A new similarity/distance measure between intuitionistic fuzzy sets based on the transformed isosceles triangles and its applications to pattern recognition

Expert Systems With Applications, 2019
Intuitionistic fuzzy set (IFS) is a representative model of fuzzy theory, and it is widely used to deal with fuzzy and uncertain problems in many practical applications.

Structure-property relationship in nonlinear optical materials with π-conjugated CO3 triangles

, 2020
It is well known that [CO3]2− groups are one kind of most promising structural groups for nonlinear optical (NLO) materials in the ultraviolet (UV) and visible spectral region, because their π-conjugated planar triangular configuration is favorable to ...

Triangles meeting triangles

The Mathematical Gazette, 2014
We consider two connected problems: • For a given but otherwise arbitrary triangle in the plane, to construct similar triangles which ‘meet’ this triangle. • To find the triangle so formed which has least area. 1. Constructing a triangle which meets another These problems beg the question of what is meant by ‘meet’ and we now aim to make this precise ...
