Octahedron family: The double-expanded octahedron tensegrity

International Journal of Solids and Structures, 2019
Es un preprint The octahedron family of tensegrity structures is presented in this research. The octahedron and the expanded octahedron (well-known tensegrities in the literature) are the first and second components of the family. A new tensegrity is presented: the double-expanded octahedron.

Octahedral Tilt Instability of ReO_3-type Crystals [PDF]

, 2005
The octahedron tilt transitions of ABX_3 perovskite-structure materials lead to an anti-polar (or antiferroelectric) arrangement of dipoles, with the low temperature structure having six sublattices polarized along various crystallographic directions. It

Trees meet octahedron comparison

Journal of Topology and Analysis, 2023
We show that metric trees and their products meet the octahedron comparison, which is a certain six-point metric comparison similar to Alexandrov’s CAT(0) comparison.
