Design of bi-metallic devices based on the topological derivative concept
(Pergamon-Elsevier Science Ltd., 2015-01)
In this work the topological derivative concept is applied in the context of topology design of thermo-mechanical devices, where the linear elasticity system (modeled by the Navier equation) is coupled with the steady-state ...
Topology design of thermomechanical actuators combined with heat source optimization
(Yokohama Publishers, 2019-11)
In the paper a problem of optimal topology and shape design of thermo-mechanical actuators with the heat source support is considered. The objective is to maximize the output displacement in a prescribed direction on the ...
Categoria de Lusternik-Schnirelmann e aplicações
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2022-02-14)
The Lusternik-Schnirelmann category associates a positive integer to each topological space. This number is an important invariant in algebraic topology, critical point theory and symplectic geometry. In this dissertation ...
On Topological Derivatives for Contact Problems in Elasticity
(Springer/plenum Publishers, 2014-06)
In this article, a general method for shape-topology sensitivity analysis of contact problems is proposed. The method uses domain decomposition combined with specific properties of minimizers for the energy functional. The ...
Topology design of thermomechanical actuators
(Springer, 2017-05)
The paper deals with topology design of thermomechanical actuators. The goal of shape optimization is to maximize the output displacement in a given direction on the boundary of the elastic body, which is submitted to a ...
Quantum walk topology and spontaneous parametric down conversion
(Springer, 2016-02)
Recently, it was proposed to study the complex physics of topological phases by an all optical implementation of a discrete-time quantum walk. The main novel ingredient proposed for this study is the use of non-linear ...
Network topology: patterns and mechanisms in plant-herbivore and host-parasitoid food webs
(Wiley, 2011-03)
Biological communities are organized in complex interaction networks such as food webs, which topology appears to be non-random. Gradients, compartments, nested subsets and even combinations of these structures have been ...
Looks Like Viscera. Folds, Wraps, and Relations in the Southern Andes
(Berghahn Books, 2019-07)
This article explores how viscera, bodies, and forces emerge in resemblance to one another. In the connections between the animals’ butcher, the treatment of body parts, and the rituals of herd marking in the Argentinean ...
Random braid gates for topological quantum circuits
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM FÍSICA, 2022-07-25)
Anyons are many-body states of electrons characterized by a permutation phase
between 0 and π. The non-abelian generalization of this concept was proposed
by Kitaev to make fault-tolerant quantum computers. For non-abelian ...
Computational material design for acoustic cloaking
(John Wiley & Sons Ltd, 2017-03)
A topology optimization technique based on the topological derivative and the level set function is utilized to design/synthesize the microstructure of a pentamode material for an acoustic cloaking device. The technique ...
