Automatic identification of redundant gears in planetary gear trains

Mathematical and Computer Modelling, 1994
Redundant gears should be eliminated in the design of automatic transmissions in order to reduce inertial power loss and manufacturing costs. The purpose of this paper is to present a computerized method for the identification of redundant gears in planetary gear trains.

Collaborating in future states—Contextual instability, paradigmatic remaking, and public policy

Australian Journal of Public Administration, EarlyView.
Abstract Collaboration is ubiquitous in public policy life, with its presence and profile determined by prevailing governance conditions. Commitments to globalisation and marketisation in the latter part of the 20th century marked the onset of an era defined by collaboration, between and across tiers and spheres of government, with non‐state actors ...

Joint Modeling of Planetary Gear Train and Bearings of Wind Turbines for Vibration Analysis of Planetary Bearing Outer Ring Looseness Fault

Energies
The planetary bearing looseness fault can cause the planetary gear train to fail. Conventional modeling methods do not consider complex component-coupling relationships for fault feature analysis.

For an inviting anthropology Pour une anthropologie accueillante

Journal of the Royal Anthropological Institute, EarlyView.
Anthropologists have recently become inspired, captivated even, by the practices of the arts, design, and architecture in efforts to renew anthropology's modes of engagement and understandings of its relevance, particularly affecting how we approach ethnographic fieldwork.
