Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

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.

Machine Learning‐Assisted Optimization for Dynamic Supply Network Design in the Additive Manufacturing Platform

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Distributed manufacturing enabled by additive manufacturing (AM) allows supply chains to rapidly adapt to changing market conditions through flexible facility relocation and capacity adjustment. However, existing studies largely overlook the logistical aspects of AM‐based supply chains and typically treat facility location and logistics ...

Chronic high‐altitude exposure and intracerebral hemorrhage: A novel perspective from the vascular‐immune‐neuronal network

Neuroprotection, EarlyView.
Long‐term chronic high‐altitude hypobaric hypoxia increases susceptibility to ICH, particularly among migrant populations lacking EPAS1/SENP1 adaptive genetic variants relative to high‐altitude indigenous residents. Persistent hypoxia initiates blood–brain barrier (BBB) breakdown, aberrant glial and immune activation, and progressive neuronal injury ...

A Supervised Learning Framework for Accelerating Solvers and Metaheuristics in Routing Problems

Networks, EarlyView.
ABSTRACT Routing problems such as the traveling salesman problem (TSP) and the capacitated vehicle routing problem (CVRP) are computationally challenging due to the exponential growth of their feasible solution spaces with increasing instance size.
