Axiomatic of Fuzzy Complex Numbers

open access: yesAxioms, 2012
Fuzzy numbers are fuzzy subsets of the set of real numbers satisfying some additional conditions. Fuzzy numbers allow us to model very difficult uncertainties in a very easy way.

Measurable prediction for the single patient and the results of large double blind controlled randomized trials. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: It has been shown that the clinical state of one patient can be represented by known measured variables of interest, each of which then form the element of a fuzzy set as point in the unit hypercube. We hypothesized that precise comparison of

Fuzzy solutions of some variants of the fractional order Korteweg-de-Vries equations via an analytical method

open access: yesAlexandria Engineering Journal, 2023
Under uncertainty, the analytical behaviour of fractional partial differential equations is frequently puzzling and challenging to predict. Therefore, in order to address these problems, it is essential to create a proper, extensive, and highly effective

A New Divergence Measure of Pythagorean Fuzzy Sets Based on Belief Function and Its Application in Medical Diagnosis

open access: yesMathematics, 2020
As the extension of the fuzzy sets (FSs) theory, the intuitionistic fuzzy sets (IFSs) play an important role in handling the uncertainty under the uncertain environments.

Measurement-theoretic frameworks for fuzzy set theory [PDF]

open access: yes, 1997
Two different but related measurement problems are considered within the fuzzy set theory. The first problem is the membership measurement find the second is property ranking. These two measurement problems are combined and two axiomatizations of fuzzy set theory are obtained.

A Theory for Measuring the Preference of Fuzzy Numbers

open access: yes2020 IEEE 20th International Symposium on Computational Intelligence and Informatics (CINTI), 2020
Here, sigmoid function-based preference measures for intervals and fuzzy numbers are introduced, and their main properties are outlined. Also, formulas for the numerical computation of the proposed preference measures are presented. Next, it is demonstrated that the proposed preference measures for intervals and fuzzy numbers are asymptotically the ...

Synthetic Emotions for Empathic Building

open access: yesMathematics, 2021
Empathic buildings are intelligent ones that aim to measure and execute the best user experience. A smoother and intuitive environment leads to a better mood. The system gathers data from sensors that measure things like air quality, occupancy, noise and

The Theory of Fuzzy Logic and its application to Real Estate Valuation [PDF]

open access: yes, 1998
Fuzzy logic is based on the central idea that in fuzzy sets each element in the set can assume a value from 0 to 1, not just 0 or 1, as in classic set theory. Thus, qualitative characteristics and numerically scaled measures can exhibit gradations in the

M-CFIS-R: Mamdani Complex Fuzzy Inference System with Rule Reduction Using Complex Fuzzy Measures in Granular Computing

open access: yesMathematics, 2020
Complex fuzzy theory has strong practical background in many important applications, especially in decision-making support systems. Recently, the Mamdani Complex Fuzzy Inference System (M-CFIS) has been introduced as an effective tool for handling events

A Measurement Theory Characterization of a Class of Dissimilarity Measures for Fuzzy Description Profiles [PDF]

open access: yes, 2020
We consider objects associated with a fuzzy set-based representation. By using a classic method of measurement theory, we characterize dissimilarity relations agreeing with a particular class of fuzzy dissimilarity measures. Dissimilarity measures in the considered class are those only depending on the attribute-wise distance of fuzzy description ...
