ON FUZZY NEIGHBORHOOD BASED CLUSTERING ALGORITHM WITH LOW COMPLEXITY

Gozde Ulutagay; Efendi Nasibov

Volume 10, Issue 3 , May and June 2013, Pages 1-20

Abstract
  The main purpose of this paper is to achieve improvement in thespeed of Fuzzy Joint Points (FJP) algorithm. Since FJP approach is a basisfor fuzzy neighborhood based clustering algorithms such as Noise-Robust FJP(NRFJP) and Fuzzy Neighborhood DBSCAN (FN-DBSCAN), improving FJPalgorithm would an important ...  Read More

OPTIMAL CONTROL OF FUZZY LINEAR CONTROLLED SYSTEM WITH FUZZY INITIAL CONDITIONS

Marzieh Najariyan; Mohamad Hadi Farahi

Volume 10, Issue 3 , May and June 2013, Pages 21-35

Abstract
  In this article we found the solution of fuzzy linear controlled systemwith fuzzy initial conditions by using -cuts and presentation of numbersin a more compact form by moving to the eld of complex numbers. Next, afuzzy optimal control problem for a fuzzy system is considered to optimize theexpected ...  Read More

$\mathcal{I}_2$-convergence of double sequences of\\ fuzzy numbers

Erdinc. Dundar; Ozer Talo

Volume 10, Issue 3 , May and June 2013, Pages 37-50

Abstract
  In this paper, we introduce and study the concepts of $\mathcal{I}_2$-convergence, $\mathcal{I}_2^{*}$-convergence for double sequences of fuzzy real numbers, where $\mathcal{I}_2$ denotes the ideal of subsets of $\mathbb N \times \mathbb N$. Also, we study some properties and relations of them.  Read More

ON APPROXIMATE CAUCHY EQUATION IN FELBIN'S TYPE FUZZY NORMED LINEAR SPACES

I. Sadeqi; F. Moradlou; M. Salehi

Volume 10, Issue 3 , May and June 2013, Pages 51-63

Abstract
  n this paper we study the Hyers-Ulam-Rassias stability of Cauchyequation in Felbin's type fuzzy normed linear spaces. As a resultwe give an example of a fuzzy normed linear space such that thefuzzy version of the stability problem remains true, while it failsto be correct in classical analysis. This ...  Read More

ALGEBRAICALLY-TOPOLOGICAL SYSTEMS AND ATTACHMENTS

Anna Frascella; Cosimo Guido; Sergey A. Solovyov

Volume 10, Issue 3 , May and June 2013, Pages 65-102

Abstract
  The paper continues the study of the authors on relationships between \emph{topological systems} of S.~Vickers and \emph{attachments} of C.~Guido. We extend topological systems to \emph{algebraically-topological systems}. A particular instance of the latter, called \emph{attachment system}, incorporates ...  Read More

Abstract
  We present some model theoretic results for {\L}ukasiewiczpredicate logic by using the methods of continuous model theorydeveloped by Chang and Keisler.We prove compactness theorem with respect to the class of allstructures taking values in the {\L}ukasiewicz $\texttt{BL}$-algebra.We also prove some ...  Read More

NEW RESULTS ON THE EXISTING FUZZY DISTANCE MEASURES

Saeid Abbasbandy; Soheil Salahshour

Volume 10, Issue 3 , May and June 2013, Pages 115-124

Abstract
  In this paper, we investigate the properties of some recently pro-posed fuzzy distance measures. We find out some shortcomings for these dis-tances and then the obtained results are illustrated by solving several examplesand compared with the other fuzzy distances.  Read More

representation theorems of $L-$subsets and $L-$families on complete residuated lattice

Hui Han; Jinming Fang

Volume 10, Issue 3 , May and June 2013, Pages 125-136

Abstract
  In this paper, our purpose is twofold. Firstly, the tensor andresiduum operations on $L-$nested systems are introduced under thecondition of complete residuated lattice. Then we show that$L-$nested systems form a complete residuated lattice, which isprecisely the classical isomorphic object of complete ...  Read More

Existence of Extremal Solutions for Impulsive Delay Fuzzy Integrodifferential Equations in $n$-dimensional Fuzzy Vector Space

Young Chel Kwun; Jeong Soon Kim; Jin Han Park

Volume 10, Issue 3 , May and June 2013, Pages 137-157

Abstract
  In this paper, we study the existence of extremal solutions forimpulsive delay fuzzy integrodifferential equations in$n$-dimensional fuzzy vector space, by using monotone method. Weshow that obtained result is an extension of the result ofRodr'{i}guez-L'{o}pez cite{rod2} to impulsive delay fuzzyintegrodifferential ...  Read More
