A branch and bound methodology for matrix polytope stability problems arising in power systems
Robust matrix of power system the linearized dynamics linear system model robust stability
2015/8/12
This paper proposes a formulation to provide necessary and sufficient conditions for robust stability of a family of matrices modeling linearized power system dynamics. A construction for transforming...
Existence and uniqueness of optimal matrix scalings
diagonal similarity scalings scaled singular value minimization irreducible matrices
2015/8/12
We show that the set of diagonal similarity scalings that minimize the scaled singular value of a matrix is nonempty and bounded if and only if the matrix that is being scaled is irreducible. For an i...
Degree bounds for polynomial verification of the matrix cube
matrix cube polynomial verification
2015/6/19
In this paper we consider the problem of how to computationally test whether a matrix inequality is positive semidefinite on a semialgebraic set. We propose a family of sufficient conditions using the...
Time-Delayed Decentralized H-Infinity Controller Design for Civil Structures: a Homotopy Method Through Linear Matrix Inequalities
Civil Structures Controller Design
2015/6/19
Traditional structural feedback control systems are centralized systems, whose applications to large scale structures encounter a number of practical difficulties in terms of system reliability, cost,...
Robust Global Motion Estimation with Matrix Completion
Camera orientation Structure from motion Epipolar geometry Block adjustment
2014/7/30
In this paper we address the problem of estimating the attitudes and positions of a set of cameras in an external coordinate system. Starting from a conventional global structure-from-motion pipeline,...
The Bethe Permanent of a Non-Negative Matrix
Bethe approximation Bethe permanent graph cover partition function perfect matching permanent sumproduct algorithm
2011/9/16
Abstract: It has recently been observed that the permanent of a non-negative square matrix, i.e., of a square matrix containing only non-negative real entries, can very well be approximated by solving...
An Interpretation of the Moore-Penrose Generalized Inverse of a Singular Fisher Information Matrix
Cramer-Rao bound constrained parameters singular Fisher information matrix
2011/9/1
Abstract: An interpretation of the Moore-Penrose generalized inverse of a singular Fisher information matrix (FIM) is presented in this paper, from the perspective of Cramer-Rao bound (CRB). CRB is a ...
Decoding of Matrix-Product Codes
Linear Codes Matrix-Product Codes Decoding Algorithm Minimum Distance
2011/8/30
Abstract: We propose a decoding algorithm for the $(u\mid u+v)$-construction that decodes up to half of the minimum distance of the linear code. We extend this algorithm for a class of matrix-product ...
Google matrix and Ulam networks of intermittency maps
Google matrix Ulam networks intermittency maps
2010/4/8
We study the properties of the Google matrix of an Ulam network generated by intermittency maps. This network is created by the Ulam method which gives a matrix approximant for the Perron-Frobenius op...
