In order to use files in database federations, we propose to migrate file data into a relational database.
Integrating the database in a federation is then well-understood. This procedure has the adv...
Fault-Tolerant Control of a Distributed Database System
Fault-Tolerant Control Distributed Database System
2009/9/7
Optimal state information-based control policy for a distributed database system subject to server failures is considered. Fault-tolerance is made possible by the partitioned architecture of the syste...
A Content-Based Fuzzy Image Database Based on The Fuzzy ARTMAP Architecture
Fuzzy Image Database Fuzzy ARTMAP Architecture
2009/7/28
A major design issue in content-based image retrieval system is the selection of the feature set. This study attacks the problem of finding a discriminative feature for each class, which is optimal in...

AUTOMATIC MODELING OF THE LINGUISTIC VALUES FOR DATABASE FUZZY QUERYING
Database Flexible Query Linguistic Values Knowledge Acquisition
2010/1/11
In order to evaluate vague queries, each linguistic term is considered according to its fuzzy model. Usually, the linguistic terms are defined as fuzzy sets, during a classical knowledge acquisition o...
