on the basis of a reproducing kernel space, an iterative algorithm for solving the one-dimensional linear and nonlinear schrödinger equations is presented. the analytical solution is shown in a series form in the reproducing kernel space and the approximate solution is constructed by truncating the series. the convergence of the approximate solution to the analytical solution is also proved. th...

for more than three decades healthcare decentralization has been promoted in developing countries as a way of improving the financing and delivery of public healthcare. decision autonomy under healthcare decentralization would determine the role and scope of responsibility of local authorities. jalal mohammed, nicola north, and toni ashton analyze decision autonomy within decentralized services...

A reproducing kernel Hilbert space restricts the space of functions to smooth functions and has structure for function approximation and some aspects in learning theory. In this paper, the solution of an integral equation of the third kind is constructed analytically using a new method. The analytical solution is represented in the form of series in the reproducing kernel space. Some numerical ...

 We study processes in which neutrinos can be generated as a possible source for the neutrion emission form neutron stars. In the high energy limit and in the range em< E< Mw the cross sention for ye→evv  is analytically calculated. We also calculate the cross section for yy→vv  in the noncommutative space. The obtained results in comparison with the cross section for yy→vv  and yy→ yvv  in the...

A simple method for solving Prandtl's integro-differential equation is proposed based on a new reproducing kernel space. Using a transformation and modifying the traditional reproducing kernel method, the singular term is removed and the analytical representation of the exact solution is obtained in the form of series in the new reproducing kernel space. Compared with known investigations, its ...

Love-type wave generation in a fiber-reinforced medium placed over an inhomogeneous orthotropic half-space is analysed. The upper and lower boundary surfaces of the fiber reinforced medium are periodically corrugated. Inhomogeneity of half-space is caused by variable density and variable shear modules. Displacement components for layer and half-space are derived by applying separable variable t...

Changing a space to a place is the existential purpose of architecture. Literature review regards the complex architectural organization as a significant factor for the maximum use of the individualschr('39') performances and activities. Due to exterior spaceschr('39') necessity beside the interior ones, the architect creates a third space; and due to this in-between space, the complexchr('39')...

in this paper, the matsumoto metric with special ricci tensor has been investigated. it is proved that, if  is ofpositive (negative) sectional curvature and f is of  -parallel ricci curvature with constant killing 1-form ,then (m,f) is a riemannian einstein space. in fact, we generalize the riemannian result established by akbar-zadeh.

we study connected orientable spacelike hypersurfaces $x:m^{n}rightarrowm_q^{n+1}(c)$, isometrically immersed into the riemannian or lorentzian space form of curvature $c=-1,0,1$, and index $q=0,1$, satisfying the condition $~l_kx=ax+b$,~ where $l_k$ is the $textit{linearized operator}$ of the $(k+1)$-th mean curvature $h_{k+1}$ of the hypersurface for a fixed integer $0leq k
