1. DISCOVERING AND LABELLING OF TEMPORAL GRANULARITY PATTERNS IN ELECTRIC POWER DEMAND WITH A BRAZILIAN CASE STUDY
ABSTRACT Clustering is commonly used to group data in order to represent the behaviour of a system as accurately as possible by obtaining patterns and profiles. In this paper, clustering is applied with partitioning-clustering techniques, specifically, Partitioning around Medoids (PAM) to analyse load curves from a city of South-eastern Brazil in São Paulo

2. Network modelling of palm biodiesel plants to supply the isolated electric power systems of Pará state
Despite the great advance brought by the National Interconnected System (NIS), which is able to provide clean hydroelectric power to almost all Brazilian customers, there are still cities supplied by power generated from fossil fuel, which are subsidized by taxes, they are called Isolated Electric Power Systems (IEPS). Pará State, that has 34 cities with IE

3. ESTUDO DE UM REATOR SOLAR HÍBRIDO PARA CURA ACELERADA DO CONCRETO EM ÁGUA MORNA. / STUDY OF A HYBRID SOLAR REACTOR FOR ACCELERATED CURING OF CONCRETE IN WARM WATER.
The Portland cement concrete material is the most consumed after the water worldwide due to their versatility molding, strength and durability as a structural material. The curing is the procedure that aims to keep the concrete saturated with water in their early ages and it is essential to ensure the reactions of cement hydration, promoting its consolidatio

4. Energy policy and regional inequalities in the Brazilian economy / Política energética e desigualdades regionais na economia brasileira
The objective of this dissertation is to evaluate the long-run regional impacts of tariff policy of the Brazilian electric power sector. The structural reforms carried on this sector determined the emergence of two different spatial distribution trends of the electric power tariffs among the Brazilian states: one of convergence and another of spatial diverge

5. Avaliação de processo de revisão tarifaria pedriodica das concessionarias de distribuição de energia eletrica no Brasil / Evaluation of the periodic tariff revision process for the brazilian electric power distribution utilities
The thesis originates in the evaluations of the economical regulation of the electric power sector in Brazil, particularly in what concerns the periodic tariff revision process implemented by the ANEEL, through the "tariff repositioning" methodology. This methodology ended up producing tariff injustices, with tariffs increases for the consumers of the econom

6. Programa de universalização de energia elétrica: estudo de caso no Estado da Bahia / Universalization program of electric energy: case study of the state of Bahia
This study is related to the development of the electricity services universalization process in Brazil. It describes the former model, the first universalization proposals, a legislation evolution since the beginning in 2002, its adaptation to the current situation among the country to the electric-power distribution companies, to costumers and to the conce

7. AnÃlise da evoluÃÃo da eficiÃncia das empresas distribuidoras de energia elÃtrica no Brasil, apÃs a reestruturaÃÃo do setor, no perÃodo de 2001 a 2005
The Electric Power Brazilian sector has been passing through big modifications, from the transferences of ownership to changes in market rules, mainly the supply activity. This market consists of 64 companies, under private and public control, with different sizes and for all national area. The study of the efficiency of the sector is important, as long as i

8. Analysis of participation of energy self producers and independent producers in the Brazilian electric sector. / Análise da participação dos autoprodutores e produtores independentes de energia no setor elétrico brasileiro.
Historically, the electric power supply in Brazil has a role that stands out in the domestic economic growth, due to its capacity to add revenue through the promotion to large-sized industries. Its strong association in the composition of the domestic revenue is of general concern of all individuals involved and interested in the power supply in Brazil, whic

9. Caracterização físico-química de materiais baseados em celulose
Switching cutout devices are electrical circuit breakers which protect electric power distribution webs against lightning discharges. Switching cutout devices main parts are the fuse links in which a fuse element, a special metallic alloy, melts due to the generated heat when struck by electric discharges. When such melting occurs, and the breaker opens, an

10. UMA ABORDAGEM BAYESIANA PARA O CÁLCULO DOS CUSTOS OPERACIONAIS EFICIENTES DAS DISTRIBUIDORAS DE ENERGIA ELÉTRICA / A BAYESIAN APPROACH TO ESTIMATE THE EFFICIENT OPERATIONAL COSTS OF ELECTRICAL ENERGY UTILITIES
This thesis presents the main results of the cost efficiency scores of 60 Brazilian electricity distribution utilities. Based on yardstick competition scheme, it was applied a Kohonen Neural Networks (KNN) to identify and to group the similar utilities. The KNN results are not deterministic, since the estimated weights are randomly initialized. Thus, a Monte

12. POSICIONAMENTO ESTRATÉGICO DAS DISTRIBUIDORAS DE ENERGIA ELÉTRICA NO BRASIL / STRATEGIC POSITIONING OF POWER DISTRIBUTION COMPANIES IN BRAZIL
The aim of this research is to understand the competitive dynamics on the Brazilian power sector, focusing on the distribution segment. We will try to understand how distribution companies have positioned themselves on their competitive environment, by the identification of their generic strategies and analyzing which of these strategies yielded a better per
