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 ...
Alocação de zeros aplicada a sistemas de controle via LMI
(2007-02-01)
A systematic procedure of zero placement to design control systems is proposed. A state feedback controller with vector gain K is used to perform the pole placement. An estimator with vector gain L is also designed for ...
Necessary conditions of optimality for vector-valued impulsive control problems
(2000-07-05)
A vector-valued impulsive control problem is considered whose dynamics, defined by a differential inclusion, are such that the vector fields associated with the singular term do not satisfy the so-called Frobenius condition. ...
Phase portraits of (2;0) reversible vector fields with symmetrical singularities
(2021-11-15)
In this paper we study the phase portraits in the Poincaré disk of the reversible vector fields of type (2;0) having generic bifurcations around a symmetric singular point p. We also prove the nonexistence of any periodic ...

Innovative dengue vector control interventions in Latin America: what dothey cost?
(Inglaterra, 2016)
Background Five studies were conducted in Fortaleza (Brazil), Girardot (Colombia), Machala (Ecuador), Acapulco (Mexico), and Salto (Uruguay) to assess dengue vector control interventions tailored to the context. The studies ...
Solucao de sistemas lineares com matrizes e vetores esparsos em computadores vetoriais
(1997-09-01)
This paper presents a methodology for solving a set of linear sparse equations on vector computers. The new methodology is able to exploit the matrix and vector sparsities. The implementation was made on a CRAY Y-MP 2E/232 ...
A single chart with supplementary runs rules for monitoring the mean vector and the covariance matrix of multivariate processes
(2013-08-15)
The MRMAX chart is a single chart based on the standardized sample means and sample ranges for monitoring the mean vector and the covariance matrix of multivariate processes. User's familiarity with the computation of these ...
Certifying the interruption of Chagas disease transmission by native vectors: cui bono?
(Fundaçao Oswaldo Cruz, 2013-03)
Certifying the absence of Chagas disease transmission by native vectors lacks scientific grounds and weakens long-term control-surveillance systems to the detriment of people living under risk conditions. Instead, a regular ...
Recent advances in phlebotomine sand fly research related to leishmaniasis control
(BioMed Central, 2015-01)
Phlebotomine sand flies are the subject of much research because of the role of their females as the only proven natural vectors of Leishmania species, the parasitic protozoans that are the causative agents of the neglected ...
