استفاده از معیارهای پایا در طراحی الگوریتمها و بررسی عملکرد آنها جایگاهی ویژه در دانش مخابرات و کنترل دارد. یک معیار مناسب در طراحی الگوریتمهای وفقی پایا نرم h می باشد. با استفاده از این نرم و با در نظر گرفتن سرعت تغییرات پارامتر در یک مدل کاربردی دو الگوریتم در رده الگوریتمهای lms و (least mean squared) و (normalized lms) nlms با عنوانهای (second order lms) slms و (second ...
eunsteady slip-flow of second grade non-newtonian electrically conducting fluid over an oscillating sheet has been considered and solved numerically. a second-order slip velocity model is used to predict the flow characteristic over the wall. with the assumption of infinite length in the x-direction, the velocity of the fluid can be assumed as a function of y and t, hence, with proper change va...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
the purpose of this study is identifying effective factors which make customers shop online in iran and investigating the importance of discovered factors in online customers’ decision. in the identifying phase, to discover the factors affecting online shopping behavior of customers in iran, the derived reference model summarizing antecedents of online shopping proposed by change et al. was us...
We determine a constitutive equation for developed three-dimensional granular flows based on series of discrete element method simulations. In order to capture non-local phenomena, normal stress differences, and secondary flows, we extend previously proposed temperature-sensitive rheological model by considering Rivlin-Ericksen tensors up second order. Three parameters are calibrated with the i...
