Ce mémoire présente un point de vue basé sur la théorie des algèbres de Jordan pour faire une étude analytique, géométrique et topologique de certains espaces homogènes : espaces hermitiens symétriques, leurs frontières de Shilov et espaces symétriques causaux de type Cayley. <br />En particulier, nous passons en revue des résultats sur l'indice de Maslov, de Souriau et d'Arnold-Leray. Nous étudions aussi certaines propriétés de contractions et de compressions de ces espaces.<br />Le prolongement de la série discrète holomorphe est une partie importante du programme de Gelfand-Gindikin. Dans ce contexte, nous étudions les espaces de Hardy des fonctions holomorphes sur certains domaines Stein. Nous donnons en particulier le lien qui existe entre ces espaces de Hardy et les espaces de Hardy classiques des fonctions holomorphes sur les espaces hermitiens symétriques.<br />En dernier lieu, nous étudions la conjecture de Helgason pour la frontière de Shilov des espaces hermitiens symétriques. Plus précisément, nous caractérisons l'image par de la transformation de Poisson des hyperfonctions et des fonctions $L^p$ sur la frontière de Shilov.

Esses métodos, dos quais o mais empregado é o de Hardy-Cross, fazem tão somente o balanceamento da rede, deixando a cargo da experiência do projetista a busca de um dimensionamento mais econômico. Neste trabalho será apresentado um método que utiliza técnicas de programação não linear para o dimensionamento económico de redes malhadas. Esse método é composto de duas etapas. Na primeira, as vazões e os diâmetros são considerados como variáveis de decisão, e na segunda etapa, as variáveis de decisão são os comprimentos dos segmentos dos trechos, com diâmetros constantes, e suas correspondentes vazões. Essa metodologia foi aplicada a duas redes encontradas na literatura, em que o dimensionamento já havia sido feito por outros métodos de otimização. Os resultados mostram que o método da programação não linear apresenta uma eficácia maior na busca do custo mínimo de uma rede, quando comparado com outras metodologias de otimização de redes malhadas estudadas. / The design complexity of looped networks has forced to use traditional trial and error methods to attain a solution for the problem. Those methods, where the Hardy-Cross method is the most known among them, only carry out energy and mass balance of the network without dealing with the system's cost, that is, nor estimating neither improving the system's cost. In this work, a method for designing economical looped networks based on nonlinear programming is presented. To reduce the number of variables and, probabily, improve the performance of the solution procedure, this method is composed of two stages to reach an optimal solution. In a first stage, a nonlinear programming technique is applied to determine the flows and diameters of the pipes connecting two nodes of the network. In a second stage are chosen which are the upper and lower values of the results attained at the first stage for each pipe segment, and a nonlinear programming technique is applied once more to determine the length of each diameter for each pipe segment along with its flow. In both stages the objective function was related to the cost of the pipes and pumping requirements. This method has been applied to two examples of looped networks, which have been used in the literature to illustrate the application of other optimization methods developed by other authors. The optimal solutions attained from the method presented herein have shown to be better than the ones resulting from the application of any other method, which were taken into account for comparison in this work.

A cathedral of the Church of England is the seat of the bishop and a centre of worship and mission. The history of this institution is followed from the English Reformation, which it survived, through to the Commonwealth, which it did not. Restored on the return of the monarchy, it then survived with little further trouble until the nineteenth century, when a lot of its income was diverted to the provision of churches and ministers for the populous urban and industrialised areas, which the Church could not fund in any other way. It was the subject of investigation by two Royal Commissions in the nineteenth century and three church-inspired commissions in the twentieth. These commissions stressed the links that should exist between cathedral, bishop and diocese, which the nineteenth century diocesan revival also encouraged, and suggested changes in instruments of governance to achieve this. Some proposals came to nothing, but others were brought into law. Unlike the Roman Catholic cathedral, the Anglican one never lost its autonomy. The religious situation in Britain today is considered in the light of some contemporary sociology and psychology, and it is recognised that the continued decline in the fortunes of the Church is tied up with the massive subjective turn which characterises contemporary culture. The cathedral has not shared the mistrust which faces the Church, and its various roles are discussed in the light of its continued hold on public affection. The conclusions reached are that, although the cathedral now has strong links with bishop and diocese, it should retain its independence within relationships of interdependence with them, to enable it to harness the popularity which it enjoys to remain a centre of worship, but primarily to concentrate on being a centre of mission. Appropriate ways of achieving that are discussed.

The discursive and critical positions of the ‘classic’ nineteenth-century novel, particularly the woman’s novel, in the field of adaptation studies have been dominated by long-standing concerns about textual fidelity and the generic processes of the text-screen transfer. The sociocultural patterns of adaptation criticism have also been largely ensconced in representations of literary women on screen. Taking a decisive twist from tradition, this thesis traces the evolution of representations of masculinity in the malleable characters of Rochester and Heathcliff in film and television adaptations of Charlotte Brontë’s Jane Eyre and Emily Brontë’s Wuthering Heights between 1939 and 2009. Concepts of masculinity have been a neglected area of enquiry in studies of the ‘classic’ novel on screen. Adaptations of the Brontës’ novels, as well as the adapted novels of other ‘classic’ women authors such as Jane Austen, George Eliot and Elizabeth Gaskell, increasingly foreground male character in traditionally female-oriented narratives or narratives whose primary protagonist is female. This thesis brings together industrial histories, textual frames and sociocultural influences that form the wider contexts of the adaptations to demonstrate how male characterisation and different representations of masculinity are reformulated and foregrounded through three different adaptive histories of the narratives of Jane Eyre and Wuthering Heights. Through the contours of the film and television industries, the application of text and context analysis, and wider sociocultural considerations of each period an understanding of how Rochester and Heathcliff have been transmuted and centralised within the adaptive history of the Brontë novel.
