13. GRAPH THEORY IN OPERATIONS OF THE HYDROTHERMAL SYSTEMS / TEORIA DE GRAFOS NA OPERAÇÃO DE SISTEMAS HIDROTÉRMICOS
The search for more efficiency in the production of eletrical energy, has led several countries to re- structure their eletric sectors, traditionally under control of federal, or state governments like in England, in /spain, in New Zeland, in argentina, in Chile, in Peru (object of this work), and now in Brasil. In this new structure the profit of the privat

14. Otimização da expansão conjunta da geração e transmissão em sistemas hidrotermicos de potencia atraves do algoritmo de decomposição de benders e equacionamento das incertezas relativas as vazoes afluentes aos reservatorios, das usinas hidroeletricas, previsões do mercado e custo de instalação das novas usinas
A new approach is developed in this work for the joint generationltransmission expansion planning of hydrothermal electric power systems. The goal is to determine the generating capacity of the candidate plants, the commissioning dates of their generating units, their production scheduling, the new transmission lines and their voltage levels, as well as the

15. ANALYSIS OF DIFFERENT ALLOCATION METHODOLOGIES OF COSTS AND BENEFITS APPLIED TO THE OPERATION AND PLANNING OF HYDROELECTRIC SYSTEMS / ANÁLISE DE DIFERENTES ALTERNATIVAS DE ALOCAÇÃO DE CUSTOS E BENEFÍCIOS APLICADOS À OPERAÇÃO E AO PLANEJAMENTO DE SISTEMAS HIDRELÉTRICOS
This thesis analyzes alternative methodologies for allocating coasting costs and benefits among participants of na energy generation pool. The impact of these alternative allocations with respect to revenues and dimensioning of new equipaments is assessed. Case studies, considering a system with six plants of Furnas Centrais elétricas S/A company, are prese

16. Planejamento da expansão da geração de sistemas hidrotermicos de potencia, otimizando os usos multiplos da agua dos reservatorios
A substantial contribution to the development of generation expansion planninq for hydrothermal power systems is aimed at in this work. The possible multiple uses of the water from candidate hydro plant reservoirs are considered, employinq conversational techniques of multiobjective programminq. Initially, a modeling based on linear programming is presented

17. DNA-DNA Solution Hybridization Studies of the Bacterial Symbionts of Hydrothermal Vent Tube Worms (Riftia pachyptila and Tevnia jerichonana)
The giant tube worm, Riftia pachyptila (phylum Vestimentifera), is known only from four widely separated sulfide-rich deep-sea hydrothermal vent systems. This invertebrate is nourished by intracellular, chemoautotrophic bacterial symbionts which reside in a specialized trophosome tissue. The symbiont has not been cultured independently and is believed to be
