16. Energia, meio ambiente e economia: o Brasil no contexto mundial
The cycle of fossil fuels as an energy source for mankind is approaching its end. Finite resources, coupled with greenhouse gas, have led to an increased effort in the search for alternative renewable energy sources. Brazil has a leading position, due to a 46% participation of renewable sources in its primary energy supply, compared to the global average of

17. Aspects of Crambe (Crambe abyssinica) Metabolism Under Different Nitrogen Doses Aiming the Oil Production for Biodiesel. / Aspectos do Metabolismo de Plantas de Crambe (Crambe abyssinica) Submetidas a Diferentes Doses de Nitrogênio Visando a Produção de Óleo para Biodiesel.
The crisis and projections around the petroleum business, lead a growning necessity to the development of alternatives energy sources. In this context, biofuel are characterized as a major alternative energy source and, between the countries with great potencial for its production, Brasil plays a role due to its possibilities in agroenergy. This is explained

18. CENÁRIOS FUTUROS DE OFERTA E DEMANDA DE ENERGIA ELÉTRICA: SIMULAÇÕES DO POSSÍVEL RACIONAMENTO ATÉ 2011 / FUTURES SETTINGS OF SUPPLY AND DEMAND OF ELECTRIC ENERGY: SIMULATIONS OF POSSIBLE ENERGY-RATIONING UNTIL 2011
The Brazilian electric energy generation system is a hydrothermal system of great size, with predominance hydroelectric plants. Its peculiar size and characteristics is the only one in the world. Consequently, its coordination is very complex and, therefore, it´s necessary the correct planning and operation to prevent or reduce problems related to supplemen

19. Análise de escala em bilhares com fronteiras móveis
We study numerically the scaling properties of some dynamical systems. Near the transition from the integrable to the non-integrable regime of complete e simplified versions of Fermi-Ulam model, we investigate the region of low energy (chaotic sea). We evaluate average quantities as functions (a) of the iteration number n or the time t, (b) of the initial ve

22. MULTICRITERIA OPTIMISATION OF HYDROTHERMAL SYSTEMS OPERATION USING GENETIC ALGORITHMS / OTIMIZAÇÃO MULTICRITÉRIO DA OPERAÇÃO DE SISTEMAS HIDROTÉRMICOS UTILIZANDO ALGORITMOS GENÉTICOS
In Brazil, the planning of the energy operation of the National Interconnected Power System is currently done through a chain of mathematical models designed to optimise the planning according to criterion of minimisation of the expected value of the total operation`s cost. However, since the 2001-2002 energy supply crisis, there was an intensification in th

24. AnÃlise do grau de concentraÃÃo no mercado de transmissÃo de energia elÃtrica no Brasil
A escassez de chuvas enfrentada em 2001 e a conseqÃente crise energÃtica enfrentada pelo PaÃs fizeram com que o Governo adotasse medidas para a reduÃÃo do consumo de energia, tais como o racionamento, a fim de evitar novas crises no setor. A reestruturaÃÃo do setor elÃtrico brasileiro, iniciada na dÃcada de 90, dividiu as atividades do mercado de en
