according to amount of oil seeds import in iran are more than 80% of domestic needs, in this study, import comparative advantage in soybeans using rca and rsca index is calculated in 1961-2008 periods for iran and ten important importer countries. iran’s competition state is investigated. also long run relation between production and import comparative advantage index is estimated using johanse...

The higher integration technologies made it possible for accessing any device so fast that within a fraction of seconds the job can be performed. Now days fast memories exists everywhere during accessing if any error happens that has to be detected and corrected within a fraction of microseconds that is made possible with help high performance error correcting codes(ECCs) such as LDPC and Turbo...

In many high speed Digital Signal Processing (DSP) and multimedia applications, the multiplier plays a very important role because it dominates the chip power consumption and operation speed. In DSP applications, in order to avoid infinite growth of multiplication bit width, it is necessary to reduce the number of multiplication products. Cutting off n-bit Less Significant Bit (LSB) output can ...

one of the import indices of food security evaluation is food import capacity index. ratio of total exports to food imports is often thought to be a measure of the capacity of a country to finance its food imports using revenues from exports of goods and services. this study investigates food import capacity effects on rural households food security by calculated ahfci (aggregate household food...

iran is one of the most concentrated areas of afghan migrants and refugees. most afghans dispersed throughout the country mixed with iranian households. the majority of afghan immigrants are typically unskilled and illegal workers. this study aims at investigating the nature of the causal relationship between afghan immigrants and two main labor market indicators, average wages and unemployment...

this study uses vector error correction model to examine the effects of oilseeds, crude oil and vegetable oil tariffs on vegetable oil consumer price. monthly data sets for the years 2004-2013 and var and vecm models were applied for this study. research findings indicates only a long term equilibrium relation between the study variables .the effect of vegetable oil tariffs on consumer and prod...

abstract main objective of this paper is to investigate the impact of exchange rate misalignment on wheat’s producer estimates (pse), using the 1989-2007 period’s data. for this purpose, vector error correction model (vecm) along with the use of real exchange rate based on purchasing power party (ppp) was applied to estimate nominal equilibrium exchange rates. then, by using market price suppor...

Many areas of applied statistics have become aware of the problem of measurement error-prone variables and their appropriate analysis. Simply ignoring the error in the analysis usually leads to biased estimates, like e.g. in the regression with error-prone covariates. While this problem has been discussed at length for parametric regression, only few methods exist to handle nonparametric regres...
