1. Effects of the Photovoltaic Distributed Generation on Electricity Distribution System Voltage - Updated Review
ABSTRACT Concerns about the environment and a growing demand for electricity have led to the intensive search for renewable energy sources. Photovoltaic solar energy, in the form of distributed generation, has shown a very high growth rate to an extent that in some regions it will be adopted on a large scale, thus being responsible for the supply of a signif

2. Oceanografia e Química: unindo conhecimentos em prol dos oceanos e da sociedade
The marine environment is certainly one of the most complex systems to study, not only because of the challenges posed by the nature of the waters, but especially due to the interactions of physical, chemical and biological processes that control the cycles of the elements. Together with analytical chemists, oceanographers have been making a great effort in

3. Aplicação de sistemas multiagentes para gerenciamento de sistemas de distribuição tipo Smart Grids / Application of multiagent systems for management of distribution systems like Smart Grids
Smart grids are taken as the new generation of electric power systems, combining advances in computing, distributed systems and artificial intelligence to provide more features on real-time monitoring of demand and consumption of electricity, managing large-scale distributed generators, among others, from a distributed control system on the grid. This approa

4. 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

5. Estudo do aumento do desempenho de um sistema de tomografia de impedância elétrica através do método de otimização topológica. / Increasing electrial impedance tomography system performance through the topology optimization method.
Electrical Impedance Tomography images the interior of a body based on electrical quantities measured on the surface of it. Mathematically, the technique finds the electric admittivity distribution in a given body model which reproduces the boundary measurements of electric currents and potentials on electrodes attached to that body. Therefore, the admittivi

6. MONOENERGETIC AND POLYENERGETIC GAMMA RAY COMPUTER TOMOGRAPHY FOR MULTIPHASE SYSTEMS ANALYSIS / Análise de sistemas multifásicos utilizando tomografia computadorizada Gama monoenergética e polienergética
It is important to recognize that at the heart of chemical transformations in all process and energy industries is multiphase reator technology, as over 99% of reator systems require the presence of more than one phase for proper operation. Tomography is a powerful technique capable of determining the effect of operating and design parameters on the phase ho

7. Evolutionary algorithm computationally efficient for distribution system reconfiguration / Algoritmo evolutivo computacionalmente eficiente para reconfiguração de sistemas de distribuição
O restabelecimento de energia em sistemas de distribuição de energia elétrica radiais geralmente envolve a reconfiguração de redes para restaurar eletricidade à(s) área(s) fora de serviço. As principais técnicas para restabelecimento de energia em sistemas de distribuição de grande porte têm sido os algoritmos evolutivos (AEs). Após a falta ter

8. Algoritmo para obtenção de planos de restabelecimento para sistemas de distribuição de grande porte / Algorithm for elaboration of plans for service restoration to large-scale distribution systems
A elaboração de planos de restabelecimento de energia (PRE) de forma rápida, para re-energização de sistemas de distribuição radiais (SDR), faz-se necessária para lidar com situações que deixam regiões dos SDR sem energia. Tais situações podem ser causadas por faltas permanentes ou pela necessidade de isolar zonas dos SDR para serviços de manut

9. PHYSICAL SIMULATION OF WELLBORE MECHANICAL BEHAVIOR / SIMULAÇÃO FÍSICA DO COMPORTAMENTO MECÂNICO DE POÇOS DE PETRÓLEO
A major problem during hydrocarbon production from poorly consolidated sandstone in the influx of sand, or sand production. This problem is complex and can occur as a result of a large variety of reasons, like magnitude of the in situ stresses, formation strength, and wellbore-development operations. If the potential for sand production could be predicted, t

10. H-N2N : uma arquitetura hierárquica escalável para ambientes de realidade mista de grande porte
In this work, we propose a solution to solve the scalability problem found in collaborative, virtual and mixed reality environments of large scale, that use the hierarchical client-server model. Basically, we use a hierarchy of servers. When the capacity of a server is reached, a new server is created as a sun of the first one, and the system load is distrib

11. Analise de estruturas coerentes de larga escala em jatos de dispersão bifasicos / Large scale coherent structures analysis in two-phase jets
A study of large scale coherent structures by Interparticle Arrival Time (IAT) of a two phase jet flow is proposed. Measurements were carried out for different initial velocities with 50 µm particle mean diameter, and for two different particle mixtures with mean particle diameter of 50 µm and 90 µm, in different proportions, and analyzed in relation to d

12. Luxlogger - autonomous system of daylight measurement of low cost / Luxlogger - sistema autônomo de medição de iluminação natural de baixo custo
The environmental issue has now created major discussions on renewable energy, being one of the major sources is the sun. However, the exploitation of its energy light has not yet been done on a large scale in countries that have such availability, such as Brazil. One reason may be the lack of a better understanding of how to make scaling of natural light. T
