Machine vision–based measurement approach for transverse vibrations of moving hoisting vertical ropes in mine hoists using edge location [PDF]
Measurement and Control, 2019 Hoisting vertical rope is a continuum of one-dimensional movement during operation of hoist, and there are no appropriate ways to measure its vibration displacement at present. In this paper, a non-contact and unmarked machine vision measurement method is proposed for measuring the transverse vibration displacement of hoisting vertical ropes. First, we

British Journal of Industrial Relations, EarlyView.ABSTRACT Works councils in Germany possess substantial institutional resources to protect workers' interests. Yet little is known about how these resources are mobilised in practice and why similar outcomes may emerge through different pathways. Drawing on two German firms acquired by Chinese state‐owned enterprises, this study examines how works ...

The specifics of non‐routine task changes: A granular approach
Contemporary Economic Policy, EarlyView.Abstract This paper estimates granular specific non‐routine tasks and examines employment reallocation across those tasks in the United States. Employment shifts into decision‐making, technology, and information‐related tasks account for 90% of high‐wage employment growth.
