Topological equivalence of nonautonomous difference equations with a family of dichotomies on the half line
(Amer Inst Mathematical Sciences-AIMS, 2021)
A linear system of di erence equations and a nonlinear perturbation
are considered, we obtain su cient conditions to ensure the topological
equivalence between them, namely, the linear part satis es a property of ...
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 ...
Singular levels and topological invariants of Morse–Bott foliations on non-orientable surfaces
(2018-03-01)
We investigate the classification of closed curves and eight curves of saddle points defined on non-orientable closed surfaces, up to an ambient homeomorphism. The classification obtained here is applied to Morse–Bott ...
Classificação de imagens tridimensionais por meio de homologia persistente e imagem de persistência.
(Universidade Estadual Paulista (Unesp), 2022-09-08)
O trabalho desenvolvido traz um estudo sobre o agrupamento de imagens tridimensionais por meio da Análise Topológica de Dados (TDA). Nos primeiros capítulos, as principais definições da Topologia Algébrica são apresentadas ...

Differential mixer with NMOS/PMOS stack at switching stage
(2012-12-14)
This paper proposes a novel differential mixer topology. The traditional stage of switching is replaced by a stack of NMOS and PMOS transistors combined. A design is given of a 900 MHz down-conversion mixer using a 0.35 ...

Topology design of plates considering different volume control methods
(Emerald Group Publishing Limited, 2014-06)
Purpose – The purpose of this paper is to compare between two methods of volume control in the context of topological derivative-based structural optimization of Kirchhoff plates. Design/methodology/approach – The compliance ...
