Abstract
The detection of structural changes in time series from industrial processes monitoring
is of great interest. We investigate the limits and possibilities of two recently
developed methods, one for the off -line detection of changed volatilities [Wied et al.,
2011] and one for the on-line detection of changes in the course of the time series
[Borowski and Fried, 2011]. The investigation is carried out on several time series
from thermal spraying processes. The processes are deliberately manipulated to
produce structural changes at known time points.
