Postcolonial Ghosts / Fantômes Postcoloniaux
2009
As liminal beings, ghosts seem particularly appropriate to define, question or challenge hybrid cultures where several, seemingly irreconcilable, identities coexist. The present volume wonders how they manifest themselves in the English-speaking world, and whether there is a specifically postcolonial kind of haunting. The 22 articles deal with textual, translational or historical ghosts, and take us to Canada, Australia, Africa, India or the Caribbean. Poems by Gerry Turcotte literally haunt the volume, which thus juxtaposes theory and practice in a dynamic and fruitful way.
Noise contribution to resonance phenomena and information propagation in non linear electronic networks
2015
This manuscript presents research aiming to show possible positive effects of deterministic and stochastic perturbations on the responses of different nonlinear systems. To that end, both numerical and experimental studies were carried out on two kinds of structures : an elementary electronic FitzHugh-Nagumo oscillator and an electrical line developed by resistively coupling 45 elementary cells. In the first section, the elementary cell characterization was undertaken in a deterministic regime. In the presence of a bichromatic stimulus, it is shown that when the low frequency component is subthreshold, its detection can be maximized for an optimal magnitude of the second component thanks to…
Le fantôme de Descartes
2012
Trop souvent, on considere l’histoire de la philosophie comme quelque chose de scolaire, qui n’eclaire pas la pensee. Or il en va tout autrement, puisqu’elle nous permet precisement de mieux contrer certains discours du monde contemporain, et d’echapper a l’enfermement du present. Comme le demontre l’exemple de la theorie du dualisme cartesien, qui permet de critiquer de maniere feconde l’approche reductrice des sciences cognitives.
Rois et spectres dans les pièces de Shakespeare
2019
International audience; Dans certaines de ses tragédies, les spectres royaux, convoqués par Shakespeare, reviennent. Nous nous pencherons sur le secret de famille transmis d'une génération à l'autre (dans "Hamlet") ou sur l’oracle rendu par les sorcières (dans "Macbeth"). Des lectures d’Arthur Gordon Craig, de Monique Banu-Borie, de Nicolas Abraham et Maria Torok viendront éclairer le statut du fantôme dans le théâtre de Shakespeare, entre rêve et réalité, présence et absence, incarnation et dépossession de soi.
Nonlinear resonances and some of their applications to information processing
2021
The study of resonance phenomena in nonlinear dynamical systems has drawn considerable attention for years. The most studied nonlinear resonance is undoubtedly the famous stochastic resonance, which consists of perturbing a nonlinear system with an appropriate amount of noise to enhance the detection of a subthreshold input signal. Since the introduction of stochastic resonance in the context of climate dynamics, it was later observed that a deterministic high frequency perturbation can replace noise leading to vibrational resonance. Even if this latter resonance was investigated in many areas of science for more than two decades now, it is still receiving attentions. It is the subject of t…
