CARACTERIZAÇÃO DE UM NOVO COMPLEXO BIMETÁLICO DE Pd ( II ) CONTENDO

This article reports the synthesis and characterization of a new binuclear complex of palladium (II) containing the antibiotic oxytetracycline. The complex was characterized by the usual techniques of analysis. With respect to sites of coordination, the IR spectral data suggests the involvement the oxygen of the amide group and the oxygen of the neighbor hydroxyl group at ring A and to the carb...

Estabilidade Robusta De Sistemas Lineares Através De Desigualdades Matriciais Lineares

Sufficient conditions for the analysis of stability of linear systems with polytopic uncertainties are presented in this paper. The robust stability is guaranteed by the existence of a parameter dependent Lypaunov function obtained from the feasibility test of a set of linear matrix inequalities (LMIs) formulated at the vertices of the uncertainty polytope. Three conditions are presented, and t...

Estabilidade de Classificadores de Decisão em Árvore Binária para Dados Imagem em Alta Dimensão

This paper deals with the problem of classifying high-dimensional image data image data using a multiple stage classifier structured as a binary tree. The aim here consists in finding the optimal structure for the binary tree in the sense of achieving a stable accuracy. The advantage presented by a multiple stage classifier lies on the fact that only a sub-set of classes is considered at each s...

Uma Formulação Lmi Para a Análise De Estabilidade Com Funções De Lyapunov Do Tipo Lur’e-persidskii

In this paper we propose an unified construction of Lyapunov functions based on Lur’e type functions that allows us to go from Persidskii’s to pure quadratic functions. Such Lyapunov functions allows the establishment of the absolute stability of nonlinear systems with nonlinearities belonging to given sectors. The sectors can be finite or infinite. An stability criterion is formulated in terms...
