Digital socialization in a Territorial Intelligence case: The Fontaine d'Ouche area in Dijon (Burgundy, France).

2013

How to mobilize citizens around eco-responsible conducts? With the "Transition Towns MOVIDA" project (http://programme-movida.fr), we wish to identify levers related to a most sustainable consumption, in reference to the Transition initiated by Rob Hopkins. The present proposal consider all possible "socio-technical communicational" devices that can support the socio-ecological transition in a local area such as Fontaine d'Ouche in Dijon: reflexivity spaces (fear and hopes, actions and attitude) in a dialogical base for decisionmaking (at individual and collective level). What kind of ICT devices should allows inhabitants of the Fontaine D'ouche area to be more resilient? In this case, how …

The vehicle as a source and consumer of information : collection, dissemination and data processing for sustainable mobility

2014

Today, vehicles have become more sophisticated, intelligent and connected. Indeed, they are equipped with sensors, radars, GPS, communication interfaces and high processing and storage capacities. They can collect, process and communicate information related to their working conditions and their environment forming a vehicular network. The incorporation of communication technologies on vehicles garnered a huge attention of industry, government authorities and standardizations organizations and opened the way for innovative applications that revolutionized the automotive market with the main goals to ensure safety on roads, increase transport efficiency and provide comfort to drivers and pas…

Classification of spectra and search for biomarkers in prostate tumours from proton nuclear magnetic resonance spectroscopy

2010

Prostate cancer is the most common cancer in men over 50 years. Current detection methods either lack sensitivity or specificity or are unpleasant for the patient. Magnetic resonance spectroscopy allows the study of metabolism in vivo. The use of a high field machine (≥3T) has allowed us to dispense with the use of an endorectal coil, which is particularly uncomfortable for the patient. The objective of this thesis is to create an automatic method to detect cancer by processing data obtained through magnetic resonance spectroscopy MRS is a complex phenomenon, very sensitive to acquisition conditions. Firstly, we have studied how to improve and optimise signal acquisition. However, even with…

Relation entre transitivité et structure de communauté dans les réseaux complexes

2011

The relation between community structure and other topological properties in complex networks, has not been analyzed clearly. In this preliminary study, we explore experimentally the potential link between transitivity and community structure. We study the evolution of transitivity based on the quality of the community structure on artificially generated networks. Then we observe the evolution of community structure according to transitivity value. The results show a relationship between high transitivity and community structure. Additional analytical work is needed to identify the exact nature of this relationship.

From the Rhin-Rhône TGV to Rhin-Rhône "territory" : reticularity, mobility and territoriality in an intermediary space

2013

High-speed rail, destined to reduce the times-distances between major French and European cities, tends to push intermediary spaces into a rather unfavorable situation. Strongly polarized by the large urban centers that surround them, these intermediary areas are usually reduced to their sole status of transit areas. However, the Eastern tract, the first section of the LGV Rhine-Rhône project, through its regional dimension, constitutes a factor in the emergence of a territorialization process of the Rhine-Rhone area. Thus, the arrival of high speed rail is responsible for the creation of a network of cities that extends from Dijon to Basel. To address this territorial issue, a detailed ana…

Modeling of neuron-astrocyte interaction : application to signal and image processing

2022

The introduction of the tripartite synapse and the discovery of calcium wave propagation motivated our research to explore the potential of astrocytes as active components in brain circuits. For decades, astrocytes have been considered passive cells whose primary function is metabolic and structural support to neurons; however, recent physiological measurements suggest that astrocytes modulate neural communication, strengthen synaptic efficacy, enhance synchronization, and promote homeostasis. Inspired by these biological functions, this research aimed to implement astrocytes in artificial spiking networks for deep learning applications. First, we modeled the biological interaction between …

L'université à l'ère des réseaux sociaux: logiques, relations, communautés : le cas d'uB-link

2017

International audience; En 2011, l'Université de Bourgogne a expérimenté un réseau numérique baptisé uB-link, destiné à mettre en relation les membres de la communauté universitaire et à faciliter l'insertion professionnelle. Cet ouvrage revient sur la genèse, la méthode, la réalisation et les problèmes de ce projet.

Impacts écologiques des formes d'urbanisation : modélisations urbaines et paysagères

2015

The global increase of urbanization during the past decades have induced a progressive artificialization of natural environments. The building of transport infrastructures and new housings causes a landscape fragmentation in an irreversible way and a strong decrease of the connectivity of ecological habitats. Maintaining the functionality of ecological networks is becoming a major goal of sustainable urban planning policies. With a special focus on urban evolutions in the horizon 2030 in the urban area of Besançon in eastern France (residential development and road traffic evolutions), this thesis aims to assess the potential impact of urban forms on landscape connectivity of animal species…
