Semi‐autonomous Navigation of Magnetic Microcarriers for Knee Cartilage Regeneration

Advanced Intelligent Systems, Volume 8, Issue 4, April 2026.
Autonomous navigation of magnetic microcarriers in complex 3D environments is investigated through a semi‐autonomous strategy integrating magnetic actuation with monocular visual feedback. Real‐time global tracking is achieved via radio‐frequency‐based localization and depth estimation, while model‐based computation determines optimal steering forces ...

Numerical and Intelligent Modeling of MHD Casson Nanofluid Heat Transfer in Fractal Porous Cavities for Energy Systems

Engineering Reports, Volume 8, Issue 4, April 2026.
This study demonstrates that Al2O3–GNP hybrid nanofluids significantly enhance heat transfer in porous rectangular enclosures. Magnetic fields suppress velocity but raise temperature, while higher Biot and Brinkman numbers improve Nusselt number and entropy generation, highlighting effective thermal control in non‐Newtonian HNF systems.

A Force‐Based Identification Scheme for Constitutive Parameters Regularized by Admissible Elemental Internal Forces

Engineering Reports, Volume 8, Issue 4, April 2026.
The “E‐FEMU‐F loss” as a function of full‐field displacements, constitutive parameters, and “Admissible Elemental Internal Forces” (AEIFs). AEIFs are constructed from measured (integrated) external forces and optimized analytically, while constitutive parameters are inferred numerically to minimize the E‐FEMU‐F loss.

Mechanism and Control Analysis of Synchronous Frequency Resonance in Distributed Power Generation System Connected to Grid

Energy Science &Engineering, Volume 14, Issue 4, Page 2263-2276, April 2026.
Small‐signal modeling reveals that insufficient system damping positions conjugate poles near the imaginary axis, fundamentally explaining the SFR mechanism. A virtual resistance control is consequently proposed to damp the resonance and effectively suppress SFR, which is validated through Hardware‐in‐the‐Loop experiments.

Theoretical Model of Transient Regression of Thermoplastic Materials During Flame Spread: Vaporization; Permanent Mass Loss; Surface Shape

Fire and Materials, Volume 50, Issue 3, Page 227-240, April 2026.
ABSTRACT This article examines a transient, one‐dimensional model of surface regression during opposed flow flame spread over finite thickness, non‐charring thermoplastics. Gas to solid conductive transfer from the flame drives sample heating. The solid degrades into volatile fuel molecules in two stages: (1) the pre‐vaporization heat‐up stage and (2 ...
