Research ArticleOpen accessIn the abstractNeural-Based Models of Semiconductor Devices for SPICE SimulatorHanene Ben Hammouda, Mongia Mhiri, Zièd Gafsi, Kamel BesbesThe paper addresses a simple and fast new approach to implement Artificial Neural Networks (ANN) models for the MOS transistor into SPICE. The proposed approach involves two steps, the modeling phase of the device by NN providing its input/output patterns, and the SPICE implementation process of the resulting model. Using the Taylor series expansion, a neural based small-signal model is … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 8,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransient Solution of the M/M/C1 Queue with Additional C2 Servers for Longer Queues and BalkingR. O. Al-Seedy, A. A. El-Sherbiny, S. A. EL-Shehawy, S. I. AmmarThe goal of this research is to discuss the M/M/C1 queue with additional C2 servers for longer queues and balking. By using generating function technique the transient probabilities are derived in terms of the modified Bessel function. …Journal of Mathematics and Statistics, Vol. 4, Issue 1 · 31 Mar 2008 · 7,422 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Pile- Soil Interaction Subjected to Lateral Loads in Layered SoilsA. Avaei, Abdoul R. Ghotbi, M. AryafarTo stabilize infrastructures such as tall buildings, bridges, etc., piles are used to resist lateral loads created from earth pressure, wind, waves and earthquake extensively. Pile design requires understanding of how the load is transferred from a pile to surrounding soil and vice versa. Pile properties, soil stress-strain behavior and pile-soil interaction play important roles in pile-response subjected to lateral … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Production Planning of Electricity from Coal-Fired Power Plant Networks under Environmental ConsiderationsHabib H. Al-Ali, Yousef Saif, Ali Elkamel, Ali LohiIn this study, electricity production from a network of coal power plants and under environmental constraints is considered. Several pollutants are incorporated into the decision planning process including nitrogen oxides (NOx), sulfur oxides (SOx) and mercury (Hg). A Nonconvex Mixed Integer Nonlinear Programming (MINLP) model was first developed to assist in the evaluation process. An exact linearization of the nonconvex … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Mar 2008 · 7,074 accessesView PDFCite
Research ArticleOpen accessIn the abstractRat Cardiomyocytes Express a Classical Epithelial Beta-DefensinAnnika Linde, Gerald H. Lushington, Frank Blecha, Tonatiuh MelgarejoBeta-defensins (BDs) are classical epithelial antimicrobial peptides of immediate importance in innate host defense. Since recent studies have suggested that certain BDs are also expressed in non-traditional tissues, including whole heart homogenate, and because effector molecules of innate immunity and inflammation can influence the development of certain cardiovascular disease processes, we hypothesized that BDs are produced by cardiomyocytes as a … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,000 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeographic Distribution and Genetic Analysis of Physiological Racesof Setosphaeria turcica in Northern ChinaJingao Dong, Yongshan Fan, Xiumei Gui et al.Five hundreds and forty-six isolates of Setosphaeria turcica, the causal agent of Northern Corn Leaf Blight, were collected in 61 corn-growing locations throughout six provinces of Northern China during 2000-2002, to determine their pathogenicity on two sets of host differentials: OH43/Huangzao4, OH43Ht1Huangzao4Ht1, OH43Ht2/Huangzao4Ht2, OH43Ht3/Huangzao4Ht3 and OH43HtN/Huangzao4HtN. The isolates were grouped into 13 different physiological races (0, 1, 12, 3, 13, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,809 accessesView PDFCite
Research ArticleOpen accessIn the abstractRoad Transport Congestion Costs Calculations Adaptation to Engineering ApproachMarjan Lep, Beno MesarecThe article represents so called "engineering" approach for computing the total road transport congestion costs. According to economic welfare theory, the total costs of transport congestion are defined as dead weight loss (DWL) of infrastructure use. With a set of equations DWL could be formulated in a mathematical way. Because such form of equation is not directly applicable for concrete … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 6,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethamphetamine Inhibits β-Chemokines and Co-Stimulatory Molecule Expression by Dendritic CellsMadhavan P.N. Nair, Jose W. Rodriguez, Irina M. Borodowsky et al.The US is currently experiencing a serious epidemic of methamphetamine (Meth) use entangled with HIV-1 infection. Blood monocyte derived dendritic cells (DC ) are the first line of defense against HIV-1 infection and are the initial target of HIV-1 in injection drug users. Chemokines are known to be HIV-1 suppressing molecules and are positively associated with non- progression of HIV … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 6,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractGamma Radiosensitivity Study on Long Bean (Vigna sesquipedalis)Ellyfa Kon, Osumanu Haruna Ahmed, Shaharudin Saamin, Nik Muhamad Ab. MajidThis study was conducted to determine the LD50 and effect of gamma ray on germination percentage, plant height, survival percentage, root length, root dry weight and shoot dry weight of seedlings derived from seeds of long bean (Vigna sesquipedalis). Seeds of this crop were treated with 300, 400, 500, 600 and 800 Gy gamma rays at Malaysian Institute of Nuclear … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,601 accessesView PDFCite
