The paper examines the possibility of using an alternative approach to predicting statistical indicators a new COVID-19 virus type epidemic. A systematic review models for epidemics infections in foreign and Russian literature is presented. accuracy SIR model spring 2020 wave epidemic forecast Russia analyzed. As modeling spread model, CIR discrete stochastic proposed based on balance at curren...

a new model based on a combination of the polymeric multigrain and multilayer models has been developed to predict the polymerization rate, particle growth, morphology, effective parameters on broadening of the molecular weight distribution, number and weight average of the molecular weight, isotacticity index and bulk density of polymer. mathematical correlations and the kinetics used in this ...

The purpose of the present research is to investigate the effective channels of the monetary transmission mechanism in Iran. To do so, we devised a New Keynesian Dynamic Stochastic General Equilibrium Model. In our model, the different types of nominal rigidities are introduced beside all the related structural equations, which are extracted and linearized around a steady state point. Furthermo...

in this paper, based on a new keynesian structure, we have analyzed monetary policy response to exchange rate volatilities in iran. for this purpose, first, exchange rate derived from equilibrium condition in exchange market and then two different models have been estimated. assumption on the first model is that central bank responses to exchange rate volatilities and the assumption on the seco...
