Untangling the world-wide mesh of undersea cables [PDF]

open access: yesProceedings of the 17th ACM Workshop on Hot Topics in Networks, 2018
The growth of global Internet traffic has driven an exponential expansion of the submarine cable network, both in terms of the sheer number of links and its total capacity. Today, a complex mesh of hundreds of cables, stretching over 1 million kilometers, connects nearly every corner of the earth and is instrumental in closing the remaining ...

An Iterative Mesh Untangling Algorithm Using Edge Flip [PDF]

open access: yesMathematical Problems in Engineering, 2017
Existing mesh untangling algorithms are unable to untangle highly tangled meshes. In this study, we address this problem by proposing an iterative mesh untangling algorithm using edge flip. Our goal is to produce meshes with no inverted elements and good element qualities when inverted elements with poor element qualities are produced during mesh ...

Scientometrics: Untangling the topics [PDF]

open access: yes, 2014
Measuring science is based on comparing articles to similar others. However, keyword-based groups of thematically similar articles are dominantly small. These small sizes keep the statistical errors of comparisons high.

Computational Evolutionary Embryogeny [PDF]

open access: yes, 2010
Evolutionary and developmental processes are used to evolve the configurations of 3-D structures in silico to achieve desired performances. Natural systems utilize the combination of both evolution and development processes to produce remarkable ...

A Robust Solution Procedure for Hyperelastic Solids with Large Boundary Deformation

open access: yes, 2011
Compressible Mooney-Rivlin theory has been used to model hyperelastic solids, such as rubber and porous polymers, and more recently for the modeling of soft tissues for biomedical tissues, undergoing large elastic deformations.

An augmented Lagrangian formulation to impose boundary conditions for distortion based mesh moving and curving [PDF]

open access: yes, 2017
We formulate a mesh morphing technique as mesh distortion minimization problem constrained to weakly satisfy the imposed displacement of the boundary nodes.

Untangling High-Order Meshes Based on Signed Angles

open access: yes, 2020
One challenge in the generation of high-order meshes is that mesh tangling can occur as a consequence of moving the new boundary nodes to the true curved boundary. In this paper, we propose a new optimization-based method that uses signed angles to untangle invalid second- and third-order triangular meshes.

Distortion and quality measures for validating and generating high-order tetrahedral meshes [PDF]

open access: yes, 2015
A procedure to quantify the distortion (quality) of a high-order mesh composed of curved tetrahedral elements is presented. The proposed technique has two main applications.

Geometric Rounding and Feature Separation in Meshes

open access: yes, 2018
Geometric rounding of a mesh is the task of approximating its vertex coordinates by floating point numbers while preserving mesh structure. Geometric rounding allows algorithms of computational geometry to interface with numerical algorithms.
