Research ArticleOpen accessIn the keywordsHARDWARE REALIZATION OF HIGH SPEED ELLIPTIC CURVE POINT MULTIPLICATION USING PRECOMPUTATION OVER GF(P)N. Shylashree, V. SridharTwo new theoretical approaches for the hardware realization of high speed elliptic curve point multiplication over a prime field (GF(p)) are presented. These hardware implementations use multiple units of elliptic curve point doublers, point adders and multiplexers. The modular hardware approach used here provides high speed and scalability. …Journal of Computer Science, Vol. 10, Issue 7 · 4 Feb 2014 · 6,614 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDistributed Amplify and Forward Cooperation While Maintaining Transmission FreedomL. Chen, R. Carrasco, I. WassellProblem statement: This study proposes a novel Distributed Amplify and-Forward (DAF) cooperative scheme, achieving higher diversity order and yet maintaining the same transmission freedom as the conventional Amplify-and-Forward (AF) scheme. In the DAF scheme, a user’s transmitted symbols are partitioned into several sequences in order to be relayed by different users. Approach: In the cooperative network, each user still uses … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 2 Aug 2012 · 7,379 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCustomer-Made 3×3 Polymer Optical Fiber Splitter Based on Green Technology using Fusion TechniqueMohammad Syuhaimi Ab-Rahman, Nik Nur Syahirah Mohammad, Hadi Guna et al.Problem statement: Polymer Optical Fiber (POF) has many advantages making it the choice of today’s communication, especially in automotive industry. This communication requires low cost ways for much information to be sent simultaneously. Because of this, using Wavelength Division Multiplexing (WDM) concept, a low cost and green 3×3 POF splitter is fabricated. It is fabricated using cheap and easy-to-find tools … …Journal of Computer Science, Vol. 8, Issue 4 · 11 Feb 2012 · 6,848 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPerformance Analysis of Different Optical Switching ArchitecturesSalman Ali Al-QahtaniProblem statement: Optical Packet Switching (OPS) and transmission networks based on Wavelength Division Multiplexing (WDM) have been increasingly deployed in the Internet infrastructure over the last decade in order to meet the huge increasing demand for bandwidth. Several different technologies have been developed for optical packet switching such as space switches, broadcast-and-select, input buffered switches and output buffered switches. These … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,334 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsUsing 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.

Research ArticleOpen accessIn the keywordsThe Relationship between Exclusive-Or and the Unique Existential QuantifierM. A. Nabulsi, A. M. AbdallaProblem Statement: The efficiency of computer architecture design is affected by the components used. Establishing a relationship between exclusive-or (XOR) and the unique existential quantifier provides alternative system implementations. Approach: Applications of XOR and the unique existential quantifier were explained. Then, prepositional logic was used to establish the relationship between them. Results: Different quantified assertions with two variables that use … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 7,475 accessesView PDF Cite

Short CommunicationsOpen accessIn the keywordsMolecular Testing for Respiratory Tract Infections May Have Favorable Impact on Real-world Healthcare CostsAzia Evans, Vijay Singh, Pallavi Upadhyay et al.Molecular testing by Polymerase Chain Reaction (PCR) has improved diagnostic performance to inform appropriate treatment.
