Low Complexity Modeling of Cross-Spectral Matrix and Its Application in the Non-Synchronous Measurements of Microphones Array

IEEE Access, 2021
The resolution related with the image quality of acoustic imaging using a microphone array is limited by the size and density of the array. However, non-synchronous measurements can exceed the constraints defined by measurements with a single fixed array.

Mechanical Vibration Test Equipment Design Laboratory Capacity for Automotive Industry

Journal of Batteries for Renewable Energy and Electric Vehicles, 2023
Vibration monitoring can also be used to find vibration levels caused by misaligned shafts and unbalanced masses, shaft misalignment of which is the root of vibration. In the UNDIRA Mechanical Engineering laboratory there is no mechanical vibration test equipment. In making the table frame and shaft, of course, it must be calculated accurately.
