The online estimation of the process noise covariance matrix (PNCM) in the inertial-based integrated navigation has always been a challenge due to the small magnitude of the PNCM and limited ...
There has been a great deal of attention on the online estimation of noise covariance matrices in Kalman filtering during recent decades. However, the existing methods face challenges in the ...
Recent advancements in photoclickable collagen-based bioresins enhance deep vat printing, enabling high-resolution tissue constructs for regenerative medicine.
Covariance ($\Sigma$): A $3\times3$ matrix that defines the shape, size, and orientation of the Gaussian. To ensure that the covariance matrix remains physically meaningful (positive semi-definite) ...
