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.

A Rate-based Prefiltering Approach to BLAST Acceleration

Dionysios Pnevmatikatos, Sotiria Fytraki

DNA sequence comparison and database search have evolved in the last years as a field of strong competition between several reconfigurable hardware computing groups. In this paper we present a BLAST preprocessor that efficiently marks the parts of the data ...

Semantics of OCL specified with QVT

Slavisa Markovic

The Object Constraint Language (OCL) has been for many years formalized both in its syntax and semantics in the language standard. While the official definition of OCL's syntax is already widely accepted and strictly supported by most OCL tools, there is n ...

A Web Survey for Facial Expressions Evaluation

Michel Bierlaire, Jean-Philippe Thiran, Matteo Sorci, Gianluca Antonini

In the recent years, researchers have investigated several methods of facial expression analysis. Their interest has been to apply their algorithms to sets of images labelled by a restrained number of experts. In order to deal with the generalizability of ...

Deferred-update database replication

Rodrigo Malta Schmidt

This thesis is about the design of high-performance fault-tolerant computer systems. More specifically, it focuses on how to develop database systems that behave correctly and with good performance even in the event of failures. Both performance and depend ...

An Analysis of Database System Performance on Chip Multiprocessors

Anastasia Ailamaki, Babak Falsafi, Frederick Ryan Johnson, Ippokratis Pandis

Prior research shows that database system performance is dominated by off-chip data stalls, resulting in a concerted effort to bring data into on-chip caches. At the same time, high levels of integration have enabled the advent of chip multiprocessors and ...

Extending OWL with Explicit Dependency

Jean Paul Calbimonte Perez

Functional Dependency has been extensively studied in database theory. It provides an elegant formalism for specifying key constraints and is the basis for normalization theory used in Relational database design. Given its known axiomatization through logi ...

Design tools for large networks

Bryn Andrew Martin

The Atlas TDAQ network consists of four separate networks which together total over 8000 ports at 1 Gbit/s, 60 ports at 10 Gbit/s, 200 Ethernet switches at the edge of the network, 6 multi-blade chassis switches at the core and over 20 km of copper and fib ...

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 ...
