Research ArticleOpen accessIn the author namesSecurity in MANET’s by Using Detective Signature TechniquesGayathri A., P. NarayanasamyMobile Ad-hoc Network (MANET) is one among the fastest growing area in the field of research where security is a vital factor for protecting MANET against attacks, EAACK is an acknowledgement based IDS which is composed of three parts namely, ACK, S-ACK and MRA along with digital signature to provide security against attacks. Till now contemporary technique such as EAACK … …Journal of Computer Science, Vol. 11, Issue 3 · 21 Apr 2015 · 6,778 accessesView PDFCite
Research ArticleOpen accessIn the author namesAUTOMATIC TEXT EXTRACTION FROM COMPLEX COLORED IMAGES USING GAMMA CORRECTION METHODG. Gayathri Devi, C. P. SumathiThe aim of this study is to propose a new methodology for text region extraction and non text region removal from complex background colored images. This study presents a new approach based on Gamma correction by determining a gamma value for enhancing the foreground details in an image. The approach also uses gray level co-occurrence matrices, texture measures, threshold concepts. … …Journal of Computer Science, Vol. 10, Issue 4 · 24 Dec 2013 · 6,679 accessesView PDFCite
Research ArticleOpen accessIn the author namesA CONTEXT-BASED TECHNIQUE USING TAG-TREE FOR AN EFFECTIVE RETRIEVAL FROM A DIGITAL LITERATURE COLLECTIONMuthuraman Thangaraj, Vengatasubramanian GayathriThe increasing growth of information in online digital libraries causes an increasing need to develop techniques to retrieve. In the digital library, findability-finding the user required information is a hectic task than those of usability. The major issues in findability are (a) topic diffusion: results of a traditional keyword based search, often leads to multiple topic areas, some of which … …Journal of Computer Science, Vol. 9, Issue 11 · 5 Oct 2013 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the author namesPalmprint Recognition using Feature Level FusionR. Gayathri, P. RamamoorthyProblem statement: Palmprint based biometric method has gained high impact over the other biometric methods due to its ease of acquisition, reliability and high client acceptance. Multiple feature extraction from image gives higher accuracy of the authentication system. Approach: This study presents the palmprint based identification methodology which uses the Gabor wavelet entropy to extract multiple features existing on the … …Journal of Computer Science, Vol. 8, Issue 7 · 19 May 2012 · 6,982 accessesView PDFCite
Research ArticleOpen accessIn the author namesAutomatic Palmprint Identification based on High Order Zernike MomentR. Gayathri, P. RamamoorthyProblem statement: Hand geometry contains relatively invariant features of an individual. Palmprint recognition is an efficient biometric solution for authentication system. The existence of several hand-based authentication commercial systems indicates the effectiveness of this type of biometric. Approach: We proposed a palmprint verification system using high order Zernike moment that was robust to rotation, translation and occlusion. Zernike moment was … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 12 Mar 2012 · 7,193 accessesView PDFCite
Research ArticleOpen accessIn the author namesAutomatic Personal Identification Using Feature Similarity Index MatchingR. Gayathri, P. RamamoorthyProblem statement: Biometrics based personal identification is as an effective method for automatically recognizing, a person’s identity with high confidence. Palmprint is an essential biometric feature for use in access control and forensic applications. In this study, we present a multi feature extraction, based on edge detection scheme, applying Log Gabor filter to enhance image structures and suppress noise. Approach: … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 2 Mar 2012 · 6,715 accessesView PDFCite
Research ArticleOpen accessIn the author namesReconciling the Bio Safety Protocol and the WTO Regime: Problems, Perspectives and PossibilitiesP. G. Gayathri, Reshma R. KurupProblem statement: The issue of regulation of international trade in Genetically Modified Organisms (GMOs) evokes a very unique, passionate and emotional debate between environmentalists and businesses. At the conceptual level itself, like most other multilateral environmental agreements, the Cartagena Protocol appears to be incompatible with the WTO Rules. Approach: Further, since there is precious little scientific certainty on the actual … …American Journal of Economics and Business Administration, Vol. 1, Issue 3 · 30 Sep 2009 · 7,780 accessesView PDFCite
Research ArticleOpen accessIn the author namesUpgrading of Light Dewaxed Oil through Hydrofinishing and Additives Blending for Producing Automatic Transmission FluidGamal Abdel-Nasser Gohar, Mohamed Sherif El-Gayar, Abd El-Moneim Ibrahim et al.Light dewaxed oil was produced through dewaxing process of the light waxy distillate raffinate of crude oil from Western Desert of Egypt using methyl ethyl ketone/toluene mixed solvent. Hydrofinishing process was used to remove the non-hydrocarbon constituents and to improve the physicochemical properties of the produced oils such as color, viscosity index, inhibition responses, oxidation and thermal stability. The operating … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,976 accessesView PDFCite
