Geometry-aware point cloud clustering for spherical-component aggregate modeling. [PDF]

open access: yesSci Rep
This paper proposes a method for obtaining independent mesh models of individual components from a point cloud representing an aggregate. An aggregate consists of a collection of small, similar components, such as individual grapes in a bunch.

Comparing the Dynamics of Free Subduction in Cartesian and Spherical Domains

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The effects of sphericity are regularly neglected in numerical and laboratory studies that examine the factors controlling subduction dynamics. Most existing studies have been executed in a Cartesian domain, with the small number of simulations ...

Random Motions at Finite Velocity on Non-Euclidean Spaces

open access: yesMathematics, 2022
In this paper, random motions at finite velocity on the Poincaré half-plane and on the unit-radius sphere are studied. The moving particle at each Poisson event chooses a uniformly distributed direction independent of the previous evolution. This implies

Innovative Tool to Determine Radiative Heat Transfer Inside Spherical Segments

open access: yesApplied Sciences, 2023
The classic equations used to find the form factor inside fragments of spheres are often unassailable. The main difficulties that they present lie in iterative integrations effected over curved surfaces.

Stokes Equation in a Semi-Infinite Region: Generalization of the Lamb Solution and Applications to Marangoni Flows

open access: yesFluids, 2020
We consider the creeping flow of a Newtonian fluid in a hemispherical region. In a domain with spherical or nearly spherical geometry, the solution of the Stokes equation can be expressed as a series of spherical harmonics.
