Single-phase earth-fault perception and location method for active distribution networks based on linear eigenvalue statistics

open access: yesFrontiers in Energy Research
To address the difficulty in accurately detecting and locating single-phase-to-ground faults in active distribution networks under random fluctuations of distributed energy resources and disturbances, this paper proposes a fault sensing and section ...

Feedback torque generation in human eigenvector coordinate

open access: yes, 2007
Introduction:We formulated a hypothesis that torque generation could be described by independent eigenvector control. Methods:Human postural modalities, stereotyped responses,were obtained from the eigenvectors, and modal control input was determined by ...

Fractional Active Contour Model with Adaptive Hessian Weighting for Mammogram Segmentation

open access: yesJournal of Medical Signals and Sensors
Background: Accurate segmentation of breast masses in mammographic images is a crucial step in computer-aided diagnosis (CAD) systems. However, mammograms are often affected by noise, low contrast, weak boundaries, and intensity inhomogeneity, which ...

Clustering Variable Length Sequences by

open access: yes, 2004
We present a novel clustering method using HMM parameter space and eigenvector decomposition. Unlike the existing methods, our algorithm can cluster both constant and variable length sequences without requiring normalization of data.

Graph partitioning by Eigenvectors

open access: yesLinear Algebra and its Applications, 1988
Given a graph G on n vertices and \(z\in R^ n\), we say that a vertex of G is positive, nonnegative, null, etc. if the corresponding entry of z has that property. For z such that Az\(\geq \alpha z\) (A is the adjacency matrix of G) the number of components of the subgraph induced by positive vertices is bounded.

Characteristic Polynomial and Eigenproblem of Triangular Matrix over Interval Min-Plus Algebra

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika)
A min-plus algebra is a linear algebra over the semiring R_ε', equipped with the operations “"⊕'=min" ” and “⊗=+”. In min-plus algebra, there is the concept of characteristic polynomial obtained from permanent of matrix.

The eigenvectors of a combinatorial matrix

open access: yesCommunications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2011
In this paper, we derive the eigenvectors of a combinatorial matrix whose eigenvalues studied by Kilic and Stanica. We follow the method of Cooper and Melham since they considered the special case of this matrix.

Eigenvector radiosity

open access: yes, 2001
Radiative flux transfer between Lambertian surfaces can be described in terms of linear resistive networks with voltage sources. This thesis examines how these "radiative transfer networks" provide a physical interpretation for the eigenvalues and ...
