in this article, an analytical solution is developed to study the free vibration analysis offunctionally graded rectangular nanoplates. the governing equations of motion are derived basedon second order shear deformation theory using nonlocal elasticity theory. it is assumed that thematerial properties of nanoplate vary through the thickness according to the power lawdistribution. our numerical...

tetrazole-containing compounds have been the subject of much recent research because of theirpotential as high energy density materials (hedms). in this work, theoretical studies on the 1htetrazolylderivatives of tetrahedrane were done at the density functional theory (dft) method withthe 6-31g(d) basis set without any symmetrical restrictions in order to find the structural andenergetically pr...

In Reference [1], we studied the improvement of the Wilson-Dirac theory by removing all lattice artifacts linear in the lattice spacing a in on-shell matrix elements. In general, such an improvement for the dimension 3 fermion bilinear operators requires one to tune the coefficient of the clover operator in the action, determine the coefficient of an extra term each in the vector, axialvector, ...

In this paper, an improved seventh-order WENO (WENO-Z7) scheme is suggested by extending the 5th-order WENO scheme of Borges et al[R. Borges, M. Carmona, B. Costa, W. S. Don, An improved weighted essentially non-oscillatory scheme for hyperbolic conservation laws, J. Comput. Phys. 227(2008) 3191-3211]. The sufficient condition for seventh-order accuracy is described for the new smoothness indic...
