Du trimorphe aux frontières quasi topologiques

open access: yesAteliers d'Anthropologie, 2012
Topology is used in linguistics for semantic, lexical and grammatical descriptions. However, classical topology, with its notion of the limit, is insufficient. Therefore, to describe numerous semantic oppositions (such as “again” / “not again”, “already”

Topological boundary modes in isostatic lattices [PDF]

open access: yesNature Physics, 2013
Frames, or lattices consisting of mass points connected by rigid bonds or central force springs, are important model constructs that have applications in such diverse fields as structural engineering, architecture, and materials science. The difference between the number of bonds and the number of degrees of freedom of these lattices determines the ...

Topological inference of manifolds with boundary

open access: yesComputational Geometry, 2020
Given a set of data points sampled from some underlying space, there are two important challenges in geometric and topological data analysis when dealing with sampled data: reconstruction -- how to assemble discrete samples into global structures, and inference -- how to extract geometric and topological information from data that are high-dimensional,

RESEARCH ON POST-PROCESSING METHOD OF CONTINUUM STRUCTURE TOPOLOGY OPTIMIZATION BASED ON VARIABLE DENSITY METHOD

open access: yesJixie qiangdu, 2022
The variable density method has become an effective method to solve the topology optimization problem of continuum structure due to its advantages such as few design variables and high efficiency.

An Algorithm to Translate Building Topology in Building Information Modeling into Object-Oriented Physical Modeling-Based Building Energy Modeling

open access: yesEnergies, 2016
This paper presents an algorithm to translate building topology in an object-oriented architectural building model (Building Information Modeling, BIM) into an object-oriented physical-based energy performance simulation by using an object-oriented ...

A Theoretical Investigation of Flow Topologies in Bubble- and Droplet-Affected Flows

open access: yesFluids, 2019
A local flow topology analysis was conducted for laminar particle-affected flows. Based on the invariants of the velocity gradient tensor, all possible flow structures can be categorized into two focal and two nodal topologies for incompressible flows ...

Topological Boundary Constraints in Artificial Colloidal Ice [PDF]

open access: yesPhysical Review Letters, 2021
The effect of boundaries and how these can be used to influence the bulk behaviour in geometrically frustrated systems are both long-standing puzzles, often relegated to secondary role. Here we use numerical simulations and "proof of concept" experiments to demonstrate that boundaries can be engineered to control the bulk behavior in a colloidal ...

Induced Topological Phases at the Boundary of 3D Topological Superconductors [PDF]

open access: yesPhysical Review Letters, 2015
We present tight-binding models of 3D topological superconductors in class DIII that support a variety of winding numbers. We show that gapless Majorana surface states emerge at their boundary in agreement with the bulk-boundary correspondence.

Topological boundaries of covariant representations

open access: yesMATHEMATICA SCANDINAVICA, 2023
We associate a boundary $\mathcal B_{\pi ,u}$ to each covariant representation $(\pi ,u,H)$ of a $C^*$-dynamical system $(G,A,\alpha )$ and study the action of $G$ on $\mathcal B_{\pi ,u}$ and its amenability properties. We relate rigidity properties of traces on the associated crossed product $C^*$-algebra to faithfulness of the action of the group on
