Research ArticleOpen accessIn the abstractQuantum Hadamard Gate Implementation Using Planar Lightwave Circuit and Photonic Crystal StructuresShamsolah Salemian, Shahram MohammadnejadAn all optical method has been proposed for quantum Hadamard gate implementation. This quantum gate was realized by using Y-junction beam splitter. Normal modes in waveguides have been used as quantum bit. This all optical gate can be used in quantum computation and communication. The proposed Hadamard gate has potential of being more compact and easily realized compared to other … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,921 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Bruchid Beetles (Burchidius Arabicus Decelle) Infestation on the Germination of Acacia tortilis (Forssk.) Hayne) SeedsM. Al Jabr AhmedThe role of bruchid beetle infestation on seed germination of Acacia tortilis (Forssk.) Hayne) Mimosaceae under different incubation temperatures and degrees of scarification was studied under controlled conditions. Results indicate that seed germination was highest (96%) in scarified seeds at 25-35°C incubation temperature, whereas, it was only 28% in intact seeds. Seeds infected by bruchid beetles with one or two … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,296 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProximity Aware Routing in Ad Hoc NetworksValerie Alandzi, Alejandro QuinteroMost of the existing routing protocols for ad hoc networks are designed to scale in networks of a few hundred nodes. They rely on state concerning all links of the network or links on the route between a source and a destination. This may result in poor scaling properties in larger mobile networks or when node mobility is high. Using … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,733 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFinite Element Simulation and Parametric Studies of Perfobond Rib ConnectorSuhaib Yahya Kasim Al-Darzi, Ai Rong Chen, Yu Qing LiuSimulating the push-out test and conducting parametric study using finite element model are conducted using perfobond connectors. The finite element model was verified through comparing with push-out test results. The verified finite element model was then used to conduct parametric study aiming to investigate the effect of several parameters, such as height and thickness of connector, cross sectional area and … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 8,218 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Secure Database Encryption SchemeZongkai Yang, Samba Sesay, Jingwen Chen, Du XuThe need to protect database, would be an every growing one especially so in this age of e-commerce. Many conventional database security systems are bugged with holes that can be used by attackers to penetrate the database. No matter what degree of security is put in place, sensitive data in database are still vulnerable to attack. To avoid the risk … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,348 accessesView PDF Cite
