Research ArticleOpen accessIn the abstractPreserving Data Consistency through Neighbor Replication on Grid DaemonA. Noraziah, M. Mat Deris, N.A. Ahmed et al.In modern distributed systems, replication receives particular attention for providing high data availability, fault tolerance and enhance the performance of the system. It is an important mechanism because it enables organizations to provide users with access to current data where and when they need it. However, this way of data organization introduces low data consistency and data coherency as more … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,883 accessesView PDFCite
Research ArticleOpen accessIn the abstractFormal Analysis of Fault-tolerant Algorithm in the Time-triggered ArchitectureAliouat Zibouda, Aliouat Makhlouf, Batouche ChawkiTime-Triggered architecture (TTA) provides a computing infrastructure for the design and implementation of dependable distributed systems. The core building block of the TTA is the communication protocol TTP/C. This protocol has been designed to provide no faulty nodes. TTP/C integrates a set of fault-tolerant services like: message transmissions, clocks synchronization and Group Membership Protocol (GMP). The GMP protocol ensures that … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,647 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnderstanding a Simple Arabic Stories Using Event CalculusMohamed Abd El-Salam, Ahmed Kamal Hussein, Aly Aly FahmyThis study investigates the use of event calculus for understanding stories written in Arabic natural language. System makes a representation for commonsense knowledge and story events and then performs a commonsense reasoning to infer the details events which are not explicitly described in the story; furthermore it manages changes in objects properties over time and handles the actions synchronizations problem. …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 6,639 accessesView PDFCite
