25. Otimização das formas de cascos de deslocamento em relação a sua resistência ao avanço. / Displacement hull optimization regarding to ship wave resistance.
Due to an increasing necessity of building new vessels, whether by new orders or fleet renewal, the development of computational programs that could allow optimization of hull shapes is always helpful, saving project time and ensuring better performance at sea. Thus, the development of a synthesis procedure that allows obtaining shapes with better performanc

26. Sincronização de uma classe de sistemas não-lineares acoplados com aplicações em sistemas elétricos de potência / Synchronization of a class of coupled non-linear systems with applications in electric power systems
Synchronization of a class of coupled non-linear systems is studied in this work. From the theoretical point of view, we present synchronization results that provide sufficient conditions on the vector field and estimates of the coupling parameters that guarantee synchronization. Differently from the existing approaches in the nonlinear systems literature, o

27. DEMOCRACIA PARTICIPATIVA E DIREITO DE EDUCAÇÃO: A CONTRIBUIÇÃO DO ORÇAMENTO PARTICIPATIVO NA EFETIVIDADE DO DIREITO SOCIAL DE EDUCAÇÃO NO MUNICÍPIO DE BELO HORIZONTE/MG / PARTICIPATORY DEMOCRACY AND THE EDUCATION RIGHT: THE CONTRIBUTION OF THE PARTICIPATORY BUDGET IN THE EFFECTIVENESS OF THE SOCIAL RIGHT OF EDUCATION IN BELO HORIZONTE-MG CITY
The emergence of capitalism has made a divided society between social classes, which on grounds of conflict of interest brought within the social struggles between the owners or the means or production and the proletariat. The shock derived of this conflict has created historical politics conquests and new rights for the people. Thus, the capitalist producti

28. Influência da utilização do ABS na segurança veicular baseada na eficiência de frenagem e na probabilidade de travamento de roda / Influence if the ABS use on vehicular safety based on braking efficiency and on the probability of wheel lockup
The ABS (Antilock Braking System) is a supplementary system to the regular service brake system, which prevents the wheel lock in any braking situation, mainly in emergency braking maneuvers, and it will guarantee stability and steerability of the vehicle and reduces, in most of the situations, the stopping distance in relation to the regular brake system.

29. Controle robusto de sistemas de potência multimáquinas através de desigualdades matriciais lineares: abordagem por alocação de pólos e ajuste de estabilizadores de sistemas de potência. / Robust control of multimachine power systems through linear matrix inequalities: the pole placement approach with power system stabilizers adjustment.
The aim of this work is to elaborate robust control algorithms to power systems. The mathematical model employed to describe the multimachine power system is that used in small signal studies, and the main goal is to increase the damping of the critical eigenvalues of the system, guaranteeing its stability and performance in various operating conditions. To

30. Treinamento de redes neurais artificiais baseado em sistemas de estrutura variável com taxa de aprendizado adaptativa
This work presents new algorithms for training multilayer perceptron artificial neural networks based on stability properties of sliding mode variable structure systems. The main feature of the proposed algorithms is the adaptability of the gain (learning rate), which is obtained from each update step of the network weights, without the use of heuristics met

31. TIP OVER AND SLIPPAGE CONTROL OF MOBILE ROBOTIC SYSTEMS OVER ROUGH TERRAIN / CONTROLE DE CAPOTAGEM E DESLIZAMENTO DE SISTEMAS ROBÓTICOS MÓVEIS EM TERRENOS ACIDENTADOS
The use of mobile robots to monitor non-accessible environments has become increasingly common in the recent years. These tasks can be either autonomous, remote-controlled, or passenger-operated. When performed in rough terrain, it is necessary to guarantee mission safety, since many times it is impossible to send a rescue party for recovery. The hybrid envi

32. Development of topical formulations containing papain to wounds treatment. / Desenvolvimento de formulações tópicas contendo papaína para o tratamento de feridas
The present work evaluated by content of protein measurement, electrophoresis, proteolytic activity determination and verification of this activity stability, raw materials of papain obtained from two manufacturers. Gel formulations of Carbopol® 940, Natrosol® 250 HHR and Pluronic® F127, and containing 1% of papain, were developed and evaluated with regar

34. Obtaining a fluorescent and resistant hybrid yeast to the nystatin / Obtenção de levedura híbrida fluorescente e resistente a nistatina
Vats contamination by wild yeasts can harm the efficiency and the productivity of ethanol industrial production and there are not efficient methods to control this type of contamination. Easiness, speed and the low cost would be desirable characteristics for the control of yeasts that eventually contaminate the fermentation process. With this aim, TAVARES (1

35. Proteção ambiental e comércio: limites entre a defesa de objetivos legítimos e protecionismo disfarçado
The study of the relationship between trade and the environment requires, on the one hand, an analysis of the evolution of environmental regimes and, on the other, of the multilateral trade regime established after World War II. In both cases, it is possible to see that environmental issues have become intertwined with international trade. However, the relat

36. Controlador de carregamento de baterias para turbinas eÃlicas de pequeno porte
Electric energy is considered noblest of the forms of currently available secondary energy. It is difficult to imagine modern society without the advent of the electric energy and the ease and comfort it has brought. The technological advances that humanity has made throughout time have greatly contributed to the control and use of electric energy. In the el
