Packing the Hypercube

open access: yesDiscussiones Mathematicae Graph Theory, 2014
Let G be a graph that is a subgraph of some n-dimensional hypercube Qn. For sufficiently large n, Stout [20] proved that it is possible to pack vertex- disjoint copies of G in Qn so that any proportion r < 1 of the vertices of Qn are covered by the ...

Improving the Confining Properties against Oiling and Wetting of the Cardboard Paper Using PET Nanoparticles Coating

open access: yesIraqi Journal of Industrial Research, 2022
Paper or cardboard with porous surfaces have been transformed into oil- and water-resistant surfaces by coating them with nano-PET to fill the pores and increase their ability to absorb oil while keeping the fibers from swelling.

Packing Graphs: The Packing Problem Solved [PDF]

open access: yesThe Electronic Journal of Combinatorics, 1996
For every fixed graph $H$, we determine the $H$-packing number of $K_n$, for all $n > n_0(H)$. We prove that if $h$ is the number of edges of $H$, and $gcd(H)=d$ is the greatest common divisor of the degrees of $H$, then there exists $n_0=n_0(H)$, such that for all $n > n_0$, $$ P(H,K_n)=\lfloor {{dn}\over{2h}} \lfloor {{n-1}\over{d}} \rfloor ...

Densest-Packed Columnar Structures of Hard Spheres: An Investigation of the Structural Dependence of Electrical Conductivity

open access: yesFrontiers in Physics, 2021
Identical hard spheres in cylindrical confinement exhibit a rich variety of densest-packed columnar structures. Such structures, which generally vary with the corresponding cylinder-to-sphere diameter ratio D, serve as structural models for a variety of ...
