L'accès des ménages aux services dans l'espace périurbain francilien
2008
The access of populations to services, out of the dense urban centres, is marked by the retreat of the services of proximity to which populations and local councillors appear particularly attached. However, in peri-urban spaces, this remote setting of the resources compared to the populations is the result of the generalized adoption of the automobile standard for mobility and accessibility. That has two effects: first a disintegration of the local offer, then a disintegration of the modal alternatives to the private car, because of relocalizations of services and populations which privilege car for their accessibility and call into question their access by other modes like public transport…
Spatial representations of future in Homeric Greek
2015
The aim of this paper is to investigate the space-time mapping of the future in Homeric Greek. It is widely accepted that the spatial adverbs πρόσσω ‘in front’ and ὀπίσσω ‘behind’ in the Homeric poems are used to portray temporal events located in a sequence of aligned entities that follow one after the other on the same path (Dunkel, 1983, p. 66). In such a temporal sequence, or Time-rp model, those adverbs are associated respectively to past and future events in a bipartite spatial representation of time, without involving a deictic ego-experiencer. After analyzing data from the Homeric poems in a cognitive linguistic perspective, it is found that some temporal uses of the preposition πρό…
Spaces, (Non-)Places, and Fluid Identities in Tim Winton’s Fiction
2021
One of the major issues addressed by postcolonial literature is identity crisis. In Australia, a multicultural country and a former settler colony, where the sense of belonging is particularly troubling, this literary theme has been exploited by writers to address the ambiguity of home and belonging. This article attempts to examine Tim Winton’s fiction and show how the writer explores the concepts of place and space to set his protagonists’ shattered selves in the postcolonial geography. The analysis of his fiction from the perspective of humanistic geography, Edward Relph’s concept of placelessness, and Marc Auge’s idea of non-place reveals that a simple categorization of Winton’s setting…

L’effet des pots acoustiques du caveau phonocamptique de la cathédrale de Noyon : analyse modale et performance chantée
2016
International audience; Au CFA de 2014 nous présentions le caveau phonocamptique de la Cathédrale de Noyon qui comporte, dans un espace souterrain réduit (15 m²), un nombre important de pots acoustiques (64). L’étude des livres liturgiques et de la documentation de la cathédrale (XVe-XVIIe siècles) ne permet pas à ce jour d’identifier le rôle et l’usage de ce caveau. Pourtant, les études archéologiques et acoustiques que nous avions présentées en 2014 montraient le soin qu’avaient pris les bâtisseurs pour élaborer cet espace : deux modèles de pots de hauteurs différentes, correspondant à deux fréquences moyennes proches d’une quarte musicale, une répartition choisie dans l’espace et un trav…

Partial Discharges in HVDC Cables - The Effect of the Temperature Gradient During Load Transients
2021
The paper investigates the role of the space charge accumulation phenomena in the inception of Partial Discharges (PD) in a defect within the bulk of the dielectrics of a High Voltage Direct Current (HVDC) cable. It is widespread accepted that the number of PD occurring in an HVDC cable during its lifetime is largely less than that under AC voltage stress. This is essentially due to higher values of the voltage between the conductor and the screen needed to trigger PD under a steady DC voltage than the same value under AC stress. Nevertheless, due to the dependency of the electrical conductivity of the insulation on the electric field and temperature, PD in HVDC cables is strongly influence…
Development of bidirectional dc-dc converters for hybrid power sources - Final Report
2018
A Bidirectional Isolated Full-Bridge Converter was designed, prototyped and tested. The device is intended to interface a Bank of Supercapacitors with a battery-powered bus, in order to boost the capability of supplying large power peaks. The converter was based on the Isolated Dual Active Bridge configuration. When driven by an external control voltage, it is capable of generating in both directions a train of current pulses, with 2kW peak power, for any battery voltage in the range 24-32V and for any supercapacitor voltage in the range 35-70V. Worst-case battery current was 70A. Pulse duration was 100ms with 50% duty cycle and 1 ms rise time.
L’intériorisation de l’espace: le désert chez Fromentin et Saint-Exupéry
2009
Cette étude se propose de tracer un parcours à travers l’analyse d’un désert mental et littéraire, réel et intériorisé. Il s’agit de comprendre une modalité de perception de l’espace du désert à travers l’expression artistique, notamment l’écriture de deux écrivains tels que E. Fromentin et A. de Saint- Exupéry. Premièrement nous allons aborder la question de la perception du désert en tant que paysage et par conséquent sa cristallisation en images transformant la réalité géographique des lieux. Le désert sera donc analysé en relation à la culture occidentale en tant que son même contrepoint ou bien en tant que terme de référence pour la définition de l’identité collective. Ensuite on abord…
