Full textThe digital growth of the construction industry led to BIM (Building Information Modeling). Developed for buildings, BIM is later used on linear infrastructure projects. Such projects require end-to-end control of information. PLM (Product Lifecycle Management) supports digital continuity in the manufacturing industry. Studies evaluate the relevance of a complementary use of the BIM and PLM approaches for linear infrastructure projects. With an adaptation of methods used for building construction, those studies are mostly restricted to the implementation of data repositories. This makes it difficult to consider the infrastructure post-construction phase, where the 3D model is no longer a digital model, but a digital twin. This research work consists in developing a strategy for the design, the implementation and the operations and maintenance of a linear infrastructure. The digital twin of the infrastructure is the target of our approach. It will take into consideration not only BIM and PLM methodologies, but also any other data source positioning the infrastructure in its geographical environment. Data aggregator, our digital twin should make it possible to manage the lifecycle of a linear infrastructure. This system is tested on a specific linear infrastructure, a level crossing. Digital continuity and data traceability are important factors for those constructions. Through the digital twin, our proposal helps to follow the data, and thus to link operational data to the design and construction data of the linear infrastructure

"Matérialité et gouvernance du système sociotechnique très haut débit à Dakar (Sénégal) : vision stratégique de l’infrastructure numérique, planification métropolitaine et chantiers de construction." Electronic Thesis or Diss., Université Gustave Eiffel, 2025. http://www.theses.fr/2025UEFL2009.
Full textThis thesis analyzes the development of a very high-speed socio-technical system (fiber optic network and data centers) and the urban transformations of a West African metropolis, questioning the conditions and modalities of a “digital urbanism” in Dakar (Senegal). The aim is to understand how digital infrastructure and urban spaces shape each other, and to propose a reading based on materiality rather than overhanging an inert materiality-support.Drawing on work from urban studies and social approaches to technology inspired by Science and Technology Studies (STS), the investigation focuses on the socio-political, socio-technical and territorial dimensions of very-high-speed infrastructure deployment, which it analyzes at three scales, corresponding to distinct spheres of action and temporalities, and in different types of intra-urban spaces. Using a qualitative methodology (interviews, participant observation, mapping), the thesis demonstrates the ambivalent relationship between the privatized development of the very-high-speed socio-technical system and socio-spatial inequalities. On a national and metropolitan scale, it highlights the links between urban planners and powerful international telecoms operators, and their respective influence on metropolitan digital planning in a context marked by neoliberal policies. At the street level, it analyzes the role of network engineers and technicians, highlighting the role of material contingencies, informality and socio-technical “bricolage”, as well as the role of “street-level” technical expertise in the material development of very high-speed infrastructure, through a study of construction sites and “on-the-spot” work. Analysis of the governance of deployment, coupled with that of urban materiality and metropolitan socio-spatial evolutions, has enabled us to qualify a digital urbanism that differs according to urban profiles. However, while insisting on the decisive weight of telecoms operators and the insufficient prescription and regulation capacity of public authorities, the thesis identifies self-regulation mechanisms that are sometimes beneficial to the general interest, and partial catch-up mechanisms in certain less “attractive” neighborhoods. These results lead us to qualify the effects of the “privatization” of digital development on urban fragmentation, and suggest elements of reflection for the public reengagement of a thought and practice of urban digital planning in Dakar
Kaabi, Faouzi. "Modeling and enhancement of wireless access and mesh infrastructure vehicular networks." Nice, 2010. http://www.theses.fr/2010NICE4082.
Full textA major technological breakthrough to improve road safety and traffic efficiency will be cooperative communications for transports systems. Through the use of wireless communications, cooperative systems will allow the dynamic exchange of messages between transportation system such as vehicle-to-vehicle (V21) and velicle-to-infrastructure (V21) communications. Cooperative vehicular systems are composed by Road Side Units (RSUs) and On Board Units (OBUs). OBUs provide network connectivity to the users and are inside their cars whereas the RSUs are fixed and deployed equipment on the public roads. The RSUs can be connected to each other and to the Internet using Wireless Mesh Network backbone. We call “service level / access of the vehicular network” the network composed by the RSUs and the OBUs and we call “backbone level / infrastructure of the vehicular network” the network connecting the RSUs to the Internet. In this thesis, we develop several contributions to improve the vehicular network performances at both service level and backbone level. For the service level, 802. 11p defines a control frequency channel for control and most critical data packets and one or several service frequency channels for less critical packets. As a first step, we propose an analytical model for the 802. 11p operations in the control frequency. It captures all suggested enhancements important for exchanging data packets generated by road safety applications. The model is a simple tool that is able to reproduce expected results. This is an important step toward the improvement of vehicular networks performances. The model is then combined with optimization criteria for optimal placement of roadside units. For the backbone level, we conduct a rich study to identify what are the significant factors and mechanisms that have the most important impact on the WMNs backbone performances. We concluded that investigating on channel allocation and routing is the best answer to that issue. After that, we focused and classified the most interesting work are those proposing a common-layer design between MAC layer and network layer and are the mostly concerning a centralized manner. However, in a wireless environment, presenting centralized approach is not too realistic. Our contributions in this area concern the development of two interesting approaches to solve the addressed problem in distributed fashion
Lin, Trista Shuenying. "Smart parking : Network, infrastructure and urban service." Thesis, Lyon, INSA, 2015. http://www.theses.fr/2015ISAL0138/document.
Full textSmart parking, allowing drivers to access parking information through their smart-phone, is proposed to ease drivers' pain. We first spotlight the manner to collect parking information by introducing the multi-hop sensor network architecture, and how the network is formed. We then introduce the traffic intensity models by looking at the vehicle's arrival and departure probabilities, following the heavy-tailed distribution. We study the deployment strategy of wireless on-street parking sensor layouts. We define a multiple-objective problem and solve it with two real street parking maps. In turn, we present a Publish-Subscribe service system to provide good parking information to drivers. We illustrate the system with a vehicular network and point out the importance of content and context of a driver’s message. To evaluate the resilience, we propose an extended Publish-Subscribe model, and evaluate it under different unforeseen circumstances. Our work is based on the premise that large-scale parking sensors are deployed in the city. We look at the whole picture of urban service from viewpoint of the municipality. As such, we shed light on two main topics: the information collection on sensor deployment and an extended version of Publish-Subscribe messaging paradigm. Our work gives a guideline from network-related perspectives for city before launching a smart parking or any similar real-time urban service. It also provides a meaningful evaluation platform for testing more realistic datasets, such as real vehicle traces or network traffic

Full textThe Cultural heritage is now considered as a source of added value and, consequently, has become the subject of numerous digitization projects. These projects originate both from public research institutions and from private companies and they explicitly aim at the development of knowledge products for specific markets. However, despite guidelines found here and there, we still know almost nothing of the concrete ways in which what is presented as a new paradigm will be deployed. Does the enactment of techno-patrimonial valuation generate transformations in the definition of what counts as heritage? In the framework of Science and Technology Studies, my analysis is based on ethnographical work in the Montreux Jazz Digital Project led by the Lausanne Federal Institute of Technology (EPFL). This project is truly a laboratory for the enactment of the paradigm of techno-patrimonial valuation; its first aim is to impulse the development of knowledge products through the reformulation of the collection of audio-visual recordings produced in the framework of the Montreux Jazz Festival into a collection of 46 000 musical pieces which are deployed on screens from which their future is oriented. My analysis shows that this digitization process continues the long history of technologies of writing and accumulation. It renews more than it inaugurates the relationship between technology and heritage. The visibility of heritage and its possible transfer to technological realizations become the horizon of collective action. The modalities by which visibility is transferred, among which demonstration is central, act upon all the stages of the digitization process, even before the operations of numerical conservation. Finally, this study shows that patrimonial value may become wholly referred to its potential for innovation and visibility transfer; this development entails changes in our relationship to the past, which is reinterpreted in the light of a continuous technological present in which notions of conservation, transmission and memory are difficult to accommodate

Full textThis dissertation is concerned with a longitudinal study of a computer network technology referred to as the Commotion wireless MESH software, and the assemblages of actants that come into contact with it (such as people, objects, organizations, discourses, etc.). I argue that this apparatus produces different versions of itself that uniquely relates the concepts of agency, infrastructure and the Commons because it explicitly claims to be both technical and political within different socio-historical folds. By assuming such an overt political stance, it invites us to think through the notion of mediation in a new light (infrastructural mediation). My research methods reflect different interpretations of this software by seeking to understand whether this wireless mesh network technology represents a compromise solution to redefining the forces that constitute telecommunications infrastructure and its hold on the social bond. To do so, my dissertation expands on a particular ethnographic path which, “by the middle”, attempts to understand the ways in which the existence of a socio-technical system is established. I argue that the establishment of a socio-technical apparatus does not amount to pulling it out of thin air, but rather to make it become what it is. The findings reflect the successive trials and errors that go into this process of developing a sociotechnical and mediatic form that has yet to be recognized, while also shoring up the constitutive elements of a mediation process between the Commons and telecommunications infrastructure
Lachand-Pascal, Valentin. "Approche centrée activité pour la conception et l'orchestration d'activités numériques en classe." Thesis, Lyon, 2020. http://www.theses.fr/2020LYSEI089.
Full textThe quantity and variety of digital devices available in schools is constantly increasing. However, educational uses have not followed this evolution. The limited use of digital may be explained by the difficulty in creating digital activities. We propose to combine concepts from research related to the creation and conduction of educational activities in the classroom, as well as work related to the conduction of digital activities in a more general way. We present the contributions and limitations of these two conceptual frameworks for the management of digital educational activities. We conducted interviews with teachers to understand how they create their digital activities and how they conduct them. When conducting activities in the classroom, teachers mainly encounter technical problems (unstable network, hardware limitations) and have to adapt their plans to deal with these problems. We propose an adaptable architecture to solve the technical problems. Our architecture allows the conduction of digital activities by taking into account the different constraints: the activities work with or without connection, on the different devices present in the classroom, and the architecture adapts to the infrastructures of the schools. This architecture is materialized in Toccata, an orchestration system allowing the creation and implementation of digital activities in the classroom. Toccata implements the design recommendations we identified. Finally, we identified interaction strategies to help teachers in the management of digital devices in the classroom. Through observations of middle school classrooms, we identified two main classes of tasks: content sharing and remote control of devices. Using an elicitation study, we found that control tasks are easier to perform than content sharing tasks, especially using a device worn like a connected watch. We found that the selection of content sharing devices remained particularly complex in terms of interaction. Our results open new possibilities for managing digital devices in the classroom. However, work is still needed on sharing, reusing, and redesigning digital activities

Full textHow is the city developed by and with digital technologies? To answer this question, the thesis analyses in a single movement the urban consequences of the information and physical infrastructures of digital technology. To this end, it mobilizes the methodological and analytical frameworks of Infrastructure Studies, the sociology of techniques and innovation and the sociology of public problems. From an empirical point of view, it proposes to take a step back from the major mediatized experiments of the "smart city" to study more diffuse, everyday transformations generated by digital technologies. It consists of two case studies: on the one hand, it follows a programme to develop connected services to improve the accessibility of a Paris Region transport network for people with reduced mobility, and on the other hand, it analyses the discreet establishment of numerous data centres in Plaine Commune, in the north of the Parisian metropolitan area, and the resulting local unrest. The fieldwork includes several participating observations, about 40 interviews, a press review and the analysis of internal documents of the organizations. The thesis shows how the logic of immediacy, of "real time", generally at the centre of the promises associated with the digital city, requires an increased availability of workers, data and servers. Thus, in the transport company, projects to improve passenger service via smartphones confront station agents with the dual imperative of the face-to-face relationship and the alerts of the connected device. The cartographic data on which connected services are based, often taken for granted, require organizations to invent new collaborations to ensure their production and maintenance. The servers necessary for the functioning of the digital society are accumulated, protected and maintained in data centres, imposing buildings that are geographically concentrated, disrupt the environments in which they are located, disconcert elected officials and disturb residents. The logic of real time thus weighs on the social and spatial organization of cities, and invites us to rethink the urban development of digital infrastructures in terms of work, maintenance and the environment - unlike those, more commonly mobilized, of socio-technical imaginaries, promises of optimization and urban models
