A Quantum Algorithm for Computing All Diagnoses of a Switching Circuit

no code implementations8 Sep 2022 Alexander Feldman, Johan de Kleer, Ion Matei

In this paper we provide a novel approach for computing diagnosis of switching circuits with gate-based quantum computers.

System Resilience through Health Monitoring and Reconfiguration

no code implementations30 Aug 2022 Ion Matei, Wiktor Piotrowski, Alexandre Perez, Johan de Kleer, Jorge Tierno, Wendy Mungovan, Vance Turnewitsch

The framework is based on a physics-based digital twin model and three modules tasked with real-time fault diagnosis, prognostics and reconfiguration.

Improving the Efficiency of Gradient Descent Algorithms Applied to Optimization Problems with Dynamical Constraints

no code implementations26 Aug 2022 Ion Matei, Maksym Zhenirovskyy, Johan de Kleer, John Maxwell

In our second algorithm, we use an ODE solver to reset the ODE solution, but no direct are adjoint sensitivity analysis methods are used.

Hybrid modeling: Applications in real-time diagnosis

no code implementations4 Mar 2020 Ion Matei, Johan de Kleer, Alexander Feldman, Rahul Rai, Souma Chowdhury

In this paper, we outline a novel hybrid modeling approach that combines machine learning inspired models and physics-based models to generate reduced-order models from high fidelity models.
