Research ArticleOpen accessIn the abstractDurability Assessment of Cylinder Block for Two Stroke Free Piston Linear Engine using Random LoadingM. M. Rahman, A. K. Ariffin, S. Abdullah et al.This research presents the durability assessment of cylinder block for a two-stroke free piston engine using narrow band approach. The life prediction results are worthy for improving the component design at the very early developing stage. This approach is adequate for periodic loading, however, requires very large time records to accurately describe random loading processes. Fatigue damage in conventionally determined … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Studies of the Determination of Divalent Cadmium, Lead and Copper in the Boiling Medicinal Herbs by Stripping Voltammetry and by Atomic Absorption SpectrometryAhmed Hassan, Jamal A. MayoufCadmium, lead and copper were determined in ten Libyian boiling medicinal herbs samples by differential pulse anodic stripping voltammetry as well as by atomic absorption spectrometry. Voltammetric method was done at Hanging Mercury Dropping Electrode (HMDE) in Briton-Robinson buffer solution of pH ~2.1 at 25± 0.1°C. The sample preparation was carried out by boiling 2.0g of a finely pulverized plant … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,033 accessesView PDFCite
Research ArticleOpen accessIn the abstractBorderline Personality Symptoms and Human Immunodeficiency Virus Risk in Alcohol and Other Drug Abusing Adolescent OffendersJessy G. Dévieux, Robert M. Malow, Rhonda Rosenberg et al.Problem statement: Incarcerated youth with borderline symptomatology represent a particularly at risk-population due to their enggement in risky behaviors. Five hundred twenty two adolescents were assessed for borderline symptomatology (MACI), engagement in risky behaviors and attitudes/knowledge. Approach:Adolescents were divided into two groups: low borderline (below the 60 scale score cutoff) and high borderline (subclinical and clinical range). Multivariate analyses were … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 7,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractVerifying Complex Interaction between Hardware ProcessesKiran Ramineni, Shireesh Verma, Ian G. HarrisProblem statement: Verification of correct functionality of semiconductor devices has been a challenging problem. Given the device fabrication cost, it is critical to verify the expected functionality using simulations of executable device models before a device manufactured. However, typical industrial scale devices today involve large number of interactions between their components. Complexity of verifying all interactions becomes almost intractable even … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of the Mean of Truncated Exponential DistributionFaris Muslim Al-AthariProblem statement: In this study, the researcher considers the problem of estimation of the mean of the truncated exponential distribution. Approach: This study contracted with maximum likelihood and unique minimum variance unbiased estimators and gives a modification for the maximum likelihood estimator, asymptotic variances and asymptotic confidence intervals for the estimators. The properties of these estimators in small, moderate and … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,682 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Manganese Uptake by Wetland PlantsA.E. Ghaly, A. Snow, M. KamalThe aim of this study was to assess the kinetics of Mn removal by broad-leaved cattail, soft stem bulrush, soft rush and wool grass plants from contaminated wastewater under laboratory conditions. The approach used was based on a first order kinetic model which depended on the initial heavy metal concentration in the wastewater and allowed for the evaluation of the … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,327 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Modeling of Laterally Loaded PilesS.T. Kok, Bujang B.K. HuatDesign of laterally loaded piles due to soil movement relies on a number of theoretical and numerical approaches. However, the magnitude of soil movement is difficult to estimate with reasonable confidence and accuracy. Finite Element Analysis (FEA) offers an excellent alternative to study pile-soil interaction and pile’s response under lateral loading due to soil movement. This research presents published analytical … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Iron Uptake by Wetland PlantsA.E. Ghaly, A. Snow, M. KamalThe aim of this study was to assess the kinetics of Fe removal by broad-leaved cattail, soft stem bulrush, soft rush and wool grass plants from contaminated wastewater under laboratory conditions. The approach used was based on a first order kinetic model which allowed for the evaluation of the specific metal uptake rate and the maximum accumulation of the metal … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Design Strategy for Volumetric Efficiency Improvement in a Multi-cylinder Stationary Diesel Engine and its Validity under Transient Engine OperationP. Seenikannan, V.M. Periasamy, P. NagarajThis paper proposes an approach to improve engine performance of volumetric efficiency of a multi cylinder diesel engine. A computer simulation model is used to compare volumetric efficiency with instantaneous values. A baseline engine model is first correlated with measured volumetric efficiency data to establish confidence in the engine model's predictions. A derivative of the baseline model with exhaust manifold, … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,502 accessesView PDFCite
