In this paper, a new implicit nonstandard finite difference scheme for conservation laws, which preserving the property of TVD (total variation diminishing) of the solution, is proposed. This scheme is derived by using nonlocal approximation for nonlinear terms of partial differential equation. Schemes preserving the essential physical property of TVD are of great importance in practice. Such s...

This paper aims to present an experimental and numerical study on the effect of wetting-drying cycles and plasticity index on the California Bearing Ratio (CBR) of lime stabilized clayey soils. The numerical analysis was carried out based on finite element method for comparison between results of experimental and numerical studies. Three clays with different plasticity indices were mixed with v...

Although today’s Internet predominantly uses the flat-fee pricing scheme, the need for more sophisticated pricing has grown, especially for domains where bandwidth resources are scarce and expensive. This paper focuses on how to determine the price vector that maximizes the system revenue in priority-based networks. Similar problems have been examined using equilibrium analysis, but the assumpt...

Recently, price contract models between suppliers and retailers, with stochastic demand have been analyzed based on well-known newsvendor problems. In Bernstein and Federgruen [6], they have analyzed a contract model with single supplier and multiples retailers and price dependent demand, where retailers compete on retail prices. Each retailer decides a number of products he procures from the s...

Abstract---We present a nodal integral method for the one-dimensional convection-diffusion equation. The development is carried out in the nodal spirit, and results in a method that is second order both in space and time variables. Extension of this method, which is characterized by inherent upwinding, to multi-dimensional problems is straightforward. The nodal method’s ability to yield accurat...

Study of consumer psychology and consumer price index usually used questionnaire method; this method is very good at solving the macro problem, however, to specific numerical value index, used questionnaire method is difficult to determine, and there is always a certain doubt about the correctness of the results what used questionnaire method. Because of EEG can be true reflection of the true p...

In the past decade, the programming languages C++, FORTRAN 90 and Oberon-2 allevolved from their ancestors. This invites to reflect upon the suitability ofthese modern programming languages for scientific and engineering computing. Inthe first part, we compare their primary language features, as needed byscientists and engineers. In the second part, we list some useful featuresmissing in Oberon...
