Abstract: To obtain high-quality plastic products, an industrial volume-pulsatile injection-molding (VPIM) machine is developed to achieve high screw displacement amplitude. However, it is difficult for engineers to optimize vibration ...

Abstract: Microaerial vehicles (MAVs) face limited flight times, which adversely impacts their efficacy for scenarios such as first response and disaster recovery, where it might be useful to deploy persistent radio relays and ...

Abstract: Magnetic compression based anastomoses use magnetic force to necrose tissue between two magnets to create an anastomosis. Nickelplated neodymium–iron–boron magnets are used in our study. The compression pressure between ...

Abstract: We present a hand specialized for climbing unstructured rocky surfaces. Articulated fingers achieve grasps commonly used by human climbers. The gripping surfaces are equipped with dense arrays of spines that engage with ...
