In a concise introduction to nonlocal continuum models and their mathematical foundation and numerical discretization, Du focuses particularly on nonlocal systems with a finite range of interactions in order to draw close connections with traditional local systems represented by partial differential equations.
In the present paper, the explicit finite-difference scheme with this discretization is verified in the 1D case on several versions of the Riemann problem on the disintegration of a discontinuity, both well-known in the literature [12,15] and new.
As the hand is unable to discriminate vibration stimuli of all frequencies, the vibration stimulus is discretization according to the result of the vibration discriminability experiment.
Taking into account many unresolved issues associated with wind energy, the results of the analysis and evaluation of discretization behaviors in the SMC systems are essential for their applications in the control of renewable energies [19].
Fully discrete schemes for parabolic initial-boundary value problems (IBVP) are usually derived by discretizing either first in space by means of some spatial discretization method like the finite element method and then in time by some time-stepping method or vice versa.
In the deterministic transport calculation, a large part of errors stem from the numerical discretization of all its variables; therefore it is important to develop an approximate measure of these discretization errors.
For example, priori error estimates for finite element discretization of optimal control problems governed by elliptic equations are discussed in many publications.
We begin with an oriented survey of selected problems in discretization of G-gauge theories, where G is a Lie group, and a selection of features in evaluation of inconsistency in pairwise comparisons with coefficients in [R.sup.*.sub.+].
This method benefits from the analyticity of the Laplace transform and efficient numerical inversion of this transform, an accurate discretization approach through Chebyshev collocation, and a convergent linearization technique, which results in a robust method for solving nonlinear time-fractional partial differential equations on a bounded domain.
In recent decades, fractional calculus has found a large number of profound applications, which have triggered the development of both the theory and methods for more reliable discretization and approximations of the dynamics of continuous systems.
We used two essential approaches for performing the discretization, and each of these operates one column (or chemical) at a time.
