1. Generation of Photovoltaic Solar Energy. Evaluation of the Demand Curve with the Insert of Grid-connected Photovoltaic Power System at CINDACTA II, Curitiba-PR, Brazil.
ABSTRACT Unlike some countries, Brazil has a predominantly hydraulic energy matrix, a clean and renewable source. But, in recent years, both the non-renewal of the normal volumes of water in the reservoirs and the lack of consciousness in the consumption of water and energy have placed the country in a critical state of energy supply leading to many intensiv

2. Lower energy and pulse stacking. A safer alternative for skin tightening using fractional CO2 laser
PURPOSE : To evaluate the effect of different energies and stacking in skin shrinkage. METHODS : Three decreasing settings of a fractional CO2 laser were applied to the abdomen of Twenty five Wistar rats divided into three groups. Group I (n=5) was histologically evaluated for microthermal zones dimensions. Groups II and III (n=10 each) were macroscopic ev

3. Comercialização de bioeletricidade no ambiente de contratação livre pelas usinas do setor sucroenergético da região de Ribeirão Preto: panorama e análise das ameaças e oportunidades / Comercialitation of bioelectricity in the free contracting environment by the sugar cane mills of the sugar-energy sector from the region of Ribeirão Preto: scenery and analysis of opportunities e threats
In recent years, the Brazilian electricity market has gone through provision crises, due to the greater increase in demand with regard to supplies. Resulting from the lack of infrastructural investments and the concentration of the energy matrix in hydroelectricity, this scenario can be minimized by the bioelectricity coproduced based on sugar cane pulp. How

4. Dark energy and cyclic universe from Arnowitt-Deser-Misner renormalizable group approach
We discuss the generic features of the accelerated universe from Arnowitt-Deser-Misner renormalizable group approach applied for gravity models with variable gravitational coupling constant and cosmological constant. The universe undergoes an endless sequence of cosmic eras which starts inflating after a Big Bang and end contracting to a Big Crunch dominated

5. Análise da estratégia de contratação de consumidores livres, tendo como balizamento a formação de preços no mercado cativo. / Analysis of contracting strategies of free consumers, considering the energy pricing in regulated contracting market.
The availability of electrical energy at competitive prices is of fundamental importance for the competitiveness of products in each industry field, considering the strong competition in internal and external markets. The industry production plays an important role in society everyday life, contributing decisively to the smooth running of the Brazilian econo

6. Distribution companies contracting strategies in energy auctions / Estratégias de contratações das empresas distribuidoras nos leilões de energia
As mudanças no modelo energético trouxeram uma série de novas regras para as empresas de energia, entre as quais se destacam as regras de comercialização de energia elétrica. Nesse novo ambiente as empresas de distribuição (DISTCOS) atendem suas demandas esperadas principalmente através de contratos de longo prazo nos leilões de energia. Este traba

8. Estrategia de contratação otima na comercialização de energia eletrica / Optimal purchase strategy in energy trading
This research work has been developed in order to propose a methodology to represent the trading activities of the distribution utilities and energy trading companies, and also to provide guidelines to these companies when facing market conditions aiming at achieve optimal trading strategies addressing cost and risk minimization. For this purpose, it is requ

9. ESTRATÉGIA DE CONTRATAÇÃO DAS DISTRIBUIDORAS EM LEILÕES DE ENERGIA SOB INCERTEZA NA DEMANDA / CONTRACTING STRATEGIES IN ENERGY AUCTIONS FOR DISTRIBUTION COMPANIES UNDER DEMAND UNCERTAINTY
The objective of this work is to analyze the new regulatory framework of the Brazilian electric sector. In this sense, it was developed a computational tool in order to elaborate strategies for the distribution companies (DISCOs) in the energy auctions instituted by the new regulation. The computational tool was used to simulate the contracts acquisition pro

10. Aplicação de algoritmos genéticos para previsão do comportamento das distribuidoras como apoio à estratégia de comercialização de energia de agentes geradores. / Applying genetic algorithms for predicting distribution companies behavior to support generation companies power selling strategy.
As regras definidas pelo Decreto 5.163/2004 trazem incentivos e penalidades aos Distribuidores no processo de apresentação de suas declarações de necessidades de compra de energia ao Ministério de Minas e Energia. Nesse sentido, é importante para os Geradores estabelecer uma metodologia robusta para prever o comportamento dos agentes de distribuição

11. Criação da matéria em cosmologias com velocidade da luz variável e eletrônico não-linear
In this work we obtain the cosmological solutions and investigate the thermodynamics of matter creation in two diferent contexts. In the first we propose a cosmological model with a time varying speed of light c. We consider two diferent time dependence of c for a at Friedmann-Robertson- Walker (FRW) universe. We write the energy conservation law arising fro

12. Investment analysis of a thermal power plant: a deterministic and probabilistic assessment / AnÃlise de investimento de uma usina termelÃtrica : uma abordagem determinÃstica e probabiÃstica
Concerning the main changes which took place in the Brazilian electrical sector, there was an increase of competitiveness, especially in the field of energy production, where the new policy of buying and selling electricity occurs by means of auctions. This thesis has as an objective to demonstrate through deterministic and probabilistic studies the better l
