Several aspects of three-dimensional Delaunay triangulation

, 1996
Due to the appearance of slivers, the quality of three-dimensional Delaunay triangulation may be inadequate for the application of the finite-element method (FEM).

Identifying and Mapping Industrial Districts Through a Spatially Constrained Cluster‐Wise Regression Approach

Journal of Regional Science, Volume 65, Issue 2, Page 403-428, March 2025.
ABSTRACT The aim of this article is to exploit an innovative spatial econometric approach to map and study the evolving patterns of industrial districts (IDs). The procedure can be classified as a k‐means cluster‐wise regression procedure and is designed to detect homogeneous areas of subcontracting activity.

Morpho‐structural analysis of impact craters on Pluto: Implications for the study of complex craters

Meteoritics &Planetary Science, EarlyView.
Abstract We used Pluto's global digital elevation model to automatically perform a morphometric analysis of impact craters. Triangular irregular networks (TINs) were generated for each crater, providing a detailed representation of crater topography and enabling more accurate morpho‐structural analysis. A dedicated toolkit generated radial profiles for

Triangulirajmo mnogokotnik [PDF]

Geodetski Vestnik, 2000
This paper considers different approaches how to divide polygons intotriangles what is known as a polygon triangulation. Polygons can be very complex in geodesic applications (they could have a lot of concave vertices, they could contain holes) therefore

On the Choice of Optimization Norm for Anderson Acceleration of the Picard Iteration for Navier–Stokes Equations

Numerical Methods for Partial Differential Equations, Volume 42, Issue 4, July 2026.
ABSTRACT While recent Anderson acceleration (AA) convergence theory [Pollock et al., IMA Num. An., 2021] requires that the AA optimization norm match the Hilbert space norm associated with the fixed point operator, in implementations the ℓ2$$ {\ell}^2 $$ norm is the most common choice. So far there is little research done regarding this discrepancy. To

Preprocessing imprecise points for Delaunay triangulation: Simplified and extended [PDF]

, 2010
Suppose we want to compute the Delaunay triangulation of a set P whose points are restricted to a collection R of input regions known in advance. Building on recent work by Löffler and Snoeyink, we show how to leverage our knowledge of R for faster ...
