Research ArticleOpen accessAll words, across the recordA Novel Local Network Intrusion Detection System Based on Support Vector MachineMuamer N. Mohammad, Norrozila Sulaiman, Emad T. KhalafProblem statement: Past few years have witnessed a growing recognition of intelligent techniques for the construction of efficient and reliable Intrusion Detection Systems (IDS). Many methods and techniques were used for modeling the IDS, but some of them contribute little or not to resolve it. Approach: Intrusion detection system for local area network by using Support Vector Machines (SVM) was … …Journal of Computer Science, Vol. 7, Issue 10 · 6 Aug 2011 · 7,313 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHandling Web and Database Requests Using Fuzzy Rules for Anomaly Intrusion DetectionSelvamani Kadirvelu, Kannan ArputharajProblem statement: It is necessary to propose suitable detection and prevention mechanisms to provide security for the information contents used by the web application. Many prevention mechanisms which are currently available are not able to classify anomalous, random and normal request. This leads to the problem of false positives which is classifying a normal request as anomalous and denying access … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,305 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordTransient Stability Assessment of a Power System Using Probabilistic Neural NetworkNoor Izzri Abdul Wahab, Azah MohamedThis study presents transient stability assessment of electrical power system using Probabilistic Neural Network (PNN) and principle component analysis. Transient stability of a power system is first determined based on the generator relative rotor angles obtained from time domain simulation outputs. Simulations were carried out on the IEEE 9-bus test system considering three phase faults on the system. The data … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,027 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Novel Video Surveillance System Based on Multimedia Messaging ServiceS. Chandramathi, N. Chandra Sekhar, M. G. AdarshToday’s communication world ensures that anybody can communicate to anyone anywhere anytime across the globe. The new mobile communication systems include not only voice but also data and video messages. Natural way to communicate is to send and receive messages. Multimedia messaging are essential drivers for continuous growth in new services beyond voice. In this study, multimedia messaging services available … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,914 accessesView PDF Cite
