Poissonian and non Poissonian Voronoi Diagrams with application to the aggregation of molecules
, 2009 The distributions that regulate the spatial domains of the Poissonian Voronoi Diagrams are discussed adopting the sum of gamma variate of argument two. The distributions that arise from the product and quotient of two gamma variates of argument two are ...

Compact and Efficient Topological Mapping for Large-Scale Environment with Pruned Voronoi Diagram
Drones, 2022 Topological maps generated in complex and irregular unknown environments are meaningful for autonomous robots’ navigation. To obtain the skeleton of the environment without obstacle polygon extraction and clustering, we propose a method to obtain high ...

Filaments of galaxies and Voronoi diagrams
Open Astronomy, 2018 The intersections between a spherical shell and the faces of Voronoi polyhedrons are numerically evaluated. The nodes of these intersections are the points that share the same distances from three nuclei.

On the existence of a neutral region
, 2012 Consider a given space, e.g., the Euclidean plane, and its decomposition into Voronoi regions induced by given sites. It seems intuitively clear that each point in the space belongs to at least one of the regions, i.e., no neutral region can exist.

Community detection by graph Voronoi diagrams
New Journal of Physics, 2014 Accurate and efficient community detection in networks is a key challenge for complex network theory and its applications. The problem is analogous to cluster analysis in data mining, a field rich in metric space-based methods. Common to these methods is

The use of Voronoi Structural System as an artistic Approach to Drawing & Painting
Journal of Architecture, Art & Humanistic Science, 2017 The research focuses on the use of Mathematics and Geometry in drawing and painting. Voronoi is one of these diagrams of Geometry that focuses on studying Algorithms. Voronoi can be seen as one of the Computational inventions and applications in Geometry.

Automatic Registration Of SAR And Optical Image Based On Line And Graph Spectral Theory [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 In this paper, a novel registration method is proposed by integrating the graph spectral theory and line features. The principal steps of our algorithm are as follows.

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions
Advanced Functional Materials, EarlyView.Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Anisotropy in the Hubble constant as modeled by density gradients
, 2014 The all-sky maps of the observed variation of the Hubble constant can be reproduced from a theoretical point of view by introducing an intergalactic plasma with a variable number density of electrons.
