With the development of industry, physical model controlled object tends to be complicated and unknown. It is particularly important estimate state variables a nonlinear system when This paper proposes estimation method based on adaptive fusion multiple kernel functions improve accuracy estimation. First, dynamic neural network used build model, where function node constructed by weighted linea...

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 adm...

Predictions and quality management issues for environmental protection in river basins rely on water-quality models. These models can be used to simulate conditions in or near the range of the calibrated or verified conditions. In this respect, estimation of parameters, which is still practiced by heuristic approaches (i.e. manually), seems to be the point where the attention needs to be focuse...

The aim of this retrospective study was to evaluate the accuracy of gynecology and obstetrics residents when performing ultrasonographic estimation of fetal weight. The total of 400 ultrasonographic estimations of fetal weight and corresponding neonatal weight were collected and divided into 3 groups according to physicians' experience (junior and senior residents, staff physicians). The accura...

CONTEXT AND OBJECTIVE Accurate fetal weight estimation is important for labor and delivery management. So far, there has not been any conclusive evidence to indicate that any technique for fetal weight estimation is superior to any other. Clinical formulas for fetal weight estimation are easy to use but have not been extensively studied in the literature. This study aimed to evaluate the accura...

The perturbation method is applied to numerical solution of the Lane-Emden Equation (LEE)of arbitrary index n, and the global parameters of polytropes are found as function of polytropic index n.

ports are the most important economic, political and military bottlenecks. this puts shoreline structures (port) in the class of important structures and they have a crucial role in the countries’ life. pile and deck wharf and their access bridges and offshore deck (jetties), are one of the parts which are supplier of coupling between the land and the waterfront. correct and exact estimation of...
