Automated Transmissibility‐Based Damage Detection for Output‐Only Systems

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
In this study, an automated transmissibility‐based procedure for damage detection is developed for output‐only systems. The application of transmissibility has been previously investigated for damage detection. Despite the advancements, current techniques are not applicable in a general way, as vast experience or expert knowledge is needed to achieve ...

Time‐attentive fusion network: An efficient model for online detection of action start

IET Image Processing, Volume 18, Issue 7, Page 1892-1902, 29 May 2024.
Here, a novel Time‐Attentive Fusion Network (TAF‐Net) is introduced to address the requirements of improved action detection accuracy and operational efficiency in the task of online detection of action start. The proposed model not only learns valuable sequence information for precise detection but its linear computational complexity and parallelism ...

Estimation of Joint Parameters Using Frequency‐Based Substructuring Techniques

International Journal of Distributed Sensor Networks, Volume 2024, Issue 1, 2024.
This study presents frequency‐based substructuring (FBS) techniques and an identification method for predicting joint parameters. Two FBS techniques, FBS‐1 and FBS‐2, were derived by assuming pseudomasses at the joint nodes between adjacent substructures.
