Design and Analysis of Continuously Variable Transmission based on Nested Structure
Jixie chuandong, 2022 At present，robot joint reducers are all constant transmission ratio，which makes it difficult for the motor to reach peak efficiency. Based on the nested structure，a compact continuously variable transmission （CVT） for robots is proposed，which can ...

An Approach to Multicriteria Optimization of the Three-Stage Planetary Gear Train
MachinesPlanetary gear trains offer numerous advantages over traditional gear systems, including high efficiency, the ability to handle large torque loads, and significant reductions in mass and size for the same torque capacity.

neonSoilFlux: An R package for continuous sensor‐based estimation of soil CO2 fluxes
Methods in Ecology and Evolution, EarlyView.Abstract Accurate quantification of soil carbon fluxes is essential to reduce uncertainty in estimates of the terrestrial carbon sink. However, these fluxes vary over time and across ecosystem types and so, it can be difficult to estimate them accurately across large scales.

(Un)threading Rhythms: On Affect and Vibe in a Rave
Anthropology of Consciousness, EarlyView.ABSTRACT In Toronto, raves arise across large nightclubs, DIY venues and outdoors, despite changing regulations that have further arranged and narrowed their possibility in the past 4 years. Following a rave in Toronto, this work explores ways that potentialities and affects emerge in a single night, through my entry of taking part in dancing and ...
