A Mathematical Programing Model of Budget Allocation for Development Disparities Reduction among Iran Provinces

The issues of disparities, regional imbalance development and attempt to reducing development disparities among various regions have been attracted considerable attention among researchers, planners and policy makers. In this regard, this study employs a mathematical programing model for budget resources allocation among Iran provinces in order to development disparities reduction among them. I...

Transport Equation Reduction for a Mathematical Model in Plant Growth

In this article a variational reduction method, how to handle the case of heterogenous domains for the Transport equation, is presented. This method allows to get rid of the restrictions on the size of time steps due to the thin parts of the domain. In the thin part of the domain, only a differential problem, with respect to the space variable, is to be approximated numerically. Numerical resul...

A Mathematical Model for Flood Protection

Many regions in the world are protected against flooding by a dike, which may be either natural or artificial. We deal with a model for finding the optimal heights of such a dike in the future. It minimizes the sum of the investments costs for upgrading the dike in the future and the expected costs due to flooding. The model is highly nonlinear, nonconvex, and infinite-dimensional. Despite this...

A New Mathematical Model for Permeability of Composites

Study of permeability of Fibrous Composites is important in several natural and industrial processes in mechanical engineering. In this study, a comprehensive mathematical model is presented for calculation of normal permeability of ordered elliptical fibrous media. An innovative scale-analysis technique is employed for determining the normal permeability of elliptical fibrous media. In this te...
