Exact Voronoi diagram for topographic spatial analysis
GIScience & Remote Sensing, 2023 The Voronoi diagram (VD) is a fundamental geo-computing structure that has crucial applications. Computing this structure on a topographic surface requires having every point clustered on the geodesic distances, and thus the same challenging task as the ...

Degree four plane spanners: Simpler and better
Journal of Computational Geometry, 2017 Let $\mathcal{P}$ be a set of $n$ points embedded in the plane, and let $\mathcal{C}$ be the complete Euclidean graph whose point-set is $\mathcal{P}$. Each edge in $\mathcal{C}$ between two points $p$, $q$ is realized as the line segment $[pq]$ and is ...

Delaunay Triangulations with Predictions
CoRRWe investigate algorithms with predictions in computational geometry, specifically focusing on the basic problem of computing 2D Delaunay triangulations. Given a set ▫$P$▫ of ▫$n$▫ points in the plane and a triangulation ▫$G$▫ that serves as a "prediction" of the Delaunay triangulation, we would like to use ▫$G$▫ to compute the correct Delaunay ...

Conforming Delaunay triangulations in 3D
Computational Geometry, 2002 The authors present an algorithm to construct a Delaunay triangulation for a generated piecewise linear complex in three-dimensional space. The implementation shows that a relatively small number of Steine points are generated by the algorithm.

Direct Observation of Vortex Liquid Droplets in the Iron Pnictide Superconductor CaKFe4As4 at 0.5Tc
Advanced Science, EarlyView.Vortex matter in the iron‐based superconductor CaKFe4As4${\rm CaKFe}_4{\rm As}_4$ is visualized at the nanoscale, revealing the unexpected emergence of vortex‐liquid droplets far below the critical temperature. These localized fluctuating regions coexist with a vortex solid, demonstrating that dissipation‐related dynamics arise well before macroscopic ...

On Voronoi Diagrams on the Information-Geometric Cauchy Manifolds
Entropy, 2020 We study the Voronoi diagrams of a finite set of Cauchy distributions and their dual complexes from the viewpoint of information geometry by considering the Fisher-Rao distance, the Kullback-Leibler divergence, the chi square divergence, and a flat ...
