Em nome da cidade vencida: a São Luís republicana em José do Nascimento Moraes (1889 1920)

Cette dissertation a pour but d´analyser la ville de São Luís do Maranhão pendant la Première Republique, d´après le roman Vencidos e Degenerados, de José do Nascimento Moraes, publié en 1915. À partir des rapports entre l´Histoire et la Littérature, nous nous intéressons à la façon dont l´auteur écrit l´histoire d´une ville qui, après la fin de l´esclavage et l´installation de la Republique, conserve des anciens préjugés de race et reste plongée dans l´immobilité economique. Le roman fait partie d´un ensemble d´oeuvres scientifiques et littéraires d´une géneration connue sous le nom de Novos Atenienses (nouveaux athéniens), laquelle discutait la crise économique et culturelle vécue par le Maranhão au tournant des XIXe et XXe siècles. Le discours formulé par les nouveaux-athéniens comprennait des eléments nostalgiques associés au culte des lettres envisageant la conquête de la réconaissance littéraire et le désir d´adapter la ville de São Luis aux modèles de progrès et modernisation de la période républicaine. Dans ce contexte, Moraes introduit les thèmes liés à la discrimination raciale qui demerait après la fin de l´esclavage, qu´il considérait un obstacle au progrès de la capitale de Maranhão, et aussi la cause des pérsecutions littéraires dont il était victime. On a analisé le roman en cherchant compreendre les rapports entre les individus et les rapports qui´ils entretienent avec les spaces de la ville, à partir de questions d´ordre littéraire, raciale et urbaine. En guise de conclusion, la narration de l´oeuvre est dévellopée de façon que la ville, peuplée de gens de couleurs, sert à legitimée l´oeuvre littéraire de Moraes, dont le nom a été oublié dans les principaux cercles littéraires de la capitale pendant la période examinée

O Bairro da Ribeira como um palimpsesto: dinâmicas urbanas na Cidade de Natal (1920-1960)

As cidades são textos. Textos escritos pelas sociedades que compõe os espaços. A partir dessa perspectiva, propõe-se aqui uma leitura do bairro da Ribeira Natal/RN. Esse espaço se consolidou no início do século XX como centro comercial e cultural da capital potiguar, lugar de ação e de interação da Zona Central desta sociedade, espaço de inscrição dos signos da modernidade e do progresso então em voga. Contudo, com o decurso do tempo e as transformações por ele exigidas, o panorama da Cidade de Natal sofreu intensas modificações e o bairro da Ribeira foi relegado à margem desse processo, o que culminou na desvalorização, segregação e, posteriormente, na degradação do seu espaço, que se tornou um palimpsesto. Ao abordar a dinâmica urbana que se processou no bairro da Ribeira, esta pesquisa dividiu o fenômeno em três fases distintas: valorização, transição e decadência

Notes on Newton-Euler formulation of robotic manipulators

The equations corresponding to Newton-Euler iterative method for the determination of forces and moments acting on the rigid links of a robotic manipulator are given a new treatment using composed vectors for the representation of both kinematical and dynamical quantities. It is shown that Lagrange equations for the motion of a holonomic system are easily found from the composed vectors defined in this note. Application to a simple model of an industrial robot shows that the method developed in these notes is efficient in solving the dynamics of a robotic manipulator. An example is developed, where it is seen that with the application of appropriate control moments applied to each arm of the robot, starting from a given initial position, it is possible to reach equilibrium in a final pre-assigned position.

Os marcos da paisagem da cidade no contexto da trama urbana de Natal/RN: um estudo a partir do Morro do Careca, o Midway Mall, o Pórtico dos Reis Magos e a Ponte Newton Navarro

The present work is a study on the functions performed by landmarks landscape Natal / RN in the urban fabric, in the case of Midway Mall, the Portico dos Reis Magos, the Morro do Careca and Newton Navarro Bridge. For such goals established itself as analyze the functionality of the milestones presented here in the urban fabric; discuss the importance of these landmarks of the city landscape in the process of urbanization of Natal, and identify and spatialize actions related to the use of territories where are located landmarks, discussing their reflections. To achieve these goals we chose to use as a literature search procedures, the problematic concept, working with oral sources, and reading speechless. To support this research the main concepts were worked landscape, city, landmark, public space, circuits, among others. After going over the theory, consistent with the empirical data, it appears that the landmarks studied here have different functions and features, but all carry different forms of fascination for the public and visitors to the city, and every man your way, influence the public space, land speculation and feature importance in the process of urbanization of Natal

Bi-Lipschitz A-triviality of map germs and Newton filtrations

Bi-Lipschitz G-triviality and Newton polyhedra, G = R, C, K, R-V, C-V, K-V

In this work we provide estimates for the bi-Lipschitz G-triviality, G = C or K, for a family of map germs satisfying a Lojasiewicz condition. We work with two cases: the class of weighted homogeneous map germs and the class of non-degenerate map germs with respect to some Newton polyhedron. We also consider the bi-Lipschitz triviality for families of map germs defined on an analytic variety V. We give estimates for the bi-Lipschitz G(V)-triviality where G = R,C or K in the weighted homogeneous case. Here we assume that the map germ and the analytic variety are both weighted homogeneous with respect to the same weights. The method applied in this paper is based in the construction of controlled vector fields in the presence of a suitable Lojasiewicz condition. In the last section of this work we compare our results with other results related to this work showing tables with all estimates that we know, including ours.

Cultura pedagógica e formação de professores: a biblioteca da escola normal de Piracicaba (1911-1920)

Cet article a pour objet la Bibliothèque de l'École Normale de Piracicaba, à l'intérieur de São Paulo, entre les années 1911 et 1920, parce qu'elle représente un lieu de formation d'enseignants et organisation de culture pédagogique. Cette Bibliothèque qui a été constituée au long du cycle de vie de l'École Complémentaire de Piracicaba (1896-1911) et officialisée à partir de 1911 aura le rôle d'organiser et disséminer une certaine culture pédagogique en raison de sélectionner, trier et distribuer un ensemble de connaissances propres à la profession enseignante. Elle symbolise un espace de formation de l'enseignant de l'École Normale et de l'élève-lecteur. L'étude de la culture pédagogique se concentre sur l'analyse de cette bibliothèque.

Catolicismo e casamento civil na Cidade de Goiás: conflitos políticos e religiosos (1860-1920)

Este artigo analisa a atuação do clero no sentido de normalizar o comportamento das pessoas por meio da celebração do matrimônio na cidade de Goiás, no período de 1860 a 1920, sendo que as normas católicas tinham por objetivo implantar um catolicismo ultramontano tridentino. Assim, o clero ultramontano procurava moralizar a vida privada do fiel e também evitar a adesão deste ao casamento civil, sobretudo após a aprovação do Decreto n. 181, de 24 de janeiro de 1890, que o estabeleceu no País.

Cytotaxonomic analysis of Brazilian species of the genus Amazona (Psittacidae, Aves) and confirmation of the genus Salvatoria (Ribeiro, 1920)

The karyotypes of 12 species of Psittacidae of the genus Amazona were studied: A. aestiva, A. amazonica, A. brasiliensis, A. autumnalis, A. farinosa, A, festiva, A. kawalli, A. ochrocephala, A. pretrei, A. rhodocorytha, A. vinacea and A. xanthops. The metaphases were obtained using a short term culture of leather pulp. Eleven of the twelve analyzed species were karyotypically homogeneous, with only a few divergences in chromosomes 2 and 3. The species A. xanthops showed large karyotypic differences compared to the genus Amazona. Consequently, the genus Salvatoria (Ribeiro, Rev. Mus. Paul. 12: 1-82, 1920) was confirmed, and A. xanthops renamed Salvatoria xanthops. The study showed the chromosomic conservation of the genus Amazona and the need for further taxonomic studies of the karyotype of the Psittacidae.

A new approach to the solution of the optimal power flow problem based on the modified Newton's method associated to an augmented Lagrangian function

This paper presents a new algorithm for optimal power flow problem. The algorithm is based on Newton's method which it works with an Augmented Lagrangian function associated with the original problem. The function aggregates all the equality and inequality constraints and is solved using the modified-Newton method. The test results have shown the effectiveness of the approach using the IEEE 30 and 638 bus systems.
