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

open access: yesInternational 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 ...

Tourism and Sustainable Development in the Mediterranean: Evidence From Robust Panel CS‐ARDL Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite the Mediterranean region's critical dependence on tourism, the empirical relationship between tourism development and multidimensional sustainable development remains underexplored. Existing studies predominantly rely on unidimensional sustainability proxies, failing to capture the holistic nature of sustainability. This study examines
