Background & Objective: Gliomas are the most common type of primary intracranial tumors in adults. The expression of estrogen receptors varies in different grades of glial tumors, and some studies have suggested that this expression might have a prognostic value. It seems that estrogen receptor expression negatively correlates with the histological grade of gliomas. In the pres...

In this note, by using the concept of Bipolar-valued fuzzy set, the notion of bipolar-valued fuzzy BCK/BCI-algebra is introduced. Moreover, the notions of (strong) negative s-cut (strong) positive t-cut are introduced and the relationship between these notions and crisp subalgebras are studied.

To plan a water resources system, fuzzy theory is introduced to handle uncertain future information. Representing runoff hydrograph and future water demand with fuzzy membership functions, the optimal site and scale of the system are decided through fuzzy linear programming. Then the construction schedule is calculated through fuzzy dynamic programming, under the conditions of limited finance a...

Background: Presence of discordance between the Gleason score on needle biopsy and the score of radical prostatectomy specimen is common and universal. In this study, we determined the accuracy of Gleason grading of biopsies in predicting histological grading of radical prostatectomy specimens and the degree of overgrading and undergrading of prostatic adenocarcinoma i...

Assessing student mathematical knowledge is an important factor in the mathematics learning process because students obtain feedback to improve their and learning. Despite importance of assessment, several researchers have shown that grades comprise noncognitive metacognitive factors teachers’ prejudices beliefs. One method a more objective view through standardized assessments. In this paper, ...

Let G= (V,E,σ,μ) be a simple connected undirected fuzzy graph. In this paper, we use a fuzzy graph model to represent a traffic network of a city and discuss a method to find the different type of accidental zones in a traffic flows. Depending on the possibility of accident, this paper classifies accidental zone of a traffic flow into three type’s namely α-strong, β-strong and δ-strong accident...

Childhood autism is one of the most common developmental disorders in children, whose disabilities generally tend to follow through adulthood. The therapy given to an autistic child depends on its accurate assessment, which is a challenging clinical decision making problem. This paper describes the application of functional fuzzy model in autism assessment support systems. The fuzzy model uses ...

After a presentation of the complexity to apply the fuzzy logic on industrial systems, we present the issues involved in the application of the fuzzy logic particularly the way to approach a control or classification problem. In order to deal with these issues, we present a case study of a grading system of cereals that allows us to determine the price of transactions of cereals (Durum wheat, S...
