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.
Complex networks exist for a number of purposes. The neural, metabolic and food networks ensure our survival, while the social, economic, transportation and communication networks allow us to prosper. Independently of the purposes and particularities of th ...
We investigate two important problems in media delivery via active network agents. First, we consider streaming multiple video assets over a shared backbone network through an intermediate proxy-server to a set of receiving clients. The proxy is located at ...
In this paper, we formulate a delay-power control (DPC) scheme for wireless networking, which efficiently balances delay against transmitter power on each wireless link. The DPC scheme is scalable, as each link autonomously updates its power based on the i ...
Ramp metering is beneficial for freeway throughput, but the ramp queues that are created should be prevented from extending to adjacent street junctions. A recently proposed ramp queue controller is investigated in conjunction with the local ramp-metering ...
We consider a transmission of a delay-sensitive data stream (e. g., a video call) from a single source to a single destination. The reliability of this transmission may suffer from bursty packet losses - the predominant type of failures in today's Internet ...
Many atomic broadcast algorithms have been published in the last 20 years. Token-based algorithms represent a large class of these algorithms. Interestingly, all the token-based atomic broadcast algorithms rely on a group membership service and none of the ...
When users submit new queries to a distributed stream processing system (DSPS), a query planner must allocate physical resources, such as CPU cores, memory and network bandwidth, from a set of hosts to queries. Allocation decisions must provide the correct ...
We evaluate, by measurements on a real testbed, the performance of networking services required for spot applications. We call a “spot application” an application for smartphones (such as “Ad-hoc Flash Sales”) that disseminates information in a local neigh ...
Achieving the main memory (DRAM) required bandwidth at ac- ceptable power levels for current and future applications is a ma- jor challenge for System-on-Chip designers for mobile platforms. Three dimensional (3D) integration and 3D stacked DRAM mem- ories ...
Hall-effect devices make up by far the largest part of all magnetic sensors on the market today. The main reason is compatibility of Hall devices with modern semiconductor technology. In particular, integrated Hall sensor micro-systems fabricated in low-co ...
