AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system
CAAI Transactions on Intelligence Technology, EarlyView.Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Detection of Regenerative Chatter Vibrations of Turning Workpiece.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1993 In this paper, we propose a new method of detecting regenerative chatter of turning workpiece by using spectrum of vibration of the workpiece. Characteristics of vibrations of the workpiece during cutting was investigated first, and then algorithm of detection was thought out from the investigated results.

An effective investigation of chatter prediction system on Al6061 alloy in an end milling process
Journal of Engineering and Applied ScienceVisual examination of the surface topography, in conjunction with the other sensors, may confirm the existence of chatter. Online chatter detection during real machining operations is possible with the use of sensors, and the presence of noise in their ...

Propagation of sound through the Earth's atmosphere. 1: Measurement of sound absorption in the air: 2: Measurement of ground impedance [PDF]
Parts were fabricated for the acoustic ground impedance meter and the instrument was tested. A rubber hose was used to connect the resonator neck to the chamber in order to suppress vibration from the volume velocity source which caused chatter.

Public Inquiries and UK Press Regulation: A Case of ‘Fading into Forgetfulness’?
The Political Quarterly, EarlyView.Abstract Why were the proposals for reform of UK press regulation made by Lord Leveson in 2012 not implemented in full, despite popular and parliamentary support for the report's recommendations, and despite the creation of the legal framework for the reformed system of regulation?
