Sphere packings in Euclidean space with forbidden distances

open access: yesForum of Mathematics, Sigma
In this paper, we study the sphere packing problem in Euclidean space where we impose additional constraints on the separations of the center points. We prove that any sphere packing in dimension $48$ , with spheres of radii r, such that no two ...

Packing dimension results for anisotropic Gaussian random fields

open access: yes, 2011
International audienceLet $X=\{X(t), t \in \R^N\}$ be a Gaussian random field with values in $\R^d$ defined by $$X(t) = \big(X_1(t), \ldots, X_d(t)\big), \qquad \forall \ t \in \R^N, $$ where $X_1, \ldots, X_d$ are independent copies of a centered real ...

An Effective Corner Increment-Based Algorithm for the Two-Dimensional Strip Packing Problem

open access: yesIEEE Access, 2018
The 2-D strip packing problem is an NP-hard combinatorial optimization problem. Given a strip with fixed width and infinite height, the aim of strip packing is to pack a set of rectangles with known widths and heights into the strip such that the used ...

Packing Multidimensional Spheres in an Optimized Hyperbolic Container

open access: yesMathematics
The problem of packing multidimensional spheres in a container defined by a hyperbolic surface is introduced. The objective is to minimize the height of the hyperbolic container under non-overlapping and containment conditions for the spheres ...

Use of genetic algorithms for solving problems of optimal cutting

open access: yesITM Web of Conferences, 2016
Cutting and packing problem is one of the most common optimization problem. Even a small space or material savings allow obtaining substantial advantages on an industrial scale. This paper proposes the genetic algorithm to solve this problem. It includes

Divergence points of self-similar measures and packing dimension

open access: yes, 2007
Let μ be a self-similar measure in Rd. A point x∈Rd for which the limit limr↘0logμB(x,r)logr does not exist is called a divergence point. Very recently there has been an enormous interest in investigating the fractal structure of various sets of ...

Algorithmic Symplectic Packing [PDF]

open access: yes, 2021
In this thesis we explore a symplectic packing problem where the targets and domains are $2n$-dimensional symplectic manifolds. We work in the context where the manifolds have first homology group equal to $\Z^n$ and we require the embeddings to induce ...

A φ-Contractivity and Associated Fractal Dimensions

open access: yesFractal and Fractional
In this paper, we extend the concept of dimension of sets to some general frameworks relative to a gauge function φ, where two simultaneous dimensions are introduced.
