Abstract: This paper proposes a new feature extraction method based on Independent Component Analysis (ICA) and reconstructed phase space. The ICA-based phase space feature unifies the system dynamics ...

Abstract: Many modern engineering systems use multiple sensors for monitoring, diagnosis and control. Some of these sensors contain not only time domain and frequency domain information, but also valuable ...

Abstract: Invented more than 200 years ago, the automatic winding device of mechanical watch movement is one of the most successful energy harvesting devices. It harvests the kinematical energy from body ...
