Research ArticleOpen accessIn the abstractNumerical Study of the Moving Boundary Problem During Melting Process in a Rectangular Cavity Heated from BelowY. Jellouli, R. Chouikh, A. Guizani, A. BelghithWe present an analysis of the melting process in Phase Change Materials (PCM) in a horizontal cavity heated from below, driven by the coupling of transient heat conduction in the solid phase and steady state laminar natural convection in the liquid phase with one of the boundaries of the solution domain that moves. We state the problem in the Cartesian … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractCASRA+: A Colloquial Arabic Speech Recognition ApplicationRamzi A. Haraty, Omar El ArissThe research proposed here was for an Arabic speech recognition application, concentrating on the Lebanese dialect. The system starts by sampling the speech, which was the process of transforming the sound from analog to digital and then extracts the features by using the Mel-Frequency Cepstral Coefficients (MFCC). The extracted features are then compared with the system's stored model; in this … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 7,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Quality Control and Everyone’s Participation in Japan to Prevent Pollution During Last Five DecadesMohammed Matouq, Nasir Kloub, Kazue InoueEconomic Growth in Japan after World War II was very remarkable and products from its manufacturing industry were widely accepted in the world market after productivity and quality of them were tremendously improved. On the other hand, Japan soon found itself in severe environmental deterioration, due to not being paid any attention to environment. However, that pollution from industry was … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 7,999 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Temperature and pH on the Stability and Colorimetric Measurement of Textile DyesA.S. Mahmoud, A.E. Ghaly, S.L. BrooksMost of the textile dye removal techniques operate within temperature and pH ranges of 20-60°C and 2-12, respectively. Both the pH and temperature have been reported to have significant effects on the efficiencies of the dye removal techniques. In this study, the effects of pH and temperature on the stability and color measurement (absorbance) of the textile dye remazol brilliant … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 10,751 accessesView PDFCite
Research ArticleOpen accessIn the abstractRe-organization Impact on the Telekom Malaysia's International Division ProductivityAhasanul Haque, Ali Khatibi, Khaizura KarimInternational Divisions' productivity was perceived to incline towards a downward trend which was contravened in 1996 re-organization objective of Telekom Malaysia. This study aims to analyze the root causes of this setback and recommend the solutions to improve the company's productivity. The method to diagnose the root cause was done through surveys and interviews. The data collection was carried out … …Journal of Social Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,902 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabrication of 3-D Porous Mg/Zn doped Tricalcium Phosphate Bone-Scaffolds via the Fused Deposition ModellingSamar Jyoti Kalita, Melissa FergusonThree dimensionally interconnected porous resorbable beta-tricalcium phosphate (β-TCP) ceramic scaffolds were developed using the indirect fused deposition modelling process. β-TCP was doped with Mg and Zn, separately, to improve its sintering kinetics and facilitate fabrication of viable porous scaffolds. Effects of Mg and Zn on sintering kinetics and densification of β-TCP were studied. Fabricated porous scaffolds were tested for their … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,933 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrom Design Specification to SystemCRachid Boudour, Mohamed T. KimourIn this paper, we present a framework for transforming the design model into SystemC code. Such a framework uses as input UML state machine and object diagrams, which are more and more used as design models in embedded systems. To do this, we have firstly used Poseidon tool for editing the design model and generating the XMI representation, and secondly … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 7,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractAsynchronous NoC Router DesignSami Badrouchi, Abdelkrim Zitouni, Kholdoun Torki, Rached TourkiThe Quality of Service Network on Chip (QNoC) is the most perferment solution that provides low latency transfers and power efficient System on Chip (SoC) interconnect. This study presents an asynchronous NoC router, for use in 2-D mesh-connected networks. It comprises multiple interconnected input and output ports and dynamic arbitration mechanisms that resolve any output port conflicts based on the … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 7,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Plasmid in Production of Acetobacter Xylinum BiofilmsAbbas Rezaee, Sanaz Solimani, Mehdi ForozandemogadamAcetobacter xylinum has the ability to produce cellulotic biofilms. Bacterial cellulose is expected to be used in many industrial or biomedical materials for its unique characteristics. A. xylinum contains a complex system of plasmid DNA molecules. A 44 kilobases (kb) plasmid was isolated in wild type of A. xylinum. To improve the cellulose producing ability of A. xylinum, role of … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 7,501 accessesView PDFCite
Research ArticleOpen accessIn the abstractCodesign Methodology of Real-time Embedded Controllers for Electromechanical SystemsSlim Ben Saoud, Andreas Gerstlauer, Daniel D. GajskiUnder increasing time-to-market pressures in the electric drives industries, the development time of new algorithms and new control systems including their debugging time must be minimized. This requirement can be satisfied only by using a well-defined system-level design methodology and by reducing the migration time between the algorithm development language and the hardware specification language. In this study, we propose … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,449 accessesView PDFCite
