the determination of temporal and spatial salinity in tidal rivers is significant in supplying water for agriculture purposes, particularly where there is no controller dam at the downstream. in this research, the coherens model was applied to study the hydraulics of water flow, salinity distribution and transmission at the bahmanshir river. coherens is a 3d multi-purpose hydrodynamic model whi...
human capital has important role on economic growth. this factor can increase labor and capital productivity. it can increase capacity of new technology and reduce criminal participation and improve voters’ political behavior and migration of people with high human capital to another region has effects on region and spatial spillover on other regions. the present study aimed to analyze the dire...
In recent years, the studies of location play a key role in success and stability of economic activities. Location studies are under consideration in both national and international levels. Meanwhile, identification of goals and methods of solving location problems have significant importance. The purpose of this paper is to examine spatial distribution of economic activities in 14 zones of Esf...
the rapid change of land use and land cover in the metropolitan area of tehran has influenced the distribution pattern of land surface temperature (lst). in this study, a spatial autocorrelation analysis is adopted to process the spatial-temporal changes of lst and normalized difference vegetation index (ndvi) in tehran during the period of 1987 to 2010. global spatial autocorrelation analysis ...
Background: The hippocampus, a vital center for learning and memory, is extremely vulnerable to neurological diseases.Several reports of cognitive and memory impairment have been published in patients with Multiple sclerosis (MS). The prevalence of MS is highest where environmental supply of vitamin D is low. In the present study spatial working memory and reference memory after treatment with ...
Abstract Over the last few decades, different mathematical methods have been used to design and analyze architectural spaces. Meanwhile, the graph theory provides an abstract model to study the spatial configuration, so that a simple and flexible mathematical framework is obtained to analyze the spatial topological features and their relationship with social and functional concepts in architec...
The aim of this study was to evaluate the spatial distribution of soil infiltration using geostatistics methods in a regional scale on 400 hectares of Mansour Abad Plain, in Larestan region, Fars Province. Sampling and parameters measurement were done for 78 points in a regular grid with a distance of 100*100 meters; for these variables, the best variogram model between linear, exponential, Gau...

Urban growth is a dynamic and evolutionary spatial and social process that relates to the changes of urban spatial units and the transformation of people’s lifestyles and consequently demographic changes. Considering the urban development process as a function of land uses interactions, population structure and the strategic behavior of the agents involved in the urban development process (the ...
