Experimental Study on the Influence of Load-Equalizing Devices on Planet Loads in a Planetary Gear Set

open access: yesEngineering Proceedings
The uneven load distribution between the planets in planetary gear trains has found multiple solutions including high manufacturing precision, targeted compliance or kinematic mobility of the components of the gear train.

Coupled vibrations of a drive system during automatic transmission

open access: yesAdvances in Mechanical Engineering, 2019
Coupled vibrations are difficult to overcome in automatic transmission with mixed gear trains. In this study, a mathematical model for the bending–torsional–axial–oscillation vibrations of mixed gear trains with parallel-axis gear pairs, a clutch ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

open access: yesSymbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Den attendance by Arctic foxes experiencing 10 years of increasing tourism

open access: yesWildlife Biology, EarlyView.
Wildlife tourism is a growing industry, and an increasing number of people seek to observe and interact with wild animals in their natural surroundings. In Iceland, the native Arctic fox Vulpes lagopus is widespread and has been under heavy hunting pressure for centuries.

AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,

DESIGN FOR A BI-PLANETARY GEAR TRAIN

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2016
The article presents the design for a bi-planetary gear train. The project description is supplemented with calculations of kinematics, statics and meshing efficiency of the gear wheels included in the gear train. Excluded are calculations of strength and geometry of gears, shaft and rolling bearing, since they are similar to classical calculations for

Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

open access: yesConservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.
