Another approach to soft rough sets

Theories of soft sets and rough sets are two different approaches to vagueness. A possible fusion of rough sets and soft sets is proposed by F.Feng et al. They introduce the concept of soft rough sets, where parametrized subsets of a universe set are basic building blocks for lower and upper approximations of a subset. In the present paper, a new approach is being introduced to study roughness ...

Rough ideals based on ideal determined varieties

The paper is devoted to concern a relationship between rough set theory and universal algebra. Notions of lower and upper rough approximations on an algebraic structure induced by an ideal are introduced and some of their properties are studied. Also, notions of rough subalgebras and rough ideals with respect to an ideal of an algebraic structure, which is an extended notion of subalgebras and ...

Ideal Soft Tissue Facial Profile in Iranian Males and Females: Clinical Implications

BACKGROUND Proper pre-operative facial analysis that includes a thorough evaluation of both the bony and soft tissue anatomy is paramount to success in performing aesthetic surgery of the face. Ethnic variations in soft tissue profile add an important variable to pre-operative facial analysis. The aim of our study was to determine the role of ethnic variations in soft tissue facial profiles th...

Interval valued intuitionistic fuzzy soft set relations

In this paper the concept of interval valued intuitionistic fuzzy soft set relations (IVIFSS-relations for short) is proposed. Our relations on interval valued intuitionistic fuzzy soft sets is an extension of the relations on intuitionistic fuzzy soft sets, introduced by Mukherjee and Chakraborty in 2009. The basic properties of the IVIFSS-relations are also presented and discussed. It is seen...

Local and Global Approximations for Incomplete Data

For completely specified decision tables lower and upper approximations are unique, the lower approximation is the largest definable set contained in the approximated set X and the upper approximation of X is the smallest definable set containing X. For incomplete decision tables the existing definitions of upper approximations provide sets that, in general, are not minimal definable sets. The ...
