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.

Color Encodings for Image Databases

Sabine Süsstrunk

There are a number of color encoding standards that have lately been developed ant are being proposed to the imaging community for different encoding steps in the color imaging workflow, optimized for different purposes. In this paper, their applicability ...

Speculative sequential consistency with little custom storage

Babak Falsafi

This paper proposes SC++lite, a sequentially consistent system that relaxes memory order speculatively to bridge the performance gap among memory consistency models. Prior proposals to speculatively relax memory order require large custom on-chip storage t ...

Group communications and database replication

Matthias Wiesmann

Databases are an important part of today's IT infrastructure: both companies and state institutions rely on database systems to store most of their important data. As we are more and more dependent on database systems, securing this key facility is now a p ...

Deconstructing Paxos

Rachid Guerraoui, Partha Dutta, Romain Boichat

The Paxos part-time parliament protocol of Lamport provides a non trivial but very practical way to implement fault-tolerant deterministic services over a distributed message passing system. This paper deconstructs Paxos and modularly reconstructs more res ...

Action-Oriented Exception Handling in Cooperative and Competitive Object-Oriented Systems

Jörg Kienzle

The chief aim of this survey is to discuss exception handling models which have been developed for concurrent object systems. In conducting this discussion we rely on the following fundamental principles: exception handling should be associated with struct ...

Sharing attractions on the Net with VPark

Daniel Thalmann, Joaquim Esmerado

We present a networked virtual environment (NVE) system and an attraction building system based on Windows NT that enables users to introduce their own scenario-based applications into a shared virtual environment. Our goal was to develop and integrate sev ...

Primary-backup replication: From a time-free protocol to a time-based implementation

André Schiper

Fault-tolerant control systems can be built by replicating critical components. However, replication raises the issue of inconsistency. Multiple protocols for ensuring consistency have been described in the literature. PADRE (Protocol for Asymmetric Duplex ...

Optimal location of multi-type FACTS devices in a power system by means of genetic algorithms

Stéphane Gerbex

This paper presents a genetic algorithm to seek the optimal location of multi-type FACTS devices in a power system. The optimizations are performed on three parameters: the location of the devices, their types and their values. The system loadability is ap ...
