Research ArticleOpen accessIn the abstractSolid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanWaste management became focus of attention of many researchers and scientists in the last half century due to its vital importance. Waste management covered waste source reduction in general, by recycling, reusing, composting, incineration with or without energy recovery, fuel production and land filling. A common approach of waste management models were for specific problems with a limited scope (like … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Factors Impinges Computer Usage in EducationNaresh Kumar, Raduan Che Rose, Jeffrey Lawrence D’SilvaThe growing body of literature associated with educational computer use had examined numerous variables and interrelationships in order to gain a better understanding of computer beliefs and use of computers within education. Teachers' computer acceptance is an important factor to the successful use of computers in education. Thus it is significant to draw attention to the factors affecting teachers' computer … …Journal of Social Sciences, Vol. 4, Issue 2 · 30 Jun 2008 · 8,226 accessesView PDFCite

Research ArticleOpen accessIn the abstractFeature Analysis of Ontology Mediation ToolsRavi Lourdusamy, Gopinath GanapathyOntology mediation is enabled through interoperability of semantic data sources. It helps data sharing between heterogeneous knowledgebase and reuse by semantic applications. Ontology mediation includes operations such as, mapping, alignment, matching, merging and integration. After briefly describing these operations, this study selectively discusses set of methods, tools and data integration systems. It provides the researchers a comprehensive understanding of methods … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,657 accessesView PDFCite
Research ArticleOpen accessIn the abstractGender Differences in the Usage and Attitudes toward the Internet among Student Teachers in a Public Malaysian UniversityWong Su Luan, Ng Siew Fung, Hanafi AtanThe problems of gender disparity in the usage and attitude towards the Internet have received considerable interest among researchers. Most findings have revealed that females are at a disadvantage compared to their male counterparts where Internet usage is concerned. They have unequal access, a low rate of usage and exhibit negative attitudes towards the Internet (Nachmias et al., 2000; Sherman … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,571 accessesView PDFCite
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 · 6,967 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 · 7,721 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 · 6,489 accessesView PDFCite
