Theory and Methods in Determining the Eigenvalues and Eigenvectors of a MatrixWaldon, Jerry Herschel 08 1900 (has links)
In the numerous problems of matrix algebra, one finds the problem of determining the eigenvalues of eigenvectors of a matrix quite frequently. The theory and methods leading to the solution of the eigenvalue and eigenvector problem are of considerable interest. The relation between vector spaces, matrices, eigenvalues, and eigenvectors is to be considered in this chapter, with particular concentration directed toward the eigenvalues and eigenvectors shall be developed in the following chapters with detailed examples of the methods.

A New Adaptive Array of Vibration SensorsSumali, Hartono 05 August 1997 (has links)
The sensing technique described in this dissertation produces modal coordinates for monitoring and active control of structural vibration. The sensor array is constructed from strainsensing segments. The segment outputs are transformed into modal coordinates by a sensor gain matrix.
An adaptive algorithm for computing the sensor gain matrix with minimal knowledge of the structure's modal properties is proposed. It is shown that the sensor gain matrix is the modal matrix of the segment output correlation matrix. This modal matrix is computed using new algorithms based on Jacobi rotations. The procedure is relatively simple and can be performed gradually to keep computation requirements low.
The sensor system can also identify the mode shapes of the structure in real time using Lagrange polynomial interpolation formula.
An experiment is done with an array of piezoelectric polyvinylidene fluoride (PVDF) film segments on a beam to obtain the segment outputs. The results from the experiment are used to verify a computer simulation routine. Then a series of simulations are done to test the adaptive modal sensing algorithms. Simulation results verify that the sensor gain matrix obtained by the adaptive algorithm transforms the segment outputs into modal coordinates. / Ph. D.

On the Study of the Aizawa SystemUnknown Date (has links)
In this report we study the Aizawa field by first computing a Taylor series
expansion for the solution of an initial value problem. We then look for singularities
(equilibrium points) of the field and plot the set of solutions which lie in the linear
subspace spanned by the eigenvectors. Finally, we use the Parameterization Method
to compute one and two dimensional stable and unstable manifolds of equilibria for
the system. / Includes bibliography. / Thesis (M.S.)Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection
