1. A NEW APPROACH OF FUZZY NUMBERS WITH DIFFERENT SHAPES AND DEVIATION

A. Ghanizadeh; N. Parandin

Volume 6, Issue 2 , Summer 2014, Pages 730-736

Abstract
  In this paper, we propose a new method for fuzzy numbers. In this method, we assume that Ai= (ai1, ai2, ai3, ai4) is to be a fuzzy number. So, the convex combination of ai1 and ai2 and also the convex combination of ai3 and ai4 are obtained separately. Then, Mic and Mis that are to be the convex combinations ...  Read More

2. Unweighted p-center problem on extended stars

Jafar Fathali; Nader Jafari Rad; Sadegh Rahimi Sherbaf

Volume 6, Issue 2 , Summer 2014, Pages 737-744

Abstract
  An extended star is a tree which has only one vertex with degree larger than two. The -center problem in a graph  asks to find a subset  of the vertices of  of cardinality  such that the maximum weighted distances from  to all vertices is minimized. In this paper we consider ...  Read More

3. Application of G'/G-expansion method to the (2+1)-dimensional dispersive long wave equation

Jafar Biazar; Zainab Ayati

Volume 6, Issue 2 , Summer 2014, Pages 745-752

Abstract
  In this work G'/G-expansion method has been employed to solve (2+1)-dimensional dispersive long wave equation. It is shown that G'/G-expansion method, with the help of symbolic computation, provides a very effective and powerful mathematical tool, for solving this equation.  Read More
