Research ArticleOpen accessIn the abstractA New Error Correction Intuitive Approach in Quantum Communications ProtocolsAris Skander, Merabtine Nadjim, Malek BenslamaQuantum Error Correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication. We develop a general theory of quantum error correction based on encoding states into larger Hilbert spaces subject to known interactions. We obtain necessary and sufficient conditions for the perfect recovery of an encoded state after its degradation by … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Levan by Bacillus licheniformis for Use as a Soil Sealant in Earthen Manure Storage StructuresAbdel E. Ghaly, F. Arab, N.S. Mahmoud, J. HigginsManure application is not permitted on frozen land in Canada and therefore, manure management and storage are the primary issues facing the agri-food industry. Low-cost, effective and environmentally safe earthen manure storage (EMS) facilities will lower costs and help make the livestock industry more competitive and efficient. The goal of this study was to develop a biological sealing technology for … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractApproaches for Categorization of Reusable Software ComponentsParvinder Singh Sandhu, Janpreet Singh, Hardeep SinghReuse repositories manager manages the reusable software components in different categories and needs to find the category of reusable software components. In this paper, we have used different pure and hybrid approaches to find the domain relevancy of the component to a particular domain. Probabilistic Latent Semantic Analysis (PLSA) approach, LSA, Singular Value Decomposition (SVD) technique, LSA Semi-Discrete Matrix Decomposition … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 6,902 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputer-Based Drift Radar System Design for Ionspheric Irregularities Measurements and AnalysisMusbah J. Aqel, Mohamd Al-EwiessiA computer based drift radar system has been designed for real time ionspheric irregularities measurements where closely spaced receiver technique has been utilized. A computerized interface with the system a long with real time software has been developed to keep tracking of the measured data for further analysis. The system has been implemented at locations and produced a reliable analysis. …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 6,725 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Filtering Algorithm for Duplicate Document Based on Concept AnalysisAhmad M. HasnahData bases and web pages contain currently a huge number of duplicate document. It is then fundamental to have a filter which can be embedded, for instance, within an information retrieval system like a search engine in order to prohibit the redundant documents references to appear on the screen as a reply to the user's query. This filter can save … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling of Transient Heat Flux in Spark Ignition Engine During Combustion and Comparisons with ExperimentT. F. Yusaf, Sye Hoe, Fong et al.A quasi-one dimensional engine cycle simulation program was developed to predict the transient heat flux during combustion in a spark ignition engine. A two-zone heat release model was utilized to model the combustion process inside the combustion chamber. The fuel, air and burned gas properties throughout the engine cycle were calculated using variable specific heats. The transient heat flux inside … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,173 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Light Weight Ceramics Teils from Local MaterialsGhazi Al-MarahlehThis study covers the feasibility of production lightweight ceramics teils (light weight clay bricks) by adding local various types of combustible materials to the clay. It was found those substantial quantities of bagasse, sawdust, rice husks and straw are suitable for the production of lightweight bricks and distributed combustible materials finely was mixed with clay and molded into bricks. During … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Theorem of Hunt for Semidynamical SystemsMounir Bezzarga, Gheorghe BucurThe main result of this paper provides a direct proof of a Hunt's Theorem of the classical potential theory for the so called local semidynamical systems in non locally compact infinite dimensional spaces. …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractLinks between Dynamic Physical Systems and Operator Theory Issues Concerning Energy Balances and StabilityM. D.L. SenThis study relates the properties of operators with the well- known concepts of positive realness and passivity properties in dynamic systems and their associate transfer functions. Those concepts together with very close related ones are first examined from a physical point of view. Then, they are related to hyper-stability and properties of transfer functions while the hyper-stability theorem is revisited … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,826 accessesView PDFCite
