Research ArticleOpen accessIn the abstractFactors Affecting Agricultural Land Fragmentation in Iran: A Case Study of Ramjerd Sub District in Fars ProvinceKhalil Kalantari, Gholamhossein AbdollahzadehThe objective of this study was to examine the factors influencing fragmentation of landholdings commonly regarded as a major obstacle to agricultural development in Iran. A sample of farmers was selected and household and village-level data from 12 villages of Ramjerd sub district in Fars province were used to test these factors empirically. Required data were collected by questionnaire from … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,407 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome P-RAM Algorithms for Sparse Linear SystemsRakesh Kumar Katare, N.S. ChaudhariPRAM algorithms for Symmetric Gaussian elimination is presented. We showed actual testing operations that will be performed during Symmetric Gaussian elimination, which caused symbolic factorization to occur for sparse linear systems. The array pattern of processing elements (PE) in row major order for the specialized sparse matrix in formulated. We showed that the access function in2+jn+k contains topological properties. We … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 6,971 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 abstractOn The Integration of Decision Diagrams in High Order Logic Based Theorem Provers: a SurveySa'ed Abed, Otmane Ait Mohamed, Ghiath Al SammaneThis survey discuss approaches that integrate Decision Diagrams inside High Order Logic based Theorem provers. The approaches can be divided in two kinds, one is based on building a translation between model checker and theorem prover, the second is based on embedding the model checker algorithms inside the theorem prover. A comparison between both is discussed in detail. The paper … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,980 accessesView PDFCite
Research ArticleOpen accessIn the abstractMapping UML Component Specifications to JEE ImplementationsJyhjong LinComponent-based Software Engineering (CbSE) has become a well-accepted approach for developing complex software systems due to its significant advantages on composition and reuse. In practice, however, its use still requires the conjunction of a component specification method that describes how system requirements are satisfied in terms of software components. Such a component specification is then implemented in a variety of … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,478 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Calibration of Frequency Compensation System in Computer-Controlled Patch-Clamp AmplifierJun Xiong, Gang Hu, Anlian QuComputer-controlled patch-clamp amplifier is a digitally controlled analog device used to record the cellular ion channel currents in electrophysiology research. The inherent bandwidth and performance of the headstage is limited by the stray capacitance and distributed capacitance across the feedback resistors. In order to effectively improve the performance of the headstage, the paper advanced a simplified automatic calibration method of … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,814 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison of Different Image Sizes for Recognizing Unconstrained Handwritten Tamil Characters using SVMN. Shanthi, K. DuraiswamyThis study describes a system for recognizing offline handwritten Tamil characters using Support Vector Machine (SVM). Data samples are collected from different writers on A4 sized documents. They are scanned using a flat bed scanner at a resolution of 300 dpi and stored as grey scale images. Various preprocessing operations are performed on the digitized image to enhance the quality … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 7,008 accessesView PDFCite
Research ArticleOpen accessIn the abstractFoundry Wastes Reuse and Recycling in Concrete ProductionSilvia Fiore, Maria Chiara ZanettiThe industrial process of a cast iron foundry plant located in the North of Italy was analyzed in order to determine the amount and kind of produced wastes. The main fractions are core and moulding sands, muds and powders from dust abatement plants, furnace and ladle slags, and exhaust lime, making about 750-800 t/d of residues for a production of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,952 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmobilization of Lipase from Candida Rugosa on Palm-Based Polyurethane Foam as a Support MaterialRoila Awang, Mohd Rafaei Ghazuli, Mahiran BasriLipase from Candida rugosa was immobilized onto palm-based polyurethane foam (PU), which the polymer was pre-soaked in co-immobilized agent. The activities of PU-immobilized lipase were tested by the esterification reaction of oleic acid and oleyl alcohol in hexane. The PU-immobilized lipase was then characterized in term of its thermal, operational and storage stability. The optimum temperature for native and PU-immobilized … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,478 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulticultural Upper Secondary School Life in Denmark: Identifications, Solidarity and CitizenshipYvonne MørckEducation has played an important role in the development of the Nordic welfare states. As in other European countries, present day Denmark wrestles with the problem of finding ways to handle the increased diversity of its population in terms of, for instance, ethnicity, religion and language. Hence, negotiations and contestations about how to operationalize different forms of multiculturalism on all … …Journal of Social Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 8,037 accessesView PDFCite
