A new algorithm for solving onedimensional Schrödinger equations in the reproducing kernel space
(Springer, 20131201)On the basis of a reproducing kernel space, an iterative algorithm for solving the onedimensional linear and nonlinear Schrödinger equations is presented. The analytical solution is shown in a series form in the reproducing ...

Approximations in (bi)hyperideals of Semihypergroups
(Springer, 20131201)We consider the fundamental relation on a semihypergroup to interpret the lower and upper approximations as subsets of the fundamental semigroup and we give some results in this connection. Also, we introduce the notion ...

ODCharacterization of some orthogonal groups
(Springer, 20131201)In this paper, it was shown that , where and , and , where is not prime and , are ODcharacterizable.

A novel hybrid spectralvariational iteration method (HSVIM) for solving nonlinear equations arising in heat transfer
(Springer, 20131201)The purpose of this study is to implement a new modification of the variational iteration method (HSVIM), which is a combination of spectral method and variational iteration method for heat transfer problems with high ...

Toepad morphology in White's tree frog, Litoria caerulea (Family Hylidae)
(Springer, 20131201)The aim of this study was to find any structural differences between the digital pads of forelimbs and hind limbs as well as more careful investigation of the internal and external structures of the toepad. In this study, ...

The generalization of structure factor for rods by polygon section in twodimensional phononic crystals
(Springer, 20131201)The purpose of this paper is the generalization of structure factor for rods by polygon section in two dimensional phononic crystals. If we use the plane wave expansion method (PWE) for the propagation of acoustic waves ...

Theoretical Calculation of Energies of Projectile like Fragments in 76Ge (635 MeV) + 198Pt DeepInelastic Collisions
(Springer, 20131201)The theoretical calculation of the energies of projectile like fragments (PLFs) using the heavyion reactions between 76Ge and 198Pt are reported in this article. The incident beam energy was 635 MeV. The calculated values ...

Theoretical studies of the optical spectra and EPR parameters for VO2+ ions in Zn(antipyrine)2(NO3)2
(Springer, 20131201)The optical spectrum band positions and EPR parameters (g factors g//, g^ and hyperfine structure constants A// and A^) for VO2+ ions in Zn(antipyrine)2(NO3)2 are theoretically studied from the complete diagonalization (of ...

Global analysis of a delay SVEIR epidemiological model
(Springer, 20131201)This paper is concerned with global analysis of a delay SVEIR epidemiological model in a population of varying size. By using Lyapunov stability method and LaSalle's invariance principle for delay systems, we prove that ...

Numerical study of some nonlinear wave equations via Chebyshev collocation method
(Springer, 20131201)The numerical methods are of great importance for approximating the solutions of nonlinear ordinary or partial differential equations, especially when the nonlinear differential equation under consideration faces difficulties ...

Strain analysis of the Darvazeh Quran fault, Zagros Mountains, Iran
(Springer, 20131201)The Zagros FoldandThrust Belt is tectonically active and often has active faults with insensible and slow motions. Determining the rate of movement and displacement in these faults requires very precise measurements. One ...

On the multiplication operator on analytic function spaces
(Springer, 20131201)Let be a Hilbert space of functions analytic on a plane domain such that for every in the functional of evaluation at is bounded. Assume further that contains the constants and admits multiplication by the independent ...

First record of Anaciaeshna jaspidea and Epophthalmia vittata vittata (Odonata: Anisoptera) from Pakistan
(Springer, 20131201)During a survey of Sindh and Punjab provinces of Pakistan, two dragonfly genera were collected and identified for the first time from the country. Anaciaeshna(Family Aeshnidae) is a genus of large dragonflies. Representatives ...

The operational matrix of fractional integration for shifted Legendre polynomials
(Springer, 20131201)In this article we implement an operational matrix of fractional integration for Legendre polynomials. We proposed an algorithm to obtain an approximation solution for fractional differential equations, described in ...
