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.

High-beta, steady-state hybrid scenario on DIII-D

Holger Reimerdes

The potential of the hybrid scenario (first developed as an advanced inductive scenario for high fluence) as a regime for high-beta, steady-state plasmas is demonstrated on the DIII-D tokamak. These experiments show that the beneficial characteristics of h ...

MOOLs for MOOCs: A first edX scalable implementation

Denis Gillet, Christophe Salzmann, Yves Henri Philippe Piguet

Deploying remote laboratories at a large scale is the next challenge in remote experimentation. It is referred as Massive Open Online Labs (MOOLs). Being able to sustain a massive number of users accessing a specific resource concurrently is a complex task ...

Libra: Software-Controlled Cell Bit-Density to Balance Wear in NAND Flash

Paolo Ienne, David Novo Bruna, Xavier Jimenez

Hybrid flash storages combine a small Single-Level Cell (SLC) partition with a large Multilevel Cell (MLC) partition. Compared to MLC-only solutions, the SLC partition exploits fast and short local write updates, while the MLC part brings large capacity. O ...

Plug-and-play state estimation and application to distributed output-feedback model predictive control

Giancarlo Ferrari Trecate, Marcello Farina

In this paper we propose a novel distributed state estimator for large-scale linear systems composed by subsystems interacting through state variables. The distributed state estimator has the following features: (i) local state estimators, each dedicated t ...

Assessment of the ITER EC Upper Launcher Performance

Olivier Sauter, Timothy Goodman, Emanuele Poli

The 24 MW ITER Electron Cyclotron (EC) Heating and Current Drive (H&CD) system, operating at 170 GHz, consists of one Equatorial (EL) and four Upper Launchers (UL). The main task of the UL will be the control of Magneto-Hydrodynamic (MHD) activity such as ...

A (Nearly) Free Lunch

Xavier Jimenez

NAND flash is a key storage technology in modern computing systems. Without it, many devices would probably not exist today or would at least not benefit from as many features. The very large success of this technology motivated massive efforts to scale it ...
