Power Transmission Characteristics of the Magnetic Gear Reducer with a Variable Gear Ratio [PDF]

open access: yes한국정밀공학회지, 2019
The gear ratio variable topology of a magnetic gear with an integrated harmonic modulator is analyzed using a magnetic permeance model. A dynamic characteristic equation is derived in consideration of the gear ratio between each layer constituting the ...

Experimental Study of the Influence of Rotor Dynamics on the Temperature Distribution of a Gas Foil Bearing

open access: yesApplied Sciences, 2022
This article presents an experimental study carried out on a rotor operating on two foil bearings. One of the bearings was built in a way to measure the temperature and deformation of the top foil of the foil bearing.

Dynamic and static angry faces influence time perception differently—Evidence from ERPs

open access: yesFrontiers in Neuroscience, 2023
The dynamic characteristics of facial expressions might affect time perception. Compared with static emotional faces, dynamic emotional faces are more intense, have higher ecological validity, and contain time series information, which may lead to time ...

Analysis of Dynamic Characteristics of an Ultra-Large Semi-Submersible Floating Wind Turbine

open access: yesJournal of Marine Science and Engineering, 2019
An initial design of the platform for the moderate water depth (100 m) is performed by upscaling of an existing 5 MW braceless semi-submersible platform design to support the DTU (Danish University of Science and Technology) 10 MW wind turbine.

Dynamic characteristics of oxygen consumption [PDF]

open access: yesBioMedical Engineering OnLine, 2018
Previous studies have indicated that oxygen uptake ([Formula: see text]) is one of the most accurate indices for assessing the cardiorespiratory response to exercise. In most existing studies, the response of [Formula: see text] is often roughly modelled as a first-order system due to the inadequate stimulation and low signal to noise ratio.

A characteristic dynamic mode decomposition [PDF]

open access: yesTheoretical and Computational Fluid Dynamics, 2019
Temporal or spatial structures are readily extracted from complex data by modal decompositions like Proper Orthogonal Decomposition (POD) or Dynamic Mode Decomposition (DMD). Subspaces of such decompositions serve as reduced order models and define either spatial structures in time or temporal structures in space.

Nonparametric Tests for Conditional Symmetry in Dynamic Models [PDF]

open access: yes, 2007
This article proposes omnibus tests for conditional symmetry around a parametric function in a dynamic context. Conditional moments may not exist or may depend on the explanatory variables.
