Research ArticleOpen accessIn the author namesHandling 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 PDFCite
Research ArticleOpen accessIn the author namesModeling of Nitric Oxide Formation in Single Cylinder Direct Injection Diesel Engine Using Diesel-Water EmulsionK. Kannan, M. UdayakumarProblem statement: Water injection into the combustion chamber of diesel engine found to be one of best method for in-cylinder control of NOx formation. Approach: The combustion of water-diesel emulsion in diesel engine was simulated using a computer program to estimate the heat release rate, cylinder pressure, brake thermal efficiency, brake specific fuel consumption and NO formation. Results: The numerical … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,268 accessesView PDFCite
Research ArticleOpen accessIn the author namesAssessment of Site Specific Mutational Effect on Transcription Initiation at Escherichia coli PromoterS. Kannan, M. Krishnan, S. Sundarraj et al.Problem statement: It is widely accepted thought that the weak promoters control the RNA synthesis and play regulatory role in complex genetic networks in bacterial system. An experiment had been designed to address whether mutations in the -16/-17 region affect the rate of transcription at an activator-independent promoter in E. coli or not? Approach: The aim of this study was … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 7,555 accessesView PDFCite
Research ArticleOpen accessIn the author namesThree Dimensional Multidirectional Geographical IP Traceback: Direction Ratio Sampling AlgorithmA. Rajiv Kannan, K. Duraiswamy, K. SangeethaProblem statement: An important and challenging problem is that of tracing DOS/DDOS attack source. IP traceback is the process of identifying the actual source(s) of attack packets, So that the attackers can be held accountable as also in mitigating them, either by isolating the attack sources or by filtering packets for away from the victim. Several IP traceback schemes have … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,233 accessesView PDFCite
Research ArticleOpen accessIn the author namesReliability of Axially Loaded Fiber-Reinforced-Polymer Confined Reinforced Concrete Circular ColumnsVenkatarman Nagaradjane, Pulipaka Narasimharao Raghunath, Kannan SugunaMonte-Carlo simulation based procedure was applied for assessing the reliability of Fiber Reinforced Polymer (FRP) confined reinforced concrete columns. Assessment of reliability provides a quantitative measure of effectiveness of repair. Problem Statement: The procedure presented in the paper could be used for assessing the reliability of reinforced concrete columns before and after the application of FRP wrap, thus helping to … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2009 · 7,974 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Improved Handwritten Tamil Character Recognition System using Octal GraphR. J. Kannan, R. PrabhakarProblem Statement: Handwriting recognition has attracted voluminous research in recent times. The segmentation and recognition of the characters from handwritten scripts incorporates considerable overhead. Almost all the existing handwritten character recognition techniques use neural network approach, which requires lot of preprocessing and hence accomplishing these problems using neural network is a tedious task. Approach: In this study we propose a … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,405 accessesView PDFCite
Research ArticleOpen accessIn the author namesEnhancement of Search Results Using Dynamic Document Seed Reranking AlgorithmAngelina Geetha, A. KannanWe proposed an algorithm to improve the precision of top retrieved documents by re-ordering the retrieved documents in the initial retrieval. To re-order the documents, we first automatically extract key terms and key phrases from top N retrieved documents and generate a document index for each document. Using the standard similarity metrics, a document similarity matrix is generated for these … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,745 accessesView PDFCite
Research ArticleOpen accessIn the author namesLow Power Hardware Implementation of High Speed FFT CoreM. Kannan, S. K. SrivatsaApplications based on Fast Fourier Transform (FFT) such as signal and image processing require high computational power. This paper proposes the implementation of radix-4 based parallel-pipelined Fast Fourier Transform processor which incorporates a low power commutator, butter-fly with multiplier-less architecture. The proposed parallel pipelined architectures have the advantages of high throughput and low power consumption. The multiplier-less architecture uses shift … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 7,227 accessesView PDFCite
Research ArticleOpen accessIn the author namesHeparin-PF4 Antibodies in Heparin Induced Thrombocytopenia: Its Relationship with FcgRIIa PolymorphismMeganathan Kannan, Firdos Ahmad, Sarfraz Ahmad et al.We did the pilot study, in an attempt to determine the prevalence of HIT in Indians and determine its relationship, if any, to FcγRIIa polymorphism, the occurrence of heparin-induced thrombocytopenia (HIT) was investigated in 33 Indian patients undergoing cardiovascular surgery (CVS) who received unfractionated heparin (UFH). Platelet counts were performed prior to the initiation of UFH therapy and 5-16 days, … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,432 accessesView PDFCite
