Computational methods were used to reduce the dimensionality and to find clusters of multivariate data. The variables were the natural radioactivity contents and the texture characteristics of sand samples. The application of discriminate analysis revealed that samples with high negative values of the former score have the highest contamination with black… (More)

The basic concepts of some near open, near rough, near exact and near fuzzy sets are introduced and sufficiently illustrated. The topology induced by binary relations is used to generalize the basic rough set concepts. We introduce the near exactness and near roughness by applying the near concepts to make more accuracy for definability of sets. We give a… (More)

The purpose of the present work is to construct a new method for approximation of sets using two information systems simultaneously. Some properties and characterizations are given and a comparison with the previous sorts of approximation is obtained.

Most real life situations have uncertain concepts, the search for approximating uncertain concepts and measuring the accuracy of approximation is an important goal for researchers in many of theoretical and application fields. The purpose of this paper is to find topological approximation for uncertain concepts in information systems, and to compute some… (More)

In the expanding world the demand of electricity is increasing day by day. The power utilities are making continuous efforts to reduce the gap between supply and demand. The effect of various faults in power system leads to unplanned outages in power system, which makes the situation still worse. Power transformers are the heart of power system. They are… (More)

The process of changing a topology by some types of its local discrete expansion preserves s-closeness, S-closeness, semi-compactness, semi-T, semi-R, E {0,1,2}, and extremely disconnectness Via some other forms of such above replacements one can have topologies which satisfy separation axioms the original topology does not have

In rough set theory, the lower and upper approximation operators can be constructed via a variety of approaches. Various generalizations of rough approximation operators have been made over the years. This paper presents a framework for the study of rough sets and rough fuzzy sets on two universes of discourse. By means of a binary relation between two… (More)

In this paper we introduce two new types of equalities by using simply open sets namely lower equal upper equal and approximation (briey '; and h ) and we also introduce new concept of simply dense,simply codense sets by using simply open sets and we study some of thier properties.And also we obtian the reslut from the general relation we get the partion… (More)

Rough set theory is a powerful tool for dealing with uncertainty, granularity, and incompleteness of knowledge in information systems. In this paper we study covering-based rough fuzzy sets in which a fuzzy set can be approximated by the intersection of some elements in a covering of the universe of discourse. Some properties of the covering-based fuzzy… (More)
