Research ArticleOpen accessIn the abstractAdjustment of Peak Streamflows of a Tropical River for UrbanizationAta Amini, Thamer Mohammad Ali, Abdul Halim B Ghazali, Bujang Kim HuatPeak runoff from a catchment is influenced by many factors such as intensity and duration of rainfall, catchment topography, catchment shape, land use and other variables. For a particular catchment, landuse change and other human activities will alter the characteristic of catchment hydrograph. Problem statement: As a result of urbanization, the magnitude of floods occurring in a catchment increased. It … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,546 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCalibration and Simultaneous Monitoring of Soil Water Content and Salinity with Capacitance and Four-electrode ProbesTadaomi Saito, Haruyuki Fujimaki, Mitsuhiro InoueNon-destructive monitoring of soil water content (W) and the electrical conductivity of the soil solution (ECw) has been desired for environmental evaluation and sustainable agriculture. Dielectric probes and four-electrode probes are widely used for the non-destructive determination of W and the soil bulk electrical conductivity (ECb), respectively. Since the output of dielectric probes is affected by soil salinity, the calibration … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,918 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign of Economical Equipment for Water and Fuel Level Detection in JordanAli M. OthmanBoth a cold and hot water supplies in Jordan are provided by indirect systems and so is the fuel supply for central heating, by using storage tanks placed over the buildings roofs. This requires climbing to the roofs for measuring the level of fluid in these tanks. This method is primitive, impractical and tedious. A simple reliable easing system is … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,584 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Higher Order Dispersion Terms in the Nonlinear Schrodinger EquationRobert Beech, Frederick OsmanThis study presents a concise graphical analysis of solitonic solutions to a nonlinear Schrodinger equation (NLSE). A sequence of code using the standard NDSolve function has been developed in Mathematica to investigate the acceptable accuracy of the NLSE in relatively small ranges of the dispersive parameter space. An operator splitting approach was used in the numerical solutions to expand the … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,491 accessesView PDF Cite
