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.

Labelling Game for Twitter Streams

Valérian Hanser

The main goal of this project is to build a mean and to populate a database with correct information regarding some decided pairings. This database will then be compared to the results of algorithms that process the same pairings, which provides a way to a ...

Discrete and Rhythmic Motor Primitives for the Control of Humanoid Robots

Sarah Dégallier Rochat

Controlling robots with multiple degrees of freedom (DOFs) is still an open and challenging issue, notably because planning complex, multidimensional trajectories in time-varying environments is a laborious and costly process. In this dissertation, we prop ...

Feedback control of ECRH polarization on LHD

Olivier Sauter, Timothy Goodman, Federico Alberto Alfredo Felici

The polarization of ECRH waves, set by the orientation of a pair of corrugated mirror polarizers in the transmission line, determines the degree of coupling to O- and X-modes in the plasma and has an important effect on the first-pass absorption. Existing ...

Neighbor discovery with reception status feedback to transmitters

Ramin Khalili

Neighbor discovery is essential for the process of self-organization of a wireless network, where almost all routing and medium access protocols need knowledge of one-hop neighbors. In this paper we study the problem of neighbor discovery in a static and s ...

Positive feedback in the transition from sexual reproduction to parthenogenesis

Séverine Vuilleumier Varisco

Understanding how new phenotypes evolve is challenging because intermediate stages in transitions from ancestral to derived phenotypes often remain elusive. Here we describe and evaluate a new mechanism facilitating the transition from sexual reproduction ...

Inner Control of Modular Multilevel Converters - An Approach using Open-loop Estimation of Stored Energy

Michail Vasiladiotis, Daniel Siemaszko

The inner control of a Modular Multilevel Converter (M2C) must be designed so that the submodule capacitor voltages are equalized and stable independent of the loading conditions. It has been shown that a submodule selection mechanism, included in the modu ...

CPG-based prostheses control

Marc Louis

In this thesis we describe a strategy to control robotic knees and ankles. A dynamical system is used to generate a position trajectory to control a servo motor replacing the missing joint. The dynamical system consists in a pool of coupled oscillators mod ...

Wireless Voltage Regulation for Passive Transponders Using an IF to Communicate

Catherine Dehollain, Michel Declercq, Nicolas Pillin

This paper presents a novel architecture for wireless communication systems made up of a base station and a remotely powered transponder. The architecture enables the base station to perform wireless voltage regulation (WVR) of the rectifier's output volta ...

Tunable optofluidic dye laser with novel cavity

Demetri Psaltis, Andreas Vasdekis, Wuzhou Song

We present a pressured mediated tunable optofluidic dye laser with novel cavity. The dye laser chip was fabricated with Polydimethylsiloxane (PDMS) via replica molding and has none nano-features. It comprises a liquid waveguide and micro-scale air-gap cham ...

Meander dynamics: A nonlinear model without curvature restrictions for flow in open-channel bends

Koen Blanckaert

Despite the rapid evolution of computational power, simulation of meander dynamics by means of reduced and computationally less expensive models remains practically relevant for investigation of large-scale and long-term processes, probabilistic prediction ...
