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 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.

Experimental determination of the dynamic characteristics of the vibrations damper

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2015
One type of object modeling — physical modeling — plays an important role in modern scientific researches. This type of modeling is carried out on the existing laboratory equipment and experimental samples of a real object, which in some way reflects the
