Extracting stationary segments from non-stationary synthetic and cardiac signals
(SPIE, 2014-10-14)
Physiological signals are commonly the result of complex interactions between systems and organs, these interactions lead to signals that exhibit a non-stationary behaviour. For cardiac signals, non-stationary heart rate ...

Comparing non-stationary and irregularly spaced time series
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this paper, we present approximate distributions for the ratio of the cumulative wavelet periodograms considering stationary and non-stationary time series generated from independent Gaussian processes. We also adapt ...

Non stationary demand forecasting based on empirical mode decomposition and support vector machines
(IEEE, 2017)
A company performance strongly depends on its ability of delivering the right quantity of of a given product at the time customers require. Even though some demand forecasting techniques have been developed, they have ...
