Multiscale phase-space velocity diversity entropy and its application in marine engine cylinder liner wear fault diagnosis

Diversity entropy and its multiscale variants have shown promise for nonlinear dynamic feature extraction in marine engine fault diagnosis. However, existing diversity-entropy-based methods mainly describe the geometric properties of reconstructed phase-space trajectories, while...

Influence of glaze-iced insulators on force and motion characteristics of charged water droplets under DC voltage and natural icing test validation

Glaze ice exhibits high density and strong adhesion, readily forming ice bridges that impair insulator performance. While previous studies have primarily concentrated on macroscopic icing behavior under AC or DC fields, the role of icicles in affecting the motion of charged water...

Flow-Induced Deviation Mechanism and Structural Optimization of Engine Valves Under Braking Conditions

Under braking conditions, the valve is prone to lateral swing, which significantly compromises engine performance and longevity. Research indicates that the asymmetric vortex structures around the valve are one of the primary factors inducing effects such as lateral swing. Theref...

Sustainable preparation of lyocell‐grade bamboo dissolving pulp: A focus on process and material properties

Abstract This study investigated the sustainable preparation of Lyocell‐grade dissolving pulp from moso bamboo ( Phyllostachys pubescens ), with a focus on the influence of material properties and processing on dissolution behaviour in the NMMO/H 2 O system. The bamboo pulp exhib...
