Methods of extrapolating the t-expansion series.
نویسنده
چکیده
We present four new methods in addition to the standard methods of extrapolating the t-expansion series, and make a comprehensive comparison of these procedures by applying them to the t-series for three quantum systems. We have found that by writing the series as a ratio of decreasing exponentials it is possible to devise methods that are significantly more accurate than the standard methods for low order series. By studying the function t(E) we have found a procedure that is more accurate than the standard methods for all t-series orders in two of the test sytems.

External and Internal Incompressible Viscous Flows Computation using Taylor Series Expansion and Least Square based Lattice Boltzmann Method
The lattice Boltzmann method (LBM) has recently become an alternative and promising computational fluid dynamics approach for simulating complex fluid flows. Despite its enormous success in many practical applications, the standard LBM is restricted to the lattice uniformity in the physical space. This is the main drawback of the standard LBM for flow problems with complex geometry. Several app...

متن کاملDamage identification of structures using second-order approximation of Neumann series expansion
In this paper, a novel approach proposed for structural damage detection from limited number of sensors using extreme learning machine (ELM). As the number of sensors used to measure modal data is normally limited and usually are less than the number of DOFs in the finite element model, the model reduction approach should be used to match with incomplete measured mode shapes. The second-order a...

متن کاملApproximate solution of the stochastic Volterra integral equations via expansion method
In this paper, we present an efficient method for determining the solution of the stochastic second kind Volterra integral equations (SVIE) by using the Taylor expansion method. This method transforms the SVIE to a linear stochastic ordinary differential equation which needs specified boundary conditions. For determining boundary conditions, we use the integration technique. This technique give...
