Density and Packing in an Aggregate of Mixed Spheres
Journal of Applied Physics, 1949It is shown that in close packing of spheres, two types of interstice exist, bounded by six and by four convex spherical surfaces. These are termed ``square'' and ``triangular.'' They are connected by a continuous labyrinth through which a ball not exceeding (2/√3−1)r in radius can be threaded.

On the packing density of a fuzzy set
Cybernetics and Systems Analysis, 1994By a membership function of a fuzzy subset \(A\) of \(\mathbb{R}^n\) a function \(u_A : \mathbb{R}^n \to [0, \infty]\) is understood. If \(\sum^N_{j = 1} u_{K_j} (t) \leq u_G (t)\) then the density of \(G\) by \(K_1, \ldots, K_N\) is the number \(d = (\int_{R^n} u_G (t) dt)^{- 1}\) \((\sum^N_{j = 1} \int_{R^n} u_{K_j} (t)dt)\).

On packings and coverings of unit density
Mathematika, 1988When can a sequence \((C_ 1,C_ 2,...)\) of convex bodies in \(E^ n\) be rearranged by isometries so that the resulting sequence of congruent copies form a packing of density 1? In this paper it is proved that the conditions \[ \sum v(C_ i)=\infty \quad and\quad \lim_{i\to \infty}d(C_ i)=0 \] suffice.
