In this study, a model of Bayesian Dynamic Stochastic General Equilibrium (DSGE) from Real Business Cycles (RBC) approach with the aim of identifying the factors shaping price bubbles of Tehran Stock Exchange (TSE) was specified. The above-mentioned model was conducted in two scenarios. In the first scenario, the baseline model with sentiment shock was examined. In this model, stock price bubbl...

In this paper we investigate the effect of oil price shocks on stock market index in Iran, by using of a structural VAR (SVAR) approach. We used four variables in the model namely Kilian index, global oil supply, real oil price and real stock market index. The data are monthly and spanning the period 1997M10-2014M12. We identify the effect of four different shocks on stock market including oil ...

Context: Food safety is essential for every human. It determines public health, nutrition, elimination of hunger, and the promotion sustainable agriculture. crucial production, consumption, international food trade. Ensuring fundamental challenge 21st century. often related to defense includes protection against intentional contamination with various chemical, biological, or other harmful subst...

With the development of hypersonic air-breathing propulsion systems, such as supersonic combustion ramjet (Scramjet) and rocket-based combined cycle (RBCC) engines, mixing process airstream with fuel in engine combustor has been drawing more attention. Due to compressibility effects, a condition is significantly inhibited. In present paper, novel strategy wall-jet induced shock waves (WJISW) pu...

A multi-state reliability analysis model suffering from a dependent competing failure process is developed in this study, where the soft described by general nonlinearity random effect. Wiener degradation with measurement error and hard caused shock. Considering that shock not only may cause abrupt damage but also can accelerate degradation, there are some correlations between failure. Based on...

The acceleration mechanism at ultrarelativistic shocks is investigated using the Monte Carlo simulations. We apply a method of discrete small amplitude particle momentum scattering to reproduce highly anisotropic conditions at the shock and carefully describe the acceleration mechanism. The obtained acceleration times equal 1.0 rg/c if the spectral index reach the value of 2.2, independent of p...

We consider a recently developed conservative shock filter model in order to postprocess numerical solutions of the 1-D Euler equations of gas dynamics. The shock filtering process involves the definition of an indicator selecting the data regime where the filter is applied. Illustrated by several classical numerical test problems, we show that the use of simple indicators based on physical pri...
