FUZZY OBSERVER DESIGN WITH n-SHIFT MULTIPLE KEY FOR CRYPTOGRAPHY BASED ON 3D HYPERCHAOTIC OSCILLATOR

V. NATARAJAN; P. KANAGASABAPATHY; N. SELVAGANESAN; P. NATARAJAN

Volume 3, Issue 2 , September and October 2006, Pages 21-32

Abstract
  A fuzzy observer based scheme for synchronizing two hyperchaoticoscillators via a scalar transmitted signal for cryptographic application isproposed. The Takagi-Sugeno fuzzy model exactly represents chaotic systems.Based on the general fuzzy model, the fuzzy observer of a chaotic system isdesigned on ...  Read More

DIRECT ADAPTIVE FUZZY PI SLIDING MODE CONTROL OF SYSTEMS WITH UNKNOWN BUT BOUNDED DISTURBANCES

MOHAMMAD-REZA AKBARZADEH-TOTONCHI; REZA SHAHNAZI

Volume 3, Issue 2 , September and October 2006, Pages 33-51

Abstract
  An asymptotically stable direct adaptive fuzzy PI sliding modecontroller is proposed for a class of nonlinear uncertain systems. In contrast toother existing approaches of handling disturbances, the proposed approachdoes not require this bound to be known, only requiring that it exists.Moreover, a PI ...  Read More

SEMI $\theta$-COMPACTNESS IN INTUITIONISTIC FUZZY TOPOLOGICAL SPACES

I. M. Hanafy; A. M. Abd El-Aziz; T. M. Salman

Volume 3, Issue 2 , September and October 2006, Pages 53-62

Abstract
  The purpose of this paper is to construct the concept of semi$\theta$-compactness in intuitionistic fuzzy topological spaces. We give some characterizationsof semi $\theta$-compactness and locally semi -compactness. Also, wecompare these concepts with some other types of compactness in intuitionisticfuzzy ...  Read More

INTERVAL-VALUED FUZZY B-ALGEBRAS

Arsham Borumand Saeid

Volume 3, Issue 2 , September and October 2006, Pages 63-73

Abstract
  In this note the notion of interval-valued fuzzy B-algebras (briefly,i-v fuzzy B-algebras), the level and strong level B-subalgebra is introduced.Then we state and prove some theorems which determine the relationshipbetween these notions and B-subalgebras. The images and inverse images ofi-v fuzzy B-subalgebras ...  Read More

FUZZY SUBGROUPS AND CERTAIN EQUIVALENCE RELATIONS

APARNA JAIN

Volume 3, Issue 2 , September and October 2006, Pages 75-91

Abstract
  In this paper, we study an equivalence relation on the set of fuzzysubgroups of an arbitrary group G and give four equivalent conditions each ofwhich characterizes this relation. We demonstrate that with this equivalencerelation each equivalence class constitutes a lattice under the ordering of fuzzy ...  Read More
