Research ArticleOpen accessIn the abstractImplementation of CONCEIVER++: An Object-Oriented Program Understanding SystemNor Fazlida Mohd Sani, Abdullah Mohd. Zin, Sufian IdrisProblem statement: Understanding on computer program is a complex cognitive activity. It is ability and also a difficult task especially for novice programmer. The object-oriented languages has widely used in education and industry recently. In programming it is important to have such software which can aid programmers or students to code the program. But, available program understanding systems using the … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractInformation Hiding: A Generic ApproachRiad jabri, Boran Ibrahim, Hadi Al-ZoubiProblem statement: Privacy and security over communication channels are of primary concerns. Due to their complexity and diversity, there is a need for continuous improvements of the adopted solutions. In this study, we consider two of the adopted ones, namely, steganogrphy and cryptography and propose a new information hiding system. Approach: The proposed system was based on a generic approach … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Constructive Neural Network Architecture for Pattern ClassificationS. S. Sridhar, M. PonnavaikkoProblem statement: Constructive neural network learning algorithms provide optimal ways to determine the architecture of a multi layer perceptron network along with learning algorithms for determining appropriate weights for pattern classification problems. These algorithms initially start with small network and dynamically allow the network to grow by adding and training neurons as needed until a satisfactory solution is found. The … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,570 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 · 7,675 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Supervirulence Plasmid pToK47 from Agrobacterium tumefaciens A281 Improves Transformation Efficiency of Hevea brasiliensisP. Arokiaraj, R. Leelawathy, H. Y. YeangProblem statement: The present study investigates the ability of the pTok47 supervirulence plasmid form Agrobacterium tumefaciens A281 to enhance genetic transformation in Hevea brasiliensis. Approach: Hevea anther callus was transformed via Agrobacterium-mediated genetic transformation using two strains of Agrobacterium (GV2260 and GV3850) harboring the human serum albumin cDNA and the supervirulent plasmid pToK47 from Agrobacterium tumefaciens A281. The transformed callus … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 3 · 30 Sep 2009 · 8,927 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Multi-Valued Quaternary Based Analog-to-Digital ConverterA.H.M. Zahirul Alam, Wahab Adetunji Lawal, Sheroz Khan, Muhammad Mahbubur RashidProblem statement: The design of multi-valued quaternary based Analog-to-Digital Converter (ADC) circuit was presented. The ADC generates multi-valued logic outputs rather than the conventional binary output system to overall reduction in circuit complexity and size. Approach: Design was implemented using pipeline ADC architecture and was simulated using model parameters based on standard 0.13 µm CMOS process. Results: Performance analysis of … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,295 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Low Complexity Lossless Coding Algorithm for Medical ImagesS. E. Ghrare, M.A. Mohd. Ali, K. Jumari, M. IsmailProblem statement: Nowadays a large number of various medical images are generated from hospitals and medical centers with sophisticated image acquisition devices, the movement toward digital images in radiology presents the problem of how to conveniently and economically store, retrieve and transmit the volume of digital images. Thus digital image data compression is necessary in order to solve this problem. … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Combinational Circuits for Control PurposesMaher A. Nabulsi, Mohammed A.F. Al-HusainyProblem statement: Combinational circuits are used in computers for generating binary control decisions and for providing digital components for data processing. Approach: The use of combinational circuits and logic gates to control other circuits was discussed. Different systems that use logic gates, multiplexers, decoders and encoders to control different circuits were presented. This study presented a design and implementation of … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 7,242 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtection for an Immediate Split Structure of Tree-Based EPON Architecture-Ideal Condition AnalysisMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran JumariProblem statement: Ethernet Passive Optical Network (EPON) was proposed to overcome the bandwidth bottleneck at the Access Networks due to its simplicity, cost effective and wide spread deployment. A failure in access networks can cause serious problems, because access network transmit aggregated high speed traffic from hundreds of subscribers. Protection and restoration mechanisms have been applied in backbone networks, but … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,280 accessesView PDFCite
