Since about three decades ago, the networking services (water, energy, transport and telecommunications) are the subject of studies and mainly reforms (liberalization, privatization and concessions to private companies, etc.) and also an important economic policy issue. However the possible effects of these reforms on the fragmentation or integration of urban societies are still poorly studied, although some studies (mainly on developing cities) support the thesis that there would be a growing urban fragmentation, reinforced by the dominant modes of implementing reforms network services. One of the most important theses about the subject is in a relatively recent development of the English authors Stephen Graham and Simon Marvin (2001). Their work generalizes the motion of fragmentation (splintering Urbanism) to all network services and a set of economic regions in the world. While this thesis presents consistency and validity - since it is known that the application of models of decentralization and liberalization of services has an effect on the fragmentation - the position of fragmentation due to centralized networks is inside a new analysis framework and still incomplete considering the absence of more empirical evidence. The thesis of fragmentation from centralized networks suggests that powerful factors are contributing to the disintegration of infrastructure, favoring the fragmentation of the social structure and material of cities. In fact, this breakdown of infrastructures makes possible many strategies of evasion; they are addressed to connect powerful users and valorized spaces, preventing the connection with less powerful users and poor spaces. These processes lead to the creation of spaces from different social networks, resulting in social elites living every day in places disconnected from the urban structure of the set (in gated communities, new complex people and other planned communities), as well as the lower classes, but the latter with the worst conditions. The main hypothesis of the "splintering Urbanism" argues that network services have an integrated character and are precisely the privatization and liberalization of services that contribute to the breakdown of network infrastructure and urban fragmentation feed. The control of networks from powerful coalitions of actors, separation and segmentation boost infrastructure in different network elements and service pack (2001: 141). This separation would occur across strategies "bypass" or "wrap" seeking to connect users, valuable or powerful places, and through discarding or dodge weaker users and worthless places. Our thesis "Urban Fragmentation through technical networks," confirms and reinforces the thesis made by Graham & Marvin, across expounding on the Cochabamba Bolivian context, a set of technical networks of small-scale or micro decentralized networks which are managed by autonomous social organizations that also fragment the territory without the need for "by pass" and the socio-spatial differentiation, but through the realization of strategies linked to autonomous administration and management of common and basic goods like water. This thesis demonstrates the existence of processes of spatial dislocation and loss of solidarity (main evils of urban fragmentation) across the dynamics of technical devices and decentralized networks infrastructure services from private-community water and small scale. However, our work describes in its urban development, territorial and environmental problems inside the phenomenon. The paper first presents a set of theories that attempt to explain the fragmentation and its particularities, then describes the socio-spatial formation of the study area whose characteristics allow this type of phenomenon, to arrive to a section that exposes all the particularities of the management water from public and local actors, analyzed from the environmental logic of urban water cycle, including the specifics of the main stage of study of this thesis, the municipality of Quillacollo in Cochabamba. From a spatial perspective, the thesis exhibits the characteristics of urban fragmentation across technical networks, exposing the details related to the organization of urban space as a result of processes of spatial dislocation, loss of solidarity and exercise of territoriality in small networks. It is concluded in a discussion about the validity of the strategies in terms of access to the resource, the possibilities of intervention and reflections about the power relationships among fragments and for water control. Finally, as a supplement, urban fragmentation through small technical networks, also allows to display the tensions between two ways of managing the territory (centralized view from the public sector and decentralized vision from local communities) highlighting the uncomfortable and marginalized urban planning position, but challenging the urbanism to recover to action on the highly fragmented contemporary cities with complex scenarios of governance and sometimes rare or endangered resources.

Le but de ce travail est l’étude de l’objet scientifique entendu comme totalité constituée à travers la mise en relation de différentes visualisations expérimentales, voire de configurations fragmentaires et instables. Dans ce cadre, une première acception de « fragment » concerne une organisation de données issue de paramètres sous contrôle et répétables. Il s’agit d’une organisation provisoire et partielle, qui se manifeste en tant que visualisation, parmi d’autres, d’un objet de recherches qui est en train de se transformer, à travers différentes étapes expérimentales, en un objet scientifique tout court, à savoir en un objet stable et reconnu par une communauté. Nous ferons également l’hypothèse que les différents modes d’existence de l’objet scientifique (virtualisation, actualisation, réalisation, potentialisation) constituent une deuxième acception de « fragment » : ces modes peuvent être considérés comme des « fragmentations » en différents statuts existentiels de l’objet de la science (constitution des hypothèses, expérimentations diverses, modélisation, etc.).

Actuellement, la théorie des frames est utilisée principalement en analyse du signal. La découverte du lien entre les frames et les ondelelettes et les bases de Riesz a marqué le point de départ de l’essor de la théorie des frames dans ce domaine. C’est dans le contexte de l’étude des séries nonharmoniques de Fourier que les frames ont été introduites par R.J. Duffin et A.C. Schaeffer en 1952 dans leur article intitulé "A class of nonharmonic Fourier series". Bien que la définition générale d’une frame sur un espace de Hilbert soit déjà donnée dans cet article et qu’une théorie des frames en elle-même y soit déjà développée, les auteurs, concernés surtout par l’analyse nonharmonique de Fourier, y développent essentiellement la notion de frames d’exponentielles dans l’espace L^2(I), où I est un intervalle borné de R. Le résultat principal obtenu par Duffin et Schaeffer est une condition suffisante pour qu’une suite de nombres complexes génère une frame d’exponentielles. Ce résultat est basé sur un résultat reliant les suites de densité uniforme et les fonctions entières de type exponentiel. Duffin et Schaeffer auteurs ne présentant qu’une condition suffisante, ils laissent donc là un problème ouvert : la caractérisation des frames d’exponentielles. Une résolution partielle de ce problème n’a été donnée que bien plus tard par Jaffard. En effet, en 1991, dans son article "A density criterion for frames of complex exponentials", Jaffard propose une condition nécessaire et suffisante pour qu’une suite réelle génère une frame d’exponentielles. Le but de ce mémoire est de présenter ces résultats. [less ▲]

A framework is developed for studying the implementation process, as a stepwise process in which an abstract specification is successively transformed to reach a final compilable specification adapted to the computer environment. In this context, an implementation relation is referred to as the relation which should link any ``valid'' implementation to its abstract formal specification. In other words, the implementation relation is intended to express formally the notion of validity. Our framework allows the exact characterization of the transformations which may take place at each step for a given implementation relation. This framework is essential for dealing with non-transitive implementation relations. In the second part of the paper, these results are exemplified in LOTOS on some existing relations, and an apparent paradox is presented. Some new results about these relations are also derived.

The implementation of the Water Framework Directive (EU 2000) requires a groundwater quality monitoring. It is used for characterisation of the 'good' chemical status of each groundwater body and for the restoration or protection purposes of those bodies already at 'good' status. Interpretative aspects are lying in the design of monitoring network and in the way of building global indicators. Attention is given here to the global chemical status of the groundwater bodies and to the role of diffuse pollution, much of which is brought via groundwater to surface water. Monitoring 'local' pollution associated with individual sites is not addressed. Groundwater bodies with different contrasted hydrogeology conditions, land use and topography have been considered to establish an approach for choosing an optimised monitoring network. Then, a quality assessment system has been developed and applied for qualifying the general status of each groundwater body. The use of non-dimensional indexes allows us to process with all kinds of chemical parameters in a normalised way and, by means of adequate aggregation rules, to qualify the general quality status of a groundwater body. The obtained diagnostic, even if not fully validated, is closely linked to the pragmatic objectives contained in the EU Water Directive. [less ▲]
