we study interior operators and interior structures in a fuzzy setting.we investigate systems of “almost open” fuzzy sets and the relationshipsto fuzzy interior operators and fuzzy interior systems.

in this paper, we introduce and study the concept of $r$-fuzzy regular semi open (closed) sets in smooth topological spaces. by using $r$-fuzzy regular semi open (closed) sets, we define a new fuzzy closure operator namely $r$-fuzzy regular semi interior (closure) operator. also, we introduce fuzzy regular semi continuous and fuzzy regular semi irresolute mappings. moreover, we investigate the ...

This paper aims to introduce and study fuzzy hypersoft contra open, semi closed, closed maps in topological spaces. Basic properties of are analyzed with examples. Also, the relation between open maps, is discussed. It extended homeomorphism, C-homeomorphism its related characteristics also investigated. The set measure Hamming distance can be applied real-world decision-making problems contain...

aging has negative effects on motor and cognitive functions, so it is essential to identify appropriate strategies to prevent the decrease of motor and cognitive functions. the aim of this research was to investigate the effect of vitamin e supplement on motor activity and spatial learning in aged rats. 36 male albino – wistar aged rats were assigned to three groups of control, vitamin e and sh...

fuzzy newton-cotes method for integration of fuzzy functions that was proposed by ahmady in [1]. in this paper we construct error estimate of fuzzy newton-cotes method such as fuzzy trapezoidal rule and fuzzy simpson rule by using taylor's series. the corresponding error terms are proven by two theorems. we prove that the fuzzy trapezoidal rule is accurate for fuzzy polynomial of degree one and...

Since laparoscopic percutaneous extra peritoneal closure (LPEC) was introduced as a treatment for pediatric inguinal hernia in 2000, the procedure has been the most common surgical technique for repairing pediatric inguinal hernia in Japan. Research date shows that LPEC and conventional open repair have equivalent rates of recurrence and of postoperative complications. In addition, if contra la...

The present paper proposes a method of solving the fuzzy constraint satisfaction problems defined by Ruttkay. This method is based on CCM, which is a computational model for emergent computation, or for locality-based problem solving. CCM is a type of production system. It works stochastically, or randomly, and works with evaluation functions that are computed only with local information. CCM h...

We introduce the notion of (L, e)-filters with fuzzy partially order e on complete residuated lattice L. We investigate (L, e)-filters induced by the family of (L, e)-filters and functions. In fact, we study the initial and final structures for the family of (L, e)-filters and functions. From this result, we define the product and co-product for the family of (L, e)-filters and functions.
