Prise en compte de la complexité de modélisation dans la gestion énergétique des bâtiments
No full textEnergy management for building has become a major issue this last decade because of its energy impact. Building energy management reduces energy wastes and enable a better matching between energy needs and grid capabilities. Different types of energy management systems are proposed in scientific literature, most of them with anticipation capacities.The first results do not really consider the complexity issue coming from the number of modeling elements and also coming from the diversity of energy management applications.This thesis proposes elements of solution to the complexity problem. The work started by analyzing the energy management system 'GHomeTech' and its adaptation to the complex building prototype CANOPEA. The issue of composition from elementary models is explored. A solution is proposed; it enables the reusability of elementary models. Aggregation and transformation into mixed integer linear programming optimization models is presented. The resulting tool has been validated on the CANOPEA project.Energy management is not limited to MILP optimization. Different types of applications are also used to provide other services: parametric estimation models to simplify the configuration of energy management systems, simulation for validation and prediction depending on pre-defined scenarios for example. This other dimension of complexity is discussed in a second part of the manuscript. Solutions for automatic rewriting of models are detailed. It relies on symbolic manipulations in different types of processing. Several examples of applications illustrating the automatic generation of models are presented.Du fait de son impact énergétique, la gestion énergétique dans le bâtiment est devenu un enjeu majeur ses dernières années, qu'il s'agisse d'encourager la sobriété énergétique ou de s'adapter aux besoins des réseaux énergétiques.

Writing from the shadowlands: how cross-cultural literature negotiates the legacy of Edward Said
No full textThis thesis examines the impact of Edward Said's influential work Orientalism and its legacy in respect of contemporary reading and writing across cultures. It also questions the legitimacy of Said's retrospective stereotyping of early examples of cross-cultural representation in literature as uncompromisingly 'orientalist'.
It is well known that the release of Edward Said's Orientalism in 1978 was responsible for the rise of a range of cultural and critical theories from multiculturalism to postcolonialism. It was a study that not only polarized critics and forced scholars to re-examine orientalist archives, but persuaded creative writers to re-think their ethnographic positions when it came to the literary representations of cultures other than their own. Without detracting from the enormous impact of Said, this thesis isolates gaps and silences in Said that need correcting. Furthermore, there is an element of intransigence, an uncompromising refusal to fine-tune what is essentially a binary discourse of the West and its other in Said's work, that encourages the continued interrogation of power relations but which, because of its very boldness, paradoxically disallows the extent to which the conflict of cultures indeed produced new, hybrid social and cultural formations.
In an attempt to challenge the severity of Said's claim that 'every European, in what he could say about the Orient, was consequently a racist, an imperialist, and almost totally ethnocentric', the thesis examines a number of different discursive contexts in which such a presumption is challenged. Thus while the second chapter discusses the 'traditional' profession-based orientalism of nineteenth-century E. G. Browne, the third considers the anti-imperialism of colonial administrator Leonard Woolf. The fourth chapter provides a reflection on the difficulties of diasporic 'orientalism' through the works of Michael Ondaatje while chapter five demonstrates the effects of the dialogism used by Amitav Ghosh as a defence against 'orientalism'. The thesis concludes with an examination of contemporary writing by Andrea Levy that appositely illustrates the legacy of Said's influence.
While the restrictive parameters of Said's work make it difficult to mount a thorough-going critique of Said, this thesis shows that, indeed, it is within the restraints of these parameters and in the very discourse that Said employs that he traps himself. This study claims that even Said is susceptible to 'orientalist' criticism in that he is as much an 'orientalist' as those at whom he directs his polemic
Etudes de l’impact Environnemental de la Centrale Electrique Thermique de Cap-Djinet
No full text81 p. : ill. ; 30 cmLa centrale électrique de Cap-Djinet est une centrale thermique à vapeur qui utilise le gaz ou le fuel (gas-oil) comme combustible dans la chaudière pour la production de la flamme. Elle émet du dioxyde de soufre (SO2), des oxydes d'azote (NOx), du dioxyde de carbone (CO2), des cendres et des poussières. Elle est aussi génératrice de bruit émanant de toutes ses machines tournantes. Elle nécessite de grandes quantités d'eau de refroidissement qu'elle rejette à la mer à des températures généralement supérieures de plusieurs degrés par rapport aux températures normales. Tout cela, ne peut ne pas avoir d'impacts sur l'environnement. Des mesures des rejets des chaudières dans l'air et du niveau des nuisances sonores ont été réalisées pour évaluer leurs effets sur le personnel de la centrale, toute la zone environnante, et la population limitrophe à la centrale, cela constitue donc l'objectif de notre travail. Notre étude consiste d'abord, à présenter la centrale, son mode de fonctionnement, recenser ses différents rejets dans l'atmosphère et dans la mer, évaluer les effets que représente toute cette pollution générée par ces rejets. Enfin, nous avons essayé d'exploiter les résultats des mesures pour illustrer l'effet de la pollution que constituent ces rejets et ces nuisances sonores sur l'environnemen
What said the economic theory about Portugal. Another approach
No full textWith this work we try to analyse the agglomeration process in the Portuguese regions, using the New Economic Geography models. This work aims to test, also, the Verdoorn Law, with the alternative specifications of (1)Kaldor (1966), for the 28 NUTS III Portuguese in the period 1995 to 1999. It is intended to test the alternative interpretation of (2)Rowthorn (1975). With this study we want, also, to test the Verdoorn´s Law at a regional and a sectoral levels (NUTs II) for the period 1995-1999. The importance of some additional variables in the original specification of Verdoorn´s Law is yet tested, such as, trade flows, capital accumulation and labour concentration. This study analyses, also, through cross-section estimation methods, the influence of spatial effects in productivity in the NUTs III economic sectors of mainland Portugal from 1995 to 1999, considering the Verdoorn relationship. The aim of this paper is, yet, to present a contribution, with panel data, to the analysis of absolute convergence and conditional of the sectoral productivity at regional level (from 1995 to 1999). The structural variables used in the analysis of conditional convergence is the ratio of capital/output, the flow of goods/output and location ratio.new economic geography; Verdoorn law; convergence; cross-section and panel data; Portuguese regions

What said the new economic geography about Portugal? An alternative approach
No full textWith this work we try to analyse the agglomeration process in Portugal, using the New Economic Geography models, in a linear and in a non linear way. In a non linear way, of referring, as summary conclusion, that with this work the existence of increasing returns to scale and low transport cost, in the Portuguese regions, was proven and, because this, the existence of agglomeration in Portugal. We pretend, also, in a linear way to explain the complementarily of clustering models, associated with the New Economic Geography, and polarization associated with the Keynesian tradition. As a summary conclusion, we can say which the agglomeration process shows some signs of concentration in Lisboa e Vale do Tejo and the productivity factor significantly improves the results that explain the regional clustering in Portugal. The aim of this paper is to analyze, yet, the relationship between the regional industry clustering and the demand for labor by companies in Portugal. Again, the results are consistent with the theoretical developments of the New Economic Geography, namely the demand for labor is greater where transport costs are lower and where there is a strong links "backward and forward" and strong economies of agglomeration.new economic geography; linear and non linear models; Portuguese regions
