Pollutant dispersion diagnosis over complex surfaces of variable land use using unstructured prismatic grid

Adaptive hierarchical grid model of water-borne pollutant dispersion

Water pollution by industrial and agricultural waste is an increasingly major public health issue. It is therefore important for water engineers and managers to be able to predict accurately the local behaviour of water-borne pollutants. This paper describes the novel and ecient coupling of dynamically adaptive hierarchical grids with standard solvers of the advection±di€usion equation. Adapti...

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Multi-Scale Modelling of Population and Land Use with a Variable Grid CA

Aerodynamic Shape Optimization Using Unstructured Grid Methods

Two unstructured-grid Euler-based CFD codes, AIRPLANE and FLOWCART were coupled to a gradientbased quasi-Newton finite-difference optimization algorithm. These two optimization techniques were developed to provide detailed aerodynamic shape optimization methods for complete configurations with efficient grid generation methods. AIRPLANE utilizes a tetrahedral mesh whereas FLOWCART uses a hexahe...

Analysis of Changes of Land use/Cover by using SWOT Matrix for Compling Solution for Land Use Sustainable Management of land use in Taleghan, Iran

  Substantial population growth and urbanization arbitrarily banning the exploitation of natural resources and environmental factors adversely impacts the environment and resources necessary for nutrition and healthy life styles. The secret to success and survival of ecosystems depends on a stable, continuous monitoring of the environment. The SWOT model has been developedto consider all int...
