In this paper, we present a definition of fuzzy multivalued dependencies in fuzzy databases with linguistic data based on similarity relation which is built by partitioning the domain of attribute values corresponding to an appropriate hedge algebra. Some properties of fuzzy multivalued dependencies are studied. Finally, the set of inference rules is shown to be sound and complete for a relation scheme class when it satisfies some specified...

This paper presents a method for automatic structural analysis of digital videos to generate the table of content and the index table of the given videos.These tables allow storing videos by a hierarchy of video, cluster of shots, shots, key-frames of shots, cluster of regions. Then a method for retrieving videos by using the input data as visual feature and semantic concepts is represented.

In network designing phase, one of QoS problems is designing survivable networks to assure that services are not disrupted when a failure happens. On an ATM, MPLS, GMPLS based-on network techonologies, there are many approaches for designing survivable networks. This paper introduces a genetic algorithm for topological design of survivable networks by a repetitively-restorable method.

When computer virus wide spreads in the world nowadays, anti-virus needs to improve their identifying methods to enhance the performance. In this paper, we introduce a new method to diagnose computer virus. First, we analyse the characteristics of viral data type to define virus classes through object-oriented methods. Second, we study the machine learnning mechanism for each virus class. Finally, we apply these learning forms to a data...
