Best Paper Award at COSEIK: Efficient Structural Analysis via Progressive Sketching
November 28, 2025
We are proud to announce that our research collaborated with Prof. Chandrajit Bajaj received the Best Paper Award at the recent COSEIK Academic Symposium. In this study, we introduced a Progressive Sketching-based High-Order Decomposition method designed to handle the complex spatiotemporal data inherent in large-scale structural systems. By integrating Thompson Sampling with randomized sketching, the proposed framework strategically balances exploration and exploitation to maximize sample efficiency. Validated using Tacoma Narrows Bridge footage, the method successfully reconstructed key structural patterns from sparse samples, offering a scalable computational framework for future data-driven structural health monitoring and vibration analysis.
Evaluating Repurposed Oil and Gas Platforms for Offshore Wind
Evaluating Repurposed Oil and Gas Platforms for Offshore Wind
July 2, 2025
As the offshore energy sector shifts from fossil fuels to renewable sources, repurposing aging oil and gas platforms offers a sustainable alternative to decommissioning. In a new study published in Applied Ocean Research, we assess the structural performance of such repurposed platforms for offshore wind energy generation. Using OpenFAST time-domain simulations, we estimate fatigue damage under nine representative sea states and identify critical stress points on the platform. Results show that lower-leg components are most vulnerable, particularly under high wind conditions that induce resonant responses. These findings inform future strategies for structural retrofitting and reuse planning in offshore wind deployment. https://doi.org/10.1016/j.apor.2025.104696
Optimizing Integrated Energy Systems with Co-Production
Optimizing Integrated Energy Systems with Co-Production
May 27, 2025
Grid-interactive energy systems with multiple co-products offer promising pathways for decarbonization, but their operational complexity poses significant modeling challenges. In a new study published in Computers and Chemical Engineering, we introduce a scalable computational framework for optimizing the integrated design and scheduling of such systems over 8,760 hours of annual operation. Applying the framework to a nuclear power plant coupled with high-temperature steam electrolysis (HTSE), we show that co-production can be economically competitive with standalone HTSE. Sensitivity analyses further highlight that early R&D efforts should focus on increasing current density to 3–4 A/cm² to improve economic feasibility. https://doi.org/10.1016/j.compchemeng.2025.109213
