Explosion Response and Multiobjective Optimization of Butterfly-Shaped Circular Auxetic Cored Sandwich Panel Based on Machine Learning

Abstract In response to the urgent demand for blast-resistant protective structures, this study addresses two major limitations in existing research: the insufficient stiffness of conventional re-entrant auxetic honeycombs due to high porosity, and the lack of systematic multiobj...

Dynamic Voltage-Response Estimation for Blade-Tip Timing Sensors Based on EHHO-BP Network and Waveform Mapping

Blade-tip timing (BTT) sensor technology is widely used for non-contact blade vibration measurement. However, conventional BTT methods mainly rely on sparse time-of-arrival (TOA) information, which limits continuous sensor-domain characterization of blade vibration. To address th...

Characterization of B 2 O 3 ‐Modified CaF 2 –CaO–Al 2 O 3 Slag for Improved Electroslag Remelting Processes: Electric Conductivity and Surface Tension

The electrical conductivity and surface tension of the CaF 2 –CaO–Al 2 O 3 –MgO slag with varying B 2 O 3 content (2–7 mass%) were measured between 1573 and 1823 K using the four‐electrode method and the maximum‐pull method. XPS analysis was conducted to investigate the effect of...

Optimization of Land Pattern in Mining Area Based on the Improvement of Ecosystem Service Function—A Case Study of Fushun Mining Area

ABSTRACT Mining activities are prevalent worldwide and pose significant threats to the supply of ecosystem services (ESs) for humanity. Many mining areas face challenges related to recovery and reclamation following resource depletion. A key challenge for the sustainable developm...

Online Parameter-Reconfigured Model Predictive Control for Integrated Trajectory Tracking of Distributed Four-Wheel Steering Vehicles

To overcome the limitations of conventional model predictive control (MPC) for trajectory tracking of distributed-drive four-wheel-steering (4WS) vehicles, particularly its fixed weighting matrices and prediction and control horizons, this study investigates the integrated trajec...

Preparation and Comprehensive Properties of CeO2-Doped Composite Copper Foils

In the field of flexible electronics, traditional composite copper foils generally suffer from weak interfacial adhesion between the copper layer and polymer substrate, poor corrosion resistance, insufficient surface uniformity, and limited functional adaptability. To address the...

A novel metamaterial for tunable load-bearing and broadband vibration isolation based on combined double-helix and chiral unit cell

In the advanced high-performance mechanical systems, such as those in aerospace, automotive powertrains, and precision instrumentation, demand components that can simultaneously provide structural support and mitigate harmful vibrations. However, achieving an optimal balance betw...

Predefined‐Time Prescribed Performance Adaptive Tracking Control for Nonlinear Systems Relaxing Feasibility Condition

ABSTRACT This study addresses the tracking control issue for unknown nonlinear systems, focusing on predefined‐time prescribed performance. The core contribution lies in establishing a unified control framework that integrates deferred prescribed performance with predefined‐time...
