Linear and nonlinear dimensionality reduction from fluid mechanics to machine learning

MA Mendez - Measurement Science and Technology, 2023 - iopscience.iop.org
Dimensionality reduction is the essence of many data processing problems, including
filtering, data compression, reduced-order modeling and pattern analysis. While traditionally …

A meshless method to compute pressure fields from image velocimetry

P Sperotto, S Pieraccini… - Measurement Science and …, 2022 - iopscience.iop.org
We propose a meshless method to compute pressure fields from image velocimetry data,

A meshless and binless approach to compute statistics in 3D Ensemble PTV

M Ratz, MA Mendez - Experiments in Fluids, 2024 - Springer
We propose a method to obtain super-resolution of turbulent statistics for three-dimensional
ensemble particle tracking velocimetry (EPTV). The method is “meshless” because it does …

CHARACTERIZATION OF A CAPILLARY-DRIVEN FLOW IN MICROGRAVITY BY MEANS OF OPTICAL TECHNIQUE

D Fiorini, L Carbonnelle, A Simonini… - Multiphase Science …, 2023 - dl.begellhouse.com
The motion of a gas-liquid interface along a solid wall is influenced by the capillary forces
resulting from the interface's shape and its interaction with the solid, where it forms a …

Meshless track assimilation (MTA) of 3D PTV data

P Sperotto, B Watz, D Hess - Measurement Science and …, 2024 - iopscience.iop.org
We propose a data assimilation algorithm to improve the resolution of 3D particle tracking
velocimetry (PTV) data and, as a byproduct, it estimates the pressure field. The proposed …
