about to represent. Once the membership function has been established (estimated or defined), the concept is described very precisely as the membership values are exact numerical quantities. This seems to raise a certain dilemma of excessive precision in describing imprecise phenomena. In fact, this concern has already sparked a lot of debates starting from the very inception of fuzzy sets.” Co...

This paper considers the power capture control problem of variable-speed wind turbine (VSWT) systems with flexible shaft. The objective is to optimize energy by tracking desired output. A novel command filter based adaptive signal feedback (PSF) method proposed design PSF controller for non-affine nonlinear VSWT a two-mass model which parameters are totally unknown. compensation dynamic adaptab...

Abstract Due to the presence of two opposite directional thinking in relationships between countries and communication systems, systems may not always be balanced. Therefore, perfectness relations are highly important. It comes from how much they were connected each other for communication. In this study, first perfectly regular bipolar fuzzy graph is introduced examined regularity nodes. Then,...

A graph G is said to have a totally magic cordial labeling with constant C if there exists a mapping f : V (G) ∪ E(G) → {0, 1} such that f(a) + f(b) + f(ab) ≡ C (mod 2) for all ab ∈ E(G) and |nf (0) − nf (1)| ≤ 1, where nf (i) (i = 0, 1) is the sum of the number of vertices and edges with label i. In this paper, we give a necessary condition for an odd graph to be not totally magic cordial and ...
