introduction temporal and spatial change of meteorological and environmental variables is very important. these changes can be predicted by numerical prediction models over time and in different locations and can be provided as spatial zoning maps with interpolation methods such as geostatistics (16, 6). but these maps are comparable to each other as visual, qualitative and univariate for a lim...

We model cheating in second price auctions when valuations of bidders are affiliated. Bidders predict cheating behavior by an unfair seller who can observe the bids submitted by all bidders and then submits his extra bid to increase the payment of the winning bidder. We derive a symmetric equilibrium strategy in the cheating model. Moreover, we conduct a numerical analysis to compare a second p...

We provide two approaches to the numerical analysis of stochastic control problems. These analyses rely on linear programming formulations of the control problem and allow numerical comparison between controls and numerical veriication of optimality. The formulations characterize the processes through the moments of the induced occupation measures. We deal directly with the processes rather tha...

in this paper, one of the numerical solution method of one- particle, one dimensional timeindependentschrodinger equation are presented that allows one to obtain accurate bound state eigenvalues and functions for an arbitrary potential energy function v(x).for each case, we draw eigen functions versus the related reduced variable for the correspondingenergies. the paper ended with a comparison ...

In this investigation, attempts have been made to solve two-dimension nonlinear viscous flow between slowly expanding or contracting walls with weak permeability by utilizing a semi analytical Akbari Ganji's Method (AGM). As regard to previous papers, solving of nonlinear equations is difficult and the results are not accurate. This new approach is emerged after comparing the achieved solutions...

in this paper, the two-dimensional triangular orthogonal functions (2d-tfs) are applied for solving a class of nonlinear two-dimensional volterra integral equations. 2d-tfs method transforms these integral equations into a system of linear algebraic equations. the high accuracy of this method is verified through a numerical example and comparison of the results with the other numerical methods.

we show how daubechies wavelets are used to solve kuramoto-sivashinsky type equations with periodic boundary condition‎. ‎wavelet bases are used for numerical solution of the kuramoto-sivashinsky type equations by galerkin method‎. ‎the numerical results in comparison with the exact solution prove the efficiency and accuracy of our method‎.

This study develops an optimal pricing and replenishment policy in an arborescent (tree-like) supply chain system. Since it benefits the up-streams more than the down-streams when a producer, a distributor and multiple retailers are integrated, a pricing strategy with price reduction is derived to entice the down-streams to accept the incentive system with minimum total cost. Negotiation factor...

in this article, we study the analytical solutions of different parabolic heat equations with different boundaryconditions in the form of multi-term fractional differential equations. then we compare these analytical solutions with numerical finite difference methods. this comparison demonstrates the accuracy of the analytical and numerical methods presented here.
