THE KINEMATIC ANALYSIS OF RAVIGNEAUX PLANETARY GEAR SET

, 2016
The power transfer is an irreplaceable partof every industry. Due to technology improvement,the mechanisms are working with less and lesslosses, but their constructions are becoming morecomplex. This essay is dedicated to the planetarygear sets, with a focus on the Ravigneaux planetarygear set which represents, in fact, improved versionof Simpson’s ...

Bridging Global Sustainability Objectives With Corporate Reporting Standards: Sustainable Development Goals Meet European Sustainability Reporting Standards

Sustainable Development, EarlyView.
ABSTRACT Given the complexity of the Sustainable Development Goals (SDGs), aligning corporate sustainability with them can be challenging. Drawing on systems thinking, this study examines how the European Sustainability Reporting Standards (ESRS) align with the SDGs and bridge macro‐level global goals with firm‐level metrics.

RETRACE Project: How to Enhance Resilience to Climate Risks in Pacific and Arctic Indigenous Communities?

Sustainable Development, EarlyView.
ABSTRACT Risk management has evolved to analyze risks in a systemic way, integrating local knowledge with the abstract concept of resilience, which is now an imperative for vulnerable and exposed communities. However, existing decision‐support tools are mainly focused on technical‐functional aspects and, although based on rigorous and scientific ...

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

Symbolic 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
