Research ArticleOpen accessIn the abstractSimilarity Solutions for Free Convection Between Two Parallel Porous Walls at Different TemperaturesA. J. Omowaye, O. K. KorikoProblem statement: A two dimensional steady laminar free convective flow of viscous incompressible fluid between two parallel porous walls is considered. Approach: Using the similarity variable, the partial differential equations were reduced to ordinary differential equations. The coupled ordinary differential equations were solved numerically using shooting method. The effect of various physical parameters, such as the Prandtl number, Grashof number, … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,783 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomated Position System Implementation over Vehicular Ad Hoc Networks in 2-Dimension SpaceSoumen Kanrar, Mohammad SirajProblem statement: The real world scenario have changed from the wired connection to wireless connection. Over the years software development has responded to the increasing growth of wireless connectivity in developing network enabled software. The problem arises in the wireless domain due to random packet loss in transport layer and as well as in data link layer for the end … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware Implementation of a Genetic Algorithm Based Canonical Singed Digit Multiplierless Fast Fourier Transform Processor for Multiband Orthogonal Frequency Division Multiplexing Ultra Wideband ApplicationsMahmud Benhamid, Masuri B. OthmanProblem statement: Ultra Wide Band (UWB) technology has attracted many researchers' attention due to its advantages and its great potential for future applications. The physical layer standard of Multi-band Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB system is defined by ECMA International. In this standard, the data sampling rate from the analog-to-digital converter to the physical layer is up to 528 … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,515 accessesView PDFCite

During study, the most promising technology capable of delivering full service access at high data rates … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2009 · 6,962 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Modeling and Flooding in Ad-hoc Wireless NetworksO. Issaad, S. Pierre, G. I. Ivascu, O. GarciaThis study proposes a new modeling approach for wireless ad-hoc networks. The new approach is based on the construction of fuzzy neighborhoods and essentially consists of assigning a membership or importance degree to each network radio link which reflects the relative quality of this link. This approach is first used to model the flooding problem and then an algorithm is … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,015 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltra Wide Band (UWB) Ad-hoc Networks: Review and TrendsRashid Saeed, Sabira Khatun, Borhanuddin M. Ali, Mohd K. AbduallahShort-range wireless systems have recently gained a lot of attention to provide seamless, multimedia communications around a user-centric concept in so called Wireless Personal Area Networks (WPAN). Ultra-Wide Band (UWB) technology presents itself as a good candidate for the Physical Layer (PHY) of WPAN, both for high and low data rate applications. Many ongoing developments of Ultra-Wide Band (UWB) system … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 7,060 accessesView PDFCite
