Research ArticleOpen accessIn the abstractEDGE PRESERVED IMAGE COMPRESSION USING EXTENDED SHEARLET TRANSFORMS. Thayammal, D. SelvathiThe motivation of the proposed compression method is to reduce the bit rate for image transmission or memory requirement for image storage while maintaining image quality. The edges are one of the prominent features in an image and they are essential for maintaining image quality. JPEG compression standards like JPEG98 and JPEG2000 produce visual artifacts in reconstructed image at low … …Journal of Computer Science, Vol. 11, Issue 1 · 15 Sep 2014 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractINTRUSION DETECTION IN MOBILE AD HOC NETWORK USING SECURE ROUTING FOR ATTACKER IDENTIFICATION PROTOCOLS. Gopalakrishnan, P. GaneshkumarIn past few decades, the migration of communication takes place from wired networks to wireless networks because of its mobility and scalability and Mobile Ad hoc Network (MANET) is a unique and significant application in recent years which does not necessitates any pre-existing network infrastructure.

Research ArticleOpen accessIn the abstractPROBABLE CREUTZFELDT JAKOB DISEASE: CASE REPORTYanes Brum Bello, Alexandre Cossenza Pettezzoni De Almeida, Daniela Mendonca Sueth et al.Prion diseases are associated with the accumulation of an abnormal isoformof cellular prion protein (PrPSc), which is the principal constituent of prions. Prions replicate in lymphoreticular tissues before neuroinvasion, suggesting that lymphoreticular biopsy samples may allow early diagnosis by detection of PrPSc. Creutzfeldt-Jakob Disease (CJD) is the most frequent prion disease in humans. Clinical diagnosis of sporadic (CJD) is based … …Current Research in Medicine, Vol. 5, Issue 1 · 14 Mar 2014 · 8,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Curcumin Based Ophthalmic FormulationD. Anjana, K. Anitha Nair, N. Somashekara et al.Problem statement: Ophthalmic drug delivery system has been a major challenge due to the distinctive and unique anatomy of the eye. The use of phytochemicals for the application in ocular disease has not been investigated much, due to poor pharmacokinetics of phytochemical and hence poor therapeutic efficacy. Approach: Curcumin is one such phytochemical known for its medicinal properties, but its … …American Journal of Infectious Diseases, Vol. 8, Issue 1 · 24 Feb 2012 · 15,401 accessesView PDFCite

Research ArticleOpen accessIn the abstractImpact of Malicious Nodes under Different Route Refresh Intervals in Ad Hoc NetworkP. Suganthi, A. TamilarasiProblem statement: Ad hoc networks are formed dynamically by group of mobile devices co operating with each other. Intermediate nodes between source and destination act as routers so that source node can communicate with the destination node even if it is out radio range and thus eliminating the necessity of infrastructure. Co operation of nodes is a very important feature … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 3 Nov 2011 · 7,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractConsistent and Proficient Algorithm for Data Gathering in Wireless Sensor NetworksP. Balamurugan, K. DuraiswamyProblem statement: A wireless sensor network is usually deployed in a harsh geographical area to gather data that can be delivered to the remotely located base station. Sensor nodes have irreplaceable energy source, limited computational capability and limited memory. It is a challenge to maximize the use of energy of these sensor nodes to extend the network lifetime. Approach: This … …Journal of Computer Science, Vol. 7, Issue 9 · 25 Jul 2011 · 6,732 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Algorithm for Localization in Vehicular Ad-Hoc NetworksHajar Barani, Mahmoud FathyPositioning a node in Vehicular Ad-Hoc networks is one of the most interested research areas in recent years. In many Ad-Hoc networks such as Vehicular Ad-Hoc networks in which the nodes are considered as vehicles, move very fast in streets and highways. So, to have a safe and fast transport system, any vehicle should know where a traffic problem such … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,363 accessesView PDFCite
Research ArticleOpen accessIn the abstractStandardization of Metal-Based Herbal MedicinesArun Sudha, V. S. Murty, T. S. ChandraProblem statement: Standardization of herbal drugs is a burning topic in herbal drug industry today. Standardization is difficult because they are usually mixtures of many constituents and the active principle in most cases is unknown. However it is possible to generate a physico-chemical fingerprint for the standardization of these drugs with reference to authentic drugs, for monitoring variation between preparations … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,904 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Effective Location-Based Power Conservation Scheme for Mobile Ad Hoc NetworksKhalid Kaabneh, Azmi Halasa, Hussein Al-BahadiliProblem statement: One of the major issues in current reactive routing protocols for Mobile Ad Hoc Networks (MANETs) is the high bandwidth and power consumptions during the routing process.
