Many empirical methods for estimating LSTR have been introduced by scientists during the recent decades, but these methods have been calibrated and applied under limited conditions of bed profile and specific range of bed sediment size. The existing empirical relations are linear or exponential regressions based on the observation and measurements data and there’s a great potential to build mor...
This paper based on the new empirical industrial organization model (NEIO) examines the impact of market concentration and cost efficiency on bank's profit rate margin in Iran. The study uses the model developed by Azzam (1997) to evaluate the market power and cost efficiency for 15 active banks in the banking industry. The empirical findings indicate a decrease in the market power of banks dur...
The aim of this paper is determination of an optimal policy rule for Iranian economy from an Islamic perspective. This study draws on an Islamic instrument known as the Musharakah contract to design a dynamic stochastic general equilibrium model. In this model the interest rate is no longer considered as a monetary policy instrument and the focus is on the impact of economic shocks on the Dynam...
the need for more comparisons among models is widely recognized. this study aimed to compare three different modelling approaches for their capability to simulate and predict trends and patterns of winter wheat yield in western germany. the three modelling approaches included an empirical model, a process-based model (lintul2), and a metamodel derived from the process-based model. the models ou...
Within the framework of the European MFSTEP project, an advanced multivariate sequential data assimilation system has been implemented to assimilate real chlorophyll data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) into a threedimensional biochemical model of the Eastern Mediterranean. The physical ocean 5 is described through the Princeton Ocean Model (POM) while the biochemistry ...
In this paper we propose a simulation study to carry out dynamic analysis of CNTFET-based digital circuit, introducing in the semi-empirical compact model for CNTFETs, already proposed by us, both the quantum capacitance effects and the sub-threshold currents. To verify the validity of the obtained results, a comparison with Wong model was carried out. Our mode...
