Eigenvalue and eigenvector approximate analysis for repeated eigenvalue problems

AIAA Journal, 1992
The objectives are to present a method for eigenvalue and eigenvector approximate analysis in the presence of repeated eigenvalues and to present an alternate method for the eigenvector sensitivity equations. The method developed for approximate analysis involves a reparametrization of the multivariable structural eigenvalue problems in terms of a ...

Random Eigenvalue Problems in Structural Analysis

AIAA Journal, 1972
A computerized Monte Carlo simulation is presented for calculating the statistical properties of the eigenvalues of a spring supported beam-column. The spring supports and axial force are treated as random variables ; the distributions of material and geometric properties are considered to be correlated homogeneous random functions.

SLIP-WEAKENING FRICTION INSTABILITIES: EIGENVALUE ANALYSIS

Mathematical Models and Methods in Applied Sciences, 2004
We consider the evolution problem for the wave equation with nonlinear boundary conditions, modeling the anti-plane shearing on a system of finite faults under a slip-dependent friction in a linear elastic continuum. The associated eigenvalue problem is studied for bounded and unbounded domains. Recent studies showed that this eigenvalue problem plays

Eigenvalue analysis of synchronous machines

IEEE Transactions on Power Apparatus and Systems, 1975
This paper presents a numerical approach useful for determining the modes of transient response of a synchronous generator. The approach is based upon the Floquet theory of periodic time-variable systems. A computer algorithm for system transition matrix eigenvalue analysis is described and applied to a three-phase synchronous machine.

Nonsmooth analysis of eigenvalues

Mathematical Programming, 1999
Subdifferentials (limiting Fréchet, Clarke) of the composition \(f\circ \lambda \) of extended real valued permutation invariant functions \(f\) and the eigenvalue vector function \(\lambda \) of a symmetric matrix \(X\) are calculated using the transformation to principles axes.

Matrix methods for bare resonator eigenvalue analysis

Applied Optics, 1980
Bare resonator eigenvalues have traditionally been calculated using Fox and Li iterative techniques or the Prony method presented by Siegman and Miller. A theoretical framework for bare resonator eigenvalue analysis is presented. Several new methods are given and compared with the Prony method.

Standard eigenvalue analysis by boundary‐element method

Communications in Numerical Methods in Engineering, 1993
AbstractA method for analysing eigenvalues of the Helmholtz equation using a standard existing subroutine for eigenvalue determination is developed in this paper. It is based on the boundary integral equation formulation known as the multiple reciprocity method (MRM).

CHANGE: Cardiac Health Analysis Using Graph Eigenvalues

2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018
Coronary Artery Disease (CAD) is an important problem in cardiac health and is a leading cause of human mortality. Prior arts have shown that features extracted from non-invasive Photoplethysmogram (PPG) signal are effective in classifying CAD. In this paper, we represent cardiac health as a graph (CHG) in order to exploit the dependencies of PPG ...
