Fixed‐time stabilisation of boundary controlled linear parabolic distributed parameter systems with space‐dependent reactivity

IET Control Theory & Applications, 2021
The problems of state feedback and output feedback for fixed‐time stabilisation of a linear parabolic distributed parameter system with space‐dependent reactivity are considered by means of continuous backstepping approach and Lyapunov method. First, the

Robust State Feedback Control With D-Admissible Assurance for Descriptor Systems Subjected to Perturbed Derivative Matrix

IEEE Access
This work mainly addresses the state feedback control with D-admissible assurance for descriptor systems subjected to perturbed derivative and systems’ matrices simultaneously. By the linear matrix inequality (LMI) and matrix algebra manipulation,

Correlated dynamics of immune network and sl(3, R) symmetry algebra

Computational and Mathematical Biophysics
We observed the existence of periodic orbits in immune network under transitive solvable Lie algebra. In this article, we focus to develop condition of maximal Lie algebra for immune network model and use that condition to construct a vector field of ...

The numerical linear algebra of weights. Part I: from the spectral analysis to conditioning and preconditioning in the one-dimensional Laplacian case

BIT Numerical Mathematics
Abstract Weights are geometrical degrees of freedom that allow to generalize Lagrangian finite elements. They are defined through integrals over specific supports, well understood in terms of differential forms and integration, and lie within the framework of finite element exterior calculus. We adopt this formalism with the target of

Distribution results for a special class of matrix sequences: joining approximation theory and asymptotic linear algebra. ETNA - Electronic Transactions on Numerical Analysis

, 2022
In a recent paper, Lubinsky proved eigenvalue distribution results for a class of Hankel matrix sequences arising in several applications, ranging from Padé approximation to orthogonal polynomials and complex analysis. The results appeared in Linear Algebra and its Applications, and indeed many of the statements, whose origin belongs to the field of ...

Numerical linear algebra and data analysis in large dimensions using tensor format

, 2022
L'objectif de ce travail est d'établir quelles propriétés théoriques des techniques d'algèbre linéaire classique développées dans deux contextes différents, que sont l'algèbre linéaire numérique et l'analyse de données, sont préservées et lesquelles sont perdues, une fois qu'elles sont étendues aux tenseurs grâce à des algorithmes de compression ...

Applications of numerical linear algebra to protein structural analysis: the case of methionine-aromatic motifs

, 2018
Linear algebraic algorithms uncovered a preponderance of protein methionine residues interacting with two or more aromatic residues. The average geometric relationship between transition metals and methionine-aromatic interactions in PDB crystal structures was assessed with a nearest neighbours-like algorithm (“Met-aromatic”) developed for finding and ...

Identification of dynamic systems, theory and formulation [PDF]

The problem of estimating parameters of dynamic systems is addressed in order to present the theoretical basis of system identification and parameter estimation in a manner that is complete and rigorous, yet understandable with minimal prerequisites ...
