Research ArticleOpen accessIn the abstractAdaptive Resonance Theory 1 (ART1) Neural Network Based Horizontal and Vertical Classification of 0-9 Digits RecognitionMbaitiga ZacharieThis study describes the Adaptive Resonance Theory 1 (ART1), an efficient algorithm that emulates the self-organizing pattern recognition and hypothesis testing properties of the ART neural network architecture for horizontal and vertical classification of 0-9 digits recognition. In our approach the ART1 model can self-organize in real time producing stable and clear recognition while getting input patterns beyond those originally … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 7,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Reconfigurable Execution Core for Merged DSP MicrocontrollerA. K. Rath, P. K. MeherThe study presents an execution core which can be reconfigured either for calculation of digital convolution or for computation of discrete orthogonal transform by appropriate local buffer initialization of processing cells. It is shown that the data flow pattern can be changed by a single bit control signal. The proposed core can be connected to port 1 of Intel 8051 … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,487 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost Elasticities of Reliability and MTTF for k-out-of-n SystemsAli Muhammad Rushdi, Abdulaziz Efain AlsulamiThe application of the concept of cost elasticity of reliability was extended from the parallel system to the partially redundant or k-out-of-n:G(F) system (or k-out-of-n system, for short). An expression for the cost elasticity of reliability was derived for a general k-out-of-n system. The expression yielded acceptable results for a wide range of values for k, n, and component reliability. … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 7,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractFoundry Wastes Reuse and Recycling in Concrete ProductionSilvia Fiore, Maria Chiara ZanettiThe industrial process of a cast iron foundry plant located in the North of Italy was analyzed in order to determine the amount and kind of produced wastes. The main fractions are core and moulding sands, muds and powders from dust abatement plants, furnace and ladle slags, and exhaust lime, making about 750-800 t/d of residues for a production of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractAd Hoc Mobile Wireless Networks Routing Protocols - A ReviewGeetha Jayakumar, G. GopinathMobile ad hoc networks(MANET) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self organize into arbitrary and temporary ad-hoc network topologies, allowing people and devices to seamlessly internet work in areas with no preexisting communication infrastructure e.g., disaster recovery environments. An ad-hoc network is not a new one, having been around in various forms … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 115,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Profile of Some Heavy Metal Ions Adsorption Onto Biomaterial SurfacesMedhat A. ShakerThe adsorption of Co2+, Zn2+, Pb2+ and Hg2+ onto dried non-living biomass (NB) of different Pseudomonas strains has been investigated in detail. Maximum adsorption of these cations is achieved at optimum pH values from 3.5 to 4.5 to avoid hydrolysis, polymerization and precipitation of metal cations in the treatment solutions. The experimental data obtained at different temperatures were fitted to … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of 16-point Radix-4 Fast Fourier Transform in 0.18µm CMOS TechnologySiva Kumar Palaniappan, Tun Zainal Azni ZulkifliThis paper introduces detail design of semi-custom CMOS Fast Fourier Transform (FFT) architecture for computing 16-point radix-4 FFT. FFT is one of the most widely used algorithms in digital signal processing. It is used in many signal processing and communication application as an important block for various multi-carrier systems such as for WLAN (Wireless local area network). This paper describes … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractCorrosion of Copper Metal in Presence of Binary MixturesMedhat A. Shaker, Hanaa H. Abdel-RahmanThe rates of copper corrosion were determined in presence and in absence of different compositions of water-ethanol, -ethylene glycol, -glycerol, -dimethyl sulfoxide (DMSO) and -dioxane binary mixtures. The rates of corrosion were found to decrease by increasing the concentration of solvents. The percent inhibition range from 10.9 to 78.2% depends on the nature of solvent and its concentration.

HamzaAlthough treatment with therapeutic agents may be one of the main causes of liver toxicity, there have been only limited attempts at thorough research efforts to seek solution. Diclofenac (DIC) is a widely used anti-inflammatory drug that causes liver toxicity. This DIC-induced hepatotoxicity was found to be associated with oxidative damage.

Research ArticleOpen accessIn the abstractThe NifX Protein is Involved in the Final Stages of FeMo-cofactor Transport to the MoFe ProteinSurobhi Lahiri, Byron Cole, Lakshmi Pulakat, Nara GaviniThe nitrogenase enzyme catalyzes the reduction of dinitrogen to ammonia and is composed of the Fe and MoFe proteins. The iron molybdenum cofactor (FeMo-co) of the MoFe protein is the site of active substrate reduction. The NifX protein has also been suggested to have a role in the FeMo-co synthesis, although its exact role is still open to investigation.
