Abstract Fuzzy Logic, introduced by Zadeh along with his introduction of fuzzy sets, is a
continuous multi-valued logic system. Hence, it is a generalization of the classical logic and …

Complex fuzzy sets utilize a complex degree of membership, represented in polar
coordinates, which is a combination of a degree of membership in a fuzzy set along with a …

Complex fuzzy sets, classes, and logic have an important role in applications, such as
prediction of periodic events and advanced control systems, where several fuzzy variables …

A complex fuzzy class is characterized by a pure complex fuzzy grade of membership. Pure
complex fuzzy classes are paramount in providing rich semantics for cases where the fuzzy …

For classical sets one has with the cumulative hierarchy of sets, with axiomatizations like the
system ZF, and with the category SET of all sets and map**s standard approaches toward …

The aim of this quantitative, exploratory and descriptive research is to know if teachers that
work in intercultural contexts develop ICT competences by using virtual platforms. The …

The current definition of complex fuzzy logic has two limitations. First, the derivation uses
complex fuzzy relations; hence, it assumes the existence of complex fuzzy sets. Second …

In this paper we propose a complex fuzzy logic (CFL) system that is based on the extended
Post (multi-valued logic) system (EPS) of order p>; 2, and demonstrate its utility for …

Disaster mitigation and management is one of the most challenging examples of decision
making under uncertain, missing, and sketchy, information. Even in the extreme cases …

Epidemical crisis prediction is one of the most challenging examples of decision making with
uncertain information. As in many other types of crises, epidemic outbreaks may pose …
