Smoothing of nonsmooth differential systems near regular-tangential singularities and boundary limit cycles
(2021-06-01)
Understanding how tangential singularities evolve under smoothing processes was one of the first problem concerning regularization of Filippov systems. In this paper, we are interested in C n -regularizations of Filippov ...
Center boundaries for planar piecewise-smooth differential equations with two zones
(2017-01-01)
This paper is concerned with 1-parameter families of periodic solutions of piecewise smooth planar vector fields, when they behave like a center of smooth vector fields. We are interested in finding a separation boundary ...
Limit cycles bifurcating from discontinuous centres
(Oxford Univ Press, 2017-08-01)
In this article, we study limit cycles in discontinuous piecewise linear vector fields in R-2 and R-3. More precisely, we address the problem of understanding the dynamics around a degenerated two-fold singularity in R-2 ...
Initializing a mesoscale boundary layer model with radiosonde observations
(Springer, 2017-08)
A mesoscale boundary-layer model is used to simulate low-level regional wind fields over the La Plata River of South America, a region characterized by a strong daily cycle of land–river surface-temperature contrast and ...

Topological classification of limit cycles of piecewise smooth dynamical systems and its associated Non-Standard Bifurcations
(Multidisciplinary Digital Publishing Institute (MDPI), 2014-04-01)
In this paper, we propose a novel strategy for the synthesis and the classification of nonsmooth limit cycles and its bifurcations (named Non-Standard Bifurcations or Discontinuity Induced Bifurcations or DIBs) in n-dimensional ...
Numerical simulation of the planetary boundary layer in Iperó, SP-BrazilSimulação numérica da camada limite planetária na região de Iperó, SP-Brasil
(2000-01-01)
One-dimensional second order numerical model coupled with surface budget energy prognostic equations is used to simulate the planetary boundary layer (PBL) in the region of Iperó-SP. Model results indicate that vertical ...
Órbitas periódicas em sistemas diferenciais suaves por partes
(Universidade Estadual Paulista (Unesp), 2016-08-26)
Este trabalho está relacionado ao estudo de bifurcações e órbitas periódicas de sistemas diferenciais suaves por partes planares em duas e três zonas. Em sistemas com duas zonas, estamos interessados em encontrar uma ...
