Research ArticleOpen accessIn the abstractHarmonics Study and Comparison of Z-source Inverter with Traditional InvertersB. Justus Rabi, R. ArumugamThis paper presents an Impedance Source Inverter for A.C electrical drives. The impedance source inverter employs a unique impedance network cable with inverter main circuit and rectifier. By controlling the shoot-through duty cycle, the z-source inverter system using MOSFETS provide ride-through capability during voltage sags, reduces line harmonics, improves power factor and high reliability, and extends output voltage range. Analysis, … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,281 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Proposed Optical Music Mark Recognition SystemIsmael JannoudThe optical music symbol recognition system still has many challenges. Most of issues focused on the recognition of the individual marks in the input concert documents. In this study a new and efficient model for optical music recognition (OMR) was proposed. The music marks was recognized and played by the computer OMR system automatically. A stored file of music documents … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 4,890 accessesView PDFCite

Research ArticleOpen accessIn the abstractAutomatic Discovery of Association Paths in Relational Databases Using Software VisualizationHaider Ali RamadhanWe introduce a visual framework for facilitating tasks associated with database maintenance and re-use. The prototype system embodying the framework is presented. The system utilizes various techniques and features of software visualization. The system supports visual displays of the database structure along with various implicit relationships found in it such as associations and path views. Information visualized is automatically extracted … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Intelligent Multilingual Mouse Gesture Recognition SystemNidal F. Shilbayeh, Mahmoud Z. IskandaraniA comprehensive mouse gesture system is designed and tested successfully. The system is based on UNIPEN algorithm in terms of mouse movements and applies its geometrical principles such as angles and transposition steps. The system incorporates Neural Networks as its learning and recognition engine. The designed algorithm is not only capable of translating discrete gesture moves, but also continuous sentences … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 7,126 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of an Input Queuing Packet SwitchAzeddine Bilami, Mustapha Lalam, Mohamed BenmohammedMany Architectures of Internet routers, ATM and Ethernet switches have been proposed and analysed in literature. Theoretically reliable and valid solutions have been developed to achieve high performances, but a lot of them are not feasible in practice for commercial and technological reasons. Few papers develop the implementation and simulation aspects. The objective of this study is the design of … …Journal of Computer Science, Vol. 1, Issue 3 · 19 Sep 2005 · 6,926 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Reliability and Availability Characteristics of Two Different Systems by Using Linear First Order Differential EquationsKhaled M. El-Said, Mohamed S. EL-SherbenyThis study deals with the reliability and availability characteristics of two different series system configurations. The second system differs from the first system due to the additional feature of preventive maintenance. The failure times of a components are assumed to be exponentially distributed with parameters α,β,α' and β', respectively. The replacement time distribution of each server is also exponentially distributed … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Chord Length Distribution Along an Edge: The Wedge Case and the Quadratic Rod CaseWilfried GilleThe analytic expression is given for the chord length distribution density f(l,b) along the edge of an infinitely long rectangular wedge and for a quadratic rod, both of constant breadth b. The general result is: A constant behaviour for 0 < l < b and a finite jump of size 2/b at l = b is an intrinsic feature of … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Analysis and Design of the Enhanced Firewall for Intranet SecurityU. K. Singh, A. K. Ramani, N. S. ChaudhariIntranet often employ an Internet firewall to mitigate risks of system penetration, data theft, data destruction and other security breaches. Conventional Internet firewalls impose an overly simple inside vs. outside model of security that is incompatible with many business practices that require extending limited trust to external entities. Additionally, firewall security perimeters are somewhat weak: they provide no protection from … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,709 accessesView PDFCite
