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.

Ultra low power NEMFET based logic

Mihai Adrian Ionescu, Antonios Bazigos, Surya Shankar Dan

In this paper, we introduce a Nano-Electro-Mechanical Field Effect Transistor (NEMFET) based logic family tailored to the implementation of low speed and ultra low energy functional units and processors. Basic Boolean gates implemented with NEMFETs only ar ...

Device-to-Device Assisted Video Transmission

Laura Toni, Wenwen Zhou

To increase spectrum efficiency, researchers envi- sion a device-to-device (D2D) communication system in which a closely located mobile device pair may share the same spectrum with a cellular user. By opportunistically choosing the frequency, the D2D pair ...

GPUfs: Integrating a File System with GPUs

Bryan Alexander Ford

As GPU hardware becomes increasingly general-purpose, it is quickly outgrowing the traditional, constrained GPU-as-coprocessor programming model. To make GPUs easier to program and improve their integration with operating systems, we propose making the hos ...

Scale-Out Processors

Pejman Lotfi Kamran

Global-scale online services, such as Google’s Web search and Facebook’s social networking, run in large-scale datacenters. Due to their massive scale, these services are designed to scale out (or distribute) their respective loads and datasets across thou ...

Models and Algorithms for Ultra-Wideband Localization in Single- and Multi-Robot Systems

Amanda Stella Markowska Prorok

Location is a piece of information that empowers almost any type of application. In contrast to the outdoors, where global navigation satellite systems provide geo-spatial positioning, there are still millions of square meters of indoor space that are unac ...

Progress Towards a Miniaturized Electrospray Thruster for Propulsion of Small Spacecraft

Herbert Shea, Caglar Ataman, Simon Dandavino, Subha Chakraborty

Miniaturized electrical thrusters based on electrospray (or colloid) emitters could rev- olutionize the spacecraft industry by providing efficient propulsion capabilities to micro and nano satellites (1-100 kg). We report on our recent advances in the deve ...
