1 This paper presents a new technique for the design of real-time controllers based on a hybrid approach which integrates several control strategies, such as intelligent controllers (e.g., arti cial neural networks, fuzzy systems), traditional linear controllers, nite state automata. An integrated programming environment, called EL-SIM, is also presented, suited for developing high-performance ...

We introduce bi-capacities as a natural generalization of capacities (or fuzzy measures) through the identity of Choquet integral of binary alternatives with fuzzy measures. We examine the underlying structure and derive the Möbius transform of bi-capacities. Next, the Choquet and Sugeno integrals w.r.t bicapacities are introduced. It is shown that symmetric and asymmetric integrals are recover...

We use covers of the universal set to de-ne approximation operators on the power set of the given set. In Section 1, we determine basic properties of the upper approximation operator and show how it can be used to give algebraic structural properties of certain subsets. We de-ne a particular cover on the set of ideals of a commutative ring with identity in such a way that both the concepts of t...

In this work we give a state-of-the-art review of two of the most established classes of fuzzy implications, viz., (S,N)and R-implications. Firstly, we discuss their properties, characterizations and representations. Many new results concerning fuzzy negations and (S,N)-implications, notably their characterizations with respect to the identity principle and ordering property, are presented, whi...

Distinct so far existing arithmetics of fuzzy numbers, usually stemming from the Zadeh’s extensional principle, do not preserve some of the important properties of the standard arithmetics of real numbers. Although one cannot expect that a generalization of the standard arithmetic will preserve precisely all its properties, the most important properties should be preserved at least in a weakene...

The biometric systems that source the single biometric identifier with the purpose of personal identification are considered poor in the performance evaluation of requirements. In this paper the study of fingerprint verification is carried out using the integration of three unimodal techniques. A Fuzzy based decision making model is employed for accepting inputs from three recognition methods t...

personal authentication and identification as compared to the traditional authentication methods. Biometric templates are vulnerable to variety of attacks due to their inherent nature. When a person's biometric is compromised his identity is lost. In contrast to password, biometric is not revocable. Therefore, providing security to the stored biometric template is very crucial. Crypto biometric...
