Robust normalization and guaranteed cost control for a class of uncertain singular Markovian jump systems via hybrid impulsive control [PDF]

open access: yes, 2013
This paper investigates the problem of robust normalization and guaranteed cost control for a class of uncertain singular Markovian jump systems. The uncertainties exhibit in both system matrices and transition rate matrix of the Markovian chain.

On a Matrix Inequality Related to the Distillability Problem

open access: yesEntropy, 2018
We investigate the distillability problem in quantum information in ℂ d ⊗ ℂ d . One case of the problem has been reduced to proving a matrix inequality when d = 4 .

Algorithm with Patterned Singular Value Approach for Highly Reliable Autonomous Star Identification

open access: yesSensors, 2020
In the work reported in this paper, a lost-in-space star pattern identification algorithm for agile spacecraft was studied. Generally, the operation of a star tracker is known to exhibit serious degradation or even failure during fast attitude maneuvers.

The smallest singular value of certain Toeplitz-related parametric triangular matrices

open access: yesSpecial Matrices, 2021
Let L be the infinite lower triangular Toeplitz matrix with first column (µ, a1, a2, ..., ap, a1, ..., ap, ...)T and let D be the infinite diagonal matrix whose entries are 1, 2, 3, . . . Let A := L + D be the sum of these two matrices.

Multiplicity and uniqueness results for the singular nonlocal boundary value problem involving nonlinear integral conditions [PDF]

open access: yes, 2014
In this paper, using fixed point index and the mixed monotone technique, we present some multiplicity and uniqueness results for the singular nonlocal boundary value problems involving nonlinear integral conditions.

Nonlinear cross Gramians and gradient systems [PDF]

open access: yes, 2007
We study the notion of cross Gramians for non-linear gradient systems, using the characterization in terms of prolongation and gradient extension associated to the system.

Watermark Based on Singular Value Decomposition

open access: yesمجلة بغداد للعلوم, 2023
Watermarking operation can be defined as a process of embedding special wanted and reversible information in important secure files to protect the ownership or information of the wanted cover file based on the proposed singular value decomposition (SVD)

A geometrical formulation of the μ-lower bound problem [PDF]

open access: yes, 2009
A new problem formulation for the structured singular value μ in the case of purely real (possibly repeated) uncertainties is presented. The approach is based on a geometrical interpretation of the singularity constraint arising in the μ lower

Singular Value Decomposition of Spatial Matrices

open access: yesСовременные информационные технологии и IT-образование, 2022
Singular value decomposition is a basic building block which is used in solution of many different problems. In cases when dimensionality of a problem exceeds two, a generalization of a singular value decomposition – tensor decompositions – are used ...
