Design optimization analysis of an anti-backlash geared servo system using a mechanical resonance simulation and experiment [PDF]
In many mechatronic systems, gear transmission chains are often used to transmit motion and power between motors and loads, especially for light, small but large torque output systems.

A Comprehensive Compensation Method for High-speed Gear Pumps Without the Cavitation Phenomenon
In order to improve the cavitation performance under high-speed for external gear pumps, a comprehensive compensation method with the small backlash, innovative annulus relief-groove and increasing inlet oil-pressure is proposed.

Postscript: Feminist Legal Theory in the 21st Century
This editorial takes the form of a short postscript to a special issue of Laws published in 2019–20. It shows how feminist legal theory (FLT), a corollary of second wave feminism, was initially embraced by law schools but soon subjected to a backlash ...
