In this paper, a novel computational technique for finite discrete approximation of continuous dynamical systems suitable for a significant class of biochemical dynamical systems is introduced. The method is parameterized in order to affect the imposed level of approximation provided that with increasing parameter value the approximation converges to the original continuous system. By employing...

In this project, we address a general technique for constructing an ε-approximation algorithm out of a so-called pseudo approximation algorithm. We then show how this technique can be applied to the problem of finding the Lp-shortest path above a polyhedral terrain. Our results includes a new approximation algorithm that for any p ≥ 1, computes a (2(1− 1 p ) + ε)-factor approximation of the Lp-...

Recursive approximation of the set of feasible parameters is a key problem in set membership identification. In this paper a new technique is presented, aimed at recursively computing an outer orthotopic approximation of polytopic feasible parameter sets. The main idea is to exploit the concept of binding constraints in linear programs, in order to select a limited number of constraints providi...

Integral and integro-differential equations are one of the most useful mathematical tools in both pure and applied mathematics. In this article, we present a variational iteration method for solving Fredholm integro-differential equations. This study provides an analytical approximation to determine the behavior of the solution. To show the efficiency of the present method for our proble...

Ranking of companies listed on the exchange represent their status and considered a criterion for investment. Also, it increases market's competition, development and efficiency. In this study, the fifty superior companies listed in Tehran Stock Exchange were ranked based on financial ratios (liquidity, operational, leverage and profitability) using FAHP- FTOPSIS hybrid approach during the year...
