13. Busca meta-heurÃstica para resoluÃÃo de CSP em teste de software
The meta-heuristic search algorithms have been researched in several domains, including in constraint satisfaction problem. Due to its good adaptability to be used in problems where the actual solution is unknown, they are applied in innumerous contexts. The evolutive algorithms are a search algorithm family that simulates the nature behavior. The constraint

14. AlocaÃÃo de recursos com justiÃa: uma aplicaÃÃo de jogos cooperativos em redes de computadores
This work presents a methology for applying cooperative game theory concepts for solving the bandwidth allocation problem within differentiated traffic profiles for Internet applications. The multi-service networks scenario is explored as an operational network example for fair bandwidth sharing mechanisms. This operational network uses mechanisms based on s

15. Método estruturado para aplicação das técnicas de aumento da capacidade de produção de recursos gargalo em células de manufatura / Structured method for the application of techniques to increase bottleneck resource production capacity in manufacturing cells
The purpose of this work is structuring a sequence of application of a series of production capacity increase techniques mentioned in literature on an equipment bottleneck. This sequence must be placed into practice to increase production capacity of manufacturing lines in lean manufacturing environments. The work was developed through the analysis of the te

16. Extração de preferências por meio de avaliações de comportamentos observados. / Preference elicitation using evaluation over observed behaviours.
Recently, computer systems have been delegated to accomplish a variety of tasks, when the computer system can be more reliable or when the task is not suitable or not recommended for a human being. The use of preference elicitation in computational systems helps to improve such delegation, enabling lay people to program easily a computer system with their ow

17. ESCOLHA DE PARCEIROS E RESTRIÇÃO DE ORÇAMENTO
Our study started with predictions of the evolutionary psychology, along with the theory of market value, to study how men and women choose their partners. According to this approach, the way we choose our reproductive partners is based on the different selective pressures our ancestors had to face during the evolutionary process of natural and sexual select

18. Oscilador de Dirac: ImplicaÃÃes da violaÃÃo da simetria de Lorentz e da massa dependente da posiÃÃo.
In this work we study the Dirac Oscillator (DO) in a threefold way. In the first way, we study DO with Lorentz symmetry violation. This violation is implemented through vectorial and an axial terms. We realize a non-relativistic limit and we obtain that the background vector field does not modify the energy spectrum. However, in the case of the background ax

19. Trajectory planning of jumping over obstacles for hopping robot
Trajectory planning strategy is proposed to jump over an obstacle integrated three various dynamics in one-legged multi-joint hopping robot. A concept of inertia matching ellipsoid and directional manipulability are extended to optimize take-off postures. Optimized results have been used to plan hopping trajectory. Aimed at the sensitivity of motion trajecto

20. Estudo do fenômeno da auto-intersecção em um anel anisotrópico / Study of the self-intersection anomaly in an anisotropic ring
This work concerns a numerical study of a homogeneous circular plate with a centered hole that is under a state of plane strain. The plate is fixed at its inner surface and is under uniform radial compression at its outer surface. The plate is linear, elastic, and anisotropic. An analytical solution for this problem, which satisfies the governing equations o

21. As vogais médias em posição pretônica nos nomes no dialeto de Belo Horizonte: estudo da variação à luz da Teoria da Otimalidade
The objective of this research is to analyze the variation of mid-height vowels in pre-stressed-syllable position in nouns spoken in the dialect of Belo Horizonte, taking into consideration linguistic factors and phonological processes, such as vowel harmony and vowel reduction, which interfere with this production. Variation is also studied using Optimality

22. Estimação da oferta de trabalho com modelos coletivos: uma aplicação para o Brasil / Estimation of labor supply with collective models: an application for Brazil
This paper has as objective to investigate the Brazilian spouseslabor supply behavior and to empirically check the adequacy of a specific collective model. The collective labor supply model with distribution factors offers a theoretical structure to interpret the intra-household decision process and its results, the familieschoices of consumption and labor s

23. Variação das vogais médias em posição pretônica nas regiões norte e sul de Minas Gerais :: uma abordagem à Luz da Teoria da Otimalidade
The current dissertation presents an analysis concerning the behaviour of the medium vowels, in pre-stress position, based on the data obtained from the dialects of the areas South and North of the State of Minas Gerais. In such areas, an interesting phenomenon is produced, which is basically summarized in the following aspects: in the South area, the presen

24. Um estudo sobre regulaÃÃo do setor elÃtrico no Brasil e preÃos de Ramsey-Boiteux: o caso do estado do Cearà / A study on regulation of the electric sector in Brazil and prices of Ramsey-Boiteux: the case of the state of the CearÃ
The privatization process initiated in the 90âs had in the sector of electric energy, which has characteristics of natural monopoly in the transmission and distribution sectors, its great booster. These privatizations brought together the need of the regulation of the electric sector, in a way to benefit not only the consumer, but also the companies that we
