Fuzzy determination of informative frequency band for bearing fault detection [PDF]

open access: yes, 2016
Detecting early faults in rolling element bearings is a crucial measure for the health maintenance of rotating machinery. As faulty features of bearings are usually demodulated into a high-frequency band, determining the informative frequency band (IFB ...

On third-order fuzzy differential equations by fuzzy Laplace transform

open access: yesBalıkesir Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2020
In this study, third-order fuzzy differential equations are studied using fuzzy Laplace transform under the approach of Hukuhara differentiability. Examples are solved. Graphics of the solutions are drawn. Conclusions are given.

Quantized Nambu-Poisson Manifolds and n-Lie Algebras

open access: yes, 2010
We investigate the geometric interpretation of quantized Nambu-Poisson structures in terms of noncommutative geometries. We describe an extension of the usual axioms of quantization in which classical Nambu-Poisson structures are translated to n-Lie ...

Heat Trace Asymptotics on Noncommutative Spaces [PDF]

open access: yes, 2007
This is a mini-review of the heat kernel expansion for generalized Laplacians on various noncommutative spaces. Applications to the spectral action principle, renormalization of noncommutative theories and anomalies are also considered.Comment: This is a

Fuzzy Fractional Evolution Equations and Fuzzy Solution Operators

open access: yesAdvances in Fuzzy Systems, 2019
In this paper, the fuzzy fractional evolution equations of order q (FFEE) with fuzzy Caputo fractional derivative are introduced. We study the existence and uniqueness of mild solutions for FFEE under some conditions.

Numerical analysis of fractional human liver model in fuzzy environment

open access: yesJournal of Taibah University for Science, 2021
Many papers have shown that fractional derivatives are preferable to other operators when the data or information is exact, but this is not the case in practice because we live in an uncertain environment.

Mathematical Model for Fault Handling of Singular Nonlinear Time-Varying Delay Systems Based on T-S Fuzzy Model

open access: yesMathematics, 2023
In this paper, a mathematical model based on the T-S fuzzy model is proposed to solve the fault estimation (FE) and fault-tolerant control (FTC) problem for singular nonlinear time-varying delay (TVD) systems with sensor fault.

Berezin-Toeplitz quantization for compact Kaehler manifolds. A Review of Results [PDF]

open access: yes, 2010
This article is a review on Berezin-Toeplitz operator and Berezin-Toeplitz deformation quantization for compact quantizable Kaehler manifolds. The basic objects, concepts, and results are given. This concerns the correct semi-classical limit behaviour of

Advanced control of non‐isothermal axial dispersion tubular reactors with recycle‐induced state delay

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Semi-Analytical Solutions for Fuzzy Caputo–Fabrizio Fractional-Order Two-Dimensional Heat Equation

open access: yesFractal and Fractional, 2021
In the analysis in this article, we developed a scheme for the computation of a semi-analytical solution to a fuzzy fractional-order heat equation of two dimensions having some external diffusion source term.
