Singular value decomposition Geršgorin sets [PDF]
, 2006 In this note, we introduce the singular value decomposition Geršgorin set, ΓSV (A), of an N×N complex matrix A, where N⩽∞. For N finite, the set ΓSV (A) is similar to the standard Geršgorin set, Γ (A), in that it is a union of N closed disks in the ...

Modeling Electromechanical Overcurrent Relays Using Singular Value Decomposition
Journal of Applied Mathematics, 2012 This paper presents a practical and effective novel approach to curve fit electromechanical (EM) overcurrent (OC) relay characteristics. Based on singular value decomposition (SVD), the curves are fitted with equation in state space under modal ...

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices
Advanced Functional Materials, EarlyView.This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Adaptive template-updating strategy based on singular value decomposition
, 2007 The problem of image matching and target tracking based on singular value decomposition (SVD) is discussed. The SVD has robust performance that is invariant to image disturbance and it makes the singular value credible to represent the image as an ...

SINGULAR VALUE DECOMPOSITION IN DIGITAL IMAGE ANALYSIS
Informatika, 2017 The paper describes new properties of the singular matrix decomposition. It is shown that permutation of rows or columns of the matrix or matrix rotation by 90 degrees does not change the set of its singular numbers.

Through-Wall Image Enhancement Based on Singular Value Decomposition
International Journal of Antennas and Propagation, 2012 Singular value decomposition and information theoretic criterion-based image enhancement is proposed for through-wall imaging. The scheme is capable of discriminating target, clutter, and noise subspaces.
