Research ArticleOpen accessIn the author namesCombined Thermal Radiation and Mixed Convection in an Inclined Circular DuctW. Lakhal, S. Trabelsi, E. Sediki, M. MoussaProblem statement: Modeling thermal radiation with simultaneous buoyancy and forced convection for real gases flowing inside system with complex geometry is a difficult task encountered in engineering applications. Purpose of this study was to research numerically the interaction of mixed convection and thermal radiation in laminar air flow inside an inclined cylindrical duct with Uniform Wall Heat Flux (UWHF). This … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,292 accessesView PDF Cite

Research ArticleOpen accessIn the author namesStop Conditions Of BB84 Protocol Via A Depolarizing Channel (Quantum Cryptography)Iyed Ben Slimen, Olfa Trabelsi, Houria Rezig et al.BB84 (Bennett and Brassard 1984) is one of the well known protocols of quantum keys distribution. It is built to allow two interlocutors commonly called Alice and Bob to share two similar binary keys and to detect the eavesdropper presence (the eavesdropper is commonly called Eve). However, Eve presence in a disturbed environment causes errors to the sifted keys and … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 7,341 accessesView PDF Cite
