Advection modes by optimal mass transfer

A Iollo, D Lombardi - Physical Review E, 2014 - APS
Classical model reduction techniques approximate the solution of a physical model by a
limited number of global modes. These modes are usually determined by variants of …

transport plans between point sets. It is particularly well-suited for point sets that are in high …

Data‐driven optimal transport

G Trigila, EG Tabak - Communications on Pure and Applied …, 2016 - Wiley Online Library
The problem of optimal transport between two distributions ρ (x) and μ (y) is extended to
situations where the distributions are only known through a finite number of samples {xi} and …

Bioinspired swimming simulations

M Bergmann, A Iollo - Journal of Computational Physics, 2016 - Elsevier
We present a method to simulate the flow past bioinspired swimmers starting from pictures of
an actual fish. The overall approach requires i) a skeleton graph generation to get a level-set …

Multi-physics optimal transportation and image interpolation
