Research ArticleOpen accessData Replication Using Read-One-Write-All Monitoring Synchronization Transaction System in Distributed EnvironmentNoraziah Ahmad, Ahmed N. Abdalla, Roslina Mohd SidekNowadays, the demand of transmitted information over networks increase rapidly and the demand for steady bandwidth seems to be out of control. Particularly organizations need to provide updated data to users that might be geographically remote and handling a vast amount of requested data distributed in multiple sites. Problem statement: Replication in distributed environment has become increasingly popular due to … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Jul 2010 · 7,048 accessesView PDFCite
Research ArticleOpen accessIntrusion Preventing System using Intrusion Detection System Decision Tree Data MiningSyurahbil, Noraziah Ahmad, M. Fadly Zolkipli, Ahmed N. AbdallaProblem statement: To distinguish the activities of the network traffic that the intrusion and normal is very difficult and to need much time consuming. An analyst must review all the data that large and wide to find the sequence of intrusion on the network connection. Therefore, it needs a way that can detect network intrusion to reflect the current network … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,337 accessesView PDFCite
Research ArticleOpen accessWinner-Take-All Neural Network with Massively Optoelectronic InterconnectionsWissam H. Ali, Ahmed N. Abdalla, Wa'l H. AliThe increased interconnection density, bandwidth, nonlocality and fan-out-fan-in offered by optics over conventional electronic technologies make it a very attractive medium for a variety of application particularity in the field of communication system implementation for all types of computing engines is achieved.
