1. Evaluation of recycled MgO-C bricks and dead-burned dolomite fines in setting slag foaming in the electric arc furnace
Abstract Production cost reduction for the Electric Arc Furnace (EAF) technology is strongly dependent on the efficiency of the electrical energy being introduced into the metal bath. Besides EAF technology, the slag foaming process is currently applied to some other equipment for steel production aiming to save energy, productivity improvements, enhance the

2. Propostas de procedimentos para o estabelecimento de metas de qualidade do serviço de distribuição de energia elétrica. / Proposals of procedures for setting targets for power distribution service quality.
This work presents a review of the methodology used in PRODIST 2010, and alternative proposals for setting targets and rates depending on quality of service (QoS). All analysis are supported in statistical interruption data studies of 6 electricity distribution companies (EDC) between 2007 and 2008 with different characteristics of DEC, FEC, number of users

3. The role of demand response in electricity market spot price formation. / A importância da reação da demanda na formação dos preços de curto prazo em mercados de energia elétrica.
Given an economic environmental, a fundamental condition for a market be suitable to competition is that must has a plenty of buyers and, in special, those who can react to price signals. The consumers reaction aims at to adjust their energy requirements to the prices according to their disposal to access a certain product or service. As the price increases,

4. O programa nacional de universalização do acesso e uso da energia elétrica Luz para Todos e seus resultados na Bahia.
Access to electricity is directly related to the level of economic and social development of a particular country or region. Therefore, to examine how and to what degree this technology available to its inhabitants, becomes a relevant tool to obtain answers about the behavior of some socio-economic indicators. In Brazil, access to electricity in rural areas

5. Residential Energy Pricing, Privatization of the Sector and Social Impact in the period 1995 to 2005 / Tarifação Energética Residencial, Privatização do Setor e Impacto Social no período de 1995 a 2005
The electricity pricing constrain consumer access to this essential service. The industry, especially in its eletrointensivos sectors, requires energy the low cost, people need this service the compatible prices with its familiar income. However, during the process of privatization of the sector in Brazil, great distortions between the values charged for the

8. Automação como recurso de planejamento de redes de distribuição de energia elétrica. / Automation as resource for distribution systems planning.
Concerning the components of an electrical distribution network and their susceptibility to functional failures or need for maintenance actions, planning and project criteria should be adopted to assure continuity of energy supply even though some components may be out of work. Traditionally the power systems, especially in power transmission and distributio

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

11. Um estudo simplificado da percepção pública dos benefícios e riscos de centrais termonucleares - sugestões para a comunicação de valor com o público / Public perception on the benefits and risks of nuclear power plants_a simplified study
Public acceptance of the nuclear based electricity generation depends on many variables that can be affected by circumstances and interests, which although seemingly not close to the issue, can strongly influence the final outcome. Explicit or consented positions assumed by opinion makers and some segments of society are subject to episodic waves of interact
