A Joint State-Parameter Identification Algorithm of a Structure with Non-Diagonal Mass Matrix Based on UKF with Unknown Mass

open access: yesBuildings, 2022
Inaccurate mass estimates have been recognized as an important source of uncertainty in structural identification, especially for large-scale structures with old ages.

On the structure of the fundamental subspaces of acyclic matrices with 0 in the diagonal

open access: yesThe American Journal of Combinatorics, 2023
A matrix is called acyclic if replacing the diagonal entries with \(0\), and the nonzero diagonal entries with \(1\), yields the adjacency matrix of a forest.

Diagonal Loading Beamforming Based on Aquila Optimizer

open access: yesIEEE Access, 2023
Traditional beamforming algorithms are only applicable to ideal environments. When the array antenna receives data under circumstances of small snapshots or large signal-to-noise ratio(SNR), noise eigenvalues of classic sample matrix inversion(SMI) and ...

Complete/incomplete multi‐view subspace clustering via soft block‐diagonal‐induced regulariser

open access: yesIET Computer Vision, 2021
This study proposes a novel multi‐view soft block diagonal representation framework for clustering complete and incomplete multi‐view data. First, given that the multi‐view self‐representation model offers better performance in exploring the intrinsic ...
