Improving the Characteristics of the Direct FOC Strategy in DFIG‐Based Wind Turbine Systems Using FOIDD and FOPD Controllers

open access: yesEnergy Science &Engineering, Volume 14, Issue 2, Page 999-1021, February 2026.
This study presents a new control strategy for doubly fed induction generator (DFIG) wind turbine systems to overcome the limitations of traditional direct field control using proportional‐integral (DFOC‐PI) regulators, which are sensitive to coefficient changes and lead to low power quality.

Modeling Marburg virus transmission in fuzzy-fractional framework using real epidemiological data of World Health Organization [PDF]

open access: yesAIP Advances
Highly contagious hemorrhagic fever known as Marburg Virus Disease (MVD), which is comparable to Ebola, is contracted by direct contact with an infected person’s bodily fluids.

Model‐Free Data‐Driven Computational Analysis for Soil Consolidation Problems

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 1166-1175, 10 February 2026.
ABSTRACT Soils are inherently uncertain natural materials. In geotechnical engineering, soil properties are fundamentally characterised by testing small samples. The results will then be utilised to determine appropriate geomaterial constitutive models and associated parameters for implementation in conventional computational procedures such as finite ...

Klein-Gordon-Langevin Quantum Geometry

open access: yes, 1993
We present a quantum geometric framework for stochastic quantisation in the case of a free Klein-Gordon field on Euclidean space. In this approach the noise is part of the background space, spacetime is fuzzy.

Bayesian Neural Network Prediction and Uncertainty Analysis of Bio‐Cemented Soil Strength

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 3, Page 1349-1366, 25 February 2026.
ABSTRACT Microbially induced carbonate precipitation (MICP) has emerged as a promising ground improvement technique, with MICP‐treated soils exhibiting substantial enhancements in strength. However, experimental results revealed significant variability in strength outcomes of MICP‐treated soils, even under identical treatment conditions and soil ...

Existence and Mittag–Leffler Stability for the Solution of a Fuzzy Fractional System with Application of Laplace Transforms to Solve Fractional Differential Systems

open access: yesAlgorithms
This study explores the existence and Mittag–Leffler stability of solutions for fuzzy fractional systems that include Caputo derivatives and ordinary derivatives with non-local conditions using the Schauder fixed-point theorem.

An Extended Krylov Subspace Method for Decoding Edge‐Based Compressed Images by Homogeneous Diffusion

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.
ABSTRACT The heat equation is often used to inpaint dropped data in inpainting‐based lossy compression schemes. We propose an alternative way to numerically solve the heat equation by an extended Krylov subspace method. The method is very efficient with respect to the computation of the solution of the heat equation at large times.

Aumann Fuzzy Improper Integral and Its Application to Solve Fuzzy Integro-Differential Equations by Laplace Transform Method

open access: yesAdvances in Fuzzy Systems, 2018
We introduce the Aumann fuzzy improper integral to define the convolution product of a fuzzy mapping and a crisp function in this paper. The Laplace convolution formula is proved in this case and used to solve fuzzy integro-differential equations with ...

Solving intuitionistic fuzzy fractional differential equations with $\psi$-Caputo fractional derivative

open access: yesResearches in Mathematics
In this research paper, we have attempted to establish the definition of the fractional derivative $\psi$-Caputo, the $\psi $-fractional integral, and the $\psi$-Laplace transform in the fuzzy intuitionistic sense, along with their properties ...
