4. Controle linear de maximo torque do motor sincrono de imãs permanentes interiores / A linear maximum torque control of the interior permanent magnet synchronous motor
In this work is presented the linear maximum torque control of an interior permanent magnet synchronous operating in the constant torque and field weakening ranges. The constant torque control is implemented by using the maximum torque per Ampére curve of the motor. The terminal stator voltage remains constant along the field weakening range due to the arma

5. The studies of International Comparative Education in the Dissertation and Thesis Databank of CAPES from 1987 to 2006 / Os estudos de educação comparada internacional no banco de dissertações e teses da CAPES no período de 1987 a 2006
The intensification of the globalization process, the weakening of the National States with the strengthening of supra-national identity territories and the advent of the information technologies favored a more intense interchange between countries and gave a new life to comparative studies. This dissertation aims at analyzing what has been produced in Brazi

6. Acionamento vetorial de motores de indução trifásicos com enfraque-cimento de campo e maximização do conjugado por ampère
This work investigates the operation of three phase induction motors in field weakening and high speed regions. Maximum torque per ampère is imposed by using an indirect vector control strategy. Mathematical models that accounts for magnetic saturation is used for simulations and adjustment of controllers used in control algorithm. The driving structure is

7. Efeitos da fragilização dos papéis parentais em determinados comportamentos de crianças no ambiente escolar, na contemporaneidade / Effects of the Weakening of parental role in some behaviors of children in the school environment, in contemporaneity
The phenomenon of the Weakening of parental role, in contemporary family, nowadays, is related to difficulties that parents have in educating their children, which is due to insecurity and doubts about the position that they should assume before their children. Facing that, this dissertation aimed to understand the correlation between parents who showed char

8. Flexibilizar, vulnerabilizar e precarizar : efeitos da desestruturação da vida dos trabalhadores brasileiros, sob as ordens do "mercado"
The research was based on the assumption that the uncertainty has been used as a technique, an instrument of power of the current stage of speculative capitalism to manufacture a docile mass subject to the most intense exploitation of the capital, living under uncertain conditions that produce a strong sense of fear of the future. Fear, expressed in the perm

9. Da escolarização do esporte à esportivização da escola: tradição e espetáculo nos Jogos da Primavera de Sergipe 1964-1995).
The 20th century was highlighted by the growth of industry, by the economic transnationalization, by the bipolarity between capitalism and socialism, by the expansion of basic education in the midst of an economic barbarism. Specially the century of spectacle, a phenomena which, under the dynamics of modernity, shaped the comprehension of the world and the s

11. Burocratização e institucionalização das organizações de movimentos sociais: o caso da organização de prostitutas Davida
The discussion about the non-governamental organizations (NGO) has been developed more in the political-ideological field than in the academical-sociological one. Many have been the theories and ideological or doctrinarian formulations that try to interpret how NGO should develop in the world today and what should be their role in this contemporaneous contex

12. Magnetocaloric effect in UM2 and (U,R)Ga2 compounds / Estudo do efeito magnetocalorico em compostos UM2 e (U,R)Ga2
In this work we study the magnetocaloric effect in UM2 (M=Ga, Ge, Fe, Ni), U(Gal-xMx)2 and (Ul-yRy)Ga2 (M=AI, Ge, Si, Fe, Ni, Co, Pt and R=Dy, Er) which are ferromagnetic systems. The formation of the local moment in the UM2 ferromagnetic compound is important to obtain larger values for D S and D T. We calculated the magnetic properties and the EMC for UGa2
