Optimal computation of brightness integrals parametrized on the unit sphere

open access: yes, 2012
We compare various approaches to find the most efficient method for the practical computation of the lightcurves (integrated brightnesses) of irregularly shaped bodies such as asteroids at arbitrary viewing and illumination geometries. For convex models,

A Viscous Boundary Layer Mesh Adaptation Method and Its Application in High-Angle-of-Attack Separated Flows

open access: yesApplied Sciences
Adjoint-based mesh adaptation method serves as an effective approach to improve the predictive accuracy of aerodynamic characteristics. However, viscous boundary layer grids often encounter issues such as hanging nodes, negative volumes, and directional ...

A Nystr\"om-based finite element method on polygonal elements

open access: yes, 2017
We consider families of finite elements on polygonal meshes, that are defined implicitly on each mesh cell as solutions of local Poisson problems with polynomial data.

A polyhedral approach for understanding flavonoid biosynthesis in Arabidopsis [PDF]

open access: yesNew Biotechnology, 2010
The sequencing of the entire genome of model plants has made it possible to use these plants for producing metabolites that are beneficial to humans. Plants produce a large number of metabolites, which are potentially valuable sources of novel pharmaceutically active agents that benefit human health.

Forman's Ricci curvature - From networks to hypernetworks

open access: yes, 2018
Networks and their higher order generalizations, such as hypernetworks or multiplex networks are ever more popular models in the applied sciences. However, methods developed for the study of their structural properties go little beyond the common name ...

Polyhedral meshing as an innovative approach to computational domain discretization of a cyclone in a fluidized bed CLC unit

open access: yesE3S Web of Conferences, 2017
Chemical Looping Combustion (CLC) is a technology that allows the separation of CO2, which is generated by the combustion of fossil fuels. The majority of process designs currently under investigation are systems of coupled fluidized beds.

The dynamical environment of asteroid 21 Lutetia according to different internal models

open access: yes, 2016
One of the most accurate models currently used to represent the gravity field of irregular bodies is the polyhedral approach. In this model, the mass of the body is assumed to be homogeneous, which may not be true for a real object.

A Polyhedral Approach for Scalar Promotion

open access: yes, 2022
Memory accesses are a well known bottleneck whose impact might be mitigated by using properly the memory hierarchy until registers. In this paper, we address array scalarization, a technique to turn temporary arrays into a collection of scalar variables to be allocated to registers.
