Electrocatalytic study of an electrode modified with Reactive Blue 4 dye covalently immobilized on amine-functionalized silica
(Journal of Solid State Electrochemistry, 2012-12-01) [Artigo]
In the present work, we investigated the immobilization and electrochemical behavior of Reactive Blue 4 dye on 3-aminopropyl-functionalized silica. The electrochemical behavior of the modified electrode and the electro-oxidation ...
Electrochemical characterization of the paste carbon modified electrode with KSr2Ni0.75Nb4.25O15-delta solid in catalytic oxidation of the dipyrone
(Sensors and Actuators B: Chemical, 2012-07-05) [Artigo]
The electrochemical behavior of a carbon paste electrode modified (CPEM) with nickel-doped potassium strontium niobate (KSr2Ni0.75Nb4.25O15-delta) of tetragonal tungsten bronze (TTB)-type structure was investigated as a ...
Development of an electrochemical sensor for determination of dissolved oxygen by nickel-salen polymeric film modified electrode
(Sensors and Actuators B: Chemical, 2012-12-01) [Artigo]
An amperometric oxygen sensor based on a polymeric nickel-salen (salen = N,N'-ethylene bis(salicylideneiminato)) film coated platinum electrode was developed. The sensor was constructed by electropolymerization of nickel-salen ...
Enzymeless Hydrogen Peroxide Sensor Based on Mn-containing Conducting Metallopolymer
(26th European Conference on Solid-state Transducers, Eurosensor 2012, 2012-01-01) [Trabalho apresentado em evento]
The [(Mn4O5)-O-IV(terpy)(4)(H2O)(2)](6+) complex, show great potential for electrode modification by electropolymerization using cyclic voltammetry. The voltammetric behavior both in and after electropolymerization process ...
The assessment of the quality of sugar using electronic tongue and machine learning algorithms
(Proceedings - 2012 11th International Conference on Machine Learning and Applications, ICMLA 2012, 2012-12-01) [Trabalho apresentado em evento]
The correct classification of sugar according to its physico-chemical characteristics directly influences the value of the product and its acceptance by the market. This study shows that using an electronic tongue system ...
A model to store coordination mappings
(Proceedings of the International Conference on Information Visualisation, 2012-10-31) [Trabalho apresentado em evento]
Exploratory tasks supported by visualization are usually improved by Coordinated and Multiple Views (CMV) of the data under study. Several coordination techniques have been proposed in the literature, resulting in a diversity ...
Electropolymerization mechanism in aqueous solution of the oxo-manganese complex biomimicking of the enzymatic center present on the photosystem II
(ECS Transactions, 2012-12-01) [Trabalho apresentado em evento]
The [Mn4 IVO5(terpy)4(H 2O)2]6+ complex, show great potential for electrode modification by electropolymerization using cyclic voltammetry. The electropolymerization mechanism was based on the electronic transfer between ...
A Bayesian Analysis of Spectral ARMA Model
(Mathematical Problems in Engineering, 2012-01-01) [Artigo]
Bezerra et al. (2008) proposed a new method, based on Yule-Walker equations, to estimate the ARMA spectral model. In this paper, a Bayesian approach is developed for this model by using the noninformative prior proposed ...

Bayesian estimation of generalized exponential distribution under noninformative priors
(Xi Brazilian Meeting on Bayesian Statistics (ebeb 2012), 2012-01-01) [Trabalho apresentado em evento]
The generalized exponential distribution, proposed by Gupta and Kundu (1999), is a good alternative to standard lifetime distributions as exponential, Weibull or gamma. Several authors have considered the problem of Bayesian ...
