Gesture recognition method based on a single-channel sEMG envelope signal

EURASIP Journal on Wireless Communications and Networking, 2018
In the past, investigators tend to use multi-channel surface electromyography (sEMG) signal acquisition devices to improve the recognition accuracy for the study of gesture recognition systems based on sEMG.

Probing molecular dynamics at the nanoscale via an individual paramagnetic center

, 2015
Understanding the dynamics of molecules adsorbed to surfaces or confined to small volumes is a matter of increasing scientific and technological importance. Here, we demonstrate a pulse protocol using individual paramagnetic nitrogen vacancy (NV) centers

An Efficient Translational Motion Compensation Approach for ISAR Imaging of Rapidly Spinning Targets

Remote Sensing, 2022
For inverse synthetic aperture radar (ISAR) imaging of rapidly spinning targets, the large migration through range cells (MTRC) results in weak coherence between adjacent echoes, which makes the conventional envelope alignment method unable to be applied.

Study of the Convective Heat Transfer Coefficient of Different Building Envelope Exterior Surfaces

Buildings, 2022
Convective heat transfer on the exterior surface of the building envelope is an important component for building energy consumption. The calculation of energy consumption depends on the convective heat transfer coefficient (CHTC) of the exterior surface ...
