Resonance-based sparse adaptive variational mode decomposition and its application to the feature extraction of planetary gearboxes.

open access: yesPLoS ONE, 2020
Due to the assumption that the VMD technique is essentially a set of adaptive Wiener filter banks and its performance depends to a large extent on the preset parameter K (the number of decomposition).

Characterization and Selection of Contractile Actuators for Soft Robotics Operating in the Quasistatic Regime

open access: yesAdvanced Intelligent Systems, EarlyView.
We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement
