, Cindy E. FabbriProblem statement: In our undergraduate science courses, we need to engage students by including the current issues and concerns of our students as well as recognizing the place-based context in which they learn. Including culture, policy and traditional knowledge when it intersects with a chemical principle and a challenging real world issue adds concreteness to the scientific process. Approach: Science … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractRETRACTED: Application of Sivasubramanian Kalimuthu Hypothesis to TrianglesM. SivasubramanianAt the request of the Editor-in-Chief, the Journal of Mathematics and Statistics has decided to retract the manuscript titled "Application of Sivasubramanian Kalimuthu Hypothesis to Triangles" authored by M. Sivasubramanian, published in Volume 5, Issue 2 with the page numbering 90-92. The authors have falsified findings and the article contains unsubstantiated claims and was accepted because of an administrative error. … …Journal of Mathematics and Statistics, Vol. 5, Issue 2 · 30 Jun 2009 · 7,646 accessesView PDFCite

Research ArticleOpen accessIn the abstractFactors Affecting the Standard of Female Education: A Case Study of Senior Secondary Schools in the Kassena-Nankana DistrictI. A. Adetunde, Akampae Peter AkensinaThis study presents the current factors affecting the standard of female education in the Kassena-Nankana district in Upper East Region of Ghana. Poverty, long-held negative attitudes about women's intellectual capabilities, teenage pregnancy, early marriage, examination failure in mathematics and science and the traditional division of household labour are among the many factors that continue to keep vast numbers of girls … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlmost Graded Prime IdealsAmeer Jaber, Malik Bataineh, Hani KhashanProblem Statement: Graded commutative ring with unity over an abelian group were introduced by many authors such as T. Y. Lam and C. T. C. Wall, and almost prime ideals over commutative rings with unity were introduced by S.M. Batwadeker and P.K. Sharma, and this forced us to try to extend the theory of almost and n-almost prime ideals to … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,030 accessesView PDFCite

Research ArticleOpen accessIn the abstractA New Approach to Solve Nonlinear Partial Differential EquationsAbdoul R. Ghotbi, M. A. Mohammadzade, A. Avaei, M. KeyvanipoorNonlinear phenomena play a crucial role in applied mathematics and physics. Explicit solutions to the nonlinear equations are of fundamental importance. Various methods for obtaining explicit solution to nonlinear evolution equations have been proposed. In this letter homotopy perturbation method (HPM) is employed for solving one-dimensional non-homogeneous parabolic partial differential equation with a variable coefficient and a system of nonlinear … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 6,916 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Sophistication and Differentiated Emotions during Mathematical Problem SolvingBradford D. Allen, James CarifioGeorge Polya, author of Mathematical Discovery and the enduring best seller How to Solve It: A New Aspect of Mathematical Method, claims that more sophisticated people experience more differentiated emotion during mathematical problem solving, a claim that has been untested for nearly fifty years. Using instruments that measure ongoing evaluations and emotion in real time, and traits that reflect mathematical … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,575 accessesView PDFCite
