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 abstractForecasting Air Temperatures Using Time Series Models and Neural-based AlgorithmsMahmoud M. Smadi, Farouq S. MjalliRecently, neural network models have been popular and found useful for forecasting a wide variety of time series data in many disciplines. This is due to their favorable modeling properties of simplicity, fault and noise tolerance and their capability to adapt to process changes. Nevertheless, applications in climatology have been less widespread than other disciplines such as economics. In this … …Journal of Mathematics and Statistics, Vol. 3, Issue 2 · 30 Jun 2007 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractFault-tolerant Distributed Systems with Diagnostics AlgorithmsOleg Viktorov, Afif MghawishTo provide consistent actions in distributed systems with faulty nodes the Byzantine agreement protocol (algorithm) is widely used. In case of using message exchange scheme without authentication the Byzantine agreement algorithm leads to agreement if the number of nodes doesn’t exceed 1/3 of the total number. The proposed algorithms based on diagnostics procedures are used to reach an agreement in … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 4,840 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFault Detection of Computer Communication Networks Using an Expert SystemIbrahiem M.M. El Emary, Adanan I. Al RabiaThe main objective of this study was to build an expert system for assisting the network administrator in his work of management and administration of the computer communication network. Theory of operation of the proposed expert system depends on using a time series model capable of forecasting the various performance parameters as: delay, utilization and collision frequency. When the expert … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,125 accessesView PDFCite
