Parametric Study of Stochastic Subspace Algorithms in Modal Analysis of Moment‐Resistant Frames [PDF]
Numerical Methods in Civil EngineeringThe Finite Element Model (FEM) derived from the design drawings may not precisely depict the behavior of the actual structure. This is due to various factors, such as construction variations, uncertainties in boundary conditions, discrepancies in ...

An note on the maximization of matrix valued Hankel determinants with application [PDF]
In this note we consider the problem of maximizing the determinant of moment matrices of matrix measures. The maximizing matrix measure can be characterized explicitly by having equal (matrix valued) weights at the zeros of classical (one dimensional ...

Modal parameter identification from output data only
MATEC Web of Conferences, 2015 To identify the modal parameters of a vibrating system from output data only we use a state space model and usually two approaches are considered: the block Hankel matrix and its shifted version and the block observability matrix and its shifted version.

Linear prediction of stationary vector sequences [PDF]
The class of all linear predictors of minimal order for a stationary vector-valued process is specified in terms of linear transformations on the associated Hankel covariance matrix.

Solving Hankel matrix approximation problem using semidefinite programming
Journal of Computational and Applied Mathematics, 2007 The author studies the problem of finding the nearest matrix to a positive semidefinite Hankel matrix in such a way that all the special properties are preserved. In the usual evaluation techniques rounding and truncation limitations result in some of the properties to be lost.

Hankel matrix normalization for robust damage detection
, 2019 In the context of detecting changes in structural systems, multiple vibration-based damage detection methods have been proposed and successfully applied to both mechanical and civil structures over the past years. One of the popular schemes is based on a robust subspace-based residual and enjoys favorable statistical and computational properties, like ...

Matrix Completion-based Range-Doppler Spectrum Estimation for Random Stepped-frequency Radars
Leida xuebaoRandom Stepped Frequency (RSF) radars can achieve high-range resolution with relatively low hardware complexity by synthesizing a wide bandwidth. Moreover, because of the random frequency agility of each pulse, the radars possess robust anti-interference
