Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.Bolted joint structures are critical fastening components across various engineering applications, and the ability to monitor their contact status is crucial for effective structural health monitoring (SHM). The acoustic emission (AE) technique combined with deep learning (DL) methods has been extensively applied in bolt looseness monitoring.

Civil Engineering Design, Volume 7, Issue 4, Page 147-168, December 2025.Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize

Unitary automorphisms of the space of Toeplitz-plus-Hankel matrices
Special Matrices, 2015 Our motivation was a paper of 1991 indicating three special unitary matrices that map Hermitian Toeplitz matrices by similarity into real Toeplitz-plus-Hankel matrices.

Catalan Transform of k-Balancing Sequences
International Journal of Mathematics and Mathematical Sciences, 2021 In this work, the Catalan transformation (CT) of k-balancing sequences, Bk,nn≥0, is introduced. Furthermore, the obtained Catalan transformation CBk,nn≥0 was shown as the product of lower triangular matrices called Catalan matrices and the matrix of k ...

Numerical Linear Algebra with Applications, Volume 32, Issue 6, December 2025.ABSTRACT In this work, we propose a novel preconditioned minimal residual method for a class of real, nonsymmetric multilevel block Toeplitz systems, which generalizes an ideal preconditioner established in [J. Pestana. Preconditioners for symmetrized Toeplitz and multilevel Toeplitz matrices. SIAM Journal on Matrix Analysis and Applications, 40(3):870–

Polynomial computation of Hankel singular values [PDF]
, 1992 A revised and improved version of a polynomial algorithm is presented. It was published by N.J. Young (1990) for the computation of the singular values and vectors of the Hankel operator defined by a linear time-invariant system with a rotational ...

Low‐Energy Atomic Scattering: S‐Wave Relation Between the Interaction Potential and the Phase Shift
Annalen der Physik, Volume 537, Issue 11, November 2025.The validity of the on‐shell approximation for s‐wave scattering is examined across one, two, and three dimensions using exactly solvable model interaction potentials. By comparing exact and approximate s‐wave components of the interaction potential, the analysis reveals that the approximation improves with increasing momentum and decreasing ...

$ L_2/L_1 $ induced norm and Hankel norm analysis in sampled-data systems
AIMS MathematicsThis paper is concerned with the $ L_2/L_1 $ induced and Hankel norms of sampled-data systems. In defining the Hankel norm, the $ h $-periodicity of the input-output relation of sampled-data systems is taken into account, where $ h $ denotes the sampling

A Simplified Modeling Framework of Higher‐Order Topological States in Elastic Metaplates
Small Structures, Volume 6, Issue 11, November 2025.A simplified elastic metaplate using periodically arranged plate‐pillar clusters (PPCs) is constructed. By integrating dual‐topology PPCs and developing a mass‐spring model with multiple scattering theory, theoretical modeling of higher‐order topological corner states in elastic wave systems, validated through simulations and experiments, is enabled ...
