Research ArticleOpen accessIn the abstractRobust and Blind Watermarking of Relational Database SystemsA. Al-Haj, A. OdehProblem statement: Digital multimedia watermarking technology was suggested in the last decade to embed copyright information in digital objects such images, audio and video. However, the increasing use of relational database systems in many real-life applications created an ever increasing need for watermarking database systems. As a result, watermarking relational database systems is now merging as a research area that … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,504 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Authoring Tool for As-in-Class E-lectures in E-learning SystemsNael HirzallahThis study lists and discusses the basic features that any E-Learning system should consider. It also proposes an authoring algorithm, namely Slide Generating Algorithm that uses the Authoring-on-the-Fly approach to create electronic course content from real lectures.

Research ArticleOpen accessIn the abstractMobility Management Technique for Real Time Traffic in 802.11 NetworksGurpal Singh, Ajay Pal Singh Atwal, B.S. SohisA practical mobility management technique aimed at reducing handoff latency to less than 10ms has been proposed and implemented in this paper. Handoff latency has been reduced by decoupling scanning from handoff execution process. This scheme has been implemented in the form of client side application with modifications to open source Madwifi new generation driver. Performance of this mobility management … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,779 accessesView PDFCite
Research ArticleOpen accessIn the abstractHiding a Large Amount of Data with High Security Using Steganography AlgorithmNameer N. EL-EmamThis study deals with constructing and implementing new algorithm based on hiding a large amount of data (image, audio, text) file into color BMP image. We have been used adaptive image filtering and adaptive image segmentation with bits replacement on the appropriate pixels. These pixels are selected randomly rather than sequentially by using new concept defined by main cases with … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 8,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Bit Error Rate Performance of Multi Tone Channel Utilising De-OQPSK and De-Off Set 16 QAM with Guard IntervalIbrahim A.Z. QatawnehDigital communications systems use Multi tone Channel (MC) transmission techniques with differentially encoded and differentially coherent demodulation. Today there are two principle MC application, one is for the high speed digital subscriber loop and the other is for the broadcasting of digital audio and video signals. In this study the comparison of multi carriers with OQPSK and Offset 16 QAM … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,847 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntensity Position Modulation for Free-Space Laser Communication SystemF. Faghihi, A. JangjooIn this study a novel analog modulation-demodulation technique for free-space laser communication system called Intensity Position Modulation (IPM) is carried out. According to TEM00 mode of a laser beam and by linear fitting on the Gaussian function as an approximation, the variation of the linear part on the reverse biased pn photodiode produced various currents. Our simulated results show fine … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,601 accessesView PDFCite
