Research ArticleOpen accessIn the abstractOn Embeddings of Hamiltonian Paths and Cycles in Extended Fibonacci CubesIoana Zelina, Grigor Moldovan, Ioana TascuThe interconnection network is an essential component of a distributed system or of a supercomputer based on large-sale parallel processing. Because in distributed systems the communication between processors is based on message exchange, the network topology is of a great importance. The interconnection network can be seen as a graph and the properties of a network can be studied using … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractGraph Based Segmentation in Content Based Image RetrievalP. S. Suhasini, K. S.R. Krishna, I. V.M. KrishnaProblem statement: Traditional image retrieval systems are content based image retrieval systems which rely on low-level features for indexing and retrieval of images. CBIR systems fail to meet user expectations because of the gap between the low level features used by such systems and the high level perception of images by humans. To meet the requirement as a preprocessing step … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,585 accessesView PDFCite
Review ArticleOpen accessIn the abstractReview of Charge Pump Topologies for Micro Energy Harvesting SystemsMichelle Lim Sern Mi, Md. Shabiul Islam, Jahariah Sampe, Sawal Hamid Md. AliThis paper reviews CMOS based charge pump topologies used within autonomous embedded micro-systems. These charge pump structures have evolved from its simplistic diode-tied, single-branches with major threshold drops to exponential type, dual-branches with sophisticated gate and substrate control for lower voltage operation. Published charge pumps are grouped based on architecture, operation principles and pump optimization techniques with their pros and … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 26 May 2016 · 7,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Anthropomorphic Gripping Manipulator: The Study of Kinematics and Virtual Modeling of GripIvan Vladimirovich Krechetov, Arkady Alekseevich Skvortsov, Pavel Sergeevich Lavrikov, Danil Vladilenovich YatskinThe article is a study into the kinematic scheme of a newly developed anthropomorphic manipulator designed to perform gripping and holding tasks on items from a predefined set. Within the study is the implementation of a mathematical model describing the kinematics of a multilink manipulator using the GraspIt package. The method used in this study allows for the calculation of … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 8 Jan 2016 · 7,682 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Time-Delayed Neural Networks via Rightmost Eigenvalue PositionsSun Yi, Sangseok Yu, Jung H. Kim, Taher M. Abu-LebdehNeural networks have been frequently used in various areas. In the implementation of the networks, time delays and uncertainty are present and known to lead to complex behaviors, which are hard to predict using classical analysis methods. In this study, stability and robust stability of neural networks considering time delays and parametric uncertainty is studied. For stability analysis, the rightmost … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 26 Jan 2015 · 8,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractDEPENDABILITY ATTRIBUTES FOR INCREASED SECURITY IN COMPONENT-BASED SOFTWARE DEVELOPMENTHasan Kahtan, Nordin Abu Bakar, Rosmawati NordinExisting software applications become increasingly distributed as their continuity and lifetimes are lengthened; consequently, the users’ dependence on these applications is increased. The security of these applications has become a primary concern in their design, construction and evolution. Thus, these applications give rise to major concerns on the capability of the current development approach to develop secure systems. Component-Based Software … …Journal of Computer Science, Vol. 10, Issue 7 · 17 Jun 2014 · 7,800 accessesView PDFCite
Research ArticleOpen accessIn the abstractTime-Delay Estimation using the Characteristic Roots of Delay Differential EquationsSun Yi, Wonchang Choi, Taher Abu-LebdehProblem statement: For ordinary dynamic systems (i.e., non-delayed), various methods such as linear least-squares, gradient-weighted least-squares, Kalman filtering and other robust techniques have been widely used in signal processing, robotics, civil engineering. On the other hand, time-delay estimation of systems with unknown time-delay is still a challenging problem due to difficulty in formulation caused. Approach: The presented method makes use … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 7 Apr 2012 · 8,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Pitch Delay Resolution Technique for Tonal Language Speech Coding Based on Multi-Pulse Based Code Excited Linear Prediction AlgorithmSuphattharachai ChomphanProblem statement: In spontaneous speech communication, speech coding is an important process that should be taken into account, since the quality of coded speech depends on the efficiency of the speech coding algorithm. As for tonal language which tone plays important role not only on the naturalness and also the intelligibility of the speech, tone must be treated appropriately. Approach: … …Journal of Computer Science, Vol. 7, Issue 1 · 14 Jan 2011 · 6,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Field Programmable Gate Array Implementation of Basic Building Blocks for Power-Efficient Baugh-Wooley MultipliersMuhammad H. Rais, Bandar M. Al-Harthi, Saad I. Al-Askar, Fahad K. Al-HusseinProblem statement: As growing demands on portable computing and communication systems, the power-efficient multipliers play an important role. In these multipliers basic multiplication follows the Baugh-Wooley algorithms and can easily be implemented using Field Programmable Gate Array (FPGA) devices because the development cost for Application Specific Integrated Circuits (ASICs) are high. These algorithms should be verified and optimized before implementation. … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,129 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,193 accessesView PDFCite
