Time-dependent creep analysis is crucial for the performance and reliability of piezoactuators used for high-precision positioning and load-bearing applications. In this study history of stresses, deformations and electric potential of hollow rotating cylinders made of functionally graded piezoelectric material (FGPM), e.g., PZT_7A have been investigated using Mendelson’s method of successive e...

in this paper, a technique generally known as meshless numerical scheme for solving fractional dierential equations isconsidered. we approximate the exact solution by use of radial basis function(rbf) collocation method. this techniqueplays an important role to reduce a fractional dierential equation to a system of equations. the numerical results demonstrate the accuracy and ability of this me...

We prove global well-posedness for the radial defocusing cubic wave equation

In this article, we apply the Multiquadric radial basis function (RBF) interpo-lation method for nding the numerical approximation of traveling wave solu-tions of the Kawahara equation. The scheme is based on the Crank-Nicolsonformulation for space derivative. The performance of the method is shown innumerical examples.

In this paper, some meshless methods based on the local Newton basis functions are used to solve some time dependent partial differential equations. For stability reasons, used variably scaled radial kernels for constructing Newton basis functions. In continuation, with considering presented basis functions as trial functions, approximated solution functions in the event of spatial variable wit...

We investigate radial oscillations of pure neutron stars and hybrid stars, employing equations state nuclear matter from Brueckner-Hartree-Fock theory, quark the Dyson-Schwinger model, performing a Gibbs construction for mixed phase in stars. calculate eigenfrequencies corresponding oscillation functions. Our results zero points first-order frequencies give maximum mass stable consistent with c...

We consider the focusing inhomogeneous biharmonic nonlinear Schrödinger equation in $$H^2(\mathbb {R}^N)$$ , $$\begin{aligned} iu_t + \Delta ^2 u - |x|^{-b}|u|^{\alpha }u=0, \end{aligned}$$ when $$b > 0$$ and $$N \ge 5$$ . first obtain a small data global result $$H^2$$ which, five-dimensional case, improves previous from Pastor second author. In sequel, we show main result, scattering below ma...

A Hydro+Cascade model has been used to describe radial and elliptic flow at the SPS and successfully predicted the radial and elliptic flow measured by the both STAR and PHENIX collaborations. Furthermore, a combined description of the radial and elliptic flow for different particle species, restricts the Equation of State(EoS) and points towards an EoS with a phase transition to the Quark Gluo...
