13. Renderizações não fotorealísticas para estilização de imagens e vídeos usando areia colorida
Renderização Não Fotorealística (NPR) é uma classe de técnicas que almejam reproduzir técnicas artísticas, tentado expressar sentimentos e emoções nas cenas renderizadas, dando um aspecto de que foram feitas "manualmente". Outra forma de definir a NPR é como o processamento de cenas, imagens ou vídeos para geração de trabalhos de arte, gerando

14. ESTUDO MICROANALÍTICO DA PRECIPITAÇÃO DE MICRO E NANOPARTÍCULAS MAGNÉTICAS EM LIGAS DILUÍDAS DE CU-CO / MICROANALYTICAL STUDY OF MAGNETIC MICRO AND NANOPARTICLES PRECIPITATED IN DILUTE CU-CO ALLOYS
The isothermal decomposition processes of dilute Cu-Co bulk alloys have been investigated by means of analytical transmission electron microscopy. The precipitation of ferromagnetic Co particles in non-magnetic Cu matrix after aging treatments was revealed by a variety of electron-microscopy techniques: TEM diffraction contrast, high resolution electron micr

15. AUTORIA DE ALUNOS-ESCRITORES DE LÍNGUA ESTRANGEIRA: POSSIBILIDADE OU UTOPIA
Research on authorship has recently developed an understanding of the relationship between the writer and the meanings produced in mother tongue and in foreign language (ORLANDI, 2004; CARMAGNANI, 2001). Such a comprehension seems possible because authorship refers to the unity, originality, coherency, progression, non-textual contradiction (ORLANDI, 2004) a

16. A identidade profissional do professor de Matemática frente ao trabalho docente no ensino fundamental em ciclos
The current existence of a school in conflict, that operates at the same time in coherency with the premises of a serial organization, and in coherency with the premises of a cyclic organization, directed the interest of this research, that is to investigate how the Mathematics teachers understand and incorporate their work in classrooms organized in cycles,

17. Gobernanza en salud: un aporte conceptual y analítico para la investigación
In the Latin American region there is a notable absence of conceptual coherency in the use of the terms governability and governance. This is true for their application to both the social and political sciences and health. Researchers' understanding of governance varies, and the concept is used heterogeneously within academic circles, with ignorance of the t

18. Justificação econômico-financeira de AMT: um modelo de racionalidade, utilizando a visão baseada em recursos
The dissertation addresses the topic Economic-Financial Justification of AMT, i.e., the consideration of investments to be made in technology versus the benefits associated with their installation/implementation. The research proposes a model of rationale in order to deal with the problematic from the literature review. Such rationale is expressed through a

19. Gestão estratégica de energia elétrica e seus reflexos no desenvolvimento regional
Economic growth and increase of electric energy consumption are unquestioned historical facts and even nowadays, in developing countries, with a very strong correlation. However, the huge appropriation of energy resources and the residues emission in the nature caused by the industrial society had shown incompatible with a necessary environment sustainabilit

20. Computational model for the study unsteady open-channel flows / Modelo computacional para análise de transiente hidráulico em canais
This work presents a computational model developed in FORTRAN language for the study of unsteady open-channel flows with the use of Saint-Venant one-dimensional equation. The discretization of hydrodynamic equations are presented in a completely implicit method of finite differences and applied in the model for the investigation of two cases, besides the one

21. The extension of the LaSalle s Invariance Principle applied to generator coherency studies and multi-swing transient stability analysis. / O Princípio de Invariância de LaSalle estendido aplicado ao estudo de coerência de geradores e à análise de estabilidade transitória multi- swing .
As técnicas de análise de estabilidade transitória em sistemas elétricos de potência desenvolveram-se significativamente nas últimas duas décadas. Atualmente, o principal desafio dos pesquisadores é a obtenção de técnicas que sejam adequadasa análises em tempo real. Neste sentido, as idéias de Liapunov associadas ao Princípio de Invariância de

22. AGREGAÇÃO DINÂMICA DE MODELOS DE ESTABILIZADORES APLICADOS EM REGULADORES DE TENSÃO E CÁLCULO DE EQUIVALENTES DINÂMICOS / DYNAMIC AGGREGATION OF POWER SYSTEM STABILIZER MODELS APPLIED IN VOLTAGE REGULATORS AND CALCULATION OF DYNAMIC EQUIVALENTS
The calculation of coherency-based dynamic equivalents has three main steps: the identification of coherent generators, the network reduction and the dynamic aggregation of the coherent generating unit models. This dissertation deals with the problem of dynamic aggregation of power system stabilizer models to calculate coherency-based dynamic equivalents for

23. AGREGAÇÃO DINÂMICA DE MODELOS DE SISTEMAS DE EXCITAÇÃO E CÁLCULO DE EQUIVALENTES DINÂMICOS / DYNAMIC AGGREGATION OF EXCITATION SYSTEM MODELS AND CALCULATION OF DYNAMIC EQUIVALENTS
The methodology used to calculate dynamic equivalents has three basic steps: the identification of the coherent groups of generating units, the network reduction and the dynamic aggregation of coherent generator models. Among these steps, the last one has not been studied lately and deserves more development. This disseration deals with the problem of dynami

24. Política de recursos humanos na administração pública do Estado do Paraná: análise comparativa entre o discurso e a prática
The aim of this dissertation is to demonstrate what happens to the public administration in the state of Paraná through a case study, more specifically, in two organization: one, called in specific legal regime, 'direct administration' and the other, 'indirect administration', by means of structured interviews searching the distance between the discourse an
