Research ArticleOpen accessIn the abstractEnhancing the Color Set Partitioning in Hierarchical Tree (SPIHT) Algorithm Using Correlation TheoryM. Santhi, R. S.D. Wahida BanuProblem statement: Efficient color image compression algorithm is essential for mass storage and the transmission of the image. The compression efficiency of the Set Partitioning in Hierarchical Tree (SPIHT) coding algorithm for color images is improved by using correlation theory. Approach: In this study the correlation between the color channels are used to propose the new algorithm. The correlation between … …Journal of Computer Science, Vol. 7, Issue 8 · 16 Jul 2011 · 6,622 accessesView PDFCite

Therefore, this study explored the management of multilingual data in multilingual system in order to be able to cater two or more different speakers of Internet users. Approach: The proposed method is divided into two ends: The front-end … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 7,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecure Group Key Management for Dynamic Sensor NetworksN. Suganthi, V. Sumathi, R S. MohanapriyhaProblem statement: Key management is an important cryptographic technique for providing security in a dynamic environment of sensor networks. To provide a secure communication among a group of sensor nodes keys should established in an efficient manner. We introduced an efficient and dynamic key management system for dynamic sensor networks. Approach: We pre deployed some of the keying materials in … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,749 accessesView PDFCite
Research ArticleOpen accessIn the abstractBio-Potential Signal Extraction from Multi-Channel Paper Recorded ChartsAli S.A. Al-MejradProblem Statement: Almost all of the modern biomedical equipments that record the biopotential actions have digital output but the paper chart records are a must. The volume of these records is significant and increasing rapidly. Keeping a bio-signal chart of a patient make it easy for quick assessment but still create problems in the essence of data storage, archiving , … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 7,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractTopological Decoupled Group Key Management for Cellular NetworksJorge Estudillo Ramirez, Saul Eduardo Pomares Hernandez, Gustavo Rodriguez Gomez, Jose Roberto Perez CruzProblem statement: The continuous increasing capacity of the cellular networks motivates the development of multiparty applications, such as interactive mobile TV and mobile social networks. For these environments, security group services are required. A practical way to provide security services is by using cryptographic methods. However, the key management needed for these methods, which considers a dynamic group membership, introduces … …Journal of Computer Science, Vol. 7, Issue 3 · 9 Mar 2011 · 6,870 accessesView PDFCite
Research ArticleOpen accessIn the abstractOligoglucans as Elicitors of an Enzymatic Antioxidant System in Zucchini Squash (Cucurbita pepo L.) Seedlings at Low TemperatureAbel Ceron-Garcia, Gustavo Adolfo Gonzalez-Aguilar, Irasema Vargas-Arispuro et al.Abstract: Problem statement: Non-controlled low temperatures affect physiological and biochemical processes leading to Reactive Oxygen Species (ROS) accumulation in plants, which normally are stabilized by the antioxidant system. Superoxide Dismutase (SOD), Ascorbate Peroxidase (APX) and Catalase (CAT) are the most important ROS-detoxification enzymes in stressed plants. Approach: The activity of these enzymes were examined in response to fungal Oligoglucans (OG) … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,308 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Disruption-Tolerant Model for Building a Mobile Application Using Web ServiceMaryati Mohd. Yusof, Mansor Omar, Zarina ShukurProblem statement: The emerging technology in broadband telecommunication and mobile devices has increased the use of mobile applications. However, the use of mobile application is affected with low bandwidth or disrupted broadband telecommunication due to building blockage or out of coverage area. Approach: We proposed a Disruption-Tolerant Mobile Application Model (DTMA) that enables remote data access and overcomes constraint due … …Journal of Computer Science, Vol. 6, Issue 12 · 1 Dec 2010 · 7,224 accessesView PDFCite
Research ArticleOpen accessIn the abstractControlling Label Size Increment of Efficient XML Encoding and Labeling Scheme in Dynamic XML UpdateMeghdad Mirabi, Hamidah Ibrahim, Ali Mamat et al.Problem statement: In order to facilitate XML query processing, labeling schemes are used to determine the structural relationships between XML nodes. However, labeling schemes have to reliable the existing nodes or recalculate the label values when a new node is inserted into the XML document during XML update process. EXEL as a labeling scheme is able to remove relabeling for … …Journal of Computer Science, Vol. 6, Issue 12 · 30 Nov 2010 · 7,421 accessesView PDFCite
