Staggered-grid finite-difference (SGFD) schemes have been used widely in seismic modeling. The spatial difference coefficients of the SGFD scheme are generally determined by a Taylor-series expansion (TE) method or optimization methods. However, high accuracy is hardly guaranteed both at small and large wavenumbers by using these conventional methods ...

Abstract Relativistic and non-relativistic Hartree-Fock calculations have been carried out for the series CH4 to PbH4 within the spherically symmetric one-centre expansion approximation. Inaccuracies are found in earlier work by Mackrodt using the same model. The calculated bond lengths agree with experiment within a few per cent.

42nd Midwest Symposium on Circuits and Systems (Cat. No.99CH36356), 2003
It is shown that the locations and amplitudes of the extrema of the sin x/x function, when expressed under the form of series expansions, can be calculated very fast through a straightforward recursion formula. Moreover, very simple accurate algebraic expressions are given for these locations and amplitudes.

Performance Evaluation, 1999
Abstract Recently, a Taylor series expansion was developed for expected stationary waiting times in open (max,+)-linear stochastic systems with Poisson input process; these systems cover various instances of queueing networks. As an application, we present an algorithm for calculating the coefficients for infinite capacity tandem queueing networks ...

Publisher Summary This chapter presents the utilization of Pade approximants as tools for summing several divergent series that arise in the theory of diffusion of fluid particles by a random or turbulent velocity field. The turbulent diffusion can be described by a perturbation expansion with a diagram structure very similar to that of some quantum ...
