Tricomi Continuants

open access: yesMathematics
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.

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

open access: yes
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 ...

Decentralised and Centralised Fixed Structure H∞ Robust Loop Shaping for the MIMO Microsurgical Manipulation Based on PSOGSA

open access: yesIET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This paper presents a robust H∞ decentralised and centralised control approach for a microsurgical manipulator using Particle Swarm Optimisation and Gravitational Search Algorithm (PSOGSA). The proposed fixed‐structure Proportional‐Integral‐Derivative (PID)‐based controllers address implementation challenges of conventional high‐order H∞ controllers ...

Advances in Characterising Dielectric Materials at Microwave Frequencies Using Circular Open Waveguides

open access: yesElectronics Letters, Volume 62, Issue 1, January/December 2026.
The dielectric characterisation method using an open circular waveguide, while widely recognised for its advantages, faces key limitations such as multiple solutions during data extraction and an imperfect calibration process. Our research introduces solutions that ensure convergence toward a unique result and enhance calibration accuracy, particularly

SVD Algorithm in the Application of the MIMO System Model Order Reduction

open access: yesJournal of Harbin University of Science and Technology, 2017
For linear time invariant high-order system calculation and analysis model is difficult to directly,so we need to study on reduction of the model According to the basic theory of model order reduction Lyapunov equation model order solution to linear time

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

open access: yes, 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 ...

Super resolution DOA estimation with incomplete single snapshot data via matrix completion and compress sensing

open access: yesMATEC Web of Conferences, 2018
A method of super resolution DOA estimation with incomplete single snapshot data via matrix completion (MC) and compress sensing (CS) is presented. First, the incomplete single snapshot data is reshaped into a low-rank Hankel matrix form and the complete

Analysis of cardiosignals cohesion based on Hankel matrix

open access: yes, 2008
A big part of heart disease diagnostics criteria is collected by registration and analysis of cardio signals that show electric heart activity disturbance (ECG) and hemodynamic and mechanic activity changes as impedance cardiograms (ICG) and seismocardiograms (SCG).
