the aim of this paper is to investigate the existence of the new non-ricardian regime policy in iranian economy. we detected signs of the non-ricardian regime from quarterly data of 1369 to 1391. to investigate further a dynamic stochastic general equilibrium model is designed to estimate the fiscal and monetary parameters using a bayesian approach. our results indicated a passive monetary poli...

BACKGROUND An increase in the knee adduction moment is one of the risk factors of medial knee osteoarthritis. This study examined the relationship between knee adduction moment and self-reported pain and disability. We also investigated the influence of pain on the relationships between knee adduction moment and gait performance and disability. METHODS Thirty-eight Japanese women with medial ...

In every image processing algorithm quality of image plays a very vital role because the output of the algorithm depends on the quality of input image. Hence, several techniques are used for image quality enhancement and image restoration. Some of them are common techniques applied to all the images without having prior knowledge of noise and are called image enhancement algorithms. Some of the...

A new two-step fuzzy filter that adopts a fuzzy logic approach for the enhancement of images corrupted with impulse noise is presented in this paper. The filtering method (entitled as Fuzzy Random Impulse Noise Reduction method (FRINR)) consists of a fuzzy detection mechanism and a fuzzy filtering method to remove (random-valued) impulse noise from corrupted images. Based on the criteria of pea...

Inhibition from neighboring eccentric cells has an effect on the variability of firing of a given eccentric cell. The reduction in the average impulse rate which is caused by inhibition decreases the variance of the impulse rate. However, this reduction of the average rate increases the coefficient of variation of the impulse rate. Inhibitory synaptic noise should add to the low frequency porti...

In this contribution we examine certain variance properties of model reduction. The focus is on L2 model reduction, but some general results are also presented. These general results can be used to analyze various other model reduction schemes. The models we study are nite impulse respons (FIR) and output error (OE) models. We compare the variance of two estimated models. The rst one is estimat...

We propose a blind dereverberation method based on spectral subtraction using a multi-channel least mean squares (MCLMS) algorithm for distant-talking speech recognition. In a distant-talking environment, the channel impulse response is longer than the short-term spectral analysis window. By treating the late reverberation as additive noise, a noise reduction technique based on spectral subtrac...

background: the purpose of this study was to calculate and compare the specificity and sensitivity of impulse oscillometry (ios) as a new technique in the detection of airways dysfunction by means of a simple pulmonary function test in chemical warfare injured cases suffering from respiratory diseases.   methods: the study was performed prospectively in 100 patients, who complained of dyspnea a...

abstract different strategies are existed for adjusting with water shortage, of which the strategy of suitable policies adoption by determining optimum production function can be mentioned. water shortage and quality degradation of soil and water resources is one of main factors of production reduction. therefore, this study was carried out for determination of tomato sensitivity coefficients a...
