Merging enriched Finite Element triangle meshes for fast prototyping of alternate solutions in the context of industrial maintenance [PDF]

, 2010
A new approach to the merging of Finite Element (FE) triangle meshes is proposed. Not only it takes into account the geometric aspects, but it also considers the way the semantic information possibly associated to the groups of entities (nodes, faces ...

An atlas of K3 surfaces with finite automorphism group [PDF]

Épijournal de Géométrie Algébrique, 2022
We study the geometry of the K3 surfaces $X$ with a finite number automorphisms and Picard number $\geq 3$. We describe these surfaces classified by Nikulin and Vinberg as double covers of simpler surfaces or embedded in a projective space.

Discrete exterior geometry approach to structure-preserving discretization of distributed-parameter port-Hamiltonian systems [PDF]

, 2011
This paper addresses the issue of structure-preserving discretization of open distributed-parameter systems with Hamiltonian dynamics. Employing the formalism of discrete exterior calculus, we introduce a simplicial Dirac structure as a discrete analogue

On preferred point geometry in statistics [PDF]

, 2001
A brief synopsis of progress in differential geometry in statistics is followed by a note of some points of tension in the developing relationship between these disciplines. The preferred point nature of much of statistics is described and suggests the

ABOUT EFFICIENT MODELLING OF THE GEOMETRY FOR FINITE ELEMENT ANALYSIS

Journal of Industrial Design and Engineering Graphics, 2015
The current CAD platforms provides to user a wide variety of powerful geometric modelling tools, which allows the generation with a high accuracy the 3D geometry of the machinery components. If for achieving the fabrication documentation, the accuracy of

Thermal geometry from CFT at finite temperature

Physics Letters B, 2016
We present how the thermal geometry emerges from CFT at finite temperature by using the truncated entanglement renormalization network, the cMERA. For the case of 2d CFT, the reduced geometry is the BTZ black hole or the thermal AdS as expectation.

A characterization of finite \'etale morphisms in tensor triangular geometry [PDF]

Épijournal de Géométrie Algébrique, 2022
We provide a characterization of finite \'etale morphisms in tensor triangular geometry. They are precisely those functors which have a conservative right adjoint, satisfy Grothendieck--Neeman duality, and for which the relative dualizing object is ...

A New Approach to Identifying an Arbitrary Number of Inclusions, Their Geometry and Location in the Structure Using Topological Optimization

Applied Sciences, 2022
In the present paper, a new approach to identifying an arbitrary number of inclusions, their geometry and their location in 2D and 3D structures using topological optimization was proposed.

The Holographic Principle Comes from Finiteness of the Universe’s Geometry

Entropy
Discovered as an apparent pattern, a universal relation between geometry and information called the holographic principle has yet to be explained. This relation is unfolded in the present paper.

Image, geometry and finite element mesh datasets for analysis of relationship between abdominal aortic aneurysm symptoms and stress in walls of abdominal aortic aneurysm

Data in Brief, 2020
These datasets contain Computed Tomography (CT) images of 19 patients with Abdominal Aortic Aneurysm (AAA) together with 19 patient-specific geometry data and computational grids (finite element meshes) created from these images applied in the research ...
