the objective of this study is to measure the city of tehran’s environmental quality in 2006 (the last census year). primarily, with a comparative analysis of a variety of urban sustainability indicator models, a collection of 54 indicators have been chosen and categorized as indicators of increase or decrease in urban environmental quality in the form of a simple mathematical model. based o...
Creative city is a house for art creativities, scientific and technological innovations and clear voice of developing cultures; the city which fulfills all its creative potentials and is the pioneer of cultural and developmental activities. Qazvin is among the prone cities that doesn’t have a far distance to its prosperity of creativity. Therefore, this research tries to analyze the indicators ...
Rapid urban land expansion and the resulting arable land loss have put food security in China at risk. This paper investigates the characteristics and mechanism of arable land conversion in Beijing using a logistic model based on land-use data for 2001 and 2010. The results suggest that (1) arable land conversion tends to occur near built-up areas, city centers and major roads; (2) arable land ...
This paper attempts to predict heavy metals (Pb, Zn and Cu) in the groundwater from Arak city, using support vector regression model(SVR) by taking major elements (HCO3, SO4) in the groundwater from Arak city. 150 data samples and several models were trained and tested using collected data to determine the optimum model in which each model involved two inputs and three outputs. This SVR model f...
