abstract: the present study was undertaken to investigate whether 1) there is any significant correlation between iranian efl/eap learners’ l2 writing proficiency and their willingness to communicate, 2) there is any significant difference between efl and eap learners in terms of willingness to communicate, 3) there is any significant difference in wtc of iranian efl/eap learners with 1- nati...
Differential space-time coding (DSTC) has receivedmuch interest as it obviates the requirement of the channel state information at the receiver while maintaining the desired properties of space-time coding techniques. In this paper, by introducing star quadrature amplitude modulation (star QAM) method, two kinds of multiple amplitudes DSTC schemes are proposed. One is based on differential unit...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
the aim of this study was to analyze the effect of sex, season and year of birth on growth rate of biometric measurements and body weight gain of thoroughbred foals during first six months of life. 103 thoroughbred foals (53 colts and 50 fillies) from golejewko stud born between 2006 and 2008, were used in this study. thoroughbred foals born in winter months were characterized by significantly ...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
The present study examined the effect of date pits powder as a low-cost and nutritive carbohydrate source compared to wheat, rice and corn meal in the diet of Pacific shrimp. The date pits meal was applied to the diet at the levels of 0 (control group), 5, 10, 15 and 23%, and the growth performance of shrimp was examined in 8 weeks. The results showed that the weight and length gain, specific g...
Despite providing robustness, high-gain observers impose a peaking phenomenon, which may cause instability, on the system states. In this paper, an adaptive saturation is proposed to attenuate the undesirable mentioned phenomenon in high-gain observers. A real-valued and differentiable sigmoid function is considered as the saturating element whose parameters (height and slope) are adaptively tu...
AIM To study the effect of Kangaroo mother care in the Kangaroo ward in comparison with conventional care at neonatal unit on growth and breastfeeding in very low birth weight infants at 40 weeks' corrected gestational age. METHODS One hundred and forty neonates with birth weight <1500 g were randomized. The primary outcome was the average weight gain (g/kg/day) from the time of randomization...
