ESTIMATING THE PARAMETERS OF A FUZZY LINEAR REGRESSION MODEL

A. R. Arabpour; M. Tata

Volume 5, Issue 2 , May and June 2008, Pages 1-19

Abstract
  Fuzzy linear regression models are used to obtain an appropriate linear relation between a dependent variable and several independent variables in a fuzzy environment. Several methods for evaluating fuzzy coefficients in linear regression models have been proposed. The first attempts at estimating the ...  Read More

GENERATING FUZZY RULES FOR PROTEIN CLASSIFICATION

EGHBAL G. MANSOORI; MANSOOR J. ZOLGHADRI; SERAJ D. KATEBI; HASSAN MOHABATKAR; REZA BOOSTANI; MOHAMMAD H. SADREDDINI

Volume 5, Issue 2 , May and June 2008, Pages 21-33

Abstract
  This paper considers the generation of some interpretable fuzzy rules for assigning an amino acid sequence into the appropriate protein superfamily. Since the main objective of this classifier is the interpretability of rules, we have used the distribution of amino acids in the sequences of proteins ...  Read More

ON ( $\alpha, \beta$ )-FUZZY Hv-IDEALS OF H_{v}-RINGS

B. Davvaz; P. Corsini

Volume 5, Issue 2 , May and June 2008, Pages 35-47

Abstract
  Using the notion of “belongingness ($\epsilon$)” and “quasi-coincidence (q)” of fuzzy points with fuzzy sets, we introduce the concept of an ($ \alpha, \beta$)- fuzzyHv-ideal of an Hv-ring, where , are any two of {$\epsilon$, q,$\epsilon$ $\vee$ q, $\epsilon$ $\wedge$ ...  Read More

A COMMON FIXED POINT THEOREM FOR SIX WEAKLY COMPATIBLE MAPPINGS IN M-FUZZY METRIC SPACES

Shaban Sedghi; K. P. R. Rao; Nabi Shobe

Volume 5, Issue 2 , May and June 2008, Pages 49-62

Abstract
  In this paper, we give some new definitions of M-fuzzy metric spaces and we prove a common fixed point theorem for six mappings under the condition of weakly compatible mappings in complete M-fuzzy metric spaces.  Read More

REDEFINED FUZZY SUBALGEBRAS OF BCK/BCI-ALGEBRAS

Arsham Borumand Saeid; Y. B. Jun

Volume 5, Issue 2 , May and June 2008, Pages 63-70

Abstract
  Using the notion of anti fuzzy points and its besideness to and nonquasi-coincidence with a fuzzy set, new concepts in anti fuzzy subalgebras in BCK/BCI-algebras are introduced and their properties and relationships are investigated.  Read More

MODULARITY OF AJMAL FOR THE LATTICES OF FUZZY IDEALS OF A RING

IFFAT JAHAN

Volume 5, Issue 2 , May and June 2008, Pages 71-78

Abstract
  In this paper, we construct two fuzzy sets using the notions of level subsets and strong level subsets of a given fuzzy set in a ring R. These fuzzy sets turn out to be identical and provide a universal construction of a fuzzy ideal generated by a given fuzzy set in a ring. Using this construction and ...  Read More

A NEW NOTION OF FUZZY PS-COMPACTNESS

Shi-Zhong Bai

Volume 5, Issue 2 , May and June 2008, Pages 79-86

Abstract
  In this paper, using pre-semi-open L-sets and their inequality, a new notion of PS-compactness is introduced in L-topological spaces, where L is a complete De Morgan algebra. This notion does not depend on the structure of the basis lattice L and L does not need any distributivity.  Read More

FUZZY SEMI-IDEAL AND GENERALIZED FUZZY QUOTIENT RING

YAO BINGXUE

Volume 5, Issue 2 , May and June 2008, Pages 87-92

Abstract
  The concepts of fuzzy semi-ideals of R with respect to H≤R and generalized fuzzy quotient rings are introduced. Some properties of fuzzy semiideals are discussed. Finally, several isomorphism theorems for generalized fuzzy quotient rings are established.  Read More

t-BEST APPROXIMATION IN FUZZY NORMED SPACES

S. M. Vaezpour; F. Karimi

Volume 5, Issue 2 , May and June 2008, Pages 93-99

Abstract
  The main purpose of this paper is to find t-best approximations in fuzzy normed spaces. We introduce the notions of t-proximinal sets and F-approximations and prove some interesting theorems. In particular, we investigate the set of all t-best approximations to an element from a set.  Read More
