نویسندگان

چکیده

• Analytical solution to nonlinear routing with arbitrary power-law storage function is presented. Constant inflow produces incomplete beta outflow. Explicit Lambert-W outflow for linear storage-depth orifice outlet provided. A new analytical a general The resulting implicit solution, expressed in terms of the function, valid hydrographs that may be represented by series pulses widths. thus extends existing solutions reported literature which are only specific exponents function. An explicit also presented reservoirs storage-elevation relationship and single or submerged sluice gate outlet. To support practical design applications demonstrate utility we provide approximate four simple applications. results show that, being exact, not subject numerical errors instabilities hence used variety modeling, design, optimization, forecasting, control involving functions.

Analytical Soliton Solutions Modeling of Nonlinear Schrödinger Equation with the Dual Power Law Nonlinearity  

Introduction In this study, we use a newly proposed method based on the software structure of the maple, called the Khaters method, and will be introducing exponential, hyperbolic, and trigonometric solutions for one of the Schrödinger equations, called the nonlinear Schrödinger equation with the dual power law nonlinearity. Given the widespread use of the Schrödinger equation in physics and e...

Analytical-Approximate Solution for Nonlinear Volterra Integro-Differential Equations

In this work, we conduct a comparative study among the combine Laplace transform and modied Adomian decomposition method (LMADM) and two traditional methods for an analytic and approximate treatment of special type of nonlinear Volterra integro-differential equations of the second kind. The nonlinear part of integro-differential is approximated by Adomian polynomials, and the equation is reduce...

ANALYTICAL-NUMERICAL SOLUTION FOR NONLINEAR INTEGRAL EQUATIONS OF HAMMERSTEIN TYPE

Using the mean-value theorem for integrals we tried to solved the nonlinear integral equations of Hammerstein type . The mean approach is to obtain an initial guess with unknown coefficients for unknown function y(x). The procedure of this method is so fast and don't need high cpu and complicated programming. The advantages of this method are that we can applied for those integral equations whi...

Analytical solution for nonlinear Schrödinger vortex reconnection

Analysis of the nonlinear Schrödinger vortex reconnection is given in terms of coordinate-time power series. The lowest order terms in these series correspond to a solution of the linear Schrödinger equation and provide several interesting properties of the reconnection process, in particular the nonsingular character of reconnections, the anti-parallel configuration of vortex filaments and a s...
