On Some Problem for a Simplex and a Cube in Rⁿ
Моделирование и анализ информационных систем, 2013 Let S be a nondegenerate simplex in Rⁿ. Denote by α(S) the minimal σ > 0 such that the unit cube Qn:= [0, 1]ⁿ is contained in a translate of σS. In the case α(S) ≠ 1 the translate of α(S)S containing Qn is a homothetic copy of S with the homothety ...

Effect of Nanoscale Confinement on the \beta-\alpha Phase Transition in Ag2Se [PDF]
, 2007 The confinement of silver selenide was investigated using mesoporous silica. Results from x-ray diffraction and electron microscopy show that the confined material still exhibits a \beta to \alpha transition similar to the one that takes place in the ...

The Hyper-Wiener Index of Trees of Order n with Diameter d
Discrete Dynamics in Nature and Society, 2016 The hyper-Wiener index is a kind of extension of the Wiener index, used for predicting physicochemical properties of organic compounds. The hyper-Wiener index WW(G) is defined as WW(G)=1/2∑u,v∈VGdGu,v+dG2u,v with the summation going over all pairs of ...

On the Steiner antipodal number of graphs
Electronic Journal of Graph Theory and Applications, 2019 The Steiner n-antipodal graph of a graph G on p vertices, denoted by SAn(G), has the same vertex set as G and any n(2 ≤ n ≤ p) vertices are mutually adjacent in SAn(G) if and only if they are n-antipodal in G.

On n-Dimensional Simplices Satisfying Inclusions S ⊂ [0, 1]n ⊂ nS
Моделирование и анализ информационных систем, 2017 Let \(n\in{\mathbb N}\), \(Q_n=[0,1]^n.\) For a nondegenerate simplex \(S\subset {\mathbb R}^n\), by \(\sigma S\) we denote the homothetic image of \(S\) with the center of homothety in the center of gravity of \(S\) and ratio of homothety ...
