A novel construction approach for the pore structure model principally focuses on the controllable roundness of rock particles

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 207-219, March 2026.
Particle rounding effects comparison of different methods: (a), (b), and (c) are the rounding results using the B‐spline curve method with different R; (d), (e), and (f) are the results of vertex rounding substitution method with different rounding radii.

Improved Jitter Elimination and Topology Correction Method for the Split Line of Narrow and Long Patches

ISPRS International Journal of Geo-Information, 2018
Extracting the split line of narrow and long patches is important for the generalization of land-use thematic data. There are two commonly used methods for extracting the split lines: One is based on Delaunay triangulation and the other is based on ...

Phase‐Resolved Finite Element Modeling of Electronic Transport in Hierarchical MoSe2@CoSe/N‐Doped Carbon Nanocomposites for Energy Storage and Electrocatalysis

Engineering Reports, Volume 8, Issue 3, March 2026.
Phase‐resolved finite element modeling reveals that the N‐doped carbon matrix and CoSe phase dominate electronic conduction in hierarchical MoSe2@CoSe nanocomposites, enabling uniform current redistribution, suppression of nanoscale electrical bottlenecks, and enhanced performance in sodium‐ion batteries and hydrogen evolution electrocatalysis ...

Refined Stratified Random Field Sampling for Inhomogeneous Turbulence Reconstruction

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT We present a refined stratified sampling method for the numerical simulation of a recently introduced random field model for the reconstruction of inhomogeneous turbulence from characteristic flow quantities. The refinement concerns the generation of random wave vectors and allows for an improved accuracy of the simulated fluctuation field.

The Extinction of the Contact Process in a One‐Dimensional Random Environment With Long‐Range Interactions

Random Structures &Algorithms, Volume 68, Issue 2, March 2026.
ABSTRACT We study the contact process on the long‐range percolation cluster on ℤ$$ \mathbb{Z} $$ where each edge ⟨i,j⟩$$ \left\langle i,j\right\rangle $$ is open with probability |i−j|−s$$ {\left|i-j\right|}^{-s} $$ for s>2$$ s>2 $$. Using a renormalization procedure, we apply the Peierls‐type argument to prove that the contact process dies out if the ...

Melanoma Detection Using Delaunay Triangulation

2015 IEEE 27th International Conference on Tools with Artificial Intelligence (ICTAI), 2015
The detection of malignant lesions in dermoscopic images by using automatic diagnostic tools can help in reducing mortality from melanoma. In this paper, we describe a fully-automatic algorithm for skin lesion segmentation in dermoscopic images. The proposed approach is highly accurate when dealing with benign lesions, while the detection accuracy ...

Technology of 3d relief modelling based on Delaunay triangulation algorithms

E3S Web of Conferences, 2019
This paper represents the algorithm of superimposing underwater relief and land relief basing on heterogeneous initial data with the use of Delaunay triangulation. As a result of superimposition a qualitative 3D relief model has been created.

Upper and Lower Bounds for Competitive Online Routing on Delaunay Triangulations

, 2014
Consider a weighted graph G where vertices are points in the plane and edges are line segments. The weight of each edge is the Euclidean distance between its two endpoints.

Fault Roughness Controls Seismicity Front Migration During Fluid Injection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The increasing occurrence of injection‐induced earthquakes has raised public concern and highlighted the importance of understanding subsurface processes and mechanisms to assess induced seismic hazards and risks. We develop a simple physics‐based model to investigate how fault roughness controls the migration of seismicity during fluid ...
