Joint mixed-integer convex optimization of path, speed, and power in hybrid-electric ships
We present optimization models that simultaneously determine ship path, speed profile, and hybrid power system operations. Our approach integrates solar phot...

Hydropower generation fulfills 94% of Québec’s electricity needs, making efficient Short-Term Hydropower Scheduling (STHS) critical for daily operations. Thi...
BibTeX referenceDistributionally robust extended Kalman filtering for lithium-ion battery state-of-charge estimation
Lithium-ion batteries (LIBs) are currently the core energy storage component of electric vehicles (EVs). Real-time, accurate, and robust state-of-charge (SO...
BibTeX referenceAn improved approximation of metal accumulation in electric arc furnaces for ferrosilicon production
Accurate estimation of metal accumulation in electric arc furnaces (EAFs) is critical for maintaining stable ferrosilicon (FeSi) production and ensuring effe...
