Research ArticleOpen accessIn the abstractUsing IRS Products to Recover 7ETM+ Defective ImagesMobasheri Mohammad Reza, Sadeghi Naeini AliOn May 31st, 2003, Landsat 7 faced an anomaly in the Scan Line Corrector (SLC) normal operation. This malfunctioning of SLC caused the individual scan lines alternately overlap each other and consequently produce large gaps at the edges of the image. Regarding the unique specification of ETM+ sensor on board of Landsat-7 satellite such as its spectral bands in the … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 6,963 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Barbell Trajectory During The Snatch Lift Technique By Using Optimal Control TheoryShahram Lenjan Nejadian, Mostafa Rostami, Farzad TowhidkhahMathematical modeling and optimizing of snatch lift technique based on dynamic synthesis, is the aim of this study. The barbell trajectory is proposed as the performance index, evaluated experimentally by several researchers who have introduced some optimum trajectories according to the percentage of their owners' successes. Since none of the mechanical parameters were considered into the optimum trajectories, we develop … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach for Testing Stability of 1-D Recursive Digital Filters Based on Lagrange MultipliersK. R. Santhi, N. Gangatharan, M. PonnavaikkoDigital filters have found their way into many products from every day consumer items such as mobile phones to advanced maritime and military communications and avionics systems. Design of digital filters faces two fundamental problems, their stability and synthesis. Recursive filters have more stability problems than nonrecursive filters. Stability of a filter can be determined by the location of the … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,484 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Clustering Protocols in Mobile Ad hoc NetworksSharmila J. Francis, Elijah B. RajsinghNetwork clustering is an important technique widely used in efficient MANETs network management, hierarchical routing protocol design, network modeling, Quality of Service, etc. Recently many researchers are focusing on clustering which is one of the fundamental problems in mobile ad hoc networks. This article presents the descriptions of recently proposed clustering algorithms and is categorized into different approaches that support … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 6,947 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Spatial ARM (Spatial Association Rule Mining) for Geo-Decision Support SystemRanjana Vyas, Lokesh Kumar Sharma, U. S. TiwaryGeographical Decision Support System (Geo-DSS) is a demanding field, since enormous amount of spatial data have been collected in various applications, ranging form Remote Sensing to GIS, Computer Cartography, Environmental Assessment and Planning. Although some efforts were made to combine spatial mining with Spatial Decision Support System but mostly researchers for spatial database are using a popular data mining approach-Apriori … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractCustomized Privacy Preservation Using Unknowns to Stymie Unearthing Of Association RulesJ. Indumathi, G.V. UmaThe explosions of new data mining techniques has augmented privacy risks because now it is probable to powerfully coalesce and cross-examine massive data stores, accessible on the web, in the rummage around of earlier unidentified hidden patterns. Consecutively to make a overtly accessible system safe and sound, we must guarantee not only that private sensitive data have been trimmed out, … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 7,117 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeciding Whether There is Statistical Independence or Not?Ramzi NasserThe study investigated how students assess statistical independence (SI). A sample of 98 students was available to the researcher. One group was probed on their understanding of statistical independence, a second group was given a proficiency test and a third group was presented a proof for statistical Independence. Interview data from the first two groups exposed student misconception on their … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmploying New Mathematical Models and Equations to Evaluate Risk-Benefit Criteria of Clinical TherapeuticsDa Yong Lu, Ting Ren Lu, Jian DingCurrent preclinical and clinical evaluation of a drugs or therapy is at first to find out a maximum toxicity tolerance, which is overall fixed. The potential therapeutic dosage will be ranged just lower or within the periphery of these maximum tolerant data. A hidden acceptance among general researchers lies as the toxicity concentration of a drug is always the same … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 30 Jun 2007 · 6,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Quantitative Assessment Model For Usability EngineeringHaidar S. Jabbar, T. V. Gopal, Sattar J. AboudMany different quantitative assessment models have been proposed to measure and report the usability of a general software product for various business and design purposes. However, there are several problems coupled with existing models that consequently bias and affect the process and results of the usability assessment. Moreover, they do not aid their usage by analysts who are not experienced … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 6,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuery Pattern-based Relational Data to XML Data Translation AlgorithmJinhyung Kim, Dongwon Jeong, Doo-Kwon BaikThis paper proposes a new query pattern-based relational schema-to-XML schema translation (QP-T) algorithm to resolve implicit referential integrity issue. Various translation methods have been introduced on structural aspects and/or semantic aspects. However, most of conventional methods consider only explicit referential integrities specified by relational schema. It causes several problems such as incorrect transformation, abnormal relational model transition and so on. … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,188 accessesView PDFCite
