The approximate location of imperfections in an ellipse using the spectral theory

摘要

In the paper, the authors describe the analysis and results of research on the approximate location of a defect with the help of the spectral theory for the area which is a geometrical ellipse. A computer simulation was conducted in Matlab. At the end of the paper, the authors give an example to illustrate the method of determining the areas in which the ellipse may be damaged.
