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]
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 ...

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 ...

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
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

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 ...

RIS-Based DOA Estimation for Communication-Assisted Sensing Systems Under Hardware Impairments
Reconfigurable intelligent surface (RIS)-based localization has received significant attention in wireless communication systems due to its potential for enabling non-line-of-sight (NLoS) wireless sensing.

Analysis of cardiosignals cohesion based on Hankel matrix
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).
