On dispersion curve coloring for mechanical metafilters [PDF]

open access: yesScientific Reports, 2022
This paper formalizes smooth curve coloring (i.e., curve identification) in the presence of curve intersections as an optimization problem, and investigates theoretically properties of its optimal solution.

Inversion of Rayleigh Wave Dispersion Curve Extracting from Ambient Noise Based on DNN Architecture [PDF]

open access: yesApplied Sciences, 2023
The inversion of the Rayleigh wave dispersion curve is a crucial step in obtaining the shear wave velocity (VS) of near-surface structures. Due to the characteristics of being ill-posed and nonlinear, the existing inversion methods presented low ...

Dispersion Curve Interpolation Based on Kriging Method [PDF]

open access: yesApplied Sciences, 2023
Volcanic eruptions significantly impact human life. However, real-time high-precision imaging in this context still has limitations. Spatial–temporal interpolation can replace real-time data imaging, in order to obtain the state of a given volcano at any

Quality influencing factors of dispersion curves from short period dense arrays based on a convolutional neural network across the north section of the Xiaojiang fault areaKey points

open access: yesEarthquake Science, 2023
The number of dispersion curves increases significantly when the scale of a short-period dense array increases. Owing to a substantial increase in data volume, it is important to quickly evaluate dispersion curve quality as well as select the available ...

Accelerated dispersion curve calculations for periodic vibro-acoustic structures

open access: yesFrontiers in Mechanical Engineering, 2022
Over the years, metamaterials have shown their potential in a wide range of different disciplines, e.g. optics, electromagnetics, dynamics etc. Metamaterials are, often periodic, engineered structures made of conventional materials but which exhibit ...

Phononic Crystal Made of Silicon Ridges on a Membrane for Liquid Sensing

open access: yesSensors, 2023
We propose the design of a phononic crystal to sense the acoustic properties of a liquid that is constituted by an array of silicon ridges on a membrane. In contrast to other concepts, the ridges are immersed in the liquid. The introduction of a suitable

Ultrasonic guided wave detection of U-shaped pipeline [PDF]

open access: yesMATEC Web of Conferences, 2020
The guided waves in the elbow was analyzed using semi- analytical finite element method, which was used to calculate the dispersion curves, along with the vibration deformation and energy flow density distribution of the elbow cross-section.
