Steklov Spectral Geometry for Extrinsic Shape Analysis

open access: yes, 2018
We propose using the Dirichlet-to-Neumann operator as an extrinsic alternative to the Laplacian for spectral geometry processing and shape analysis.

VPL geometry processing for open multilevel and multiscalar databases [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
This study investigates open-source VPL algorithms for storage, geolocalization and comparison of diagnostic multi-sensor data on 3D semi-automatic geometric database extracted from low-cost image-based models and shared on open web-based platform to ...

FACNet: Feature alignment fast point cloud completion network

open access: yesComputational Visual Media
Point cloud completion aims to infer complete point clouds based on partial 3D point cloud inputs. Various previous methods apply coarse-to-fine strategy networks for generating complete point clouds.

Modular discretization of the AdS2/CFT1 Holography [PDF]

open access: yes, 2013
We propose a finite discretization for the black hole geometry and dynamics. We realize our proposal, in the case of extremal black holes, for which the radial and temporal near horizon geometry is known to be AdS$_2=SL(2,\mathbb{R})/SO(1,1,\mathbb{R})$.

Gaussian process regression for geometry optimization [PDF]

open access: yesThe Journal of Chemical Physics, 2018
We implemented a geometry optimizer based on Gaussian process regression (GPR) to find minimum structures on potential energy surfaces. We tested both a two times differentiable form of the Matérn kernel and the squared exponential kernel. The Matérn kernel performs much better. We give a detailed description of the optimization procedures.

ANALYSIS OF THE VARIATION OF VIBRATIONS THAT APPEAR DURING TURNING WORKS WITH TRANSVERSE FEED DUE TO THE MODIFICATION OF THE FUNCTIONAL GEOMETRY OF THE CUTTING TOOL [PDF]

open access: yesFiabilitate şi Durabilitate, 2023
The paper aims to analyze the way in which the variation of the vibrations that appear during the machining processes by chipping during the transverse turning operation evolves due to the variation of the functional geometry of the chipping tool.

Writing Reusable Digital Geometry Algorithms in a Generic Image Processing Framework

open access: yes, 2012
Digital Geometry software should reflect the generality of the underlying mathe- matics: mapping the latter to the former requires genericity. By designing generic solutions, one can effectively reuse digital geometry data structures and algorithms.

Growth of shocked gaseous interfaces in a conical geometry [PDF]

open access: yes, 2003
The results of experiments on Richtmyer-Meshkov instability growth of multimode initial perturbations on an air-sulfur hexafluoride (SF6) interface in a conical geometry are presented. The experiments are done in a relatively larger shock tube.

Stochastic Geometry to Generalize the Mondrian Process

open access: yesSIAM Journal on Mathematics of Data Science, 2022
The stable under iterated tessellation (STIT) process is a stochastic process that produces a recursive partition of space with cut directions drawn independently from a distribution over the sphere. The case of random axis-aligned cuts is known as the Mondrian process.
