The Dynamic Characteristic and Hysteresis Effect of an Air Spring [PDF]

open access: yesInternational Journal of Applied Mechanics and Engineering, 2015
In many applications of vibration technology, especially in chassis, air springs present a common alternative to steel spring concepts. A design-independent and therefore universal approach is presented to describe the dynamic characteristic of such ...

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.

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.

Egg-shaped bounding surface model for saturated soft clay

open access: yesYantu gongcheng xuebao, 2020
In order to describe the dynamic characteristics of saturated soft clay under cyclic loading, an egg-shaped one-sided bounding surface model is established.

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 ...

Characteristics of the Dynamic of Mobile Networks [PDF]

open access: yes, 2010
We propose in this paper a novel framework for the study of dynamic mobility networks. We address the characterization of dynamics by proposing an in-depth description and analysis of two real-world data sets. We show in particular that links creation and deletion processes are independent of other graph properties and that such networks exhibit a ...

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.

Dynamic Stability Characteristics of Aircraft and Dynamics of Pilot

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, 2002
Dynamics of pilot was studied quantitatively in relation to the change of dynamic stability characteristics of aircraft. Three pilot conducted bank control on flight simulator which simulate aircraft dynamics with large variety of dutch roll characteristics, and data was acquired.
