14. 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

15. TECHNOLOGICAL FORECASTING AT MEDIUM AND LONG TERM ABOUT HYDROGEN GENERATION PROCESS, CONSIDERING PROBABILISTICS FUTURE SCENARIOS AND TAKING INTO ACCOUNT FUEL CELLS DEVELOPMENT / Previsão Tecnológica a médio e longo prazo sobre os processos de geração de Hidrogênio, considerando cenários futuros probabilísticos que levem em conta o desenvolvimento das pilhas a combustível
As Pilhas a Combustível estão cada vez mais atraindo o interesse como dispositivos de conversão de energia eficientes e, principalmente limpos. O Hidrogênio que alimenta as Pilhas a Combustível, deve ser gerado também de forma eficiente e limpa. Este trabalho utiliza a metodologia Delphi para Previsão Tecnológica aplicada ao assunto Geração de Hidr

16. Precipitation forecast aided by weather radar for early warning system of urban floods / Previsão de chuva com auxílio de radar de tempo visando a um sistema de alerta antecipado de cheias em áreas urbanas
To reduce human and material losses during floods it is feasible to concisely study the rainfall forecast as the main part of an early warning system. The use of weather radar information, when linked to physically-based forecast models, can contribute for monitoring and forecasting of intense rainfall episodes. Thus, the rainfall forecast, based on using of

17. Accounting earnings properties and determinants of earnings response coefficient in Brazil / Propriedades do lucro contábil e determinantes do coeficiente de resposta ao lucro no Brasil
A fundamental issue at the interface of economics, finance, and accounting involves the relation between a firms reported earnings and its stock returns. The lack of research in this field using Brazilian data and the limitations of previous research in terms of time-series data (small length available) motivates the present research. In addition, the practi

23. Modelagem computacional de estruturas anatômicas em 3D e simulação de suas imagens radiográficas / Computational 3D modelling of anatomic structures and simulation of its radiography images
The conventional methods of quality control applied to radio diagnosis are the best way to have assured good quality of the produced images. Due the amount of variables to consider, the study of particular issues of the process of formation of radiological images requires complementary computational tools. However, the computational voxel based phantoms are

24. Process of knowledge discovery in databases for analysis and warning of crop diseases and its application on coffee rust / Processo de descoberta de conhecimento em bases de dados para a analise e o alerta de doenças de culturas agricolas e sua aplicação na ferrugem do cafeeiro
Sistemas de alerta de doenças de plantas permitem racionalizar o uso de agrotóxicos, mas são pouco utilizados na prática. Complexidade dos modelos, dificuldade de obtenção dos dados necessários e custos para o agricultor estão entre as razões que inibem o seu uso. Entretanto, o desenvolvimento tecnológico recente - estações meteoro lógicas autom
