摘要:Chatter is a self-excited vibration between the workpiece and tool with negative effects. In this work, a chatter detection method is proposed based on synchrosqueezing transform (SST) of sound signals. Firstly, the SST is used to analyze the sound signals recorded with the ...

摘要:The continuous wavelet transform (CWT) is one of the crucial damage identification tools in the vibration-based damage assessment. Because of the vanishing moment property, the CWT method is capable of featuring damage singularity in the higher scales, and separating the global t...

摘要:The wavelet finite element methods (WFEMs) own higher calculation accuracy and efficiency for structure analysis. Unfortunately, the existing WFEMs are still limited in low-frequency domain when capturing dynamic characteristics of thin plate. This paper proposes the wavelet mult...

摘要:The authors describe a sensitive method for determination of glutathione (GSH) that is based on a thiol-triggered inner filter effect on the fluorescence of N-doped carbon dots (N-doped CDs). N-doped CDs with a quantum yield as high as 31% were prepared by a one-pot procedur...

摘要:A hybrid method is proposed to properly identify multiple damages for plate structures in this work. In the stage of damage localization, singular value decomposition (SVD) is applied to reveal singularities in modal shapes, and hence to detect the damage locations. In the stage ...

摘要:In this paper, the Fourier spectrum-based strain energy damage detection method for beam-like structures is proposed based on the discrete Fourier transform. The classical strain energy damage detection method localizes damage by the comparison of the strain energy between the in...

摘要:Abstract(#br)Both high energy density and high energy efficiency are indispensable as considering antiferroelectric materials for pulse power capacitor applications. However, the electrical hysteresis will inevitably limit the energy efficiency reported in previous literatures. I...
