Towards Reduced Order Modelling of Cardiac Electroanatomical Mapping

Olivier Crabbe, Karim El Houari, Louis Rigal, Sophie Collin et autres

Ventricular tachycardia (VT) is a lethal heart rhythm disorder responsible for 80% of sudden cardiac deaths.Radiofrequency ablation (RFA) of VT is minimally invasive and potentially curative but target identification using cardiac electroanatomical mapping (EAM) is challenging.Personalized computer heart models may provide deeper …

Coupled Multiphysics Modeling of Lithium-Ion Batteries for Automotive Crashworthiness Applications

Anudeep Mallarapu, Iñaki Çaldichoury, P. L’Eplattenier, Nathaniel Sunderlin et autres

Abstract Considerable advances have been made in battery safety models, but achieving predictive accuracy across a wide range of conditions continues to be challenging. Interactions between dynamically evolving mechanical, electrical, and thermal state variables make model prediction difficult during mechanical abuse scenarios. …
