Research ArticleOpen accessIn the abstractMicrostructure Affecting Cutting Quality in Fine Blanking ProcessBopit BubphachotProblem statement: Fine blanking process is a high precision process and worldwide in developed countries. Since specimen does not occur fracture on the cutting edge and it is not necessary to decorate again in the finishing process for the fine blanking which can be reduced some operation steps. For example, if chain wheel of motorcycle is produced by conventional blanking, … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractHyperspectral Remote Sensing for Tropical Rain ForestKamaruzaman Jusoff, Kasawani IbrahimProblem statement: Sensing, mapping and monitoring the rain forest in forested regions of the world, particularly the tropics, has attracted a great deal of attention in recent years as deforestation and forest degradation account for up to 30% of anthropogenic carbon emissions and are now included in climate change negotiations. Approach: We reviewed the potential for air and spaceborne hyperspectral … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Approach of Adaptive Network-Based Fuzzy Inference System Modeling in Laser Processing-A Graphical User Interface (GUI) BasedSivarao, Peter Brevern, N. S.M. El-TayebProblem statement: The power of Artificial Intelligent (AI) becomes more authoritative when the system is programmed to cater the need of complex applications. MATLAB 2007B, integrating artificial intelligent system and Graphical User Interface (GUI) has reduced researchers' fear-to-model factor due to unfamiliarity and phobia to produce program codes. Approach: In this study, how GUI was developed on Matlab to model … …Journal of Computer Science, Vol. 5, Issue 10 · 31 Oct 2009 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Validation of High Performance Liquid Chromatographic Method for the Simultaneous Determination of Ceftazidime and Sulbactam in Spiked Plasma and Combined Dosage form-ZydotamMasoom Raza Siddiqui, Abu Tariq, Manu Chaudhary et al.Problem statement: To develop a sensitive method to determine simultaneously ceftizidime and sulbactam in spiked plasma and combined formulation. Approach: In this study an isocratic High performance liquid chromatographic method with UV detection at 230 nm was described for simultaneous determination of Ceftazidime and sulbactam sodium in plasma and combined dosage form. Chromatographic separation of two drugs was achieved on … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 7,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractInformation Extraction from Hypertext Mark-Up Language Web PagesMahmoud Shaker, Hamidah Ibrahim, Aida Mustapha, Lili Nurliyana AbdullahProblems statement: Nowadays, many users use web search engines to find and gather information. User faces an increasing amount of various HTML information sources. The issue of correlating, integrating and presenting related information to users becomes important. When a user uses a search engine such as Yahoo and Google to seek specific information, the results are not only information about … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 7,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Optical Properties of ZnO-TeO2 Glass SystemH. A.A. Sidek, S. Rosmawati, Z. A. Talib et al.Problem statement: Systematic series of ZnO-TeO2 glasses with mole fraction of 0.10-0.40 ZnO content with an interval of 0.05 were studied to obtain their physical and optical properties. Approach: All the glass samples were synthesized by rapid melting quenching method under controlled conditions, while their refractive indices (n) were measured by the EL X-02C high precision ellipsometer. The room temperature … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 14,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Accuracy of Effort Estimation through Fuzzy Set Representation of SizeCh. Satyananda Reddy, KVSVN RajuProblem statement: The precision and reliability of the effort estimation is very important for the competitiveness of software companies. The uncertainty at the input level of the Constructive Cost Model (COCOMO) yields uncertainty at the output, which leads to gross estimation error in the effort estimation. Fuzzy logic-based cost estimation models are more appropriate when vague and imprecise information was … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Numerical Estimation of Thermal Contact Resistance in Contacting SurfacesM.H. Shojaefard, K. GoudarziFor some manufacturing processes, the heat transfer between the components, the tools and the environment has an effect on tool-life and the accuracy of the formed component. Consequently, the measurement of Thermal Contact Resistance (TCR) is of increasing interest to researchers and industrial engineers participating in the manufacture of high-precision components. A new transient method and measurement apparatus are used … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,451 accessesView PDFCite
