Dear all,
On Wednesday, November 9nd, at 14h00 in Aula Dal Passo at Roma Tor Vergata, RoMaDS (https://www.mat.uniroma2.it/~rds/about.php) will host Alessandra Cipriani (UCL, London) with the seminar
"Topological data analysis: vineyards for metallic structures"
Abstract: Modeling microstructures is a problem that interests material science as well as mathematics. The most basic model for steel microstructure is the Poisson-Voronoi diagram. It has mathematically attractive properties and has been used in the approximation of single-phase steel microstructures. We would like to present methods that can be used to assess whether a real microstructure can be approximated by such a model. In this talk, we construct tests that use data coming from serial sectioning (multiple 2D sections) of a 3D metallic structure. The proposed statistics exploit tools from topological data analysis such as persistence diagrams and (a modified version of) persistence vineyards.
! Due to the hybrid nature of the topic, we would be grateful if you could forward this message to any person interested in Topological Data Analysis in your laboratory !
