Singular Spectrum Analysis for Modal Estimation from Stationary Response Only

open access: yesSensors, 2022
Conventional experimental modal analysis uses excitation and response information to estimate the frequency response function. However, many engineering structures face excitation signals that are difficult to measure, so output-only modal estimation is ...

On determinants identity minus Hankel matrix [PDF]

open access: yesBulletin of the London Mathematical Society, 2019
In this note, we study the asymptotics of the determinant $\det(I_N - H_N)$ for $N$ large, where $H_N$ is the $N\times N$ restriction of a Hankel matrix $H$ with finitely many jump discontinuities in its symbol satisfying $\|H\|\leq 1$. Moreover, we assume $ \in\mathbb C$ with $| |<1$ and $I_N$ denotes the identity matrix. We determine the first

Finite Sample Identification of Low-Order LTI Systems via Nuclear Norm Regularization

open access: yesIEEE Open Journal of Control Systems, 2022
This paper studies the problem of identifying low-order linear time-invariant systems via Hankel nuclear norm (HNN) regularization. This regularization encourages the Hankel matrix to be low-rank, which corresponds to the dynamical system being of low ...

Characterizations of matrix-valued asymmetric truncated Hankel operators

open access: yesBanach Journal of Mathematical Analysis, 2023
In this paper we introduce the class of matrix valued asymmetric truncated Hankel operators. By using characterizations of matrix valued asymmetric truncated Toeplitz operators, we characterize matrix valued asymmetric truncated Hankel operators in the case when two involved inner matrices are J-symmetric.

A Proposed Quantum Framework for Low-Complexity Quantum Simulation and Spectrum Estimation of Hankel-Patterned Systems

open access: yesIEEE Transactions on Quantum Engineering, 2023
The structured matrix completion problem (SMCP) is ubiquitous in several signal processing applications. In this article, we consider a fixed pattern, namely, the Hankel-structure for the SMCP under quantum formalism. By exploiting its structure, a lower-

A partial sum of singular‐value‐based reconstruction method for non‐uniformly sampled NMR spectroscopy

open access: yesIET Signal Processing, 2021
The nuclear magnetic resonance (NMR) spectroscopy has fruitful applications in chemistry, biology and life sciences, but suffers from long acquisition time.

Simultaneous reconstruction and denoising for DAS-VSP seismic data by RRU-net

open access: yesFrontiers in Earth Science, 2023
Distributed acoustic sensing in vertical seismic profile (DAS-VSP) acquisition plays an important role in reservoir monitoring. But the field data can be noisy and associated with missing traces which affects the seismic imaging and geological ...

Analytical solutions to some generalized and polynomial eigenvalue problems

open access: yesSpecial Matrices, 2021
It is well-known that the finite difference discretization of the Laplacian eigenvalue problem −Δu = λu leads to a matrix eigenvalue problem (EVP) Ax =λx where the matrix A is Toeplitz-plus-Hankel.
