A method to deduce the characteristics of rail corrugation was developed and presented in this paper.It has been found that noise and vibration in the train vehicle were primarily contributed by rail corrugation and wheel polygonalisation.As the characteristics of Terminals wheel sets of a particular train can be assumed to be unchanged during a tr
The vibration caused by the movement of internal actuating components within an acoustic underwater glider can interfere with onboard sensors.However, as a new vibration-damping material, phononic crystals can effectively reduce this impact.Using simulation and an underwater test, this work studied the vibration-damping mechanism of the phononic cr
In this study, we present a novel approach for music emotion recognition that utilizes a stacked ensemble of models integrating audio and lyric features within a structured song framework.Our methodology employs a sequence of six specialized base models, each designed to capture critical features from distinct song segments: verse1, chorus, and ver
Fringe projection profilometry (FPP) plays an important role in the quality control of complex surface workpieces.Simulation using realistic image synthesis referring to physical sensors provide valid measures for the design and optimization of FPP systems.In the simulation of FPP, ray tracing can simulate the fringe image acquisition Dip Powders p
This paper explores the application of boron oxide (B2O3) as a sintering additive in silicon-based (SiO2) ceramics, focusing on its impact on the sintering process and resulting ceramic properties.Composite silicon-based ceramic shells with boron oxide content ranging from 0 to 4 Wt% were prepared using digital light processing (DLP) technology.Thi
