2. Sistema inteligente para alocação eficiente de dispositivos indicadores de falta em alimentadores de distribuição / An intelligent system for efficient allocation of fault indicators in distribution feeders
Fault Indicator (FIs) devices have contributed to improve the location of faults on primary feeders, and consequently the reliability of distribution systems. However, one of the main problems facing their installation in a large scale in a distribution system is the lack of efficient methods to analyze big networks and to pinpoint exactly on which buses the

3. Modeling the potential distribution of the invasive golden mussel Limnoperna fortunei in the Upper Paraguay River system using limnological variables.
The invasive golden mussel, Limnoperna fortunei (Dunker, 1857), was introduced into the La Plata River estuary and quickly expanded upstream to the North, into the Paraguay and Paraná rivers. An ecological niche modeling approach, based on limnological variables, was used to predict the expansion of the golden mussel in the Paraguay River and its tributarie

4. MODELOS DE CARGAS BASEADOS EM MEDIÇÕES PARA SIMULAÇÕES DINÂMICAS EM SISTEMAS ELÉTRICOS DE POTÊNCIA / MEASUREMENT-BASED LOAD MODELING FOR DYNAMIC SIMULATIONS ON ELECTRIC POWER SYSTEMS
This work describes a measurement-based load modeling methodology, using voltage and current data registered during power system disturbances. These load models are used on computational simulations for predicting power system stability after disturbances of system operational points. Practical results are presented of the proposed methodology, defining load

5. Real-time optimization of water supply system operation / Otimização energética em tempo real da operação de sistemas de abastecimento de água
This work presents a computational model for real-time optimization of water-distribution networks operation. An integrated software tool has been developed which is composed of three main modules: (i) a hydraulic simulator that performs the extended period simulation of the system (EPANET); (ii) a short-term demand-forecasting model, based on the moving Fou

6. ELECTRIC DISTRIBUTION POWER SYSTEMS RELIABILITY OPTIMIZATION: An Approach Considering the Selection and Allocation of Protection and Switching Devices / OTIMIZAÇÃO DA CONFIABILIDADE DE SISTEMAS DE DISTRIBUIÇÃO DE ENERGIA ELÉTRICA: Uma Abordagem Considerando a Seleção e Alocação de Dispositivos de Proteção e Manobras
One of the main goals of the electric utilities is to provide energy to its customers in a reliable and low cost way. Traditionally, the electricity sector regulatory commissions impose continuity targets, which must be carried out, to avoid great penalties. For many years, the electric utilities have adopted the practice of allowing the increment of tempora

7. Development of Real Time PCR to detect pol and env regions from HIV-1 subtypes B and F and screening of B/F recombinant strains. / Otimização de técnica de PCR em tempo real para detecção das regiões pol e env dos subtipos B e F de HIV-1 e triagem de seus recombinantes.
Background: The discovery of 42 HIV-1 circulating recombinant forms (CRF) together with the innumerous unique HIV recombinants forms, makes clear the role of genetic recombination for the epidemic. In Brazil, clades B, F, and C co-circulate, with 5 recently described CRFs. Real Time PCR is a rapid and reliable tool capable of detecting different HIV-1 subtyp

9. Técnica de gerenciamento da qualidade hídrica superficial baseada na otimização multiobjetivo / A technic of surface water quality management based on the multiobjective optimization
Problems of water quality management involve many aspirations of the users engaged, those that use water for wastewater dilution or for their consumption. Therefore, it is uncommon that decision-making mathematical models used are expressed in terms of a single objective, like the maximization of economic efficiency. Using a particular water system, one shou

11. ANALYSIS OF THE TRUSTWORTHINESS IN NETS OF DISTRIBUTION RADIAL: RECONFIGURATION AND ALOCATION OF DISTRIBUTED GENERATION / Análise da Cconfiabilidade em Redes de Distribuição Radiais: Reconfiguração e Alocação de Geração Distribuída
The distribution utilities must satisfy two concurrent objectives during planning process of the electric network: minimization of the investment cost and the satisfaction of reliability targets. An alternative to satisfy these objectives is to include low cost alternatives in the planning process. One of these alternatives is the reconfiguration of the dist
