in this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (lims). dynamical equations of lim have been considered accurate. in other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. then equations of the reference model and adaptive mode...

Census counts are subject to different types of nonsampling errors. One of these main errors is coverage error. Undercount and overcount are two types of coverage error. Undercount usually occurs more than the other, thus net undercount estimation is important. There are various methods for estimating the coverage error in censuses. One of these methods is dual system (DS) that usually uses dat...

Statins have revolutionised modern cardiovascular treatment by producing a striking reduction in coronary risk. In 2005, the Cholesterol Treatment Trialists’ (CTT) collaboration reported a meta-analysis of 14 random ised trials (including about 90 000 patients) of statin versus placebo that recorded a 20% relative risk reduc tion in major vascular events (comprising coronary death, nonfatal myo...

supply chain management is one of the main factors of successful organization. one of the important causes of its’ ineffectiveness is “bullwhip effect”. most of previous studies were about its’ effect on one-product and two-echelon chains. in this paper, the authors try to study bullwhip effect on two and three-echelon chains which includes more than one product according to some assumptions. t...

background: in pediatric resuscitation, it is necessary to distinguish the weight in order to provide proper doses of drugs, equipment selection, and ventilator settings, therefore, access to a simple, unbiased, and accurate formula can decrease mistakes. the aim of this study is to determine the percentage of error (pe) of different weight estimation methods toward actual weight in children  a...

Abstract This paper delivers an analysis of the least-squares estimation of the Laguerre coefficients of a linear discrete-time system from step response data. The original contribution consists in an explicit formula for the bias error on the estimated coefficients due to the under-modelling of the system. The formula, jointly with some a-priori information on the neglected dynamics, can be us...
