Establishing Direct Phenomenological Connections between Fluid and Structure by the Koopman-Linearly-Time-Invariant Analysis
Cruz Y. Li, Zengshun Chen, Tim K. T. Tse +4
In this work, we introduce a novel data-driven formulation, the Koopman-Linearly-Time-Invariant (Koopman-LTI) analysis, for analyzing Fluid-Structure Interactions (FSI). An impleme…
The Linear-Time-Invariance Notion of the Koopman Analysis-Part 2: Physical Interpretations of Invariant Koopman Modes and Phenomenological Revelations
Cruz Y. Li, Zengshun Chen, Tim K. T. Tse +4
This serial work presents a Linear-Time-Invariance (LTI) notion to the Koopman analysis, finding consistent and physically meaningful Koopman modes and addressing a long-standing p…
The Linear-Time-Invariance Notion of the Koopman Analysis-Part 1: The Architecture, Practical Rendering on the Prism Wake, and Fluid-Structure Association
Cruz Y. Li, Zengshun Chen, Tim K. T. Tse +4
This work proposes a Linear-Time-Invariance (LTI) notion to the Koopman analysis, finding an invariant subspace on which Koopman modes are consistent and physically meaningful. It…
Unbound Close Stellar Encounters in the Solar Neighborhood
Bradley M. S. Hansen
We present a catalog of unbound stellar pairs, within 100 pc of the Sun, that are undergoing close, hyperbolic, encounters. The data are drawn from the GAIA EDR3 catalogue, and the…
A Parametric and Feasibility Study for Data Sampling of the Dynamic Mode Decomposition: Spectral Insights and Further Explorations
Cruz Y. Li, Zengshun Chen, Tim K. T. Tse +4
This work continues the parametric investigation on the sampling nuances of the Dynamic Mode Decomposition (DMD) under the Koopman analysis. Through turbulent wakes, the investigat…
Strong enhancement of chlorophyll a concentration by a weak typhoon
Liang SUN, Yuan-Jian Yang, Tao Xian +2
Recent studies demonstrate that chlorophyll a (chl a) concentrations in the surface ocean can be significantly enhanced due to typhoons. The present study investigated chl a concen…
Different responses of the upper ocean to typhoon Namtheun
Yuan-Jian Yang, Liang Sun, Yun-Fei Fu
The responses of the upper ocean to typhoon Namtheun in July 2004 are investigated by sea surface measurements and vertical profiles. Pre-typhoon ocean environment played an import…
Impacts of Typhoons on the Kuroshio Large Meander: Observation Evidences
Liang Sun, Yuan-Jian Yang, Yun-Fei Fu
The formation of the Kuroshio large meander in summer 2004 was investigated by using the cruise data, Argo profiles data, and satellite remote sensing data. We validated the point…
