On the Optimality of the Kitanidis Filter

2020 · HAL (Le Centre pour la Communication Scientifique Directe)

As a natural extension of the Kalman filter to systems subject to arbitrary unknown inputs, the Kitanidis filter has been designed by one-step minimization of the trace of the state estimation error covariance matrix. This …

Multiferroic Magnon Spin-Torque Based Reconfigurable Logic-In-Memory

2023 · arXiv (Cornell University)

Magnons, bosonic quasiparticles carrying angular momentum, can flow through insulators for information transmission with minimal power dissipation. However, it remains challenging to develop a magnon-based logic due to the lack of efficient electrical manipulation of …
