Dynamics of the Inflationary Era
We live in a very large, very old, and nearly (perhaps exactly) spatially flat universe. The universe we observe is, at least on large scales, remarkably homogeneous and isotropic. These attributes of our universe can be ascribed to a period of very rapid expansion, or inflation, at some time during the very early history of the universe [1]. A sufficiently long epoch of primordial inflation le...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Transport equations for the inflationary spectral index
The imminent arrival of precise microwave background data from Planck makes this a promising time to put constraints on cosmological models, and in particular the inflationary paradigm. To do so, we need accurate calculations of the observables produced by an inflationary phase, of which we expect the spectral index of the density perturbation, ns, to be among the most precisely measured. Planc...
متن کاملAn Analysis of the Inflationary Effect of Subsidies Targeting Scheme of Iran: Flow-of-Funds Approach
At the beginning of 2011, the Islamic Republic of Iran underwent a Scheme called “Subsidies Targeting”. This scheme meant to replace subsidies on goods and services especially energy, which had kept prices low for decades, with a monthly refund to every resident as a compensation plan. Considering the magnitude of price change up to ten times and the important role of Energy carriers in product...
متن کاملNon-Linear Inflationary Dynamics based on the Concept of Missing Money in Iran
In this research, non-linear inflationary dynamics based on the concept of missing money is studied using the threshold autoregressive models based on seasonal data of the time interval (1990:04-2016:07) for the economy of Iran. The finding of the research shows that simple and Divisia liquidity growth variables are determined as threshold variables, and inflation reacts to changes in the growt...
