Research ArticleOpen accessIn the abstractImproving Email Response in an Email Management System Using Natural Language Processing Based Probabilistic MethodsAbdulkareem Al-AlwaniEmail based communication over the course of globalization in recent years has transformed into an all-encompassing form of interaction and requires automatic processes to control email correspondence in an environment of increasing email database. Relevance characteristics defining class of email in general includes the topic of thee mail and the sender of the email along with the body of email. … …Journal of Computer Science, Vol. 11, Issue 1 · 15 Sep 2014 · 7,832 accessesView PDFCite
Research ArticleOpen accessIn the abstractUNSTEADY BOUNDARY LAYER FLOW ALONG A STRETCHING CYLINDER AN ANALYTICAL SOLUTIONM. Y. AklThe axisymetric laminar boundary layer unsteady flow along a continuously stretching cylinder immersed in a viscous and incompressible fluid is studied. The governing partial boundary layer equations in cylindrical form are first transformed into ordinary differential equations these equations are solved analytically using the optimal modified Homotopy Asymptotic method in order to get a closed form solution for the dimensionless … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 17 Feb 2014 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Design of a Photovoltaic Water Pumping and Treatment SystemAbderrahmen Ben Chaabene, Med Faouzi Elkaroui, Anis SellamiThrough the world, the exploitation of solar energies knew a strong growth these last years. It is interesting to exploit them on the place of consumption, by directly transforming into heat, or in electricity according to needs and especially in remote areas where power from utility is not available or is too costly to install. The use of photovoltaic sources … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 4 Jul 2013 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Middleware for Storing and Querying XML Data in Relational Database Management SystemMohammed Adam Ibrahim Fakheraldien, Jasni Mohamad Zain, Norrozila SulaimanProblem statement: In this study, we propose a middleware that provides a transformation utility for storing and querying XML data in relational databases using model mapping method. Approach: To store XML documents in RDBMS, several mapping approaches can be used. We chose structure independent approach. In this middleware the model mapping method XParent and free of cost available technologies MYSQL, … …Journal of Computer Science, Vol. 7, Issue 2 · 26 Feb 2011 · 7,605 accessesView PDFCite
Research ArticleOpen accessIn the abstractVector Control of a Variable Reluctance Machine Stator and Rotor Discs ImbricatesAbdelhamid BoucettaThis study was devoted, in its first part, to the configuration and the modelling of the Imbricate Discs Variable Reluctance Machine (IDVRM), which was simplified with the assumption of stator structure alike to that of the synchronous machine, leading to the possibility of using the PARK's transformation. Then, a vector control strategy, which maintains a constant saturation level in the … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrating Software Architecture Concepts into the MDA Platform with UML ProfileAdel Alti, Tahar Khammaci, Adel SmedaArchitecture Description Languages (ADLs) provide an abstract representation of software systems. Achieving a concrete mapping of such representation into the implementation is one of the principal aspects of MDA (Model Driven Architecture). Integration of ADLs within MDA confers to the MDA platform a higher level of abstraction and a degree of reuse of ADLs. Indeed they have significantly different platform … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,602 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSynthesis of Baso4 Nanoparticles by Precipitation Method Using Polycarboxylate as a ModifierMohamed El-Shahate Ismaiel Saraya, Inas Mostafa BakrProblem statement: Barium Sulfate (BaSO4) is suitable for many applications because of its whiteness, inertness and high specific gravity. Approach: Nanoparticles of barium sulphate (BaSO4) have been synthesized from barium nitrate by precipitation method in the presence of water soluble organic polycarboxylic polymer as a modifying agent. Transmission electron microscopy, Scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray powder … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 29 Jul 2011 · 15,705 accessesView PDFCite
