Engineering in Practice
Identification of Anomalies in Systems Using Mechanical Waves: Applications in Pipe Networks, Railways and Arterial Networks
Date, time & venue
29 March 2023 (Wednesday), 17:00-18:00, Seminar via Zoom Meeting
HKIE Civil Division and The Hong Kong Polytechnic University
A significant part of the engineering practice is allocated to the identification or assessment of the existing infrastructures. A clever approach to make this assessment is to analyze the collected data from sensors. More specifically, exciting the target structures to generate a dynamic response, collecting the transient data by several sensors, and analyzing the responses subject to the imposed loads will provide valuable information about the system. While this approach is well established under the topic of damage detection in customary structures, its application in real practice for specific engineering systems is in its infancy.
This seminar will investigate this wave-based localization approach for three one-dimensional structures: Pipe Networks, Railways, and Arterial Networks. The limitations, potential outcomes, and future steps to refine these methods in terms of robustness, accuracy (resolution) and efficiency will be pointed out. The tradeoff between the need for a high-fidelity model or many datasets to perform a satisfactory localization will be clarified which in turn sets particular directions to proceed in order to enrich these methods in the future.
Free of Charge.
Dr Keramat is currently a Research Assistant Professor at The Hong Kong Polytechnic University (HK PolyU). Graduated with a PhD in Hydraulic Structures in 2011, he was previously affiliated as a visiting scholar at the Eindhoven University of Technology, visiting faculty member at the Tokyo Institute of Technology, a Research Associate at the Hong Kong University of Science and Technology, an Assistant Professor at the Jundi-Shapur University of Technology, and a visiting faculty member at the University of Alberta.
Dr Keramat’s research works are twofold: modeling waves and system identification. In particular, he is engaged in modeling transient waves, viscoelastic materials, non-Newtonian fluids, and fluid-structure interaction. He has also developed expertise in optimization and inverse problems, localization, defect detection, and uncertainty quantification. He has published over 50 articles in top peer-reviewed journals and has served as a reviewer to several professional hydraulic, structural, signal processing, and numerical-related journals.
