Latin American Workshop on Structural Health Monitoring, 2023 A new methodology for wind turbine condition monitoring that utilizes vibration data and Mel-frequency cepstral coefficients (MFCCs) is being developed to accurately assess the condition of the wind turbine gearbox. Traditional condition monitoring techniques rely on physical inspections, which can be time-consuming and labor-intensive [1].

Downburst-Induced Vibration Coefficient of Long-Span Roof Structures
Buildings, 2022 Long-span roof structures are vulnerable to being damaged by downbursts due to the sensitivity of such structures to wind loads. However, there is still no simple and practical method for the downburst-resistant design of such structures to date ...

Improved damage detectability in a wind turbine blade by optimal selection of vibration signal correlation coefficients [PDF]
Structural Health Monitoring, 2016 The central message of this article is that for robust and efficient damage detection the damage sensitive features should be selected optimally in a systematic way such that only these features that contribute the most to damage detectability be retained.
