13. SIMULTANEOUS ALLOCATION OF SERVICES ACTIVE POWER AND REACTIVE AND ACTIVE AND LOSSES REACTION OF TRANSMISSION BASED ON THEORY ELECTRICAL CIRCUIT / ALOCAÇÃO SIMULTÂNEA DE SERVIÇOS DE POTÊNCIA ATIVA E REATIVA E DE PERDAS ATIVA E REATIVA DE TRANSMISSÃO BASEADA NA TEORIA DE CIRCUITOS ELÉTRICOS
Os métodos de alocação de serviços de potência ativa e reativa e das perdas de transmissão ativa e reativa têm recebido cada vez mais atenção após a reestruturação do setor elétrico, que promoveu livre acesso a diversos agentes (geradores e cargas), e com a crescente demanda de energia pela economia global. O principal objetivo dos métodos de a

14. Árvores de Steiner: Teoria, Geração Numérica e Aplicações / Steiner trees: Theory, Numerical Generation and Applications
Given a set of points in the plane, which we call terminals, one proves that they are always connected by a minimal graph called Steiner tree. The terminals may represent main connection route points, circuit elements or network computer servers. That is, the problem is to optimize traffic among the terminals whenever this is represented by a tree of shortes

15. ALOCAÇÃO DAS CARGAS E DAS PERDAS COMPLEXAS VIA TEORIA DOS JOGOS E DE CIRCUITOS / ALLOCATION OF LOADS AND COMPLEX LOSSES THROUGH GAME AND CIRCUIT THEORY
Due to the introduction of competition in the energy industry, it has become very important to determine and quantify the responsibility of each agent in transmission system losses, as well as to determine the participation of each generator to the loads. In this thesis, through the use of game theory, Aumann- Shapley method, and circuit theory are proposed

16. Calculo dos parametros de linhas de transmissão trifasicas atraves das tensões e correntes em seus terminais / Calculation of parameters of thress-phase transmission lines through voltages and currents in their terminals
The objective of this work is to calculate the longitudinal and transversal transmission line parameters using phase currents and voltages. Developed equations are used, in the modal domain, considering current and voltages found between a line terminal and an open line terminal, and a short-circuit terminal. . Initially, the basic transmission line theory i

17. O Circuito da Cultura e a estruturação de um discurso: fazendo sentido do vinho do Vale do São Francisco
Considering the increasing importance of culture for businesses and that social practices are cultural, involving the production of senses, we approached it through cultural studies and the circuit of culture, to understand dominant senses in social practices carried out through production, circulation and reception of a cultural product. For such, we used a

18. EstatÃstica de contagem de carga e efeitos de interferÃncia em sistemas mesoscÃpicos
In this thesis we presented a detailed study about full counting statistics of transmitted charge and accumulated phase and the quantum interference corrections to the average conductance and the average shot-noise power in non-ideal ballistic chaotic cavities. In the theoretical analysis of this mesoscopic system, we obtained analytical expressions for the

19. A implantação da assinatura digital no Tribunal Regional Federal da Quarta Região : perspectiva infocomunicacional
Avalia as percepções sobre o uso da Assinatura Digital no Tribunal Regional Federal da Quarta Região por parte dos Desembargadores, tendo como base teórica a Teoria dos Sistemas. Descreve a evolução das assinaturas como forma de identidade do indivíduo, desde os selos-cilindros da Mesopotâmia até a Assinatura Digital, baseada na tecnologia de cripto

20. Malabarismos no manejo do risco e proteção de famílias com crianças e adolescentes no sistema de garantia de direitos
Based on the Psychosociology and the Systemic Theory, the current research pointed out the risk and the protection of adolescents who have committed infractions with the regard of families in the system of rights guarantee inspired in a circus metaphor. Due to it, the present study proposed to understand how the rights guarantee net is legally constructed in

21. Você gostaria de participar de uma experiência artística? (+ NBP) / Você gostaria de participar de uma experiência artística? (+ NBP)
On this Thesis, I elaborate an investigation about Would you like to participate in an artistic experience?, a project of mine under development since 1994. This project involves aspects of participatory practices, issues on sculpture and installation, and an approach towards the art circuit. The research is developed in two complementary parts: firstly, the

22. Inconvertible money, financial derivatives and fictitious capital: the modern logic of forms / Dinheiro inconversível, derivativos financeiros e capital fictício: a moderna lógica das formas
Departing from the logical introduction of the inconvertible money form this dissertation investigates the scientific adequateness of the monetary and financial Marxist theories to the new post-1971 reality. The first part, constituted by the first two chapters, discusses the two main heritages that Marx received - Hegel and the English monetary thought from

23. Automatic generation and evaluation of transistor networks in different logic styles / Geração automática e avaliação de redes de transistores em diferentes estilos lógicos
Currently, VLSI design has established a dominant role in the electronics industry. Automated tools have enabled designers to manipulate more transistors on a design project and shorten the design cycle. In particular, logic synthesis tools have contributed significantly to reduce the design cycle time. In full-custom designs, manual generation of transistor

24. Language and children s drawing : aspects of deaf children symbolic development and its therapeutic implications / Linguagem e desenho infantil : aspectos do desenvolvimento simbolico da criança surda e implicações terapeuticas
The interest for childrens drawing goes back to the last half of the Nineteenth Century and has been the object of several specialized studies because pictographic representation is considered a way for observing and understanding childrens development. The present work intends to approach drawing, as one of the ways of representing, naming and signifyin
