Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

The 2‐D Orthogonal Packing Problem With Multiple Levels of Prioritization: A Spatial Optimization Perspective

Naval Research Logistics (NRL), EarlyView.
ABSTRACT This paper addresses two‐dimensional orthogonal packing within a confined space, integrating bin packing principles with facility layout concepts to address scenarios in which items must not only fit but also be arranged according to spatial priorities.

Monitoring shallow geothermal aquifers with active‐source distributed acoustic sensing: A prognostic feasibility study on the University of Leeds Geothermal Campus

Near Surface Geophysics, EarlyView.
Abstract The United Kingdom's shallow aquifers offer significant but underdeveloped geothermal energy resource. Seismic methods can help address this by improving the understanding of aquifer heterogeneity and potentially allowing long‐term monitoring of thermal plumes.

Multiscale Modeling of Hole Damage Evolution During Dynamic Installation of Interference Bushings in CFRP

Polymer Composites, EarlyView.
Multiscale modeling for dynamic installatioin. ABSTRACT The dynamic installation of metal interference bushings has demonstrated significant potential for improving the mechanical performance of carbon fiber‐reinforced polymer (CFRP) joints. However, the underlying mechanisms governing the remaining life enhancement remain insufficiently understood ...

Interfacially Engineered Alginate/Hydroxyapatite Biocomposites With High Strength and Toughness

Polymer Composites, EarlyView.
Pre‐crosslinking alginate with Ca2+ prior to hydroxyapatite (HAP) formation reduces residual Ca2+ bridging and promotes stronger carboxylate‐hydroxyapatite interfacial interactions, yielding composites with markedly higher strength, stiffness, and toughness than those prepared by the opposite sequence.
