The braid index of DNA double crossover polyhedral links.

open access: yesPLoS ONE, 2020
In this paper, the authors study the mathematical properties of a class of alternating links called polyhedral links which have been used to model DNA polyhedra.

A polyhedral approach to edge coloring [PDF]

open access: yesOperations Research Letters, 1991
The edge coloring problem is formulated as an integer linear program of covering edges by matchings. For the NP-hard case of 3-regular graphs a linear programming relaxation with additional constraints is considered using column generation. The theory and the algorithm use the fact that the chromatic index is equal to 3 or 4.

Polyhedral Approaches to Mixed Integer Linear Programming [PDF]

open access: yes, 2009
This survey presents tools from polyhedral theory that are used in integer programming. It applies them to the study of valid inequalities for mixed integer linear sets, such as Gomory's mixed integer cuts.

Box-constrained optimization for minimax supervised learning*** [PDF]

open access: yesESAIM: Proceedings and Surveys, 2021
In this paper, we present the optimization procedure for computing the discrete boxconstrained minimax classifier introduced in [1, 2]. Our approach processes discrete or beforehand discretized features.

Identifying and remeshing contact interfaces in a polyhedral assembly for digital mock-up applications [PDF]

open access: yes, 2006
Polyhedral models are widely used for applications such as manufacturing, digital simulation or visualization. They are discrete models; easy to store, to manipulate, allowing levels of resolution for visualization.

A Featureless Approach to 3D Polyhedral Building Modeling from Aerial Images

open access: yesSensors, 2010
This paper presents a model-based approach for reconstructing 3D polyhedral building models from aerial images. The proposed approach exploits some geometric and photometric properties resulting from the perspective projection of planar structures.

Using polyhedral models to automatically sketch idealized geometry for structural analysis [PDF]

open access: yes, 2001
Simplification of polyhedral models, which may incorporate large numbers of faces and nodes, is often required to reduce their amount of data, to allow their efficient manipulation, and to speed up computation.

Virtual Elements on polyhedra with a curved face

open access: yesBulletin of Mathematical Sciences, 2023
We revisit classical Virtual Element approximations on polygonal and polyhedral decompositions. We also recall the treatment proposed for dealing with decompositions into polygons with curved edges.

Influence of chromium addition and cooling rate on Kinetic and microstructural evolution in FexCr100-x Metallic Glasses [PDF]

open access: yesE3S Web of Conferences, 2023
In this study, we utilized molecular dynamics simulations with the embedded-atom approach to explore how different cooling rates and concentrations of chromium (Cr) affect the vitrification of metallic glasses (MGs) composed of a binary alloy FexCr100-x.
