BACKGROUND This year's new H1N1 flu strain has rapidly become a serious threat worldwide. This pandemic calls for urgent preparedness to mitigate its impact as much as possible. Employing this knowledge, we simulated a model of the outbreak of H1N1 in two cities of Iran (middle size: Kerman and metropolitan: Tehran). METHODS We developed a compartmental model to predict the expected number of...

Most parts of the urban areas are faced with the problem of floating fine particulate matter. Therefore, it is crucial to estimate the amounts of fine particulate matter concentrations through the urban atmosphere. In this research, an artificial neural network technique was utilized to model the PM2.5 dispersion in Tehran City. Factors which are influencing the predicted value consi...
