Search for Multimessenger Sources of Gravitational Waves and High-energy Neutrinos with Advanced LIGO during Its First Observing Run, ANTARES, and Ic…
2019
[EN] Astrophysical sources of gravitational waves, such as binary neutron star and black hole mergers or core-collapse supernovae, can drive relativistic outflows, giving rise to non-thermal high-energy emission. High-energy neutrinos are signatures of such outflows. The detection of gravitational waves and high-energy neutrinos from common sources could help establish the connection between the dynamics of the progenitor and the properties of the out¿ow. We searched for associated emission of gravitational waves and high-energy neutrinos from astrophysical transients with minimal assumptions using data from Advanced LIGO from its first observing run O1, and data from the ANTARES and IceCub…
Peut-on discuter de la frontière franco-allemande avec un ordinateur ?
2019
Le rôle de la frontière intra-européenne a fortement évolué au cours du temps, notamment à travers la création de l’espace Schengen (1990) ou encore de la signature de différents traités (Maastricht 1992, etc.). Auparavant appréhendée comme une barrière empêchant et/ou contrôlant les passages, elle est devenue une zone d’intégration, un espace entre deux pays dont la culture, la langue, voire la règlementation sont différentes, mais qui tend vers la volonté d’estomper ces limites (développement de réseaux favorisant les mobilités, l’uniformisation du système monétaire, etc.). Malgré la disparition des contrôles aux frontières et une plus grande mobilité des populations, des différentiels su…
La fabrique des espaces sociaux. Identités, action, politique
2020
International audience; Espaces de vie, de travail, de loisirs, ou plus largement espaces d'engagements divers : les hommes évoluent dans des lieux multiples. Ces "espaces sociaux" (physiques ou symboliques, restreints ou vastes, d'hier et d'aujourd'hui) sont l'objet de l'ouvrage, qui étudie la manière dont les individus vivent l'espace, le perçoivent et y développent leurs expériences. Au fil des chapitres, et à travers le regard de chercheurs issus de diverses disciplines (histoire, sociologie, sciences juridiques et politiques, socio-psychologie, urbanisme et aménagement du territoire), on visite tout d'abord les espaces du quotidien, où se construisent les identités ; les espaces d'inte…

Les commissions de quartier à l’heure de l’engagement écocitoyen, à Dijon : entre communication stratégique publique locale et construction d’un espa…
2018
This doctoral thesis in Information and Communication Science explores the question of eco-citizen commitment in the neighborhood commissions of Dijon. Many academic or more popular publications in different fields of research (Information and Communication Science, social and environmental psychology, political science, law, philosophy, ecology, etc.) have addressed this issue in recent years. Once the actors of the question had been defined (the inhabitants, elected officials, technicians, representatives of structures and associations, etc.), it was possible to study different instances of participatory democracy in Dijon. The following question ensued : "How are the neighborhood commiss…
Integrable systems, Frobenius manifolds and cohomological field theories
2022
In this dissertation, we study the underlying geometry of integrable systems, in particular tausymmetric bi-Hamiltonian hierarchies of evolutionary PDEs and differential-difference equations.First, we explore the close connection between the realms of integrable systems and algebraic geometry by giving a new proof of the Witten conjecture, which constructs the string taufunction of the Korteweg-de Vries hierarchy via intersection theory of the moduli spaces of stable curves with marked points. This novel proof is based on the geometry of double ramification cycles, tautological classes whose behavior under pullbacks of the forgetful and gluing maps facilitate the computation of intersection…
Services supérieurs et recomposition urbaine
2000
Since the 1980s, we have observed an increasing tendency o f specialized services like producer services to leave their « natural habitat » in the center o f large met ropolitan areas in order to re loc at e in suburban zones. This phenomenon is particularly apparen t in North American citi es and seems to be occurring around certain French cities too. This paperinvestigates the forms taken by this new trend, and the reasons behind it. Taking economic geography and economics of cities as our theoretical basis, we first describe the main forces deter mining the agglomeration o f producer services and their preference for certain big cities. Agglomeration factors are to be looked for not only…
Vers des indicateurs locaux de performance énergétique : les étiquettes énergétiques territoriales. Une première approche à partir de l'estimation de…
2009
Global warming compels to investigate the decrease of green house gas effect emissions and so energy consumption reduction. At local scale, it leads to reach concrete goals regarding energy efficiency, which could be approached through the definition of indicators and guidelines for decision-makers. From the example of the city of Besançon (France), this research aims to define an original indicator, useful for planners. Considering a standardized mobility behaviour of inhabitants, we propose elements of methodology to measure the relative energy consumption of each zone based on their relative distance to the nearest shops, services and employment zones. The results display "zonal energy l…
Analysis of the role of communication devices shared on the internet - web 2.0 in the process of emergence of public sphere and democratization of Pa…
2013
In this thesis, the first study of its kind, the role of internet specially that of social networking shared devices on web 2.0 is analyzed in the process of emergence of Public Sphere – the notion introduced by Habermas, and ultimately in the process of democratization of civil society in Pakistan. Lawyers’ Movement (March 2007 – March 2009) of Pakistan is selected to analyze this role as this successful movement for the rule of law in the country is solely responsible for a fundamental democratic change in the democratic culture and socio-political set up of Pakistan by bringing a vibrant and active civil society in the lime light of country’s political and social life.The content in Paki…
Contribution to variational analysis : stability of tangent and normal cones and convexity of Chebyshev sets
2014
The aim of this thesis is to study the following three problems: 1) We are concerned with the behavior of normal cones and subdifferentials with respect to two types of convergence of sets and functions: Mosco and Attouch-Wets convergences. Our analysis is devoted to proximal, Fréchet, and Mordukhovich limiting normal cones and subdifferentials. The results obtained can be seen as extensions of Attouch theorem to the context of non-convex functions on locally uniformly convex Banach space. 2) For a given bornology β on a Banach space X we are interested in the validity of the following "lim inf" formula (…).Here Tβ(C; x) and Tc(C; x) denote the β-tangent cone and the Clarke tangent cone to …
