The Tehran metropolitan area is extremely vulnerable to earthquakes due the location of its active faults and dense population. Assessing probable damage a high magnitude earthquake on buildings facilities relies precise structural survey, which has an empirical basis depending historic ground motions. probability failure in discrete limits based different motions estimated by fragility curves....

the main goal of the present study was to implement a hybrid pattern of cellular automata model and particle swarm optimization algorithm based on tm and etm+ imagery of landsat satellite from 1988 to 2010 for simulating the urban sprawling. in this study, an alternative model was implemented in two ways: the first method was based on two images (1988 and 2010) and the second one was based on t...

BACKGROUND There are no population-based data available for cancer in Tehran, a city that includes almost 10% of the Iranian population. This is the first report of cancer incidence in Tehran from a population-based cancer registry for the period of 1998-2001. METHODS The cancer registry collects data on all new cases of cancer diagnosed in the resident population of Tehran metropolitan area....
