Abstract: Unidirectional acoustic transmission is acquired in a one-dimensional graded phononic crystal. The distinct feature of the present design is that waves can propagate unidirectionally at a certain frequency from the left ...

Abstract: Abstract. With the widespread adoption of electric vehicles, early detection of micro-short circuits and aging in lithium-ion batteries has become a critical issue in safety management. To address the problem of insufficient ...

Abstract: In this paper, we present an integrated robotic arm with a flexible endoscope for laparoscopy. The endoscope holder is built to mimic a human operator that reacts to the surgeon's push while maintaining both the incision ...
