The heart is the most important member of the human body. Its task is giving blood to all the members. Disruption in the work of the member makes up compromised the human health. Many factors affect the proper functioning of this organ. In this article we're going to design a system that will help to doctors in diagnosing heart disease. The rules of this system is extracted by consultation with...

Background and Aim: According to the definition proposed by WHO, social health is a health dimension that impacts, or is affected by, the two physical and mental dimensions. Based on the definition given by the Academy of Medical Sciences of Islamic Republic of Iran, social health includes reciprocal qualitative and quantitative behaviors by individuals towards welfare of the society. Pro-socia...

As main result of all our previous work we have now available a FSQL Server for Oracle Databases pro grammed in PL SQL This server allows us to query either a Fuzzy or Classic Relational Database with the FSQL language Fuzzy SQL The FSQL language is an extension of the SQL language which permits us to write exible or fuzzy conditions in our queries to a fuzzy or traditional database In this wor...

the pioneer work of image compression/reconstruction based onfuzzy relational equations (icf) and the related works are introduced. theicf regards an original image as a fuzzy relation by embedding the brightnesslevel into [0,1]. the compression/reconstruction of icf correspond to thecomposition/solving inverse problem formulated on fuzzy relational equations.optimizations of icf can be consequ...

In this paper, bi-matrix games are investigated based on L-R fuzzy variables. Also, based on the fuzzy max order several models in non-symmetrical L-R fuzzy environment is constructed and the existence condition of Nash equilibrium strategies of the fuzzy bi-matrix games is proposed. At last, based on the Nash equilibrium of crisp parametric bi-matrix games, we obtain the Pareto and weak Pareto...

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 the basis of the n-shift multiple state based key encryption algorithm.the scalar transmitted s...

a shortest path problem is a practical issue in networks for real-world situations. this paper addresses the fuzzy shortest path (fsp) problem to obtain the best fuzzy path among fuzzy paths sets. for this purpose, a new efficient algorithm is introduced based on a new definition of ideal fuzzy sets (ifss) in order to determine the fuzzy shortest path. moreover, this algorithm is developed for ...
