This project studies the effects of vehicle routing on pollution levels. We aim to develop queueing theory based mathematical models to analyse highway traffic flows and focus on focus on the capacity drop and shockwaves. Then we intend to use emission models and plume model to predict air pollution in a wider region. These predictions will be tested using remote sensing data and data from meas...

iran  budgeting  structure  and concepts  have  changed  since  200 i .these changes  embrace  the  items  such  as  ,   concepts  of revenues  ,   expenses  , capital   assets   as  well   as   financial   assets   ,    which   resulted    in  more information  transparency .   as a results  the government  budget  is  drawn up  as  such  of an  economic   firm's  budget.  structural  ref...

We consider mathematical models for portfolio credit risk. We analyze the mathematical structure and in particular the modelling of dependence between default events in these models and propose extensions of standard industry models. We study the model risk related to the choice of model structure and input parameters. Finally we develop and test several approaches to model calibration in credi...

In spite of the fact that the principles of impinging stream reactors have been developed for more than half a century, the performance analysis of such devices, from the viewpoint of the mathematical modeling, has not been investigated extensively. In this study two mathematical models were proposed to describe particulate matter drying in tangential impinging stream dryers. The models were de...
