Tilings of a bounded region of the plane by maximal one-dimensional tiles
Eduardo J. Aguilar, Valmir C. Barbosa, Raul Donangelo +2
We study the tiling of a two-dimensional region of the plane by -cell one-dimensional tiles, or -mers. Unlike previous studies, which typically allowed for one single value o…
Configuration space partitioning in tilings of a bounded region of the plane
Eduardo J. Aguilar, Valmir C. Barbosa, Raul Donangelo +1
Given a finite collection of two-dimensional tile types, the field of study concerned with covering the plane with tiles of these types exclusively has a long history, having enjoy…
A simple linear model to aid in analyses of the Beta Pictoris moving group
Josina O. do Nascimento, Valmir C. Barbosa
We build a four-dimensional linear model of object membership in the Beta Pictoris moving group (BPMG), using two nested applications of Principal Component Analysis (PCA) to high-…
Experimental analysis of lateral impact on planar brittle material: spatial properties of the cracks
F. P. M. Santos, V. C. Barbosa, R. Donanelo +1
The breakup of glass and alumina plates due to planar impacts on one of their lateral sides is studied. Particular attention is given to investigating the spatial location of the c…
Experimental analysis of lateral impact on planar brittle material
F. P. M. dos Santos, V. C. Barbosa, R. Donangelo +1
The fragmentation of alumina and glass plates due to lateral impact is studied. A few hundred plates have been fragmented at different impact velocities and the produced fragments…
