Classifying Materials in the Real World
Classifying materials from their appearance is challenging. Impressive results have been obtained under varying illumination and pose conditions. Still, the effect of scale variations and the possibility to generalize across different material samples are ...
IDIAP2007Cursive Character Challenge: a New Database for Machine Learning and Pattern Recognition
Cursive character recognition is a challenging task due to high variability and intrinsic ambiguity of cursive letters. This paper presents \emph{C-Cube} (Cursive Character Challenge), a new public-domain cursive character database. \emph{C-Cube} contains ...
2006Dependable Systems
Improving the dependability of computer systems is a critical and essential task. In this context, the paper surveys techniques that allow to achieve fault tolerance in distributed systems by replication. The main replication techniques are first explained ...
Springer Berlin Heidelberg2006Optimistic Algorithms for Partial Database Replication
Nicolas Schiper, Rodrigo Malta Schmidt, Fernando Pedone
In this paper, we study the problem of partial database replication. Numerous previous works have investigated database replication, however, most of them focus on full replication. We are here interested in genuine partial replication protocols, which req ...
2006A Primary-Backup Protocol for In-Memory Database Replication
Rodrigo Malta Schmidt, Fernando Pedone
The paper presents a primary-backup protocol to manage replicated in-memory database systems (IMDBs). The protocol exploits two features of IMDBs: coarse-grain concurrency control and deferred disk writes. Primary crashes are quickly detected by backups an ...

2006Database Replication Using Generalized Snapshot Isolation
Willy Zwaenepoel, Sameh Mohamed Elnikety, Fernando Pedone
Generalized snapshot isolation extends snapshot isolation as used in Oracle and other databases in a manner suitable for replicated databases. While (conventional) snapshot isolation requires that transactions observe the “latest” snapshot of the database, ...
2005Architectural Issues of JMS Compliant Group Communication
Nils Richard Ekwall, Arnas Kupsys
Group communication provides one-to-many communication primitives that simplify the development of highly available services. Despite advances in research and numerous prototypes, group communication stays confined to small niches. To facilitate the accept ...
