A Gaussian correction scheme is proposed and a G-PSO algorithm is proposed. Through the introduction of Gaussian coefficients, we modify the fitness function of PSO algorithm, the particle individual velocity and the position updating strategy. Furthermore, two test functions are used to analyze the performance of G-PSO algorithm to solve the global optimal solution. Experimental results of vir...

Background and Purpose: Implementing the guidelines to prevent VAP has been shown to have a significant effect on reducing the incidence of VAP. Studies indicate that ICU staff have poor knowledge and low implementation rate of the standard preventive measures related to VAP. The present study aims to evaluate the knowledge of nurses in the intensive care unit in University hospitals of Sari. ...

Human error is a significant and ever-growing problem in the healthcare sector. In this study, resource allocation problem is considered along with human errors to optimize utilization of resources in an emergency department. The algorithm is composed of simulation, artificial neural network (ANN), design of experiment (DOE) and fuzzy data envelopment analysis (FDEA). It is a multi-response opt...

background: health technology assessment (hta) is a tool utilized for efficient dissemination of technology. for the purpose of encouraging decision-makers to utilize this tool, at first, we need to identify the obstacles in the processes of preparation, utilization, and implementation of htas. this study aims to define these barriers and offer solutions for effective utilization of hta reports...

Model updating concerns the modification of an existing but inaccurate model with measured data. For models characterized by quadratic pencils, the measured data usually involve incomplete knowledge of natural frequencies, mode shapes, or other spectral information. In conducting the updating, it is often desirable to match only the part of observed data without tampering with the other part of...

Accurate metacognitive knowledge is vital for optimal performance in self-regulated learning. Yet older adults have deficiencies in implementing effective learning strategies and knowledge updating and consequently may not learn as effectively from task experience as younger adults. Here we assess the ability of older adults to update metacognitive knowledge about the effects of word frequency ...
