Hankel Tensors: Associated Hankel Matrices and Vandermonde Decomposition

, 2014
Hankel tensors arise from applications such as signal processing. In this paper, we make an initial study on Hankel tensors. For each Hankel tensor, we associate it with a Hankel matrix and a higher order two-dimensional symmetric tensor, which we call ...

Identification of random coefficient latent utility models

Quantitative Economics, Volume 16, Issue 4, Page 1223-1265, November 2025.
This paper provides nonparametric identification results for random coefficient distributions in perturbed utility models. We cover discrete choice and models of multiple purchases. We establish identification using variation in mean quantities. The results apply even when an analyst observes only aggregate demands but not whether goods are chosen ...

The use of the QR factorization in the partial realization problem [PDF]

The use of the QR factorization of the Hankel matrix in solving the partial realization problem is analyzed. Straightforward use of the QR factorization results in a realization scheme that possesses all of the computational advantages of Rissanen's ...

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 10, Page 2119-2142, October 2025.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Semi‐Automated Operational Modal Analysis With Fuzzy Clustering for Structural System Identification

Engineering Reports, Volume 7, Issue 10, October 2025.
This study presents a semi‐automated operational modal analysis method combining fuzzy clustering and similarity filtering for structural identification. Applied to a six‐story RC building in Iran, the approach achieves < 5% frequency error, validated via Modal Complexity Factor, advancing automation and reliability in structural health monitoring ...

Tricomi Continuants

Mathematics
In this paper, we introduce and study the Tricomi continuants, a family of tridiagonal determinants forming a Sheffer sequence closely related to the Tricomi polynomials and the Laguerre polynomials.

Detecting optimality and extracting solutions in polynomial optimization with the truncated GNS construction

, 2017
A basic closed semialgebraic subset of $\mathbb{R}^{n}$ is defined by simultaneous polynomial inequalities $p_{1}\geq 0,\ldots,p_{m}\geq 0$. We consider Lasserre's relaxation hierarchy to solve the problem of minimizing a polynomial over such a set ...

INVERTIBILITY PROPERTIES OF MATRIX WIENER‐HOPF PLUS HANKEL INTEGRAL OPERATORS

Mathematical Modelling and Analysis, 2008
We consider matrix Wiener‐Hopf plus Hankel operators acting between Lebesgue spaces on the real line with Fourier symbols presenting some even properties (which in particular include unitary matrix‐valued functions), and also with Fourier symbols which contain sectorial matrices.
