A NEW FUZZY MORPHOLOGY APPROACH BASED ON THE FUZZY-VALUED GENERALIZED DEMPSTER-SHAFER THEORY

SAFAR HATAMI; BABAK N. ARAABI; CARO LUCAS

Volume 1, Issue 2 , September and October 2004, Pages 1-14

Abstract
  In this paper, a new Fuzzy Morphology (FM) based on the GeneralizedDempster-Shafer Theory (GDST) is proposed. At first, in order to clarify the similarity ofdefinitions between Mathematical Morphology (MM) and Dempster-Shafer Theory (DST),dilation and erosion morphological operations are studied from ...  Read More

FUZZY GRADE OF I.P.S. HYPERGROUPS OF ORDER 7

Piergiulio Corsini; Irina Cristea

Volume 1, Issue 2 , September and October 2004, Pages 15-32

Abstract
  i.p.s. hypergroups are canonical hypergroups such that$[\forall(a,x),a+x\ni x]\Longrightarrow[a+x=x].$i.p.s. hypergroups were investigated in [1], [2], [3], [4] and it was proved thatif the order is less than 9, they are strongly canonical (see [13]). In this paperwe obtain the sequences of fuzzy sets ...  Read More

SOME QUOTIENTS ON A BCK-ALGEBRA GENERATED BY A FUZZY SET

Abbas Hasankhani; Hamid Saadat

Volume 1, Issue 2 , September and October 2004, Pages 33-43

Abstract
  First we show that the cosets of a fuzzy ideal μ in a BCK-algebraX form another BCK-algebra  X/μ (called the fuzzy quotient BCK-algebra of X by μ). Also we show thatX/μ is a fuzzy partition of X and we prove several some isomorphism theorems. Moreover we prove that ...  Read More

PEDOMODELS FITTING WITH FUZZY LEAST SQUARES REGRESSION

JAHANGARD MOHAMMADI; SYED MAHMOUD TAHERI

Volume 1, Issue 2 , September and October 2004, Pages 45-61

Abstract
  Pedomodels have become a popular topic in soil science and environmentalresearch. They are predictive functions of certain soil properties based on other easily orcheaply measured properties. The common method for fitting pedomodels is to use classicalregression analysis, based on the assumptions of ...  Read More

FUZZY (POSITIVE, WEAK) IMPLICATIVE HYPER BCK-IDEALS

Mahmood Bakhshi; Rajab Ali Borzooei; Mohammad Mehdi Zahedi

Volume 1, Issue 2 , September and October 2004, Pages 63-79

Abstract
  In this note first we define the notions of fuzzy positive implicativehyper BCK-ideals of types 1,2,3 and 4. Then we prove some theorems whichcharacterize the above notions according to the level subsets. Also we obtainthe relationships among these notions, fuzzy (strong, weak, reflexive) hyperBCK-ideals ...  Read More
