1. A SIR Model with Spatially Distributed Multiple Populations Interactions for Disease Dissemination
ABSTRACT In this contribution we analyze a discretized SIR (Susceptible, Infectious, and Removed) compartmental model, to investigate the role of individual interactions in the spread of diseases. The compartments S i,j , I i , j and R i , j ( i , j , = 1 , 2 , . . . , n ) are spatially distributed in a two-dimensional n × n network. We assume tha

3. Breaking the misconception of a dry and lifeless semiarid region: the diversity and distribution of aquatic flora in wetlands of the Brazilian Northeast
ABSTRACT The semiarid region of northeastern Brazil possesses a set of wetlands characterized by hydrographic basins with deficient drainage networks, a few large and permanent lotic systems and several permanent and temporary lagoons. Aquatic plants are widely distributed in these wetlands and the present study aims to determine if those of Ceará state hav

4. ALTERNATIVES TO ESTIMATE THE VOLUME OF INDIVIDUAL TREES IN FOREST FORMATIONS IN THE STATE OF MINAS GERAIS, BRAZIL
ABSTRACT The objective of this study was to compare different alternatives to estimate the stem volume of individual trees in four different forest formations in the Minas Gerais state, Brazil. The data were obtained in a forest inventory procedure performed by the Minas Gerais Technological Center Foundation. The stem volumes were computed by the Smalian ex

5. Computational algorithm for stability analysis of distribution networks with distributed generation
Abstract With the insertion of distributed generation in distribution networks, security analysis becomes crucial, in islanded operation or when the system is connected to the grid. Dynamic stability analyses are necessary in order to achieve minimum levels of security and reliability. Such analyses are obtained through the solution of the algebraic-differen

6. Optimal pressure management in water distribution networks through district metered area creation based on machine learning
RESUMO A gestão integrada dos sistemas de abastecimento de água com o uso eficiente dos recursos requer a otimização das operações. O agrupamento das redes de abastecimento de água em pequenas unidades, chamadas de distritos de medição (DMAs), é uma estratégia que permite o desenvolvimento de regras operacionais específicas, responsáveis por mel

7. Dynamics of the botanical knowledge of the Laklãnõ-Xokleng indigenous people in Southern Brazil
ABSTRACT We analyzed the botanical knowledge of the Laklãnõ-Xokleng people in the Ibirama Laklãnõ Indigenous Territory. They are the last remnant of this ethnicity living in a unitary socio-political organization. The objective was to investigate the dynamics, distribution and transmission of botanical information. We interviewed 112 people in two villag

10. The use of Social Network Analysis in a study of intergroup relations between affirmative action and regular students in a public university
Resumo A adesão ao sistema de cotas no ensino superior promoveu a convivência entre grupos sociais distintos. O estudo avaliou o padrão de interação entre 926 estudantes cotistas e não cotistas de 25 turmas de uma universidade pública brasileira, utilizando um questionário de redes sociais informais. Homofilia foi o parâmetro escolhido para medir as

11. Power Flow Analysis and Self-recovery of Electrical Energy Distribution Network Using Artificial Neural Networks
ABSTRACT A computational model for self-recovery of electricity distribution network was developed to simulate it, emulated by the IEEE 123 node model. The electrical system considered has automatic switches capable of identifying a momentary failure in the line and finding the best reconfiguration for its reclosing. An artificial neural network (ANN), backp

12. Technical Losses Reduction in Underground Reticulated Distribution Systems using Artificial Neural Networks and Smart Grid Features
ABSTRACT This work presents the methodology, development and testing of an autonomous system, based on Artificial Neural Networks (ANN), for the reduction of technical losses in reticulated underground systems through the optimal control of the capacitor banks (CBs) present in the grid. The proposed methodology includes Smart Grid features, including practic
