This paper proposes a new method of face image feature extraction, namely, the fuzzy 2DFLD (F2DFLD) based on the 2D fisher discriminant criterion and fuzzy set theory. In the proposed method, we calculate membership degree matrix by FKNN, then we incorporate the membership degree into the definition of the between-class scatter matrix and within-class scatter matrix and get the fuzzy between-cl...

‎In this paper, a new class of fuzzy sets called fuzzy strongly ${{g}^{*}}$-closed sets is introduced and its properties are investigated. Moreover, we study some more properties of this type of closed spaces.

1 Overview This report is the extended version of PT99] and while they are some overlapping parts (mainly the results) we don't repeat here some of the examples given in PT99], even though we frequently refer to them. The overview of this report is as follows. In section 2 we present some aspects of our internal framework, called CoDi 1. This is a language and equational theory that combines a ...

The paper presents a form of rendering classical mathematical notions by formal theories over suitable t-norm fuzzy logics in such a way that references to real numbers are eliminated from definitions and theorems, being removed to the standard semantics of fuzzy logic. Several examples demonstrate how this move conceptually simplifies the theory in exchange for non-classical reasoning, facilit...

In this paper we examine the performance of fuzzy rule-based systems with classification priority for medical diagnosis problems. The assumption in this paper is that a classification priority is given a priori for each class in a pattern classification problem. Our fuzzy rulebased system consists of a set of fuzzy if-then rules that are automatically generated from a set of given training patt...

This thesis proposes a general framework for equational logic programming, called catf:gory­ based equational logic by placing the general principles underlying the design of the pro­ gramming language Eqlog and formulated by Goguen and Meseguer into an abstract form. This framework generalises equational deduction to an arbitrary category satisfy­ ing certain natural conditions; completeness i...

The class of radial fuzzy systems is introduced. The fuzzy systems in this class use radial functions to implement membership functions of fuzzy sets and exhibit a shape preservation property in antecedents of their rules. The property is called the radial property. It enables the radial fuzzy systems to have their computational model mathematically tractable under both conjunctive and implicat...

the public class parking as an essential component of a modern transport system within the city, provided spaces for the removal of stationary traffic in urban communication system, spaces to temporarily stop vehicles and thus the flow of traffic. locate the appropriate class parking using technological methods, particularly in metropolitan, maximum and optimum use of urban space, so improved p...
