the iranian poultry sector has experienced many significant structural changes in recent years. such changes may have influenced price dynamics and transmission of shocks through marketing channels especially on retail markets. this paper investigate price transmission, threshold behavior and asymmetric adjustment in poultry sector of ardebil (ar), east azerbaijan (ea) and west azerbaijan (wa) ...

estimation of weed damage threshold is essensial in site-specific weed control programs. this experiment was conducted to determine the spatial distribution of weeds damage threshold in two wheat feilds. data related to weed biomass and crop yield were collected from sampling at 120 and 135 points of the first and second fields respectively based on a 4×4 m grid at research field of agricultura...

palmprint recognition is a new biometrics system based on physiological characteristics of the palmprint, which includes rich, stable, and unique features such as lines, points, and texture. texture is one of the most important features extracted from low resolution images. in this paper, a new local descriptor, local composition derivative pattern (lcdp) is proposed to extract smartly stronger...

Background: Many elderly individuals complain of difficulty in understanding speech in noise despite having normal hearing thresholds. According to previous studies, auditory training leads to improvement in speech-in-noise perception, but these studies did not consider the etiology, so their results cannot be generalized. The present study aimed at investigating the effectiveness of envelope-b...

We compare the individual-based "threshold model" of innovation diffusion in the version which has been studied by Young (1998), with an aggregate model we derived from it. This model allows us to formalise and test hypotheses on the influence of individual characteristics upon global evolution. The classical threshold model supposes that an individual adopts a behaviour according to a trade-of...

Functional quality of the student residence halls has a great deal of importance due to their collective nature and the fact that they are considered as housing units, identifying and defining the role of intermediary spaces on the spatial organization and and spatial consociation of student residence halls which is a compound system of masses and spatial borderlines can bring order to its syst...

Image fusion is a method for obtaining a highly informative image by merging the relative information of an object obtained from two or more image sources of the same scene. The satellite cameras give a single band panchromatic (PAN) image with high spatial information and multispectral (MS) image with more spectral information. The problem exists today is either PAN or MS image is available fr...
