Simple yet robust triangulation for polygons containing multiple holes for real-time 3D industrial applications

Programación Matemática y Software
In industrial applications such as CAD modeling, manufacture or automated systems, it is common to work with data models that are represented by polygonal shapes, or models that produce polygonal shapes out of complex geometry defined by lines and ...

Examples, Counterexamples, and Enumeration Results for Foldings and Unfoldings between Polygons and Polytopes [PDF]

, 2000
We investigate how to make the surface of a convex polyhedron (a polytope) by folding up a polygon and gluing its perimeter shut, and the reverse process of cutting open a polytope and unfolding it to a polygon.

Additive Manufacturing of Negative Thermal Expansion Metamaterials Using Steels

Advanced Materials Technologies, EarlyView.
Architected lattices with tunable negative thermal expansion are fabricated from common steels using laser powder bed fusion metal additive manufacturing. Optimized multimaterial interfaces and geometry‐driven design produce robust, defect‐minimized structures that remain dimensionally stable up to 300 °C, enabling scalable solutions for thermal ...

Impact of a typical scanner delay processing parameter on local microstructure in metallic laser-based powder bed fusion

Additive Manufacturing Letters
In laser-based powder bed fusion of metals (PBF-LB/M), variations in laser scanner movements, particularly lesser-studied parameters like scanner delays that control laser directional changes, can influence the microstructure in a part during fabrication

How low can you go? Changing the resolution of novel complex objects in visual working memory according to task demands

Frontiers in Psychology, 2014
In three experiments we manipulated the resolution of novel complex objects in visual working memory (WM) by changing task demands. Previous studies that investigated the trade-off between quantity and resolution in visual WM yielded mixed results for ...

Covering a Simple Polygon by Monotone Directions

Computational Geometry, 2008
AbstractIn this paper we study the problem of finding a set of k directions for a given simple polygon P, such that for each point p∈P there is at least one direction in which the line through p intersects the polygon only once. For k=1, this is the classical problem of finding directions in which the polygon is monotone, and all such directions can be

NLP Formulation for Polygon Optimization Problems

Mathematics, 2018
In this paper, we generalize the problems of finding simple polygons with minimum area, maximum perimeter, and maximum number of vertices, so that they contain a given set of points and their angles are bounded by α + π where α
