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.

Predicting Replicated Database Scalability from Standalone Database Profiling

Willy Zwaenepoel, Sameh Mohamed Elnikety, Emmanuel Cecchet

This paper develops analytical models to predict the throughput and the response time of a replicated database using measurements of the workload on a standalone database. These models allow workload scalability to be estimated before the replicated system ...

The dynamical response properties of neocortical neurons to temporally modulated noisy inputs in vitro

Michele Giugliano

Cortical neurons are often classified by current-frequency relationship. Such a static description is inadequate to interpret neuronal responses to time-varying stimuli. Theoretical studies suggested that single-cell dynamical response properties are neces ...

Novel Oxygen Selective Complexes for Optical Oxygen Sensing

Michael Graetzel, Mohammad Khaja Nazeeruddin

Novel optical sensing films for oxygen based on highly luminescent iridium (III) and ruthenium (II) complexes have been developed. These demonstrate excellent long-term photostability (several months) when incorporated into polystyrene membranes. The influ ...

Tashkent+: Memory-Aware Load Balancing and Update Filtering in Replicated Databases

Willy Zwaenepoel, Sameh Mohamed Elnikety

BEST PAPER AWARDWe present a memory-aware load balancing (MALB) technique to dispatch transactions to replicas in a replicated database. Our MALB algorithm exploits knowledge of the working sets of transactions to ...

High speed dynamics of photonic crystal nanocavity laser

Hatice Altug

We demonstrated high-speed photonic crystal nanocavity lasers with response time as short as similar to 2ps and direct modulation speeds exceeding 100GHz. Such high-speed characteristics are enabled by the use of cavity quantum electrodynamics effects such ...

Conflict-Aware Scheduling for Dynamic Content Applications

Willy Zwaenepoel

We present a new lazy replication technique, suitable for scaling the back-end database of a dynamic content site using a cluster of commodity computers. Our technique, called conflict-aware scheduling, provides both throughput scaling and 1-copy serializa ...

Dynamical plasma response during driven magnetic reconnection

Ambrogio Fasoli

Direct measurements of a collisionless current channel during driven magnetic reconnection are obtained for the first time on the Versatile Toroidal Facility. The size of the diffusion region is found to scale with the electron drift orbit width, independe ...

Replication et Durabilité dans les systèmes répartis

Distributed dats bases and data replication are recognised today as an efficient way to increase availability and fiability in data bases. The problem of mutual co-herence of copies is however introduced. Updating data is to be done on all copies. The noti ...

Exploiting Atomic Broadcast in Replicated Databases

Rachid Guerraoui, André Schiper, Fernando Pedone

Exploiting Atomic Broadcast in Replicated Databases F.Pedone, R.Guerraoui and A.Schiper Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distribute ...
