[Soft-matter] Soft Matter and Stat Phys Seminar on 19 Nov 2021

[Maciej Lisicki]

Dear Soft Matter Colleagues and Friends,

On Friday 19 November 2021 at 9:30 AM at the UW Faculty of Physics (Pasteura 5, Warsaw; room 1.40) we are hosting a seminar during which

Rishabh Sharma (IFT UW)

will give a talk

Study of geometrical measures of wormholes using 4D-tomography

Abstract
In this work, we have used 4D micro-tomography (XCT) to study the dissolution channels aka wormholes. 16-bit grayscale scans of dissolving samples are obtained at constant time-interval during the dissolution experiments. The grayscale scans are segmented to binary images by a novel volume-based segmentation technique to preserve the maximum features of the wormhole. Finally, image-processing techniques such as connected-component labelling, smoothing median filters and skeletonization are used to extract the wormholes and their geometrical properties. Several measures such as tip-propagation, wastefulness and branchedness have been proposed which show a high correlation of wormhole propagation speed with rock internal structure.

We warmly welcome everyone to attend the talk and the Soft Matter Coffee Break after the seminar, held in room 4.51 (4th floor).
