Petite histoire d'une expérience innovante dans l'académie de Dijon

2015

National audience; L'objet de cet article est d'interroger la manière dont une pratique innovante naît dans un établissement scolaire, s'installe et diffuse dans d'autres établissements. En prenant appui sur la sociologie de la « traduction », de même que sur une des propositions que de nombreux travaux sociologiques tendent à conforter - notamment celle selon laquelle les acteurs opérationnels résistent fréquemment aux prescriptions venues de leur hiérarchie -, il s'agira de faire émerger ce que sont les conditions nécessaires à la nais-sance d'une expérience innovante, ainsi qu'à l'installation et la diffusion des pratiques qui se rattachent à cette expérience. Le rôle du chef d'établisse…

Estimation des performances, test et contrôle des systèmes cyber-physiques employant des réseaux de communication non idéaux

2020

Wireless technology is a key enabler of the promises of Industry 4.0 (Smart Manufacturing). As such, wireless technology will be adopted as a principal mode of communication within the factory beginning with the factory enterprise and eventually being adopted for use within the factory workcell. Factory workcell communication has particular requirements on latency, reliability, scale, and security that must first be met by the wireless communication technology used. Wireless is considered a non-ideal form of communication in that when compared to its wired counterparts, it is considered less reliable (lossy) and less secure. These possible impairments lead to delay and loss of data in indus…

Moduli spaces of quasitrivial sheaves on the three dimensional projective space

2022

Let M(r,c_1,c_3,c_3) denote the Gieseker--Maruyama moduli space of semistable rank r sheaves on P^3 with the first, second and third Chern classes equal to c_1, c_2 and c_3, respectively. Maruyama proved that the space M(r,c_1,c_3,c_3) is a projective scheme. However, the geometry of such a scheme remains largely unknown, despite the efforts of many authors in the past four decades, and questions about connectedness, irreducibility, the number of irreducible components, and so on, remain open.When r=1 and c_1=0 (which can always be achieved after twisting by an appropriate line bundle), one gets that M(1,0,c_2,c_3) is isomorphic to the Hilbert scheme Hilb^{d,g}(P^3) of 1-dimensional schemes…

Direct experimental observation of mesoscopic fluorous domains in fluorinated room temperature ionic liquids

2017

Fluorinated room temperature ionic liquids (FRTILs) represent a class of solvent media that are attracting great attention due to their IL-specific properties as well as features stemming from their fluorous nature. Medium-to-long fluorous tails constitute a well-defined apolar moiety in the otherwise polar environment. Similarly to the case of alkyl tails, such chains are expected to result in the formation of self-assembled fluorous domains. So far, however, no direct experimental observation has been made of the existence of such structural heterogeneities on the nm scale. We report here the first experimental evidence of the existence of mesoscopic spatial segregation of fluorinated dom…

GESTION DES RISQUES ET DES INCERTITUDES L'EMERGENCE D'UN CONTRÔLE DE GESTION " PAR EXCEPTION "

2003

International audience; Le thème de la gestion des risques a été peu abordé en contrôle de gestion et le fonctionnement des outils traditionnels comme les budgets postulent une maîtrise des risques et des incertitudes. L'émergence de nouvelles approches en contrôle de gestion montre une évolution sur ce point.

Handover management in heterogenous mobile and wireless networks

2015

Since 1990, networking and mobile technologies have made a phenomenal unprecedented progress. This progress has been experienced on multiple fronts in parallel; especially on the application level and the user's needs one. This rapid evolution of the technology imposed a need for the existence of heterogeneous environments where the coverage is ensured throughout the different available networks. The challenge with such architecture would be to provide the user with the ability to navigate through the different available networks in a transparent and seamless fashion. However, the navigation among different types of networks is commonly referred to as vertical Handover. The IEEE 802.21 stan…

Towards a Reconstruction of Indo-European Culture: Semantic Functions of IE *men-

2003

The aim of this paper is to recover the semantic values involved in IE *men- in order to reconstruct some cognitive process modalities in regard to "Indo-European ideology" (Campanile 1992). After focusing on the apparent semantic split noticeable between Homeric Greek and Vedic in the uses derived from *men-, I argue for the presence of striking parallel paths using the methods of textual comparison. Then, the role of lexical nucleus' polysemy in originating the linguistic change is highlighted, without disregarding an Indo-European typological perspective within the realm of the so-called "basic lexicon" to which the root at issue belongs.
