##### 1. On weakly eR-open functions

M. Ozkoc; B. S. Ayhan

Volume 05, Issue 03 , Summer 2016, Pages 145-153

##### Abstract
The main goal of this paper is to introduce and study a new class of function via the notions of $e$-$\theta$-open sets and $e$-$\theta$-closure operator which are defined by Özkoç and Aslım [10] called weakly $eR$-open functions and $e$-$\theta$-open functions. Moreover, we investigate ...  Read More

##### 2. The directional hybrid measure of efficiency in data envelopment analysis

A. Mirsalehy; M. Rizam Abu Baker; L. S. Lee; Gh. R. Jahanshahloo

Volume 05, Issue 03 , Summer 2016, Pages 155-174

##### Abstract
The efficiency measurement is a subject of great interest. The majority of studies on DEA models have been carried out using radial or non-radial approaches regarding the application of DEA for the efficiency measurement. This paper, based on the directional distance function, proposes a new generalized ...  Read More

##### 3. Fuzzy soft ideals of near-subraction semigroups

Volume 05, Issue 03 , Summer 2016, Pages 175-186

##### Abstract
Our aim in this paper is to introduce the notion of fuzzy soft near-subtraction semigroups and fuzzy soft ideals of near-subtraction semigroups. We discuss some important properties of these new fuzzy algebraic structure and investigate some examples and counter examples.  Read More

##### 4. Solving systems of nonlinear equations using decomposition technique

Volume 05, Issue 03 , Summer 2016, Pages 187-198

##### Abstract
A systematic way is presented for the construction of multi-step iterative method with frozen Jacobian. The inclusion of an auxiliary function is discussed. The presented analysis shows that how to incorporate auxiliary function in a way that we can keep the order of convergence and computational cost ...  Read More

##### 5. Some topological operators via grills

A. A. Nasef; A. Azzam

Volume 05, Issue 03 , Summer 2016, Pages 199-204

##### Abstract
In this paper, we define and study two operators $\Phi^s$ and $\Psi^s$ with grill. Characterization and basic properties of these operators are obtained. Also, we generalize a grill topological spaces via topology $\tau^s$ induced from operators $\Phi^s$ and $\Psi^s$.  Read More

##### 6. Error estimation for nonlinear pseudoparabolic equations with nonlocal boundary conditions in reproducing kernel space

B. Zamanifar; T. Lotfi

Volume 05, Issue 03 , Summer 2016, Pages 205-214

##### Abstract
In this paper we discuss about nonlinear pseudoparabolic equations with nonlocal boundary conditions and their results. An effective error estimation for this method altough has not yet been discussed. The aim of this paper is to fill this gap.  Read More

##### 7. m-Projections involving Minkowski inverse and range symmetric property in Minkowski space

M. Saleem Lone; D. Krishnaswamy

Volume 05, Issue 03 , Summer 2016, Pages 215-228

##### Abstract
In this paper we study the impact of Minkowski metric matrix on a projection in the Minkowski Space M along with their basic algebraic and geometric properties.The relation between the m-projections and the Minkowski inverse of a matrix A in the minkowski space M is derived. In the remaining ...  Read More
