# Value problems by using semi analytic method

Numerical solutions have several advantages over analytical solutions. Hussein Abstract The aim of this article is to solve second order Emden—Fowler equations as a type of singular ordinary differential equations. Liu and Wu [ 4 ] give the general differential quadrature rule GDQR for the solution of eighth-order differential equation.

In the present paper, the seventh- eighth- and tenth-order boundary value problems are solved using the homotopy analysis method HAM. For instance, a recipe might refer to cooking vegetables, which is another procedure that in turn requires heating water, and so forth. To reduce undesired numerical reflection from the PML additional back absorbing layers technique can be used. Another joke is that "To understand recursion, you must understand recursion. The running of a procedure involves actually following the rules and performing the steps. A smaller time step would be required to get better agreement between the numerical solution and the analytical solution.

It is also intended for policy-makers in mental health, students of different models of psychotherapy and the psychosocial field. Linearization techniques for singular initial-value problems of ordinary differential equations. The results of the examples are compared with exact solutions when available, also, compared with other methods to assign the effectiveness and accuracy of the suggested method. This can be done by defining it for a simple case in which it combines sentences, and then defining the other cases recursively in terms of the simple one.

FDTD is a time-domain technique, and when a broadband pulse such as a Gaussian pulse is used as the source, then the response of the system over a wide range of frequencies can be obtained with a single simulation. This allows natural hybriding of FDTD with sets of auxiliary differential equations that describe nonlinearities from either the classical or semi-classical standpoint.

It's when you save the query, leave the page, go somewhere else in Peoplesoft, then go back to open Query Manager that it actually shows you that it's doing the character conversion. J Appl Sci ; 7 Dorothy thinks witches are dangerous, in which the sentence witches are dangerous occurs in the larger one. This results in the basic FDTD time-stepping relation that, at any point in space, the updated value of the E-field in time is dependent on the stored value of the E-field and the numerical curl of the local distribution of the H-field in space.

Recursion is related to, but not the same as, a reference within the specification of a procedure to the execution of some other procedure. The simulation evolves the E and H fields forward in time.

The author Rights URI: It has an interactive JAVA type graph that lets one explore the effects of time step variations on the solution. With fast computer speeds available today this is not really an issue for most model equations that one would explore in an introductory geoscience course.

This work presents semi numerical-analytic solutions to linear twelfth-order boundary value problems by applying Differential Transform Method (DTM). The presented method is illustrated with two examples and series solutions are given.

Lie symmetry method is applied to find analytic solutions of initial–boundary-value problems of transient conduction in semi-infinite solid with constant surface temperature or constant heat flux condition.

Boundary value problems arise in many applications, and shooting methods are one approach to approximate the solution of such problems.A Shooting method transforms a boundary value problem into a sequence of initial value problems,and takes the advantage of the speed and adaptivity of initial value problem solvers.

Existing analytic or semi. proposed semi-analytic method involves two steps: ﬁrst we evaluate adisplacement ﬁeld in afull space, then apply acorrection to satisfy the boundary condition (also, see Nguyen et al. ). The aim of this paper is to use the homotopy analysis method (HAM), an approximating technique for solving linear and nonlinear higher order boundary value problems.

Using HAM, approximate solutions of seventh- eighth- and tenth-order boundary value problems are developed. This paper deals with the analytic-numerical solution of random heat problems for the temperature distribution in a semi-infinite bar with different boundary value conditions.
