Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Recherche de fragments de plastique dans les sédiments benthiques du Léman

Luiz Felippe De Alencastro, Florian Faure

A growing number of studies focusing on microplastics (plastic particles smaller than 5 mm) show this issue affects all environmental matrices and compartments, and suspicions grow as to their toxicity. In this context, the Commission Internationale pour l ...

Goodwillie calculus and Whitehead products

Jérôme Scherer

We prove that iterated Whitehead products of length. (n+1) vanish in any value of an n-excisive functor in the sense of Goodwillie. We compare then different notions of homotopy nilpotency, from the Berstein-Ganea definition to the Biedermann-Dwyer one. Th ...

Unidirectional Cloaking Based on Metasurfaces with Balanced Loss and Gain

Romain Christophe Rémy Fleury

We prove that balanced loss-gain distributions provide an elegant path towards realizing loss-free unidirectional cloaks for objects much larger than the wavelength. By coating a scatterer with an ultrathin metasurface with balanced loss and gain, such as ...

Systems and methods for tracking interacting objects

Pascal Fua, François Fleuret, Engin Türetken, Xinchao Wang

Systems and methods for tracking interacting objects may acquire, with a sensor, and two or more images associated with two or more time instances. A processor may generate image data from the two or more images. The processor may apply an extended Probabi ...

Bimanual Compliant Tactile Exploration for Grasping Unknown Objects

Aude Billard, Nicolas Sommer, Miao Li

Humans have an incredible capacity to learn properties of objects by pure tactile exploration with their two hands. With robots moving into human-centred environment, tactile exploration becomes more and more important as vision may be occluded easily by o ...

Urban Experience: Remix of Attachments

Alexandre André Robert Rigal

I propose an essay for understanding how we experiment the fluidity, the density and diversity of the urban space. I purpose to reveal what I call the remix experience, that is to say the habit to of newness and otherness. This habit shows us the importanc ...

Near-Infrared Guided Color Image Dehazing

Sabine Süsstrunk, Chen Feng

Near-infrared (NIR) light has stronger penetration capability than visible light due to its long wavelength, thus being less scattered by particles in the air. This makes it desirable for image dehazing to unveil details of distant objects in landscape pho ...

Disambiguation Canvas: A Precise Selection Technique for Virtual Environments

Ronan Boulic, Anderson Maciel, Henrique Galvan Debarba

We present the disambiguation canvas, a technique developed for easy, accurate and fast selection of small objects and objects inside cluttered virtual environments. Disambiguation canvas rely on selection by progressive refinement, it uses a mobile device ...

Towards a Disambiguation Canvas

Ronan Boulic, Anderson Maciel

We present Disambiguation canvas, a technique for selection by progressive refinement using a mobile device and consisting of two steps. During the first, the user defines a subset of objects through the orientation sensors of the device and a volume-casti ...

The neural correlates of non-retinotopic processing in human visual cortex: a 7T fMRI study

Michael Herzog, Wietske Van der Zwaag, Gijs Plomp, Yvonne Evelina Thunell

Under normal viewing conditions, due to e.g. the motion of objects, the retinotopic representation of the environment constantly changes. Yet we perceive the world as stable and we easily keep track of moving objects, indicating the presence of non-retinot ...
