Short Note An Improved Method to Extract Very-Broadband Empirical Green’s Functions from Ambient Seismic Noise
The extraction of Green’s functions by cross correlation of continuous seismic records at station pairs is best achieved in a diffuse wave field, where energies radiated by random sources have equal power. To partially satisfy the diffuse wave-field condition, original seismic records must be normalized as they are highly nonstationary and may have amplitude variations of orders of magnitude wi...
متن کاملAn Improved Modified Extended tanh-Function Method
In this paper we further improve the modified extended tanh-function method to obtain new exact solutions for nonlinear partial differential equations. Numerical applications of the proposed method are verified by solving the improved Boussinesq equation and the system of variant Boussinesq equations. The new exact solutions for these equations include Jacobi elliptic doubly periodic type, Weie...
متن کاملAn integrated method to valuate the function of green roofs in absorbing air pollutants; Case study: Tehran
Tehran is the capital city of Iran and its inhabitants are suffering from air pollution.Green roofs can be one of the choices to deal with this problem. In this paper, ability ofgreen roofs in absorbing four air pollutants (PM10, SO2, NO2, and CO2) in Tehran wasvaluated. First, the potential of 1 m2 of a hypothetical green roof in Tehran in absorbingPM10 and SO2 during 1 year was estimated usin...
متن کاملRupture characteristics of the 2012 earthquake doublet in Ahar-Varzagan region using the Empirical Green Function method
On August 11, 2012,within several minutes, two shallow destructive earthquakes with moment magnitudes of 6.5 and 6.4 occurred in Varzagan, Azerbaijan-e-Sharghi Province, in the northwest of Iran In this study, the Empirical Green Function (EGF) method was used for strong ground motion simulationto estimate the source parameters and rupture characteristics of the earthquakes. To simulate the fir...
متن کاملAn Empirical Analysis of China’s International Reserves Demand Function
The study aims to estimate an international reserves demand model for China using economic growth, propensity to import, real effective exchange rate and trade openness variables for quarterly period spanning from 1985Q1 to 2014Q4.The bounds testing technique to cointegration is used to test for a long run relationship, while the autoregressive distributed lag approach is used to estimate short...
