Experimental Investigation of the Shock-Related Unsteadiness around a Spiked-Blunt Body Based on a Novel DMD Energy Sorting Criterion

Aerospace
In this study, we propose a novel dynamic mode decomposition (DMD) energy sorting criterion that works in conjunction with the conventional DMD amplitude-frequency sorting criterion on the high-dimensional schlieren dataset of the unsteady flow of a ...

A Forecasting Method Based on a Dynamical Approach and Time Series Data for Vehicle Service Parts Demand

Engineering Proceedings
In the automotive industry, the supply of service parts—such as bumpers, batteries, and aero parts—is required even after the end of vehicle production, as customers need them for maintenance and repairs.

Experimental Study of Shock Wave Boundary Layer Interaction Using High-Frame-Rate Schlieren Images

Aerospace
An experimental study was conducted on Mach 3 compression-ramp-induced shock wave/boundary layer interactions (20–30° ramp angles) using time-resolved schlieren imaging at 50 kHz.

High-Order Dynamic Mode Decomposition for Multidimensional Harmonic Retrieval

Estimating channel parameters such as azimuth, elevation, Doppler shift, and delay is a key challenge in wireless communication, often formulated as a multidimensional harmonic retrieval (MHR) problem.

Study of the vibration pattern synthesis in structures using Dynamic Mode Decomposition (DMD)

The present thesis addresses the use of Dynamic Mode Decomposition (DMD) for the analysis of vibration patterns in structures, particularly in a cantilever beam. Using a Finite Element Method (FEM) model, synthetic data of the beam response is generated for three different cases: harmonic response, free response and impact response.

Dynamic mode decomposition with control

, 2014
We develop a new method which extends Dynamic Mode Decomposition (DMD) to incorporate the effect of control to extract low-order models from high-dimensional, complex systems.
