Visualization and selection of Dynamic Mode Decomposition components for unsteady flow

open access: yesVisual Informatics, 2021
Dynamic Mode Decomposition (DMD) is a data-driven and model-free decomposition technique. It is suitable for revealing spatio-temporal features of both numerically and experimentally acquired data.

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.

Constrained Dynamic Mode Decomposition

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2022
Frequency-based decomposition of time series data is used in many visualization applications. Most of these decomposition methods (such as Fourier transform or singular spectrum analysis) only provide interaction via pre- and post-processing, but no means to influence the core algorithm.

Application of dynamic mode decomposition and compatible window-wise dynamic mode decomposition in deciphering COVID-19 dynamics of India

open access: yesComputational and Mathematical Biophysics, 2023
The COVID-19 pandemic recently caused a huge impact on India, not only in terms of health but also in terms of economy. Understanding the spatio-temporal patterns of the disease spread is crucial for controlling the outbreak.

Generalized eigenvalue approach for dynamic mode decomposition

open access: yesAIP Advances, 2021
Traditional dynamic mode decomposition (DMD) methods inevitably involve matrix inversion, which often brings in numerical instability and spurious modes.

Bilinear dynamic mode decomposition for quantum control

open access: yesNew Journal of Physics, 2021
Data-driven methods for establishing quantum optimal control (QOC) using time-dependent control pulses tailored to specific quantum dynamical systems and desired control objectives are critical for many emerging quantum technologies.

Enhanced monopulse radar tracking using empirical mode decomposition [PDF]

open access: yes, 2010
Monopulse radar processors are used to track targets that appear in the look direction beamwidth. The target tracking information (range, azimuth angle, and elevation angle) are affected when manmade high power interference (jamming) is introduced to the

Randomized Projection Learning Method for Dynamic Mode Decomposition

open access: yesMathematics, 2021
A data-driven analysis method known as dynamic mode decomposition (DMD) approximates the linear Koopman operator on a projected space. In the spirit of Johnson–Lindenstrauss lemma, we will use a random projection to estimate the DMD modes in a reduced ...

Port-Hamiltonian Dynamic Mode Decomposition

open access: yesSIAM Journal on Scientific Computing, 2023
We present a novel physics-informed system identification method to construct a passive linear time-invariant system. In more detail, for a given quadratic energy functional, measurements of the input, state, and output of a system in the time domain, we find a realization that approximates the data well while guaranteeing that the energy functional ...
