Closed poly-trajectories and Poincaré index of non-smooth vector fields on the plane
(2013-04-01)
This paper is concerned with closed orbits of non-smooth vector fields on the plane. For a class of non-smooth vector fields we provide necessary and sufficient conditions for the existence of closed poly-trajectorie. By ...

Poincaré plot indexes of heart rate variability: Relationships with other nonlinear variables
(2013-10-01)
The Poincaré plot for heart rate variability analysis is a technique considered geometrical and non-linear, that can be used to assess the dynamics of heart rate variability by a representation of the values of each pair ...

Dynamic systems behaviour analysis and design based on the qualitative theory of differential equations: The Boost power converter case
(TAYLOR AND FRANCIS LTD., 2015-06-03)
This paper uses the qualitative theory of differential equations to analyse/design the dynamic behaviour of control systems. In particular, the Poincaré compactification and the Poincaré - Hopf theorem are used for analysing ...
Functions and vector fields on C(ℂPn)-singular manifolds
(2015-12-01)
In this paper we study functions and vector fields with isolated singularities on a C(ℂPn)-singular manifold. In general, a C(ℂPn)-singular manifold is obtained from a smooth (2n + 1)-manifold with boundary which is a ...
