Tropical Geometric Variation of Tree Shapes
Discrete & Computational Geometry, 2022 AbstractWe study the behavior of phylogenetic tree shapes in the tropical geometric interpretation of tree space. Tree shapes are formally referred to as tree topologies; a tree topology can also be thought of as a tree combinatorial type, which is given by the tree’s branching configuration and leaf labeling.

FEM Analysis of the Welding Seams Geometry in Case of Fillet Welds [PDF]
MATEC Web of Conferences, 2021 The role of the welding seam is to achieve the non-removable joint between two or more parts. In principle, three geometric profiles of the welding seams can be obtained: straight profile; concave profile and convex profile.

Observation of a non-adiabatic geometric phase for elastic waves [PDF]
, 2012 We report the experimental observation of a geometric phase for elastic waves in a waveguide with helical shape. The setup reproduces the experiment by Tomita and Chiao [A. Tomita, R.Y. Chiao, Phys. Rev. Lett.

Interpretation of geometric shapes [PDF]
Proceedings of the 2010 Symposium on Eye-Tracking Research & Applications - ETRA '10, 2010 This paper describes the first in a series of studies which seek to explore the correlation of eye movements with interpretation of geometric shapes. These studies are intended to inform the development of an eye tracking interface for computational tools to support and enhance the fluid interaction required in creative design.

Wulff construction in statistical mechanics and in combinatorics
, 2000 We present the geometric solutions to some variational problems of statistical mechanics and combinatorics. Together with the Wulff construction, which predicts the shape of the crystals, we discuss the construction which exhibits the shape of a typical ...

Repairing triangle meshes built from scanned point cloud [PDF]
, 2007 The Reverse Engineering process consists of a succession of operations that aim at creating a digital representation of a physical model. The reconstructed geometric model is often a triangle mesh built from a point cloud acquired with a scanner ...

Geometric morphometric analysis of spore shapes improves identification of fungi
PLoS ONE, 2021 Morphology of organisms is an essential source of evidence for taxonomic decisions and understanding of ecology and evolutionary history. The geometric structure (i.e., numeric description of shape) provides richer and mathematically different ...
