http://www.iiste.org/Journals/index.php/MTM/article/view/35229
<p>An attempt has been made to assess and identify the major variables that influence student academic achievement at college of natural and computational science of Wolaita Sodo University in Ethiopia. Study time, peer influence, securing first choice of department, arranging study time outside class, amount of money received from family, good life later on and father’s education level are major variables which influence the academic achievement of students at college of natural and computational science of Wolaita Sodo University, Ethiopia using binary logistic regression model.</p> <p><strong>Keywords: </strong>academic achievement, binary logistic regression, good life later on, peer influence, securing first choice of department, Wolaita Sodo University</p> <p><em> </em></p>Bereket Tessema Zewude7An Application of New Transform " Mahgoub Transform" to Partial Differential Equations
http://www.iiste.org/Journals/index.php/MTM/article/view/35230
<p>In this paper .The Mahgoub Transform of partial derivatives is derived, and its applicability demonstrated using five different partial differential equations. In this paper we find the particular solutions of these equations. The result reveals that the proposed method is very efficient, simple and can be applied to linear and nonlinear problems.</p> <p><strong>Keywords: </strong>Mahgoub Transform-Partial Differential Equations- wave equation- heat equation</p>Mohand M.

http://www.iiste.org/Journals/index.php/MTM/article/view/35231
<p>Many mathematical models are contributed to give rise to of linear and nonlinear integral equations.<strong> </strong>In this paper, we study the performance of recently developed technique homotopy perturbation method by implement on various types of linear and non-linear fuzzy Volterra integral equations of second kind, mixed fuzzy volterra fredholm integral equation and singular fuzzy integral equations. Obtained results show that technique is reliable, efficient and easy to use through recursive relations that involve integrals. Moreover, these particular examples show the reliability and the performance of proposed modifications.</p> <p><strong>Keywords: </strong>Homotopy perturbation method, linear fuzzy integral equations, non-linear fuzzy integral equations.</p>Hira Nosher7Common Fixed Point Theorem for Weakly Compatible Maps in Intuitionistic Fuzzy Metric Spaces

<p>In this paper, we prove some common fixed point theorem for weakly compatible maps in intuitionistic fuzzy metric space for two, four and six self mapping.</p>Madhu Shrivastava7Countability and Separability in Tritopological Spaces ( δ*-Countability and δ*-Separability)
http://www.iiste.org/Journals/index.php/MTM/article/view/35233
<p>In this paper, we will continue the basic specifications of Tritopological spaces begun by author. Furthermore, we introduce the new concepts and definitions of Countability and Separability in Tritopological spaces namely -Countability and -Separability. The properties for them are established. Also we introduce some definitions, theorems, examples and obtained some results.</p> <p><strong>Keywords: </strong> -First Countable space, -second Countable space, -separable space, Tritopological property, -dense, -local base, -base, -homeomorphism, -adherent point, -open set, Tritopological space.</p>Asmhan Flieh Hassan7
