An Adaptive Control Approach for Discrete-Time Systems with Unknown Backlash at the Input
In this paper, we focus on the development of an adaptive control scheme for systems with unknown backlash. More specifically, we propose a discrete timeadaptive backlash inverse based controller for plants that have a known line arpart and an unknown ...

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.

A Tale of Two Tariff Commissions and One Dubious 'Globalization Backlash' [PDF]
During much of the previous era of globalization, from the 1860s until the First World War, U. S. tariffs were surprisingly high. Present-day economic historians have suggested that U. S.
