Breaking Extrapolation Barriers: Dual Innovations for Property and Component Design of Multi‐Component Alloy

Materials Genome Engineering Advances, EarlyView.
This study breaks extrapolation barriers in alloy design by merging symbolic regression with latent space sampling. The dual‐strategy framework enables accurate prediction of high‐hardness properties and navigates uncharted compositional spaces. The approach successfully designs novel high‐entropy alloys with hardness exceeding 863.5 HV, demonstrating ...

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

Mathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Deep Learning Improves Robustness of Voxelwise Kinetic Modeling for Hyperpolarized Carbon‐13 MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate whether deep learning improves the robustness of voxelwise kinetic parameter estimation from hyperpolarized (HP) 13C MRI compared with nonlinear least‐squares (NLLS) fitting. Methods A hybrid neural network (NN) was trained on synthetic pyruvate/lactate time courses generated from an open‐system two‐compartment HP 13C ...

Ultimate Intrinsic SNR Depends on B0 Orientation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This work aims to investigate the effect of B0$$ {B}_0 $$ orientation on the uiSNR in MRI. Methods Electromagnetic simulations were performed on both realistic body models and simplified geometric models. Comparisons between (1) opposite B0$$ {B}_0 $$ directions along the head‐foot (HF) axis, corresponding to head‐first and feet‐first ...

Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...

Designing ZV and ZVD Input Shapers Using the Designed Fixed Output Response Method to Suppress Residual Vibration of Overhead Crane Systems With Trolley Traveling and Payload Hoisting

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Classical Zero Vibration (ZV) and Zero Vibration and Derivative (ZVD) input shapers are designed around a fixed nominal natural frequency and cannot accommodate the time‐varying dynamics introduced when an overhead crane simultaneously travels and hoists a payload.
