Research ArticleOpen accessIn the keywordsDesign Analysis of An Electromagnetic Band Gap Microstrip AntennaM.S. Alam, M.T. Islam, N. MisranProblem statement: Wideband compact antenna is highly demandable due to the dynamic development in the wireless technology. Approach: A simple, compact EBG microstrip antenna is proposed in this study that covers a wideband of 250 GHz and the design is conformal with the 2.45 GHz ISM band (WLAN, IEEE 802.11b and g)/Bluetooth/RFID applications. Results: A 6×6 array of square unit … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 27 Oct 2011 · 7,373 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Study of Elementary School Students' Viewpoints on Interactive WhiteboardTian-Syung Lan, Tsung-Yen HsiaoProblem statement: Introducing the Interactive Whiteboard (IWB) into teaching is not only a current trend but also a major policy of education. Many studies indicated that IWB can increase the interaction between teachers and students as well as students’ motivation and enjoyment from teachers’ viewpoints. However, a study to understand and describe the opinion from children’s view is hardly found. … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 7,443 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Web-Based Rapid Prototyping Workflow Management Information System for Computer Repair and MaintenanceA. H. El-Mousa, Z. J. Muhsin, M. A. Al-TaeeProblem statement: Response to paper-based requests for computer and peripheral repair and maintenance has become very troublesome and slow due to the large demand and expansion at the University of Jordan. The objectives of this study were to: (i) investigate the current system processes associated with the paper-based workflow system. (ii) design and implement, using a suitable workflow management approach, … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2009 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the keywordsQuantum Key Distribution Using Decoy State ProtocolSellami Ali, Shuhairi Saharudin, M. R.B. WahiddinProblem statement: Quantum key distribution provides unconditional security guaranteed by the fundamental laws of quantum physics. Unfortunately, for real-life experimental set-ups, which mainly based on faint laser pulses, the occasional production of multi-photons and channel loss make it possible for sophisticated eavesdroppers to launch various subtle eavesdropping attacks including the Photon Number Splitting (PNS) attack. The decoy state protocols recently … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,441 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBluetooth Wireless Network Authentication Using Radio Frequency Communication ProtocolGhossoon M. Waleed, M. Faizal, R. B. Ahmad et al.Problem statement: Bluetooth has emerged as very popular ad hoc network standard today. Bluetooth network applications include wireless synchronization, e-mail/internet/intranet access using local personal computer connections, hidden computing through automated applications and networking. Due to this ability, it is not impossible for the network to receive any attack. Approach: In this study, we developed an algorithm to build new software … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 7,823 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Robustness for Convex Optimization Applied to Array Antenna Pattern SynthesisRichard Torrealba, David H. Covarrubias, Marco PanduroThis study presents an analysis of the convex optimization applied to the synthesis of the radiation pattern for linear antenna arrays. This study emphasizes the application of the convex optimization for the array pattern synthesis considering the simultaneous elimination of several zones interferences, reduction of the level of power in two space zones densely populated by interferences, as well as … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,570 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRandom Graph Generation Based p-Method and Box Method for the Evaluation of Power-Aware Routing Protocols of Ad hoc NetworksSaleh H. Al-SharaehThe objective of this paper is to investigate the best solution such that on which decision should be made to forward a wireless packet. The decision should be made in such a way to keep the node alive by choosing an alternate path, through those nodes that have more power reserve. Minimizing the consumption of the reserve power will results … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,765 accessesView PDFCite
