Novel Insights Into the Theory of Sequence Spaces for Fuzzy Numbers via Bessel Functions

IEEE Access
This paper introduces a novel theoretical framework for sequence spaces of fuzzy numbers based on Bessel statistical convergence and strong Bessel summability.

Group Decision-Making Model Based on Triangular Neutrosophic Sets for Service Quality Evaluation in Tourism Mobile E-Commerce [PDF]

Neutrosophic Sets and Systems
Triangular fuzzy numbers are frequently used by experts to assess their opinions in the group decision-making (GDM) paradigm. In this research, we used neutrosophic because preference connections with triangular fuzzy numbers are consistent.

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

AN EVOLUTIONARY ALGORITHM DETERMINING A DEFUZZYFICATION FUNCTIONAL

TASK Quarterly, 2007
Order fuzzy numbers are defined that make it possible to deal with fuzzy inputs quantitatively, exactly in the same way as with real numbers, together with four algebraic operations.

Fuzzy Decision Tree Based on Fuzzy Rough Sets and Z-Number Rules

Axioms
The decision tree algorithm is widely used in various classification problems due to its ease of implementation and strong interpretability. However, information in the real world often has uncertainty and partial reliability, which poses challenges for ...

On macroeconomic values investigation using fuzzy linear regression analysis [PDF]

Computational Methods in Social Sciences, 2017
The theoretical background for abstract formalization of the vague phenomenon of complex systems is the fuzzy set theory. In the paper, vague data is defined as specialized fuzzy sets - fuzzy numbers and there is described a fuzzy linear regression model

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

Advanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

Pricing Currency Option Based on the Extension Principle and Defuzzification via Weighting Parameter Identification

Journal of Applied Mathematics, 2013
We present a fuzzy version of the Garman-Kohlhagen (FG-K) formula for pricing European currency option based on the extension principle. In order to keep consistent with the real market, we assume that the interest rate, the spot exchange rate, and the ...

Electric‐Current‐Assisted Nucleation of Zero‐Field Hopfion Rings

Advanced Materials, EarlyView.
This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external
