Advanced Science, EarlyView.The WTP is a key component of static drainage PEMFCs, enabling cathode water removal and gas sealing through capillary forces. This work investigates the mechanisms governing WTP drainage and sealing performance and develops predictive approaches for WTP design optimization.

Generalized Voronoi Diagram Computation on GPU
, 2011 We study the problem of using the GPU to compute the generalized Voronoi diagram (GVD) for higher-order sites, such as line segments and curves. This problem has applications in many fields, including computer animation, pattern recognition and so on.

A Matching Algorithm Based on Voronoi Diagram for Multi-Scale Polygonal Residential Areas
IEEE Access, 2018 Matching spatial entities (e.g., polygonal residential areas) from sources of significantly different map scales is challenging. The reason is that the same entities in two map scales have significant variations in their positions, structure shapes and ...

On levels in arrangements and voronoi diagrams [PDF]
Discrete & Computational Geometry, 1991 The author introduces a powerful technique of so-called \(\theta\) series and probabilistic games which are suitable for the analysis of combinatorial and algorithmical complexity of randomized geometric algorithms. Fundamental results concerning the construction of levels in an arrangement of hyperplanes and higher-order Voronoi diagrams in any ...

Advanced Science, EarlyView.Through methanol‐regulated interfacial polymerization (IP), bulky trifluoromethyl (‐CF3) groups are successfully integrated into polyamide networks. Unlike conventional membranes that suffer from severe solvent‐induced swelling, the fluorinated network sterically resists structural expansion.

Computation of Compact Distributions of Discrete Elements
Algorithms, 2019 In our daily lives, many plane patterns can actually be regarded as a compact distribution of a number of elements with certain shapes, like the classic pattern mosaic.

On Clustering Induced Voronoi Diagrams
SIAM Journal on Computing, 2013 In this paper, we study a generalization of the classical Voronoi diagram, called the clustering induced Voronoi diagram (CIVD). Different from the traditional model, CIVD takes as its sites the power set $U$ of an input set $P$ of objects. For each subset $C$ of $P$, CIVD uses an influence function $F(C,q)$ to measure the total (or joint) influence of

Voronoi Diagrams of Moving Points [PDF]
International Journal of Computational Geometry & Applications, 1998 Consider a set of n points in d-dimensional Euclidean space, d ≥ 2, each of which is continuously moving along a given individual trajectory. As the points move, their Voronoi diagram changes continuously, but at certain critical instants in time, topological events occur that cause a change in the Voronoi diagram.

Omni-Directional Capture for Multi-Drone Based on 3D-Voronoi Tessellation
Drones, 2023 This paper addresses the multi-drone formation capture in three-dimensional (3D) environments. The omni-directional minimum volume (ODMV) 3D-Voronoi diagram algorithm is proposed for the first time to achieve the two goals of (1) forming and keeping a ...

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning
Advanced Intelligent Discovery, EarlyView.This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...
