Learning Structural Eigenmodes with Modal Operator Network (ModalONet)
Saad Waheed, Shabbir Ahmed
Neural operators such as the deep operator network (DeepONet) and the Laplace neural operator (LNO) are effective surrogates, but they are almost exclusively trained to reproduce t…
Koopman Spectral Analysis of Lithium-Ion Battery Dynamics: State of Charge as a Marginally Stable Observable
Bakhtiar Nafis, Khalid Mahmud Labib, Saad Waheed +1
Accurate state-of-charge (SOC) estimation remains a fundamental challenge in lithium-ion battery management systems because battery dynamics are highly nonlinear, operating-conditi…
Vision-Based Structural Damage Identification in Vibrating Beams via Dynamic Mode Decomposition
R K B M Rizmi, Shabbir Ahmed
Structural damage detection using non-contact sensing remains a challenging problem in structural health monitoring. This study presents a data-driven framework based on Dynamic Mo…
Operator-Theoretic and physics-guided Sequence Modeling of Lithium-Ion Battery Voltage Dynamics
Khalid Mahmud Labib, Inayat Rasool, Shabbir Ahmed
