In this paper, the gain in LD-CELP speech coding algorithm is predicted using three neural models, that are equipped by genetic and particle swarm optimization (PSO) algorithms to optimize the structure and parameters of neural networks. Elman, multi-layer perceptron (MLP) and fuzzy ARTMAP are the candidate neural models. The optimized number of nodes in the first and second hidden layers of El...

introduction lori sheep is one of the most important breeds in iran that is mostly bred in lorestan province, north-east of khuzestan and some areas of ilam provinces. the name of this breed is derived from lori tribe, which is one of the major nomadic groups of zagros mountain in western areas of iran. lori sheep is resistant to mountain conditions and hot and dry plains. this sheep breed has ...

The objective of this study was to compare different implementations of genomic selection to a conventional maternal pig breeding scheme, when selection was based partly on production traits and partly on maternal traits. A nucleus pig breeding population with size and structure similar to Norwegian Landrace was simulated where equal weight was used for maternal and production traits. To genoty...

a deterministic model was employed to simulate various progeny testing programs compatible with the conditions of holstein dairy cattle population in iran. in simulated programs, the selection intensity of bulls was increased by increasing the ratio of cow population in mate with young bulls. selection accuracy in the programs was fixed because of the fixed progeny group. economic efficiency (t...

The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in 16 winter rapeseed genotypes. Statistical analysis showed significant differences ...

خلاصه فارسی: به علت وجود مشکلات استفاده از داروهایی با نیمه عمر کوتاه که نیازمند تجویز چند دوز در طی یک روز می باشند، مانند فراموش کردن دریافت دوز دارو و ثابت نبودن سطح خونی و... ضرورت ساخت اشکال modified release واضح و مبرهن است. از میان راه های مختلف دارورسانی به بدن، راه خوراکی به علت مزایای ویژه خود همچنان از جایگاه مهمی در داروسازی برخوردار می باشد. اشکال دارویی متنوعی نیز این امکان را فر...

To estimate heritability, and genetic and phenotypic relationships and also to study the effect of sex and rearing environment on body weight, weight gain, feed consumption and feed conversion coefficient, the data from 1200 pedigreed male and female chickens from three genetic groups including 90 sires were used. The included genetic groups were crosses of native chickens and an exotic breed (...
