Applied Sciences, 2021 One of the most restrictive conditions in ground transportation at high speeds is aerodynamic drag. This is even more problematic when running inside a tunnel, where compressible phenomena such as wave propagation, shock waves, or flow blocking can ...

A construction of small regular bipartite graphs of girth 8 [PDF]
Discrete Mathematics & Theoretical Computer Science, 2009 Let q be a prime a power and k an integer such that 3 ≤ k ≤ q. In this paper we present a method using Latin squares to construct adjacency matrices of k-regular bipartite graphs of girth 8 on 2(kq2 -- q) vertices.

Spectral ordering and 2-switch transformations [PDF]
The American Journal of Combinatorics, 2022 We address the problem of ordering trees with the same degree sequence by their spectral radii. To achieve that, we consider 2-switch transformations which preserve the degree sequence and establish when the index decreases.

Electronic Journal of Graph Theory and Applications, 2015 We study a family of graphs related to the $n$-cube. The middle cube graph of parameter k is the subgraph of $Q_{2k-1}$ induced by the set of vertices whose binary representation has either $k-1$ or $k$ number of ones.
